class="card-text"><strong>Abstract:</strong></p> A methodology to estimate the state-of-charge (SOC) of battery electric buses, including degradation effects, for a given driving cycle is presented to support long-term techno-economic analysis integrating electric buses and charging infrastructure. The degradation mechanisms, characterized by both capacity and power fade with time, have been modeled using an electrochemical model for Li-ion batteries. Iterative changes in the negative electrode film resistance and decrease in available lithium as a function of utilization is simulated for every cycle. The cycles are formulated to follow typical transit bus driving patterns. The power and capacity decay resulting from the degradation model are introduced as inputs to a longitudinal chassis dynamic analysis that calculates the power consumption of the bus for a given driving cycle to find the state-of-charge of the battery as a function of time. The method is applied to an in-depot charging scenario, for which the bus is charged exclusively at the depot, overnight and to its full capacity. This scenario is run both with and without including degradation effects over time to illustrate the significant impact of degradation mechanisms on bus performance when doing feasibility studies for a fleet of electric buses. The impact of battery degradation on battery lifetime is also assessed. The modeling tool can be further used to optimize component sizing and charging locations for electric bus deployment projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=battery%20electric%20bus" title="battery electric bus">battery electric bus</a>, <a href="https://publications.waset.org/abstracts/search?q=E-bus" title=" E-bus"> E-bus</a>, <a href="https://publications.waset.org/abstracts/search?q=in-depot%20charging" title=" in-depot charging"> in-depot charging</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20battery" title=" lithium-ion battery"> lithium-ion battery</a>, <a href="https://publications.waset.org/abstracts/search?q=battery%20degradation" title=" battery degradation"> battery degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=capacity%20fade" title=" capacity fade"> capacity fade</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20fade" title=" power fade"> power fade</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicle" title=" electric vehicle"> electric vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=SEI" title=" SEI"> SEI</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20models" title=" electrochemical models"> electrochemical models</a> </p> <a href="https://publications.waset.org/abstracts/57537/modeling-battery-degradation-for-electric-buses-assessment-of-lifespan-reduction-from-in-depot-charging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57537.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">325</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2358</span> Identifying Degradation Patterns of LI-Ion Batteries from Impedance Spectroscopy Using Machine Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yunwei%20Zhang">Yunwei Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Qiaochu%20Tang"> Qiaochu Tang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yao%20Zhang"> Yao Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiabin%20Wang"> Jiabin Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ulrich%20Stimming"> Ulrich Stimming</a>, <a href="https://publications.waset.org/abstracts/search?q=Alpha%20Lee"> Alpha Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Forecasting the state of health and remaining useful life of Li-ion batteries is an unsolved challenge that limits technologies such as consumer electronics and electric vehicles. Here we build an accurate battery forecasting system by combining electrochemical impedance spectroscopy (EIS) -- a real-time, non-invasive and information-rich measurement that is hitherto underused in battery diagnosis -- with Gaussian process machine learning. We collect over 20,000 EIS spectra of commercial Li-ion batteries at different states of health, states of charge and temperatures -- the largest dataset to our knowledge of its kind. Our Gaussian process model takes the entire spectrum as input, without further feature engineering, and automatically determines which spectral features predict degradation. Our model accurately predicts the remaining useful life, even without complete knowledge of past operating conditions of the battery. Our results demonstrate the value of EIS signals in battery management systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=battery%20degradation" title="battery degradation">battery degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning%20method" title=" machine learning method"> machine learning method</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20impedance%20spectroscopy" title=" electrochemical impedance spectroscopy"> electrochemical impedance spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=battery%20diagnosis" title=" battery diagnosis"> battery diagnosis</a> </p> <a href="https://publications.waset.org/abstracts/123383/identifying-degradation-patterns-of-li-ion-batteries-from-impedance-spectroscopy-using-machine-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123383.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2357</span> An Equivalent Circuit Model Approach for Battery Pack Simulation in a Hybrid Electric Vehicle System Powertrain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suchitra%20Sivakumar">Suchitra Sivakumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hajime%20Shingyouchi"> Hajime Shingyouchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Toshinori%20Okajima"> Toshinori Okajima</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyohei%20Yamaguchi"> Kyohei Yamaguchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin%20Kusaka"> Jin Kusaka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The progressing need for powertrain electrification calls for more accurate and reliable simulation models. A battery pack serves as the most vital component for energy storage in an electrified powertrain. Hybrid electric vehicles (HEV) do not behave the same way as they age, and there are several environmental factors that account for the degradation of the battery on a system level. Therefore, in this work, a battery model was proposed to study the state of charge (SOC) variation and the internal dynamic changes that contribute to aging and performance degradation in HEV batteries. An equivalent circuit battery model (ECM) is built using MATLAB Simulink to investigate the output characteristics of the lithium-ion battery. The ECM comprises of circuit elements like a voltage source, a series resistor and a parallel RC network connected in series. A parameter estimation study is conducted on the ECM to study the dependencies of the circuit elements with the state of charge (SOC) and the terminal voltage of the battery. The battery model is extended to simulate the temperature dependence of the individual battery cell and the battery pack with the environment. The temperature dependence model accounts for the heat loss due to internal resistance build up in the battery pack during charging, discharging, and due to atmospheric temperature. The model was validated for a lithium-ion battery pack with an independent drive cycle showing a voltage accuracy of 4% and SOC accuracy of about 2%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=battery%20model" title="battery model">battery model</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20electric%20vehicle" title=" hybrid electric vehicle"> hybrid electric vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20battery" title=" lithium-ion battery"> lithium-ion battery</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20model" title=" thermal model"> thermal model</a> </p> <a href="https://publications.waset.org/abstracts/113330/an-equivalent-circuit-model-approach-for-battery-pack-simulation-in-a-hybrid-electric-vehicle-system-powertrain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113330.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">298</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2356</span> Autonomic Management for Mobile Robot Battery Degradation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martin%20Doran">Martin Doran</a>, <a href="https://publications.waset.org/abstracts/search?q=Roy%20Sterritt"> Roy Sterritt</a>, <a href="https://publications.waset.org/abstracts/search?q=George%20Wilkie"> George Wilkie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The majority of today’s mobile robots are very dependent on battery power. Mobile robots can operate untethered for a number of hours but eventually they will need to recharge their batteries in-order to continue to function. While computer processing and sensors have become cheaper and more powerful each year, battery development has progress very little. They are slow to re-charge, inefficient and lagging behind in the general progression of robotic development we see today. However, batteries are relatively cheap and when fully charged, can supply high power output necessary for operating heavy mobile robots. As there are no cheap alternatives to batteries, we need to find efficient ways to manage the power that batteries provide during their operational lifetime. This paper proposes the use of autonomic principles of self-adaption to address the behavioral changes a battery experiences as it gets older. In life, as we get older, we cannot perform tasks in the same way as we did in our youth; these tasks generally take longer to perform and require more of our energy to complete. Batteries also suffer from a form of degradation. As a battery gets older, it loses the ability to retain the same charge capacity it would have when brand new. This paper investigates how we can adapt the current state of a battery charge and cycle count, to the requirements of a mobile robot to perform its tasks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autonomic" title="autonomic">autonomic</a>, <a href="https://publications.waset.org/abstracts/search?q=self-adaptive" title=" self-adaptive"> self-adaptive</a>, <a href="https://publications.waset.org/abstracts/search?q=self-optimising" title=" self-optimising"> self-optimising</a>, <a href="https://publications.waset.org/abstracts/search?q=degradation" title=" degradation"> degradation</a> </p> <a href="https://publications.waset.org/abstracts/77739/autonomic-management-for-mobile-robot-battery-degradation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77739.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">385</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2355</span> Mathematical Modelling and AI-Based Degradation Analysis of the Second-Life Lithium-Ion Battery Packs for Stationary Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farhad%20Salek">Farhad Salek</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahaboddin%20Resalati"> Shahaboddin Resalati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The production of electric vehicles (EVs) featuring lithium-ion battery technology has substantially escalated over the past decade, demonstrating a steady and persistent upward trajectory. The imminent retirement of electric vehicle (EV) batteries after approximately eight years underscores the critical need for their redirection towards recycling, a task complicated by the current inadequacy of recycling infrastructures globally. A potential solution for such concerns involves extending the operational lifespan of electric vehicle (EV) batteries through their utilization in stationary energy storage systems during secondary applications. Such adoptions, however, require addressing the safety concerns associated with batteries’ knee points and thermal runaways. This paper develops an accurate mathematical model representative of the second-life battery packs from a cell-to-pack scale using an equivalent circuit model (ECM) methodology. Neural network algorithms are employed to forecast the degradation parameters based on the EV batteries' aging history to develop a degradation model. The degradation model is integrated with the ECM to reflect the impacts of the cycle aging mechanism on battery parameters during operation. The developed model is tested under real-life load profiles to evaluate the life span of the batteries in various operating conditions. The methodology and the algorithms introduced in this paper can be considered the basis for Battery Management System (BMS) design and techno-economic analysis of such technologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=second%20life%20battery" title="second life battery">second life battery</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicles" title=" electric vehicles"> electric vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=degradation" title=" degradation"> degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20network" title=" neural network"> neural network</a> </p> <a href="https://publications.waset.org/abstracts/179296/mathematical-modelling-and-ai-based-degradation-analysis-of-the-second-life-lithium-ion-battery-packs-for-stationary-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179296.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">65</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2354</span> Wireless Battery Charger with Adaptive Rapid-Charging Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Byoung-Hee%20Lee">Byoung-Hee Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wireless battery charger with adaptive rapid charging algorithm is proposed.

For the purpose of long cycle life of vanadium redox battery (VRB), the chemical stability of Im-bPPO, sPPO (sulfonated 2,6-dimethyl-1,4-phenylene oxide) and Fumatech membranes were evaluated firstly in the 0.1M vanadium (V) solution dissolved in 3M sulfuric acid (H2SO4) for 72h, and UV analyses of the degradation products proved that ether bond in PPO backbone was vulnerable to be attacked by vanadium (V) ion. It was found that the membranes had slightly weight loss after soaking in 2 ml distilled water included in STS pressure vessel for 1 day at 200◦C. ATR-FT-IR data indicated before and after the degradation of the membranes. Further evaluation on the degradation mechanism of the menbranes were carried out in Fenton’s reagent solution for 72 h at 50 ◦C and analyses of the membranes before and after degradation confirmed the weight loss of the membranes. The Fumatech membranes exhibited better performance than AEM and CEM, but Nafion 212 still suffers chemical degradation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vanadium%20redox%20flow%20battery" title="vanadium redox flow battery">vanadium redox flow battery</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20exchange%20membrane" title=" ion exchange membrane"> ion exchange membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=permeability" title=" permeability"> permeability</a>, <a href="https://publications.waset.org/abstracts/search?q=degradation" title=" degradation"> degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20stability" title=" chemical stability"> chemical stability</a> </p> <a href="https://publications.waset.org/abstracts/44968/chemical-stability-and-characterization-of-ion-exchange-membranes-for-vanadium-redox-flow-batteries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44968.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">299</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2352</span> Optimal Portfolio of Multi-service Provision based on Stochastic Model Predictive Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yifu%20Ding">Yifu Ding</a>, <a href="https://publications.waset.org/abstracts/search?q=Vijay%20Avinash"> Vijay Avinash</a>, <a href="https://publications.waset.org/abstracts/search?q=Malcolm%20McCulloch"> Malcolm McCulloch</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As the proliferation of decentralized energy systems, the UK power system allows small-scale entities such as microgrids (MGs) to tender multiple energy services including energy arbitrage and frequency responses (FRs). However, its operation requires the balance between the uncertain renewable generations and loads in real-time and has to fulfill their provision requirements of contract services continuously during the time window agreed, otherwise it will be penalized for the under-delivered provision. To hedge against risks due to uncertainties and maximize the economic benefits, we propose a stochastic model predictive control (SMPC) framework to optimize its operation for the multi-service provision. Distinguished from previous works, we include a detailed economic-degradation model of the lithium-ion battery to quantify the costs of different service provisions, as well as accurately describe the changing dynamics of the battery. Considering a branch of load and generation scenarios and the battery aging, we formulate a risk-averse cost function using conditional value at risk (CVaR). It aims to achieve the maximum expected net revenue and avoids severe losses. The framework will be performed on a case study of a PV-battery grid-tied microgrid in the UK with real-life data. To highlight its performance, the framework will be compared with the case without the degradation model and the deterministic formulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=model%20predictive%20control%20%28MPC%29" title="model predictive control (MPC)">model predictive control (MPC)</a>, <a href="https://publications.waset.org/abstracts/search?q=battery%20degradation" title=" battery degradation"> battery degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency%20response" title=" frequency response"> frequency response</a>, <a href="https://publications.waset.org/abstracts/search?q=microgrids" title=" microgrids"> microgrids</a> </p> <a href="https://publications.waset.org/abstracts/114565/optimal-portfolio-of-multi-service-provision-based-on-stochastic-model-predictive-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114565.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">122</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2351</span> Offline Parameter Identification and State-of-Charge Estimation for Healthy and Aged Electric Vehicle Batteries Based on the Combined Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xiaowei%20Zhang">Xiaowei Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Xu"> Min Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeid%20Habibi"> Saeid Habibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Fengjun%20Yan"> Fengjun Yan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ryan%20Ahmed"> Ryan Ahmed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, Electric Vehicles (EVs) have received extensive consideration since they offer a more sustainable and greener transportation alternative compared to fossil-fuel propelled vehicles. Lithium-Ion (Li-ion) batteries are increasingly being deployed in EVs because of their high energy density, high cell-level voltage, and low rate of self-discharge. Since Li-ion batteries represent the most expensive component in the EV powertrain, accurate monitoring and control strategies must be executed to ensure their prolonged lifespan. The Battery Management System (BMS) has to accurately estimate parameters such as the battery State-of-Charge (SOC), State-of-Health (SOH), and Remaining Useful Life (RUL). In order for the BMS to estimate these parameters, an accurate and control-oriented battery model has to work collaboratively with a robust state and parameter estimation strategy. Since battery physical parameters, such as the internal resistance and diffusion coefficient change depending on the battery state-of-life (SOL), the BMS has to be adaptive to accommodate for this change. In this paper, an extensive battery aging study has been conducted over 12-months period on 5.4 Ah, 3.7 V Lithium polymer cells. Instead of using fixed charging/discharging aging cycles at fixed C-rate, a set of real-world driving scenarios have been used to age the cells. The test has been interrupted every 5% capacity degradation by a set of reference performance tests to assess the battery degradation and track model parameters. As battery ages, the combined model parameters are optimized and tracked in an offline mode over the entire batteries lifespan. Based on the optimized model, a state and parameter estimation strategy based on the Extended Kalman Filter (EKF) and the relatively new Smooth Variable Structure Filter (SVSF) have been applied to estimate the SOC at various states of life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20batteries" title="lithium-ion batteries">lithium-ion batteries</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm%20optimization" title=" genetic algorithm optimization"> genetic algorithm optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=battery%20aging%20test" title=" battery aging test"> battery aging test</a>, <a href="https://publications.waset.org/abstracts/search?q=parameter%20identification" title=" parameter identification"> parameter identification</a> </p> <a href="https://publications.waset.org/abstracts/52283/offline-parameter-identification-and-state-of-charge-estimation-for-healthy-and-aged-electric-vehicle-batteries-based-on-the-combined-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52283.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">267</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2350</span> A Data Driven Approach for the Degradation of a Lithium-Ion Battery Based on Accelerated Life Test </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alyaa%20M.%20Younes">Alyaa M.

Their ability to store relatively large amount of energy in a limited space make them most appropriate for critical applications. Evaluation of the life of these batteries and their reliability becomes crucial to the systems they support. Reliability of Li-Ion batteries has been mainly considered based on its lifetime. However, another important factor that can be considered critical in many applications such as in electric vehicles is the cycle duration. The present work presents the results of an experimental investigation on the degradation behavior of a Laptop Li-ion battery (type TKV2V) and the effect of applied load on the battery cycle time. The reliability was evaluated using an accelerated life test. Least squares linear regression with median rank estimation was used to estimate the Weibull distribution parameters needed for the reliability functions estimation. The probability density function, failure rate and reliability function under each of the applied loads were evaluated and compared. An inverse power model is introduced that can predict cycle time at any stress level given. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accelerated%20life%20test" title="accelerated life test">accelerated life test</a>, <a href="https://publications.waset.org/abstracts/search?q=inverse%20power%20law" title=" inverse power law"> inverse power law</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20battery" title=" lithium-ion battery"> lithium-ion battery</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability%20evaluation" title=" reliability evaluation"> reliability evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=Weibull%20distribution" title=" Weibull distribution"> Weibull distribution</a> </p> <a href="https://publications.waset.org/abstracts/108960/a-data-driven-approach-for-the-degradation-of-a-lithium-ion-battery-based-on-accelerated-life-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108960.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">168</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2349</span> Stabilizing of Lithium-Solid-Electrolyte Interfaces by Atomic Layer Deposition Prepared Nano-Interlayers for a Model All-Solid-State Battery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rainer%20Goetz">Rainer Goetz</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Ahaliabadeh"> Zahra Ahaliabadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Princess%20S.%20Llanos"> Princess S.

A model battery is needed whose characterization is independent of the influence of the complex battery assembly. Lithium-Ion Conducting Glass-Ceramic (LICGC), a model solid electrolyte, is chosen for its stability in the air, but on the other hand, it is also well-known for its instability against metallic lithium upon direct contact. Hence, as a first step towards a model ASSB, the interface between lithium and the solid electrolyte (SE) is stabilized with thin (5 nm and 10 nm) coatings of titanium oxide (TO) and lithium titanium oxide (LTO). Impedance data shows that both materials are able to protect the SE surface from rapid degradation due to reducing lithium and, therefore, can serve as a protective interlayer on the anode side of a model ASSB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=all-solid-state%20battery" title="all-solid-state battery">all-solid-state battery</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium%20anode" title=" lithium anode"> lithium anode</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20electrolytes" title=" solid electrolytes"> solid electrolytes</a>, <a href="https://publications.waset.org/abstracts/search?q=interlayers" title=" interlayers"> interlayers</a> </p> <a href="https://publications.waset.org/abstracts/163463/stabilizing-of-lithium-solid-electrolyte-interfaces-by-atomic-layer-deposition-prepared-nano-interlayers-for-a-model-all-solid-state-battery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163463.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">115</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2348</span> Adaptive Discharge Time Control for Battery Operation Time Enhancement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jong-Bae%20Lee">Jong-Bae Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Seongsoo%20Lee"> Seongsoo Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes an adaptive discharge time control method to balance cell voltages in alternating battery cell discharging method. In the alternating battery cell discharging method, battery cells are periodically discharged in turn. Recovery effect increases battery output voltage while the given battery cell rests without discharging, thus battery operation time of target system increases. However, voltage mismatch between cells leads two problems. First, voltage difference between cells induces inter-cell current with wasted power. Second, it degrades battery operation time, since system stops when any cell reaches to the minimum system operation voltage. To solve this problem, the proposed method adaptively controls cell discharge time to equalize both cell voltages. In the proposed method, battery operation time increases about 19%, while alternating battery cell discharging method shows about 7% improvement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=battery" title="battery">battery</a>, <a href="https://publications.waset.org/abstracts/search?q=recovery%20effect" title=" recovery effect"> recovery effect</a>, <a href="https://publications.waset.org/abstracts/search?q=low-power" title=" low-power"> low-power</a>, <a href="https://publications.waset.org/abstracts/search?q=alternating%20battery%20cell%20discharging" title=" alternating battery cell discharging"> alternating battery cell discharging</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptive%20discharge%20time%20control" title=" adaptive discharge time control"> adaptive discharge time control</a> </p> <a href="https://publications.waset.org/abstracts/2374/adaptive-discharge-time-control-for-battery-operation-time-enhancement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2374.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">352</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2347</span> Reducing Change-Related Costs in Assembly of Lithium-Ion Batteries for Electric Cars by Mechanical Decoupling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Achim%20Kampker">Achim Kampker</a>, <a href="https://publications.waset.org/abstracts/search?q=Heiner%20Hans%20Heimes"> Heiner Hans Heimes</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathias%20Ordung"> Mathias Ordung</a>, <a href="https://publications.waset.org/abstracts/search?q=Nemanja%20Sarovic"> Nemanja Sarovic</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A key component of the drive train of electric vehicles is the lithium-ion battery system.

Types of batteries have been developed using MnO<sub>2</sub> in various ways. MnO<sub>2 </sub>is suitable with physical, chemical, electrochemical, and catalytic properties, serving as an effective cathodic depolarizer and may be considered as being the life blood of the battery systems. In the present experimental work, we have studied the effect of generation of power by bio-battery using different concentrations of MnO<sub>2</sub>. The tests show that it is possible to generate electricity using cow’s urine as an electrolyte. After ascertaining the optimum concentration of MnO<sub>2</sub>, various battery parameters and performance indicates that cow urine solely produces power of 695 mW, while a combination with MnO<sub>2</sub> (40%) enhances power of bio-battery, i.e. 1377 mW. On adding more and more MnO<sub>2 </sub>to the electrolyte, the power suppressed because inflation of internal resistance. The analysis of the data produced from experiment shows that MnO<sub>2</sub> is quite suitable to energize the bio-battery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-batteries" title="bio-batteries">bio-batteries</a>, <a href="https://publications.waset.org/abstracts/search?q=cow%E2%80%99s%20urine" title=" cow’s urine"> cow’s urine</a>, <a href="https://publications.waset.org/abstracts/search?q=manganese%20dioxide" title=" manganese dioxide"> manganese dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=non-conventional" title=" non-conventional"> non-conventional</a> </p> <a href="https://publications.waset.org/abstracts/81623/customized-cows-urine-battery-using-mno2-depolarizer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81623.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">261</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2345</span> Thin and Flexible Zn-Air Battery by Inexpensive Screen Printing Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sira%20Suren">Sira Suren</a>, <a href="https://publications.waset.org/abstracts/search?q=Soorathep%20Kheawhom"> Soorathep Kheawhom</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work focuses the development of thin and flexible zinc-air battery.

Therefore, research for utilizing nuclear energy in the universe has been in progress since the 1950s, around the major industrialized countries. In this study, the self-rechargeable battery having a long life relative to the half-life of the radioisotope is suggested. The hybrid system is composed of betavoltaic battery, all solid battery and energy harvesting board. Betavoltaic battery can produce electrical power at least 10 years over using the radioisotope from Ni-63 and the silicon-based semiconductor. The electrical power generated from the betavoltaic battery is stored in the all-solid battery and stored power is used if necessary. The hybrid system board is composed of input terminals, boost circuit, charging terminals and output terminals. Betavoltaic and all solid batteries are connected to the input and output terminal, respectively. The electric current of 10 µA is applied to the system board by using the high-resolution power simulator. The system efficiencies are measured from a boost up voltage of 1.8 V, 2.4 V and 3 V, respectively. As a result, the efficiency of system board is about 75% after boosting up the voltage from 1V to 3V. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=isotope" title="isotope">isotope</a>, <a href="https://publications.waset.org/abstracts/search?q=betavoltaic" title=" betavoltaic"> betavoltaic</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear" title=" nuclear"> nuclear</a>, <a href="https://publications.waset.org/abstracts/search?q=battery" title=" battery"> battery</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20harvesting" title=" energy harvesting"> energy harvesting</a> </p> <a href="https://publications.waset.org/abstracts/50011/a-study-on-long-life-hybrid-battery-system-consists-of-ni-63-betavoltaic-battery-and-all-solid-battery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50011.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">327</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2343</span> Investigation and Estimation of State of Health of Battery Pack in Battery Electric Vehicles-Online Battery Characterization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Mashayekh">Ali Mashayekh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdiye%20Khorasani"> Mahdiye Khorasani</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Weyh"> Thomas Weyh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The tendency to use the Battery-Electric vehicle (BEV) for the low and medium driving range or even high driving range has been growing more and more. As a result, higher safety, reliability, and durability of the battery pack as a component of electric vehicles, which has a great share of cost and weight of the final product, are the topics to be considered and investigated. Battery aging can be considered as the predominant factor regarding the reliability and durability of BEV. To better understand the aging process, offline battery characterization has been widely used, which is time-consuming and needs very expensive infrastructures. This paper presents the substitute method for the conventional battery characterization methods, which is based on battery Modular Multilevel Management (BM3). According to this Topology, the battery cells can be drained and charged concerning their capacity, which allows varying battery pack structures. Due to the integration of the power electronics, the output voltage of the battery pack is no longer fixed but can be dynamically adjusted in small steps. In other words, each cell can have three different states, namely series, parallel, and bypass in connection with the neighbor cells. With the help of MATLAB/Simulink and by using the BM3 modules, the battery string model is created. This model allows us to switch two cells with the different SoC as parallel, which results in the internal balancing of the cells. But if the parallel switching lasts just for a couple of ms, we can have a perturbation pulse which can stimulate the cells out of the relaxation phase. With the help of modeling the voltage response pulse of the battery, it would be possible to characterize the cell. The Online EIS method, which is discussed in this paper, can be a robust substitute for the conventional battery characterization methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=battery%20characterization" title="battery characterization">battery characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=SoH%20estimation" title=" SoH estimation"> SoH estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=RLS" title=" RLS"> RLS</a>, <a href="https://publications.waset.org/abstracts/search?q=BEV" title=" BEV"> BEV</a> </p> <a href="https://publications.waset.org/abstracts/144193/investigation-and-estimation-of-state-of-health-of-battery-pack-in-battery-electric-vehicles-online-battery-characterization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144193.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">149</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2342</span> Estimation of the State of Charge of the Battery Using EFK and Sliding Mode Observer in MATLAB-Arduino/Labview</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mouna%20Abarkan">Mouna Abarkan</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelillah%20Byou"> Abdelillah Byou</a>, <a href="https://publications.waset.org/abstracts/search?q=Nacer%20M%27Sirdi"> Nacer M'Sirdi</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Hossain%20Abarkan"> El Hossain Abarkan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the estimation of the state of charge of the battery using two types of observers.

Improvements in lithium-ion battery technology allow electric vehicles to be capable of traveling long distances. The batteries are capable of being charged faster, allowing for a sufficient range in shorter amounts of time. With increased reliance on battery technology and the changes in vehicle power trains, new challenges arise from this. Resulting electric vehicle fires caused by collisions are potentially more dangerous than those of the typical internal combustion engine. To further reduce the battery failures involved with side collisions, this project intends to reinforce an existing battery pack of an electric vehicle with honeycomb structures such that intrusion into the batteries can be minimized with weight restrictions in place. Honeycomb structures of hexagonal geometry are implemented into the side extrusions of the battery pack. With the use of explicit dynamics simulations performed in ANSYS, quantitative results such as deformation, strain, and stress are used to compare the performance of the battery pack with and without the implemented honeycomb structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=battery%20pack" title="battery pack">battery pack</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicle" title=" electric vehicle"> electric vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=honeycomb" title=" honeycomb"> honeycomb</a>, <a href="https://publications.waset.org/abstracts/search?q=side%20impact" title=" side impact"> side impact</a> </p> <a href="https://publications.waset.org/abstracts/162975/reinforcement-of-an-electric-vehicle-battery-pack-using-honeycomb-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162975.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">121</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2340</span> Comparative Ante-Mortem Studies through Electrochemical Impedance Spectroscopy, Differential Voltage Analysis and Incremental Capacity Analysis on Lithium Ion Batteries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ana%20Maria%20Igual-Munoz">Ana Maria Igual-Munoz</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Gilabert"> Juan Gilabert</a>, <a href="https://publications.waset.org/abstracts/search?q=Marta%20Garcia"> Marta Garcia</a>, <a href="https://publications.waset.org/abstracts/search?q=Alfredo%20Quijano-Lopez"> Alfredo Quijano-Lopez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, several lithium-ion battery technologies are being commercialized. These chemistries present different properties that make them more suitable for different purposes. However, comparative studies showing the advantages and disadvantages of different chemistries are incomplete or scarce. Different non-destructive techniques are currently being employed to detect how ageing affects the active materials of lithium-ion batteries (LIBs). For instance, electrochemical impedance spectroscopy (EIS) is one of the most employed ones. This technique allows the user to identify the variations on the different resistances present in LIBs. On the other hand, differential voltage analysis (DVA) has shown to be a powerful technique to detect the processes affecting the different capacities present in LIBs. This technique shows variations in the state of health (SOH) and the capacities for one or both electrodes depending on their chemistry. Finally, incremental capacity analysis (ICA) is a widely known technique for being capable of detecting phase equilibria. It reminds of the commonly used cyclic voltamperometry, as it allows detecting some reactions taking place in the electrodes. In these studies, a set of ageing procedures have been applied to commercial batteries of different chemistries (NCA, NMC, and LFP). Afterwards, results of EIS, DVA, and ICA have been used to correlate them with the processes affecting each cell. Ciclability, overpotential, and temperature cycling studies envisage how the charge-discharge rates, cut-off voltage, and operation temperatures affect each chemistry. These studies will serve battery pack manufacturers, as for common battery users, as they will determine the different conditions affecting cells for each of the chemistry. Taking this into account, each cell could be adjusted to the final purpose of the battery application. Last but not least, all the degradation parameters observed are focused to be integrated into degradation models in the future. This fact will allow the implementation of the widely known digital twins to the degradation in LIBs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lithium%20ion%20batteries" title="lithium ion batteries">lithium ion batteries</a>, <a href="https://publications.waset.org/abstracts/search?q=non-destructive%20analysis" title=" non-destructive analysis"> non-destructive analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=different%20chemistries" title=" different chemistries"> different chemistries</a>, <a href="https://publications.waset.org/abstracts/search?q=ante-mortem%20studies" title=" ante-mortem studies"> ante-mortem studies</a>, <a href="https://publications.waset.org/abstracts/search?q=ICA" title=" ICA"> ICA</a>, <a href="https://publications.waset.org/abstracts/search?q=DVA" title=" DVA"> DVA</a>, <a href="https://publications.waset.org/abstracts/search?q=EIS" title=" EIS"> EIS</a> </p> <a href="https://publications.waset.org/abstracts/134731/comparative-ante-mortem-studies-through-electrochemical-impedance-spectroscopy-differential-voltage-analysis-and-incremental-capacity-analysis-on-lithium-ion-batteries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134731.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">128</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2339</span> Chemical Hazards Impact on Efficiency of Energy Storage Battery and its Possible Mitigation's</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abirham%20Simeneh%20Ayalew">Abirham Simeneh Ayalew</a>, <a href="https://publications.waset.org/abstracts/search?q=Seada%20Hussen%20Adem"> Seada Hussen Adem</a>, <a href="https://publications.waset.org/abstracts/search?q=Frie%20Ayalew%20Yimam"> Frie Ayalew Yimam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Battery energy storage has a great role on storing energy harnessed from different alternative resources and greatly benefit the power sector by supply energy back to the system during outage and regular operation in power sectors.

The SOC percentage acts as a fuel gauge if it is compared with a conventional vehicle. Estimating the SOC is, therefore, essential for monitoring the amount of useful life remaining in the battery system. This paper looks at the implementation of three nonlinear estimation strategies for Li-Ion battery SOC estimation. One of the most common behavioral battery models is the one state hysteresis (OSH) model.

A wireless battery charger differs from a traditional charger in the way the power transferred to the battery. In the latter, the power is transferred through electrical wires that connect the charger terminals to the battery terminals, while in the former; the power is transferred by induction without electrical connections. With a detection algorithm that detects the battery size and chemistry, the proposed charger will be able to accommodate a wide range of applications, and will allow a more flexible and reliable option to most of today’s portable electronics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=efficiency" title="efficiency">efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetically-coupled%20resonators" title=" magnetically-coupled resonators"> magnetically-coupled resonators</a>, <a href="https://publications.waset.org/abstracts/search?q=resonance%20frequency" title=" resonance frequency"> resonance frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20power%20transfer" title=" wireless power transfer"> wireless power transfer</a> </p> <a href="https://publications.waset.org/abstracts/43549/design-of-a-universal-wireless-battery-charger" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43549.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">453</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2336</span> Renewable Integration Algorithm to Compensate Photovoltaic Power Using Battery Energy Storage System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyung%20Joo%20Lee">Hyung Joo Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin%20Young%20Choi"> Jin Young Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Gun%20Soo%20Park"> Gun Soo Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyo%20Sun%20Oh"> Kyo Sun Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong%20Jun%20Won"> Dong Jun Won</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The fluctuation of the output of the renewable generator caused by weather conditions must be mitigated because it imposes strain on the system and adversely affects power quality.

Lithium-ion battery is widely used in battery energy storage system because of its advantages of high energy density, small internal resistance, low self-discharge rate, no memory effect and long service life. However, the performance and service life of lithium-ion battery is seriously affected by its operating temperature. Thus, the safety operation of the lithium-ion battery module is inseparable from an effective thermal management system (TMS). In this study, a new type of TMS based on micro heat pipe array (MHPA) for lithium-ion battery is established, and the TMS is applied to a battery energy storage box that needs to operate at a high temperature environment of 40 °C all year round. MHPA is a flat shape metal body with high thermal conductivity and excellent temperature uniformity. The battery energy storage box is composed of four battery modules, with a nominal voltage of 51.2 V, a nominal capacity of 400 Ah. Through the excellent heat transfer characteristics of the MHPA, the heat generated by the charge and discharge process can be quickly transferred out of the battery module. In addition, if only the MHPA cannot meet the heat dissipation requirements of the battery module, the TMS can automatically control the opening of the external fan outside the battery module according to the temperature of the battery, so as to further enhance the heat dissipation of the battery module. The thermal management performance of lithium-ion battery TMS based on MHPA is studied experimentally under different ambient temperatures and the condition to turn on the fan or not. Results show that when the ambient temperature is 40 °C and the fan is not turned on in the whole charge and discharge process, the maximum temperature of the battery in the energy storage box is 53.1 °C and the maximum temperature difference in the battery module is 2.4 °C. After the fan is turned on in the whole charge and discharge process, the maximum temperature is reduced to 50.1 °C, and the maximum temperature difference is reduced to 1.7 °C. Obviously, the lithium-ion battery TMS based on MHPA not only could control the maximum temperature of the battery below 55 °C, but also ensure the excellent temperature uniformity of the battery module. In conclusion, the lithium-ion battery TMS based on MHPA can ensure the safe and stable operation of the battery energy storage box in high temperature environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20dissipation" title="heat dissipation">heat dissipation</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20battery%20thermal%20management" title=" lithium-ion battery thermal management"> lithium-ion battery thermal management</a>, <a href="https://publications.waset.org/abstracts/search?q=micro%20heat%20pipe%20array" title=" micro heat pipe array"> micro heat pipe array</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20uniformity" title=" temperature uniformity"> temperature uniformity</a> </p> <a href="https://publications.waset.org/abstracts/148328/experimental-investigation-on-the-lithium-ion-battery-thermal-management-system-based-on-micro-heat-pipe-array-in-high-temperature-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148328.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">181</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2333</span> Internet of Things Based Battery Management System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pakhil%20Singh">Pakhil Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahul%20Singh"> Rahul Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Saad%20Alam"> Mohammad Saad Alam</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasser%20Rafat"> Yasser Rafat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The battery management system is an essential package/system which ensures optimum performance and safety of a battery by monitoring the key essential parameters of the battery like the voltage, current, temperature, state of charge, state of health during charging and discharging. This can be accomplished using outputs of various sensors employed to serve the purpose. The increasing demand for electricity generation from renewable energy sources requires proper storage and hence a proper monitoring system as well. A battery management system is required in wide applications ranging from renewable energy storage systems, off-grid solar PV applications to electric vehicles. The aim of this paper is to study the parameters used in monitoring various battery operating conditions and proposes the usage of the internet of things (IoT) to implement a reliable battery management system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicles" title="electric vehicles">electric vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20of%20things" title=" internet of things"> internet of things</a>, <a href="https://publications.waset.org/abstracts/search?q=sensors" title=" sensors"> sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=state%20of%20charge" title=" state of charge"> state of charge</a>, <a href="https://publications.waset.org/abstracts/search?q=state%20of%20health" title=" state of health"> state of health</a> </p> <a href="https://publications.waset.org/abstracts/133342/internet-of-things-based-battery-management-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133342.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">197</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2332</span> Packaging Improvement for Unit Cell Vanadium Redox Flow Battery (V-RFB)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20C.%20Khor">A.

Usually the bulky battery size and low energy densities make this technology not available for mobility application. Therefore RFB with improved packaging size and energy capacity are highly desirable. This paper focuses on the study of packaging improvement for unit cell V-RFB to the application on Series Hybrid Electric Vehicle. Two different designs of 25 cm2 and 100 cm2 unit cell V-RFB at same current density are used for the sample in this investigation. Further suggestions on packaging improvement are highlighted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicle" title="electric vehicle">electric vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=redox%20flow%20battery" title=" redox flow battery"> redox flow battery</a>, <a href="https://publications.waset.org/abstracts/search?q=packaging" title=" packaging"> packaging</a>, <a href="https://publications.waset.org/abstracts/search?q=vanadium" title=" vanadium"> vanadium</a> </p> <a href="https://publications.waset.org/abstracts/10696/packaging-improvement-for-unit-cell-vanadium-redox-flow-battery-v-rfb" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10696.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">433</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2331</span> Parametric Study on Water-Cooling Plates to Improve Cooling Performance on 18650 Li-Ion Battery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raksit%20Nanthatanti">Raksit Nanthatanti</a>, <a href="https://publications.waset.org/abstracts/search?q=Jarruwat%20Charoensuk"> Jarruwat Charoensuk</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Hirai"> S.

According to the passage, enhancing the number of cooling channels[2,3,4,6channelperbases] will affect water flow distribution caused by varying the velocity inlet inside the cooling block[0.5,1.0,1.5,2.0 m/sec] and intake temperatures[25,30,35,40oC], The findings indicate that the battery’s temperature drops as the number of channels increases. The maximum battery's operating temperature [45 oC] rises, but ∆t is needed to be less than 5 oC [v≤1m/sec]. Maximum temperature and local temperature difference of the battery change significantly with the change of the velocity inlet in the cooling channel and its thermal conductivity. The results of the simulation will help to increase cooling efficiency on the cooling system for Li-ion Battery based on a Mini channel in a liquid-cooling configuration <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cooling%20efficiency" title="cooling efficiency">cooling efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=channel%20count" title=" channel count"> channel count</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20battery" title=" lithium-ion battery"> lithium-ion battery</a>, <a href="https://publications.waset.org/abstracts/search?q=operating" title=" operating"> operating</a> </p> <a href="https://publications.waset.org/abstracts/165565/parametric-study-on-water-cooling-plates-to-improve-cooling-performance-on-18650-li-ion-battery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165565.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">101</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2330</span> Battery Grading Algorithm in 2nd-Life Repurposing LI-Ion Battery System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ya%20L.%20V.">Ya L.

Most of the 2nd-life retired battery systems in the market have module/pack-level state-of-health (SOH) indicator, which is utilized for guiding appropriate depth-of-discharge (DOD) in the application of ESS. Due to the lack of cell-level SOH indication, the different degrading behaviors among various cells cannot be identified upon reaching retired status; in the end, considering end-of-life (EOL) loss and pack-level DOD, the repurposed ESS has to be oversized by > 1.5 times to complement the application requirement of reliability and cyclability. This proposed battery grading algorithm, using non-invasive methodology, is able to detect outlier cells based on historical voltage data and calculate cell-level historical maximum temperature data using semi-analytic methodology. In this way, the individual battery cell in the 2nd-life battery system can be graded in terms of SOH on basis of the historical voltage fluctuation and estimated historical maximum temperature variation. These grades will have corresponding DOD grades in the application of the repurposed ESS to enhance system reliability and cyclability. In all, this introduced battery grading algorithm is non-invasive, compatible with all kinds of retired Li-ion battery systems which lack of cell-level SOH indication, as well as potentially being embedded into battery management software for preventive maintenance and real-time cyclability optimization. <p class="card-text"><strong>Keywords:</strong> <a
