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">5354</span> Engineered Reactor Components for Durable Iron Flow Battery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Ivanovskaya">Anna Ivanovskaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandra%20E.%20L.%20Overland"> Alexandra E.

Earth-abundant iron can enable affordable grid-storage to meet DOE’s target material cost <$20/kWh and levelized cost for storage $0.05/kWh. In conventional redox flow batteries, energy is stored in external electrolyte tanks and electrolytes are circulated through the cell units to achieve electrochemical energy conversions. However, IRFBs are hybrid battery systems where metallic iron deposition at the negative side of the battery controls the storage capacity. This adds complexity to the design of a porous structure of 3D-electrodes to achieve a desired high storage capacity. In addition, there is a need to control parasitic hydrogen evolution reaction which accompanies the metal deposition process, increases the pH, lowers the energy efficiency, and limits the durability. To achieve sustainable operation of IRFBs, electrolyte pH, which affects the solubility of reactants and the rate of parasitic reactions, needs to be dynamically readjusted. In the present study we explore the impact of complexing agents on maintaining solubility of the reactants and find the optimal electrolyte conditions and battery operating regime, which are specific for IRFBs with additives, and demonstrate the robust operation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flow%20battery" title="flow battery">flow battery</a>, <a href="https://publications.waset.org/abstracts/search?q=iron-based%20redox%20flow%20battery" title=" iron-based redox flow battery"> iron-based redox flow battery</a>, <a href="https://publications.waset.org/abstracts/search?q=IRFB" title=" IRFB"> IRFB</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20storage" title=" energy storage"> energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemistry" title=" electrochemistry"> electrochemistry</a> </p> <a href="https://publications.waset.org/abstracts/168063/engineered-reactor-components-for-durable-iron-flow-battery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168063.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">78</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">5353</span> High-Performance Non-aqueous Organic Redox Flow Battery in Ambient Condition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20K.%20Mohapatra">S.

In contrast to aqueous RFBs (ARFBs), nonaqueous RFBs (NARFBs) could offer high energy densities due to the wider electrochemical window of the solvents used, which could handle high and low voltage organic redox couples without undergoing electrolysis. In this study, a RFB based on benzyl viologen hexafluorophosphate [BV(PF6)2] as anolyte and N-hexyl phenothiazine [HPT] as catholyte demonstrated. A cell operated with mixed electrolyte (1:1) containing 0.2 M [BV(PF₆)₂] and 0.2 M [HPT] delivered a coulombic efficiency (CE) of 95.3 % and energy efficiency (EE) 53%, with nearly 68.9% material utilisation at 40 mA cm-2 current density. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=non-aqueous%20redox%20flow%20battery" title="non-aqueous redox flow battery">non-aqueous redox flow battery</a>, <a href="https://publications.waset.org/abstracts/search?q=benzyl%20viologen" title=" benzyl viologen"> benzyl viologen</a>, <a href="https://publications.waset.org/abstracts/search?q=N-hexyl%20phenothiazine" title=" N-hexyl phenothiazine"> N-hexyl phenothiazine</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20electrolyte" title=" mixed electrolyte"> mixed electrolyte</a> </p> <a href="https://publications.waset.org/abstracts/165857/high-performance-non-aqueous-organic-redox-flow-battery-in-ambient-condition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165857.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">76</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">5352</span> Dimensionally Stable Anode as a Bipolar Plate for Vanadium Redox Flow Battery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaejin%20Han">Jaejin Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinsub%20Choi"> Jinsub Choi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Vanadium redox flow battery (VRFB) is a type of redox flow battery which uses vanadium ionic solution as electrolyte. Inside the VRFB, 2.5mm thickness of graphite is generally used as bipolar plate for anti-corrosion of current collector. In this research, thick graphite bipolar plate was substituted by 0.126mm thickness of dimensionally stable anode which was coated with IrO2 on an anodic nanotubular TiO2 substrate. It can provide dimensional advantage over the conventional graphite when the VRFB is used as multi-stack. Ir was coated by using spray coating method in order to enhance electric conductivity. In this study, various electrochemical characterizations were carried out. Cyclic voltammetry data showed activation of Ir in the positive electrode of VRFB. In addition, polarization measurements showed Ir-coated DSA had low overpotential in the positive electrode of VRFB. In cell test results, the DSA-used VRFB showed better efficiency than graphite-used VRFB in voltage and overall efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bipolar%20plate" title="bipolar plate">bipolar plate</a>, <a href="https://publications.waset.org/abstracts/search?q=DSA%20%28dimensionally%20stable%20anode%29" title=" DSA (dimensionally stable anode)"> DSA (dimensionally stable anode)</a>, <a href="https://publications.waset.org/abstracts/search?q=iridium%20oxide%20coating" title=" iridium oxide coating"> iridium oxide coating</a>, <a href="https://publications.waset.org/abstracts/search?q=TiO2%20nanotubes" title=" TiO2 nanotubes"> TiO2 nanotubes</a>, <a href="https://publications.waset.org/abstracts/search?q=VRFB%20%28vanadium%20redox%20flow%20battery%29" title=" VRFB (vanadium redox flow battery)"> VRFB (vanadium redox flow battery)</a> </p> <a href="https://publications.waset.org/abstracts/36558/dimensionally-stable-anode-as-a-bipolar-plate-for-vanadium-redox-flow-battery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36558.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">496</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">5351</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.

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">5348</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. Among various other components, such as the battery management system or the thermal management system, the battery system mostly consists of several cells which are integrated mechanically as well as electrically. Due to different vehicle concepts with regards to space, energy and power specifications, there is a variety of different battery systems. The corresponding assembly lines are specially designed for each battery concept. Minor changes to certain characteristics of the battery have a disproportionally high effect on the set-up effort in the form of high change-related costs. This paper will focus on battery systems which are made out of battery cells with a prismatic format. The product architecture and the assembly process will be analyzed in detail based on battery concepts of existing electric cars and key variety-causing drivers will be identified.

The most common effect of high penetration level of the renewables is the reverse power flow in the distribution feeders when the customers generate more power than their needs. The reverse power flow causes voltage rise and thermal issues in the power grids. To overcome the voltage rise issues in the distribution system, several techniques have been proposed including reducing transformers short circuit resistance and feeder impedance, installing autotransformers/voltage regulators along the line, absorbing the reactive power by distributed generators (DGs), and limiting the PV and battery sizes. In this study, we consider a medium-scale battery energy storage to manage the power energy and address the aforementioned issues on voltage deviation and power loss increase. We propose an optimization algorithm to find the optimum size and location for the battery. The optimization for the battery location and size is so that the battery maintains the feeder voltage deviation and power loss at a certain desired level. Moreover, the proposed optimization algorithm controls the charging/discharging profile of the battery to absorb the negative power flow from residential and commercial customers in the feeder during the peak time and sell the power back to the system during the off-peak time. The proposed battery regulates the voltage problem in the distribution system while it also can play frequency regulation role in islanded microgrids. This battery can be regulated and controlled by the utilities or a third-party ancillary service provider for the utilities to reduce the power system loss and regulate the distribution feeder voltage and frequency in standard level. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ancillary%20services" title="ancillary services">ancillary services</a>, <a href="https://publications.waset.org/abstracts/search?q=battery" title=" battery"> battery</a>, <a href="https://publications.waset.org/abstracts/search?q=distribution%20system%20and%20optimization" title=" distribution system and optimization"> distribution system and optimization</a> </p> <a href="https://publications.waset.org/abstracts/110651/voltage-and-frequency-regulation-using-the-third-party-mid-size-battery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110651.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">131</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">5346</span> Customized Cow’s Urine Battery Using MnO2 Depolarizer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raj%20Kumar%20Rajak">Raj Kumar Rajak</a>, <a href="https://publications.waset.org/abstracts/search?q=Bharat%20Mishra"> Bharat Mishra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bio-battery represents an entirely new long term, reasonable, reachable and ecofriendly approach to production of sustainable energy. 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">5345</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, 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">5341</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.

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">5339</span> Copper Oxide Doped Carbon Catalyst for Anodic Half-Cell of Vanadium Redox Flow Battery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Irshad%20U.%20Khan">Irshad U.

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">5337</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. Most of the study shows that there is an exponential increase in the quantity of lithium - ion battery energy storage system due to their power density, economical aspects and its performance.

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. The extended Kalman filter (EKF), the smooth variable structure filter (SVSF), and the time-varying smoothing boundary layer SVSF are applied on this model, and the results are compared. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=state%20of%20charge%20estimation" title="state of charge estimation">state of charge estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=battery%20modeling" title=" battery modeling"> battery modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=one-state%20hysteresis" title=" one-state hysteresis"> one-state hysteresis</a>, <a href="https://publications.waset.org/abstracts/search?q=filtering%20and%20estimation" title=" filtering and estimation"> filtering and estimation</a> </p> <a href="https://publications.waset.org/abstracts/68017/lithium-ion-battery-state-of-charge-estimation-using-one-state-hysteresis-model-with-nonlinear-estimation-strategies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68017.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">444</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">5335</span> Design of a Universal Wireless Battery Charger</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20B.%20Musamih">Ahmad B.

As the number of portable electronics devices increases, the demand for more flexible and reliable charging techniques is becoming more urgent. 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">5334</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">5330</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">5329</span> Evaluation of Electrophoretic and Electrospray Deposition Methods for Preparing Graphene and Activated Carbon Modified Nano-Fibre Electrodes for Hydrogen/Vanadium Flow Batteries and Supercapacitors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Barun%20Chakrabarti">Barun Chakrabarti</a>, <a href="https://publications.waset.org/abstracts/search?q=Evangelos%20Kalamaras"> Evangelos Kalamaras</a>, <a href="https://publications.waset.org/abstracts/search?q=Vladimir%20Yufit"> Vladimir Yufit</a>, <a href="https://publications.waset.org/abstracts/search?q=Xinhua%20Liu"> Xinhua Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Billy%20Wu"> Billy Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigel%20Brandon"> Nigel Brandon</a>, <a href="https://publications.waset.org/abstracts/search?q=C.%20T.%20John%20Low"> C. T. John Low</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, we perform electrophoretic deposition of activated carbon on a number of substrates to prepare symmetrical coin cells for supercapacitor applications. From several recipes that involve the evaluation of a few solvents such as isopropyl alcohol, N-Methyl-2-pyrrolidone (NMP), or acetone to binders such as polyvinylidene fluoride (PVDF) and charging agents such as magnesium chloride, we display a working means for achieving supercapacitors that can achieve 100 F/g in a consistent manner. We then adapt this EPD method to deposit reduced graphene oxide on SGL 10AA carbon paper to achieve cathodic materials for testing in a hydrogen/vanadium flow battery. In addition, a self-supported hierarchical carbon nano-fibre is prepared by means of electrospray deposition of an iron phthalocyanine solution onto a temporary substrate followed by carbonisation to remove heteroatoms. This process also induces a degree of nitrogen doping on the carbon nano-fibres (CNFs), which allows its catalytic performance to improve significantly as detailed in other publications. The CNFs are then used as catalysts by attaching them to graphite felt electrodes facing the membrane inside an all-vanadium flow battery (Scribner cell using serpentine flow distribution channels) and efficiencies as high as 60% is noted at high current densities of 150 mA/cm². About 20 charge and discharge cycling show that the CNF catalysts consistently perform better than pristine graphite felt electrodes. Following this, we also test the CNF as an electro-catalyst in the hydrogen/vanadium flow battery (cathodic side as mentioned briefly in the first paragraph) facing the membrane, based upon past studies from our group. Once again, we note consistently good efficiencies of 85% and above for CNF modified graphite felt electrodes in comparison to 60% for pristine felts at low current density of 50 mA/cm² (this reports 20 charge and discharge cycles of the battery). From this preliminary investigation, we conclude that the CNFs may be used as catalysts for other systems such as vanadium/manganese, manganese/manganese and manganese/hydrogen flow batteries in the future. We are generating data for such systems at present, and further publications are expected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title="electrospinning">electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20nano-fibres" title=" carbon nano-fibres"> carbon nano-fibres</a>, <a href="https://publications.waset.org/abstracts/search?q=all-vanadium%20redox%20flow%20battery" title=" all-vanadium redox flow battery"> all-vanadium redox flow battery</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen-vanadium%20fuel%20cell" title=" hydrogen-vanadium fuel cell"> hydrogen-vanadium fuel cell</a>, <a href="https://publications.waset.org/abstracts/search?q=electrocatalysis" title=" electrocatalysis"> electrocatalysis</a> </p> <a href="https://publications.waset.org/abstracts/124714/evaluation-of-electrophoretic-and-electrospray-deposition-methods-for-preparing-graphene-and-activated-carbon-modified-nano-fibre-electrodes-for-hydrogenvanadium-flow-batteries-and-supercapacitors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124714.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">291</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">5328</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 href="https://publications.waset.org/abstracts/search?q=battery%20grading%20algorithm" title="battery grading algorithm">battery grading algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=2nd-life%20repurposing%20battery%20system" title=" 2nd-life repurposing battery system"> 2nd-life repurposing battery system</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-analytic%20methodology" title=" semi-analytic methodology"> semi-analytic methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability%20and%20cyclability" title=" reliability and cyclability"> reliability and cyclability</a> </p> <a href="https://publications.waset.org/abstracts/136464/battery-grading-algorithm-in-2nd-life-repurposing-li-ion-battery-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136464.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">202</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">5327</span> Battery Replacement Strategy for Electric AGVs in an Automated Container Terminal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiheon%20Park">Jiheon Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Taekwang%20Kim"> Taekwang Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kwang%20Ryel%20Ryu"> Kwang Ryel Ryu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electric automated guided vehicles (AGVs) are becoming popular in many automated container terminals nowadays because they are pollution-free and environmentally friendly vehicles for transporting the containers within the terminal. Since efficient operation of AGVs is critical for the productivity of the container terminal, the replacement of batteries of the AGVs must be conducted in a strategic way to minimize undesirable transportation interruptions. While a too frequent replacement may lead to a loss of terminal productivity by delaying container deliveries, missing the right timing of battery replacement can result in a dead AGV that causes a severer productivity loss due to the extra efforts required to finish post treatment. In this paper, we propose a strategy for battery replacement based on a scoring function of multiple criteria taking into account the current battery level, the distances to different battery stations, and the progress of the terminal job operations. The strategy is optimized using a genetic algorithm with the objectives of minimizing the total time spent for battery replacement as well as maximizing the terminal productivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AGV%20operation" title="AGV operation">AGV operation</a>, <a href="https://publications.waset.org/abstracts/search?q=automated%20container%20terminal" title=" automated container terminal"> automated container terminal</a>, <a href="https://publications.waset.org/abstracts/search?q=battery%20replacement" title=" battery replacement"> battery replacement</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20AGV" title=" electric AGV"> electric AGV</a>, <a href="https://publications.waset.org/abstracts/search?q=strategy%20optimization" title=" strategy optimization"> strategy optimization</a> </p> <a href="https://publications.waset.org/abstracts/43477/battery-replacement-strategy-for-electric-agvs-in-an-automated-container-terminal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43477.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">388</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">5326</span> Study of Aging Behavior of Parallel-Series Connection Batteries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20Chao">David Chao</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Lai"> John Lai</a>, <a href="https://publications.waset.org/abstracts/search?q=Alvin%20Wu"> Alvin Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Carl%20Wang"> Carl Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For lithium-ion batteries with multiple cell configurations, some use scenarios can cause uneven aging effects to each cell within the battery because of uneven current distribution. Hence the focus of the study is to explore the aging effect(s) on batteries with different construction designs. In order to systematically study the influence of various factors in some key battery configurations, a detailed analysis of three key battery construction factors is conducted. And those key factors are (1) terminal position; (2) cell alignment matrix; and (3) interconnect resistance between cells. In this study, the 2S2P circuitry has been set as a model multi-cell battery to set up different battery samples, and the aging behavior is studied by a cycling test to analyze the current distribution and recoverable capacity. According to the outcome of aging tests, some key findings are: (I) different cells alignment matrices can have an impact on the cycle life of the battery; (II) symmetrical structure has been identified as a critical factor that can influence the battery cycle life, and unbalanced resistance can lead to inconsistent cell aging status; (III) the terminal position has been found to contribute to the uneven current distribution, that can cause an accelerated battery aging effect; and (IV) the internal connection resistance increase can actually result in cycle life increase; however, it is noteworthy that such increase in cycle life is accompanied by a decline in battery performance. In summary, the key findings from the study can help to identify the key aging factor of multi-cell batteries, and it can be useful to effectively improve the accuracy of battery capacity predictions.
