break-word;">1，比亚迪是新能源汽车产业里全产业链自研的企业，最主要的诉求是在电动智能车领域里保持领先，战胜对手，电池只是它的基础，刀片电池确实基于整车系统优势思考优化的CTP方案。</span></p> <p style="margin: 15px 0px; padding: 0px; outline-width: 0px; max-width: 100%; clear: both;

break-word;">2，蜂巢能源是新进的动力电池主流企业，最主要的诉求是在动力电池市场中不被对手压制，技术自主可控，在生产便利性与装车实用性的同时与传统的MEB590模组有切换性，可以快速响应主机厂换代升级，在帮助客户成功的过程中成就自己。蜂巢短刀的CTP方案其实就是电池底箱有四个格栅，把短刀电池放入并连接即可。实现了新底盘设计与原有MEB底盘的完美兼顾，对快速发展长城汽车以外的客户特别有利。</span></p>

15px; text-align: justify; visibility: visible; box-sizing: border-box; overflow-wrap: break-word;">3，MEB模组是大众力推的标准模组或者电池标准品，主要诉求是大众给众多电池供应商一个标准指导，按大众的标准来做，可以进入大众的供应商体系，方便大众设计与供应链布局。</span></p> <p style="margin: 15px 0px; padding: 0px; outline-width: 0px; max-width: 100%; clear: both; min-height: 1em; color: #333333; font-family: -apple-system, BlinkMacSystemFont, 'Helvetica Neue', 'PingFang

15px; text-align: justify; visibility: visible; box-sizing: border-box; overflow-wrap: break-word;">目前可以初步判定：在磷酸铁锂或者将来的钠离子电池技术下，长薄型电池将成为主要发展方向，长度在600毫米以上到2.5米以内专利被比亚迪申请完成，300-600毫米间被蜂巢能源申请完成，各有各的主攻方向，各有各的主要诉求。</span></p> <section data-role="paragraph" style="margin: 0px; padding: 0px;
