摘要:

随着电动汽车动力电池的第一个退役高峰期的来临,废旧动力电池的后续处理对环境和社会资源提出严峻挑战,储能电站是退役动力电池梯次利用的有效途径,研究退役动力电池梯次利用关键技术及其发展现状具有重大现实意义。针对梯次利用电池面临的主要问题及技术难点,首先详细介绍了国内外一些梯次储能示范工程,总结梳理了当前行业内存在的相关政策与标准。在此基础上,对退役电池梯次利用过程中的电池分类筛选、重组、热失控特征、均衡控制及电极材料回收等关键技术展开研究,并着重分析不同方法及控制策略的优缺点。最后结合国内外电动汽车发展趋势,对梯次利用电池的商业应用模式进行探讨与展望。

Abstract:

With the advent of the first retirement peak period of electric vehicle power battery, the subsequent treatment of used power battery is posing a serious challenge to the environment and social resources. The energy storage power station is an effective way for cascaded utilization of decommissioned power battery. It is of great practical significance to study the key technology and development status of decommissioned power battery cascaded utilization. In view of the main problems and technical difficulties faced by the battery cascaded utilization, this paper firstly introduces some echelon energy storage demonstration projects at home and abroad, and summarizes and combs the relevant policies and standards in the current industry. On this basis, the key technologies of battery classification, screening, reorganization, characteristics of the thermal runaway, equalization control and electrode material recovery in the process of cascaded utilization are studied, and the advantages and disadvantages of different methods and control strategies are emphatically analyzed. Finally, combining with the development trend of electric vehicles in China, the commercial application mode of battery cascaded utilization is discussed and prospected.
