摘要
为了解决电动汽车锂离子动力电池组中单体电池间存在的不一致性问题,提出一种复合均衡方法。首先,分别对基于附加电池的主动均衡与电阻式被动均衡进行建模仿真分析,揭示这两种均衡的特点。在此基础上提出了一种将主动均衡与被动均衡相结合的复合均衡方法,根据电池组不同的状态,选择相应的均衡模式。仿真结果表明,复合均衡方法能够结合不同均衡方法的优势,达到更好的均衡效果,提高了均衡效率。
In order to solve the inconsistency problems among cells in lithium-ion power battery packs of electric vehicles （EVs）, a composite equalization method is proposed. Firstly, modeling and simulation analysis of both active equalization based on an additional cell and resistance-type passive equalization are carried out respectively, and the characteristics of these two equalization methods are revealed. On this basis, a composite equalization method combining active and passive equalization is proposed, and the corresponding equalization mode can be selected according to different states of battery packs. The simulation results show that the composite equalization method can achieve better equalization results through combining the advantages of different equalization methods, improving the equalization efficiency.
