摘要

电动汽车用动力锂电池组一般采用多个电池单体串并联的结构,由于电池单体本身的不一致性,需要在电池组充、放电过程中进行能量的均衡控制。采用双层准谐振开关电容的均衡方法进行串联电池组的能量主动均衡,通过对常规双层开关电容均衡方法的改进,利用准谐振软开关实现开关的零电流导通和截止。仿真及实验结果验证了该方法的有效性。

Abstract：

Power lithium battery pack for electric vehicles usually use the structure of series battery string,since battery cells are not equal.So it is necessary for balance control during the battery charging and discharging process.A battery equalization method based on double-tiered quasi-resonant switched capacitor was presented in this paper,with the modification of the conventional double-tiered switched capacitor method,improved the use of quasi-resonant soft-switching to achieve zero-current switching on and off.The results of simulation and experimental verify the validity of the method.

Key words： Lithium battery active equalization switched capacitor quasi-resonant
