摘　　要：电动汽车的性能和成本很大程度上取决于动力电池组的性能和使用寿命,而电池组的性能和使用寿命又受到电池组均衡系统的影响。综述了电动汽车串联电池组的主要均衡方法,列举了国内外对于SOC预测和电压测量的常用手段,分析了国内外车用串联电池组电压均衡电路,并展望了其发展方向。Performance and cost of electric vehicles were depended largely on the performance and service life of the battery pack. Performance and service life of the battery pack were influenced by the balancing system of the battery pack. Electric vehicle series battery pack balancing method was summarized; the domestic and foreign common means for SOC estimation and voltage measurement were cited. Domestic and foreign car series battery voltage equalizer circuit was analyzed, and its development direction was prospected.
