摘　　要：提出了一种动力电池组移位选通均衡充电系统,该系统为每节电池配备一个选通充电模块。电池管理系统通过控制选通充电模块,增大充电慢的电池的充电电流,加快其充电速度,实现动力电池组的均衡充电。选通充电模块采用移位选通的控制方式,使控制电路结构简单,便于扩展。实验表明,采用该系统,充电结束时电池端电压仅相差50 m V且没有过充电,达到电池组均衡充电的目的。This paper presents a shift gating equalization charging system for power battery pack. Each cell is equipped with a gating charging module in this system. In order to make an equalization charging for power battery pack, battery management system control gating charging module,increasing the charging current of the battery which is charging slowly,accelerating the charging speed. Gating charging module using the shift gating control mode, this control circuit structure is simple and easy to expand. Experiments show that using this system, when charging is completed the battery terminal voltage difference is only 50mV and no overcharging, the power battery pack achieving an equalization charging purposes.
