This paper proposes a bridge switch topology for the equalization of DC uninterruptible power system storage battery, using LC equalizer to transfer energy from the cell with the highest state of charge(SOC) to that with the lowest SOC in the battery pack. The parameter design is presented. Avoiding the increase of the charge and discharge times of the battery brought by the roundabout equalization, the proposed strategy extends the working life of the battery and improves the efficiency of equalization and...

单个铅酸蓄电池标称电压为12 V,因此在实际中需要通过大量的单体电池串联使用来满足不同的电压需求[1-3]。而串联电池组中各单体电池之间荷电状态SOC(state of charge)或端电压不一致的情况普遍存在,因此采取有效的电池均衡具有极其重要的意义。根据存储和传输能量元件的不同,?
