초록

Energy storage batteries are currently composed of a large number of low-voltage battery cells. The state of charge of the cells is different due to the characteristic differences between cells. This causes some of the cells to be over-charged during charging and some of the cells to be over-discharging during discharging. To improve this phenomenon, this paper proposes a battery charger with an equalizing function that works during the charging and discharging processes. A performance comparison among the proposed charger and other similar topologies is carried out. The operational principle of the proposed strategy is analyzed and a control strategy with only a single voltage loop is proposed, which can guarantee two-stage charging. Experimental results show that the proposed charger can simultaneously achieve a high efficiency and the requirement of voltage equalization between cells.
