摘要：

Charge equalization during the charging process has been extensively discussed for series-connected batteries. However, charge inequality may also happen to batteries during discharging. The imbalance among batteries may result over-discharging and consequently damage to the batteries. To solve the problem, a balanced discharging method for a series-connected battery bank is proposed. A flyback conversion circuit is designed with a pulse-width-modulation controller to achieve output voltage regulation as well as balanced discharging. The applicability of the proposed method is confirmed by experiments.
