Charge equalization circuit for discharging series-connected batteries with regulated output

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 in over-discharging and consequently damage to the batteries. To solve t...

Description
Summary: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 in 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.
