ABSTRACT:
A capacity adjustment circuit provided in conjunction with each cell discharges the corresponding cell if the cell voltage is higher than a bypass operating voltage and, as a result, the extent of inconsistency among the voltages at the individual cells is minimized. A cell switching circuit switches the connections between the individual cells and the capacity adjustment circuits over predetermined time intervals.
