Apparatus for controlling the charging level of a bank of serially connected electrical cells and performing equalization of the charges in the battery array, comprising circuitry for alternately connecting a capacitor to pairs of adjacent battery cells by controlling switches at a predetermined switching frequency; circuitry adjusting the switching frequency to control the impedance of the equivalent resistance of transfer, such that the charging/discharging current is maintained within a range of desired values.
