摘要：A device and a method for compensating charges of serially connected

individual cells of an energy storage device includes a DC/DC converter which taps powerfrom the energy storage device or an additional energy source, charges a capacitor of anintermediate circuit by way of the tapped power, inverts the voltage thereof in a DC/ACconverter, converts the alternating voltage into an intermittent direct current via an ACbus and a double capacitor by way of a rectifier, and charges the cell with theintermittent direct current at the lowest cell voltage.
