ABSTRACT:
A device and a method equalize a charge of series-connected individual cells of an energy accumulator with a DC/DC converter. The DC/DC converter draws energy from the energy accumulator or from another power source for charging an intermediate circuit capacitor whose voltage is inverted in a DC/AC converter and the alternating voltage is converted into an intermittent direct current by a rectifier via an AC bus and a coupling element. A switch is placed between the AC bus and each cell thereby enabling the cell to be coupled to the AC bus or disconnected therefrom.
