Abstract
A method and a device for implementing a charge-state equalization among the cells of a vehicle battery are described. This charge-state equalization is carried out under the control of a vehicle-side control unit that includes the vehicle management and the vehicle control device. The charging currents required for the charge-state equalization are provided by a secondary battery of the vehicle and conveyed from there to the vehicle battery when the need for a charge-state equalization is detected.
