A charge balancing system for a power battery includes a number of modules connected in series, each having two accumulator stages, each having an accumulator and isolated parallel converters connected to associated accumulator stages and to a low-voltage power system for supplying auxiliaries of an automobile. The converters have first unidirectional converters, each connected across terminals of a module and to the supply system, and second unidirectional converters each connected to the supply system and across the terminals of the accumulator stages, and a control unit for the first and second unidirectional converters. The control unit is configured for controlling a first converter to bring the modules to a similar charge level, for controlling a energy transfer from the battery to the supply system via the first converters, and for controlling a second converter to bring the associated accumulator stages of a module to a similar charge level.
