Abstract
A method for balancing the electrical group voltages of at least two accumulator groups which are connected in series and each of which have a plurality of accumulator units provides that one accumulator group is connected to the winding of a coil in order to excite the coil, and the other accumulator group is charged by the excited coil by the subsequent connection of the winding to the other accumulator group. In addition, a corresponding electrical accumulator is provided.

A method for balancing the electrical group voltages of at least two serially connected electrical accumulator groups, each accumulator group having a plurality of accumulator units, comprising the steps of:
- connecting a first accumulator group to the winding of a coil for its excitation;
- and after that, by means of the excited coil, charging a second accumulator group by connection of the winding to the second accumulator group.
