Abstract:
The invention provides a method for balancing the electrical voltages of at least two electrical accumulator units that are connected in series. According to the invention, one accumulator unit is connected to the winding of a coil in order to excite the coil, and the other accumulator unit is charged by the excited coil by the subsequent connection of the winding to the other accumulator unit. In addition, the invention provides a corresponding electrical accumulator.
