Abstract (en)
[origin: WO2011060818A1] The invention relates to a method for balancing the electrical voltages of at least two electrical accumulator units (102,106,110,114) that are connected in series. According to the invention, one accumulator unit (102, 110) is connected to the winding (120,136,156) of a coil (121) in order to excite said coil, and the other accumulator unit (102,106,114) is charged by means of said excited coil (121) by the subsequent connection of the winding (120,136,156) to said other accumulator unit. In addition, the invention relates to a corresponding electrical accumulator (101).
