Abstract (en)
[origin: WO2011060821A1] The invention relates to a method for balancing the electrical voltages of at least two electrical accumulator units (202, 206, 212, 218) that are connected in series. According to the invention, a coil (231, 259) is charged by means of one accumulator unit (202, 212) and the other accumulator unit (202, 206, 218) is charged with the energy of said charged coil (231, 259). Optionally, only the other accumulator unit (202, 206, 218) is charged. In addition, the invention relates to a corresponding electrical accumulator (201).
