Abstract (en)
[origin: WO2007147660A1] The energy required for equilibrating the charges with at least two cells (Z) in series in an energy store (DLC) is introduced by means of a first charging path (2, 4, C<SUB>K</SUB>) via an alternating voltage bus (4) to that cell (Z<SUB>X</SUB>) with the lowest cell voltage (U<SUB>ZX</SUB>). The alternating voltage bus (4) is supplied with power from an energy store (B, DLC) by means of a DC converter (1) and an AC converter (2). According to the invention, a second charging path (D<SUB>L</SUB>) is provided, which can alternatively connect the DC converter (1) connector which is connected to the AC converter (2), to a series circuit of several cells (Z), in particular, all cells (Z) of the energy store (DLC).
