The battery system according to the invention comprises at least three battery cells connected in series, wherein a first battery cell is connected to a second battery cell and the second battery cell is connected to a third battery cell, at least one switching means, at least two rectifying means, which are designed to allow current flow in one direction only, and at least one energy storage means for temporarily storing stored energy in the battery system. The at least one energy storage means is designed to temporarily store energy stored in the second battery cell after the at least one switching means has been switched on. The at least two rectifying means are designed, after the at least one switching means has been switched off, to supply energy stored in the at least one energy storage means to the first battery cell when the ratio of the voltage of the first battery cell to the voltage of the third battery is lower than the ratio of the target voltage of the first battery cell to the target voltage of the third battery cell, and to supply energy stored in the at least one energy storage means to the third battery cell when the ratio of the voltage of the first battery cell to the voltage of the third battery cell is higher than the ratio of the target voltage of the first battery cell to the target voltage of the third battery cell. |
