A device for balancing an energy accumulator, especially an energy accumulator in an on-board power supply system of a motor vehicle, is provided. The energy accumulator is formed by a cell assembly of a serial connection of a plurality of cell groups, respective balancing circuits being connected to voltage connections of respective cell groups and comprising a discharge resistor. The discharge resistor of a respective balancing circuit has a temperature-dependent resistance characteristic, and the discharge resistors of at least some of the balancing circuits are thermally intercoupled.
