In a method for determining the state of charge of an electrical accumulator, individual cell voltages are recorded, and the highest and/or the lowest individual cell voltage is ascertained. A present maximum charge and/or a present minimum charge of the appertaining accumulator cell is determined using a characteristic curve and the highest and/or the lowest individual cell voltage.
