    • The invention relates to a method for controlling or regulating the voltage of individual cells (Z 1 ... Z N ) in a cell stack of an energy accumulator, especially an energy accumulator in a motor vehicle on-board supply system. Said method comprises the following steps: a) the cells (Z 1 ... Z N ) in the cell stack with the lowest charging state and optionally the highest charging state are determined; b) an intermediate accumulator (C, B) is connected in parallel with at least one cell (Z 1 ... Z N ) until the charging states of the relative cell(s) (Z 1 ,... Z N ) and the intermediate accumulator (C, B) have been aligned; c) the connection of the intermediate accumlator (C, B) and the relative cell(s) (Z 1 ... Z N ) is interrupted; d) the intermediate accumulator (C, B) is connected in parallel with the cells (Z 1 ... Z N ) with the lowest charging state, determined in a), until said cells and the intermediate accumulator are aligned in terms of the voltages thereof; e) steps a) to d) are carried out until the voltages of the individual cells (Z 1 ... Z N ) of the cell stack are aligned, with the exception of a pre-determined reliable difference between the open-circuit voltages.
