Summary:A method for determining a respective state of each of a plurality of cells of a battery, comprising at least the following steps: a) carrying out a charging operation or a discharging operation on the cells; b) determining a discharge voltage of each of the cells and a charge voltage of each of the cells; c) determining at least one state parameter for each cell, wherein the state parameter is derived from the discharge voltage and the charge voltage, wherein a discharge voltage and a charge voltage of at least one other cell is taken into account for the state parameter.
