A method for the adjustment of states of charge of battery cells that are operated electrically in parallel connection, with the following steps: determination of the states of charge of the battery cells; selection of those battery cells whose states of charge are to be adjusted in accordance with a predeterminable selection rule; activation of those battery cells that are adjusted by means of a respective semiconductor switch of the battery cells, and deactivation of the remaining battery cells by means of the semiconductor switches of the respective remaining battery cells; carrying out the adjustment of the states of charge and monitoring of the states of charge; and termination of the adjustment of the states of charge when a predetermined state of charge has been attained by the activated battery cells.
