Abstract

A method for discharging a battery module, having at least two battery cells, of a battery having at least two battery modules, wherein the battery cells of each of the battery modules are arranged next to one another and are mechanically and electrically connected to one another, wherein, in each of the battery modules, the respective battery cells are individually activated and deactivated in terms of an energy storage function by a cell switch unit, wherein the battery cells of the battery module to be discharged are selectively electrically coupled successively to a discharge device by the cell switch unit and starting from one predefined battery cell, in order to individually successively electrically discharge the battery cells in order to discharge the battery module.
