Beschreibung
Zusammenfassung:	A method for heating energy storage cells of an energy storage system configured to generate an n-phase supply voltage. The energy storage system including n energy supply branches connected in parallel. Each energy supply branch coupled between an output connection and an equipotential frame, and each of the energy supply branches including a plurality of series-connected energy storage modules. Each energy storage module including an energy storage cell module having at least one energy storage cell and a coupling device having coupling elements configured to selectively connect or bridge the energy storage cell module in a respective energy supply branch. The method includes connecting the output connections of the energy storage system to input connections of an n-phase electrical machine, and coupling the output connections via a neutral point of the electrical machine.
