Beschreibung
Zusammenfassung:	An energy storage device for a motor vehicle includes a first energy store and a second energy store for storing electrical energy, a charging connection for charging the energy stores, an operating connection for operating a load on the energy storage device, and a switching device which has a plurality of switching elements and via which the energy stores can be connected selectively in series or in parallel. A fifth switching element of the switching device is permanently electrically coupled to the electrical poles of opposite polarity of the energy stores and the energy stores can be connected in series via the fifth switching element independently of the other switching elements of the switching device.
