Abstract: An energy storage unit has several storage elements (2, 2?) which are switched in series and a charge redistribution circuit (6, 6?). The latter is installed in such a manner that the voltage of the storage element (UELn, UEln?) is measured and compared with a voltage threshold value (UTHRn, UTHR, UTHRn?, UTHR?). When the threshold value is exceeded by a storage element, it removes charge from said storage element, thus reducing its voltage. According to one aspect, a storage-related temperature determination is conducted, and the threshold value is set variably in dependence on the determined temperature (Tn, T) in such a manner that it is reduced as the temperature increases. According to a further aspect, the threshold value is set variably in dependence on the current vehicle operating state, in such a manner that it is set higher for relatively brief periods of time when the storage or removal requirement is relatively high.

Abstract: A heat exchanger is connected to at least one energy storage cell of an energy storage device in a heat-conducting manner. The energy storage device is enclosed by a housing.
