Abstract

A power supply device for a hybrid or electric motor vehicle, in particular a passenger vehicle or a motorcycle, includes a plurality of electrochemical storage cells and/or double-layer capacitors. The electrochemical storage cells and/or double-layer capacitors have a casing surface and, in an axial direction, a base surface and a cover surface which are connected by the casing surface, and each include electrodes. Adjacent to the casing surface of at least one of the storage cells and/or double-layer capacitors, a heat-conducting cooling apparatus is disposed which, although electrically insulated from the at least one storage cell and/or double-layer capacitor, is in thermal contact with a first circumferential section of the casing surface and dissipates the heat energy introduced by the casing surfaces of the at least one storage cell and/or the double-layer capacitor.
