Abstract

An apparatus for supplying power to a motor vehicle, in particular a passenger vehicle or motorcycle, has a plurality of electrochemical storage cells. At least one of the electrodes respectively situated in the storage cells is made of metal or is provided with a metal layer essentially over its entire surface. The metal electrode or the metal layer, in particular a metal foil, is connected in an electrically conductive manner via a connecting element to a terminal provided outside the storage cell. To provide a reliable apparatus for supplying power, in particular for the intermittent electric motor drive of a motor vehicle, a thermally conductive cooling plate, which is in thermal contact with essentially each of the terminals of the storage cells, is provided. The cooling plate dissipates the thermal energy which is supplied by the metal electrodes or the metal layers on the electrodes to the terminal via the connecting element.
