Apparatus for supplying power to a motor vehicle

摘要

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.

1. An apparatus for supplying power to a motor vehicle, comprising:
a plurality of storage units having electrodes, at least one of the electrodes in the storage units each having a metallic construction; a plurality of terminals arranged on a side of and outside of the storage units, a respective metallic electrode being connected in an electrically conductive manner to a respective terminal with a connecting element, wherein the plurality of terminals are electrically connected via electrical connectors such that the plurality of storage cells are connected in series; a thermally conductive cooling plate having a plurality of cooling channels through or around which a heat-dissipating medium flows, said cooling plate further having a plurality of thermally conductive spring elements thermally contacting the plurality of terminals and dissipating thermal energy supplied by the electrodes to the terminals via the connecting element; and an electrically insulating, thermally conductive layer that is layered in a plane separate from a plane of the cooling plate and is in physical contact with the cooling plate, wherein the thermally conductive layer further is between the plane of the cooling plate and the plurality of terminals thereby electrically insulating the cooling plate from the plurality of terminals, and wherein the thermally conductive layer extends across and is in physical contact with a top of the plurality of terminals via an adhesive layer.
