Abstract
The battery has rod cells, which are arranged next to one another in multiple rows and the end-side electrical contacts of which are respectively electrically connected to one another in parallel and in series by a common contact plate. For effective cooling, a flat heat exchange pocket, through which a heat transfer medium flows, abuts against these contact plates. This heat exchange pocket consists of a multilayered thin film having an electrically insulating outer layer.
Claims21
A battery comprising rod cells, which are arranged next to one another in multiple rows, are electrically connected to one another in parallel and in series to form at least one cell block and are in thermally conducting contact with at least one cooling element, characterized in that end-side electrical contacts of a row of rod cells extending over a width of the battery are respectively electrically connected to one another in parallel by a common contact plate and these contact plates are in heat-conducting connection with a flat heat exchanger, which extends parallel to said plates, through which liquid flows and which consists of a film material forming a heat exchange pocket, there being provided parallel to the heat exchange pocket a pressure pocket, which is at least approximately of a corresponding size and is filled with a compressible medium.
