NOVELTY - The battery (1) has a cooling device tempering battery cells (2) or frame flat cells i.e. lithium-ion-cells. Electrical components e.g. cell voltage monitoring elements and cell voltage balancing elements, monitor and/or control the battery function. A pressing plate (5) i.e. conductor board, presses the cells at a cooling plate (3). The plate comprises one of the components, and a cell group and the plate are pressed against each other by tensioning elements (8) i.e. tensioning belts, which comprise a tension spring (8.1) and elastic element. The elements are designed in a flexible manner.    USE - Battery for use in a motor vehicle e.g. hybrid vehicle and electrical vehicle (all claimed).    ADVANTAGE - The utilization of the cooling plate provides simple and cost-effective cooling of the battery cells. The pressing plate is simultaneously utilized for pressing the cooling plate at the battery cells and as a carrier for the electrical components of the battery by the integration of the electrical components of the battery in the pressing plate, thus saving installation space and manufacturing cost of the battery. The utilization of the tension spring and elastic element balances expansion of cells, which is caused by thermal influences or by inner pressure changes, without the voltages in the cell block exceeding critical values or loss of the pressing pressure of the cells. The tensioning elements are designed in a flexible manner, thus achieving secure connection of the battery with increased service life. The battery cells are pressed at the cooling plate with constant force, thus achieving good thermal contact between the battery cells and the cooling plate.    DETAILED DESCRIPTION - The cell voltage monitoring elements and cell voltage balancing elements are provided in form of micro-chips. The tensioning belts consist of metal or plastic.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic front view of a spring elastic tensioned cell block of frame flat cells.
