Abstract

An electrochemical accumulator includes a plurality of electrochemical cells, each of which has a casing. The accumulator also includes a cover, a housing which is closed by the cover, an electrolyte in the housing, and at least one connecting pole for making electrical contact with the accumulator, where the connecting pole is electrically connected to a group of the electrochemical cells. The accumulator also includes a cooling air area for holding cooling air for cooling the cells and a degassing area for holding a gas which emerges from the cells in the event of a defect. The cooling air area and the degassing area are separated from one another in a gas-tight manner and the cooling air area and the degassing area are passed out of the housing independently of one another. The cooling air area has channels which are guided on the casings of the cells outside the cells.
