Electrochemical accumulator and vehicle comprising an electrochemical accumulator
First Claim
1. An electrochemical accumulator comprising:
- a plurality of electrochemical cells provided in a housing that includes;
a cooling air area for routing cooling air around an exterior surface of at least one of the cells; and
a degassing area for holding a gas which emerges from at least one of the cells in the event of a defect;
wherein the cooling air area and the degassing area are physically separated from one another in a gas-tight manner such that the cooling air and the gas may be passed out of the housing independently of one another; and
wherein the cooling air area comprises individual channels provided about the exterior surface of each of the cells;
wherein the individual channels are formed between webs.

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.

11. An electrochemical accumulator comprising:
-
a plurality of electrochemical cells provided within a housing, each of the electrochemical cells having a casing; a cooling air area comprising individual channels for passing cooling air around the casing of each of the cells; and a degassing area for holding a gas which emerges from at least one of the cells; wherein the cooling air area and the degassing area are physically separated from one another in a gas-tight manner such that the cooling air and the gas may be passed out of the housing independently of one another;
wherein the channels are formed by webs extending from a top portion of each of the cells to a bottom portion of each of the cells. - View Dependent Claims (12, 13, 14)

15. An electrochemical accumulator comprising:
-
a plurality of electrochemical cells provided within a housing; a cooling air area comprising individual channels for routing cooling air about an exterior surface of each of the cells; and a degassing area for receiving a gas which escapes from at least one of the cells; wherein the cooling air area is physically separated from the degassing area such that the cooling air and the gas may be passed out of the housing independently of one another;
wherein the channels are formed by webs extending from a top portion of each of the cells to a bottom portion of each of the cells. - View Dependent Claims (16, 17)
