ELECTROCHEMICAL ACCUMULATOR AND VEHICLE COMPRISING AN ELECTROCHEMICAL ACCUMULATOR

摘要

The invention relates to an electrochemical accumulator comprising a) a plurality of galvanic cells (2), b) a cover, c) a housing sealed by the cover, d) at least one connection pole for electrically contacting the accumulator (1) which is electrically connected to a group of the galvanic cells (2), e) an electrolyte in the housing, f) a cooling air space for receiving cooling air for cooling the cells (2), and g) a degassing space for receiving gas escaping from the cells (2) during a failure. According to the invention, the performance and safety are improved when h) the cooling air space and the degassing space are separated from each other in a gas-permeable manner, and i) the cooling air space and the degassing space are independently lead out of the housing.
