The invention relates to a battery degassing unit for a battery housing, comprising a main body which can be connected in a fluid-tight manner to the edge of a pressure-equalizing opening of the battery housing and which has at least one gas passage, the gas passage opening is covered on the inner side by a first filter having a plurality of first grid openings and by a second filter arranged on the side opposite the inner side of the first filter and having a plurality of second grid openings. And at least one of the filters is completely lapped with the gas through hole. The base body is provided with at least one fixing device acting area, and the fixing device acting area is used for fixing the battery degassing unit and a battery shell together. At least one of the two filters is designed in a wave-like manner such that the longitudinal extent in the stretched state is at least 1.3 times the longitudinal extent in the wave-like state in at least one direction. 本发明涉及一种用于电池壳体的电池除气单元，具有能够与电池壳体的压力平衡开口的边缘流体密封
