Abstract

A motor vehicle includes a traction battery module which has a hermetically sealed module housing in which at least one cell stack pair including a left-hand-side and a right-hand-side cell stack including, in each case, at least two battery cells is accommodated. The traction battery module is arranged in the vehicle floor and extends symmetrically in relation to the vehicle center (M) in the vehicle transverse direction (X). The traction battery module has a bottom wall in a horizontal plane. A gas space is formed in the module housing in the vehicle center (M) and between the left-hand-side cell stack and the right-hand-side cell stack with respect to the vehicle transverse direction (X). The module bottom wall has a degassing element centrally in the vehicle in the region of the gas space.
