A battery module includes a plurality of battery cells, a cuboidal module housing, and, on a degassing side of the module housing, at least one module degassing opening. The battery module is connected to a temperature control system and the plurality of battery cells is directly surrounded by the flow of a temperature control fluid. A respective battery cell includes a cell degassing opening, wherein all cell degassing openings are arranged so as to point to the degassing side. The at least one module degassing opening and the respective cell degassing openings are directly connected to at least one degassing region. The at least one degassing region is delimited from the temperature control fluid. The at least one degassing region is smaller in its surface area extension than the degassing side, such that the temperature control fluid passes between the degassing side and the battery cells.
