1. A battery module comprising:
a battery cell stack which includes battery cells,
a deformable foam plate that is arranged between the battery cells, wherein the deformable foam plate is configured to compensate for deformations of the battery cells during their charging and discharging or on account of aging of the battery cells,
a cooling medium passageway extending between the battery cells through which a cooling medium is conducted between the battery cells in order to cool the battery cells, wherein the cooling medium is a cooling liquid which makes direct contact with the battery cells via the cooling medium passageway, and
a cooling structure for conducting the cooling liquid to one of the battery cells and along said one of the battery cells, the cooling structure being arranged between said one of the battery cells and the deformable foam plate,
wherein said deformable foam plate contacts said cooling structure, and the cooling structure makes contact with said one of the battery cells,
wherein the cooling structure comprises a first cooling plate on a side of the cooling structure which faces said one of the battery cells, which first cooling plate bears against said one of the battery cells, said first cooling plate having passages for the cooling liquid,
wherein said cooling structure has a second cooling plate on a side of the cooling structure which faces away from said one of the battery cells, which second cooling plate bears against the deformable foam plate.
