A battery module is provided with a battery cell and a case. The case houses the battery cell. The case includes a first main face, a second main face, a first battery module coupling structure and a first elastically deforming structure. The first battery module coupling structure is arranged and configured to retain a first additional battery module over the first main face. The first elastically deforming structure is arranged and configured with respect to the first main face to elastically deform inward towards the second main face upon stacking the first additional battery module onto the first main face while the first additional battery module is retained to the first main face of the case by the first battery module coupling structure. |
