Battery module
First Claim
1. A battery module comprising:
- a battery cell; and
a case housing the battery cell, the case including 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 being arranged and configured to retain a first additional battery module over the first main face,the first elastically deforming structure being 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.

Abstract
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.

12. A battery assembly comprising:
-
a first battery module including a first case housing a first battery cell, with the first case including a first main face and a second main face; and a second battery module including a second case housing a second battery cell, the second case including a first main face and a second main face, the first and second battery modules being stacked in a battery module stacking direction, with the first main face of the first battery module face overlying the second main face of the second battery module, each of the first and second cases include, a first battery module coupling structure, a second battery module coupling structure, a first elastically deforming structure, and a second elastically deforming structure, the first battery module coupling structure of the first battery module engaged with the second battery module coupling structure of the second battery module such that the first and second battery modules are retained together with the second main face of the second battery module over the first main face of the first battery module, the first elastically deforming structure of the first battery module and the second elastically deforming structure of the second battery module contacting each other and elastically deforming in the battery module stacking direction towards the first and second battery cells, respectively.
