1. A battery module assembly comprising:
a battery module having a shape of a generally rectangular solid and formed by stacking plural rectangular battery cells; at least four plates covering the battery module from four directions, the plates including: a pair of side plates arranged along two side wall faces, opposing to each other in a stacking direction of the battery cells, of the battery module; a lower plate that swingably supports one end of the pair of side plates by a pair of hinge mechanisms located on corners of the battery module and that is arranged along a lower wall face of the battery module; and an upper plate that is arranged along an upper wall face of the battery module so as to be opposite to the lower plate, and that connects the other ends of the pair of side plates to each other, wherein the side plates and the upper plate are tightened and fixed by use of a fastening member with pressure being applied in the stacking direction of the battery cells in order to fix the battery module, wherein a seat for supporting an electrode plate serving as an output terminal of the battery module is arranged on a surface of the upper plate, wherein the battery module has a structure in which the battery cells and separators, which are arranged to secure a predetermined gap between the battery cells, are alternately stacked, each separator defining a frame adapted to receive therein adjacent battery cells, wherein the adjacent battery cells inserted into the separator together with the separator form a cooling air passage, wherein each of the separators includes a top plate and a bottom plate coupled to the top plate by a pair of side separator plates, and a partition bar spaced from each of the side separator plates and spanning between the top and bottom plates, the separators are formed with positioning projections received in positioning holes formed respectively in the upper plate and the lower plate. |
