Abstract:
1. A battery cell module, comprising: a perimeter frame having a main body with a first opening formed in a first side of the main body and a second opening formed in a second side of the main body, the first side of the main body disposed opposite the second side of the main body, the main body having a first flange and a second flange, the first flange extending inwardly from the main body toward the first opening on the first side of the main body, and the second flange extending inwardly from the main body toward the second opening on the second side of the main body; a plurality of series-interconnected battery cells contained within the perimeter frame, a first end of the battery cells including a positive terminal end and a second end of the battery cells including a negative terminal end, the battery cells arranged into facing contact with each other, a first exterior face of one of the plurality of battery cells disposed adjacent the first opening, and a second exterior face of one of the plurality of battery cells disposed adjacent the second opening, the positive and negative terminal ends extending through the perimeter frame; and a first side cover disposed within the first opening of the perimeter frame and abutting the first exterior face of the battery cells, and a second side cover disposed within the second opening of the perimeter frame and abutting the second exterior face of the battery cells, the first side cover and the second side cover each being thermally conductive and each having a substantially flat inner surface and an outer perimeter, the outer perimeter of the first side cover deformed inwardly toward the second side and cooperating with the first flange to engage a first molded seal and the outer perimeter of the second side cover deformed inwardly toward the first side and cooperating with the second flange to engage a second molded seal, to form a fluid tight seal within the battery cell module and to retain the battery cells between the first side cover and the second side cover with a uniformly distributed compressive preload.
