Abstract:
1. A battery pack apparatus comprising a plurality of generally flat battery cells, a plurality of heat transfer jackets, each heat transfer jacket encasing at least one of the plurality of battery cells, the plurality of heat transfer jackets being arranged in spaced apart fact-to-face relation and being configured such that a plurality of generally parallel converging air flow spaces are defined between the spaced apart faces of adjacent heat transfer jackets, a top plate above the plurality of heat transfer jackets, a bottom plate beneath the plurality of heat transfer jackets, an air inlet duct covering a first side of the plurality of heat transfer jackets, the air inlet duct being shaped to define a converging air inlet plenum that becomes narrower in a direction from a first end of the battery pack apparatus toward a second end of the battery pack apparatus, and an air outlet duct covering a second side of the plurality of heat transfer jackets, the air outlet duct being shaped to define a diverging air outlet plenum that becomes wider in a direction from the first end of the battery pack apparatus toward the second end of the battery pack apparatus, wherein each of the air flow spaces is in air flow communication with the first and second plenums, wherein the air inlet and the air outlet are separate elements that are fastened to the top and bottom plates.
