Patent ID: 8703319

Claim:
An apparatus comprising: (a) a plurality of cuboidal battery cells; (b) a cooling system comprising a thermally conductive plate with channels for cooling fluid; (c) a battery housing comprising: (1) a first plurality of walls; (2) a second plurality of walls, wherein the second plurality of walls meets the first plurality of walls to form a housing comprising a grid with a first side located opposite to a second side, said grid outlining cuboidal spaces within, the housing further comprising a third side, a fourth side, a fifth side, and a sixth side, wherein the third side, the fourth side, the fifth side, and the sixth side form a border around the grid with the third side opposite the fifth side and the fourth side opposite the sixth side; (3) a plurality of channels formed by the first plurality of walls and the second plurality of walls, wherein the plurality of channels extends through the housing from the first side to the second side, the plurality of channels has a first plurality of openings on the first side, the plurality of channels has a second plurality of openings on the second side, (4) a first plurality of open chambers set on the outside face of the second side, wherein each open chamber is separated from an adjacent open chamber by the second plurality of walls and bordered by a first border in plane with the first side and a second border in plane with the second side, a third border in plane with the third side and a fourth border in plane with the fifth side: and (5) a second plurality of open chambers set on the outside face of the fourth side, wherein each open chamber is separated from an adjacent open chamber by the second plurality of walls and bordered by a fifth border in plane with the first side and a sixth border in plane with the second side, a seventh border in plane with the third side and an eighth border in plane with the fifth side, wherein each one of the plurality of batteries is located within one of the plurality of channels, the plurality of batteries are positioned so that each bottom of each battery of said plurality of batteries is in-plane with the second side of the battery housing and each said battery is directly in contact with the thermally conductive plate, and the battery housing covers only a portion of each side of each said battery.
