Patent ID: 8889283

Claim:
A modular frame for a battery module, the modular frame comprising: a floor; end walls that are perpendicular to the floor; side walls that are perpendicular to the floor and that are perpendicular to the end walls; substantially solid interior walls that extend between the end walls, that are perpendicular to the floor, and that are perpendicular to the end walls; a first space within the modular frame that is defined by the floor, the end walls, a first one of the side walls, and a first one of the interior walls and that is adapted to receive N prismatic cells of the battery module, wherein N is an integer greater than zero; a second space within the modular frame that is defined by the floor, the end walls, a second one of the side walls, and a second one of the interior walls and that is adapted to receive N other prismatic cells of the battery module, wherein the first and second ones of the side walls are different, and wherein the first and second ones of the interior walls are different; a chamber that is disposed between the interior walls; a first aperture to the chamber, wherein the first aperture is defined at least in part by the interior walls and the end walls; and a second aperture to the chamber, wherein the second aperture is formed through one of the end walls.
