Patent ID: 7923144

Claim:
A battery pack system, said battery pack system comprising: a plurality of battery cells; a battery pack housing comprised of a first housing member and a second housing member piece complementary to said first housing member, wherein an internal region defined by a first housing member internal surface and a second housing member internal surface is configured to hold said plurality of battery cells, wherein said first housing member internal surface further comprises a first plurality of counterbores configured to hold a first end portion of said plurality of battery cells, wherein said first housing member internal surface further comprises a first plurality of orifices corresponding to said first plurality of counterbores and coupling said first housing member internal surface to a first housing member external surface, wherein said second housing member internal surface further comprises a second plurality of counterbores configured to hold a second end portion of said plurality of battery cells, wherein said second housing member internal surface further comprises a second plurality of orifices corresponding to said second plurality of counterbores and coupling said second housing member internal surface to a second housing member external surface; at least one first housing member collector plate arranged on said first housing member external surface, wherein said at least one first housing member collector plate further comprises a third plurality of orifices aligned with said first plurality of orifices, wherein said at least one first housing member collector plate is electrically conductive; at least one second housing member collector plate arranged on said second housing member external surface, wherein said at least one second housing member collector plate further comprises a fourth plurality of orifices aligned with said second plurality of orifices, wherein said at least one second housing member collector plate is electrically conductive; a first plurality of frangible conductors electrically connecting said at least one first housing member collector plate and each of said plurality of battery cells, wherein said first plurality of frangible conductors are electrically connected to each of said plurality of battery cells via a first terminal corresponding to each first end portion of said plurality of battery cells; and a second plurality of frangible conductors electrically connecting said at least one second housing member collector plate and each of said plurality of battery cells, wherein said second plurality of frangible conductors are electrically connected to each of said plurality of battery cells via a second terminal corresponding to each second end portion of said plurality of battery cells.
