Abstract: A battery pack apparatus is disclosed that reduces the possibility of thermal runaway by improving the transfer of heat from the battery body and apparatus to the coolant by increasing the surface area of contact between the two. Principles of shape charge are used to drive debris, splinters and other particles towards the ground in an automobile in the event of an explosion, thereby reducing the possibility of harm to the driver, occupants and automobile. Fire retardant cartridges are suitably embedded to deter fire and incidental harm to person and automobile.
