Abstract

A battery pack protection system is provided for use with an electric vehicle in which the battery pack is mounted under the car. The system utilizes a plurality of deformable cooling conduits located between the lower surface of the batteries within the battery pack and the lower battery pack enclosure panel. The cooling conduits are configured to deform and absorb impact energy when an object, such as road debris, strikes the lower surface of the lower battery pack enclosure panel. Further protection may be achieved by positioning a ballistic shield, alone or with a layer of compressible material, under the bottom surface of the battery pack.
