Electric vehicle battery pack protection system

摘要

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 each of the batteries and the lower battery pack enclosure panel, with a thermal insulator interposed between the conduits and the lower enclosure panel. A layer of thermally conductive material may be included which is interposed between the cooling conduits and the thermal insulator and in contact with a lower surface of each of the cooling conduits. 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.

主权项

1. A battery pack protection system, comprising:
a battery pack mounted under an electric vehicle, wherein said battery pack is configured to house a plurality of batteries; a plurality of deformable cooling conduits interposed between a lowermost surface of each of said plurality of batteries and an upper surface of a lower battery pack enclosure panel, wherein integral to each of said plurality of deformable cooling conduits is at least one coolant channel, and wherein said plurality of deformable cooling conduits are configured to deform and absorb impact energy when an object strikes a lower surface of said lower battery pack enclosure panel; and a thermal insulator interposed between said plurality of deformable cooling conduits and said upper surface of said lower battery pack enclosure panel.
