Abstract
A battery housing for a traction motor battery of a vehicle is disclosed that includes a plurality of elongated impact absorbing carbon fiber reinforced polymer members attached to the walls of the enclosure. The impact absorbing members may be corrugated members that have ridges and furrows connected by ramp surfaces that define trapezoidal spaces relative to the sides of the enclosure. The ridges are designed to be deformed into the trapezoidal space in the event of an impact to absorb impact forces and protect the battery. The impact absorbing members may be retained by T-shaped guides on the outer surface of the walls of the enclosure or may be adhesively attached to the sides of the enclosure.
