Abstract: An electric-powered vehicle or a vehicle converted from internal combustion power to electrical power is provided having increased crashworthiness. The present invention provides crash energy management structures for such vehicles to achieve the increased crashworthiness. Because of the additional mass added to such vehicles by an energy source containment unit and the associated batteries, the crash energy management structure functions either to prevent an energy source containment unit from moving forward as a result of a collision or to enhance the strength of the crumple zone, or both, whether the vehicle is of monocoque construction, frame construction, or some combination thereof.
