Abstract
A tunnel structure in an electric vehicle for providing a protected battery storage location and for increasing the stiffness of a vehicle's body structure. The tunnel structure may include a floor portion coupled to the floor of the vehicle, a front portion coupled to the vehicle firewall, and a paneled portion extending between the front portion and the floor portion. The tunnel structure may also include a plurality of panels and ridges that extend from the front portion toward a rear edge of the floor portion. The specific arrangement of the panels and ridges can improve the transfer of energy in the event of a collision.
