Abstract: A body structure for an automotive vehicle includes an enclosure for a power source, an upper shear structure assembly and a lower shear structure assembly. The enclosure includes a front cross-member, a rear cross-member, a left rocker and a right rocker. The upper and lower shear structure assemblies are disposed across the top and bottom of the enclosure, respectively, and are fastened to respective top and bottom surfaces of the cross-members and rockers. The upper and lower shear structure assemblies may include respective front and rear generally trapezoidal sections configured for attachment to respective front and rear box structures. Each of the shear structure assemblies is effective to dissipate in-plane a portion of an external load imposed upon the enclosure.

Abstract: Electric vehicle battery enclosures and methods of assembling electric vehicle battery enclosures involve a base portion to hold one or more batteries that provide motive power to an all-electric or hybrid electric vehicle. An electric vehicle battery enclosure includes a cover portion to mate with the base portion to enclose the one or more batteries, and a sealant to create a bond between the base portion and the cover portion around an entire perimeter of the enclosure and to seal the enclosure based on a uniform height of the sealant around the perimeter of the enclosure.

Abstract: A system for protecting a battery enclosure of a vehicle, comprising of a structural blocker configured to be fixedly attached to a side portion of the battery enclosure. The side portion faces a lateral direction, extending along a vehicle axis that extends between a front and a rear of a vehicle. The battery enclosure includes at least one cross member oriented along a lateral direction, wherein the structural blocker is configured to be aligned with an end of the cross member and localized to a region of the side portion proximate to the end of the cross member. The structural blocker is configured to transfer a side load from a structural component of the vehicle to the cross member.
