Abstract: A traction battery assembly according to an exemplary aspect of the present disclosure includes, among other things, a tray, at least one battery module, a lid secured to the tray to provide an enclosure having an interior that houses the at least one battery module, the lid having a lid aperture, and a reinforcement member is secured directly to the lid. The reinforcement member has a reinforcement member aperture. A fastener extends through the lid aperture and the reinforcement member aperture. The fastener is secured to a structure within the interior. The reinforcement member is secured directly to the lid separately from the fastener.

Abstract: A battery pack assembly includes, among other things, a tray, a lid secured to the tray to provide an enclosure having an interior, at least one battery module disposed within the interior, a cross-member disposed within the interior adjacent to the at least one battery module, and a stanchion secured to the cross-member. The stanchion disposed entirely within the interior. The assembly further includes a fastener that extends through an opening in the lid to engage the stanchion.

Abstract: A rocker including a sill elongated along an axis and a reinforcement disposed in the sill. The reinforcement, in cross-section transverse to the axis, includes an intermediate portion, a first lobe, and a second lobe. The first lobe has a first wall extending from the intermediate portion to a first end. The second lobe has a second wall extending from the intermediate portion to the second end. The first and second ends abut opposite surfaces of the intermediate portion. The first lobe and the second lobe of the reinforcement resist buckling in response to components of the impact force applied to the sill reinforcement.

Abstract: A side impact protective structure is provided for a vehicle floor pan. Right and left rear rails are attached, respectively, to right and left lateral sides of the floor pan. A kick-up cross member extends transversely between the right and left rocker assemblies. A right reinforcement is welded to the floor pan, the right rear rail, and the kick-up cross member. A left reinforcement is welded to the left rear rail, to the floor pan and the kick-up cross member. An assembly method includes the steps of selecting a thin mild steel floor pan between a thicker HSLA steel structural member and a thicker corner reinforcement and welding the components together with three thickness welds.

Abstract: A vehicle body structure includes a side sill formed of high strength steel and a seat cross-member formed of high strength steel. A floor pan is welded to at least one of the side sill and the seat cross-member. A flange includes a base extending from the seat cross-member and a tab extending from the base. The tab is spaced from the seat cross-member and is welded to the floor pan and the side sill.
