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: Traction battery packs are disclosed for use in electrified vehicles. Exemplary traction battery packs may include an outer enclosure assembly establishing an interior, and a battery array housed within the interior. The outer enclosure assembly includes a multi-layered enclosure cover designed to withstand the high temperature environment of the traction battery pack while also providing weight savings. In some embodiments, the multi-layered enclosure cover is a roll-bonded structure that includes an inner layer, an outer layer, and a mid-layer. The various layers of the roll-bonded structure may be constructed out of various materials.

Abstract: A traction battery pack assembly includes, among other things, first and second pieces of an enclosure having an interior area. An attachment rim is disposed at a periphery of the first piece. The attachment rim has a stand-off that includes a platform portion and turned flange. The platform portion extends outward from the interior area in a first direction. The platform portion provides an aperture. The turned flange extends away from the platform portion in a second direction and terminates at an end face. The second direction is transverse to the first direction. The aperture is configured to receive a fastener that clamps the end face against the second piece.
