The partitioning region extends to a position between the first battery array and the second battery array. The partitioning region includes a foam core.

Abstract: A battery pack assembly includes a first battery array, a second battery array adjacent the first battery array, and a thermal barrier assembly that blocks transfer of thermal energy between the first battery array and the second battery array. The thermal barrier assembly having a sheet of material that is folded to provide a plurality of layers.

Abstract: A battery pack assembly includes battery cells, a thermal barrier adjacent the battery cells, and at least one scored region of the thermal barrier. The scored region is configured to rupture to provide a vent flap that opens to establish a vent path for gas expelled from at least one of the battery cells.

Abstract: A busbar assembly includes a busbar core configured to electrically couple a first component to a second component. The busbar core has a first connection portion that directly connects the busbar core to the first component, a second connection portion that directly connects the busbar core to the second component. A thermal barrier system covers the busbar core including the first connection portion, the second connection portion, or both.

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 and a lid. The lid is secured to the tray to provide an enclosure having an interior. At least one battery module is disposed within the interior. A cross-member is disposed within the interior adjacent to at least one battery module. A touch latch secures the tray or the lid to the cross-member.

Abstract: A battery pack mounting system includes, among other things, a bracket having a first connection flange configured to connect to a vehicle structure, a second connection flange configured to connect to a battery pack, and a spanner portion spanning from the first connection flange to the second connection flange. The bracket includes one or more openings that segment the bracket into at least a first section and a second section. Each of the openings extends into both the spanner portion and the first connection flange.

Abstract: A battery pack device includes a conduit compressing against a battery cell array. The conduit is to communicate fluid that is vented from an interior of a battery cell within the battery cell array along a non-linear vent path. The conduit can include an inlet that opens to a vent chamber of the battery cell array. The conduit can be a plate. A foot could extend from the conduit. The non-linear vent path could be a first vent path, and the foot could provide a portion of a second vent path.

Abstract: A sealing system includes an exterior plate, an interior plate, a first seal received against the exterior plate and configured to restrict moisture ingress through the exterior plate, and a second seal received against the interior plate and configured to restrict moisture ingress through the interior plate. The sealing system may be used to seal around tubing that extends through a vehicle battery enclosure.

Abstract: An assembly according to an exemplary aspect of the present disclosure includes, among other things, a top plate piece, a bottom plate piece and tubing sandwiched between the top plate piece and the bottom plate piece.

Abstract: A flex circuit system according to an exemplary aspect of the present disclosure includes, among other things, a substrate, at least one bus bar mounted to the substrate and at least one voltage sense lead integrated with the substrate.

Abstract: A battery cell spacer according to an exemplary aspect of the present disclosure includes, among other things, a body extending between a top surface and a bottom surface and a saddle disposed at the top surface of the body and configured to establish a barrier surface between metallic components.

Abstract: A vehicle traction battery assembly may include a traction battery and a battery tray. The traction battery is for powering a portion of an electrified vehicle. The battery tray is for supporting the traction battery and defines a coolant channel for distributing coolant in a first direction and a second direction. Battery cells of the traction battery are arranged with the battery tray such that the first direction and the second direction are oriented perpendicular relative to a longitudinal face of one of the battery cells. A plate may be secured to the battery tray without mechanical fasteners to retain coolant within the coolant channel. The plate may be made of aluminum and the battery tray may be die cast aluminum. An inlet channel may extend from an inlet to the coolant channel and may be disposed between a pair of openings defined by the battery tray.
