Abstract: A grounding assembly for a battery enclosure includes a washer including a first serrated surface and a second serrated surface opposite the first serrated surface, a fastener including a serrated surface configured to mate with the second serrated surface of the washer, and a seal disposed on the washer. The first serrated surface is configured to remove a non-conductive coating from the battery enclosure. The seal is configured to form a watertight barrier between the washer and the battery enclosure.

Abstract: Traction battery pack designs 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. A peripheral component assembly may be secured within a wall of the outer enclosure assembly. The wall may be part of a tray or a cover of the outer enclosure assembly. The peripheral component assembly may include twist lock features for rotatably securing the peripheral component assembly in place within a mounting opening of the wall. Using the twist lock features, the peripheral component assembly may be installed from inside the outer enclosure assembly.

Abstract: An electrical ground assembly for a vehicle component includes a bushing including an upper serrated surface and a lower serrated surface opposite the upper serrated surface, a ground strap including a terminal, and a fastener including a head portion, a shaft extending from the head portion, and a flange extending radially between the head portion and the shaft portion. The terminal is electrically connected to the bushing between the upper serrated surface and the lower serrated surface. The flange includes a lower serrated surface configured to mate with the upper serrated surface of the bushing.

Abstract: A battery component includes a header body and a frame secured to the header body. The frame includes an electromagnetic shield portion. The electromagnetic shield portion defines at least one electrical connection port. The electrical connection port is configured to receive an electrically conductive object. The electromagnetic shield portion is configured to dissipate electromagnetic radiation from the electrically conductive object.

Abstract: An assembly includes a first piece of an enclosure having an interior area. The first piece has a first flange that projects outward from the interior area. The assembly also includes a second piece of the enclosure, the second piece including a second flange that projects outward from the interior area. The assembly further includes a gasket seal that is sandwiched between the first and second flanges. The first and second flanges are secured together at a flange-to-flange interface that is between the gasket seal and the interior area.

Abstract: An assembly includes a first piece and a second piece of an enclosure having an interior area. The first piece includes a first flange that projects outward from the interior area. The second piece includes a second flange that projects outward from the interior area. The assembly further includes a gasket seal and an intumescent. The gasket seal is sandwiched between the first and second flanges. The intumescent is sandwiched between the first and second flange at a position that is between the gasket seal and the interior area.

Abstract: Traction battery pack designs 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. A pressure equalization device may be disposed within a wall of the outer enclosure assembly and may be configured to both equalize the pressure inside the battery pack during normal battery operations and to prevent the unintended release of battery vent byproducts during battery thermal events.
