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: Exemplary traction battery pack designs for use in electrified vehicles may include a thermal insulating joint configured to isolate a heat transfer path at one or more structural connections between an enclosure tray and a battery internal structure (e.g., heat exchanger plate, cross member, etc.) of the traction battery pack. The thermal insulating joint may include a first thermal insulation component and a second thermal insulation component disposed on opposite sides of the battery internal structure. The thermal insulation components cooperate to block the heat transfer path across the structural connection, thereby insulating the battery internals from an ambient surrounding of the traction battery pack.

Abstract: A traction battery pack venting system includes a plurality of battery arrays within a traction battery pack. The battery arrays each have a plurality of individual battery cells. The system further includes a divider system that provides a plurality of vented gas receiving compartments. Each of the vented gas receiving compartments are separate and distinct from the other vented gas receiving compartments within the plurality of vented gas receiving compartments. Each of the vented gas receiving compartments are associated with one of the battery arrays. Each of the vented gas receiving compartments can be associated with a manifold. The vent gas produced from thermal runaway can be discharged to the vented gas receiving compartments, directed to a manifold, and discharge to the external atmosphere.

Abstract: A traction battery pack for an electrified vehicle may include a protection bracket for shielding a vent feature of the traction battery pack. An exemplary protection bracket may be made of a polymeric material and is designed to shield the vent feature from debris impingement. The protection bracket may include features such as a mesh venting pattern and a melting point that is lower than the temperature of battery vent byproducts that may be released during battery thermal events of the traction battery pack.

Abstract: Traction battery pack designs for use in electrified vehicles may include a vent management system adapted for managing battery cell vent byproducts during battery thermal events. The vent management system includes a multi-layered structure, with each layer of the structure having a unique function related to mitigating thermal propagation. The combined functions of the vent management system may include but are not limited to guiding vent byproducts along a desired path and direction, reducing the internal volume of the traction battery pack, and absorbing/trapping solid particles of the vent byproducts.
