This disclosure details exemplary traction battery pack venting systems for use in electrified vehicles. An exemplary traction battery pack system may include a venting system having one or more vent ducts for expelling battery vent byproducts from a battery pack. The vent ducts may include a thermal barrier configured to block heat emitted by the battery vent byproducts during cell venting events. In some embodiments, the thermal barrier includes a thermal barrier coating. In other embodiments, the thermal barrier includes both a thermal barrier coating and a thermal barrier layer. In still other embodiments, a second thermal barrier may be applied to vehicle components located near the battery pack for improving the thermal barrier properties.

Thermal barriers for traction battery pack venting systems and nearby vehicle components

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.

Traction battery securing assembly and method

An exemplary traction battery assembly includes, among other things, a battery pack and a securing assembly. The securing assembly secures the battery pack to a structure of the vehicle. The securing assembly is disposed along a horizontally facing side of the battery pack and is configured to move from a first position to a second position in response to a load to permit movement of the battery pack relative to the vehicle structure.

An exemplary battery assembly includes an endwall, an endplate, and a flange secured within a recess to secure the endwall relative to the endplate. One of the endwall or the endplate provides the flange, and the other of the endwall or the endplate provides the recess.

Battery pack array retention

An exemplary method includes, among other things, providing first and second blanks that are nominally identical and that include an array of raised features. The method further includes removing a first combination of individual raised features from the first blank to provide a first battery component with a first flow path, and removing a different, second combination of individual raised features from the second blank to provide a second battery component with a different, second flow path. An exemplary battery assembly includes, among other things, a blank having a plurality of ribs extending from a floor. The blank is configured such that a first combination of the ribs are removable from the blank to provide a first battery component having first flow path, and a different, second combination of the ribs are removable from the blank to provide a second battery component having a different, second flow path.

Battery component with a flow path

An exemplary battery assembly includes an endplate of a battery array, and an enclosure wall secured directly to the endplate from outside an open area of a battery pack enclosure. An exemplary method of securing a battery array includes positioning a battery array within an open area of an enclosure and, from a position outside the open area, securing an endplate of a battery array directly to a wall of a battery pack enclosure.
