摘要： This disclosure details exemplary traction battery pack designs for use in electrified vehicles. An exemplary traction battery pack may include a venting system having one or more vent exhaust channels. The vent exhaust channels may be integrated with an enclosure assembly of the battery pack for purging battery vent byproducts from the battery pack during cell venting events. In some embodiments, the vent exhaust channels are coated with a thermal protective coating for reducing heat dissipation to surrounding components.

摘要： Thermal barrier assemblies are provided for traction battery packs. An exemplary thermal barrier assembly may be configured to block or even prevent thermal energy associated with a battery thermal event from moving from cell-to-cell, compartment-to-compartment, and/or cell stack-to-cell stack within the traction battery pack. The thermal barrier assembly may include a locator configured to locate the thermal barrier assembly relative to a heat exchanger plate of the traction battery pack. The locator may at least partially fill and seal a slot formed in the heat exchanger plate.

摘要： Thermal barrier assemblies are provided for use within traction battery packs. An exemplary thermal barrier assembly may include features for establishing a sealed interface relative to one or more adjacent structures of a traction battery pack. In some implementations, the thermal barrier assembly may provide features for interfacing with cell stack cross-members beams, upper enclosure structures, lower enclosure structures, etc. The sealed interfaces substantially prevent thermal energy from moving from compartment-to-compartment/cell packet-to-cell packet during a battery thermal event.

摘要： Retention assemblies are disclosed for retaining a battery cell stack/matrix relative to an enclosure tray on traction battery packs that include cell-to-pack battery systems. The retention assemblies may be positioned between a cell stack/cell matrix and an interior surface of the enclosure tray. The retention assemblies may include features such as slider panels, clips, adhesive, and/or shims designed for holding the cell stacks down at the cell stack-to-enclosure tray interface.

摘要： A traction battery pack assembly includes first and second cell stacks each disposed along a cell stack axis and an enclosure assembly that encloses an interior area. The enclosure assembly has an enclosure structure that holds the first and second cell stacks within a cell-receiving area. The enclosure structure compresses the first cell stack along the cell stack axis of the first cell stack. The enclosure structure compresses the second cell stack along the cell stack axis of the second cell stack. The assembly further includes divider positioned between the first and second cell stacks. The divider partitions the interior area.
