摘要： Thermal management and venting systems are provided for traction battery packs. An exemplary thermal management and venting system may include a vent manifold and a main coolant passage extending through the vent manifold. The vent manifold may be configured to expel a battery vent byproduct from the traction battery pack during a battery thermal event, and the main coolant passage may be configured to communicate a coolant for thermally managing a battery array of the traction battery pack. A heat exchanger of the thermal management and venting system may be configured to facilitate heat transfer between the battery vent byproduct and the coolant prior to expelling the battery vent byproduct from the traction battery pack.

摘要： A cooling system includes a plurality of heat exchanger assemblies corresponding to a plurality of battery packs and a fluid conveyance assembly. Each heat exchanger assembly includes a first heat exchanger inlet-outlet and a second heat exchanger inlet-outlet configured to receive a heat transfer fluid or discharge the heat transfer fluid. The fluid conveyance assembly is coupled to the heat exchanger assemblies and configured to circulate the heat transfer fluid in parallel to the heat exchanger assemblies in a U-flow scheme with an inlet and an outlet of the heat transfer fluid arranged at the same location. The fluid conveyance assembly includes a plurality of flow restrictors configured to balance the heat transfer fluid flowing into the heat exchanger assemblies.
