Original Abstract Submitted

Thermal mitigation techniques are provided that utilize coolant for mitigating or suppressing battery thermal events within traction battery packs. An exemplary battery array of a traction battery pack may include a heat exchanger plate having one or more holes sealed by a plug. The plugs may release coolant into a gas-tight chamber of the battery array during a battery thermal event. The coolant may flood the gas-tight compartment or may be directed as a pressurized coolant spray into the gas-tight compartment to mitigate the battery thermal event.
