Abstract
A thermal management system is provided that minimizes the effects of thermal runaway within a battery pack. The system includes a sealed battery pack enclosure configured to hold a plurality of batteries and at least one exhaust nozzle assembly. The exhaust nozzle assembly includes an exhaust nozzle that passes and directs the flow of hot gas from within the battery pack to the ambient environment during a thermal runaway event, a nozzle seal mounted within the exhaust nozzle that seals the exhaust nozzle during normal operation of the battery pack, and a nozzle seal mounting nut that holds the nozzle seal within the exhaust nozzle during normal operation and then melts during a thermal runaway event, thereby allowing the nozzle seal to be ejected through the exhaust nozzle during the event.
