Hazard mitigation through gas flow communication between battery packs

Granted: January 17, 2017
Patent Number: 9548616
A system and method for mitigating the effects of a thermal event within a non-metal-air battery pack is provided in which the hot gas and material generated during the event is directed into the metal-air cells of a metal-air battery pack. The metal-air cells provide a large thermal mass for absorbing at least a portion of the thermal energy generated during the event before it is released to the ambient environment. As a result, the risks to vehicle passengers, bystanders, first…
