Battery Pack Gas Exhaust System
First Claim
1. A battery pack thermal management system, comprising:
- a multi-sided, substantially airtight battery pack enclosure configured to hold a plurality of batteries, wherein at least one side member of said battery pack enclosure includes at least one cavity, wherein an inner enclosure wall of said at least one side member includes a plurality of perforations, said perforations configured to pass gas from within said battery pack enclosure to said at least one cavity of said at least one side; and
at least one gas exhaust port integrated into an outer wall of said battery pack enclosure, wherein said at least one gas exhaust port is in gaseous communication with said at least one cavity of said at least one side member, and wherein said at least one gas exhaust port is configured to pass gas from within said at least one cavity to an ambient environment external to said battery pack enclosure when at least one battery of said plurality of batteries enters into thermal runaway.

Abstract
A thermal management system is provided that minimizes the effects of thermal runaway within a battery pack. The system is comprised of a multi-sided, substantially airtight battery pack enclosure configured to hold a plurality of batteries, where at least one side of the battery pack enclosure includes at least one cavity. An inner wall of the enclosure includes a plurality of perforations configured to pass gas from within the enclosure to the cavity within the at least one side member. The system is further comprised of at least one gas exhaust port integrated into an outer wall of the enclosure and configured to pass gas from within the cavity of the enclosure side member to the ambient environment when one or more batteries contained within the battery pack undergo thermal runaway.
