Abstract
A thermal management system is provided that minimizes the effects of thermal runaway within a battery pack, the system using an integrated battery venting assembly comprised of an integrated exhaust port, a valve retention plate that covers the exhaust port and includes a plurality of retention plate ports, and a plurality of valves that are configured to seal the retention plate ports under normal conditions and unseal the retention plate ports during thermal runaway. As hot gas passes through the retention plate ports, the plate is configured to melt and be ejected, thereby allowing subsequent hot gas to pass through the larger exhaust port. A perforated cover plate may be used to protect the external surfaces of the retention plate and valves. An internally mounted exhaust guide may be used to direct the flow of hot gas expelled during the thermal runaway event.
