Assignee:

TESLA MOTORS, INC. - Palo Alto CA

International Classification:

H01M 2/12

US Classification:

429 53

Abstract:

A thermal management system is provided that minimizes the effects of thermal runaway within a battery pack. The system is comprised of a sealed battery pack enclosure configured to hold a plurality of batteries, where the battery pack enclosure is divided into a plurality of sealed battery pack compartments. The system also includes a plurality of battery venting assemblies, where at least one battery venting assembly is integrated into each of the sealed battery pack compartments, and where each of the battery venting assemblies includes an exhaust port integrated into an outer wall of the battery pack compartment and a valve, the valve being configured to seal the exhaust port under normal operating conditions and to unseal the exhaust port when at least one of the batteries within the battery pack compartment enters into thermal runaway.

International Classification:

H01M 10/50
H01M 2/12

US Classification:

429 53

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.
