Battery pack venting system

A battery pack thermal management system, comprising:

• a sealed battery pack enclosure configured to hold a plurality of batteries, wherein said sealed battery pack enclosure is divided into a plurality of sealed battery pack compartments, and wherein said plurality of batteries are divided among said plurality of sealed battery pack compartments;
• a plurality of battery venting assemblies, wherein at least one of said plurality of battery venting assemblies is integrated into each of said plurality of sealed battery pack compartments, and wherein each of said plurality of battery venting assemblies is comprised of:
• an exhaust port integrated into an outer wall of said sealed battery pack compartment;
• and
• a valve, said valve configured to seal said exhaust port under normal operating conditions and unseal said exhaust port when at least one battery contained within said sealed battery pack compartment enters into thermal runaway,
• wherein each of said plurality of battery venting assemblies is further comprised of a valve retention carrier, wherein a first portion of said valve is comprised of an exhaust port sealing member, and wherein a second portion of said valve is comprised of a retention member configured to be captured by a valve retention aperture of said valve retention carrier.
