BATTERY ENCLOSURE WITH AIR FLOW CHANNEL FOR COOLING DURING THERMAL PROPAGATION

A system includes a prismatic battery assembly including an enclosure, an air flow inlet, an air flow outlet, an air flow channel, and a vent channel. The enclosure has a first end, a second end, a first side wall, and a second side wall. The air flow inlet is disposed at the first side wall, and the air flow outlet is disposed at the second side wall. The air flow channel extends within the enclosure between the air flow inlet and the air flow outlet. The vent channel has a gas vent inlet that is fluidically connected to the air flow channel. The system also includes an air flow source configured to direct air flow from the air flow inlet along the air flow channel and out the air flow outlet. The air flow draws heated vent gasses away from the prismatic battery assembly.
