1. A thermal management system for one or more components of a vehicle, comprising:
one or more heat generating components;
one or more compartments to contain the one or more heat generating components;
one or more vent openings disposed in the one or more compartments, each vent opening of the one or more vent openings closed by a thermally active material extending across the one or more vent openings, such that when exhaust gas from the one or more components interacts with the thermally active material to melt or dissipate the thermally active material, the one or more vent openings are opened allowing for removal of the exhaust gas from the one or more compartments; and
one or more vent manifolds disposed adjacent to the one or more vent openings, the one or more vent manifolds configured to direct the exhaust gas to ambient through one or more manifold openings in the one or more vent manifolds;
wherein the one or more heat generating components are one or more battery packs each including one or more pack vents through which exhaust gas is vented.
