A thermal management system for one or more components of a vehicle includes one or more heat generating components, and one or more compartments to contain the one or more heat generating components. One or more vent openings are located in the one or more compartments. Each vent opening of the one or more vent openings are closed by a thermally active material, such that when exhaust gas from the one or more components interacts with the thermally active material, the one or more vent openings are opened allowing for removal of the exhaust gas from the compartment. One or more vent manifolds are located adjacent to the one or more vent openings. The one or more vent manifolds are configured to direct the exhaust gas to ambient through one or more manifold openings in the one or more vent manifolds.
