Abstract: A rechargeable energy storage system includes a battery having a plurality of cells. The battery pack includes a first end, a second end, a first side, and a second side, an upper surface, and a lower surface. A battery support includes a support surface supporting the plurality of cells. The support surface has a first end portion, a second end portion, a first side portion and a second side portion. A ventilation member is arranged below the battery support between the first side portion and the second side. The ventilation member includes a surface section, and a plurality of wall members that project outwardly of the surface section. The plurality of wall members define a plurality of ventilation channels.

Abstract: An immersion cooling system for a battery system includes a battery enclosure and C metal-encased, pouch-type battery cells including C metal cases, C pouch-type battery cells arranged in the C metal cases, respectively, where C is an integer greater than one, and C vents on the C metal cases, respectively. A vent gas manifold is in fluid communication with the C vents of the C metal cases and is configured to remove vent gas passing through the C vents of the C metal cases from the battery enclosure.

Abstract: An immersion cooling system for a battery system includes a battery enclosure and G battery cell groups arranged in the battery enclosure. Each of the G battery cell groups include C battery cells, where G and C are integers greater than one. A plurality of dividers are arranged between each of the G battery cell groups. A gas manifold removes vent gases from each of the G battery cell groups.

Abstract: 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.
