Abstract: A battery mounting system for a vehicle including a mounting member configured to connect to an underbody. The mounting member includes a first end, a second end, a first side, and a second side. The second end is opposite to and spaced from the first end along a first axis and the second side is opposite to and spaced from the first side along a second axis that is orthogonal to the first axis. A cross-member extends between the first side and the second side. The cross-member forms a first battery module zone and a second battery module zone. The second battery module zone being spaced from the first battery module zone along the first axis. A first battery module is arranged in the first battery module zone below the vehicle underbody and a second battery module is arranged in the second battery module zone below the vehicle underbody.

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.

Abstract: A battery assembly includes a battery pan and battery cells. The battery cells are supported within the battery pan and disposed in a plurality of rows. The battery assembly includes a plurality of vents, and each of the plurality of vents is defined by a floor of the battery pan, support members, and a battery tray. Each vent extends a length of each row. An endcap is coupled to the structural plates of the battery pan. The endcap includes a plurality of apertures, a baffle, and a vent channel. The baffle has a baffle wall disposed opposite the plurality of apertures. The baffle wall extends to the ceiling and the floor of the elongated body. The vent channel extends along the baffle and is configured to carry vent gas. The battery assembly also includes a pack vent configured to exhaust the vent gas from the endcap.

Abstract: A prismatic cell cooling system includes a first prismatic cell having a first face, a second face angularly oriented to the first face and a third face oriented parallel to the first face and angularly oriented to the second face. A cooling jacket provides multiple coolant flow passages. A first cooling segment of the cooling jacket contacts one of the first face or the third face of the first prismatic cell. A second cooling segment of the cooling jacket directly contacts the second face of the first prismatic cell. The second cooling segment is contiguously and fluidly connected to the first cooling segment to promote simultaneous cooling of one of the first face or the third face and the second face of the first prismatic cell by flow of a coolant through the coolant flow passages.
