Abstract: A structural battery pack includes a bottom cover, a bottom cell carrier, multiple battery cells, a cooling ribbon, a top cell carrier, and a top cover. The bottom cover has a rectangular shape that defines a longitudinal direction and a lateral direction. The bottom cell carrier is coupled to the bottom cover, and defines multiple bottom holders. The bottom holders are arranged in a hexagon pattern that defines multiple rows in the longitudinal direction and multiple columns in the lateral direction. The top cell carrier is coupled to the top cover, defines multiple top holders, and includes an interconnect board that interconnects the battery cells. The top holders are arranged in the hexagon pattern. The battery cells are installed in the bottom cell carrier and the top cell carrier. Each battery cell has a cylindrical shape. The cooling ribbon is installed between the battery cells along the rows.

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: Presented are battery assemblies with integrated fuel tanks, methods for making/using such battery assemblies, and fuel cell electric vehicles having rechargeable traction battery packs with integrated fiber-composite hydrogen fuel tanks. A rechargeable energy storage system (RESS) assembly includes a battery pack housing with an internal battery module compartment located between two tank mounting cavities. Each mounting cavity is recessed into a respective lateral side of the battery pack housing. Multiple rechargeable battery modules are electrically interconnected with one another and mounted inside the battery module compartment. Each battery module contains multiple battery cells, such as a stack of series-connected lithium-ion pouch cells. A fuel tank is mounted in each of the tank mounting cavities on the lateral sides of the battery pack housing. Each fuel tank, which may be fabricated from a carbon fiber reinforced polymer, stores and selectively dispenses a fuel, such as a hydrogen-rich, compressed gas fuel.

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.
