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 cell stack includes adjacent first and second battery cells respectively having a positive cell tab, a negative cell tab, and an outer surface. The outer surfaces are flush. The positive cell tab of the first battery cell protrudes from the outer surface of the first battery cell, and the negative cell tab of the second battery cell protrudes from the outer surface of the second battery cell. An isolative shield is positioned adjacent to the outer surfaces, and defines through-slots receiving therein a respective one of the cell tabs. A method includes providing the cell stack, inserting the cell tabs into the pair of through-slots of the isolative shield, positioning a primary surface of the isolative shield adjacent to the outer surfaces of the adjacent battery cells after inserting the cell tabs, and affixing the primary surface of the isolative shield to the cell stack.

Abstract: A multi-cell rechargeable energy storage system (RESS) includes an enclosure having a tray and a cover with battery cells mounted to the tray and a structural senseline assembly having a busbar subassembly for connecting the battery cells. The senseline assembly also includes a sensing device for detecting operation of the battery cell(s) and a sensing circuit connected to the busbar subassembly and to the sensing device for communicating electrical signals therefrom to an external controller. The senseline assembly additionally includes a first interconnect board (ICB) disposed between the battery cells and the busbar subassembly to position the sensing circuit, the busbar subassembly, and the sensing device, and electrically isolate the busbar subassembly from the cells. The senseline assembly further includes a second ICB disposed between the cover and the busbar subassembly and structurally connecting the cover to the first ICB to transmit physical forces between the cover and the tray.

Abstract: An interconnect board assembly includes a busbar assembly with at least one track having a plurality of busbars. The interconnect board assembly may be used with a power module having a plurality of battery cells. The interconnect board assembly includes a senseline assembly having a plurality of traces extending in proximity to the at least one track. An overmolded board frame is integrally formed over the busbar assembly and the senseline assembly. The overmolded board frame defines a first surface and a second surface. The overmolded board frame is configured such that a rigid load path is completed when the busbar assembly is joined to the senseline assembly and the plurality of battery cells.
