摘要： 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.

摘要： 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.

摘要： A terminal arrangement for high-voltage batteries is disclosed. The terminal arrangement includes a substrate having concentric generally tubular inner and outer walls extending from an upper surface of the substrate, with an annular terminal disposed on the upper surface between the inner and outer walls. The inner and outer walls have respective inner and outer heights above a top surface of the annular terminal and the annular terminal has a radial span between the inner and outer walls, wherein the inner and outer heights and the radial span are sized so as to preclude human fingertips above a predetermined size from touching the annular terminal.

摘要： A two-piece current collector sub-assembly includes a current collector bridge disposed on the positive terminal of a first battery cell and a current collector plate disposed on a second battery cell. The current collector plate surrounds a positive terminal of the second battery cell. The current collector bridge is coupled to the current collector plate to electrically connect the first battery cell to the second battery cell.

摘要： Presented are electrical interconnect board (ICB) assemblies with multilayer current collectors, methods for making/using such ICB assemblies, battery systems employing such ICB assemblies, and vehicles equipped with such ICB assemblies. An ICB assembly includes an electrically insulative ICB board frame that mounts to a battery case, an electrically conductive busbar assembly mounted to the board frame, and one or more end terminal assemblies mounted to the board frame adjacent opposing ends of the busbar assembly. The busbar assembly includes one or more busbar tracks that electrically interconnect a group of battery cells. Each end terminal assembly includes a bottom current collector plate that attaches to the ICB board frame and electrically connects to the battery cells and busbar track, a dielectric separator attached to the bottom current collector plate, and a top current collector plate attached to the dielectric separator and electrically connected to the bottom current collector plate.

摘要： A multi-cell rechargeable energy storage system has battery cells disposed in an enclosure, and arranged in cell modules. Collectors are arranged to electrically connect the battery cells arranged in the cell modules. An electric power bus is arranged in a spine, and terminates at positive and negative terminals. First busbars, a second busbar, and end collectors electrically connect the cell modules in series between the positive terminal and the second terminal. Cell monitoring controllers are arranged to monitor the cell modules. A potting compound is arranged to encapsulate only an upper portion of the battery cells. A thermal management system including first and second fluidic manifolds are fluidly coupled to longitudinal heat exchange plates to thermally couple to the battery cells.
