Abstract: A system includes a battery pack having a first sub-pack and a second sub-pack, the first sub-pack having a first cell group and a second cell group, and the second sub-pack having a third cell group. A cooling system supplies a liquid coolant to a heat exchanger that is in thermal communication with the battery pack. A first section, a second section, and a third section of the heat exchanger are arranged sequentially in a flow direction of the liquid coolant between the coolant inlet and the coolant outlet, with the first section of positioned adjacent to the first cell group of the first sub-pack, the second section positioned adjacent to the third cell group of the second sub-pack, and the third section positioned adjacent to the second cell group of the first sub-pack.

Abstract: A battery pack can include a plurality of battery cells arranged adjacent one another in a row. The battery pack can include a first spacer plate aligned with and positioned adjacent the first cell of the plurality of battery cells, a second spacer plate aligned with and positioned adjacent the last cell of the plurality of battery cells, and a housing enclosing the plurality of battery cells. The housing can include a first sidewall positioned adjacent the first spacer plate and a second sidewall positioned adjacent the second spacer plate such that the plurality of battery cells can be positioned between the first sidewall and the second sidewall. The battery pack can include a cover. A layer of adhesive can be disposed between the battery cells and the cover. Various techniques can be employed to improve the durability of the battery pack.

Abstract: A battery pack includes a first busbar, a second busbar, and a thermal interface material (TIM) including a thermal conductivity constant (k) value between 1.0 and 7.0 watts per meter-kelvin (W/mK). The TIM establishes a thermal interface between the first busbar and the second busbar. The battery pack also includes a control assembly configured to regulate a charging mode of the battery pack in which the first busbar is active and receives an electrical current and the second busbar is inactive.

Abstract: A battery pack can include an enclosure with a first panel opposite and spaced apart from a second panel. First and second battery cell stacks can be positioned between the first and the second panels. Each of the first and the second battery cell stacks can include a plurality of interconnected battery cells. A busbar fuse can be electrically connected between the first and the second battery cell stack and can include an exterior thermal contact that is thermally connected to the first panel. A thermal interface material (TIM) can be disposed between the exterior thermal contact and the first panel where the first panel can form a portion of a heat exchanger. A shell can at least partially enclose the busbar fuse and can retain a potting compound or phase change material around the busbar fuse.

Abstract: A battery pack includes an enclosure forming an enclosure interior, a stack of battery cells disposed within the enclosure interior, and an adhesive extending between a wall of the enclosure and the stack. The battery pack also includes a first gap filler extending between the wall and the stack, where the first gap filler is disposed adjacent to a first edge of the stack and includes a first thermal conductivity constant greater than a second thermal conductivity constant of the adhesive. The battery pack also includes a second gap filler extending between the wall and the stack, where the second gap filler is disposed adjacent to a second edge of the stack and includes a third thermal conductivity constant greater than the second thermal conductivity constant.
