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 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.
