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.
