BATTERY PACK DEVICE WITH CASINGS FOR MULTIPLE CELLS

The invention relates to a battery pack device with casings for multiple cells. In some examples, a high-energy-density battery pack device includes a circuit board and at least two easing structuresmounted on the circuit board. In some examples, the high-energy-density battery pack device also includes at least two cells electrically connected in series or in parallel through the circuit board.In some examples, each cell of the at least two cells is positioned in a casing structure of the at least two casing structures. In some examples, the respective casing structure surrounds the respective cell with an opening on one end of the cell. 本发明涉及种具有用于多个电池单元的壳体的电池组设备。在些示例中，高能量密度电池组设备包括电路板和安装在电路板上的至少两个壳体结构。在些示例中，高能量密度电池组设备还包括通过电路板串联或并联电连接的至少两个电池单元。在些示例中，所述至少两个电池单元中的每个电池单元定位在所述至少两个壳体结构中的壳体结构中。在些示例中，相应的壳体结构围绕相应的电池单元并在电池单元的端具有开口。
