    • A battery pack includes a circuit board and a battery cell group disposed within a battery case. The battery cell group includes a plurality of cylindrical battery cells staggered from each other so that the battery cell group includes at least a first battery cell stage and a second battery cell stage. The first battery cell stage is positioned on the side of the circuit board. The second battery cell stage is positioned adjacent to the first stage on the side away from the circuit board. The first battery cell stage includes a first battery cell and a second battery cell positioned at opposite ends of the first battery cell stage and a central battery cell positioned between the first and the second battery cell. The central battery cell is spaced from the circuit board by a distance, so that the central battery cell does not interfere with the circuit elements of the circuit board.
    • 电池组包括设置在电池壳体内的电路板和电池单体组。 电池单元组包括彼此交错的多个圆柱形电池单元,使得电池单元组至少包括第一电池单元级和第二电池单元级。 第一个电池单元级位于电路板的一侧。 第二电池单元级位于远离电路板的一侧与第一级相邻的位置。 第一电池单元级包括位于第一电池单元级的相对端的第一电池单元和第二电池单元以及位于第一和第二电池单元之间的中央电池单元。 中央电池单元与电路板隔开一段距离,使得中央电池单元不干扰电路板的电路元件。
