    • A battery case (1, 8), substantially square in cross section, has four lateral walls (5, 6) each of which is gradually arc-shaped to expand outwardly with a radius of curvature R1. The cross section is adapted to satisfy equation R1/r=4 to 20, where r is the distance between a midpoint (C2) of each lateral wall (5, 6) and the center point (C1) in the cross section of the battery case (1, 8) and R1 is the radius of curvature. In addition, the battery case (8) is rounded at each corner with a radius of curvature of R2, and has a cross section that satisfies equation R2/r=0.3 to 0.8, where r is the distance between the midpoint (C2) of each lateral wall (6) and the center point (C1) in the cross section of the battery case (8) and R2 is the radius of curvature of each corner.
    • 基本上为正方形的电池壳体(1,8)具有四个侧壁(5,6),每个侧壁逐渐地弧形以向外以曲率半径R1向外扩展。 横截面适于满足方程式R1 / r = 4至20,其中r是电池横截面中每个侧壁(5,6)和中心点(C1)的中点(C2)之间的距离 情况(1,8),R1是曲率半径。 此外,电池壳体(8)在每个拐角处具有曲率半径R2,并且具有满足等式R2 / r = 0.3至0.8的横截面,其中r是中间点(C2)之间的距离 电池壳体(8)的横截面中的每个侧壁(6)和中心点(C1),并且R2是每个拐角的曲率半径。
