Abstract: A battery case (100) is provided, including a plurality of side plates. A first side plate (110) has the largest area among the plurality of side plates, and at least one first side plate (110) includes a first portion (111) and a second portion (112). The first portion (111) is a curved surface concave toward inside of the battery case (100). A three-dimensional coordinate system is established in a first direction, a second direction, and a third direction, and the second direction is perpendicular to the first side plate. A curvature of the first portion is less than a curvature of an ellipsoid, the curvature of the ellipsoid is obtained from an ellipsoid function, and the ellipsoid function is: ((x-a)/i) 2 +((y-b)/j) 2 +((z-c)/k) 2 =1, where, a, b, c, i, j, and k are determined according to coordinates of at least four points that are different from each other, and x, y, and z are coordinates of the three directions of the ellipsoid function.
