If the curved surface is flattened, a small area will be lacking at some parts of the edge, as shown in fig. 1. When the module is designed, the battery size is fixed, the general shape is a plane rectangle or square, and a plurality of battery pieces are still in the plane rectangle or square after being connected in series, which is equivalent to the projection area; when the battery string is placed on the 3D curved surface, the battery string is subjected to clearance change due to the fact that the same projection area corresponds to the curved surface with different areas, the clearance of the battery string is small at the position with small curvature change, the opposite clearance is large, and the appearance effect of the assembly is seriously affected.
