The utility model relates to a train tail battery with a stable structure, which comprises a shell and a battery module, the shell is a cylinder which is composed of a bottom shell and an upper cover detachably connected to the bottom shell, the cross section of the cylinder is triangular, the cylinder is provided with an accommodating space matched with the battery module, the battery module is arranged in the accommodating space, and the battery module is arranged in the accommodating space. The battery module is of a triangular cylinder structure formed by arranging a plurality of cylindrical battery cells into a triangle, and a connecting piece connected with the battery module is arranged on the outer side face of the bottom of the shell. The battery cells of the train tail battery are arranged in a triangular shape, gaps among the battery cells are small, compared with rectangular or square arrangement, space is saved, the size of a battery shell can be reduced, space layout optimization of a train tail main machine is facilitated, and the battery cells arranged in the triangular shape are arranged in a convex-concave staggered mode and tightly attached to each other to form a resultant force supporting effect. The possibility that the train tail battery is impacted or vibrated to shake and shift in the using process is reduced, and the structural stability of the train tail battery is improved.
