[0017] The utility model is further described below with reference to the accompanying drawings.

[0018] like Figures 1 to 5 As shown, the upper end of the base 1 is connected to a plurality of stacked battery modules 2, and the upper end of the battery module 2 is connected to the electric control box 3. A circle of bosses 4 are provided at the upper ends of the base 1 and the battery module 2, and a circle of concave edges 5 that match the structure of the bosses 4 are provided at the lower ends of the electric control box 3 and the battery module 2. The concave edges 5 and the bosses 4 cooperate with each other when stacked up and down, playing a guiding role and limiting the horizontal displacement. The utility model adopts an overall circle of concave edges and bosses, and uses sheet metal parts for one-piece molding during processing to simplify the processing technology. At the same time, a circle of concave edges and protrusions can play a better waterproof role after the products are stacked.

[0019] The lower end of the battery module 2 is provided with a concave first installation opening 9, in which a first quick-plug terminal 6 is provided, and the upper end of the battery module 2 is provided with a convex second installation opening 8, in which a second quick-plug terminal 7 is provided. When installing, the battery modules 2 are stacked, and the first quick-plug terminal 6 of the upper battery module 2 is inserted into the second quick-plug terminal 7 of the lower battery module 2. The product connection can be achieved by simply stacking the products. At the same time, it plays a role in rapid positioning.

[0020] A wall-mounted bracket 10 is provided on one side of the electric control box 3 . After the base 1 , the battery module 2 , and the electric control box 3 are assembled, the entire energy storage system is fixed against the wall by the wall-mounted bracket 10 .

[0021] The battery module 2 includes a lower shell 21 and an upper cover 22. The upper end of the lower shell 21 is connected to the upper cover 22. A circle of sealing foam 23 is provided at the connection between the lower shell 21 and the upper cover 22 to improve the sealing performance and ensure that the single battery module 2 meets the protection requirements.

[0022] The side wall of the concave edge 5 is provided with a bolt mounting hole 51, and the side wall of the boss 4 is provided with a nut mounting opening that matches the position of the bolt mounting hole 51, and the nut mounting opening is provided with a fixing nut 41. The stacked boxes are connected together with the base 1 and the electric control box 3 by the fixing screws 13, the bolt mounting holes 51, and the fixing nuts 41, so as to ensure the stability of the product in the vertical direction.

[0023] A handle 11 is provided on the side of the battery module 2 to facilitate the transportation and installation of the battery module 2 .

[0024] The stacking quantity of battery modules 2 is 2-6.

[0025] An arc-shaped groove 12 is provided at the lower end of the base 1, so that the base 1 forms a four-point support structure. The four-point support can effectively prevent the product from being placed unsteadily due to uneven ground.

[0026] The corners of the base 1, battery module 2, and electric control box 3 are all rounded. The smooth transition structure prevents scratches that are easily caused by right-angle structures.

[0027] In the utility model, the base 1, the battery module 2, and the electric control box 3 can be transported separately, reducing the difficulty of transportation. In addition, since the concave edge 5 at the lower end of the battery module 2 forms a flat surface, the battery module 2 will not fall over when laid flat, ensuring the safety of transportation.

[0028] During installation, the battery modules 2 and the electric control box 3 are stacked on the base 1 in sequence, and the quick-plug terminals of the upper and lower battery modules 2 are matched to complete the connection of the battery modules 2.
