[0020] To enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art should fall within the protection scope of the present invention.

[0021] The excessive number of screws on the inspection port cover of existing energy storage battery packs leads to maintenance difficulties and stripping of screws, among other problems. Based on this, the main concept of this application is to propose an energy storage battery pack with an insert-type mounting cover. The cover uses an insert-type mounting combined with screw locking, which greatly improves the efficiency and stability of the cover installation and removal.

[0022] A further idea is to place a sealing ring on at least one of the opposite sides of the cover plate, which not only ensures a sealing effect but also improves the maintainability of the energy storage battery pack.

[0023] The energy storage battery pack includes an outer casing and battery modules installed inside the casing. An inspection port is provided on one side of the casing to facilitate routine inspections, performance checks, maintenance, and repairs by staff.

[0024] The energy storage battery pack also includes a cover for closing the inspection port, which is inserted into the outer casing.

[0025] The housing includes multiple side plates, a first end plate disposed at one end of the multiple side plates, and a second end plate disposed at the other end of the multiple side plates. The multiple side plates, the first end plate, and the second end plate together enclose a receiving cavity for accommodating a battery module. The battery module is installed in the receiving cavity, and an inspection port is opened in the middle of the first end plate.

[0026] The attached diagram does not show the structure of the entire outer casing, but rather the specific structure of the first end plate, as shown in the attached diagram. Figure 2 , Figure 2 A schematic diagram of the structure of the first end plate of an energy storage battery pack according to an embodiment of the present invention is shown.

[0027] Depend on Figure 2 As can be seen, the first end plate 1 includes a first plate portion 1a and a second plate portion 1b integrally connected to the outer side of the first plate portion 1a. An inspection port 200 is opened in the middle of the first plate portion 1a and the second plate portion 1b. A receiving groove is formed between the first plate portion 1a and the second plate portion 1b. The first plate portion 1a is connected to multiple side plates.

[0028] Figure 3 A schematic diagram of the structure of the cover plate of an energy storage battery pack according to an embodiment of the present invention is shown.

[0029] Depend on Figure 3 As can be seen, the cover plate 100 includes a cover body 2 and a plurality of sealing rings 3 disposed on at least one of the two opposing surfaces of the cover body 2. A screw is movably disposed on one side of the cover body 2. The sealing rings 3 are made of rubber to achieve the sealing of the energy storage battery pack. The cover body 2 is inserted into the receiving groove formed between the first plate portion 1a and the second plate portion 1b.

[0030] In some embodiments, a plurality of sealing rings 3 are provided on at least one surface of the cover body 2 facing the first plate portion 1a. In order to ensure sealing performance, a plurality of sealing rings 3 are provided on two opposite surfaces of the cover body 2. In addition, each sealing ring 3 is arranged along the circumference of the cover body 2, and the plurality of sealing rings 3 are arranged sequentially from the inside to the outside of the cover body 2 at intervals.

[0031] Placing the sealing ring 3 on the cover body 2 also improves the maintainability of the energy storage battery pack. The sealing ring can be installed by embedding, such as by setting grooves on the cover body 2 corresponding to the positions of each sealing ring 3, so that the sealing ring 3 is embedded in the grooves and is not easy to fall off.

[0032] See Figure 4 As shown, Figure 4 A schematic diagram of the structure of a first end plate and a cover plate combined in an embodiment of the present invention is shown.

[0033] Depend on Figure 4 As can be seen, the cover body 2 is inserted into the first end plate 1. The first end plate 1 has threaded holes corresponding to the positions of the screws 300, so that the cover body 2 and the first end plate 1 are detachably connected by the screws 300. The insertion and installation of the cover plate, combined with the fixing of the screws 300 to the first end plate 1, results in high efficiency in disassembly and assembly of the cover plate and good installation stability.

[0034] See also Figure 2 and Figure 4 The receiving groove formed between the first plate portion 1a and the second plate portion 1b can cooperate with the cover body 2. The cover body 2 is inserted into the receiving groove, and the threaded hole is provided on the first plate portion 1a, so that the cover body 2 and the first plate portion 1a are detachably connected by screws 300.

[0035] To facilitate operation, a notch is provided in the second plate 1b corresponding to the position of the screw 300. The notch is used to avoid the screw 300 and to facilitate the operator to rotate the screw 300. At the same time, the notch also makes it easy for the operator to remove the cover plate from the receiving groove formed between the first plate 1a and the second plate 1b.

[0036] In some embodiments, a screw 300 is movably disposed on the cover body 2, and the detachable connection between the cover plate 100 and the outer shell is achieved by only one screw 300, avoiding the difficulties of disassembly and assembly and the problem of stripping caused by multiple screws.

[0037] When the cover body 2 is inserted into the receiving groove formed between the first plate portion 1a and the second plate portion 1b, the sealing ring 3 on the surface of the cover body 2 facing the first plate portion 1a is located between the cover body 2 and the first plate portion 1a, and the sealing ring 3 on the surface of the cover body 2 facing the second plate portion 1b is located between the cover body 2 and the second plate portion 1b, thus providing good sealing performance.

[0038] In some embodiments, the cover body 2 is square, and the first plate portion 1a and the second plate portion 1b may also be square. The second plate portion 1b has four sides, three of which are connected to the first plate portion 1a and the last side is separated from the first plate portion 1a, thereby forming a receiving groove for accommodating the cover body 2, which facilitates the insertion or removal of the cover body 2 into the receiving groove and facilitates the assembly and disassembly of the cover body 2.

[0039] The energy storage battery pack of this invention features a design where a receiving groove for accommodating a cover plate 100 is provided on the first end plate 1 of the outer casing, combined with a single screw 300. The cover plate 100 is fixed to the outer casing by only one screw 300. Combined with the design of a sealing ring, this design ensures sealing and safety while achieving easy maintenance and avoids problems such as stripping caused by too many screws, thus improving the operation and maintenance efficiency of the energy storage system.
