Description

Technical Field

[0001] This utility model relates to the field of energy storage battery technology, specifically a wall-mounted energy storage battery. Background Technology

[0002] UPS and inverters are the main equipment for commercial and home appliances and emergency power supplies. They are mainly used to provide a continuous and clean power supply for equipment with high power stability requirements. Their main components include rectifiers, battery packs, inverters and static switches. Among them, the battery pack is one of the important core components, also known as energy storage batteries. It is used to release DC power to the inverter to convert AC power to power the equipment when the mains power is interrupted.

[0003] The aforementioned energy storage batteries generally come in several design types, including wall-mounted and drawer-type. Wall-mounted batteries are primarily convenient for installation on walls or other wall surfaces, reducing floor space requirements. However, in practical use, wall-mounted energy storage batteries require maintenance or repair, sometimes necessitating the removal of the entire battery pack or certain batteries from the enclosure for easier access. Unfortunately, due to design flaws, existing wall-mounted energy storage batteries lack modularity, making them inconvenient for users to disassemble and replace, thus increasing maintenance time and impacting equipment usability. Utility Model Content

[0004] The purpose of this invention is to provide a wall-mounted energy storage battery that integrates the casing, storage box, and battery cells as separate modules, making operation simple and convenient. During maintenance or cell replacement, only a portion of the cells can be replaced, or the entire storage box and battery cells can be replaced as a whole, improving maintenance efficiency. This modular battery design offers greater flexibility in manufacturing, end-user maintenance, and after-sales safety applications, significantly aiding in production and quality technology. All modules can be mass-produced using universal modules, improving enterprise quality and efficiency, thus addressing the problem mentioned in the background that most existing wall-mounted energy storage batteries are inconvenient for users to disassemble and replace.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A plurality of battery cells 3 are stacked and connected in series between the rear protective cover 21 and the front cover plate 22. A lower connector 23 detachably mounted on the inner wall of the rear shell 11 is connected to the bottom end of the rear protective cover 21, and an upper connector 24 detachably mounted on the inner wall of the rear shell 11 is connected to the top end of the rear protective cover 21. In this embodiment, the plurality of battery cells 3 are separated from each other by an insulating plate to prevent short circuits and leakage. There are at least two storage boxes 2, and the battery cells 3 between the two storage boxes 2 are connected in series.

[0030] The housing 1, storage box 2, and battery cell 3 are separate modules. During installation, the battery cell 3 is first housed in the rear protective cover 21, and then the front opening of the rear protective cover 21 is covered by the front cover plate 22. Next, the lower connector 23 and the upper connector 24 are connected to the rear protective cover 21 respectively. Finally, the lower connector 23 and the upper connector 24 are installed in the rear shell 11. The operation is simple and the installation is convenient. Therefore, when inspecting or replacing the battery cell 3, the lower connector 23 and the upper connector 24 can be removed from the inner wall of the rear shell 11, and the entire storage box 2 and battery cell 3 can be replaced as a whole. Alternatively, the front cover plate 22 can be opened, and the battery cell 3 that needs to be repaired or replaced can be removed from the rear protective cover 21. The disassembly and assembly are convenient, improving the efficiency of maintenance. In addition, different specifications of battery cells 3 can be stored in the rear protective cover 21. Different specifications of battery cells 3 can be installed in the housing 1 through the storage box 2, which has good versatility.

[0031] Please see Figure 5-6 In this embodiment, the lower connector 23 and the upper connector 24 are arranged symmetrically, and the structure of the lower connector 23 is the same as that of the upper connector 24. The upper connector 24 includes a base plate 241 and two side plates 242 respectively perpendicularly connected to the two edges of the base plate 241. Each of the two side plates 242 has a limiting hole 243. Please refer to [link / reference]. Figure 4 The rear shell 11 has a fixing plate 13 on its upper and lower inner walls respectively. The two fixing plates 13 are respectively provided with a limiting post 14 inserted into the limiting hole 243. The end of the limiting post 14 is tapered so that it can be aligned and inserted into the limiting hole 243 when the storage box 2 is installed.
