[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 and Figure 2 The present invention provides an embodiment of an energy storage system structure that utilizes the entire package, comprising a body 1, with multiple cascaded battery packs 5 inside the body 1, a PCS7 below the cascaded battery packs 5, an electrical mounting plate 8 on one side of the PCS7, a liquid cooling unit 6 inside the body 1, a cabinet door 3 connected to the outside of the body 1 by hinges, a dehumidifier 9 on the inside of the cabinet door 3, two heat dissipation grilles 10 on the surface of the cabinet door 3, a dustproof net 12 on one side of the heat dissipation grilles 10, and a disassembly assembly inside the cabinet door 3.

[0027] Specifically, the energy storage system of this device mainly consists of three secondary battery packs 5, one liquid cooling unit 6, three PCS7, an electrical mounting plate 8, and a dehumidifier 9. During assembly, each component is installed in its designated position and connected to the corresponding circuit, enabling these components to work together to achieve the storage and conversion of electrical energy. Through the cooling of the liquid cooling unit 6 and the operation of the dehumidifier 9, the battery is ensured to operate within a suitable temperature and humidity range, ensuring the efficient and stable operation of the energy storage system. In use, the components on the electrical mounting plate 8 are connected to an external power source, and the PCS7 is used to convert AC and DC voltage, converting electrical energy into chemical energy for storage in the secondary battery packs 5. When discharge is required, the chemical energy in the battery pack is converted into electrical energy through the discharge equipment, and then converted into AC power by PCS7 and output to the grid or load. At the same time, the liquid cooling unit 6 absorbs the heat generated in the battery pack through circulating liquid and dissipates the heat generated during operation by cooling, ensuring that the battery pack operates within the optimal operating temperature range. The dehumidifier 9 removes moisture from the air inside the enclosure to maintain the ambient humidity within a suitable range, preventing equipment failure and safety hazards. The energy storage system structure of this device has the advantages of high efficiency, stability and reliability, and can be widely used in renewable energy power generation, power system dispatching and peak-valley balancing.

[0028] Reference Figure 3 , Figure 5 and Figure 6 The assembly includes a slide bar 16, a telescopic spring 17, a slide plate 14, and a plug rod 18. Two slide bars 16 are fixedly installed inside the cabinet door 3. The telescopic spring 17 is sleeved on the outside of the slide bar 16. The slide plate 14 is movably installed on the slide bar 16. The plug rod 18 is fixedly installed on one side of the slide plate 14. The surface of the cabinet door 3 has an installation groove 19, and the plug rod 18 extends into the installation groove 19. A fixing block 15 is fixedly connected to one side of the slide plate 14. A lever 11 is fixedly connected to one side of the fixing block 15. The surface of the cabinet door 3 has a moving groove 13, and the fixing block 15 is placed inside the moving groove 13. Installation blocks 20 are fixedly connected to both sides of the dustproof net 12. A plug hole 21 is opened on one side of the installation block 20.

[0029] Specifically, the size and dimensions of the socket 21 correspond to the size and dimensions of the rod 18, and the size and dimensions of the mounting block 20 match the size and dimensions of the mounting groove 19. By installing the mounting block 20 into the mounting groove 19 and moving the lever 11, the lever 11 drives the slide plate 14 to slide on the slide rod 16 through the fixing block 15. As the slide plate 14 moves, it compresses the telescopic spring 17 inward. The movement of the slide plate 14 can also drive the rod 18 to move. After moving the rod 18 a certain distance, the mounting block 20 is completely placed inside the mounting groove 19. At this time, the position of the rod 18 is equivalent to the socket 21. When the lever 11 is released, the telescopic spring 17 can push the slide plate 14 to reset through the reverse force. The slide plate 14 can then drive the rod 18 to be inserted into the socket 21. In this way, the dustproof net 12 can be fixedly installed on the outside of the heat dissipation grille 10, thereby preventing dust from entering the interior of the body 1 through the heat dissipation grille 10 and affecting the normal operation of the internal devices of the body 1.

[0030] Reference Figure 4 The surface of the electrical mounting plate 8 is provided with a resistor 26, below the resistor 26 is a transformer 22, below the transformer 22 is a capacitor 23, on one side of the capacitor 23 is a relay 24, and on one side of the relay 24 is a potentiometer 25.

[0031] Specifically, the electrical circuits can be constructed through the various electrical components on the electrical mounting plate 8, ensuring the normal operation of the device. The internal structure 1 also houses an integrated battery management system (BMS). The integrated battery management system mainly consists of a main board, slave boards, BDU, high-voltage control board, and other external software modules. The BMS system can monitor the battery status in real time, including key parameters such as voltage, current, and temperature. This ensures the safe and stable operation of the energy storage system and avoids safety hazards such as overcharging, over-discharging, and short circuits. At the same time, the BMS system can also provide functions such as battery life prediction and fault warning, improving the reliability and economy of the system.

[0032] Reference Figure 1 The top of the body 1 is fixedly connected to the four corners of the lifting ring 2, and the body 1 is equipped with a partition 4 inside.

[0033] Specifically, the machine body 1 can be hoisted to the designated position using the lifting ring 2.

[0034] Working Principle: When using this device, the main body 1 can be hoisted to the designated position using the lifting ring 2. Each component is then sequentially installed in its designated position and connected to the corresponding wiring, enabling these components to work collaboratively. This achieves the storage and conversion of electrical energy. The cooling of the liquid chiller unit 6 and the operation of the dehumidifier 9 ensure that the battery operates within a suitable temperature and humidity range, guaranteeing the efficient and stable operation of the energy storage system. During use, the components on the electrical mounting plate 8 are connected to an external power source. The PCS7 converts the AC / DC voltage, transforming electrical energy into chemical energy stored in the cascaded battery pack 5. When discharge is required, the chemical energy in the battery pack is converted into electrical energy through a discharge device and then converted back to AC power by the PCS7 for output to the power grid or load. Simultaneously, the liquid chiller unit 6 absorbs the heat generated in the battery pack through circulating liquid and dissipates the heat through cooling. The heat generated ensures the battery pack operates within its optimal temperature range. The dehumidifier 9 removes moisture from the air inside the cabinet, maintaining ambient humidity within a suitable range to prevent equipment malfunctions and safety hazards. The dustproof net 12 prevents dust from entering the interior of the unit 1 through the heat dissipation grille 10, thus affecting the normal operation of the various devices inside the unit 1. When the dustproof net 12 has been used for too long and affects the normal heat dissipation of the unit 1, the lever 11 can be moved. The lever 11 drives the slide plate 14 to slide on the slide rod 16 through the fixing block 15. The slide plate 14 drives the insertion rod 18 to move, disengaging the insertion rod 18 from the insertion hole 21, thereby releasing the fixing state of the mounting block 20. At this time, the dustproof net 12 can be removed from the cabinet door 3 for easy cleaning. This device enhances the high efficiency and stability of the energy storage system while also facilitating the removal and cleaning of the dustproof net 12.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
