[0029] Existing traditional energy storage cabinets often integrate batteries, modules, and control units into a single structure. This not only increases the complexity of the system but also limits its scalability and flexibility. In addition, the battery module in the energy storage system is the core component for energy storage. Once a failure or thermal runaway occurs, it may lead to serious consequences such as fire or explosion.

[0030] Based on this, this utility model embodiment provides a small energy storage cabinet. The cabinet includes a first cavity, a second cavity, a third cavity, and a fourth cavity, which are independent of each other. The first cavity houses the battery box and contains a cooling device and a return air duct. The return air duct is located at the top of the first cavity, and the cooling device is located below it. The return air duct collects airflow from the cooling device. The second cavity houses the energy storage converter and the high-voltage box and is equipped with a fan to dissipate heat from the second cavity to the outside of the cabinet. The third cavity has quick-connect connectors, and the fourth cavity houses electrical components. This design, based on a reasonable layout and heat dissipation design, ensures the safe operation of the battery modules. This design not only improves the integration and scalability of the energy storage cabinet but also facilitates subsequent maintenance and upgrades.

[0031] Therefore, the embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, Figure 1 This is a perspective view of a small energy storage cabinet provided in one embodiment of the present invention. Figure 2 This is a front view of a small energy storage cabinet provided in one embodiment of the present invention. Figure 3 This is a perspective view of a small energy storage cabinet provided in another embodiment of the present invention. Figure 4 This is a perspective view of a small energy storage cabinet provided in another embodiment of the present invention. The small energy storage cabinet is provided with a cabinet body 100. The cabinet body 100 includes a first cavity 200, a second cavity 300, a third cavity 400 and a fourth cavity 500. The first cavity 200, the second cavity 300, the third cavity 400 and the fourth cavity 500 are independent of each other and are isolated from each other by a partition.

[0033] The first cavity 200 is used to house the battery box. The interior of the first cavity 200 is equipped with a cooling device 201 and a return air duct 202. The return air duct 202 is located at the top of the first cavity 200, and the cooling device 201 is located below the return air duct 202. The return air duct 202 is used to collect the airflow of the cooling device 201. The second cavity 300 is used to house the energy storage converter and the high-voltage box. The second cavity 300 is equipped with a fan 301, which is used to guide the heat of the second cavity 300 to the outside of the cabinet 100. The third cavity 400 is equipped with a quick-connect connector 401. The fourth cavity 500 is used to house electrical components.

[0034] In the first cavity 200, the layout of the refrigeration unit 201 and the return air duct 202 is rationally designed. The return air duct 202, located at the top, effectively collects the cold air generated by the refrigeration unit 201 and guides it throughout the entire first cavity 200, resulting in a more uniform temperature distribution within the cavity and ensuring stable operation of the equipment placed inside (if temperature-sensitive components are present) under suitable temperature conditions. The refrigeration unit 201, located below the return air duct 202, facilitates the rising and circulation of cold air, improving refrigeration efficiency and reducing energy loss. It also facilitates the collection and discharge of condensate, preventing condensate accumulation within the cavity that could cause moisture damage to the equipment.

[0035] Furthermore, in the second cavity 300, the fan 301 is used to conduct heat to the outside of the cabinet 100, providing an effective heat dissipation method for the energy storage converter and high-voltage box. The energy storage converter and high-voltage box generate a large amount of heat during operation. If this heat cannot be dissipated in time, it can lead to overheating, affecting their performance and lifespan, and may even cause safety accidents. The presence of the fan 301 forces the hot air out of the cavity, reducing the internal temperature and ensuring that the energy storage converter and high-voltage box operate within a safe temperature range, improving the reliability and stability of the equipment. It also helps improve the overall system's heat dissipation efficiency, preventing localized overheating.

[0036] Next, the quick-connect connector 401 in the third cavity 400 greatly facilitates the installation and maintenance of the equipment. The quick-connect connector 401 features convenient, quick, and reliable connection, enabling rapid plugging and unplugging of electrical connections without the need for complex tools or cumbersome wiring operations. During equipment installation, it saves significant time and labor costs, improving installation efficiency. During equipment maintenance, if a component needs to be replaced or repaired, the quick-connect connector 401 can easily disconnect the component from the system without affecting other components, making maintenance more convenient and efficient, reducing equipment downtime, and improving equipment availability.

[0037] It is worth noting that the fourth chamber 500 is used to house electrical components. Concentrating these components within a single, independent chamber facilitates unified management and maintenance. This prevents external environmental interference, such as dust, moisture, and electromagnetic interference, improving the reliability and stability of the components. Furthermore, this centralized placement method simplifies wiring and connections, resulting in neater, clearer wiring, easier troubleshooting, and routine maintenance, ultimately enhancing the overall system's safety and maintainability.

[0038] Furthermore, the first cavity 200 is connected to the first side and the second side of the cabinet 100, and the first side and the first side are opposite to each other. The cabinet 100 also includes a first cabinet door 110 and a second cabinet door 120. The first cabinet door 110 is located on the first side and covers the first cavity 200, and the second cabinet door 120 is located on the second side and covers the first cavity 200.

[0039] Furthermore, the second cabinet door 120 is also equipped with an air outlet device 121. The air outlet device 121 connects the inner and outer sides of the second cabinet door 120, and its position corresponds to the position of the return air duct 202. The air outlet device 121 is used to exhaust the airflow from the return air duct 202 to the outside of the cabinet 100. The cooperation between the air outlet device 121 and the return air duct 202 forms a relatively complete airflow path. Cold airflow generated from the cooling unit 201 is collected through the return air duct 202 and then exhausted through the air outlet device 121. This design makes the airflow within the cabinet 100 more orderly and efficient. Compared to the case without the air outlet device 121, it can more effectively guide the airflow, avoid turbulence or local stagnation of airflow within the cabinet 100, ensure a smoother heat exchange process, improve the efficiency of the entire heat dissipation system, help maintain a relatively uniform temperature distribution within the cabinet 100, and is conducive to the long-term stable operation of the equipment.

[0040] Furthermore, the second cavity 300 connects to the first and second sides. The cabinet 100 also includes a third door 130 and a fourth door 140. The third door 130 is located on the first side and covers the second cavity 300, and the fourth door 140 is located on the second side and covers the second cavity 300. Both the third door 130 and the fourth door 140 are equipped with louvers 141, which serve as airflow channels for the fan 301. These louvers effectively guide the airflow generated by the fan 301, allowing the airflow to flow more orderly through the second cavity 300 and quickly dissipating heat from the cavity to the outside of the cabinet 100. Compared to the case without louvers 141 for airflow guidance, this design improves heat dissipation efficiency, ensuring that equipment such as the energy storage converter and high-voltage box placed inside the second cavity 300 can operate in a suitable temperature environment. This reduces the risk of equipment failure due to overheating, extends the service life of the equipment, and improves the stability and reliability of equipment operation.

[0041] Furthermore, the third cavity 400 is connected to the first side, and the cabinet 100 also includes a fifth cabinet door 150, which is located on the first side and covers the third cavity 400.

[0042] Furthermore, the fourth cavity 500 is connected to the third side of the cabinet 100. The cabinet 100 also includes a sixth cabinet door 160, which is located on the third side and covers the fourth cavity 500. The sixth cabinet door 160 is equipped with a control panel 161, which is connected to the outer and inner sides of the sixth cabinet door 160. The control panel 161 is used as a detection component for operators to view the internal equipment.

[0043] Furthermore, the cabinet 100 is also equipped with a charging pile 170 and a charging gun 180. The charging pile 170 is mounted on a third side and located on one side of the sixth cabinet door 160. The charging gun 180 is mounted on a third side and located on one side of the sixth cabinet door 160. The charging gun 180 is electrically connected to the charging pile 170. The charging pile 170 is used to convert the voltage of the battery box into the rechargeable voltage of the electric vehicle, and the charging gun 180 is used to charge the electric vehicle.

[0044] Furthermore, the cabinet 100 is also equipped with a handheld fire extinguisher 190, which is mounted on a second side and located on one side of the fourth cabinet door 140.
