[0039] like Figures 1 to 6 As shown, the present application provides an energy storage cabinet, including a cabinet body 1 having an equipment compartment, a battery module 2, a refrigeration component 3 and a control component 7 installed in the equipment compartment.

[0040] Among them, the battery module 2 serves as the energy storage core and is responsible for the storage and release of electrical energy. In order to ensure that the battery module 2 can operate within the most suitable temperature range, the cold end of the refrigeration component 3 is in contact with the battery module 2, thereby forming heat conduction to accurately control the battery module temperature, effectively extend the battery life, and maintain its healthy state. Specifically, the cold end of the refrigeration component 3 has a battery module flow channel and a refrigeration water inlet pipe and a refrigeration water outlet pipe that form a closed loop. The refrigerant flows into the battery module flow channel through the refrigeration water inlet pipe, thereby realizing heat exchange with the battery module 2. The control component 7, as the intelligent control center of the energy storage cabinet, can not only automatically adjust the working intensity of the refrigeration component 3 according to the actual temperature of the battery module 2, but also flexibly adjust the battery charging and discharging strategy according to external instructions or preset programs to ensure the safety and efficiency of the energy storage cabinet operation.

[0041] The logic control process of the control component 7 on the battery module 2 and the refrigeration component 3 is as follows:

[0042] During the charging process, the control component 7 receives remote instructions to charge the battery pack 21 in the battery module 2. The sensor monitors the temperature of the battery pack 21. When the temperature rises to a limit value, the refrigeration component 3 starts to dissipate heat for the battery pack 21. After the battery pack 21 is fully charged, the feedback is sent to the control component 7. The control component 7 controls the refrigeration component 3 to shut down, and the charging is completed.

[0043] During the discharge process, the control component 7 receives a remote command to discharge the battery pack 21. The sensor monitors the temperature of the battery pack 21. When the temperature rises to a limit value, the refrigeration component 3 starts to dissipate heat from the battery pack 21. After the battery pack 21 reaches the limit value, feedback is sent to the control component 7. The control component 7 controls the refrigeration component 3 to shut down, and the discharge is completed.

[0044] To further enhance the energy storage cabinet's space utilization efficiency and module independence, the cabinet also includes multiple partitions 4. These partitions 4 are positioned between the battery module 2 and the refrigeration assembly 3, and between the refrigeration assembly 3 and the control assembly 7. These partitions separate the battery module 2, refrigeration assembly 3, and control assembly 7 within the equipment compartment. These partitions not only effectively isolate the physical space between the functional modules, preventing potential electromagnetic interference and thermal interference, but also isolate leakage and condensation. Furthermore, they provide a more stable overall structure and facilitate maintenance and upgrades.

[0045] Compared to traditional energy storage cabinets, the energy storage cabinet in this application is significantly smaller, only about 70% of the size of similar products. This significantly reduces floor space, reduces processing and transportation costs, and improves space utilization. Its convenient on-site installation provides an ideal energy solution for a variety of application scenarios, such as small and medium-sized industrial and commercial parks, photovoltaic storage and charging stations, and effectively solves the pain points of traditional energy storage cabinets in terms of deployment flexibility, cost-effectiveness, and spatial adaptability.

[0046] In one embodiment of the present application, the cabinet 1 includes a vent, and an air inlet louver 5 and an air outlet louver 6 installed at the vent. The vent is connected to the equipment compartment. Specifically, the air inlet louver 5 is installed at the air inlet side vent, and the air outlet louver 6 is installed at the air outlet side vent. These louvers are responsible for smoothly discharging heat generated in the equipment compartment and any moisture and harmful gases that may accumulate, thereby ensuring stable temperature and humidity within the compartment and providing the necessary environmental conditions for the normal operation of key components such as the battery module 2, the refrigeration assembly 3, and the control assembly 7.

[0047] In one embodiment of the present application, the air inlet louver 5 comprises a window 51, and blades 52, dustproof cotton 53, steel mesh 54, and a cover plate 55 arranged in the order from the outside to the equipment compartment. The window 51 is mounted on the vent, the blades 52 are welded to the window 51, and the dustproof cotton 53 is sandwiched between the blades 52 and the steel mesh 54. The dustproof cotton 53 not only prevents dust but also effectively blocks water droplets. The cover plate 55 presses against the steel mesh 54 to secure the dustproof cotton 53.

[0048] In one embodiment of the present application, the bottom end of the cover plate 55 has a diversion bend 551, which is used to divert water to the outer side of the window 51. The special bending structure of the diversion bend 551 can guide water vapor intercepted by the cover plate 55 to the outer side of the window 51, and then discharge it out of the equipment compartment, achieving multiple functions such as air intake, dust prevention, and rain protection.

[0049] In one embodiment of the present application, the exhaust louver 6 includes a louver body 61 and an air guide cover 62 , and the air guide cover 62 is connected to the exhaust inlet end of the louver body 61 .

[0050] In one embodiment of the present application, the air guide cover 62 has a guide slope 621 at the bottom. The lowest point of the guide slope 621 is close to the exhaust inlet end of the shutter body 61, and the guide slope 621 is higher than the bottom slope of the shutter body 61. The guide slope 621 guides the air, thereby achieving the effects of air diversion and waterproofing.

[0051] In one embodiment of the present application, the battery module 2 includes a battery pack 21, a joist 22, and a baffle 23. The joist 22 is connected to the cabinet 1, and the battery pack 21 is supported on the joist 22. The joists 22 and baffles 23 are arranged in pairs, with the paired joists 22 located on either side of the battery pack 21. The paired baffles 23 are respectively connected to the corresponding joists 22 and located on the same side of the joist 22. Specifically, the joists 22 and baffles 23 are used to limit the battery pack 21. The left and right joists 22 and their rear locating pins limit the battery pack 21 in the upper and lower directions, and the left and right baffles 23 limit the battery pack 21 in the front, back, and left and right directions.

[0052] In one embodiment of the present application, a thermal insulation coating (not shown) is provided on the bottom of the battery pack 21. The thermal insulation coating can ensure that the temperature of the battery pack 21 is maintained within a controllable range, thereby improving the charge and discharge efficiency of the battery module 2.

[0053] In one embodiment of the present application, the refrigeration assembly 3 includes a refrigerator and a cooling pipe 31. One end of the cooling pipe 31 is connected to the cold end of the refrigerator to supply refrigerant in the refrigerator to the cooling pipe 31. The other end of the cooling pipe 31 contacts the battery module 2, achieving heat exchange with the battery module 2 and ensuring that the battery module 2 operates at an appropriate temperature.

[0054] In one embodiment of the present application, a heat insulating layer is provided on at least one side of the partition 4. The heat insulating layer is specifically made of thermal insulation cotton, which can isolate liquid leakage and heat insulation, thereby ensuring the safe operation of the entire cabinet.

[0055] In one embodiment of the present application, the control assembly 7 includes a high-voltage box (not shown), an inverter (not shown), a distribution box (not shown), and various auxiliary electrical components (not shown). It connects to the battery modules 2 via primary and secondary lines to provide electrical control and protection for the entire energy storage cabinet. A floor drain and flood switch are also located at the bottom of the cabinet to promptly drain water from the cabinet and provide a timely alarm to protect the entire cabinet.

[0056] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
