Description

Technical Field

[0001] This utility model relates to the field of cabinet-type energy storage equipment technology, and in particular to a cabinet for an industrial and commercial energy storage system. Background Technology

[0002] Energy storage cabinets are the basic unit of energy storage equipment. They typically contain components such as battery modules, BMS, EMS, thermal management, and fire protection systems. Energy storage cabinets have wide applications in industrial and commercial sectors. For example, they can be used for peak shaving and valley filling, using intelligent control systems to detect electricity price fluctuations, storing electricity during off-peak hours and discharging during peak hours, reducing electricity costs for businesses and alleviating grid pressure. They can also serve as backup power, responding quickly to grid failures or power outages to ensure power continuity in industrial production, shopping malls, hospitals, and other locations. Furthermore, they can be used for microgrid coordination, acting as a distributed energy storage system, combined with renewable energy sources such as solar and wind power to improve microgrid stability and green electricity utilization.

[0003] In existing technologies, energy storage cabinets typically include a battery compartment, a left-side electrical compartment, and a lower electrical compartment. The battery compartment houses the battery modules, the left-side electrical compartment contains a condenser compartment for housing the condenser unit, and the electrical compartment houses the electrical components. In existing technologies, to improve cooling efficiency, the condenser unit is usually located at the top of the cabinet, while electrical components are located below the condenser compartment. During operation, water vapor in the air condenses to produce condensate, and the condenser unit is also prone to leakage. When leakage occurs, it may damage the electrical components, thus requiring improvement. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the condenser unit in the energy storage cabinet may leak liquid and damage the electrical components in the prior art, and to provide a cabinet for an industrial and commercial energy storage system.

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

[0006] A commercial and industrial energy storage system cabinet includes a cabinet with a battery compartment, a lower electrical compartment, and a left electrical compartment. The left electrical compartment is located on the left side of the cabinet, the battery compartment is located on the upper right side of the cabinet, and the lower electrical compartment is located below the battery compartment. A condensation compartment is located above the left electrical compartment, and a water collection tray is located at the bottom of the condensation compartment. The water collection tray includes a tray body and a guide edge. The guide edge is located on the rear side of the tray body. Both the tray body and the guide edge are angled downwards. Three sides of the tray body are fixedly connected to the side wall of the condensation compartment. The guide edge extends toward the rear panel of the cabinet, and a drain outlet connected to the end of the guide edge is provided on the rear panel of the cabinet.

[0007] In the above design, the top panel of the cabinet is tilted at an angle of 1-3°. This design prevents water accumulation on the top of the cabinet, extending its service life. The tilt angle and direction can be adjusted as needed; for example, the top panel can be designed to be higher at the front and lower at the back, or higher on the left and lower on the right, or vice versa, to prevent water accumulation from damaging the cabinet's electrical components.

[0008] In the above scheme, the top plate, bottom plate, left side plate, right side plate, battery compartment door and rear side plate are all made of fire-resistant board.

[0009] In the above design, a partition plate is installed on the cabinet body between the cabinet door of the left electrical compartment and the cabinet doors of the battery compartment and the lower electrical compartment. By installing the partition plate, the problem of ice forming and condensation between the cabinet doors due to insufficient gaps in cold weather, making the cabinet doors difficult to open, can be prevented.

[0010] In the above solution, the bottom of the cabinet is equipped with a fixing frame for securing the cabinet. This fixing frame design facilitates the fixation of the energy storage cabinet to the foundation or to the mounting base, making the installation of the energy storage cabinet more stable.

[0011] This invention offers several advantages: The commercial and industrial energy storage system cabinet features a condensation chamber above the left-side electrical compartment, a drip tray at the bottom of the condensation chamber, and a drain outlet at the rear of the cabinet. When leakage or condensation occurs in the condensation chamber, the water flows through the drip tray to the drain outlet, preventing damage to the electrical components below. Furthermore, the cabinet independently houses the left-side electrical compartment, battery compartment, and lower electrical compartment, each with its own dedicated door. This allows for independent maintenance of the components within each compartment without interference. The battery compartment can be configured with an IP66 protection rating, completely isolating it from the left-side and lower electrical compartments. In the event of thermal runaway or other anomalies in the battery compartment, the other two electrical compartments will not be affected, enhancing the safety of the energy storage system.
