The electrical compartment 9 is at the rear end of the fourth partition 5, and the fire compartment 10 is at the front end of the fourth partition 5.

[0021] Specifically, the container 1 has a rectangular structure, consisting of a main beam frame, various compartment doors, and multiple wall panels (first bulkhead 2, second bulkhead 3, third bulkhead 4, and fourth bulkhead 5). The compartment doors are installed on the main beam frame of the container 1. Protective corner brackets are provided at each of the eight corners of the container 1 for protection. The first bulkhead 2, second bulkhead 3, third bulkhead 4, and fourth bulkhead 5, as well as the top layer of the container 1, are composed of inner wall panels, a fire-resistant and heat-insulating layer, and an outer wall panel, thereby improving fire-resistant and heat-insulating performance. Each compartment (liquid cooling compartment 6, battery compartment 1 7, battery compartment 2 8, electrical compartment 9, and fire compartment 10) is equipped with an independent door for opening the corresponding door individually. Each battery rack structure in battery compartment 1 7 and battery compartment 2 8 has a door at a corresponding position along the length of the enclosure 1. The first partition 2, the second partition 3, the third partition 4, and the fourth partition 5 divide the enclosure 1 into independent compartments (liquid cooling compartment 6, battery compartment 1 7, battery compartment 2 8, electrical compartment 9, and fire compartment 10), realizing functional zoning management.

[0022] Please see Figures 4-6 As shown, both battery compartment 7 and battery compartment 8 are equipped with battery rack assemblies 11. Each battery rack assembly 11 comprises a six-cluster battery rack structure, consisting of two battery rack crossbeams 110, two battery rack crossbeams 211, multiple battery rack vertical beams 112, and a battery rack base plate 115. The two battery rack crossbeams 110 are welded to the two ends of the two battery rack crossbeams 211 on opposite sides. The multiple battery rack vertical beams 112 are welded to the bottom of the connection points between the two battery rack crossbeams 110 and 211 and to the bottom of the middle section of the two battery rack crossbeams 110. The battery rack base plate 115 is welded to the bottom of the four battery rack vertical beams 112. Multiple fasteners 118 are welded to the outer periphery of the vertical beam 112. A fixed base plate 119 is welded to each pair of fasteners 118 facing each other. A fixed plate 117 is welded to the outer periphery of the vertical beam 112. The fixed plate 117 is located at the bottom of the fixed base plate 119. A battery rack reinforcing rib 113 is welded inside the vertical beam 112. A battery rack reinforcing beam 114 and a battery rack reinforcing beam 116 are welded to the bottom of the vertical beam 112. Battery modules 12 are installed on the top of the multiple fixed base plates 119. A high-voltage control box 13 is installed on the top of the fixed plate 117. The high-voltage control box 13 of each battery rack structure is placed at the bottom. A liquid cooling system is provided for each of the multiple battery modules 12.

[0023] Specifically, battery rack crossbeam 110 and battery rack crossbeam 111 are welded to form a frame structure, providing lateral support for the battery rack assembly 11. Multiple battery rack vertical beams 112 are welded at the connection points and the bottom of the middle section of battery rack crossbeam 110, forming a vertical support system together with the battery rack base plate 115, ensuring that the battery rack is stably fixed to the base of the housing 1. The fasteners 118 on the outer periphery of the battery rack vertical beams 112 are welded to the fixed base plate 119 for installing the battery module 12. The fixing plate 117 is located at the bottom of the fixed base plate 119 and is specifically used for fixing... The high-voltage control box 13 is placed at the bottom of each battery rack to facilitate cable connection to the electrical compartment 9 busbar system. The battery rack reinforcing ribs 113 inside the battery rack vertical beam 112 and the bottom battery rack reinforcing beams 114 and 116 enhance the overall deformation resistance of the battery rack and ensure the structural strength of the battery module 12 and the high-voltage control box 13 after installation. The liquid cooling system equipped with the battery module 12 is connected to the liquid cooler in the liquid cooling compartment 6 through pipelines, and the temperature control management of the battery module 12 can be achieved with the help of the battery rack structure.

[0024] Please see Figures 1-4 As shown, a liquid cooler is installed inside the liquid cooling chamber 6, and an explosion-proof fan is installed in the liquid cooling chamber 6 as the air outlet. The bottom of the fire compartment 10 is provided with an air inlet for the explosion-proof fan. Both battery compartment 1 7 and battery compartment 2 8 are equipped with explosion-proof temperature detectors, explosion-proof smoke detectors, CO gas detectors, H2 detectors and combustible gas detectors. The electrical compartment 9 is equipped with high temperature detectors and smoke detectors. The electrical compartment 9 is equipped with a combiner system, UPS, power distribution system, energy management system and battery box management unit. Multiple battery modules 12 inside each battery rack structure are interconnected with the high-voltage control box 13 inside the battery rack structure. The high-voltage control box 13 is connected to the combiner system. The liquid cooling system is connected to the liquid cooler through liquid cooling pipes passing through the first partition 2 and the second partition 3.

[0025] Specifically, the liquid cooler in the liquid cooling chamber 6 is connected to the battery modules 12 in battery compartment 7 and battery compartment 8 via stainless steel liquid cooling pipes passing through the first partition 2 and the second partition 3. This allows for the circulation of liquid coolant from the battery modules 12 to the liquid cooler, controlling the temperature of the battery modules 12. The stainless steel piping ensures corrosion resistance and system stability. Drain outlets and exhaust valves are used to discharge liquid and gas during maintenance of the liquid cooling system, ensuring normal system operation. The explosion-proof fan in the liquid cooling chamber 6 serves as the air outlet, and the explosion-proof fan inlet at the bottom of the fire compartment 10 forms a ventilation circulation, providing heat dissipation and air exchange for the equipment inside the chamber. The explosion-proof temperature detectors, explosion-proof smoke detectors, CO gas detectors, H2 detectors, and combustible gas detectors in the first battery compartment 7 and the second battery compartment 8, as well as the high-temperature detectors and smoke detectors in the electrical compartment 9, monitor the temperature, smoke, and gas concentrations in each compartment in real time. The power combiner system in the electrical compartment 9 integrates the electrical energy transmitted from each battery module 12 through the high-voltage control box 13. The UPS ensures the continuity of power supply, the power distribution system is responsible for power distribution, the energy management system optimizes energy use, and the battery box management unit monitors the battery status, together achieving comprehensive management and safety protection of the power supply.

[0026] The fire compartment 10 houses a heptafluoropropane tank and is equipped with fire-fighting piping. Fire-fighting equipment and a fire protection system are installed inside the fire compartment 10. The fire-fighting equipment is interconnected with explosion-proof heat detectors, explosion-proof smoke detectors, CO gas detectors, H2 detectors, combustible gas detectors, high-temperature detectors, and smoke detectors. The fire protection system includes detection devices, fire control devices, fire alarm devices, fire extinguishing devices, and forced control devices. The fire control devices are interconnected with the fire alarm devices, detection devices, fire extinguishing devices, and forced control devices.

[0027] Specifically, the heptafluoropropane tanks within the fire compartment 10 store extinguishing agents and are connected to battery compartment 7, battery compartment 8, and electrical compartment 9 via fire pipelines. When explosion-proof temperature detectors, explosion-proof smoke detectors, and other detection devices detect abnormal temperatures, smoke, or combustible gas concentrations, they transmit signals to the fire control device. The fire control device then activates the fire alarm device to sound an alarm and simultaneously triggers the fire extinguishing device to release heptafluoropropane for fire suppression. The forced control device is installed on the main control panel, allowing for manual intervention to start or stop the fire protection system, thus achieving automatic fire detection, alarm, fire suppression, and manual emergency control, while ensuring the safety of the power system.

[0028] The working principle of this utility model is as follows: The first partition 2, the second partition 3, the third partition 4 and the fourth partition 5 divide the housing 1 into a liquid cooling chamber 6, a battery compartment 1 7, a battery compartment 2 8, an electrical compartment 9 and a fire compartment 10. The liquid cooler in the liquid cooling chamber 6 is connected to the battery module 12 through liquid cooling pipes passing through the first partition 2 and the second partition 3. The liquid coolant flows from the battery module 12 into the liquid cooler for temperature control and then circulates back, thereby achieving temperature management of the battery module 12. The explosion-proof fan inlet at the bottom of the fire compartment 10 draws in air, and the explosion-proof fan in the liquid cooling chamber 6 serves as the air outlet to discharge air, forming a ventilation cycle. If an abnormality occurs in a certain compartment (such as the battery compartment overheating), the independent compartment design can prevent heat or faults from spreading to other compartments, ensuring that each system operates independently.

[0029] Two battery rack crossbeams 110 and 111 are welded together to form a frame. Multiple battery rack vertical beams 112 are welded to the crossbeam connections and the bottom of the middle section, forming a support system with the battery rack base plate 115. Battery modules 12 are installed on the upper part of the battery rack vertical beams 112 via a fixed base plate 119. High-voltage control boxes 13 are fixed to the bottom of the battery rack vertical beams 112 (the lowest point of each cluster) via a fixed plate 117, enabling direct cable connection between the battery modules 12 and the high-voltage control boxes 13. The high-voltage control boxes 13 are connected to the busbar system of the electrical compartment 9 via cables passing through the second partition 3 and the third partition 4, shortening the cable path. During maintenance, the battery modules 12 or the high-voltage control boxes 13 can be directly disassembled or repaired through the corresponding door of the battery rack. The battery rack reinforcing ribs 113 inside the battery rack vertical beams 112 and the bottom battery rack reinforcing beams 114 and 116 ensure structural strength, thereby improving space utilization and facilitating maintenance.

[0030] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
