[0034] First, let’s introduce the functions and roles of each component:

[0035] Explosion-proof box 1: Explosion-proof box 1 is the protective structure of the entire explosion-proof energy storage battery PACK box. It is used to withstand possible explosions or fires inside, prevent flames, heat and explosion fragments from spreading to the external environment, and can withstand external explosive environments, such as: Zone 1 and Zone 2 hazardous locations, and explosive gas environments of Class IIA, IIB, and IIC temperature groups T1-T4. These areas usually contain flammable and explosive gases or dust. Through the explosion-proof box 1, it is possible to provide power to electrical equipment in extremely dangerous situations, ensuring that the electrical equipment can still be used normally in such situations.

[0036] Lithium iron phosphate battery pack 5: The lithium iron phosphate battery pack 5 serves as an energy storage unit, providing a stable and reliable power supply. The lithium iron phosphate battery has high safety, long cycle life and good thermal stability, and is suitable for use in extremely dangerous environments. The lithium iron phosphate battery pack 5 is connected to the charge and discharge interface 6 and the battery BMS7 (battery management system). The charge and discharge interface 6 is an interface through which the lithium iron phosphate battery pack 5 can be charged or the electric energy in the lithium iron phosphate battery pack 5 can be supplied to electrical equipment for use.

[0037] Battery BMS7 (battery management system): responsible for monitoring the status of the lithium iron phosphate battery pack 5, including key parameters such as voltage, current, temperature, etc., to ensure that the lithium iron phosphate battery operates within a safe range, and is responsible for balancing the differences between battery cells in the lithium iron phosphate battery pack 5, optimizing battery performance, and preventing unsafe situations such as overcharging and over-discharging. The battery BMS7 is connected to the charge and discharge interface 6 and the lithium iron phosphate battery pack 5, and is also connected to the communication interface 10 to transmit data or receive control instructions.

[0038] Partition member 8: The partition member 8 is arranged inside the explosion-proof box 1 and is used to separate the interior of the shell into an upper accommodating cavity and a lower accommodating cavity. The provision of the partition member 8 helps to isolate the battery pack and the battery BMS7, reduce the mutual influence between them, and improve safety and stability.

[0039] Charge and discharge interface 6: The charge and discharge interface 6 is the connection point between the lithium iron phosphate battery pack 5 and the external power supply or load, allowing electric energy to be charged into the lithium iron phosphate battery pack 5 from the external power supply, or releasing the electric energy in the lithium iron phosphate battery pack 5 to the external load. Among them, the charge and discharge interface 6 is designed to have explosion-proof and short-circuit-proof functions, so that normal charging and discharging processes can be carried out.

[0040] Communication interface 10: Communication interface 10 is used for data communication between the battery BMS7 and external devices. Through the communication interface 10, battery status information can be transmitted in real time, remote control instructions can be received, and intelligent management and monitoring can be achieved.

[0041] The overall working principle of the equipment:

[0042] In the explosion-proof energy storage battery PACK box, the lithium iron phosphate battery pack 5 provides power supply and is connected to external devices through the charge and discharge interface 6. The battery BMS7 continuously monitors the status of the battery pack and transmits data to the external monitoring system or controller through the communication interface 10. When necessary, the battery BMS7 can trigger a protection mechanism to prevent unsafe conditions such as battery overcharging, over-discharging or overheating. The partition 8 isolates the lithium iron phosphate battery pack 5 and the battery BMS7 in different cavities to improve the safety and stability of the system. The explosion-proof box 1 provides internal and external protection to ensure safe operation even in potentially explosive environments. It is suitable for power supply needs in various hazardous locations.

[0044] In the embodiment of the present application, the lithium iron phosphate battery pack 5 serves as an energy storage unit, and its safety is of paramount importance. Therefore, specialized explosion-proof components are provided on the exterior of the lithium iron phosphate battery pack 5. These explosion-proof components may be explosion-proof valves, explosion-proof membranes, or pressure release devices, etc., which are not specifically limited here.

[0047] Series connection is to connect the positive pole of a battery cell to the negative pole of the next battery cell, and so on, to form a high-voltage battery pack, while parallel connection is to connect the positive and negative poles of the battery cells separately to form a high-capacity battery pack. These two connection methods can be selected according to actual needs to meet different voltage and capacity requirements.

[0048] Since the lithium iron phosphate battery pack 5 is detachable, it can be easily operated when the battery pack fails or needs to be replaced, reducing the difficulty and cost of maintenance. By connecting the battery cells in series or parallel, the voltage and capacity of the battery pack can be flexibly adjusted according to actual needs to meet different application scenarios.

[0049] Optionally, the partition member 8 and the explosion-proof box body 1 are connected in an integrally formed manner, and the cavity area of the upper accommodating cavity is larger than the cavity area of the lower accommodating cavity.

[0050] In the embodiment of the present application, the partition member 8 and the explosion-proof box body 1 are connected in an integrally formed manner, which means that the partition member 8 and the explosion-proof box body 1 are connected in a non-detachable manner, such as welding or integral casting molding, which is not specifically limited here, and the explosion-proof box body 1 can be separated into an upper accommodating cavity and a lower accommodating cavity by the partition member 8, and the cavity area of the upper accommodating cavity is larger than that of the lower accommodating cavity. The specific values of the cavity areas of the upper accommodating cavity and the lower accommodating cavity are not limited here and can be set according to actual conditions.

[0051] Optionally, the explosion-proof box 1 is made of aluminum alloy.

[0052] In this embodiment, the explosion-proof housing 1 is made of aluminum alloy, and its technical specifications comply with national standards GB7251, GB12476, and GB3836, as well as industry and enterprise standards. This ensures product safety and reliability. Aluminum alloy also has excellent thermal conductivity, facilitating heat dissipation in the battery system.

[0053] Optionally, a handle 2 is provided on the outside of the explosion-proof box 1, and the connection between the handle 2 and the explosion-proof box 1 is an integrally formed setting. By providing the handle 2, the explosion-proof box 1 can be easily opened or closed, and since it is an integrally formed setting, the connection is stable.

[0054] Optionally, a power switch 3 and a power indicator light 4 are provided on the explosion-proof box 1. The power indicator light 4 is provided on one side of the power switch 3, and pads 9 are provided at the four corners of the bottom of the explosion-proof box 1. The charging and discharging of the lithium iron phosphate battery pack 5 can be realized through the power switch 3, and the power indicator light 4 can indicate the charging and discharging status, which is convenient for knowing the current status of the lithium iron phosphate battery pack 5.
