[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Please refer to Figure 1 - Figure 5, the present invention provides a technical solution: an air-cooled energy storage battery cabinet, including an energy storage battery cabinet body 1, a ceiling 2 provided on the top surface of the energy storage battery cabinet body 1, and a controller 3 on one side. There are air holes 4 on the ceiling 2 to help with ventilation and ensure the air circulation inside the cabinet, cooperating with the air-cooling component to achieve a better heat dissipation effect. There is a circular opening on the top of the energy storage battery cabinet body 1, and an air-cooling component is arranged inside the annular plate 5 on the circular opening. A dust-proof net 6 is provided on the top surface of the annular plate 5. A cleaning component for cleaning the dust-proof net 6 is installed on the top of the energy storage battery cabinet body 1 through a bracket to clean the dust-proof net 6, ensuring the ventilation performance of the dust-proof net and avoiding the influence of the dust-proof net blockage on the heat dissipation effect of the air-cooling component. During long-term use, dust will gradually accumulate on the dust-proof net 6. If not cleaned in time, it will reduce the ventilation efficiency, cause the temperature inside the battery cabinet to rise, and affect the battery performance and life;

[0043] An energy storage battery cabinet body 1 is provided with a BMS system, and a temperature regulation component and a humidity regulation component are provided for supporting the BMS system; the BMS system is electrically connected to the controller 3. Among them, the BMS system, that is, the Battery Management System, is a mature existing technology and will not be elaborated in this application. It is the core management component of the entire battery cabinet. The BMS system can monitor the status information of the battery in real time, such as the voltage, current, temperature, state of charge (SOC), and state of health (SOH) of the battery, etc., providing data support for the humidity-temperature collaborative control module to ensure the accurate grasp of the battery status, so as to achieve the effective protection and management of the battery; through the cooperation of the temperature regulation component and the humidity regulation component with the BMS system, they work according to the instructions of the humidity-temperature collaborative control module; the temperature regulation component is used to adjust the temperature inside the battery cabinet, cooling down when the battery temperature is too high and heating up when the temperature is too low to ensure that the battery is always in an appropriate working temperature range; the humidity regulation component is responsible for controlling the humidity inside the cabinet to avoid problems such as battery corrosion caused by too high humidity and electrostatic hazards caused by too low humidity;

[0044] The controller 3 includes a dust-proof cleaning control module and a humidity-temperature collaborative control module;

[0045] The dust-proof cleaning control module monitors the blockage state of the dust-proof net 6, analyzes the blockage state information of the dust-proof net 6 to obtain the blockage analysis situation, and then controls the operation of the cleaning component; by monitoring data such as the air pressure difference on both sides of the dust-proof net 6, analyzing the blockage state information of the dust-proof net 6 to obtain the blockage analysis situation, and according to different blockage degrees, controlling the operation of the cleaning component to achieve the automatic cleaning of the dust-proof net. The work of this module is crucial for maintaining the normal ventilation and heat dissipation of the air-cooling component, directly affecting the heat dissipation efficiency and overall performance of the battery cabinet;

[0046] The humidity-temperature coordinated control module is used to obtain the status information of the batteries in the energy storage battery cabinet body 1 through the BMS system, and obtain the temperature and humidity conditions in the energy storage battery cabinet body 1. By analyzing the status information of the batteries and the temperature and humidity conditions in the cabinet, it controls the operation of relevant components. It should be noted that the humidity-temperature coordinated control module comprehensively analyzes the battery status information obtained through the BMS system, as well as the temperature and humidity conditions in the cabinet collected by the temperature sensor and humidity sensor. Through complex algorithms and logical judgments, it formulates a reasonable regulation strategy, and then controls the operation of the temperature regulation component and the humidity regulation component to achieve precise regulation of the temperature and humidity environment in the battery cabinet, provide a stable operating environment for the batteries, and ensure the safety and stability of the batteries.

[0047] It should be noted that through the coordinated operation of the dust-proof cleaning control module and the humidity-temperature coordinated control module, although their functions are different, they are interrelated. The clogging condition of the dust-proof net will affect the ventilation and heat dissipation effect, and thus affect the temperature and humidity distribution in the battery cabinet; while the regulation of temperature and humidity by the humidity-temperature coordinated control module will affect the operating state of the batteries and indirectly affect the clogging speed of the dust-proof net (for example, too high temperature may cause the internal gas of the batteries to expand, increasing the dust adsorption amount). The two modules work together to ensure the stable operation of the battery cabinet.

[0048] In this application, the cleaning component includes a micro motor 7 and a dust cleaning brush 8; the micro motor 7 is installed on the bracket at the top of the energy storage battery cabinet body 1, and the output shaft of the micro motor 7 is connected to the dust cleaning brush 8 of the dust-proof net 6.

The formula is expressed as: P = P1×p1 + P2×p2 + P3×p3; where p1, p2, and p3 respectively represent the weights corresponding to the air pressure difference, the influence value of the non-ash-cleaned area without ash cleaning, and the deposited air pressure difference.

[0055] Set a group of clogging state ranges, including a slight clogging state, a moderate clogging state, and a severe clogging state; match the value range of the clogging state range group with the pressure difference to determine the clogging state of the dust-proof net 6: If the dust-proof net 6 is within the value range of the slight clogging state, record the data without triggering cleaning; If the dust-proof net 6 is within the value range of the moderate clogging state, start the operation of the ash cleaning component according to the set regular cleaning cycle; If the dust-proof net 6 is within the value range of the severe clogging state, immediately trigger the start of the cleaning component and reset the cleaning cycle.

[0056] Mark the air pressure difference, the influence value of the non-ash-cleaned area without ash cleaning, the deposited air pressure difference, the pressure difference, and the clogging state of the dust-proof net 6 as the clogging analysis situation.
