The ceiling 2 is provided with air holes 4 to facilitate ventilation and ensure air circulation in the cabinet, and cooperate with the air cooling component to achieve a better heat dissipation effect. A circular opening is opened on the top of the energy storage battery cabinet body 1, and an air cooling component is arranged in an annular plate 5 on the circular opening. A dustproof net 6 is arranged on the top surface of the annular plate 5. A cleaning component for cleaning the dustproof net 6 is installed on the top of the energy storage battery cabinet body 1 through a bracket. The cleaning component is used to clean the dustproof net 6 to ensure the ventilation performance of the dustproof net and avoid affecting the heat dissipation effect of the air cooling component due to the blockage of the dustproof net. During long-term use, dust will gradually accumulate on the dustproof net 6. If it is not cleaned in time, the ventilation efficiency will be reduced, resulting in an increase in the temperature in the battery cabinet, affecting the battery performance and life; The energy storage battery cabinet body 1 is provided with a BMS system, and is provided with a temperature regulating component and a humidity regulating component used in conjunction with the BMS system; the BMS system is electrically connected to the controller 3, wherein the BMS system, namely the battery management system (Battery Management System), is an existing mature technology, and is not described in detail in this application, and is the core management component of the entire battery cabinet; the BMS system can monitor the battery status information in real time, such as the battery voltage, current, temperature, state of charge (SOC) and state of health (SOH), etc., and provide data support for the humidity-temperature collaborative control module to ensure accurate grasp of the battery status, thereby achieving effective protection and management of the battery; the temperature regulating component and the humidity regulating component are used in conjunction with the BMS system and work according to the instructions of the humidity-temperature collaborative control module; the temperature regulating component is used to adjust the temperature in 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 a suitable operating temperature range; the humidity regulating component is responsible for controlling the humidity in the cabinet to avoid problems such as battery corrosion caused by excessive humidity and static electricity hazards caused by excessive humidity; The controller 3 includes a dust-proof cleaning control module and a humidity-temperature coordinated control module; The dust cleaning control module monitors the clogging state of the dust net 6, analyzes the clogging state information of the dust net 6 to obtain the clogging analysis situation, and then controls the operation of the cleaning component; by monitoring the air pressure difference on both sides of the dust net 6 and other data, analyzes the clogging state information of the dust net 6, obtains the clogging analysis situation, and controls the operation of the cleaning component according to different clogging degrees to realize automatic cleaning of the dust net. The work of this module is crucial to maintaining the normal ventilation and heat dissipation of the air-cooled component, and directly affects the heat dissipation efficiency and overall performance of the battery cabinet; The humidity-temperature collaborative control module is used to obtain the status information of the battery 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, and control the operation of related components by analyzing the battery status information and the temperature and humidity conditions in the cabinet; it should be noted that the humidity-temperature collaborative control module uses the battery status information obtained by the BMS system, as well as the temperature and humidity conditions in the cabinet collected by the temperature sensor and the humidity sensor, to conduct a comprehensive analysis, and through complex algorithms and logical judgments, formulate a reasonable control strategy, and then control the operation of the temperature control component and the humidity control component, to achieve precise control of the temperature and humidity environment in the battery cabinet, provide a stable operating environment for the battery, and ensure the safety and stability of the battery.
