[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there can be a central component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time.

[0048] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this application and in the specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this application includes any and all combinations of one or more of the related listed items.

[0049] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0050] The present application proposes an electric power system, which can be a household electric power system or an industrial electric power system, and the present application does not limit this. The electric power system includes an energy storage cabinet and electric equipment, and the energy storage component is used to provide power to the electric equipment to maintain normal use of the electric equipment.

[0051] The energy storage cabinet includes a cabinet body and batteries. The cabinet body serves as the supporting frame of the energy storage cabinet and is used to provide support and connection for other components of the energy storage cabinet. A battery compartment is formed in the cabinet body, and the battery is placed in the battery compartment. The battery is used to store and output electrical energy. During operation, the battery will inevitably release flammable gases such as hydrogen and carbon monoxide. These flammable gases will accumulate in the energy storage cabinet and may cause an explosion in severe cases. Therefore, an air handling system is usually provided in the energy storage cabinet to discharge the flammable gases in the energy storage cabinet.

[0052] Please refer to Figure 1 The air handling system 100 has an air duct 1, which is used to connect the energy storage cabinet and the external atmosphere. The air duct 1 can be formed by the cabinet body of the energy storage cabinet, or it can be a structure independent of the energy storage cabinet. The air duct 1 can be a fresh air duct or an exhaust air duct. When the air duct 1 is a fresh air duct, the air handling system 100 introduces external gas into the energy storage cabinet through the fresh air duct. When the air duct 1 is an exhaust air duct, the air handling system 100 can discharge the combustible gas in the energy storage cabinet to the outside of the atmosphere through the exhaust air duct.

[0053] In the related art, when the air handling system 100 is not working, external water vapor will also enter the energy storage cabinet along the air duct 1, increase the humidity in the energy storage cabinet, and affect the normal use of the energy storage cabinet. To solve the above problems, the present application proposes an air handling system 100, the air handling system 100 includes a shutter 2 and a fan 4, the shutter 2 is arranged in the air duct 1, the shutter 2 has a vent 23, and the vent 23 is connected to the air duct 1. The fan 4 is arranged in the air duct 1, and the fan can be an axial flow fan or a centrifugal fan, and the present application does not limit this. When the fan 4 is arranged in the fresh air channel, the fan 4 is used to blow the shutter 2 to open the vent 23 to introduce the gas inside and outside the energy storage cabinet into the energy storage cabinet. When the fan 4 is arranged in the exhaust air channel, the fan 4 is used to blow the shutter 2 to open the vent 23 to discharge the combustible gas in the energy storage cabinet to the outside. The technical solution of the present application is to set a fan 4 and a shutter 2 in the air duct 1 of the air handling system 100. When the air handling system 100 is in working state, the fan 4 blows the shutter 2 and opens the vent 23, so that the combustible gas in the energy storage cabinet can be discharged to the outside through the vent 23, or the external gas can enter the energy storage cabinet through the vent 23. When the air handling system 100 is in the closed state, the vent 23 is closed, thereby blocking the air exchange between the energy storage cabinet and the external atmosphere, delaying the time for external water vapor to enter the energy storage cabinet, and improving the stability of electrical operation in the energy storage cabinet.

[0054] There are many ways for the fan 4 to blow the shutter 2 to open the vent 23. In one embodiment of the present application, the shutter 2 is an electric shutter 2, and the air treatment system 100 further includes a wind sensor 3, which is used to monitor the wind force blowing toward the shutter 2 in real time, and transmit the monitoring data to the micro control unit, and drive the shutter 2 to open and close the vent 23 through the micro control unit. It can be understood that in this embodiment, the size of the vent 23 opened by the shutter 2 can also be set to be proportional to the wind force received by the shutter 2. When the wind force received by the shutter 2 is lower than the third threshold, the vent 23 is closed. When the wind force received by the shutter 2 exceeds the third threshold but is lower than the fourth threshold, the vent 23 is opened by 60%, so as to reduce the external water vapor and dust from entering the air treatment system 100 while discharging the combustible gas. When the wind force received by the shutter 2 exceeds the fourth threshold, the vent 23 is opened 100%, thereby discharging the combustible gas to the outside to the greatest extent.

[0055] Please refer to Figure 2 and Figure 3 In another possible implementation mode of the present application, the shutter 2 includes a window 21 and blades 22. The window 21 serves as the main body of the shutter 2 and is used to support and connect other parts of the shutter 2. The window 21 is fixed to the air duct 1, and the vent 23 runs through the window 21. The blades 22 are rotatably arranged on the window 21. The blades 22 can be provided with one, two, or three blades, and the present application does not impose any restrictions on this. The blades 22 have a closed state and an open state. In the closed state, the blades 22 cover the vent 23. In the open state, the blades 22 flip over and expose the vent 23. When the air handling system 100 is turned on, the blades 22 can flip in the horizontal direction under the blowing of the first motor, thereby exposing the vent 23, so that the combustible gas in the energy storage cabinet can be discharged outward through the vent 23. When the air handling system 100 is closed, the blades 22 will droop downward under the action of gravity, and then cover the vents 23, thereby blocking the air exchange between the energy storage cabinet and the outside, thereby delaying the humidity rise time in the energy storage cabinet and improving the stability of the operation of the electrical equipment in the energy storage cabinet. It can be understood that compared with using the wind sensor 3 to drive the vents 23 to open and close, the blades 22 have a simpler structure, lower manufacturing cost, and more convenient maintenance.

[0056] In one embodiment of the present application, the first direction is set to be up and down, and the second direction is left and right. The blades 22 are arranged in parallel along the first direction, and the blades 22 have a first end 221 and a second end 222 set along the second direction, and a third end 223 and a fourth end 224 set along the first direction. It can be understood that in order to ensure that the blades 22 can droop downward under the action of gravity, the blades 22 can be rotatably connected to the window 21 along the second direction through the third end 223, and can also be rotatably connected to the window 21 along the second direction through the fourth end 224. In this embodiment, the blades 22 are rotatably connected to the window 21 through the first end 221 and the second end 222, so as to reduce the turning distance of the blades 22 and reduce the wind resistance of the blades 22, so that the blades 22 can quickly turn over after receiving the wind to open the vents 23, and after the wind ends, they can quickly droop to close the vents 23, thereby improving the response speed of the shutter 2. In another possible implementation of the present application, the blade 22 is rotatably connected to the window 21 through the middle of the first end 221 and the second end 222 , so as to further reduce the flipping distance of the blade 22 and increase the flipping speed of the blade 22 .

[0057] In one embodiment of the present application, the air treatment system 100 further includes a sensor 3 and a circuit board assembly, and the circuit board assembly is electrically connected to the sensor 3 and the fan 4. The sensor 3 is used to detect the concentration of the combustible gas in the energy storage cabinet, and can transmit the detection result to the circuit board assembly. The sensor 3 can be a hydrogen concentration detection sensor 3, or a carbon monoxide concentration detection sensor 3, and the present application does not limit this. The sensor 3 can be arranged in the battery compartment, or at the opening of the air duct 1, and the present application does not limit this. A microcontroller unit (MCU) is arranged in the circuit board assembly, and the microcontroller unit can receive the feedback signal of the sensor 3, and selectively turn on or off the fan 4 according to the concentration of the combustible gas fed back by the sensor 3. When the concentration of the combustible gas in the energy storage cabinet reaches a preset threshold, the microcontroller unit controls the fan 4 to turn on. Specifically, the microcontroller unit of the circuit board assembly stores a preset threshold, and the value of the preset threshold can be determined by the fire protection level of the energy storage cabinet. When the fire protection level of the energy storage cabinet is required to be high, the preset threshold can be set to a low concentration, and when the fire protection level of the energy storage cabinet is required to be low, the preset threshold can be set to a high concentration. When the concentration of the combustible gas in the energy storage cabinet is lower than a preset threshold, the micro control unit controls the fan 4 to be turned off, thereby realizing automatic exhaust of the air treatment system 100 and improving the exhaust efficiency of the air treatment system 100.

[0058] In one embodiment of the present application, the preset threshold value includes a first preset threshold value and a second preset threshold value, and the second preset threshold value is greater than the first preset threshold value. When the concentration of the combustible gas in the energy storage cabinet exceeds the second threshold value, the micro control unit controls the fan 4 to rotate at full power, and when the concentration of the combustible gas in the energy storage cabinet reaches the first threshold value but does not exceed the second threshold value, the micro control unit controls the fan 4 to rotate at 60% of the full power. In this way, while controlling the air treatment system 100 to discharge gas to the outside, energy usage is saved and the energy consumption of the air treatment system 100 is reduced.

[0059] In order to ensure the stability of battery operation, low-temperature gas is usually passed through the energy storage cabinet to dissipate heat from the battery in real time. When the external air enters the energy storage cabinet through the first fresh air channel, air duct 1 and the second fresh air channel, the external high-temperature gas will merge with the low-temperature gas in the energy storage cabinet, which will cause the temperature in the energy storage cabinet to rise, affecting the working efficiency and service life of the battery. At the same time, the refrigeration system in the energy storage cabinet also needs to consume additional energy to cool the energy storage cabinet again.

[0060] To solve the above problems, in one embodiment of the present application, the air duct 1 includes a first air duct 11 and a second air duct 12, one of which is set as a fresh air duct and the other is set as an exhaust air duct. For ease of description, the first air duct 11 is set as a fresh air duct and the second air duct 12 is set as an exhaust air duct. The first air duct 11 includes a first air section 111 and a second air section 112, and the second air duct 12 includes a third air section 121 and a fourth air section 122. The air treatment system 100 also includes a full heat exchange core 5, which is arranged in the energy storage cabinet. The full heat exchange core 5 has a first flow channel 51 and a second flow channel 52, the first flow channel 51 is connected between the first air section 111 and the second air section 112, the second flow channel 52 is connected between the third air section 121 and the fourth air section 122, and the first flow channel 51 and the second flow channel 52 are interlaced in the full heat core. The high-temperature gas outside the energy storage cabinet can enter the energy storage cabinet through the first air segment 111, the first flow channel 51 and the second air segment 112, and the low-temperature combustible gas inside the energy storage cabinet can flow out to the outside atmosphere through the fourth air segment 122, the second flow channel 52 and the third air segment 121. In this process, the high-temperature gas flowing through the first flow channel 51 can exchange heat with the low-temperature combustible gas flowing through the second flow channel 52, thereby reducing the heat of the high-temperature gas, reducing the impact of the high-temperature gas outside the energy storage cabinet on the temperature inside the energy storage cabinet, reducing the energy consumption required by the energy storage cabinet refrigeration system to reduce the temperature of the high-temperature gas, and saving energy.

[0061] In one possible implementation mode of the present application, the first air section 111 is arranged opposite to the third air section 121, and the second air section 112 is arranged opposite to the fourth air section 122. In this way, the path of the high-temperature gas outside the energy storage cabinet and the low-temperature combustible gas inside the energy storage cabinet flowing through the full heat exchange core 5 is prolonged, the heat exchange time of the high-temperature gas outside the energy storage cabinet and the low-temperature combustible gas inside the energy storage cabinet is prolonged, the cooling effect of the high-temperature gas outside the energy storage cabinet is improved, the influence of the high-temperature gas on the temperature inside the energy storage cabinet is further reduced, the energy consumption required by the energy storage cabinet refrigeration system to reduce the temperature of the high-temperature gas is reduced, and energy is saved.

[0062] In one possible implementation mode of the present application, the full heat exchange core 5 is slidably disposed in the energy storage cabinet. The energy storage cabinet is provided with a second maintenance port, which is connected to the interior of the energy storage cabinet. The full heat exchange core 5 can slide out of or into the energy storage cabinet through the second maintenance port, thereby facilitating the replacement and maintenance of the full heat exchange core 5.

[0063] The air treatment system 100 also includes a filter core 6, which is disposed in the air duct 1. The filter core 6 can be disposed in the first air duct 11 or in the second air duct 12, and the present application does not limit this. The filter core 6 can be a HEPA filter core, an H filter core, or an activated carbon filter core, and the present application does not limit this. The filter core 6 can filter the air entering the energy storage cabinet, thereby reducing the impact of external dust and impurities on the electrical equipment of the energy storage cabinet.

[0064] In one embodiment of the present application, the filter core 6 is slidably disposed in the air duct 1. The air duct 1 is provided with a first maintenance port, which is connected to the air duct 1. The filter core 6 can slide out of or into the air duct 1 through the first maintenance port, so as to facilitate the replacement and maintenance of the filter core 6.

[0065] The energy storage cabinet also has a third maintenance port, which is connected to the air duct 1. The third maintenance port is used for maintenance tools to be inserted to repair the fan 4 in the air duct 1 and other electrical equipment of the air treatment system 100. In one embodiment of the present application, the air treatment system 100 also includes a maintenance cover and an access control sensor 3. The maintenance cover is covered on the third maintenance port. The access control sensor 3 is used to monitor the opening state of the maintenance cover in real time. When the maintenance cover is opened, the access control sensor 3 will actively feedback a switch signal to the micro control unit, so that the micro control unit cuts off the power supply of the air treatment system 100 to ensure the safety of electricity use of the air treatment system 100. When the maintenance cover is closed, the access control sensor 3 will actively feedback a switch signal to the micro control unit, so that the micro control unit restores the power supply of the air treatment system 100, and then the fan 4 automatically resumes normal operation.

[0066] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship of terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" are based on the orientation or positional relationship described in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0067] What is disclosed above is only a preferred embodiment of the present application, and it certainly cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiment and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
