The market has higher requirements for charging piles. At present, many charging piles are applied in outdoor scenarios. In order to achieve a faster charging speed, the charging devices in the cabinet are mainly cooled by air flow. If the heat dissipation efficiency is poor, it will lead to a low charging rate and affect the service life of the devices. For outdoor charging piles, while dissipating heat, it is also necessary to consider the use environment of rain and waterproofing to prevent rainwater from falling into the cabinet and causing circuit damage.

[0037] IPX5: IPX5 is a waterproof rating standard, indicating that the product can prevent the intrusion of water from large waves or the rapid ejection of water from a water spray hole, that is, the water column ejected from the nozzle should have no negative effect when sprayed onto the device housing from any angle.

[0038] In recent years, the market scale of electric vehicles has been continuously expanding, the rhythm of social production and life has been accelerating, and the market has higher requirements for charging piles. At present, many charging piles are applied in outdoor scenarios. In order to achieve a faster charging speed, the charging components in the cabinet are mainly cooled by air flow. If the heat dissipation efficiency is poor, it will lead to a low charging rate and also affect the service life of the components. For outdoor charging piles, while dissipating heat, it is also necessary to take into account the use environment of rain and waterproofing to avoid rainwater falling into the cabinet and causing circuit damage. At present, existing charging piles that can meet the IPX5 waterproof requirements have a complex structure of the air outlet duct and a large wind resistance, resulting in a slow air flow speed, which in turn affects the heat dissipation efficiency; while charging piles with good heat dissipation performance cannot meet the outdoor waterproof protection requirements.

[0039] To solve the above problems, the embodiments of the present application provide a control method for the charging pile louver, the louver and related devices, in order to adjust the opening and closing angles of the inner and outer louvers, so that while the inner louver ensures the air circulation inside the charging pile, the outer louver realizes reliable waterproof protection.

[0040] First, the method in the embodiments of the present application is applied to the controller of the charging pile, in combination with Figure 1 A control method for a charging pile louver in the embodiments of the present application will be described. Figure 1It is a block diagram of the functional units of a charging pile provided by an embodiment of the present application. The charging pile 100 includes a controller 110, a shutter 120, a temperature sensor 130, and a rain sensor 140. The charging pile 100 further includes an air inlet 150. The shutter 120 coincides with the position of the air outlet of the charging pile, and the shutter 120 is arranged at the air outlet. Among them, the controller 110 first detects that the charging pile 100 is in a working state, determines the temperature inside the pile of the charging pile through the temperature sensor 130, and determines the current rainfall through the rain sensor 140. Secondly, according to the temperature inside the pile and the first temperature, a heat dissipation strategy is determined. The first temperature refers to the lowest temperature at which the charging pile 100 needs to dissipate heat. Then, according to the temperature inside the pile, the first temperature, and the current rainfall, a waterproof strategy is determined. Finally, according to the heat dissipation strategy, the first opening angle of the inner louvers of the shutter 120 is adjusted, and according to the waterproof strategy, the second opening angle of the outer louvers of the shutter 120 is adjusted. The inner louvers are a louver assembly installed inside the shutter 120, and the outer louvers are a louver assembly installed outside the shutter 120.

[0041] Among them, the controller 110 is connected to the shutter 120. Specifically, the controller 110 is respectively connected to the slide bar component and the fan in the shutter 120. By controlling the slide bar component, the second opening angle of the outer louvers is controlled, and by controlling the operation of the fan, the first opening angle of the inner louvers is controlled.

[0042] Among them, after the controller 110 opens the shutter 120, the air inlet 150 is communicated with the air outlet. By opening and closing the inner louvers in the shutter 120, the flow rate of air inside the charging pile 100 is adjusted. The larger the opening angle of the inner louvers, the faster the air flow rate, and thus the better the heat dissipation effect. While ensuring heat dissipation, the controller 110 also needs to determine the opening and closing of the outer louvers in the shutter 120 based on the rainfall. It should be understood that after the inner louvers are opened, the outer louvers will also be opened and will not remain closed. The controller 110 adjusts the opening angle of the outer louvers based on the rainfall to ensure the waterproof effect. Specifically, the larger the rainfall, the smaller the opening angle of the outer louvers until the minimum angle.

[0043] Specifically, the rain sensor 140 is installed at a higher position on the top or side of the charging pile 100, so that it can better contact the rainwater and avoid being blocked by the structure of the charging pile itself or surrounding objects. Taking the optical rain sensor as an example, its working principle is that it emits light through a light-emitting diode. When raindrops pass through the light propagation path, phenomena such as refraction and scattering of light will occur, and the light intensity received by the receiver will change. According to information such as the degree and frequency of the change in light intensity, the amount of rainfall can be judged. The capacitive rain sensor detects rainfall by using the fact that raindrops falling on the surface of the sensor cause a change in capacitance, which is not limited in this embodiment.

[0044] The following combinesFigure 2 A control method for a charging pile louver in an embodiment of the present application will be described. Figure 2 It is a schematic flowchart of a control method for a charging pile louver provided by an embodiment of the present application, which specifically includes the following steps:

[0045] Step S210, when it is detected that the charging pile is in a working state, determine the temperature inside the charging pile through a temperature sensor, and determine the current rainfall through a rain sensor.

[0046] Step S220, determine a heat dissipation strategy based on the temperature inside the pile and the first temperature.

[0047] Among them, the first temperature refers to the lowest temperature at which the charging pile needs to dissipate heat. Specifically, generally, the normal operating temperature range of a charging pile is about -20°C - 55°C, and the first temperature is 55°C; for example, when the temperature inside the charging pile is greater than 55°C, the electronic components and charging modules inside the charging pile will have an increased risk of failure due to overheating, which will cause the performance of power semiconductor devices (such as IGBT - insulated gate bipolar transistor) to decline, and its on - resistance will increase with the increase of temperature, thus generating more heat and forming a vicious cycle. If the temperature is too high, it may also damage key components such as capacitors.

[0048] In a possible example, determining the heat dissipation strategy based on the temperature inside the pile and the first temperature includes: when the temperature inside the pile is less than or equal to the first temperature, determine the heat dissipation strategy as the first heat dissipation strategy, and the first heat dissipation strategy is a strategy of controlling the inner louver to close; when the temperature inside the pile is greater than the first temperature, determine the heat dissipation strategy as the second heat dissipation strategy, and the second heat dissipation strategy is a strategy of adjusting the first opening angle of the inner louver to the maximum opening angle.

[0049] Among them, when the temperature inside the pile is less than or equal to the first temperature, the charging efficiency of the charging pile will not be affected by the temperature, so there is no need to actively execute the heat dissipation strategy, and it is only necessary to keep the inner louver closed; when the temperature inside the pile is greater than the first temperature, active heat dissipation is required, and the inner louver is controlled to open to the maximum opening angle; it should be understood that the maximum opening angle is less than or equal to 90°.

[0050] Specifically, in a possible example, the louver further includes a fan, and the fan air outlet is arranged parallel to the inner louver; adjusting the first opening angle of the inner louver of the louver according to the heat dissipation strategy includes: determining the first opening angle indicated by the heat dissipation strategy; controlling the wind force of the fan according to the first opening angle to blow the inner louver to rotate and maintain the first opening angle.

[0051] Among them, the air outlet of the fan is set facing the inner louvers. By blowing air into the inner louvers through the fan, under the action of the wind pressure, all the blades of the inner louvers are opened at a certain angle, so that air enters from the air inlet of the charging pile, passes through the inner louvers, and is discharged from the air outlet of the charging pile, realizing air circulation.

[0052] Specifically, the blades of the inner louvers adopt low wind resistance blades. The low wind resistance design enables air to pass through the inner louvers more smoothly. Under the same wind pressure, a larger ventilation volume can be achieved, thus more effectively realizing the air circulation and exchange inside and outside the charging pile.

[0053] Among them, the first opening and closing angle can be the fixed maximum opening and closing angle, or the first opening and closing angle can be determined according to the current temperature inside the pile. On the basis that the temperature inside the pile is greater than the first temperature, the greater the temperature, the greater the first opening and closing angle, so as to meet the heat dissipation requirements. Further, the wind force of the fan is also controlled to be greater to maintain the first opening and closing angle until the above-mentioned maximum opening and closing angle.

[0054] It can be seen that in this example, by judging the temperature inside the pile and the first temperature, a heat dissipation strategy for the inner louvers is formulated. When the temperature inside the pile is greater than the first temperature, the opening and closing angle of the inner louvers is controlled for heat dissipation. When the temperature inside the pile is less than or equal to the first temperature, the inner louvers are kept closed, saving the overall energy consumption while ensuring the heat dissipation efficiency of the charging pile, improving the flexibility and adaptability of the louver control, ensuring the safety of the charging pile, and extending the service life.

[0055] Step S230, determine the waterproof strategy according to the temperature inside the pile, the first temperature, and the current rainfall.

[0056] In a possible example, determining the waterproof strategy according to the temperature inside the pile, the first temperature, and the current rainfall includes: when the temperature inside the pile is less than or equal to the first temperature, determining the waterproof strategy as the first waterproof strategy, and the first waterproof strategy refers to the strategy of controlling the outer louvers to close; when the temperature inside the pile is greater than the first temperature, determine the waterproof strategy according to the current rainfall, and the current rainfall is inversely proportional to the second opening and closing angle.

[0057] Among them, when the temperature inside the pile is less than or equal to the first temperature, according to the above content, the inner louvers are kept in a closed state. Therefore, the overall louver does not need to dissipate heat, and the outer louvers only need to consider waterproof protection. Therefore, the waterproof strategy is determined as the first strategy, and the outer louvers are kept closed. Without considering the heat dissipation of the charging pile, the outer louvers are completely closed to ensure the highest level of waterproof protection. Specifically, it can reach the IPX5 waterproof level.

[0058] Among them, when the temperature inside the pile is higher than the first temperature, if it is completely closed, the air cannot be discharged from the outlet of the charging pile, air circulation cannot be achieved, and the heat dissipation effect is not achieved. Therefore, at this time, the waterproof strategy needs to comprehensively consider the heat dissipation needs and determine the second opening and closing angle according to the current rainfall. The greater the current rainfall, the smaller the second opening and closing angle, but the minimum second opening and closing angle must not be less than 0°, otherwise the outer shutter will be closed.

[0059] It can be seen that in this example, the waterproof strategy is determined by judging the relationship between the temperature inside the pile and the first temperature. When the temperature inside the pile is less than or equal to the first temperature, the outer shutters are kept closed to achieve a waterproof effect. When the temperature inside the pile is greater than the first temperature, the heat dissipation demand and the current rainfall are comprehensively considered to control the outer shutters to open to the second angle. While ensuring basic heat dissipation, it prevents rainwater from entering the charging pile from the outside. By controlling the opening and closing of the outer shutters, both heat dissipation and waterproofing functions are achieved, thereby improving the adaptability and protection of the shutters to outdoor working conditions, and ensuring the safety and work efficiency of the charging pile.

[0060] In one possible example, a waterproof strategy is determined based on the current rainfall, including: determining the relationship between the current rainfall and a first rainfall, the first rainfall being the minimum rainfall that indicates that the charging pile needs to be waterproof; when the current rainfall is less than or equal to the first rainfall, determining the waterproof strategy to be the second waterproof strategy, the second waterproof strategy refers to a strategy of controlling the second opening and closing angle of the external blinds to the maximum opening and closing angle; when the current rainfall is greater than the first rainfall and less than the second rainfall, determining the waterproof strategy to be the third waterproof strategy, the third waterproof strategy refers to a strategy of adjusting the second opening and closing angle according to the current rainfall, the greater the current rainfall, the smaller the second opening and closing angle, and the first rainfall is less than the second rainfall; when the current rainfall is greater than the second rainfall, determining the waterproof strategy to be the fourth waterproof strategy, the fourth waterproof strategy refers to a strategy of controlling the second opening and closing angle to the minimum opening and closing angle.

[0061] Specifically, when the current rainfall is less than or equal to the first rainfall, the first rainfall can be, for example, 25 mm / d, indicating that the rainfall in the environment where the charging pile is located does not require targeted waterproofing operations. Therefore, the outer louvers fully serve the heat dissipation function and control the maximum opening angle of the outer louvers. It should be understood that the maximum opening angle of the outer louvers is smaller than the maximum opening angle of the inner louvers, that is, the maximum opening angle of the outer louvers is less than 90°.

[0062] Among them, the second rainfall amount is the rainfall amount associated with the external louver opening angle reaching the minimum angle. The second rainfall amount is greater than the first rainfall amount. Specifically, the second rainfall amount can be 50 mm / d. When the current rainfall amount is greater than the first rainfall amount and less than the second rainfall amount, the second opening and closing angle of the external louver is adaptively adjusted according to the size of the rainfall amount. The greater the rainfall amount, the smaller the second opening and closing angle, so as to play a waterproof role. Exemplarily, when the current rainfall amount rises from the first rainfall amount to the second rainfall amount, the second opening and closing angle gradually decreases as the rainfall amount rises, from 100% of the maximum opening and closing angle to 25% of the maximum opening and closing angle. Taking the maximum opening and closing angle as 80° as an example, the second opening and closing angle decreases from 80° to 20°.

[0063] Among them, when the current rainfall amount is greater than the second rainfall amount, it indicates that the rainfall amount is very large at this time. In order to ensure the waterproof effect, it is necessary to reduce the second opening and closing angle of the external louver. However, continuously reducing the second opening and closing angle may affect the heat dissipation effect of the charging pile. Therefore, it is selected to keep the second opening and closing angle at the minimum opening and closing angle, taking into account both the waterproof effect and the heat dissipation effect. The minimum opening and closing angle can be 25% of the above maximum opening and closing angle, or 10%, or 15%, without limitation.

[0064] It can be seen that in this example, by determining the size relationship between the current rainfall amount and the first rainfall amount, a waterproof strategy is determined to control the external louver to take into account the heat dissipation effect while ensuring the waterproof effect, and the second opening and closing angle of the external louver is determined according to the current rainfall amount, improving the environmental adaptability of the louver control, avoiding affecting the heat dissipation performance by only focusing on the waterproof effect, and meeting the outdoor waterproof and protection performance of the charging pile.

[0065] Step S240, adjust the first opening and closing angle of the internal louver of the louver according to the heat dissipation strategy, and adjust the second opening and closing angle of the external louver of the louver according to the waterproof strategy.

[0066] Among them, the internal louver is a louver component installed inside the louver, and the external louver is a louver component installed outside the louver. Specifically, the opening direction of the internal louver is the same as that of the external louver. Based on the above content, the blades of the internal louver will rotate under the wind pressure generated by the fan to maintain the first opening and closing angle; one side of the external louver faces the inside of the louver, and the other side faces the outside.

[0067] It can be seen that in this embodiment, first, it is detected that the charging pile is in a working state, the temperature inside the charging pile is determined through a temperature sensor, and the current rainfall is determined through a rain sensor; secondly, according to the temperature inside the pile and the first temperature, where the first temperature refers to the lowest temperature at which the charging pile needs heat dissipation, a heat dissipation strategy is determined; then, according to the temperature inside the pile, the first temperature, and the current rainfall, a waterproof strategy is determined; finally, according to the heat dissipation strategy, the first opening angle of the inner louvers of the louver is adjusted, and according to the waterproof strategy, the second opening angle of the outer louvers of the louver is adjusted. The inner louvers are louver components installed inside the louver, and the outer louvers are louver components installed outside the louver. In this way, heat dissipation is ensured through the inner louvers and waterproofing is ensured through the outer louvers, meeting the harsh application conditions of outdoor charging piles and improving the working efficiency and usage safety of the charging piles.

[0068] In a possible example, the louver further includes a connecting rod, the outer louver is arranged on the connecting rod, and the connecting rod is connected to the controller; adjusting the second opening angle of the outer louver of the louver according to the waterproof strategy includes: determining the second opening angle indicated by the waterproof strategy; and controlling the connecting rod to slide up and down according to the second opening angle to control the rotation of the outer louver to the second opening angle.

[0069] Specifically, the outer louver has multiple vanes, each vane is connected to a connecting rod, and multiple connecting rods are fixed on a sliding rod. The controller controls the motor of the sliding rod to control the up and down sliding of the sliding rod, thereby controlling the up and down sliding of the connecting rod, and finally realizing the opening and closing movement of the vanes of the outer louver by controlling the rotation.

[0070] In a possible example, the charging pile further includes a heater; the method further includes: determining the magnitude relationship between the temperature inside the pile and the second temperature, where the second temperature is the highest temperature characterizing that the charging pile needs heat preservation; when the temperature inside the pile is less than or equal to the second temperature, controlling the heater to start to raise the internal environment temperature of the charging pile; and controlling the inner louver and the outer louver to close.

[0071] Among them, in a low-temperature environment, the performance of electronic components inside the charging pile, such as capacitors, resistors, integrated circuits, etc., will be affected by low temperature. For example, the capacitance of a capacitor will decrease as the temperature drops, which may affect the filtering effect of the charging pile and lead to a decline in the quality of the output direct current. At the same time, low temperature may cause cold shrinkage phenomena in parts such as the pins and solder joints of electronic components, generating microcracks and increasing the contact resistance, affecting signal transmission and current flow. Specifically, the second temperature is less than the first temperature, and the second temperature can be, for example, -40°C. When the temperature inside the pile is less than or equal to the second temperature, to maintain the charging efficiency of the charging pile, it is necessary to heat up the inside of the pile, and at the same time keep the inner and outer louvers of the louver closed to ensure a closed space and improve the heating effect.

[0072] It can be seen that in this example, considering that when the temperature inside the pile is too low, it will also cause problems such as poor charging efficiency. By controlling the heater, the ambient temperature inside the charging pile is increased, and at the same time, the shutter is controlled to ensure the closure of the internal space of the charging pile, optimizing the heating and temperature-rising effect, thereby facilitating the guarantee of the charging efficiency of the charging pile.

[0073] The embodiment of the present application also provides a shutter. For details, please refer to Figure 3 and Figure 4 , Figure 3 FIG. is a schematic three-dimensional structure diagram of a shutter provided by an embodiment of the present application. Figure 4 FIG. is a schematic three-dimensional structure diagram of another shutter provided by an embodiment of the present application. The shutter is arranged at the air outlet position of the charging pile. The charging pile includes a controller connected to the shutter. The controller is used to execute any one of the above methods. The shutter 120 includes: a window body 402, and the window body 402 includes: a shutter fixing frame 501, a lower fixing frame 502, an upper fixing frame 503, and a fan fixing frame 504. The upper fixing frame 503 is installed at the top of the window body 402, the lower fixing frame 502 is installed at the bottom of the window body 402, the shutter fixing frame 501 is installed on both sides of the window body 402, and pins are provided on the shutter fixing frame 501. A plurality of shutter components are fixed to the shutter fixing frame 501 through the pins, so that the plurality of shutter components perform opening and closing movements centered on the pins. The shutter component includes: an inner shutter component 404 and an outer shutter component; a fan 403, and the fan 403 is installed on the fan fixing frame of the window body 402. The plane where the air outlet of the fan 403 is located is parallel to the fan fixing frame 504, and the fan fixing frame 504 is located at the rear end of the window body 402; the inner shutter component 404, and the inner shutter component 404 is installed inside the window body 402, and the inner side of the inner shutter component 404 faces the air outlet of the fan 403; the outer shutter component, and the outer shutter component is installed inside the window body 402 and is arranged in parallel with the inner shutter component 404. The opening and closing direction of the outer shutter component is the same as that of the inner shutter component 404; a protective net plate 401, and the protective net plate 401 is installed at the front end of the window body 402. A plurality of ventilation openings are provided on the protective net plate 401, and the plurality of ventilation openings communicate the internal space of the shutter 120 with the outside.

[0074] Specifically, in a possible example, please refer to Figure 5 and Figure 6 , Figure 5 FIG. is a schematic internal structure diagram of a shutter provided by an embodiment of the present application. Figure 6 FIG. is a schematic internal structure diagram of another shutter provided by an embodiment of the present application. The outer shutter component 406 further includes: outer shutter blades 508, a connecting rod 509, and a sliding rod 510; a plurality of outer shutter blades 508 are connected to a plurality of connecting rods 509 through pins 507; a plurality of connecting rods 509 are fixed to the sliding rod 510 through pins 507.

[0075] Specifically, the window 402 further includes a fan partition 505 for placing and separating a plurality of fans 403; the rear end of the fan 403 further includes a fan screw 405 for fixing the fan 403; the inner louver assembly 404 further includes inner louver blades 506.

[0076] Specifically, the sub-components of the outer louver assembly 406 are fixed to each other by pins. The up and down sliding movement of the sliding rod 510 is converted into the opening and closing of the outer louver blades 508 through the connecting rod 509, and the sliding rod 510 can be selected to be paired with a small servo or a small motor mechanism to achieve up and down sliding according to the actual situation.

[0077] Optionally, when applied to charging piles with different size requirements, the size of the louver 120 can be appropriately adjusted, and the specifications and quantities of the fan 403, the inner louver assembly 404, and the window 402 can be correspondingly adjusted.

[0078] Specifically, in a possible example, when the lower fixing frame 502 is installed at the bottom of the window 402, there is an angle with the plane where the bottom of the window 402 is located.

[0079] Among them, the lower fixing frame 502 can have a certain bending angle or an angle with the bottom of the window 402, so as to facilitate the drainage of accumulated water and avoid the accumulation of water falling into the louver inside at the lower fixing frame 502.

[0080] Based on the above control method of the charging pile louver, the louver provided by the embodiment of the present application can achieve: when the charging pile is in the standby state, the fan 403 stops working, and at this time, the inner louver blades 506 naturally droop under the action of gravity (as Figure 5 shown), and since there are bending edges provided on the louvers, the bending edges will block the gaps between adjacent inner louver blades 506. At this time, the outer louver blades 508 are also in the closed state under the control of the motor, and the inner and outer louver assemblies form two waterproof walls, which can specifically achieve an IPX5 protection level.

[0081] When the charging pile is working, the fan 403 is turned on and blows air on the inner louver blades 506. Under the action of the wind pressure, all the inner louver blades 506 are opened (as Figure 6 shown), and at this time, the charging pile exhausts heat to the outside through the louver 120. If water rushes towards the louver 120 from the outside at this time, the water will be blocked by the protective mesh plate 401, the inner louver assembly 404, the outer louver assembly 406, and the window 402, which can specifically achieve an IPX4 protection level.

[0082] For the control method described above, after the charging pile starts charging, when the temperature T inside the pile ≤ -40°C (second temperature): The temperature sensor and the rain sensor send signals to the controller, which controls the heater to turn on and the fan 403 to remain off. The heater heats the ambient temperature inside the charging pile; the controller controls the motor to close the outer louver blades 508. At this time, both the inner and outer louvers are in the closed state, forming an enclosed space to reduce heat dissipation.

[0083] When the temperature inside the pile, -40°C < T ≤ 55°C (T is greater than the second temperature and less than or equal to the first temperature): The temperature sensor and the rain sensor send signals to the controller, and the first heat dissipation strategy is executed to control the heater and the fan 403 to remain off. At this time, both the inner and outer louvers are in the closed state, and the charging pile generates heat continuously through the charging module and various electrical components.

[0084] When the temperature T inside the pile > 55°C (greater than the first temperature), the temperature sensor and the rain sensor send signals to the controller to determine the waterproof strategy according to the current rainfall:

[0085] If the current rainfall X ≤ 25 mm (less than or equal to the first rainfall), then the second waterproof strategy is executed, controlling the heater to remain off and the fan 403 to turn on. The inner louver blades 506 are opened under the action of the air pressure of the fan 403, driving the outer louver blades 508 to reach the maximum opening angle. Air enters the inside of the cabinet from the air inlet, passes through the charging module and various electrical components inside the cabinet in sequence for cooling, and finally discharges from between the multiple inner louver blades 506; if the current rainfall, 25 mm ≤ X < 50 mm (greater than the first rainfall and less than the second rainfall), control the inner louver blades 506 to open, and control the outer louver blades 508 to gradually decrease to 25% of the maximum opening angle according to the rainfall to reduce the water inlet area; if the current rainfall X ≥ 50 mm (greater than the second rainfall), then control the opening angle of the inner louver blades 506 to remain unchanged, and the outer louver blades 508 to remain at 25% of the maximum opening angle. At this time, the rainfall is large and waterproofing needs to be given priority. Optionally, the above temperature thresholds can be adjusted appropriately according to actual applications.
