Description

Technical Field

[0001] The present invention relates to the field of charging piles, and in particular to an all-weather charging pile thermal management system and method. Background Art

[0002] The rapid development of the new energy vehicle industry has significantly boosted the popularity and application of charging piles, particularly in high-power fast-charging mode, which has significantly increased the frequency and power requirements of charging piles. This high-power fast-charging mode generates a significant amount of heat within the charging pile, causing the internal temperature of the device to rise sharply. Failure to implement an effective heat dissipation strategy not only compromises charging efficiency but also increases the risk of safety hazards such as thermal runaway, potentially leading to damage to the device hardware. Therefore, an effective thermal management system and methods are crucial to the safety, stability, and longevity of charging piles.

[0003] At present, the main cooling method for new energy vehicle charging piles on the market is fan-assisted cooling. Compared with natural cooling, fan-assisted cooling significantly improves cooling efficiency by enhancing air flow. Although its cooling performance is slightly inferior to that of liquid cooling systems, it has more advantages in manufacturing costs and ease of maintenance. However, in high-power fast charging scenarios, fans often have the problem of being unable to achieve rapid heat dissipation and high fan noise. The key to solving the above problems lies in further improving the cooling capacity of the charging pile, such as by optimizing the design of the heat dissipation window and expanding the blade expansion angle to promote air circulation, thereby improving the cooling capacity and appropriately reducing the fan power.

[0004] However, the above design can easily cause rainwater to penetrate into the charging pile through the heat dissipation windows on rainy days, causing safety hazards such as water immersion in the equipment and even short circuits. In addition, in sandstorms, it can easily cause a large amount of sand to flow with the air and penetrate into the charging pile through the heat dissipation windows, which can also damage the electrical components inside the pile. Sand has a certain hardness and can cause friction and wear on internal electronic components, circuit boards, etc. Long-term accumulation may cause damage to components, resulting in short circuits, open circuits and other faults, affecting the normal use of the charging pile.

DETAILED DESCRIPTION

[0018] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0019] The present invention provides an all-weather charging pile thermal management system, comprising a temperature acquisition module, an electric baffle, a foreign object sensing module and a control module. The temperature acquisition module is arranged in the charging pile to collect the real-time temperature in the pile. The electric baffle is movably connected to the heat dissipation window of the charging pile to adjust the ventilation diameter of the heat dissipation window. For example, on rainy days or sandstorms, the electric baffle can be controlled to block or partially block the heat dissipation window to reduce the ventilation diameter to avoid raindrops or sand particles from invading the pile and causing adverse consequences; or in a rainless and low-dust environment, the electric baffle can be controlled to fully open the heat dissipation window to increase the ventilation diameter and speed up the heat dissipation in the pile. The foreign object sensing module is arranged in the charging pile to monitor foreign objects that invade the interior of the charging pile and the amount of invasion per unit time, wherein the foreign objects include at least sand particles and raindrops. The foreign object sensing module can use optical sensors, capacitive sensors or resistive sensors, etc., and sensor technology that can directly identify the type of foreign object is preferred. For example, an optical sensor consists of a light source and a light receiver. When sand or raindrops pass through the sensor's detection area, they scatter or block the light, causing the intensity or pattern of the light received by the light receiver to change. By detecting this light change, it is possible to infer whether sand or raindrops have passed by, as well as information such as their size and quantity.

[0020] The control module is electrically connected to the temperature acquisition module, the foreign object sensing module, and the electric baffle. Based on the real-time temperature within the charging pile and the amount of foreign object intrusion per unit time, it controls the pivoting or sliding movement of the electric baffle to adjust the ventilation aperture of the heat dissipation window, thereby balancing the dual requirements of heat dissipation and foreign object prevention for the charging pile. Furthermore, the all-weather charging pile thermal management system also includes a fan device (not shown). This fan device is installed within the charging pile and electrically connected to the control module to respond to power commands issued by the control module. Specifically, the control module is further configured to issue power adjustment commands to the fan device based on the real-time temperature within the charging pile.

[0021] As a further improvement to the above solution, the all-weather charging pile thermal management system also includes a position determination module, electrically connected to the control module, for determining the current position information of the baffle, such as by directly measuring the baffle's inclination using an angle sensor or by using camera technology, photoelectric proximity switches, or the like for position identification, and transmitting the position information to the control module. The control module is further configured to determine the current ventilation aperture of the heat dissipation window based on the current position information. The all-weather charging pile thermal management system also includes a communication module, electrically connected to the control module and a remote server, for at least reading weather change forecast information downloaded by the remote server from a local server of the Meteorological Bureau and transmitting the weather change forecast information to the control module. The control module is further configured to plan the power strategy of the fan device for the next time period and / or the control strategy of the electric baffle for the next time period based on the weather change forecast information, the real-time temperature inside the charging pile, and the current ventilation aperture of the heat dissipation window. Generally, weather change forecast information is only downloaded for the next hour and is refreshed every 20-30 minutes to obtain new weather change forecast information. Accordingly, the control module also needs to update the weather change forecast information in real time to formulate a more accurate control strategy.

[0022] For example, if weather forecast information indicates that the area where the charging pile is located will experience rain or sandstorms within the next hour, the control module may increase the fan speed to minimize the impact of the rain or sandstorm on the cooling strategy. This will quickly reduce the temperature inside the charging pile before the rain or sandstorm arrives, effectively alleviating the awkward situation of having to open the cooling window during rain or sandstorms and accepting rain or sand intrusion due to reduced or closed ventilation apertures. For another example, if weather forecast information indicates that the area where the charging pile is located will end rain or sandstorms within the next hour, and if the cooling window is in a closed or semi-closed state, the control module may control the electric damper to temporarily partially or fully open the cooling window after one hour. If no foreign object intrusion exceeding the warning threshold is detected within the set delay period, the cooling window may be further opened. Example

[0023] This embodiment is implemented based on a pivoting electric damper, and the fan device in this embodiment has a speed gear including a high speed gear, a medium speed gear, and a low speed gear. The high speed gear corresponds to 100% of the rated speed of the fan device; the medium speed gear corresponds to 50% of the rated speed of the fan device; and the low speed gear corresponds to 20% of the rated speed of the fan device. The temperature inside the pile is divided into the first temperature zone, the second temperature zone, the third temperature zone and the fourth temperature zone; the first temperature zone is a reasonable temperature range, such as less than 50°C, and the fan device only needs to execute the low speed gear or standby; the second temperature zone is a medium temperature range such as 50-60°C. A lot of heat is generated in the pile and needs to be discharged quickly, and the fan device needs to execute the medium speed gear; the third temperature zone is a high temperature range such as 60-70°C. To avoid thermal runaway, the fan device needs to be forced to open the high speed gear, and the heat dissipation window needs to open at least part of the ventilation diameter; if the fourth temperature zone is greater than 70°C, thermal runaway is prone to occur, and the fan device needs to be forced to open the high speed gear, and the heat dissipation window needs to be forced to open to the maximum ventilation diameter, and generally it is necessary to reduce the charging and discharging power or introduce other forced cooling measures. Corresponding response measures can be taken for different meteorological environments: In rainless and low-dust weather, if the foreign object sensing module does not detect foreign object intrusion, or if it detects foreign object passage but the amount of foreign object intrusion per unit time is lower than the warning threshold (such as occasional intrusion, which needs to be eliminated), the thermal management system enters energy consumption priority mode. The control module controls the electric baffle to fully open the heat dissipation window. The control module adjusts the fan device to the corresponding speed gear or standby mode based on the real-time temperature inside the charging pile to achieve effective heat dissipation. In rainless and low-dust weather, the heat dissipation method with the lowest energy consumption is adopted to reduce energy consumption. This dynamic adjustment function improves the adaptability and economy of the charging pile. In rainy weather conditions, if the foreign object sensing module does not detect the intrusion of foreign objects, or although it detects the passage of foreign objects, the intrusion amount of foreign objects per unit time is lower than the warning threshold, it indicates that the rainfall has no obvious adverse effect on the heat dissipation demand of the charging pile. If the raindrops are affected by the wind and their falling path is difficult to extend into the heat dissipation window or are affected by the electric baffle (such as a pivotable baffle) and diverted to the periphery of the charging pile, the control module will still adjust the fan device to the corresponding speed gear or standby based on the real-time temperature in the pile to achieve effective heat dissipation; if the foreign object sensing module detects the passage of foreign objects and the intrusion amount of foreign objects per unit time is higher than the warning threshold, the control module will first control the electric baffle to pivot inward to the preset Angle, if the intrusion amount of foreign objects detected by the foreign object sensing module per unit time is still higher than the warning threshold, the control module controls the electric baffle to continue to pivot inward until the foreign object sensing module detects no foreign object intrusion, and maintains the current position state of the electric baffle. At the same time, the control module adjusts the fan device to the corresponding speed gear or standby based on the real-time temperature in the pile; in particular, if the real-time temperature in the pile is maintained in the third temperature zone for a long time under the premise that the ventilation diameter has been reduced or the temperature rises too quickly in the third temperature zone, in order to avoid thermal runaway in the pile, the control module controls the electric baffle to pivot outward to increase the ventilation diameter, and reduces the ventilation diameter again when the temperature in the pile stabilizes in the third temperature zone; In case of dust or sandstorm, if the foreign object sensing module does not detect the intrusion of foreign objects, or although it detects the passage of foreign objects, the amount of foreign objects intruding per unit time is lower than the warning threshold, it indicates that the dust or sandstorm has no obvious adverse effect on the heat dissipation demand of the charging pile. In this case, the control module will still adjust the fan device to the corresponding speed gear or standby mode based on the real-time temperature in the pile to achieve effective heat dissipation; if the foreign object sensing module detects the passage of foreign objects, and the amount of foreign objects intruding per unit time is higher than the warning threshold (if a sensing technology that can identify the type of foreign objects is used, the control module will ...) according to the real-time temperature in the pile. If the heat dissipation window is completely closed and the real-time temperature in the pile is maintained in the third temperature zone for a long time or the temperature rises too quickly in the third temperature zone, in order to avoid thermal runaway in the pile, the control module controls the electric baffle to pivot outward to increase the ventilation diameter, and reduces the ventilation diameter again when the temperature in the pile stabilizes in the third temperature zone. Example

[0024] This embodiment aims to provide a specific structure of the electric baffle 3 suitable for this application, please refer to Figure 1-5, the electric baffle 3 includes a baffle 31 rotatably connected to the heat dissipation window 2, and a driving assembly for driving the baffle 31 to pivot. Generally, there are multiple baffles 31 and they are evenly distributed along the vertical direction of the charging pile 1 to form a shutter structure. The driving assembly includes an electric cylinder 32 (a transmission device that converts electrical energy into linear motion, such as the Chinese invention patent with the announcement number CN1074820C) and a slide 34. The telescopic end of the electric cylinder 32 is fixedly connected to the slide 34, and the slide 34 is arranged on one side of the heat dissipation window 2 in a manner that can slide along the vertical direction of the charging pile 1. In this embodiment, the T-shaped slide rail 33 used in conjunction with the slide rail 34 is fixed to the inner wall of the charging pile 1, and at both ends of the T-shaped slide rail 33 are provided with limit blocks (not shown in the figure), thereby ensuring that the slide rail 34 slides reliably on the slide rail 33. The baffle 31 is provided with a limiting paddle 311 on its inner side, and a limiting slot 312 defined on its outer side. The slide bar 34 is provided with a pressure rod 341 extending through the limiting slot 312. The pressure rod 341 is directly threadedly connected to the slide bar 34, or removably attached to the slide bar 34 via screws. The telescopic end of the electric cylinder 32 drives the slide bar 34 and the pressure rod 341 fixed thereto to slide up and down along the slide rail 33. Because one end of the pressure rod 341 extends through the limiting paddle 311, the pressure rod 341's upward and downward movement slides within the limiting slot 312, thereby driving the limiting paddle 311 and the baffle 31 fixed thereto to pivot inward and outward, or up and down, about their respective rotation axes.

[0025] Based on the all-weather charging pile thermal management system provided in the above embodiments, the present invention also provides a charging pile thermal management method. Any of the all-weather charging pile thermal management systems in the above embodiments can adopt this charging pile thermal management method. Since this charging pile thermal management method adopts the all-weather charging pile thermal management system in the above embodiments, please refer to the above embodiments for the beneficial effects of the management method. Specifically, this charging pile thermal management method includes the following steps: S1. Collecting the real-time temperature of the charging pile and the amount of foreign matter intruding into the charging pile per unit time; the foreign matter includes at least sand and raindrops; S2. Based on the real-time temperature inside the pile and the amount of foreign matter intrusion per unit time, control the electric baffle to pivot or slide to adjust the current ventilation diameter of the heat dissipation window; S3, read local weather change forecast information in real time; S4. Based on the weather change forecast information, the real-time temperature inside the pile, and the current ventilation diameter of the heat dissipation window, plan the control strategy of the electric damper for the next period of time.

[0026] As a further improvement to the above solution, the all-weather charging pile thermal management system also includes a raindrop sensor and a dust sensor. The raindrop sensor is mounted on the outer wall of the charging pile and electrically connected to the control module for real-time monitoring of current rainfall conditions. The dust sensor is mounted on the outer wall of the charging pile and electrically connected to the control module for real-time monitoring of dust in the air environment. The control module is further configured to adjust the timing of the electric baffle opening the heat dissipation window based on rainfall information or dust information transmitted by the dust sensor. For example, during continuous rainfall, the electric baffle closes the heat dissipation window to prevent raindrops from intruding. If the raindrop sensor detects that the rain has stopped, the electric baffle is promptly controlled to open the heat dissipation window to accelerate heat dissipation. Without a raindrop sensor, after the heat dissipation window closes, it is either forced to open due to insufficient heat dissipation capacity or excessive temperature rise within the charging pile, or delayed based on weather forecast information, resulting in a late opening that is not conducive to heat dissipation within the charging pile.

[0027] Specifically, the foreign object sensing module can also identify other foreign objects, such as dead branches, leaves, and grass. In windy weather, these foreign objects can also be carried by the wind. If these foreign objects are detected to be continuously intruding into the charging pile, the control module should also control the electric damper to temporarily close the heat dissipation window. Since these foreign objects are moved by the wind, the electric damper should promptly open the heat dissipation window when the wind speed drops to a preset value. A wind speed sensor can also be installed on the charging pile.

[0028] Obviously, for multiple charging piles set up in the same area, the raindrop sensor and dust sensor installed outside the charging pile do not need to be installed on all charging piles. That is, only one charging pile in the charging pile group needs to be equipped with a raindrop sensor and a dust sensor, and the rainfall information and / or dust information can be shared with the other charging piles in the pile group through the automatic communication module inside the pile. Therefore, the present invention also provides a management method for an all-weather charging pile thermal management system based on a charging pile group, comprising the following steps: S100: Designate at least one charging pile in the charging pile group as a flagship pile, and the flagship pile is equipped with a raindrop sensor and a dust sensor. The remaining charging piles in the pile group can be reduced in configuration. S200: Each charging pile collects the real-time temperature inside the charging pile and the amount of foreign matter intruding into the charging pile per unit time, and controls the electric baffle of the charging pile to pivot or slide based on the real-time temperature inside the charging pile and the amount of foreign matter intruding into the charging pile per unit time to adjust the current ventilation diameter of the heat dissipation window of the charging pile; S300: Based on the rainfall information or dust information collected by the flagship charging pile, adjust the timing for the electric baffles of each charging pile in the pile group to open the heat dissipation window.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
