By determining the temperature of several charging modules, the total air volume at the air inlet in the charging pile is determined, and then the speed of the charging pile fan is dynamically adjusted according to the total air volume at the air inlet. Thus, a new charging pile fan speed control strategy can be provided, so that the charging pile fan can be dynamically adjusted according to the air volume, improve the heat dissipation efficiency of the charging pile fan, reduce system noise, reduce energy consumption, and increase the operating life of the charging pile fan. Thus, the problem that the speed of the charging pile fan cannot be dynamically adjusted due to the existing charging pile fan speed control strategy, resulting in high speed, large system noise, and high energy consumption, can be solved.

[0030] In one embodiment, Figure 2 As shown, the charging pile includes two areas, namely the system area and the electrical area. Several charging modules are arranged in the system area, and several electrical equipment are arranged in the electrical area. Several charging modules are connected in parallel with each other, and the charging modules are used to convert external AC input into DC output.

[0031] The charging pile fan includes several charging module fans, system area fans and electrical area fans; several of the charging module fans correspond to several of the charging modules, and the charging module fans are arranged on the corresponding sides of the charging modules to dissipate heat for the corresponding charging modules; the system area fan is arranged in the system area to dissipate heat for the charging pile as a whole; the electrical area fan is arranged in the electrical area to dissipate heat for the electrical equipment in the electrical area.

[0032] At least one system area air inlet is provided in the system area, and the system area air inlet is an air inlet in the charging pile, and external air enters the system area through the system area air inlet, and then enters the charging pile; the system area fan is provided on the opposite side of the air inlet. Preferably, a plurality of the charging modules are provided in the central area inside the system area. Preferably, the electrical fan is provided on one side inside the electrical area, and on the same side as the setting position of the system area fan in the system area.

[0033] In this embodiment, a plurality of charging modules and system area fans are arranged in the system area, each charging module fan is arranged on the side of the charging module in a one-to-one correspondence, a plurality of electrical devices are arranged in the electrical area, and the electrical area fan is arranged in the electrical area. Thus, the charging module, the system area fan and the electrical area fan each perform their functions, dynamically adjust the speed, improve the heat dissipation efficiency, reduce the system noise, and reduce the energy consumption.

[0034] In one embodiment, Figure 3 As shown, in the step S1, determining the temperatures of the plurality of charging modules specifically includes:

[0039] In one embodiment, Figure 4 As shown, in the step S2, the total air volume of the air inlet in the charging pile is determined according to the temperatures of the charging modules.

[0040] S21. Determine a fan speed duty cycle of the charging module according to the temperatures of the charging modules and a preset system configuration, and adjust the fan speed of the charging module corresponding to the fan speed duty cycle of the charging module.

[0041] Specifically, when the temperature detected by the temperature sensor at a certain temperature monitoring point is higher than the preset target temperature, the charging module fan corresponding to the charging module where the temperature monitoring point is located is started, and the speed of the charging module fan is controlled according to the duty cycle of the charging module fan speed; when the temperature detected by the temperature sensor at the temperature monitoring point is lower than the preset target temperature, the speed of the charging module fan is reduced, and the speed of the charging module fan is controlled according to the duty cycle of the charging module fan speed.

[0042] The fan speed duty cycle of the charging module is pre-configured by the system with a preset system configuration, and the fan speed duty cycle of the charging module is controlled by a preset algorithm to achieve the purpose of precise temperature control of the corresponding charging module. For example, the preset algorithm is a PID algorithm. PID is the abbreviation of Proportional, Integral, and Differential. The PID algorithm is used to control the fan speed duty cycle of the charging module. The specific control process belongs to the prior art and will not be repeated here.

[0043] After determining the fan speed duty cycle of the charging module, the fan speed of the charging module corresponding to the fan speed duty cycle of the charging module is adjusted according to the corresponding relationship between the fan speed duty cycle of the charging module and the fan speed of the charging module.

[0044] Among them, the corresponding relationship between the charging module fan speed duty cycle and the charging module fan speed is provided by the manufacturer of the charging module fan, or, by actually measuring the charging module fan speed duty cycle and the measured value of the charging module fan, a one-to-one corresponding relationship is established between the charging module fan speed duty cycle and the charging module fan speed, thereby forming a corresponding relationship between the charging module fan speed duty cycle and the charging module fan speed. The specific method is: first set a charging module fan speed duty cycle, and measure the speed measurement value of the charging module fan corresponding to the charging module fan speed duty cycle; then set another charging module fan speed duty cycle, and measure the speed measurement value of the charging module fan corresponding to the charging module fan speed duty cycle; and so on, obtain all charging module fan speed duty cycles and their corresponding charging module fan speed measurement values, thereby obtaining the corresponding relationship between the charging module fan speed duty cycle and the charging module fan speed.

[0045] As an example, the corresponding relationship between the fan speed duty cycle of the charging module and the fan speed of the charging module is shown in Table 1 below.

[0046] Table 1 Correspondence between the fan speed duty ratio of the charging module and the fan speed of the charging module

[0047] Charging module fan speed duty cycle Charging module fan speed rpm 30％ 4500 40％ 6000 50％ 7500 60％ 9000 70％ 10500 80％ 12000 90％ 13500 100％ 15000

[0048] In this embodiment, the temperature of the key components of the charging module is detected by the temperature sensor at the temperature monitoring point, the duty cycle of the charging module fan speed corresponding to the charging module is determined, and the charging module fan speed corresponding to the duty cycle of the charging module fan speed is adjusted, so that the charging module fan is speed-regulated according to a preset algorithm (for example, a PID algorithm), ensuring that the speed of the charging module fan is the lowest under different ambient temperatures and different output powers, reducing the noise of the charging module fan, reducing the energy consumption of the charging module fan, and increasing the service life of the charging module fan.

[0049] In this embodiment, the temperature of the key components of the charging module is detected by the temperature sensor at the temperature monitoring point, the duty cycle of the charging module fan speed corresponding to the charging module is determined, and the charging module fan speed corresponding to the duty cycle of the charging module fan speed is adjusted, so that the charging module fan is speed-regulated according to a preset algorithm (for example, a PID algorithm), ensuring that the speed of the charging module fan is the lowest under different ambient temperatures and different output powers, reducing the noise of the charging module fan, reducing the energy consumption of the charging module fan, and increasing the service life of the charging module fan.

[0050] S22. According to the corresponding relationship between the fan speed duty cycle of the charging module and the air volume at the air inlet of the charging module, obtain the air volume at the air inlet of the charging module corresponding to the fan speed duty cycle of the charging module.

[0051] Specifically, the charging module is provided with a charging module air inlet, and there is a one-to-one correspondence between the air volume at the charging module air inlet and the corresponding charging module fan speed duty cycle, forming a corresponding relationship between the charging module fan speed duty cycle and the charging module air inlet air volume. Therefore, after knowing the charging module fan speed duty cycle, the charging module air inlet air volume corresponding to the charging module fan speed duty cycle can be obtained according to the corresponding relationship between the charging module fan speed duty cycle and the charging module air inlet air volume.

[0052] Optionally, the corresponding relationship between the charging module fan speed duty cycle and the charging module air inlet air volume can be determined by actually measuring the measured values ​​of the charging module fan speed duty cycle and the charging module air inlet air volume, so that the charging module air inlet air volume and its corresponding charging module fan speed duty cycle exist in a one-to-one correspondence, thereby forming a corresponding relationship between the charging module fan speed duty cycle and the charging module air inlet air volume. The specific method is: first set a charging module fan speed duty cycle, and measure the charging module air inlet air volume measurement value corresponding to the charging module fan speed duty cycle; then set another charging module fan speed duty cycle, and measure the charging module air inlet air volume measurement value corresponding to the charging module fan speed duty cycle; and so on, all charging module fan speed duty cycles and their corresponding charging module air inlet air volume measurement values ​​are obtained, thereby obtaining the corresponding relationship between the charging module fan speed duty cycle and the charging module air inlet air volume.

[0053] As an example, the corresponding relationship between the fan speed duty cycle of the charging module and the air volume of the charging module air inlet is shown in Table 2 below:

[0054] Table 2 Correspondence between the fan speed duty cycle of the charging module and the air volume at the air inlet of the charging module

[0055]

[0056]

[0057] In this embodiment, by using the correspondence between the fan speed duty cycle of the system area and the fan speed duty cycle of the charging module and the air volume at the air inlet of the charging module, the air volume at the air inlet of the charging module corresponding to the fan speed duty cycle of the charging module can be quickly obtained, so that the speed of the charging module fan can be minimized, the noise of the charging module fan can be reduced, the energy consumption of the charging module fan can be reduced, and the service life of the charging module fan can be increased; and, based on the air volume at the air inlet of a single charging module, the total air volume at the air inlet of the system area in the charging pile can be further quickly determined, so that the charging pile fan can be dynamically adjusted according to the air volume, thereby improving the heat dissipation efficiency of the charging pile fan, reducing system noise, and reducing energy consumption.

[0058] S23. Determine the total air volume at the air inlet of the system area in the charging pile according to the number of charging modules of the charging pile and the air volume at the air inlet of the charging module, wherein the total air volume at the air inlet of the system area is the total air volume at the air inlet of the charging pile.

[0059] Specifically, according to the above, a plurality of charging modules are arranged inside the system area, and each charging module is provided with a charging module air inlet. After knowing the fan speed duty cycle of the charging module, the air volume of the charging module air inlet corresponding to the fan speed duty cycle of the charging module can be obtained according to the corresponding relationship between the fan speed duty cycle of the charging module and the air volume of the air inlet of the charging module.

[0060] The system area is provided with at least one system area air inlet. In the present invention, the total air volume of the system area air inlet is equal to the product of the air volume of the charging module air inlet and the number of charging modules, that is:

[0061] Total air volume at the system inlet = number of charging modules * air volume at the charging module inlet

[0062] In this embodiment, the total air volume at the system area air inlet can be determined by the air volume at the air inlet of a single charging module and the number of charging modules. This is simple and clear, and provides a clear allocation basis for the subsequent speed regulation of the system area fan and the electrical area fan.

[0063] In one embodiment, Figure 5 As shown, in step S3, the fan speed of the charging pile is dynamically adjusted according to the total air volume at the air inlet. Specifically, it includes:

[0064] S31. Determine a fan speed duty cycle of the system area according to the total air volume at the air inlet, and dynamically adjust the fan speed of the system area according to the fan speed duty cycle of the system area.

[0065] Specifically, determine the corresponding relationship between the total air volume at the air inlet and the duty cycle of the fan speed in the system area, as well as the corresponding relationship between the fan speed duty cycle in the system area and the fan speed in the system area; determine the fan speed duty cycle in the system area according to the total air volume at the air inlet and the corresponding relationship between the total air volume at the air inlet and the fan speed duty cycle in the system area; dynamically adjust the fan speed in the system area according to the corresponding relationship between the fan speed duty cycle in the system area and the fan speed in the system area and the fan speed duty cycle in the system area.

[0066] Among them, the total air volume at the air inlet forms a one-to-one correspondence with the fan speed duty cycle of the system area, forming a corresponding relationship between the total air volume at the air inlet and the fan speed duty cycle of the system area. Therefore, after knowing the total air volume at the air inlet, the fan speed duty cycle of the system area can be obtained according to the corresponding relationship between the total air volume at the air inlet and the fan speed duty cycle of the system area.

[0067] Optionally, the correspondence between the total air volume at the air inlet and the fan speed duty cycle of the system area can be established by actually measuring the measured values ​​of the total air volume at the air inlet and the fan speed duty cycle of the system area, so that the total air volume at the air inlet and the corresponding fan speed duty cycle of the system area exist in a one-to-one correspondence, thereby forming a correspondence between the total air volume at the air inlet and the fan speed duty cycle of the system area. The specific method is: first set an air inlet total air volume, and measure the system area fan speed duty cycle measurement value corresponding to the air inlet total air volume; then set another air inlet total air volume, and measure the system area fan speed duty cycle measurement value corresponding to the air inlet total air volume; and so on, obtain all the total air volumes at the air inlets and their corresponding system area fan speed duty cycle measurement values, thereby obtaining the correspondence between the total air volume at the air inlet and the fan speed duty cycle of the system area.

[0068] As an example, the corresponding relationship between the total air volume at the air inlet and the fan speed duty cycle in the system area is shown in Table 3 below:

[0069] Table 3 Correspondence between total air volume at the air inlet and fan speed duty ratio in the system area

[0070]

[0071]

[0072] After determining the system area fan speed duty cycle, the system area fan speed corresponding to the system area fan speed duty cycle is dynamically adjusted according to the corresponding relationship between the system area fan speed duty cycle and the system area fan speed and the system area fan speed duty cycle.

[0073] Among them, the correspondence between the system area fan speed duty cycle and the system area fan speed is provided by the manufacturer of the system area fan, or, by actually measuring the system area fan speed duty cycle and the measured value of the system area fan, a one-to-one correspondence is established between the system area fan speed duty cycle and the system area fan, thereby forming a correspondence between the system area fan speed duty cycle and the system area fan speed. The specific method is: first set a system area fan speed duty cycle, and measure the speed measurement value of the system area fan corresponding to the system area fan speed duty cycle; then set another system area fan speed duty cycle, and measure the speed measurement value of the system area fan corresponding to the system area fan speed duty cycle; and so on, obtain all system area fan speed duty cycles and their corresponding system area fan speed measurement values, thereby obtaining the correspondence between the system area fan speed duty cycle and the system area fan speed.

[0074] As an example, the corresponding relationship between the system area fan speed duty cycle and the system area fan speed is shown in Table 4 below:

[0075] Table 4 Correspondence between system area fan speed duty ratio and system area fan speed

[0076]

[0077]

[0078] In this embodiment, by obtaining the system area fan speed duty cycle corresponding to the total inlet air volume based on the total inlet air volume and the correspondence between the total inlet air volume and the system area fan speed duty cycle, and then dynamically adjusting the system area fan speed based on the correspondence between the system area fan speed duty cycle and the system area fan speed, the system area fan speed is achieved, thereby realizing the coordinated speed regulation of the system area fan and the charging module fan, realizing the on-demand allocation of the total inlet air volume, dynamically adjusting the system area fan speed, and at the same time reducing the noise of the system area fan and the charging module fan, reducing the energy consumption of the system area fan and the charging module fan, and improving the service life of the system area fan and the charging module fan.

[0079] S32. Determine the duty cycle of the fan speed in the electrical area according to the duty cycle of the fan speed in the system area, and dynamically adjust the fan speed in the electrical area according to the duty cycle of the fan speed in the electrical area.

[0080] Specifically: determine the correspondence between the system area fan speed duty cycle and the electrical area fan speed duty cycle, as well as the correspondence between the electrical area fan speed duty cycle and the electrical area fan speed; determine the electrical area fan speed duty cycle based on the correspondence between the system area fan speed duty cycle and the electrical area fan speed duty cycle and the system area fan speed duty cycle; dynamically adjust the electrical area fan speed based on the correspondence between the electrical area fan speed duty cycle and the electrical area fan speed and the electrical area fan speed duty cycle.

[0081] Among them, the system area fan speed duty cycle and the electrical area fan speed duty cycle form a one-to-one correspondence, forming a corresponding relationship between the system area fan speed duty cycle and the electrical area fan speed duty cycle. Therefore, after knowing the system area fan speed duty cycle, the electrical area fan speed duty cycle can be obtained according to the corresponding relationship between the system area fan speed duty cycle and the electrical area fan speed duty cycle.

[0082] Optionally, the correspondence between the system area fan speed duty cycle and the electrical area fan speed duty cycle can be established by actually measuring the measured values ​​of the system area fan speed duty cycle and the electrical area fan speed duty cycle, so that the system area fan speed duty cycle and its corresponding electrical area fan speed duty cycle have a one-to-one correspondence, thereby forming a correspondence between the system area fan speed duty cycle and the electrical area fan speed duty cycle. The specific method is: first set a system area fan speed duty cycle, and measure the electrical area fan speed duty cycle measurement value corresponding to the system area fan speed duty cycle; then set another system area fan speed duty cycle, and measure the electrical area fan speed duty cycle measurement value corresponding to the system area fan speed duty cycle; and so on, all system area fan speed duty cycles and their corresponding electrical area fan speed duty cycle measurement values ​​are obtained, thereby obtaining the correspondence between the system area fan speed duty cycle and the electrical area fan speed duty cycle.

[0083] As an example, the corresponding relationship between the system area fan speed duty cycle and the electrical area fan speed duty cycle is shown in Table 5 below:

[0084] Table 5 Correspondence between the fan speed duty ratio of the system area and the fan speed duty ratio of the electrical area

[0085] System area fan speed duty cycle Electrical area fan speed duty cycle 10％ 30％ 20％ 40％ 30％ 50％ 40％ 60％ 50％ 70％ 60％ 80％ 75％ 95％ 90％ 100％ 100％ 100％

[0086] In the above Table 5, in the correspondence between the system area fan speed duty cycle and the electrical area fan speed duty cycle, the ratio of the electrical area fan speed duty cycle to the system area fan speed duty cycle is within a preset multiple range, and as the system area fan speed duty cycle increases, the multiple of the electrical area fan speed duty cycle to the system area fan speed duty cycle decreases, until the system area fan speed duty cycle is equal to the electrical area fan speed duty cycle. Preferably, the preset multiple range is between 1 and 3 times.

[0087] After determining the duty cycle of the electrical area fan speed, the electrical area fan speed corresponding to the electrical area fan speed duty cycle is dynamically adjusted according to the corresponding relationship between the electrical area fan speed duty cycle and the electrical area fan speed and the electrical area fan speed duty cycle.

[0088] Among them, the corresponding relationship between the electrical area fan speed duty cycle and the electrical area fan speed is provided by the manufacturer of the electrical area fan, or, by actually measuring the electrical area fan speed duty cycle and the measured value of the electrical area fan, a one-to-one correspondence is established between the electrical area fan speed duty cycle and the electrical area fan, thereby forming a corresponding relationship between the electrical area fan speed duty cycle and the electrical area fan speed. The specific method is: first set an electrical area fan speed duty cycle, and measure the speed measurement value of the electrical area fan corresponding to the electrical area fan speed duty cycle; then set another electrical area fan speed duty cycle, and measure the speed measurement value of the electrical area fan corresponding to the electrical area fan speed duty cycle; and so on, obtain all electrical area fan speed duty cycles and their corresponding electrical area fan speed measurement values, thereby obtaining the corresponding relationship between the electrical area fan speed duty cycle and the electrical area fan speed.

[0089] As an example, the corresponding relationship between the duty cycle of the fan speed in the electrical area and the fan speed in the electrical area is shown in Table 6 below:

[0090] Table 6 Correspondence between duty cycle of fan speed in electrical area and fan speed in electrical area

[0091] Electrical area fan speed duty cycle Electrical area fan speed rpm 30％ 1300 40％ 1800 50％ 2300 60％ 2700 70％ 3200 80％ 3700 95％ 4300 100％ 4600

[0092] In this embodiment, the electrical area fan speed duty cycle corresponding to the system area fan speed duty cycle is obtained according to the correspondence between the system area fan speed duty cycle and the electrical area fan speed duty cycle, and then the electrical area fan speed corresponding to the electrical area fan speed duty cycle is dynamically adjusted according to the correspondence between the electrical area fan speed duty cycle and the electrical area fan speed, thereby realizing coordinated speed regulation of the electrical area fan and the system area fan, realizing dynamic adjustment of the electrical area fan speed, and at the same time reducing the noise of the electrical area fan and the system area fan, reducing the energy consumption of the electrical area fan and the system area fan, and improving the operating life of the electrical area fan and the system area fan.
