Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more specifically to a heat dissipation method, device, system, vehicle, and readable storage medium. Background Technology

[0002] With the development of the automotive industry, more and more vehicles are equipped with wireless charging capabilities. For example, wireless charging capabilities can include both high-power and low-power wireless charging. When a vehicle uses high-power wireless charging to wirelessly charge a device, it generates a significant amount of heat, affecting the charging efficiency of the device.

[0003] To prevent excessive heat from affecting the charging efficiency of the terminal device, vehicles can control cooling fans to dissipate heat from the charging area. However, cooling fans are quite noisy when operating at high power, and ineffective at dissipating heat from the charging area when operating at low power. Therefore, how to reduce the noise impact of the cooling fan while ensuring effective heat dissipation of the charging area is a pressing technical problem that needs to be solved. Summary of the Invention

[0004] One of the objectives of this invention is to provide a heat dissipation method, apparatus, system, vehicle, and readable storage medium to ensure heat dissipation of the charging area while reducing the noise impact of the cooling fan.

[0005] According to a first aspect of this application, a heat dissipation method is provided, applied to a controller in a vehicle's heat dissipation system. The heat dissipation system further includes a wireless charging device. The wireless charging device is provided with a first fan, a second fan, a first air vent, and a second air vent. The first fan is connected to the first air vent, and the second fan is connected to the second air vent. The first fan is used to blow airflow into the charging area of ​​the wireless charging device, and the second fan is used to exhaust airflow from the charging area of ​​the wireless charging device. The method includes: determining that the wireless charging device is in a power supply state; controlling the first fan to be in an on state when the power supply power of the wireless charging device is greater than or equal to a preset power supply threshold; controlling the first fan to be in a off state when the power supply power of the wireless charging device is less than the preset power supply threshold; and controlling the second fan to be in an on state.

[0006] Based on the aforementioned technical means, when the wireless charging device is determined to be in a powered state, if the power supply of the wireless charging device is greater than or equal to a preset power supply threshold, the first fan is controlled to be turned on. Since the charging area is hotter when the power supply is greater than or equal to the preset power supply threshold, turning on the first fan can bring fresh air into the charging area, effectively dissipating heat. When the power supply of the wireless charging device is less than the preset power supply threshold, the charging area is cooler; turning off the first fan and turning on the second fan can remove the heat from the charging area, and the second fan is quieter. Thus, dynamically adjusting the on / off state of the first and second fans under different power supply levels can reduce the noise impact of the cooling fans while ensuring effective heat dissipation of the charging area.

[0007] Furthermore, after controlling the first fan to be in the on state, the method further includes: determining the vehicle speed, the on / off state of the vehicle air conditioner, and the on / off state of the vehicle media player; and controlling the second fan to be in the on state when the vehicle meets any one of a plurality of preset conditions; the plurality of preset conditions include a first preset condition, a second preset condition, and a third preset condition, wherein the first preset condition is that the vehicle speed is greater than or equal to a vehicle speed threshold, the second preset condition is that the on / off state of the vehicle air conditioner, and the third preset condition is that the on / off state of the vehicle media player.

[0008] Based on the aforementioned technical means, after controlling the first fan to be on, if the vehicle speed is greater than or equal to a vehicle speed threshold, or the vehicle air conditioning or vehicle media player is on, the controller can then control the second fan to be on. At this time, with both the first and second fans on simultaneously, the airflow speed in the charging area can be accelerated, thereby improving the heat dissipation effect. Furthermore, because the vehicle speed is greater than or equal to the vehicle speed threshold, or the vehicle air conditioning or vehicle media player is on, the noise from the vehicle driving, the air conditioning, or the media player can partially mask the fan noise, thus reducing the noise impact of the cooling fans.

[0009] Furthermore, the method also includes: controlling the first fan and the second fan to be in a turned-off state when the wireless charging device is in a power-off state.

[0010] Based on the above technical means, when the wireless charging device is in a state of power outage, the first fan and the second fan are controlled to be in a state of shutdown, which can save vehicle power resources and reduce the noise impact of the cooling fan.

[0011] Furthermore, determining that the wireless charging device is in a power supply state includes: determining that the wireless charging device is in a power supply state when it is detected that the wireless charging device is connected to the power-consuming device and the power-consuming device has wireless charging function.

[0012] Based on the above technical means, when it is determined that the wireless charging device is in a power supply state, the on-state of the first fan and the second fan can be controlled according to the power supply power of the wireless charging device. This can avoid the controller frequently detecting the power supply power of the wireless charging device and reduce the controller's resource occupancy.

[0013] Secondly, a heat dissipation device is provided, which is applied to a controller in a vehicle's heat dissipation system. The heat dissipation system also includes a wireless charging device, a first fan, and a second fan. The wireless charging device is provided with a first air vent and a second air vent. The first fan is connected to the first air vent, and the second fan is connected to the second air vent. The first fan is used to blow airflow into the charging area of ​​the wireless charging device, and the second fan is used to exhaust airflow from the charging area of ​​the wireless charging device. The device includes: a determining unit and a controlling unit. The determining unit is used to determine that the wireless charging device is in a power supply state. The controlling unit is used to control the first fan to be in an on state when the power supply power of the wireless charging device is greater than or equal to a preset power supply threshold. The controlling unit is also used to control the first fan to be in an off state when the power supply power of the wireless charging device is less than the preset power supply threshold, and to control the second fan to be in an on state.

[0014] Furthermore, the determining unit is also used to determine the vehicle speed, the on / off status of the vehicle air conditioning, and the on / off status of the vehicle media player; the control unit is also used to control the second fan to be turned on when the vehicle meets any one of a plurality of preset conditions; the plurality of preset conditions include a first preset condition, a second preset condition, and a third preset condition, wherein the first preset condition is that the vehicle speed is greater than or equal to a vehicle speed threshold, the second preset condition is that the on / off status of the vehicle air conditioning is on, and the third preset condition is that the on / off status of the vehicle media player is on.

[0015] Furthermore, the control unit is also used to: control the first fan and the second fan to be in a closed state when the wireless charging device is in a power-off state.

[0016] Furthermore, the determining unit is specifically used to: determine that the wireless charging device is in a power supply state when it is detected that the wireless charging device is connected to the power-consuming device and the power-consuming device has wireless charging function.

[0017] Thirdly, a heat dissipation system is provided, the heat dissipation system including a controller for performing methods as described in the first aspect or any possible design of the first aspect.

[0018] Fourthly, a heat dissipation device is provided, comprising: a processor; a memory for storing processor-executable instructions; the processor being configured to execute instructions, functions performed in the first aspect or any possible design of the first aspect.

[0019] Fifthly, a vehicle is provided, including the cooling system provided in the third aspect.

[0020] In a sixth aspect, a heat dissipation device is provided, which can realize the functions performed by the heat dissipation device in the above aspects or possible designs. The functions can be implemented by hardware. For example, in one possible design, the heat dissipation device may include a processor and a communication interface. The processor can be used to support the heat dissipation device in realizing the functions involved in the first aspect or any possible design of the first aspect.

[0021] In another possible design, the heat dissipation device may also include a memory for storing necessary computer execution instructions and data. When the heat dissipation device is in operation, the processor executes the computer execution instructions stored in the memory to cause the heat dissipation device to perform the first aspect or any of the possible heat dissipation methods described above.

[0022] In a seventh aspect, a computer-readable storage medium is provided, which may be a readable non-volatile storage medium storing computer instructions or programs that, when executed on a computer, enable the computer to perform the first aspect or any of the possible heat dissipation methods described above.

[0023] Eighthly, a computer program product containing instructions is provided, which, when run on a computer, enables the computer to perform the heat dissipation method of the first aspect or any possible design of the above aspects.

[0024] The beneficial effects of this invention are:

[0025] (1) When the wireless charging device is determined to be in a powered state, if the power supply of the wireless charging device is greater than or equal to a preset power supply threshold, the first fan is controlled to be turned on. Since the charging area is hotter when the power supply is greater than or equal to the preset power supply threshold, turning on the first fan can bring fresh air into the charging area, effectively dissipating heat from the charging area. When the power supply of the wireless charging device is less than the preset power supply threshold, the charging area is cooler. Turning off the first fan and turning on the second fan can remove the heat from the charging area, and the second fan is quieter. In this way, by dynamically adjusting the on / off state of the first and second fans under different power supply levels, the noise impact of the cooling fans can be reduced while ensuring the heat dissipation effect on the charging area.

[0026] (2) After controlling the first fan to be on, if the vehicle speed is greater than or equal to the vehicle speed threshold, or the vehicle air conditioning switch is on, or the vehicle media player switch is on, the controller can then control the second fan to be on. At this time, the first and second fans are on simultaneously, which can accelerate the air circulation speed in the charging area, thereby improving the heat dissipation effect on the charging area. Furthermore, since the vehicle speed is greater than or equal to the vehicle speed threshold, or the vehicle air conditioning switch is on, or the vehicle media player switch is on, the sound of the vehicle driving, the sound of the vehicle air conditioning working, or the sound of the vehicle media player can cover part of the fan noise, thereby reducing the noise impact of the cooling fan.

[0027] (3) When the wireless charging device is in a state of power outage, the first fan and the second fan are controlled to be in a state of shutdown, which can save vehicle power resources and reduce the noise impact of the cooling fan.

[0028] (4) When it is determined that the wireless charging device is in a power supply state, the opening status of the first fan and the second fan is controlled according to the power supply power of the wireless charging device. This can avoid the controller frequently detecting the power supply power of the wireless charging device and reduce the resource occupancy rate of the controller.

[0042] With the development of the automotive industry, more and more vehicles are equipped with wireless charging capabilities. For example, wireless charging capabilities can include both high-power and low-power wireless charging. When a vehicle uses high-power wireless charging to wirelessly charge a device, it generates a significant amount of heat, affecting the charging efficiency of the device.

[0043] To prevent excessive heat from affecting the charging efficiency of the terminal device, vehicles can control cooling fans to dissipate heat from the charging area. However, cooling fans are quite noisy when operating at high power, and ineffective at dissipating heat from the charging area when operating at low power. Therefore, how to reduce the noise impact of the cooling fan while ensuring effective heat dissipation of the charging area is a pressing technical problem that needs to be solved.

[0044] In view of this, embodiments of this application provide a heat dissipation method applied to a controller in a vehicle's heat dissipation system. The heat dissipation system further includes a wireless charging device. The wireless charging device is provided with a first fan, a second fan, a first air vent, and a second air vent. The first fan is connected to the first air vent, and the second fan is connected to the second air vent. The method includes: determining that the wireless charging device is in a power supply state; controlling the first fan to be turned on when the power supply power of the wireless charging device is greater than or equal to a preset power supply threshold; and controlling the second fan to be turned on when the power supply power of the wireless charging device is less than the preset power supply threshold.

[0045] The methods provided in the embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0046] It should be noted that the heat dissipation system described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and does not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of heat dissipation systems and the emergence of other heat dissipation systems, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0047] The cooling system provided in this application can be applied to vehicles. The vehicle can be any type of vehicle. For example, the vehicle can be a gasoline vehicle, a hybrid vehicle, a new energy vehicle, etc. The embodiments of this application do not limit the specific technology, quantity, or form of equipment used in the vehicle.

[0048] Figure 1 This is a schematic diagram of the composition of a heat dissipation system 10 provided in an embodiment of this application, as shown below. Figure 1 As shown, the heat dissipation system 10 may include a controller 11 and a wireless charging device 12.

[0049] The controller 11 is connected to the wireless charging device 12. For example, the controller 11 and the wireless charging device 12 can be connected wirelessly or wiredly, and this embodiment of the invention does not limit the connection.

[0050] The controller 11 can be used to control the first fan (also known as the main fan, blowing fan, etc.) and the second fan (also known as the auxiliary fan, suction fan, etc.) to be on or off according to the power supply of the wireless charging device, when it is determined that the wireless charging device is in a powered state. The controller 11 can be installed inside the vehicle. Alternatively, the controller 11 can be any electronic device with data processing capabilities.

[0051] The wireless charging device 12 can be used to wirelessly charge electrical devices.

[0052] Figure 2 This is a top view of a wireless charging device 12 provided in an embodiment of this application. Figure 3 This is a bottom view of a wireless charging device 12 provided in an embodiment of this application. Figure 2 and Figure 3 As shown, the wireless charging device 12 may include a first fan 121, a second fan 122, a first air vent 123, and a second air vent 124, and may also include a near field communication (NFC) circuit board 125, a wireless charging upper cover 126, a wireless charging lower cover 127, and a plug port 128, etc.

[0053] The first fan 121 is connected to the first air vent 123, and the second fan 122 is connected to the second air vent 124. The first fan 121 and the second fan 122 are arranged side-by-side in the central part of the lower cover 127 of the wireless charging device. The first fan 121 blows airflow into the charging area of ​​the wireless charging device through the first air vent 123, and the second fan 122 exhausts the airflow from the charging area of ​​the wireless charging device through the second air vent 124. This increases airflow in the charging area and ensures effective heat dissipation.

[0055] The NFC circuit board 125 supplies power to the device when it senses a connected device.

Figure 1 The names of the modules included are unrestricted, and except for Figure 1 In addition to the functional modules shown, other modules may also be included, but this application embodiment does not limit this.

[0057] In practical implementation, Figure 1 The controller in the middle can be adopted Figure 4 The shown composition structure, or including Figure 4 The components shown. Figure 4 This is a schematic diagram of a heat dissipation device 200 provided in an embodiment of this application. The heat dissipation device 200 can be a controller in a heat dissipation system, or it can be a chip or system-on-a-chip in the controller. Figure 4As shown, the heat dissipation device 200 includes a processor 201, a communication interface 202, and a communication line 203.

[0058] Furthermore, the heat dissipation device 200 may also include a memory 204. The processor 201, the memory 204, and the communication interface 202 can be connected via a communication line 203.

[0060] Communication interface 202 is used to communicate with other devices or other communication networks. Communication interface 202 can be a module, circuit, communication interface, or any device capable of enabling communication.

[0061] Communication line 203 is used to transmit information between the various components included in the heat dissipation device 200.

[0062] Memory 204 is used to store instructions executable by processor 201. These instructions may be computer programs.

The message names or parameter names in the messages exchanged between the various devices in the embodiments of this application are merely examples, and other names may be used in specific implementations without limitation.

[0070] The following is combined Figure 1 The heat dissipation system shown herein describes the heat dissipation method provided in the embodiments of this application.

[0071] This application uses an example of a controller for illustration, such as... Figure 5 As shown, the method includes the following steps S301-S304:

[0072] S301, The controller determines that the wireless charging device is in a powered state.

[0073] The wireless charging device can be fixed to the vehicle's center console. For example, the wireless charging device can be a wireless charger.

[0074] As one possible implementation, the controller can determine that the wireless charging device is in a powered state upon detecting that it has been connected to a device. For example, after the wireless charging device is connected to the device, it generates a low-potential signal and sends it to the controller via a hardwired loop. Accordingly, the controller can determine that the wireless charging device is connected to the device upon receiving the low-potential signal, and thus determine that the wireless charging device is in a powered state.

[0075] As another possible implementation, the heat dissipation system also includes a central control display device connected to the controller; the central control display device is equipped with a soft switch, and the controller can also determine whether the wireless charging device is in a power supply state based on the state of the soft switch.

[0076] A soft switch is used to control the power supply status of a wireless charging device. For example, when the soft switch is in the on state, the wireless charging device is powered on. If the user clicks the soft switch, the soft switch switches from the on state to the off state, and at the same time, the controller switches the wireless charging device from the powered state to the power-off state.

[0077] For example, when the soft switch is in the off state, the wireless charging device is in the power-off state. If the user clicks the soft switch, the soft switch switches from the off state to the on state. At the same time, the controller switches the wireless charging device from the power-off state to the discharge state.

[0078] In this way, the controller can also determine that the wireless charging device is in a power supply state when it detects that the wireless charging device is connected to the power-consuming device and the soft switch is in the open state.

[0079] Understandably, by using the soft switch set within the power supply control system IP, the power supply status of the wireless charging device can be flexibly controlled according to user needs.

[0080] It should be noted that the device being charged can be any device that can be charged or powered by a wireless charging device. In other words, the device must have wireless charging capability. For example, this could be a terminal device, a tablet computer, etc.

[0081] S302, The controller determines whether the power supply of the wireless charging device is greater than or equal to the preset power supply threshold.

[0082] The preset power supply threshold can be set as needed. For example, it can be 10 watts, 15 watts, 20 watts, etc.

[0083] As one possible implementation, the controller can obtain the power supply signal from the wireless charging device and determine whether the power supply of the wireless charging device is greater than or equal to a preset power supply threshold based on the power supply signal.

[0084] The power supply signal is used to indicate whether the power supply power of the wireless charging device is greater than or equal to a preset power supply threshold. The power supply signal includes a first power supply signal and a second power supply signal. The first power supply signal indicates that the power supply power of the wireless charging device is greater than or equal to the preset power supply threshold, and the second power supply signal indicates that the power supply power of the wireless charging device is less than the preset power supply threshold.

[0085] When the controller determines that the power supply signal is the first power supply signal, it determines that the power supply power of the wireless charging device is greater than or equal to the preset power supply threshold (also known as high power supply); when the controller determines that the power supply signal is the second power supply signal, it determines that the power supply power of the wireless charging device is less than the preset power supply threshold (also known as low power supply).

[0086] In practical applications, the first power supply signal can be WLCM_WirelessHighCharging_Status = 0x1, and the second power supply signal can be WLCM_WirelessCharging_Status = 0x1.

[0087] When the wireless charging device stops high-power charging, WLCM_WirelessHighCharging_Status = 0x0; when the wireless charging device stops low-power charging, WLCM_WirelessCharging_Status = 0x0.

[0088] S303. When the power supply of the wireless charging device is greater than or equal to the preset power supply threshold, the controller controls the first fan to be turned on.

[0089] The first fan is used to blow airflow onto the charging area of ​​the wireless charging device.

[0090] As one possible implementation, when the first fan switch is in the off state, the controller can switch the first fan switch from the off state to the closed state to control the first fan to be in the on state. When the first fan switch is in the closed state, the controller can control the first fan switch to remain in the closed state to control the first fan to be in the on state.

[0091] In practical applications, the controller can determine the on / off state of the first fan through the first fan signal. The first fan signal can be WLCM_Wireless_Mainfan. If the first fan is on, then WLCM_Wireless_Mainfan = 0x1; if the cooling fan is off, then WLCM_Wireless_Mainfan = 0x0.

[0092] S304. When the power supply of the wireless charging device is less than a preset power supply threshold, the controller controls the first fan to be in a closed state and controls the second fan to be in a closed state.

[0093] The second fan is used to exhaust airflow from the charging area of ​​the wireless charging device.

[0094] As one possible implementation, when the switch of the first fan is in the closed state, the controller can switch the switch of the first fan from the closed state to the open state to control the first fan to be in the off state. When the switch of the first fan is in the open state, the controller can control the switch of the first fan to remain in the open state to control the first fan to be in the off state.

[0095] When the second fan switch is in the off state, the controller can switch the second fan switch from the off state to the closed state to control the second fan to be in the on state. When the second fan switch is in the closed state, the controller can control the second fan switch to remain in the closed state to control the second fan to be in the on state.

[0096] In practical applications, the controller can determine the on / off status of the second fan through the second fan signal. The second fan signal can be WLCM_Wireless_Supfan. If the second fan is on, WLCM_Wireless_Supfan = 0x1; if the suction cooling fan is off, WLCM_Wireless_Supfan = 0x0.

[0097] Based on the technical solution provided in this application, when the wireless charging device is determined to be in a powered state, if the power supply of the wireless charging device is greater than or equal to a preset power supply threshold, the first fan is controlled to be turned on. Since the charging area is hotter when the power supply is greater than or equal to the preset power supply threshold, turning on the first fan can bring fresh air into the charging area, effectively dissipating heat. When the power supply of the wireless charging device is less than the preset power supply threshold, the charging area is cooler, so turning off the first fan and turning on the second fan can remove the heat from the charging area, and the second fan is quieter. Thus, by dynamically adjusting the on / off states of the first and second fans under different power supply levels, the noise impact of the cooling fans can be reduced while ensuring effective heat dissipation of the charging area.

[0098] In some embodiments, such as Figure 6 As shown, in order to further reduce the noise impact of the cooling fan while ensuring the heat dissipation effect on the charging area, the heat dissipation method of this application may also include the following S401-S402.

[0099] S401, the controller determines the vehicle speed, the on / off status of the vehicle air conditioning, and the on / off status of the vehicle media player.

[0100] The vehicle air conditioning switch status includes the vehicle air conditioning being on and the vehicle air conditioning being off. The vehicle media player switch status includes the vehicle media player being on and the vehicle media player being off.

[0101] As one possible implementation, the controller can determine the vehicle speed signal from the Hall sensor connected to the controller and determine the vehicle speed based on the vehicle speed signal; obtain the AC signal from the air conditioning power supply interface and determine the on / off state of the vehicle air conditioning based on the AC signal; and obtain the vehicle player signal from the vehicle player power supply interface and determine the on / off state of the vehicle player based on the vehicle player signal.

[0102] The vehicle speed signal is used to indicate the vehicle speed. For example, the vehicle speed signal can be VIU_FL_VehicleSpeed. When the vehicle speed signal VIU_FL_VehicleSpeed ​​= 10, the controller determines the vehicle speed to be 10 km / h.

[0103] The AC signal is used to indicate the on / off status of the vehicle's air conditioning system. The AC signal includes a first AC signal and a second AC signal. The first AC signal indicates that the vehicle's air conditioning is on, and the second AC signal indicates that the vehicle's air conditioning is off.

[0104] When the controller determines that the AC signal is the first AC signal, it determines that the vehicle air conditioning switch state is the vehicle air conditioning on state; when the controller determines that the AC signal is the second AC signal, it determines that the vehicle air conditioning switch state is the vehicle air conditioning off state.

[0105] For example, the first AC signal can be AC_ACOnOff = 0x1. The first AC signal can be AC_ACOnOff = 0x0.

[0106] The vehicle player signal is used to indicate the on / off status of the vehicle player. The vehicle player signal includes a first vehicle player signal and a second vehicle player signal. The first vehicle player signal indicates that the vehicle player is on, and the second vehicle player signal indicates that the vehicle player is off.

[0107] When the controller determines that the vehicle player signal is the first vehicle player signal, it determines that the vehicle air conditioning switch status is the vehicle air conditioning on status; when the controller determines that the vehicle player signal is the second vehicle player signal, it determines that the vehicle air conditioning switch status is the vehicle air conditioning off status.

[0108] For example, the first in-vehicle player signal can be HU_MediaSoundSourceStatus=0x1, and the second in-vehicle player signal can be HU_MediaSoundSourceStatus=0x1.

[0109] S402. When the controller determines that the vehicle meets any of the multiple preset conditions, it controls the second fan to be turned on.

[0110] The preset conditions include a first preset condition, a second preset condition, and a third preset condition. The first preset condition is that the vehicle speed is greater than or equal to the vehicle speed threshold. The second preset condition is that the vehicle air conditioner is turned on. The third preset condition is that the vehicle media player is turned on.

[0111] The vehicle speed threshold can be set as needed. For example, it can be 5 km / h.

[0112] As one possible implementation, when the second fan switch is in the off state, the controller can switch the second fan switch from the off state to the closed state to control the second fan to be in the on state. When the second fan switch is in the closed state, the controller can control the second fan switch to remain in the closed state to control the second fan to be in the on state.

[0113] It should be noted that the first and second fans are in the on state, WLCM_Wireless_Mainfan = 0x1 and WLCM_Wireless_Supfan = 0x1.

[0114] Understandably, after controlling the first fan to be on, if the vehicle speed is greater than or equal to the vehicle speed threshold, or the vehicle air conditioning or vehicle media player is on, the controller can then control the second fan to be on. At this time, with both the first and second fans on simultaneously, the airflow in the charging area is accelerated, thereby improving heat dissipation. Furthermore, because the vehicle speed is greater than or equal to the vehicle speed threshold, or the vehicle air conditioning or vehicle media player is on, the noise from the vehicle, air conditioning, or player can partially mask the fan noise, thus reducing the noise impact of the cooling fans.

[0115] In one possible embodiment, in order to save power resources, the heat dissipation method of this application may further include the following S501.

[0116] S501. When the wireless charging device is in a power-off state, the controller controls the first fan and the second fan to be in a turned-off state.

[0117] As one possible implementation, when the switches of the first and second fans are in the closed state, the controller can control the switches of the first and second fans to switch from the closed state to the open state, thereby controlling the first and second fans to be in the off state. When the switches of the first and second fans are in the open state, the controller can control the switch of the second fan to remain in the open state, thereby controlling the first and second fans to be in the off state.

[0118] It should be noted that when the wireless charging device is in a power-off state, WLCM_WirelessHighCharging_Status = 0x0 and WLCM_WirelessCharging_Status = 0x0. The first fan and the second fan are in a turned-off state, WLCM_Wireless_Mainfan = 0x0 and WLCM_Wireless_Supfan = 0x0.

[0119] Understandably, when the wireless charging device is not powered, keeping the first and second fans off can save vehicle power and reduce the noise from the cooling fans.

[0120] In one possible embodiment, in order to determine that the wireless charging device is in a powered state, the heat dissipation method provided in this application embodiment may further include the following S601.

[0121] S601. When the controller detects that the wireless charging device is connected to the power-consuming equipment and the power-consuming equipment has wireless charging function, it determines that the wireless charging device is in a power supply state.

[0122] For details on determining whether the wireless charging device is in a powered state, please refer to S301 above, which will not be repeated here.

[0123] Understandably, once it is confirmed that the wireless charging device is in a powered state, controlling the activation status of the first and second fans based on the power supply of the wireless charging device can avoid the controller frequently detecting the power supply of the wireless charging device, thus reducing the controller's resource usage.
