[0051] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0052] The heat dissipation method, device, vehicle and storage medium of the vehicle-mounted wireless charging system of the embodiment of the present application are described below with reference to the accompanying drawings. In view of the problems of slow charging speed and poor heat dissipation performance during wireless charging mentioned in the above background technology, the present application provides a heat dissipation method for a vehicle-mounted wireless charging system, in which at least one wireless charging scenario of the target device is identified, and the wireless charging strategy of the vehicle-mounted wireless charging system for the target device is determined according to each wireless charging scenario, and the heat dissipation strategy of the heat dissipation system is matched, and the real-time temperature data of the vehicle-mounted wireless charging system is monitored. If the real-time temperature data is greater than the preset charging temperature threshold, the real-time temperature data is adjusted by the heat dissipation system based on the heat dissipation strategy to generate a real-time temperature data adjustment result, or the output power of the wireless charging system is adjusted by the power control unit to generate a power adjustment result, so as to control the heat dissipation of the vehicle-mounted wireless charging system according to the adjusted real-time temperature data and output power. In this way, the problems of slow charging speed and poor heat dissipation performance during wireless charging are solved. By using a built-in intelligent heat dissipation fan, when the vehicle battery system is wirelessly charged, the wind speed and charging power of the intelligent heat dissipation fan are adjusted according to the real-time temperature data based on the intelligent optimization model to control the heat dissipation of the vehicle-mounted wireless charging system.

[0053] Specifically, Figure 1 A schematic flow chart of a heat dissipation method for a vehicle-mounted wireless charging system provided in an embodiment of the present application.

[0054] like Figure 1 As shown, the vehicle-mounted wireless charging system is provided with a heat dissipation control component and a power control unit, and the heat dissipation method of the vehicle-mounted wireless charging system includes the following steps:

[0055] In step S101, at least one wireless charging scenario of a target device is identified, and a wireless charging strategy of the vehicle-mounted wireless charging system for the target device is determined according to each wireless charging scenario.

[0056] Specifically, in daily life, based on the different needs of users, there are many wireless charging scenarios, such as charging of electronic devices, charging of electric vehicles, etc. Different wireless charging scenarios have corresponding charging strategies, that is, the output charging power and charging transmitter voltage are different. Therefore, the embodiment of the present application needs to determine the wireless charging strategy of the vehicle-mounted wireless charging system for the target device based on the identified wireless charging scenario, so as to realize the charging function of the target device.

[0057] Among them, Figure 2 As shown, the vehicle-mounted wireless charging system adopted in the embodiment of the present application mainly includes a wireless charging transmitting module, a wireless charging receiving module and a target device, wherein the wireless charging transmitting module and the wireless charging receiving module are charging component modules, which generate an alternating magnetic field through the conversion of direct current and alternating current for energy transmission, and then convert it into electrical energy through energy capture by the receiving module for use by the target device. At the same time, during the wireless charging process, the power control unit is also required to be responsible for adjusting the working parameters of the wireless charging transmitting module to ensure the stability of the charging power. The power control unit can flexibly achieve safety through changes in power.

[0058] Specifically, in the embodiment of the present application, first, the direct current (DC) of the wireless charging system is converted into alternating current (AC) suitable for the wireless charging transmitting module through a voltage converter, and the wireless charging transmitting module generates an alternating magnetic field through electromagnetic induction technology to transmit energy to the wireless charging receiving module; secondly, the wireless charging receiving module (usually built into the target device to be charged) receives the magnetic field energy generated by the wireless charging transmitting module, generates an alternating current in the alternating electromagnetic field, and then converts it into a direct current to charge the corresponding target device. At the same time, during the transmission process, the power control unit (i.e., MCU (Microcontroller Unit)) adjusts the power output of the wireless charging transmitting module according to the charging requirements and battery status of the target device through intelligent algorithms such as AGC (Automatic Gain Control) or PLL (Phase-Locked Loop) to ensure that the charging process is both efficient and safe.

[0059] Furthermore, during the charging process, communication modules such as CAN (Controller Area Network), SPI (Serial Peripheral Interface), I2C (Inter-Integrated Circuit) and other communication means are also needed to achieve millisecond-level command issuance and information synchronization between the on-board wireless charging system and the vehicle and other devices.

[0060] In step S102, the heat dissipation strategy of the heat dissipation system is matched based on the wireless charging strategy of the target device.

[0061] According to one embodiment of the present application, a heat dissipation strategy of a heat dissipation system is matched based on a wireless charging strategy of a target device, including: obtaining the output power of the vehicle-mounted wireless charging system in each wireless charging scenario; determining the real-time temperature data of the vehicle-mounted wireless charging system corresponding to each wireless charging scenario according to the output power, and generating a corresponding heat dissipation strategy according to the temperature data; constructing a mapping relationship between the wireless charging strategy and the heat dissipation strategy according to the output power and the heat dissipation strategy, so as to determine the heat dissipation strategy corresponding to the wireless charging strategy based on the mapping relationship.

[0062] Specifically, when the vehicle-mounted wireless charging system is charging the target device, the charging speed and battery life are often affected due to poor heat dissipation performance. Therefore, when the vehicle-mounted wireless charging system is charging the target device, the heat dissipation function during the charging process also needs to be considered.

[0063] Since the air-cooled heat dissipation used in the relevant technology can no longer meet the needs of high-power (for example, 60W or even 65W) wireless charging, and for charging environments under different working conditions, the continuous operation of the air-cooled heat dissipation has a certain degree of impact on the health loss of the equipment. Therefore, the embodiment of the present application uses a built-in cooling fan for the vehicle-mounted wireless charging system to cool the target device when charging, and at different temperatures, for example, on winter nights or in areas with relatively low temperatures, the heat generated during charging is transmitted to the external space by the thermal pad, etc., and the use of the cooling fan is appropriately adjusted (for example, reducing the wind speed) according to the intelligent algorithm to achieve continuous and effective use of the target device.

[0064] Specifically, the embodiment of the present application adopts a heat dissipation system to dissipate heat from the vehicle-mounted wireless charging system, wherein the heat dissipation system mainly includes a temperature sensor, a fan or a heat dissipation fan, a heat sink, a thermal pad, and an intelligent optimization model.

[0065] Among them, Figure 3As shown, the heat sink is used for heat conduction during daily charging to ensure that the normal heat generated by the on-board wireless charging system during charging is conducted from the device to the aluminum alloy shell, thereby dissipating heat through the shell and reducing the temperature rise of the on-board wireless charging system; the thermal pad can effectively fill the gap, improve the heat conduction efficiency, and also have the functions of insulation and shock absorption; the temperature sensor is used to monitor the real-time changes of the temperature data of the on-board wireless charging system, and output prompt instructions when the temperature is too high or other temperature risks are detected, and at the same time, the temperature data is converted into a usable output signal. The temperature sensor mainly includes a contact temperature sensor (such as a thermal resistor or a thermocouple) and a non-contact temperature sensor (such as a radiation thermometer). In the embodiment of the present application, a contact temperature sensor is preferably used, which has a high cost performance and is suitable for direct addition to the on-board wireless charging system; the intelligent optimization model can intelligently adjust the wind speed of the cooling fan after the temperature sensor issues an instruction, make a judgment simultaneously, warn the on-board wireless charging system, and instruct the power control unit to adjust the charging power.

[0066] Therefore, the embodiment of the present application obtains the output power of the vehicle-mounted wireless charging system in each wireless charging scenario based on different wireless charging scenarios, so as to determine the real-time temperature data of the vehicle-mounted wireless charging system corresponding to each wireless charging scenario according to the output power, and generate the corresponding heat dissipation strategy according to the temperature data, and construct a mapping relationship between the wireless charging strategy and the heat dissipation strategy according to the output power and the heat dissipation strategy, and determine the heat dissipation strategy corresponding to the wireless charging strategy based on the mapping relationship.

[0067] In step S103, the real-time temperature data of the vehicle-mounted wireless charging system is monitored. If the real-time temperature data is greater than the preset charging temperature threshold, the real-time temperature data is adjusted using the heat dissipation system based on the heat dissipation strategy to generate a real-time temperature data adjustment result, or the output power of the wireless charging system is adjusted using the power control unit to generate a power adjustment result, so as to control the heat dissipation of the vehicle-mounted wireless charging system according to the adjusted real-time temperature data and output power.

[0068] According to one embodiment of the present application, before the real-time temperature data is adjusted using the heat dissipation system based on the heat dissipation strategy, it also includes: based on the real-time temperature data of the vehicle-mounted wireless charging system, the heat dissipation system is optimized and adjusted using a preset optimization model, so as to adjust the real-time temperature data according to the optimized and adjusted heat dissipation system.

[0069] According to one embodiment of the present application, real-time temperature data is adjusted using a heat dissipation system based on a heat dissipation strategy, including: receiving a temperature adjustment instruction; adjusting the operating speed of a heat dissipation fan and the thermal conduction efficiency of a heat sink in the heat dissipation system according to the temperature adjustment instruction; and adjusting the real-time temperature data according to the operating speed of the heat dissipation fan and the thermal conduction efficiency of the heat sink.

[0070] Among them, the preset charging temperature threshold can be set by technical personnel in this field according to actual charging heat dissipation requirements, and can also be obtained through a limited number of computer simulations, and is not specifically limited here.

[0071] Specifically, when the vehicle-mounted wireless charging system of the embodiment of the present application charges the target device, it is necessary to monitor the real-time temperature data of the vehicle-mounted wireless charging system through a temperature sensor in real time, and determine whether the real-time temperature data is greater than a preset charging temperature threshold. If the real-time temperature data is greater than the preset charging temperature threshold, that is, the temperature of the vehicle-mounted wireless charging system is too high, the temperature sensor will issue a temperature adjustment instruction. After receiving the temperature adjustment instruction, the intelligent optimization model in the heat dissipation system will intelligently adjust the operating speed of the cooling fan and the thermal conduction efficiency of the heat sink according to the real-time temperature data, so as to cool the vehicle-mounted wireless charging system according to the operating speed of the cooling fan and the thermal conduction efficiency of the heat sink.

[0072] It should be noted that in order to optimize the parameter adjustment, the embodiments of the present application can automatically adjust the parameter values ​​of the heat dissipation system according to the real-time monitored temperature data through a preset optimization model, such as a gradient algorithm, a genetic algorithm, a projection algorithm and other machine learning technologies. The parameter values ​​of the heat dissipation system can be adjusted at any time to achieve real-time optimization of the heat dissipation system. At the same time, regularization or data cleaning can be used to effectively distinguish the temperature sensor transmission data for intelligent adjustment of the wind speed or the power output value of the vehicle-mounted wireless charging system. At the same time, the projection algorithm can also solve optimization problems with constraints, and try to use a combined projection algorithm to improve the heat dissipation efficiency. There is still a lot of room for improvement in the projection algorithm, which is guaranteed for subsequent intelligent improvement or cost reduction and efficiency improvement.

[0073] Optionally, when the embodiment of the present application monitors that the real-time temperature data is greater than a preset charging temperature threshold, it can also notify the power control unit in the vehicle-mounted wireless charging system through an intelligent optimization model to adjust the output power of the vehicle-mounted wireless charging system to reduce the charging power to prevent the device from overheating.

[0074] Therefore, in the process of charging the target device by the vehicle-mounted wireless charging system, the function of effective heat dissipation is realized, and the charging process of the target device is realized through energy conversion between the wireless charging transmitting module and the wireless charging receiving module based on the heat dissipation performance. The specific wireless charging process has been discussed above and will not be described in detail here.

[0075] According to one embodiment of the present application, the heat dissipation method of the above-mentioned vehicle-mounted wireless charging system also includes: judging whether the real-time temperature data of the vehicle-mounted wireless charging system is in an abnormal state; if the real-time temperature data is in an abnormal state, controlling the heat dissipation system to generate an emergency response mechanism to control the heat dissipation of the vehicle-mounted wireless charging system.

[0076] In the embodiment of the present application, it is also necessary to monitor abnormal conditions that occur during the wireless charging process. For example, if the vehicle-mounted wireless charging system reaches an abnormally high temperature, it will be detrimental to the overall charging efficiency. Therefore, it is necessary to control the cooling system to generate an emergency response mechanism to activate or enhance the operation of the cooling system, such as increasing the speed of the cooling fan, turning on additional cooling equipment, increasing the flow rate of the coolant, etc., so as to improve the cooling efficiency and control the heat dissipation of the vehicle-mounted wireless charging system.

[0077] According to the heat dissipation method of the vehicle-mounted wireless charging system of the embodiment of the present application, at least one wireless charging scenario of the target device is identified, and the wireless charging strategy of the vehicle-mounted wireless charging system for the target device is determined according to each wireless charging scenario, and the heat dissipation strategy of the heat dissipation system is matched, and the real-time temperature data of the vehicle-mounted wireless charging system is monitored. If the real-time temperature data is greater than the preset charging temperature threshold, the real-time temperature data is adjusted by the heat dissipation system based on the heat dissipation strategy to generate a real-time temperature data adjustment result, or the output power of the wireless charging system is adjusted by the power control unit to generate a power adjustment result, so as to control the heat dissipation of the vehicle-mounted wireless charging system according to the adjusted real-time temperature data and output power. In this way, the problems of slow charging speed and poor heat dissipation performance during wireless charging are solved. Through the built-in intelligent heat dissipation fan, when the vehicle battery system is wirelessly charged, the wind speed and charging power of the intelligent heat dissipation fan are adjusted according to the real-time temperature data based on the intelligent optimization model to control the heat dissipation of the vehicle-mounted wireless charging system.

[0078] Next, the heat dissipation device of the vehicle-mounted wireless charging system proposed in the embodiment of the present application is described with reference to the accompanying drawings.

If the real-time temperature data is greater than a preset charging temperature threshold, the real-time temperature data is adjusted using the heat dissipation system based on the heat dissipation strategy to generate a real-time temperature data adjustment result, or the output power of the wireless charging system is adjusted using the power control unit to generate a power adjustment result, so as to control the heat dissipation of the vehicle-mounted wireless charging system according to the adjusted real-time temperature data and output power.

[0084] According to an embodiment of the present application, the matching module 200 is specifically used for:

[0085] Obtain the output power of the vehicle wireless charging system in each wireless charging scenario;

[0086] Determine the real-time temperature data of the on-board wireless charging system corresponding to each wireless charging scenario based on the output power, and generate the corresponding heat dissipation strategy based on the temperature data;

[0087] A mapping relationship between the wireless charging strategy and the heat dissipation strategy is constructed according to the output power and the heat dissipation strategy, so as to determine the heat dissipation strategy corresponding to the wireless charging strategy based on the mapping relationship.

[0088] According to an embodiment of the present application, before adjusting the real-time temperature data using the heat dissipation system based on the heat dissipation strategy, the control module 300 is further configured to:

[0089] Based on the real-time temperature data of the on-board wireless charging system, the heat dissipation system is optimized and adjusted using a preset optimization model, so that the real-time temperature data is adjusted according to the optimized and adjusted heat dissipation system.

[0090] According to one embodiment of the present application, the control module 300 is specifically configured to:

[0091] receiving temperature adjustment instructions;

[0092] Adjust the running speed of the cooling fan and the heat conduction efficiency of the heat sink in the cooling system according to the temperature adjustment instruction;

[0093] The real-time temperature data is adjusted according to the operating speed of the cooling fan and the heat conduction efficiency of the heat sink.

[0094] According to one embodiment of the present application, the heat dissipation device 10 of the vehicle-mounted wireless charging system is further used for:

[0095] Determine whether the real-time temperature data of the vehicle wireless charging system is in an abnormal state;

[0096] If the real-time temperature data is in an abnormal state, the cooling system is controlled to generate an emergency response mechanism to control the cooling of the on-board wireless charging system.

[0097] According to the heat dissipation device of the vehicle-mounted wireless charging system of the embodiment of the present application, at least one wireless charging scenario of the target device is identified, and the wireless charging strategy of the vehicle-mounted wireless charging system for the target device is determined according to each wireless charging scenario, and the heat dissipation strategy of the heat dissipation system is matched, and the real-time temperature data of the vehicle-mounted wireless charging system is monitored. If the real-time temperature data is greater than the preset charging temperature threshold, the real-time temperature data is adjusted by the heat dissipation system based on the heat dissipation strategy to generate a real-time temperature data adjustment result, or the output power of the wireless charging system is adjusted by the power control unit to generate a power adjustment result, so as to control the heat dissipation of the vehicle-mounted wireless charging system according to the adjusted real-time temperature data and output power.
