[0027] 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.

[0028] The following describes the vehicle charging temperature adjustment method, device, vehicle and storage medium of the embodiment of the present application with reference to the accompanying drawings. In view of the technical problem that the related technologies mentioned in the above background technology cannot solve the situation that the mobile terminal heats up during wireless charging, and it is difficult to ensure that the mobile terminal can complete the charging action before disconnecting due to heating, thereby affecting the actual use of the mobile terminal and not being conducive to improving the user experience, the present application provides a vehicle charging temperature adjustment method, in which the temperature of the mobile terminal in the wireless charging state can be monitored, and combined with the ambient temperature in the vehicle, it is judged whether the mobile terminal has a risk of heating or low temperature charging, so that in the case of heating or low temperature charging risk, the vehicle's wireless charging temperature adjustment strategy is determined based on the current temperature, the ambient temperature in the vehicle and the parameters of the mobile terminal, and the opening of the wireless charging cover air outlet of the vehicle is adjusted based on the wireless charging temperature adjustment strategy or the temperature of the tray for placing the mobile terminal is adjusted, so that the mobile terminal is cooled down in the case of high temperature, and the mobile terminal is heated in the case of low temperature, until the current temperature of the mobile terminal is within the preset operating temperature range, thereby ensuring the charging safety of the mobile terminal while improving the charging status of the mobile terminal and improving the charging efficiency of the mobile terminal. Thereby, the technical problem in the related art that the mobile terminal cannot solve the problem of heating up during wireless charging, and it is difficult to ensure that the mobile terminal can complete the charging action before disconnecting due to heat, thereby affecting the actual use of the mobile terminal and being not conducive to improving the user experience is solved.

[0029] Before describing the vehicle charging temperature adjustment method according to the embodiment of the present application, the wireless charging technology involved in the embodiment of the present application is first described.

[0030] It is understandable that the wireless charging function of mobile terminals, such as mobile phones, has gradually been popularized in cars. Compared with the traditional charging method of wired connection, the biggest advantage of in-car wireless charging is:

[0031] Convenient and fast: In-vehicle wireless charging technology uses a contactless charging method, which does not require plugging in wires. Just place your mobile phone or other electronic devices in the charging area to charge quickly. This greatly improves the convenience of driving, especially for long journeys, so that drivers no longer need to worry about the battery level of their mobile phones during driving.

[0032] Safe and stable: In-vehicle wireless charging technology uses the principle of electromagnetic induction. When mobile phones and other electronic devices are placed in the charging area, energy is transmitted through the magnetic field. This charging method avoids the safety hazards existing in traditional charging methods, such as unstable voltage and aging lines.

[0033] Strong compatibility: In-car wireless charging technology has wide compatibility and can be applied to various brands and models of mobile phones, tablets and other electronic devices. This provides more convenience for drivers, and they no longer need to worry about charging different devices.

[0034] The OEMs have different choices for the configuration of the models launched according to the product positioning of different users. Influenced by the products of major mobile phone manufacturers, the charging power is mainly divided into 15w, 30w and 50w. The charging efficiency and safety of wireless charging technology have always been the focus of users.

[0035] Among them, the theoretical charging efficiency of wireless charging technology mainly depends on the loss of energy transmission. Since wireless charging involves electromagnetic wave transmission or other energy transmission methods, it will cause a certain amount of energy loss, and this part of energy is mainly converted into heat energy, which reduces the charging efficiency and causes the phone to heat up. This will cause the high temperature threshold strategy inside the phone. After the high temperature self-protection of the phone takes effect, the charging efficiency of the phone is further reduced, resulting in poor user experience, which causes complaints. According to current research and experimental results, the theoretical charging efficiency of wireless charging is usually between 80% and 90%.

[0036] The actual charging efficiency refers to the proportion of effective energy that wireless charging technology can transmit to the device under the conditions of simulating the actual use scenario in the actual use environment. The actual charging efficiency is affected by many factors, such as transmission distance, transmission medium, transmission distance, environmental interference, mobile phone model, etc. From the current experimental results, the actual charging efficiency of wireless charging technology is only between 60% and 70%.

[0037] In order to prevent users from complaining about overheating of mobile phones and low charging efficiency when experiencing wireless charging in cars, especially in the high temperature environment in summer, the embodiment of the present application can analyze and solve the problem from the following perspectives: An overview of the current research on interior decoration in the automotive industry shows that the shapes of most car models are distributed on the auxiliary instrument panel, which is usually near the front air outlet according to the user's usage habits. The benefits of this arrangement can also improve the heating of mobile phones during charging, but the effect is mostly not very obvious.

[0038] When using the wireless charging function in a high-temperature environment in summer or in special areas such as tropical areas: Because the mobile phone tray is generally arranged near the front air outlet and close to the air conditioning control module in the front cabin of the co-pilot, an air duct is added to connect to the air outlet of the mobile phone tray during the arrangement (generally, high-power wireless charging modules will have their own fans, but they have little effect in high-temperature environments). At the same time, a temperature sensor is set at the mobile phone tray to always sense the surface temperature of the mobile phone during wireless charging. You can even use an LCD instrument to display the current real-time temperature of the mobile phone to remind users to take the mobile phone away in time to avoid affecting the life of the mobile phone. Of course, when the temperature sensor obtains the temperature of the mobile phone, after the temperature sensor transmits a signal to the air conditioning control module, the air conditioning control module controls the opening of the air duct according to the blower to cool the mobile phone tray. After the temperature of the mobile phone at the mobile phone tray is reduced, the temperature sensor continues to send a signal to the air conditioning control module to adjust the opening of the duct to ensure that the wireless charging is in a suitable temperature environment, so as to ensure that the efficiency of charging is effectively improved.

[0039] Specifically, Figure 1 A schematic flow chart of a method for adjusting the charging temperature of a vehicle provided in an embodiment of the present application.

[0040] like Figure 1 As shown, the vehicle charging temperature adjustment method includes the following steps:

[0041] In step S101, the current temperature of the mobile terminal in the wireless charging state is obtained.

[0042] Based on the above architecture, when a user is wirelessly charging a mobile terminal, such as a mobile phone, the user can place the mobile terminal on the tray and obtain the current temperature of the mobile terminal through the temperature sensor of the tray.

[0043] In addition, in order to obtain a more accurate actual operating temperature of the mobile terminal, the embodiment of the present application can also receive the actual operating temperature obtained by the mobile terminal through self-test based on the wireless charging channel to achieve more accurate temperature judgment.

[0044] In step S102, it is determined whether the mobile terminal meets the preset operating conditions based on the current temperature and the ambient temperature in the vehicle.

[0045] It can be understood that, taking mobile phones as an example, through data sources such as big data, the embodiments of the present application can determine that the ideal working environment temperature of various models of mobile phones is between 15°C and 40°C, and the built-in software strategy temperature range is 15°C to 40°C.

[0046] Therefore, the embodiment of the present application can determine whether charging of the mobile terminal at the current temperature and the ambient temperature inside the vehicle will affect the charging efficiency and charging safety based on the current temperature and the ambient temperature inside the vehicle.

[0047] Among them, the preset operating conditions can be set accordingly by technical personnel in this field according to actual conditions and are not specifically limited here.

[0048] In step S103, if the preset operating conditions are not met, the vehicle's wireless charging temperature control strategy is determined based on the current temperature, the vehicle's ambient temperature, and the parameters of the mobile terminal, and the opening of the air outlet is adjusted or the temperature of the tray is adjusted based on the wireless charging temperature control strategy until the current temperature of the mobile terminal is within the preset operating temperature range.

[0049] As a possible implementation method, when the preset operating conditions are not met, that is, when the charging efficiency is low or there are safety hazards, the embodiment of the present application can determine the vehicle's wireless charging temperature control strategy based on the current temperature, the ambient temperature in the vehicle, and the parameters of the mobile terminal.

[0050] Among them, the parameters of the mobile terminal include the model of the mobile terminal, the battery aging degree of the mobile terminal, etc. The embodiment of the present application can determine the appropriate charging temperature according to the model of the mobile terminal, and determine the actual charging strategy according to the battery aging degree, such as determining the maximum battery capacity percentage according to the battery aging degree.

[0051] For example, when determining the wireless charging temperature adjustment strategy, the embodiment of the present application may include the following steps:

[0052] Step S1: Temperature monitoring.

[0053] Real-time monitoring: Continuously monitor the temperature of the wireless charging pad and the phone battery.

[0054] Temperature threshold: Set a safe temperature range, such as 35℃ to 45℃.

[0055] Step S2: Adjust charging power.

[0056] Low temperature: If the ambient temperature is low, you can increase the charging power appropriately, but make sure it does not exceed the maximum charging power recommended by the phone manufacturer.

[0057] High temperature: When it is detected that the temperature of the charging plate or the mobile phone battery is too high, the charging power is automatically reduced, or charging is suspended until the temperature drops to a safe range, or the opening of the wireless charging cover air outlet of the vehicle is adjusted to cool the mobile phone; when it is detected that the temperature of the charging plate or the mobile phone battery is too low, the temperature of the tray used to place the mobile terminal is adjusted to heat the mobile phone.

[0058] Step S3: Dynamic adjustment.

[0059] The embodiments of the present application can utilize intelligent algorithms to dynamically adjust the charging strategy according to the mobile phone model and battery aging degree, and can also allow the user to set different temperature thresholds and charging modes according to personal preferences.

[0060] Optionally, in one embodiment of the present application, a wireless charging temperature control strategy for a vehicle is determined based on the current temperature, the ambient temperature in the vehicle, and the parameters of the mobile terminal, including: determining a theoretical temperature range of the mobile terminal based on the parameters, wherein the theoretical temperature range includes a first preset temperature range, a second preset temperature range, a third preset temperature range, a fourth preset temperature range, and a fifth preset temperature range; when the current temperature is within the first preset temperature range, determining the wireless charging temperature control strategy to adjust the opening to a first preset percentage; when the current temperature is within the second preset temperature range, determining the wireless charging temperature control strategy to adjust the opening to a second preset percentage, wherein the lower limit value of the second preset temperature range is greater than the upper limit value of the first preset temperature range, and the second preset percentage is greater than the first preset percentage; when the current temperature is within the first preset temperature range, determining the wireless charging temperature control strategy to adjust the opening to a second preset percentage When the temperature is within the third preset temperature range, the wireless charging temperature control strategy is determined to adjust the opening to the third preset percentage, wherein the lower limit value of the third preset temperature range is greater than the upper limit value of the second preset temperature range, and the third preset percentage is greater than the second preset percentage; when the current temperature is within the fourth preset temperature range, the wireless charging temperature control strategy is determined to adjust the opening to the fourth preset percentage, wherein the lower limit value of the fourth preset temperature range is greater than the upper limit value of the third preset temperature range, and the fourth preset percentage is greater than the third preset percentage; when the current temperature is within the fifth preset temperature range, the wireless charging temperature control strategy is determined to adjust the opening to the fifth preset percentage, wherein the lower limit value of the fifth preset temperature range is greater than the upper limit value of the fourth preset temperature range, and the fifth preset percentage is greater than the fourth preset percentage.

[0061] For example, when the temperature sensor detects that the temperature of the mobile terminal exceeds a certain temperature threshold, the sensor transmits a signal to the vehicle's air conditioning control module, which adjusts the air door opening through the blower and continues to adjust the temperature range to 15°C to 20°C. The setting strategy is that the opening of the wireless charging cover air outlet is 25%;

[0062] 20℃ to 25℃ setting strategy The opening of the wireless charging cover air outlet is 40%;

[0063] 25℃ to 30℃ setting strategy The opening of the wireless charging cover air outlet is 55%;

[0064] 30℃ to 35℃ setting strategy The opening of the wireless charging cover air outlet is 75%;

[0065] At 35℃ and above, the opening of the wireless charging cover air outlet is 100%.

[0066] As the temperature gets higher and higher, the air damper opening will gradually increase, that is, the cooling effect will get better and better. After running for a period of time, the temperature sensor senses that the temperature has dropped, transmits a signal for negative feedback, and the air damper opening decreases, reducing the air volume loss, so that the mobile terminal charging is always in a suitable environment.

[0067] In the same winter or low-temperature areas, the built-in software strategy temperature range is 10°C and below. In a low-temperature environment, the engine waste heat is used to preheat the mobile phone tray with 100% throttle opening. When the mobile terminal is at a suitable temperature, the charging efficiency will be improved.

[0068] Optionally, in one embodiment of the present application, determining the wireless charging temperature control strategy of the vehicle based on the current temperature, the in-vehicle ambient temperature and the parameters of the mobile terminal also includes: correcting the theoretical temperature range based on the in-vehicle ambient temperature.

[0069] In some embodiments, the embodiments of the present application can correct the theoretical temperature range according to the ambient temperature inside the vehicle.

[0070] For example, when a user enters a car with air conditioning on from a high temperature environment, the mobile terminal is synchronized with the external environment and is in a high temperature state. When charging, the temperature of the mobile terminal will gradually change with the ambient temperature inside the car. At this time, the embodiment of the present application can correct the theoretical temperature range, thereby adjusting the opening, reducing energy consumption, and avoiding excessive air flow from the air outlet affecting users and passengers.

[0071] Optionally, in an embodiment of the present application, it also includes: obtaining a battery change rate of the mobile terminal within a preset time period; and correcting the theoretical temperature range based on the battery change rate.

[0072] In other embodiments, the embodiments of the present application may also correct the theoretical temperature range according to the rate of change of the power of the mobile terminal within a preset time period.

[0073] For example, when an application is running in the background of a mobile terminal, such as music or navigation, it will affect the charging efficiency and the temperature of the mobile terminal. At this time, the theoretical temperature range can be corrected to adjust the opening to prevent the mobile terminal from overheating in advance.

[0074] In addition, the embodiment of the present application can also determine the impact of the current temperature on the charging efficiency of the mobile terminal based on the rate of change of the power, thereby correcting the theoretical temperature range, that is, achieving real-time adjustment through negative feedback.

[0075] Optionally, in one embodiment of the present application, after adjusting the opening of the air outlet or adjusting the temperature of the tray based on the wireless charging temperature control strategy, it also includes: accumulating the time when the mobile terminal does not meet the preset operating conditions; determining whether the time exceeds the preset time; if it exceeds the preset time, obtaining the current running program list of the mobile terminal; filtering out at least one program that meets the preset background conditions from the current running program list, and ending the current process of at least one program.

[0076] During the actual execution process, there may be too many programs running in the background, resulting in little effect of external cooling. In this case, the embodiment of the present application can determine the cumulative time that the mobile terminal is under high temperature after executing the wireless charging temperature adjustment strategy, so that when the cumulative time exceeds a certain value, part of the currently running programs will be terminated to reduce the probability of heating of the mobile terminal.

[0077] For example, the preset background condition is that the program currently used by the mobile terminal will not be affected after the program is terminated.

[0078] Among them, the preset duration and preset background conditions can be set accordingly by technical personnel in this field according to actual conditions, and no specific restrictions are made here.

[0079] Combination Figure 2 and Figure 3 As shown, the working principle of the vehicle charging temperature adjustment method of the embodiment of the present application is described in detail with an embodiment.

[0080] like Figure 2 As shown, the embodiments of the present application may involve temperature sensors, air conditioning control modules, blowers, dampers and other equipment.

[0081] In the actual implementation process, when the temperature sensor detects that the temperature of the mobile terminal exceeds a certain temperature threshold, the sensor transmits a signal to the vehicle's air conditioning control module, and the air conditioning control module adjusts the air door opening through the blower, and continues to adjust the temperature range to 15°C to 20°C. The setting strategy wireless charging cover air outlet opening is 25%;

[0082] 20℃ to 25℃ setting strategy The opening of the wireless charging cover air outlet is 40%;

[0083] 25℃ to 30℃ setting strategy The opening of the wireless charging cover air outlet is 55%;

[0084] 30℃ to 35℃ setting strategy The opening of the wireless charging cover air outlet is 75%;

[0085] At 35℃ and above, the opening of the wireless charging cover air outlet is 100%.

[0086] As the temperature gets higher and higher, the air damper opening will gradually increase, that is, the cooling effect will get better and better. After running for a period of time, the temperature sensor senses that the temperature has dropped, transmits a signal for negative feedback, and the air damper opening decreases, reducing the air volume loss, so that the mobile terminal charging is always in a suitable environment.

[0087] In the same winter or low-temperature areas, the built-in software strategy temperature range is 10°C and below. In a low-temperature environment, the engine waste heat is used to preheat the mobile phone tray with 100% throttle opening. When the mobile terminal is at a suitable temperature, the charging efficiency will be improved.

[0088] Based on the above adjustments, Figure 3 As shown, the charging efficiency of the embodiment of the present application is significantly improved.

[0089] The result is the effect when the cold air duct is fully opened in a high temperature environment, i.e. 35°C and above. It can be seen that the improvement effect is 8% higher than that without adding the air duct after half an hour of charging time. The improvement effect is relatively obvious. Considering the certainty of the evaporator power of the whole vehicle air conditioner, the introduction of adjusting the air door opening according to the temperature has a certain economy, reduces energy loss, and avoids the increase of the cold air duct of the mobile phone tray.

[0090] This reduces the cooling effect of the vehicle's air conditioning and improves balance.
