[0026] Based on the description of the above background technology, the following situations also exist in the related technology:

[0027] The vehicle becomes a mobile space, providing a lot of convenience for users. To facilitate users to charge mobile terminals such as mobile phones conveniently in the vehicle, in-vehicle wireless charging devices are installed on the vehicle. The core of wireless charging technology is the wireless charging chip, which is the key to realizing wireless power transmission. Specifically, wireless charging chips involve two types: receiving chips and transmitting chips.

[0028] Transmitting chip: Built into the wireless charger, such as a charging pad or a charging stand. Its main function is to generate an electromagnetic field, and through this electromagnetic field, transmit electrical energy to the receiving chip.

[0029] Receiving chip: Built into the device to be charged, such as a smartphone or a tablet. Its task is to receive electrical energy from the transmitting device through electromagnetic induction and convert it into electrical energy that the battery can accept.

[0030] The collaborative work of the receiving chip and the transmitting chip enables electrical energy to be transmitted from the charger to the device without physical connection, thus realizing the convenience of wireless charging. In addition, the wireless charging chip can also help improve the battery charging efficiency and protect the battery life. Although the charging speed of wireless charging is slightly slower than that of wired charging, its safety and convenience are incomparable to traditional wired charging methods. At the same time, through electromagnetic induction technology, the wireless charging chip can better protect the battery and avoid battery damage problems such as overcharging or over-discharging.

[0031] However, wireless charging transmits electrical energy from the transmitter to the receiver through the principle of electromagnetic induction, and this process will generate heat. During normal wireless charging, it is normal for the battery to generate a certain amount of heat. However, if we frequently pick up mobile terminals such as mobile phones, it may cause continuous changes and fluctuations in the battery temperature. This frequent temperature change may cause certain stress on the battery, and in the long run, it may affect the battery life and performance.

[0032] However, it should also be clear that this kind of damage will not appear immediately, but gradually accumulates during long-term use.

[0033] To sum up, frequent picking up during wireless charging may cause certain damage to the battery, but this kind of damage accumulates gradually during long-term use. To reduce this kind of damage, users should try to avoid frequently picking up mobile terminals during charging, but it is very difficult to change the usage habits of users when using in-vehicle wireless charging devices for wireless charging inside the vehicle. Therefore, in order to extend the battery life and ensure the healthy state of the battery, it is necessary to change the control strategy of wireless charging without changing the user's usage habits.

[0034] The control method, device, electronic device and vehicle for in-vehicle wireless charging provided by this application perform different intelligent optimization controls on the charging process according to the operating state of the in-vehicle wireless charging device when the user conducts wireless charging. When the operating state is the on state, charging control is performed based on the initial battery level and the number of charging interruptions, ensuring different charging control strategies are adopted for different battery levels and different numbers of charging interruptions to protect the battery health during the charging process. When the operating state is the off state and the mobile terminal is a legitimate Bluetooth key, charging control is performed based on the initial battery level and the navigation destination, ensuring that the mobile terminal has a healthy battery level when the user arrives at the navigation destination while retaining the user's original control habits, and at the same time reducing the impact on battery health during the charging process. By associating the wireless charging control process with the battery level and navigation of the mobile terminal, and considering factors such as whether the mobile terminal is a digital key device, intelligent charging control is performed to avoid damage to the battery of the mobile terminal during the wireless charging process, and at the same time to avoid the problem of insufficient mobile phone battery level when the user arrives at the destination due to ignoring the actual state of the in-vehicle wireless charging device, improving the user experience of using in-vehicle wireless charging.

[0035] The following will specifically describe the control method for in-vehicle wireless charging provided by the embodiments of this application with reference to the accompanying drawings.

[0036] In some embodiments, as Figure 1 shown, a control method for in-vehicle wireless charging includes:

[0037] Step 101: In response to detecting that the mobile terminal is located at the wireless charging position after the vehicle is ignited, determine the initial battery level of the mobile terminal and the operating state of the in-vehicle wireless charging device.

[0038] In specific implementation, since the power supply source of the in-vehicle wireless charging device is the vehicle, specifically the vehicle's on-board battery, and whether to supply power to the in-vehicle wireless charging device requires user control. Exemplarily, a display control for controlling the in-vehicle wireless charging device can be displayed on the central control display screen, or a physical switch button can be separately set to control the in-vehicle wireless charging device.

[0039] Taking the display control to control the in-vehicle wireless charging device as an example, after the vehicle is ignited and started, the central control display screen is automatically started, and the display control is displayed. If the display control shows the on state (for example, the text "on" is displayed in the display control, or a graphic indicating on, which is not limited here), it means that power has been supplied to the in-vehicle wireless charging device. At this time, clicking the display control will stop supplying power to the in-vehicle wireless charging device (or turn off the wireless charging function of the in-vehicle wireless charging device), and the operating state of the in-vehicle wireless charging device will be switched, switching from the on state to the off state. The in-vehicle wireless device in the off state will not be able to wirelessly charge the mobile terminal.

[0040] If the user clicks on the display control in the off state, power will be supplied to the in-vehicle wireless charging device (or the wireless charging function of the in-vehicle wireless charging device will be enabled), and the operating state of the in-vehicle wireless charging device will be switched, from the off state to the on state. The in-vehicle wireless device in the on state will wirelessly charge the mobile terminal located at the wireless charging position.

[0041] Among them, if the user selects the memory mode, after the vehicle is ignited, the in-vehicle wireless charging device will be set to the state after the last vehicle shutdown. If the user does not make any settings, after the vehicle is ignited, the in-vehicle wireless charging device will be set to the default state. For the convenience of the user, the default state is generally the on state.

[0042] Therefore, after the vehicle is ignited, if it is detected that the mobile terminal is located at the wireless charging position, it indicates that the user has a wireless charging requirement. At this time, it is necessary to determine the initial battery level of the mobile terminal and the operating state of the in-vehicle wireless charging device. Since the purpose of the user to charge is to ensure sufficient battery power, the initial battery level determines the size of the charging requirement. The lower the initial battery level, the greater the charging requirement. And the operating state of the in-vehicle wireless charging device determines whether the in-vehicle wireless charging device has the wireless charging ability at this time, and determines whether it is necessary to automatically switch the operating state during charging control.

[0043] Step 102: In response to the operating state being the on state, perform charging control on the mobile terminal according to the initial battery level and / or the number of charging interruptions when the mobile terminal is removed from the wireless charging position.

[0044] In specific implementation, if the operating state is the on state, it means that the in-vehicle wireless charging device has the wireless charging function. At this time, it is necessary to control the charging process according to the user's usage habits and the initial battery level to protect the health of the battery and avoid affecting the service life of the battery.

[0045] Exemplarily, if the initial battery level is less than 50%, the battery level of the mobile terminal is relatively low at this time, and there is a relatively large charging demand. At this time, the main focus is on charging the mobile terminal to ensure that the user can use the mobile terminal for a long time. At this time, the impact of frequent picking up and placing on battery health can be ignored. Therefore, regardless of the number of charging interruptions, the in-vehicle wireless charging device will remain in the on state to ensure that the user's mobile terminal has sufficient power for subsequent continuous use. At this time, within the T1 time after the user first places the mobile terminal (the first time after this ignition) on the wireless charging position, regardless of the number of charging interruptions, the mobile terminal will be charged when it is located on the wireless charging position. If within the T1 time, the battery level is greater than or equal to 80%, it means that the battery level is already sufficient to support the long-term use of the mobile terminal. The charging of the mobile terminal is stopped by switching the operating state, and when the battery level is less than 50% again, the charging of the mobile terminal is resumed by switching the operating state, and the timing of T1 is repeated. Because after the battery level reaches 80%, it is sufficient for the user to continue using, and it can avoid the impact of frequent picking up and placing during subsequent charging on the battery, reducing the accumulation speed of damage caused by frequent picking up and placing to ensure the health of the battery.

[0046] After the T1 time ends, if the battery level of the mobile terminal is less than 80%, the T2 timing is started. Within the T2 time, if the user picks up and places the mobile phone three times, that is, the number of charging interruptions is greater than or equal to 3 times, it is considered that the user has a need to frequently use the mobile phone. At this time, the charging is stopped until it is detected that the battery level < 50%, and then the charging is continued and the T1 timing is restarted. If after the T1 ends, the user does not pick up and place the mobile phone, the charging continues until the battery level of the mobile phone reaches 80%.

[0047] If the initial battery level of the mobile terminal is in the range of [50%, 80%), it means that the charging demand is relatively low at this time, and the main focus is on protecting battery health. If the number of charging interruptions is less than 3 times, it is normal use and will not damage the battery. If the number of charging interruptions is greater than or equal to 3 times, it means that the user frequently picks up and places the mobile phone at this time. At this time, to reduce the accumulation of damage, the charging of the mobile terminal will be stopped.

[0048] If the initial battery level is greater than or equal to 80%, at this time the user's mobile phone has sufficient power, and if the battery is frequently charged and interrupted at this time, it will affect the health of the mobile phone battery. At this time, if the user places the mobile phone on the wireless charging position, the charging will be controlled according to the navigation destination.

[0049] When the navigation destination is a first - type destination such as a company / home / mall with convenient charging facilities, the user can charge at any time in the first - type destination, so the mobile terminal is no longer charged, avoiding the accumulation of damage to the battery caused by frequent charging and discharging. When the navigation destination is a second - type destination such as a suburb / mountain area where the charging facilities are not perfect, in order to ensure that the user can use the mobile terminal without worry for a long time, the mobile terminal continues to be charged until it is fully charged.

[0050] Step 103: In response to the operating state being the off state and the mobile terminal being a legal Bluetooth key, perform charging control on the mobile terminal according to the initial battery level and / or the navigation destination of the vehicle.

[0051] In specific implementation, if the operating state is the off state, it means that the in - vehicle wireless charging device does not have the charging ability and cannot charge the mobile terminal at this time. This may be a self - protection measure for the user's mobile terminal battery, or there may be a situation where the user forgets to turn it on. Then when the mobile phone is placed in the wireless charging position, the Bluetooth antenna judges whether this mobile phone is an authorized legal key mobile phone according to the signal strength. If so, the in - vehicle wireless charging device reads the initial battery level information of the mobile phone. If the initial battery level ≥ 50%, it means that the charging demand is low, and at this time, the in - vehicle wireless charging device remains in the off state and there is no need to charge the mobile terminal.

[0052] If the initial battery level < 50% and the navigation destination is a first - type destination with convenient charging facilities, the in - vehicle wireless charging device remains in the off state and there is no need to charge the mobile terminal; if the navigation destination is a second - type destination with imperfect charging facilities, ask if there is any other key device in the vehicle that can be used as a backup key for the mobile phone key. If there is, turn on the in - vehicle wireless charging device and charge the mobile phone battery to 80%, and then automatically stop charging; if not, turn on the in - vehicle wireless charging device and charge the mobile terminal until it is fully charged, and turn off the wireless charging device after it is fully charged. When there is no backup key, ensure that the mobile terminal, as the only legal key, has enough power to control the vehicle, avoiding the problem that the vehicle cannot be controlled by the mobile terminal due to power - off shutdown.

[0053] In summary, for the in-vehicle wireless charging control method provided in this application, during wireless charging by the user, different intelligent optimization controls are performed on the charging process according to the operating state of the in-vehicle wireless charging device. When the operating state is the on state, charging control is performed based on the initial battery level and the number of charging interruptions, ensuring different charging control strategies are adopted for different battery levels and different numbers of charging interruptions to protect the battery health during the charging process. When the operating state is the off state and the mobile terminal is a legitimate key, charging control is performed based on the initial battery level and the navigation destination. While retaining the user's original control habits, it ensures that the mobile terminal has a healthy battery level when the user reaches the navigation destination, and at the same time reduces the impact on the battery health during the charging process. By associating the wireless charging control process with the battery level and navigation of the mobile terminal, and considering factors such as whether the mobile terminal is a digital key device, intelligent charging control is performed to avoid damage to the mobile terminal battery during the wireless charging process, and at the same time to avoid the problem of insufficient mobile phone battery level after the user reaches the destination due to ignoring the actual state of the in-vehicle wireless charging device, thus improving the user experience of using in-vehicle wireless charging.

[0054] In some embodiments, as Figure 2 shown, charging control is performed on the mobile terminal according to the initial battery level and / or the number of charging interruptions when the mobile terminal is removed from the wireless charging position, including:

[0055] Step 201: In response to the initial battery level being less than a preset first battery level threshold, start timing when the mobile terminal is first located at the wireless charging position to obtain a charging timing duration, and perform stage charging control on the mobile terminal according to the charging timing duration and / or the number of charging interruptions.

[0056] In specific implementation, if the initial battery level is less than a preset first battery level threshold (for example, 50%), it indicates that the battery level of the mobile terminal is relatively low and there is a large charging demand. At this time, charging is given the highest priority. It is necessary to start timing when the mobile terminal is first located at the wireless charging position to obtain a charging timing duration, and use the charging timing duration and the number of charging interruptions to limit the charging process, avoiding the impact of frequent picking up and placing being ignored for a long time, accelerating the accumulation of battery damage, and at the same time ensuring that the battery has sufficient power for subsequent use.

[0057] Since the initial battery level is low, the charging time is long, and the real-time battery level of the mobile terminal will cross the first battery level threshold during the charging process, it is necessary to perform stage charging control on the mobile terminal according to the charging timing duration and / or the number of charging interruptions. The first stage corresponds to the stage where the charging timing duration is less than the first duration threshold, and the second stage corresponds to the stage where the charging timing duration is greater than or equal to the first duration threshold and less than the second duration threshold. Stage charging control can implement different control strategies at different battery levels, while taking into account the power consumption requirements and battery health protection.

[0058] Step 202: In response to the initial power being greater than or equal to a preset first power threshold and less than a preset second power threshold, if the number of charging interruptions is greater than or equal to a preset number threshold, stop charging the mobile terminal; if the number of charging interruptions is less than the preset number threshold, charge the mobile terminal when the mobile terminal is in the wireless charging position, and stop charging the mobile terminal when the real-time power of the mobile terminal is greater than or equal to the second power threshold.

[0059] In specific implementation, if the initial power is greater than or equal to a preset first power threshold and less than a preset second power threshold, it indicates that the battery power is relatively high and can ensure continuous use for a short period of time. Therefore, the charging requirement is relatively low. At this time, the balance point between frequent picking up and placing and charging can be comprehensively considered. This balance point can be represented by a number threshold, and the number threshold can be set to 3 times, 4 times or 5 times. Taking the number threshold of 3 times as an example for illustration.

[0060] If the initial power of the mobile terminal is in the range of [50%, 80%), it indicates that the charging requirement is relatively low at this time, and the focus is on protecting the battery health. If the number of charging interruptions is less than 3 times, it belongs to normal use and will not accelerate the accumulation of battery damage. Charge the mobile terminal when the mobile terminal is in the wireless charging position to meet the user's power demand, and stop charging the mobile terminal when the real-time power of the mobile terminal is greater than or equal to the second power threshold. When the power is sufficient for use, avoid the accumulation of damages caused by subsequent frequent picking up and placing, and protect the health of the battery.

[0061] If the number of charging interruptions is greater than or equal to 3 times, it indicates that the user frequently picks up and places the mobile phone at this time. In order to reduce the accumulation of damages, stop charging the mobile terminal by switching the operating state of the in-vehicle wireless charging device to the off state to protect the health of the battery.

[0062] Step 203: In response to the initial power being greater than or equal to a preset second power threshold, control the charging of the mobile terminal according to the navigation destination.

[0063] In specific implementation, if the initial power is greater than or equal to the second power threshold (for example, 80%), at this time, the user's mobile phone has sufficient power, and if the battery is frequently charged and interrupted at this time, it will affect the health of the mobile phone battery. At this time, if the user places the mobile phone in the wireless charging position, the charging will be controlled according to the navigation destination.

[0064] When the navigation destination is a first - type destination such as a company / home / mall where there are convenient charging facilities, the user can charge at any time in the first - type destination, and the mobile terminal is no longer charged to avoid the accumulation of damage to the battery caused by frequent charging and discharging. When the navigation destination is a second - type destination such as a suburb / mountain area where the charging facilities are not so perfect, in order to ensure that the user can use the mobile terminal without worry for a long time, the mobile terminal is continuously charged until it is fully charged to maximize the usage duration of the mobile terminal.

[0065] During specific implementation, such as Figure 3 shown, the mobile terminal is controlled for stage charging according to the charging timing duration and / or the number of charging and discharging times, including:

[0066] Step 301: In response to the charging timing duration being less than a preset first duration threshold, when the mobile terminal is located at the wireless charging position, the mobile terminal is charged, and the real - time battery level is determined. Charging stops when the real - time battery level is greater than or equal to a second battery level threshold.

[0067] During specific implementation, the first stage corresponds to the stage where the charging timing duration is less than the first duration threshold (T1), and the second stage corresponds to the stage where the charging timing duration is greater than or equal to the first duration threshold. When the charging timing duration is less than the preset first duration threshold, it belongs to the first stage of stage charging control. At this time, since the initial battery level is less than 50%, the battery level of the mobile terminal is relatively low, and there is a large charging demand. Charging the mobile terminal is the first priority to ensure that the user can use the mobile terminal for a long time. At this time, the impact of frequent picking up and placing on battery health can be ignored. Therefore, within the time when the charging timing duration is less than the preset first duration threshold, regardless of the number of charging and discharging times, the in - vehicle wireless charging device will remain in the on state to ensure that the user's mobile terminal has sufficient power for subsequent continuous use until the real - time battery level is greater than or equal to 80%. This indicates that the battery level is sufficient to support the long - time use of the mobile terminal. By switching the operating state, charging for the mobile terminal stops, and when the battery level drops below 50% again, charging for the mobile terminal is resumed by switching the operating state, and the timing of T1 is repeated. Because the battery level reaches 80% and is sufficient for the user to use continuously, and it can avoid the impact of frequent picking up and placing on the battery during subsequent charging, reducing the accumulation speed of damage to the battery caused by frequent picking up and placing to ensure the health of the battery.

[0068] Step 302: In response to the charging timing duration being greater than or equal to a preset first duration threshold, determine the end-of-phase power at the end of the first charging phase, and perform charging control for the second charging phase based on the end-of-phase power and the number of charging interruptions; wherein, the phase with a charging timing duration less than the first duration threshold is the first charging phase, the phase with a charging timing duration greater than or equal to the first duration threshold is the second charging phase, and the first charging phase and the second charging phase are consecutive charging phases.

[0069] In specific implementation, if the charging timing duration is greater than or equal to the preset first duration threshold, it enters the second stage of phase charging control. That is, after the end of time T1, if the end-of-phase power at the end of the first charging phase of the mobile terminal is less than 80%, start timing T2. Within time T2, if the user has three pick-up and put-down actions of the mobile phone, that is, the number of charging interruptions is greater than or equal to 3 times, it is considered that the user has a need to frequently use the mobile phone. At this time, stop charging until it is detected that the power < 50%, and then continue charging and re-time T1. If there is no pick-up and put-down action of the mobile phone after the end of T1, continue charging until the mobile phone power reaches 80%.

[0070] In some embodiments, such as Figure 4 shown, performing charging control for the second charging phase based on the end-of-phase power and the number of charging interruptions includes:

[0071] Step 401: In response to the end-of-phase power being less than a second power threshold, perform charging control based on the effective number of charging interruptions of the mobile terminal within a preset second duration threshold.

[0072] In some embodiments, performing charging control based on the effective number of charging interruptions of the mobile terminal within a preset second duration threshold includes:

[0073] Step 4011: In response to the effective number of charging interruptions being less than or equal to a preset number threshold, charge the mobile terminal when the mobile terminal is in the wireless charging position.

[0074] In specific implementation, after the end of time T1, if the end-of-phase power at the end of the first charging phase of the mobile terminal is less than 80%, start timing the second duration threshold (T2), and perform charging control for the second stage based on the effective number of charging interruptions of the mobile terminal within the preset second duration threshold, where the effective number of charging interruptions is the number of charging interruptions within time T2 after the start of the second charging phase.

[0075] If the number of effective charging interruptions within time T2 is less than or equal to a preset number threshold, it belongs to normal use and will not accelerate the accumulation of battery damage. When the mobile terminal is located at the wireless charging position, the mobile terminal is charged to meet the user's power demand, and when the real-time power of the mobile terminal is greater than or equal to the second power threshold, the charging of the mobile terminal is stopped. When the power is sufficient for use, it is possible to avoid the accumulation of damages caused by subsequent frequent picking up and placing, thus protecting the health of the battery.

[0076] Step 4012: In response to the number of effective charging interruptions being greater than the preset number threshold, stop charging the mobile terminal.

[0077] In specific implementation, if the number of effective charging interruptions is greater than or equal to 3 times, it indicates that the user frequently picks up and places the mobile phone at this time. In order to reduce the accumulation of damages at this time, the operation state of the in-vehicle wireless charging device is switched to the off state to stop charging the mobile terminal, so as to protect the health of the battery. Until it is detected that the power < 50%, charging continues and T1 is re-timed. If after T1 ends, the user does not pick up and place the mobile phone, charging continues until the mobile phone power reaches 80%. While ensuring sufficient power charging, it is possible to avoid the accumulation of damages caused by frequent picking up and placing.

[0078] Step 402: In response to the end-of-phase power being greater than or equal to the second power threshold, determine the location type of the navigation destination. If the location type is a preset first type of destination, stop charging the mobile terminal. If the location type is a preset second type of destination, stop charging the mobile terminal after charging to full power.

[0079] In specific implementation, if the initial power is greater than or equal to the second power threshold, at this time the user's mobile phone has sufficient power, and if the battery is frequently charged and interrupted at this time, it will affect the health of the mobile phone battery. At this time, if the user places the mobile phone at the wireless charging position, the charging control will be carried out according to the navigation destination.

[0080] If the navigation destination is a first type of destination such as a company / home / mall where there are convenient charging devices, the user can charge at any time in the first type of destination, so the charging of the mobile terminal is no longer carried out to avoid the accumulation of damages caused by frequent charging and interruption to the battery. If the navigation destination is a second type of destination such as a suburb / mountain area where the charging devices are not perfect, in order to ensure that the user can use the mobile terminal without worry for a long time, the mobile terminal continues to be charged until the mobile terminal is full of power.

[0081] Stage charging control can implement different control strategies at different powers, taking into account both the power consumption requirements and the protection of battery health.

[0082] In some embodiments, such as Figure 5As shown, charging control of the mobile terminal is performed according to the initial power and / or the navigation destination of the vehicle, including:

[0083] Step 501: In response to the initial power being greater than a preset first power threshold, keep the in-vehicle wireless charging device in the off state.

[0084] Specifically, if the initial power is greater than the preset first power threshold, it indicates that the power of the mobile terminal is sufficient for the user to use, there is no power anxiety, and there is no need to automatically switch the operating state of the in-vehicle wireless charging device. Just keep the in-vehicle wireless charging device in the off state.

[0085] Step 502: In response to the initial power being less than or equal to the preset first power threshold, determine the location type of the navigation destination.

[0086] Specifically, when implemented, if the initial power is less than or equal to the preset first power threshold, to determine the location type of the navigation destination, further charging requirement judgment needs to be made according to the location type of the navigation destination. If the navigation destination is a first-class destination such as a company / home / mall with convenient charging facilities, the user can charge at any time in the first-class destination, so the charging requirement in the vehicle is relatively low. To avoid the accumulation of damage to the battery caused by frequent charging and discharging, there is no need to automatically switch the operating state. If the navigation destination is a second-class destination such as a suburb / mountain area where the charging facilities are not perfect, the user cannot charge at any time in the second-class destination, so the charging requirement in the vehicle is relatively high. To avoid the mobile terminal shutting down due to too low power, it is necessary to automatically switch the operating state to charge the mobile terminal to ensure that the user can use the mobile terminal without worry for a long time.

[0087] Step 503: Detect the spare legal key other than the mobile terminal to obtain a detection result, and perform charging control according to the detection result and the location type.

[0088] In some embodiments, performing charging control according to the detection result and the location type includes:

[0089] Step 5031: In response to the location type being a preset first-class destination, keep the in-vehicle wireless charging device in the off state.

[0090] Specifically, when implemented, if the navigation destination is a first-class destination such as a company / home / mall with convenient charging facilities, the user can charge at any time in the first-class destination, so the charging requirement in the vehicle is relatively low. To avoid the accumulation of damage to the battery caused by frequent charging and discharging, there is no need to automatically switch the operating state.

[0091] Step 5032: In response to the location type being a preset second type of destination and the detection result being that a spare legal key is detected, turn on the in-vehicle wireless charging device to charge the mobile terminal, and stop charging the mobile terminal when the real-time power of the mobile terminal is greater than or equal to a preset second power threshold.

[0092] In specific implementation, if the navigation destination is a second type of destination such as a suburb / mountain area where charging facilities are not so perfect, the user cannot charge at any time in the second type of destination, so the charging demand in the vehicle is relatively high. To avoid the mobile terminal shutting down due to too low power, it is necessary to automatically switch the operating state to ensure that the user can use the mobile terminal without worry for a long time to charge the mobile terminal. At this time, it is necessary to further determine the conditions for stopping charging.

[0093] The condition for stopping charging needs to detect the spare legal key other than the mobile terminal. If the detection result is that a spare legal key is detected, it means that the user can control the vehicle with the spare legal key. At this time, mainly to protect the health of the battery, stop charging the mobile terminal when the real-time power of the mobile terminal is greater than or equal to a preset second power threshold, ensuring sufficient power while reducing the accumulation of damage caused by frequent picking up and placing.

[0094] Step 5032: In response to the location type being a preset second type of destination and the detection result being that no spare legal key is detected, turn on the in-vehicle wireless charging device to charge the mobile terminal, and stop charging the mobile terminal when the mobile terminal is fully charged.

[0095] In specific implementation, if the location type is a preset second type of destination and the detection result is that no spare legal key is detected, it means that the mobile terminal is the only legal key at this time, and the user can only use the mobile terminal to control the vehicle. When there is no spare key, ensure that the mobile terminal, as the only legal Bluetooth key, has enough power to control the vehicle, avoiding the problem that the vehicle cannot be controlled through the mobile terminal due to power shortage and shutdown.
