It is a relatively environmentally friendly charging method. However, when users sit in the front row of the vehicle, they are usually accustomed to placing their mobile phones on the wireless charging panel. When the mobile phone also has the wireless charging function, the mobile phone will start wireless charging. The user can only wait until the battery is fully charged. The user manually turns off the wireless charging function or moves the terminal device out of the wireless charging range to turn off the wireless charging. This situation may result in the user continuing to charge the mobile phone when he does not want to, which does not meet the user's needs, or the mobile phone continues to charge when the battery is greater than the recommended charging value, resulting in overcharging, which affects the battery life.

[0026] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.
[0027] The wireless charging technology involved in this application is described below.
[0028] The principle of wireless charging is to transfer electrical energy from one power source to another device through electromagnetic induction or electromagnetic radiation, thereby realizing the function of charging without the use of wires.
[0029] The principle of electromagnetic induction is to generate an alternating current at the transmitter to establish an alternating magnetic field between the transmitter and the receiver. When the receiver is placed near the transmitter, the coil inside the receiver will sense the alternating magnetic field and convert it into electrical energy for the device to use.
[0030] The principle of electromagnetic radiation is to generate a high-frequency electromagnetic field at the transmitter to radiate electrical energy in the form of radio waves. When the receiver is placed near the transmitter, the antenna inside the receiver will receive the radio waves and convert them into electrical energy for the device to use.
[0031] NFC is a short-range wireless communication technology. The working principle of the NFC module of a mobile terminal is to convert the transmitted information into an electrical signal through the NFC coil, so that the NFC reader can read the information of the mobile terminal.
[0032] NFC usually has three working modes: reading mode, writing mode and peer-to-peer mode. Reading mode is the most common mode. For example, as an example, a mobile phone can sense an NFC tag on a table and read the information carried in the tag; writing mode refers to writing information to an NFC tag on a personal computer, smartphone or portable electronic device; peer-to-peer mode refers to communication and transmission between two NFC-carrying devices.
[0033] According to the above working principle of NFC, the NFC coil and NFC controller are installed below the wireless charging panel of the vehicle, and the vehicle's computer system can read the information content in the car's NFC controller.
[0034] A method and device for controlling wireless charging in a vehicle according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.
[0035] Figure 11 is a flow chart of a method for controlling wireless charging in a vehicle provided in an embodiment of the present application. The method for controlling wireless charging in a vehicle in an embodiment of the present application can be executed by a cockpit domain controller (CDC) or by other controllers, such as an electronic control unit (ECU). This embodiment is described by taking the CDC as an example. Figure 1 As shown, the control method of wireless charging in the vehicle includes:
[0036] Step 101: receiving a terminal identification signal sent by a near field communication (NFC) controller, wherein the terminal identification signal includes target terminal information of a target terminal placed in a vehicle wireless charging device.
[0037] Specifically, the target terminal may be a mobile phone, a tablet computer, etc., which is not limited here.
[0038] When the NFC controller determines that the target terminal is placed on the vehicle wireless charging device, a terminal identification signal may be sent to the CDC. The terminal identification signal includes target terminal information of the target terminal, which is used to identify different terminals.
[0039] After receiving the terminal identification signal, the CDC can determine that the target terminal is placed in the vehicle wireless charging device according to the terminal identification signal and obtain the target terminal information.
[0040] The target terminal information may be an international mobile equipment identity code, a user-defined identifier pre-set by a user that can uniquely represent the identity of the target terminal, etc., which is not limited here.
[0041] Step 102: Determine a target wireless charging mode of the target terminal according to the target terminal information.
[0042] Specifically, the target wireless charging mode includes any one of a fast charging mode, a battery protection mode, a power control mode and a prohibited charging mode; wherein, the fast charging mode is to charge the battery of the target terminal using a preset power; the battery protection mode is to charge the target terminal using the preset power when the battery power of the target terminal is lower than a first preset threshold, and to charge the target terminal using a charging power less than the preset power when the battery power is not lower than the first preset threshold; the power control mode is to charge the target terminal in a fast charging mode or a battery protection mode when the battery power is lower than a second preset threshold, and to stop charging when the battery power reaches the second preset threshold; the prohibited charging mode is to not charge the target terminal.
[0043] Specifically, if the target wireless charging mode is a fast charging mode, the vehicle can increase the supply current or voltage to increase the power to a preset power, thereby increasing the charging speed and reducing the time required for charging.
[0044] In the battery protection mode, the first preset threshold value may be set by the system of the target terminal, such as 80%, 90%, etc. When the battery power is not less than the first preset threshold value, the preset power is used for charging, and when the battery power is less than the first preset threshold value, a lower power is used for charging, thereby reducing the impact on the battery life of the target terminal during the charging process by reducing the charging power.
[0045] In the power control mode, the second preset threshold value can be set by the system of the target terminal or by the user, for example, it can be 90%, 95%, etc. When the battery power is lower than the second preset threshold value, the fast charging mode or the battery protection mode can be used for charging, so that a variety of modes can be selected during the charging process, and the charging is stopped when the battery power reaches the second preset threshold value, so that the maximum charging value of the battery power of the target terminal can be controlled as needed by using the second preset threshold value as a sign of charging termination, so as to avoid the problem of reduced life due to continuous charging of the battery when the user forgets to turn off the wireless charging function.
[0046] In the charging prohibition mode, it is set not to charge the target terminal. When this mode is selected, the NFC wireless charging transmitter does not charge the target terminal, avoiding the problem that placing the terminal on the wireless charging device for automatic charging does not meet user needs.
[0047] In this way, by setting different wireless charging modes, the diversity of wireless charging modes is increased, the impact on the battery life of the target terminal during the charging process is reduced, and the safety of the charging process is enhanced; and by determining the target wireless charging mode of the target terminal based on the target terminal information, personalized mode selection of the terminal is achieved, meeting the different charging needs of users.
[0048] Step 103: According to the target wireless charging mode, control the target terminal to perform an operation corresponding to the target wireless charging mode.
[0049] Specifically, the control executes operations corresponding to the target wireless charging mode on the target terminal, so that it is possible to perform fast charging operations on the target terminal, reduce the power charging operation when the power reaches a certain value, stop charging operations when the power reaches a certain value, or not charge the terminal when it is placed on a wireless charging device. This realizes the terminal's various charging needs, avoids the problem that the user does not want to charge the terminal but the terminal is charged because it is placed on a wireless charging device, and can avoid the problem of overcharging the terminal.
[0050] According to the technical solution provided in the embodiment of the present application, the target terminal information of the target terminal is identified by the NFC controller, and the information is forwarded to the CDC controller. The CDC controller determines the target wireless charging mode of the target terminal by analyzing the target terminal information forwarded by the NFC controller, and then the CDC controller controls the target terminal to perform operations corresponding to the target wireless charging mode, thereby realizing the selection of personalized charging modes for the terminal, enhancing the applicability in multi-scenario and multi-functional situations, avoiding the result of overcharging caused by continuous charging when the terminal power is greater than the recommended charging value, extending the battery life of the target terminal, and meeting the diverse charging needs of users.
[0051] In some embodiments, determining a target wireless charging mode of the target terminal according to the target terminal information includes:
[0052] In the case of detecting that the target terminal information has been received historically, determining the number of historical acquisitions of the target terminal information;
[0053] First, when the number of historical acquisition times is equal to 1, the wireless charging mode determined when the target terminal information is historically acquired is determined as the target wireless charging mode.
[0054] Specifically, the number of historical acquisition times refers to the number of times the target terminal is identified and the terminal information is read on the NFC controller, which is used to determine whether the target terminal has historical charging information. The historical charging information can be used as a basis to determine the target wireless charging mode, simplifying the process of determining the target wireless charging mode.
[0055] In addition, when the number of historical acquisitions is 1, the wireless charging mode corresponding to the target terminal information when the target terminal information is historically acquired can be directly determined as the target wireless charging mode. For example, as an example, the CDC controller detects that the target terminal information has been received once in history, and during the historical charging process, the wireless charging mode of the target terminal is the fast charging mode. When the target terminal information is received this time, the fast charging mode is determined as the target wireless charging mode of the target terminal this time, that is, the target terminal performs the charging process in the fast charging mode this time.
[0056] In this way, when the number of historical acquisitions is 1, the wireless charging mode determined last time is directly determined as the target wireless charging mode for this wireless charging, so that the target wireless charging mode is more likely to meet the user's needs, and the process of the user selecting the wireless charging mode is avoided, thereby improving the convenience of determining the wireless charging mode.
[0057] Second, when the number of historical acquisitions is greater than or equal to 2, then:
[0058] The wireless charging mode corresponding to the target terminal information obtained most recently is determined as the target wireless charging mode; or, the wireless charging mode corresponding to the target terminal information obtained most recently N times is determined; the wireless charging mode that appears most frequently among the corresponding wireless charging modes for the N times is determined as the target wireless charging mode, and when the wireless charging mode that appears most frequently is greater than or equal to 2, the wireless charging mode that is most recently used among the wireless charging modes that appear most frequently is determined as the target wireless charging mode, wherein N is greater than or equal to 2.
[0059] Specifically, the target terminal information obtained at the most recent time refers to the target terminal information obtained most recently before the current time, and the wireless charging mode corresponding to the target terminal information obtained at the most recent time refers to the wireless charging mode determined when the target terminal information was received historically. When the number of historical acquisitions is greater than or equal to 2, the corresponding wireless charging mode can be determined as the target wireless charging mode of the target terminal this time.
[0060] For example, as an example, the number of historical acquisitions is equal to 2, and the CDC controller detects that the wireless charging mode of the target terminal at the first historical time is the fast charging mode, and the wireless charging mode at the second historical time is the power control mode. The first historical time is close to the current time, so the fast charging mode is determined as the target wireless charging mode of the target terminal this time, that is, the target terminal is charged in the fast charging mode this time. In this way, the user's recent charging needs are used as the standard for determining the wireless charging mode, which can better meet the needs of users.
[0061] In addition, when the number of historical acquisitions is greater than or equal to 2, the wireless charging modes determined in each of the most recent N charging records can also be obtained, and the wireless charging mode with the most repeated uses can be determined as the target wireless charging mode for the target terminal this time. In this way, the wireless charging mode with the most repeated uses can be considered to be the user's need. Therefore, by determining the wireless charging mode with the most repeated uses as the target wireless charging mode for the target terminal this time, the user's charging needs can be better met.
[0062] In addition, if the wireless charging mode that appears most frequently in N times is greater than or equal to 2, the wireless charging mode used most recently can be determined as the target wireless charging mode of the target terminal this time, thereby avoiding the situation where the determination cannot be made when there are multiple wireless charging modes that appear most frequently. Moreover, since the wireless charging mode used most recently can better represent the user's current charging needs, the probability that the determined target wireless charging mode meets the user's charging needs is increased.
[0063] For instance, as an example, the number of historical acquisitions is 6 and N is 4, and the CDC controller detects that in the last 4 historical charging processes, the target terminal used the fast charging mode as the wireless charging mode 3 times, then the fast charging mode is determined as the target wireless charging mode for this time. If the target terminal used the fast charging mode and the battery protection mode as the wireless charging mode 2 times in the last 4 historical charging processes, and the most recently used wireless charging mode of the two modes is the fast charging mode, then the CDC controller determines the fast charging mode as the target wireless charging mode, that is, the target terminal performs the charging process in the fast charging mode this time.
[0064] According to the technical solution provided in the embodiment of the present application, by obtaining the historical number of acquisitions of the target terminal information, the target wireless charging mode is determined in a corresponding manner, thereby simplifying the process of determining the target wireless charging mode and meeting the charging needs of the user.
[0065] In some embodiments, after receiving the terminal identification signal sent by the NFC controller, the method further includes:
[0066] When the target terminal information is detected to be received for the first time, a charging mode setting interface is displayed on the central control screen of the vehicle, wherein the charging mode setting interface displays a fast charging mode, a battery protection mode, a power control mode and a charging prohibition mode;
[0067] In response to a first selection operation of a user for any mode, the mode corresponding to the first selection operation is determined as a target wireless charging mode.
[0068] Specifically, the central control screen refers to the display screen on the center console of the vehicle, which is used for displaying information or touch operation for human-vehicle interaction.
[0069] The charging mode setting interface is displayed on the central control screen, which is used to provide the user with the command selection for wireless charging mode setting, such as Figure 2 As shown, the central control screen displays wireless charging options, including fast charging mode, battery protection mode, power control mode and charging prohibition mode. After the CDC controller receives the terminal identification signal, if it detects that it is the first time to receive the target terminal information, it controls the display of the charging mode setting interface. It should be noted that when the control displays the charging mode setting interface, a voice prompt message can be issued to prompt the user to select the desired wireless charging mode on the charging mode setting interface.
[0070] It should be noted that while displaying the wireless charging option, it can also display "Please select the charging mode (turning on charging means you agree that the car machine can obtain your terminal power)", and the following displays four specific wireless charging modes, including: fast charging mode, in the fast charging mode option, it can be supplemented with "turning on this mode means you turn on the car machine's permission to read your terminal model and battery parameters"; battery protection mode, in the battery protection mode option, it can be supplemented with "turning on this mode will reduce the charging rate when the power reaches 80%"; power control mode, in the power control mode option, it can be supplemented with "turning on this mode will turn off wireless charging when the power reaches the value you set"; and prohibit charging mode. This allows users to enhance their understanding of the charging mode based on the displayed information.
[0071] The first selection operation is a selection instruction input by the user for each of the above wireless charging modes, and the first selection operation can be a voice input operation or a touch selection operation. After receiving the first selection operation, the CDC controller determines the corresponding wireless charging mode as the target wireless charging mode for this time, thereby realizing the setting of the wireless charging mode according to the user's needs.
[0072] According to the technical solution provided in the embodiment of the present application, a user can manually set the desired target wireless charging mode, so that the set target wireless charging mode is the wireless charging mode desired by the user, thereby satisfying the user's demand for wireless charging.
[0073] In some embodiments, after determining the target wireless charging mode of the target terminal according to the target terminal information, the method further includes:
[0074] Receiving a modification instruction input by a user, wherein the modification instruction is used to instruct to modify a target wireless charging mode;
[0075] According to the modification instruction, the charging mode setting interface is displayed on the central control screen of the vehicle;
[0076] In response to a second selection operation of the user for any wireless charging mode, the mode corresponding to the second selection operation is determined as a target wireless charging mode.
[0077] Specifically, the modification instruction input by the user refers to the operation instruction input by the user when changing the target wireless charging mode as required after the CDC controller determines the target wireless charging mode. It should be noted that when the user needs to modify the target wireless charging mode, the modification instruction can be input by touching the central control screen or by voice wake-up.
[0078] The second selection operation is used to modify the currently determined target wireless charging mode. After receiving the modification instruction, the CDC controller controls the display of the charging mode setting interface and receives the user's second selection operation for the required wireless charging mode, thereby re-determining the target wireless charging mode.
[0079] For instance, as an example, the CDC controller determines that the target wireless charging mode is a fast charging mode based on the target terminal information. When the user wants to change it to a battery protection mode, the user can input a modification instruction through the central control screen, and the charging mode setting interface is displayed on the central control screen. The user can select a battery protection mode in the charging mode setting interface. The CDC controller responds to the selection operation and determines the corresponding battery protection mode as the new target wireless charging mode.
[0080] According to the technical solution provided in the embodiment of the present application, by receiving the modification instruction input by the user, the charging mode setting interface is controlled to be displayed on the central control screen, and the user selects any optional mode on the charging mode setting interface. The CDC controller responds to the selection instruction and uses the corresponding wireless charging mode as the new target wireless charging mode, so that when the target wireless charging mode determined according to the target terminal information does not meet the user's needs, the user can modify the charging mode, thereby ensuring that the final determined charging mode meets the user's charging needs and enhancing the flexibility of switching the target wireless charging mode.
[0081] In some embodiments, according to the target wireless charging mode, controlling the target terminal to perform an operation corresponding to the target wireless charging mode includes:
[0082] If the target wireless charging mode is a fast charging mode, a battery protection mode or a power control mode, a first indication signal is sent to the NFC controller, and the first indication signal is used to instruct the NFC controller to obtain parameter information related to battery charging of the target terminal, so that the NFC controller sends the parameter information to the battery management system BMS after obtaining the parameter information, and the BMS determines the charging power according to the parameter information and the target wireless charging mode, and charges the target terminal according to the charging power through the NFC controller;
[0083] If the target wireless charging mode is the prohibited charging mode, a second indication signal is sent to the NFC controller, where the second indication signal is used to instruct the NFC controller to prohibit obtaining parameter information related to battery charging of the target terminal.
[0084] Specifically, the parameter information related to battery charging includes the power level, model and battery parameters of the target terminal.
[0085] If the target wireless charging mode is fast charging mode, battery protection mode or power control mode, it means that the target terminal needs to be charged, so it is necessary to read the parameter information related to battery charging of the target terminal. After receiving the first indication signal, the NFC controller can read the parameter information. At this time, the target terminal sends the parameter information to the NFC controller in the near field communication data exchange format (NFC Data Exchange Format, NDEF) format, and the NFC controller forwards the parameter information to the battery management system (Battery Management System, BMS).
[0086] The BMS can receive the target wireless charging mode sent by the CDC, and can determine the charging power with reference to the target wireless charging mode and the parameter information, and send the charging power to the NFC controller, so that the NFC controller can control the NFC wireless charging transmitter to adjust the voltage or current to the charging power, thereby charging the target terminal with the corresponding charging power, that is, with the corresponding target wireless charging mode.
[0087] For example, in fast charging mode, according to the charging power calculation method: P=UI=I*I*R=U*U / R, where P is the charging power, U is the charging voltage, I is the charging current, and R is the resistance of the target terminal battery, the NFC wireless charging transmitter is controlled to increase the current or voltage to increase the charging power to the preset power, thereby realizing charging in fast charging mode and increasing the charging speed.
[0088] In battery protection mode, for example, the first preset threshold is 80%, then when the battery level of the target terminal is less than 80%, the NFC wireless charging transmitter is controlled to charge using the preset power; when the battery level is greater than or equal to 80%, the NFC wireless charging transmitter is controlled to reduce the charging current or charging voltage to reduce the charging power, thereby reducing the impact on the battery life of the target terminal.
[0089] In the power control mode, for example, the second preset threshold is 70%, when the battery power of the target terminal is less than 70%, the NFC wireless charging transmitter is controlled to charge according to the selected fast charging mode or battery protection mode. When the power is greater than or equal to 70%, the NFC wireless charging transmitter is controlled to stop charging, thereby avoiding continuous charging when the battery power is higher than the set charging threshold.
[0090] In addition, if the target wireless charging mode is a prohibited charging mode, that is, the target terminal is not charged when placed on the wireless charging device, a second indication signal can be sent to the NFC controller to instruct the NFC controller not to perform the parameter information acquisition process, thereby avoiding the problem of wasting resources by invalidly acquiring parameter information.
[0091] According to the technical solution provided in the embodiment of the present application, it is implemented to distinguish whether to obtain parameter information related to battery charging of the target terminal according to the charging mode, so that the parameter information is obtained only when there is a charging demand, and is not obtained when charging is not in progress, thereby avoiding the invalidity of parameter information caused by obtaining parameter information in any mode and avoiding waste of resources.
[0092] In some embodiments, when the target wireless charging mode is the power control mode,
[0093] According to the target wireless charging mode, before controlling the target terminal to perform an operation corresponding to the target wireless charging mode, the method further includes:
[0094] Controlling the vehicle's central control screen to display a power control setting interface, wherein the power control setting interface displays a fast charging mode, a battery protection mode, and a second preset threshold setting item;
[0095] In response to a user input operation on a second preset threshold setting item, determining a numerical value corresponding to the input operation as the second preset threshold;
[0096] In response to a third selection operation of the user on the fast charging mode or the battery protection mode, charging is performed according to the mode selected by the third selection operation when the battery power is lower than the second preset threshold.
[0097] Specifically, the second preset threshold is used to limit the maximum amount of power charged in the power control mode, and when the battery power of the target terminal is greater than or equal to the second preset threshold, charging is stopped.
[0098] like Figure 3 As shown, if the target wireless charging mode is determined to be the power control mode, the power control setting interface can be controlled to be displayed on the central control screen, and the power control setting interface displays the fast charging mode, battery protection mode and the second preset threshold setting items. It should be noted that when the power control setting interface is displayed, a voice message can also be issued to prompt the user to set the charging mode and power threshold in the power control mode.
[0099] The input operation is used to determine the second preset threshold value, and the input operation can be inputting a specific value or a selection operation of multiple values set in the interface. After receiving the input operation, the CDC controller can determine the value corresponding to the input operation as the second preset threshold value, so that it can be determined whether charging needs to continue according to the second preset threshold value.
[0100] The third selection operation is used to select a charging mode during the charging process, which may be a fast charging mode or a battery protection mode. After receiving the third selection operation, the CDC controller may set the charging mode corresponding to the third selection operation to a charging mode when the battery power is lower than a second preset threshold in the power control mode, so that when the battery power is lower than the second preset threshold, charging is performed in accordance with the mode selected by the third selection operation.
[0101] It should also be noted that, in the power control mode, after the target terminal battery power reaches the second preset threshold and stops charging, the following steps are also included:
[0102] Sending a charging completion prompt message to the user to prompt the user that the target terminal has completed charging.
[0103] The prompt information may be voice, music, flashing light or vibration, etc., which is not limited here.
[0104] For example, as an example, Figure 3 As shown, the user touches to select the fast charging mode in the power control setting interface displayed on the central control screen, and enters 90% as the second preset threshold in the second preset threshold setting item, that is, as the upper limit of the charging power control. When the battery power of the target terminal is less than 90%, charging is performed in the fast charging mode. When the battery power of the target terminal reaches 90%, the charging process is terminated, and a voice prompt is sent to the user to indicate that the charging process of the target terminal is over.
[0105] According to the technical solution provided in the embodiment of the present application, by controlling the vehicle's central control screen to display the power control setting interface, the user touches the central control screen to select the wireless charging mode required for this charging process, and at the same time displays the second preset threshold setting item. The user enters the required charging upper limit in the setting item. After completing these selections and inputting instructions, the power control mode setting is completed, allowing the user to select the charging mode and charging upper limit according to their own charging needs, thereby increasing the degree of personalization of the charging mode.
[0106] In some embodiments, if the target wireless charging mode is a fast charging mode, a battery protection mode, or a power control mode, after controlling the target terminal to perform an operation corresponding to the target wireless charging mode according to the target wireless charging mode, the method further includes:
[0107] Obtain the current battery power and driving navigation information of the target terminal;
[0108] According to the driving navigation information, the charging increment of the battery power is predicted;
[0109] Based on the current battery power and the charging increment, the battery power at the end of the vehicle journey is predicted;
[0110] According to the battery power at the end of the vehicle journey, power prompt information is output, wherein the power prompt information is used to prompt the battery power at the end of the journey.
[0111] Specifically, driving navigation information refers to relevant information about the vehicle's current trip, including but not limited to destination information, mileage information, estimated driving time, etc.
[0112] The charging increment refers to the additional charging amount that the target terminal can achieve during the driving process indicated by the navigation information. When determining the charging increment, it can be determined based on the remaining time of the trip corresponding to the start of charging and the charging speed.
[0113] The battery reminder information can be voice, text, etc., and is not limited here.
[0114] For example, the current battery level of the mobile phone is 20%, and the remaining time for the journey when charging starts is 30 minutes. In fast charging mode, the charging increment of the mobile phone battery that can be obtained in 30 minutes is 70%. According to the estimated results, after the journey indicated by this navigation is completed, the battery level of the mobile phone can reach 100%, and a voice prompt message will be sent to the user.
[0115] According to the technical solution provided in the embodiment of the present application, the current power of the target terminal and the navigation information prompted by the driving navigation are used to predict the battery charging increment in the target wireless charging mode during this navigation process. The battery power after the trip is estimated based on the current power and the charging increment, and this result is sent to the user in the form of a prompt message, thereby realizing the estimation of the charging amount during the charging process, allowing the user to understand in advance the charging status of the target terminal at the end of the trip, thereby improving the user experience.
[0116] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described one by one here.

[0118] The NFC controller reads the target terminal information when detecting that the target terminal is placed in the vehicle wireless charging device, and sends a terminal identification signal carrying the target terminal identification information to the CDC controller;
[0119] The CDC controller receives the target terminal identification information and determines the target wireless charging mode according to the target terminal identification information; or controls the central control large screen to display the charging mode setting interface, so that the user can select or modify the charging mode; in addition, when the target wireless charging mode is the power control mode, the power control setting interface is displayed, so that the user can set the charging mode and the upper charging limit threshold in the power control mode; then the determined target wireless charging mode is sent to the BMS, and when the determined target wireless charging mode is the non-prohibited charging mode, the NFC controller is notified to read the charging-related parameter information of the target terminal;
[0120] The central control screen can receive input commands from the user and display relevant setting interfaces to the user.
[0121] The NFC controller reads the parameter information and sends it to the BMS.

The NFC controller controls the NFC wireless charging transmitter to adjust the charging current or charging voltage to achieve the charging power, thereby realizing charging in the target wireless charging mode. Specifically, the wireless charging transmitter performs a charging process under corresponding conditions, and the process is controlled by the specific information sent by the BMS.
[0122] According to the technical solution provided in the embodiment of the present application, the target terminal information is identified by the NFC controller, and a signal is sent to the CDC controller. The CDC controller controls the central control screen to display the wireless charging setting interface to the user. After the user manually enters the command, the corresponding target wireless charging mode information is sent to the BMS according to the command signal. The BMS obtains the corresponding control current, voltage and power-on time information through analysis, and sends the information as a command to the wireless charging transmitter. The target terminal is charged according to the command requirements through the wireless charging transmitter, thereby realizing the patternization of wireless charging, improving the accuracy of charging requirements, enhancing the safety of the charging process, and ensuring the service life of the terminal battery.
