[0049] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0050] The technical solutions provided by various embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings.

[0051] Figure 1 is a flow chart of a charging control method according to an exemplary embodiment. Figure 1 ,like Figure 1 As shown, the charging control method provided by the embodiment of the present disclosure may at least include the following steps:

[0052] Step 110: Acquire positional offset data between a wireless charging device and a terminal device charged by the wireless charging device, wherein the positional offset data is used to characterize a degree of positional offset between the wireless charging device and the terminal device;

[0053] Step 120: Determine a target charging parameter of the wireless charging device based on the offset data;

[0054] Step 130: Control the wireless charging device to transmit a charging signal to the terminal device based on the target charging parameter.

[0055] In the disclosed embodiment, the charging control method may be executed by an electronic device, which may be the terminal device or an independent device that simultaneously establishes a communication connection with the terminal device and the wireless charging device. For example, the electronic device may be another mobile phone that establishes a communication connection with a mobile phone that is charged by the wireless charging device.

[0056] The terminal device may be a mobile communication terminal, a user device, a mobile device, or other device supporting wireless charging technology, etc. It should be noted that the specific type of the terminal device is not limited in the embodiments of the present disclosure.

[0057] Here, the embodiments of the present disclosure are applicable to scenarios where a terminal device supporting wireless charging, such as a mobile phone, performs high-power wireless charging with a wireless charging device whose position is not restricted by snaps or magnets.

[0058] For example, Figure 2a As shown, the wireless charging device 1 can be designed as a disc, and the position of the terminal device 2 such as a mobile phone placed on the wireless charging device 1 can be freely controlled up, down, left, and right, and the placement of the mobile phone depends entirely on the user's subjective feeling. In this case, it is easy to cause position deviation; Figure 2b As shown, the wireless charging device 1 can be designed to be vertical, and the terminal device 2 can be moved in two directions, and it is easy to be displaced in the two directions.

[0059] like Figure 2c As shown, the ideal state of the wireless charging device for wirelessly charging the terminal device is that the coil of the wireless charging device is completely aligned with the coil of the terminal device. Such a relative position has good coupling, high efficiency and low heat loss. In the actual wireless charging process, it is impossible for the coil of the wireless charging device to be exactly aligned with the coil of the terminal device at each charging position, and there will be more or less offset. After verification by a large amount of historical data, when the offset is within a radius less than or equal to 5 millimeters (mm) with the coil center of the above-mentioned wireless charging device as the center of the circle, that is, the offset distance between the above-mentioned terminal device and the above-mentioned wireless charging device is less than or equal to 5mm, the above-mentioned terminal device can be charged at the rated power of the above-mentioned wireless charging device; when the offset is within a radius greater than 5mm and less than or equal to 10mm with the coil center of the above-mentioned wireless charging device as the center of the circle, that is, the offset distance between the above-mentioned terminal device and the above-mentioned wireless charging device is greater than 5mm and less than or equal to 10mm, the charging efficiency of the above-mentioned terminal device decreases, the heat loss increases, and even charging is disconnected; and when the offset is within a radius greater than 10mm with the coil center of the above-mentioned wireless charging device as the center of the circle, that is, the offset distance between the above-mentioned terminal device and the above-mentioned wireless charging device is greater than 10mm, the above-mentioned terminal device cannot be wirelessly charged.

[0060] In step 110, the above-mentioned offset data may be data representing the position alignment between the above-mentioned terminal device and the above-mentioned wireless charging device, that is, the degree of position offset between the above-mentioned terminal device and the above-mentioned wireless charging device is 0; or, the above-mentioned offset data may be data representing the offset between the above-mentioned terminal device and the above-mentioned wireless charging device, that is, the degree of position offset is greater than 0.

[0061] Among them, as an example, the degree of position offset between the above-mentioned terminal device and the above-mentioned wireless charging device may refer to the displacement between the coil center of the above-mentioned wireless charging device and the coil center of the above-mentioned terminal device; for example, the offset distance between the above-mentioned terminal device and the above-mentioned wireless charging device may be the relative distance between the coil center of the above-mentioned wireless charging device and the coil center of the above-mentioned terminal device.

[0062] For example, the above-mentioned offset data may include but is not limited to the current signal strength mapping value (Signal Strength, SS) between the above-mentioned terminal device and the above-mentioned wireless charging device, and the signal strength mapping value is negatively correlated with the above-mentioned position offset degree, that is, the greater the position offset degree between the above-mentioned terminal device and the above-mentioned wireless charging device, the smaller the corresponding signal strength mapping value; or, the above-mentioned offset data may also be the offset distance between the above-mentioned terminal device and the above-mentioned wireless charging device; and so on.

[0063] Here, the signal strength mapping value can be obtained in the interaction between the terminal device and the wireless charging device based on the protocol specified in the wireless charging standard (Qi standard) proposed by the Wireless Power Consortium (WPC); and the offset distance can be obtained by adding a displacement sensor to the terminal device for detection, and the relative distance between the coil center of the terminal device and the coil center of the wireless charging device, that is, the offset distance, is detected by the displacement sensor.

[0064] Among them, the Qi standard is a wireless charging standard with two major characteristics: convenience and versatility. Its principle is to transfer energy into electrical energy through the transmitting and receiving antennas, and use the principle of electromagnetic induction for wireless charging. The Qi standard can include four stages: selection stage, ping stage, identification and configuration stage, and power transfer stage.

[0065] It can be understood that the relative distance between the coil center of the above-mentioned terminal device and the coil center of the above-mentioned wireless charging device is different, that is, the degree of position offset between the two is different, resulting in different above-mentioned offset data; that is, the above-mentioned offset data can be used to characterize the degree of position offset between the above-mentioned terminal device and the above-mentioned wireless charging device.

[0066] In step 120, the target charging parameter may be a limiting parameter for the wireless charging device to wirelessly charge the terminal device. For example, the target charging parameter may include a target power, a target charging voltage, a target charging current, or the like.

[0067] Here, when the above-mentioned target charging parameter is the target power, for example, 30 watts (W), the power of the above-mentioned wireless charging device for wireless charging the above-mentioned terminal device cannot exceed 30W; when the above-mentioned target charging parameter is the target charging voltage, for example, 20 volts (V), the voltage of the above-mentioned wireless charging device for wireless charging the above-mentioned terminal device cannot exceed 20V; when the above-mentioned target charging parameter is the target charging current, for example, 5 amperes (A), the current of the above-mentioned wireless charging device for wireless charging the above-mentioned terminal device cannot exceed 5A; and so on.

[0068] In the embodiment of the present disclosure, determining the target charging parameters of the wireless charging device based on the offset data in step 120 may specifically include: determining the target charging parameters based on the current signal strength mapping value and the first signal strength threshold value; or, determining the target charging parameters based on the current signal strength mapping value and a pre-trained machine learning model; or, determining the target charging parameters based on the offset distance and the first offset threshold value; and so on.

[0069] It should be noted that the specific method for determining the target charging parameter can be set according to the actual application situation, and the embodiments of the present disclosure do not limit it. For example, the target charging parameter corresponding to the above-mentioned offset data can be found by looking up the mapping relationship table; or, the target charging parameter corresponding to the above-mentioned offset data can be determined by using a function; or, the above-mentioned offset data can be input into a pre-trained machine learning model by using a machine learning model, and the target charging parameter corresponding to the offset data can be output; and so on.

[0070] In step 130, the charging signal may be a signal transmitted by the terminal device to control the wireless charging device.

[0071] It should be noted that the parameter value corresponding to the above-mentioned charging signal can be determined based on the above-mentioned target charging parameter, and the parameter value corresponding to the above-mentioned charging signal can be less than or equal to the above-mentioned target charging parameter.

[0072] In the disclosed embodiment, the terminal device may send a control instruction to the wireless charging device, and the control instruction may instruct the wireless charging device to transmit a charging signal to the terminal device based on the target charging parameters so as to charge the terminal device.

[0073] Here, the control instruction can be sent to the above-mentioned wireless charging device based on, for example, 1.5 seconds per time. Each control instruction sent can carry data for adjusting or not adjusting the above-mentioned charging signal to determine the charging signal emitted by the above-mentioned wireless charging device to the above-mentioned terminal device.

[0074] In one embodiment of the present disclosure, if the target charging parameters of the wireless charging device determined at the current moment are different from the target charging parameters of the wireless charging device determined at the previous moment, it means that the target charging parameters of the wireless charging device are adaptively adjusted at the current moment. At this time, the electronic device can issue a notification reminder of the misalignment between the terminal device and the wireless charging device to remind the user to adjust the position between the terminal device and the wireless charging device.

[0075] It should be noted that the time for the above-mentioned electronic device to send out the notification reminder for the misalignment between the terminal device and the wireless charging device can be set according to the actual application situation, and the embodiments of the present disclosure do not limit it. For example, the issuance time of the notification reminder can be carried out at the same time as the adjustment of the target charging parameters; or, the notification reminder can be issued after the adjustment of the target charging parameters; or, the notification reminder can be issued before the adjustment of the target charging parameters.

[0076] The charging control method provided by the embodiment of the present disclosure obtains the displacement data between the wireless charging device and the terminal device charged by the wireless charging device, and the displacement data is used to characterize the degree of position displacement between the wireless charging device and the terminal device; based on the displacement data, the target charging parameters of the wireless charging device are determined; and the wireless charging device is controlled to transmit a charging signal to the terminal device based on the target charging parameters. In other words, when the degree of position displacement between the terminal device and the wireless charging device is different, the displacement data will be different, and then the target charging parameters determined based on the displacement data will also be different. In this way, when a displacement occurs between the terminal device and the wireless charging device, the embodiment of the present disclosure can automatically adapt to the displacement and adjust the maximum charging power of the wireless charging device to the terminal device, so as to improve the charging efficiency and reduce the heating of the terminal device during the charging process.

[0077] In one embodiment of the present disclosure, step 120 may be implemented in various ways.

[0078] A specific implementation example is given below, and the offset data in the embodiment of the present disclosure may include: the current signal strength mapping value between the terminal device and the wireless charging device. It should be noted that the following is only an example and is not intended to be limiting.

[0079] Figure 3 Schematic diagram 2 of a charging control method provided by an embodiment of the present disclosure. Figure 3 , step 120 in the charging control method provided in the embodiment of the present disclosure may include the following steps:

[0080] Step 121, determining the rated charging parameters of the wireless charging device;

[0081] Step 122: When the current signal strength mapping value is greater than the first signal strength threshold value, use the rated charging parameter of the wireless charging device as the target charging parameter;

[0082] Step 123: When the current signal strength mapping value is less than or equal to the first signal strength threshold value, use the charging parameter corresponding to the current signal strength mapping value as the target charging parameter.

[0083] In the disclosed embodiment, the signal strength mapping value may represent a quantified value of the coupling strength state between the coil of the terminal device and the coil of the wireless charging device; and the current signal strength mapping value may be a signal strength mapping value between the terminal device and the wireless charging device at the current moment.

[0084] In step 121, the rated charging parameter may include the rated power, rated charging voltage or rated charging current of the wireless charging device; for example, the rated charging parameter may be a rated power of 50W or a rated power of 30W of the wireless charging device.

[0085] In step 122, the first signal strength threshold value may be a critical value at which the charging parameters of the wireless charging device for charging the terminal device need to be adjusted; for example, the first signal strength threshold value may be a signal strength mapping value corresponding to an offset distance of 5 mm between the wireless charging device and the terminal device.

[0086] It can be understood that based on the negative correlation between the signal strength mapping value and the degree of position deviation, the current signal strength mapping value greater than the first signal strength threshold value can indicate that there is no deviation between the terminal device and the wireless charging device. At this time, the terminal device can be charged with the rated charging parameters of the wireless charging device, thereby ensuring the charging efficiency of the wireless charging device to the terminal device.

[0087] In one embodiment of the present disclosure, the process of pre-acquiring the first signal strength threshold value may specifically include:

[0088] Based on the offset sampling distance between the terminal device and the wireless charging device, acquiring a plurality of sampling signal strength mapping values ​​corresponding to the offset sampling distance;

[0089] The plurality of sampled signal strength mapping values ​​are processed to obtain the first signal strength threshold value corresponding to the offset sampling distance.

[0090] In this way, the first signal strength threshold value corresponding to an offset sampling distance can be obtained by processing multiple sampled signal strength mapping values ​​corresponding to the offset sampling distance, so that the offset distance between the wireless charging device and the terminal device can be better characterized by the signal strength mapping value.

[0091] The offset sampling distance may be the spacing distance between the coil center of the terminal device and the coil center of the wireless charging device. For example, the offset sampling distance may be 5 mm.

[0092] The sampling signal strength mapping value may be a quantified value of the coupling strength state between the coil of the terminal device and the coil of the wireless charging device when the distance between the two is the offset sampling distance.

[0093] In one embodiment of the present disclosure, the processing of the plurality of sampled signal strength mapping values ​​to obtain the first signal strength threshold value corresponding to the offset sampling distance may specifically include:

[0094] Deduplication is performed on a plurality of the sampled signal strength mapping values ​​to obtain the deduplicated sampled signal strength mapping values;

[0095] The sampled signal strength mapping values ​​after deduplication are added and averaged to obtain the first signal strength threshold value.

[0096] In this way, the first signal strength threshold value can be obtained by performing deduplication, addition and averaging operations on multiple sampled signal strength mapping values, thereby improving the accuracy of determining the target charging parameter of the wireless charging device.

[0097] In step 123, the charging parameter corresponding to the current signal strength mapping value may be obtained by looking up a mapping relationship table, using a function, or using a machine learning model.

[0098] In the disclosed embodiment, step 123 may specifically include: based on the mapping relationship between the preset signal strength mapping value and the charging parameter, taking the charging parameter corresponding to the above-mentioned current signal strength mapping value as the above-mentioned target charging parameter; or, based on a preset function and the above-mentioned current signal strength mapping value, calculating to obtain the charging parameter corresponding to the above-mentioned current signal strength mapping value, and taking the charging parameter as the above-mentioned target charging parameter; or, based on a pre-trained machine learning model, inputting the above-mentioned current signal strength mapping value into the pre-trained machine learning model, outputting the charging parameter corresponding to the above-mentioned current signal strength mapping value, and taking the charging parameter as the above-mentioned target charging parameter.

[0099] The charging control method provided by the embodiment of the present disclosure can determine the target charging parameters of the wireless charging device through the signal strength mapping value between the terminal device and the wireless charging device and the pre-acquired first signal strength threshold value, so as to judge the misalignment between the terminal device and the wireless charging device by comparing the signal strength mapping value with the first signal strength threshold value, so as to adjust the target charging parameters of the wireless charging device for the terminal device, improve the charging efficiency, and reduce the heat generation of the terminal device during the charging process.

[0100] In one embodiment of the present disclosure, step 123 may be implemented in various ways.

[0101] A specific implementation example is given below. It should be noted that the following is only an example and is not intended to be limiting.

[0102] Figure 4 A schematic diagram of a charging control method provided in an embodiment of the present disclosure Figure 3 See also Figure 4 , step 123 in the charging control method provided in the embodiment of the present disclosure may include the following steps:

[0103] Step 124: determining a target mapping relationship corresponding to the rated charging parameter based on the rated charging parameter of the wireless charging device and a mapping relationship between different preset signal strength mapping values ​​and charging parameters corresponding to different preset rated charging parameters;

[0104] Step 125: Based on the target mapping relationship, the charging parameter corresponding to the current signal strength mapping value is used as the target charging parameter.

[0105] In step 124, the preset rated charging parameters may include different preset rated powers, different preset rated charging voltages or different preset rated charging currents of the wireless charging device; for example, the preset rated powers of the wireless charging device may include 50W, 30W, 20W, etc.; or, the preset rated charging voltages of the wireless charging device may include 20V, 15V, 10V, etc.; or, the preset rated charging currents of the wireless charging device may include 5A, 3A, 2.5A, etc.

[0106] The target mapping relationship may be a mapping relationship between a preset signal strength mapping value and a charging parameter determined based on the rated charging parameters of the wireless charging device, wherein different preset rated charging parameters correspond to different mapping relationships between preset signal strength mapping values ​​and charging parameters.

[0107] It can be understood that when the above-mentioned charging parameter is power, the above-mentioned target mapping relationship can be used to characterize the mapping relationship between the above-mentioned preset signal strength mapping value and power; when the above-mentioned charging parameter is charging voltage, the above-mentioned target mapping relationship can be used to characterize the mapping relationship between the above-mentioned preset signal strength mapping value and charging voltage; when the above-mentioned charging parameter is charging current, the above-mentioned target mapping relationship can be used to characterize the mapping relationship between the above-mentioned preset signal strength mapping value and charging current; and so on.

[0108] In the disclosed embodiment, the rated charging parameters of the wireless charging device can be used to find a target mapping relationship corresponding to the rated charging parameters from the mapping relationships between different preset signal strength mapping values ​​and charging parameters corresponding to different preset rated charging parameters, thereby expanding the range of wireless charging devices with different rated charging parameters that can be selected by the terminal device, improving the adaptability of the terminal device to different wireless charging devices, making the target charging parameters of the wireless charging device determined subsequently more accurate, and improving the charging efficiency of the wireless charging device for the terminal device.

[0109] Exemplarily, the preset rated charging parameter of the wireless charging device is a preset rated power, and the mapping relationship can be a mapping relationship between a preset signal strength mapping value and a charging power. The mapping relationship between different preset signal strength mapping values ​​and charging parameters corresponding to different preset rated charging parameters can be shown in Table 1; wherein, mapping relationship 1 in Table 1 can be shown in Table 2; and mapping relationship 2 in Table 1 can be shown in Table 3.

[0114] Table 3

[0115] Preset signal strength mapping value (mV) 5000 4000 3500 Charging power (W) 20 10 10

[0116] In step 125, a charging parameter corresponding to the current signal strength mapping value may be determined from the target mapping relationship between the preset signal strength mapping value and the charging parameter, and the charging parameter may be used as the target charging parameter.

[0117] For example, when the current signal strength mapping value is 4500 millivolts (mV), the first signal strength threshold value is 5000mV and the rated power of the wireless charging device is 50W, it is determined that the target power of the wireless charging device can be 30W; at this time, the target mapping relationship can be used to characterize the mapping relationship between the current signal strength mapping value of 4500mV and the target power of 30W, and the target charging parameter can be the target power of 30W.

[0118] The charging control method provided by the embodiment of the present disclosure can determine the target mapping relationship corresponding to the rated charging parameters through the rated charging parameters of the wireless charging device and the mapping relationship between different preset signal strength mapping values ​​and charging parameters corresponding to different preset rated charging parameters when the signal strength mapping value is less than or equal to the first signal strength threshold value, and then determine the target charging parameters through the current signal strength mapping value and the target mapping relationship, so that when a misalignment occurs between the terminal device and the wireless charging device, the target charging parameters can be adjusted to improve the charging efficiency of the wireless charging device for the terminal device and reduce the heat generated by the terminal device during the charging process.

[0119] Figure 5 A schematic diagram of a charging control method provided in an embodiment of the present disclosure Figure 4 See also Figure 5 , step 123 in the charging control method provided in the embodiment of the present disclosure may include the following steps:

[0120] Step 126: When the current signal strength mapping value is less than or equal to the first signal strength threshold value and greater than the second signal strength threshold value, use a first preset charging parameter corresponding to the current signal strength mapping value as the target charging parameter;

[0121] Step 127: When the current signal strength mapping value is less than or equal to the second signal strength threshold value and greater than the third signal strength threshold value, use the second preset charging parameter corresponding to the current signal strength mapping value as the target charging parameter;

[0122] Step 128: When the current signal strength mapping value is less than or equal to the third signal strength threshold value, use the third preset charging parameter corresponding to the current signal strength mapping value as the target charging parameter.

[0123] In the disclosed embodiment, the first signal strength threshold value, the second signal strength threshold value and the third signal strength threshold value decrease successively, and the offset distances between the terminal device and the wireless charging device respectively corresponding to the first signal strength threshold value, the second signal strength threshold value and the third signal strength threshold value are all within the range of 5 mm to 10 mm.

[0124] Here, the sizes of the first preset charging parameter, the second preset charging parameter and the third preset charging parameter decrease successively as the first signal strength threshold value, the second signal strength threshold value and the third signal strength threshold value decrease successively, and the first preset charging parameter, the second preset charging parameter and the third preset charging parameter are all smaller than the rated charging parameter.

In step 128, using the third preset charging parameter corresponding to the current signal strength mapping value as the target charging parameter may include: based on the current signal strength mapping value, determining the third preset charging parameter from the target mapping relationship corresponding to the rated charging parameter of the wireless charging device, and using the third preset charging parameter as the target charging parameter of the wireless charging device.

[0128] In another embodiment, the rated charging parameter, i.e., the rated power, of the wireless charging device may also be 30W. According to a large number of sample experiments, only the first signal strength threshold value is predetermined to be 5000mV and the second signal strength threshold value is predetermined to be 4000mV; and the first preset charging parameter, i.e., the first preset power, corresponding to the first signal strength threshold value is 20W, and the second preset charging parameter, i.e., the second preset power, corresponding to the second signal strength threshold value is 10W; at this time, if the current signal strength mapping value is 4500mV, it falls within the preset signal strength mapping value range of 4000 to 5000mV, that is, the target charging parameter, i.e., the target power, is determined to be 20W.

[0129] In addition, in one embodiment, if the current signal strength mapping value is 5500mV, that is, greater than the first signal strength threshold value of 5000mV, the rated power of the wireless charging device can be used as the target power. For example, when the rated power of the wireless charging device is 50W, the target power corresponding to the current signal strength mapping value is 50W; when the rated power of the wireless charging device is 30W, the target power corresponding to the current signal strength mapping value is 30W.
