[0033] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0040] Figure 6 is a block diagram illustrating an electronic device according to an exemplary embodiment of the present disclosure. Detailed Implementation

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0042] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0043] In related wireless charging methods, the power loss (Ploss) parameter configuration of the charging receiver (Rx) has only one set of parameters. This set of parameters must ensure that the charging transmitter (TX) and the charging receiver can work stably in various positional relationships, while not triggering foreign object detection (FOD) protection to disconnect the charging. Therefore, the power loss threshold in the power loss parameter will have a large margin in each power range, such as 5% of the output power of the charging receiver. Although this can ensure the stable operation of the wireless charging process, it is also detrimental to the detection of foreign objects.

[0044] In view of this, embodiments of the present disclosure provide a wireless charging method, apparatus, device, medium, computer program product, and computer program. By adapting the corresponding power loss parameters according to the location voltage, the use of a uniform margin for the power loss parameters is avoided. This ensures the stability of the wireless charging process and improves the foreign object detection capability when managing the wireless charging process based on the power loss parameters, thereby enhancing the safety of wireless charging.

[0045] It should be noted that, for ease of description, the following embodiments all use an electronic device as the wireless charging receiver as an example. When the electronic device is the wireless charging transmitter, some or all of the data required in executing the wireless charging method can be obtained by communicating with the wireless charging receiver.

[0046] Figure 1 is a flowchart illustrating a wireless charging method according to an exemplary embodiment. This wireless charging method can be used as a wireless charging receiver, such as an electronic device with wireless charging functionality, like a mobile phone, tablet computer, or smart wearable device. Furthermore, this wireless charging method can also be used as a wireless charging transmitter, such as a wireless charger. As shown in Figure 1, the wireless charging method includes the following steps: S110-S120.

[0047] S110, acquire the voltage at the target location received by the wireless charging receiver.

[0048] The location voltage can be understood as the voltage corresponding to the first loop of the AC-to-DC circuit in the wireless charging receiver.

[0049] In this embodiment of the disclosure, when the wireless charging receiver is placed on the wireless charging transmitter, the wireless charging receiver can perform position voltage measurement, thereby obtaining the position voltage at this moment, i.e., the target position voltage.

[0050] S120 determines the target power loss parameter corresponding to the target location voltage based on the correlation between the location voltage and the power loss parameter. The target power loss parameter is used to manage the wireless charging process.

[0051] In this embodiment of the disclosure, the correlation between location voltage and power loss parameters can be pre-stored in the electronic device. In this way, after obtaining the target location voltage received by the wireless charging receiver, the target power loss parameter corresponding to the target location voltage can be determined according to the pre-stored correlation between location voltage and power loss parameters.

[0052] In some implementations, after obtaining the target power loss parameters, the wireless charging process can be managed based on these parameters. In some implementations, managing the wireless charging process based on the target power loss parameters may include foreign object detection during the wireless charging process.

[0053] By using the above method, the target location voltage received by the wireless charging receiver is obtained, and then the corresponding target power loss parameter is adapted to the target location voltage according to the correlation between the location voltage and the power loss parameter. This avoids using a uniform margin for the power loss parameter and allows the target power loss parameter to be set specifically according to the actual location voltage. This ensures the stability of the wireless charging process and improves the foreign object detection capability when managing the wireless charging process based on the power loss parameter, thereby improving the safety of wireless charging.

[0054] In some implementations, the method of this disclosure may further include the following steps:

[0055] Obtain the position voltage corresponding to the wireless receiver being located at a preset position of the wireless charging transmitter, and the minimum power loss threshold that makes the wireless charging process stable under the position voltage.

[0056] The correlation is obtained based on the position voltage corresponding to different preset positions of the wireless receiver and the corresponding minimum power loss threshold.

[0057] In this embodiment, the wireless charging receiver can be placed at different positions on the wireless charging transmitter to measure the corresponding position voltage at each position. Simultaneously, the minimum power loss threshold that ensures stable wireless charging at each position is measured. Then, a correlation can be established based on the position voltage corresponding to the wireless receiver at different preset positions on the wireless transmitter and the corresponding minimum power loss threshold.

[0058] As an example, as shown in Figure 2, taking a vertical wireless charger as an example, when the mobile phone is placed on the wireless charger, Z=0mm and Y=0mm can be preset first. Then, the X-axis can be moved. Taking the maximum offset distance N between the mobile phone and the wireless charger as the reference line, the position voltages are defined as follows: S0 when the mobile phone is at zero offset (0 mm), S1 when the mobile phone is at half offset (N / 2 mm), and S2 when the mobile phone is at maximum offset (N mm). By averaging multiple samples tested in the laboratory, the values ​​of S0, S1, and S2 are stored in the mobile phone for later retrieval.

[0059] In addition, three sets of minimum power loss thresholds were tested and pre-stored for three cases: zero offset, half offset, and extreme offset. Then, the position voltage measured at zero offset was correlated with the minimum power loss threshold, the position voltage measured at half offset was correlated with the minimum power loss threshold, and the position voltage measured at extreme offset was correlated with the minimum power loss threshold, thus obtaining the correlation between position voltage and power loss parameters.

[0060] In some implementations, in order to reduce the number of measurements, after obtaining the position voltage at different locations, multiple voltage intervals can be obtained based on the position voltage, and the voltage intervals can be associated with the corresponding minimum power loss threshold to obtain the correlation between position voltage and power loss parameters.

[0061] As an example, after obtaining the position voltages corresponding to zero offset, half offset, and extreme offset, multiple voltage intervals can be obtained based on the position voltages corresponding to zero offset, half offset, and extreme offset. For example, the intervals can be divided into three intervals: greater than or equal to S0, greater than or equal to S1 and less than S0, and greater than or equal to S2 and less than S1. Thus, the interval with position voltage greater than or equal to S0 can be associated with the minimum power loss threshold corresponding to zero offset, the interval with position voltage greater than or equal to S1 and less than S0 can be associated with the minimum power loss threshold corresponding to half offset, and the interval with position voltage greater than or equal to S2 and less than S1 can be associated with the minimum power loss threshold corresponding to extreme offset, thereby obtaining the correlation between position voltage and power loss parameters.

[0062] In some implementations, the power loss parameters may include, in addition to the minimum power loss threshold, parameters such as the power transmission loss of the wireless charging transmitter and the power transmission loss of the wireless charging receiver.

[0063] In this disclosure, the acquisition of the target location voltage received by the wireless charging receiver can take several different forms. In some embodiments, the target location voltage can be acquired before wireless charging begins to further determine the target power loss parameters and manage the upcoming wireless charging process. In other embodiments, the target location voltage can be acquired during wireless charging to further determine the target power loss parameters and manage the ongoing wireless charging process. These will be described in detail below with reference to specific embodiments.

[0064] In some implementations, obtaining the target location voltage received by the wireless charging receiver may include the following steps:

[0065] During the wireless charging authentication process between the wireless charging receiver and the wireless charging transmitter, the voltage at the target location received by the wireless charging receiver is obtained.

[0066] In this embodiment of the disclosure, after the wireless charging receiver is placed on the wireless charging transmitter, the wireless charging receiver can perform charging authentication with the wireless charging transmitter. The charging authentication can be considered as the authentication process before formally starting wireless charging. During the charging authentication process, the voltage at the target location received by the wireless charging receiver can be obtained so that the target power loss parameters for managing the wireless charging process can be obtained in a targeted manner, thereby improving the foreign object detection capability while ensuring the stability of the wireless charging process.

[0067] In some implementations, charging authentication may include processes such as signal strength packet exchange, identity packet exchange, configuration packet exchange, foreign object detection status packet exchange, handshake packet identification exchange, and private authentication exchange. This disclosure does not specifically limit the charging authentication process.

[0068] In some implementations, obtaining the target location voltage received by the wireless charging receiver may include the following steps:

[0069] In response to confirming a successful communication connection between the wireless charging receiver and the wireless charging transmitter, the voltage at the target location received by the wireless charging receiver is acquired.

[0070] In this embodiment of the disclosure, after the wireless charging receiver and the wireless charging transmitter have successfully established a communication connection, the voltage at the target location received by the wireless charging receiver can be obtained.

[0071] In some implementations, the successful communication connection between the wireless charging receiver and the wireless charging transmitter can be determined after the completion of O1 packet (i.e., signal strength data packet) exchange. That is, in some implementations, the target location voltage received by the wireless charging receiver can be obtained in response to the confirmation that the wireless charging receiver and the wireless charging transmitter have completed O1 packet confirmation.

[0072] In some implementations, the wireless charging process can be managed based on target power loss parameters after the private authentication interaction is completed, in order to perform wireless power transmission.

[0073] It is understood that the aforementioned embodiments are processes for determining the target power loss parameters before wireless charging begins, in order to select suitable target power loss parameters. In some implementations, considering that after the target power loss parameters have been determined and wireless charging is performed based on the target power loss parameters, there is a possibility that the relative displacement between the wireless charging receiver and the wireless charging transmitter may occur during the wireless charging process, which may lead to changes in system gain and the coupling efficiency (CEP) not returning to zero. In this case, the previously determined target power loss parameters may no longer be applicable to the charging scenario after the current displacement.

[0074] In response to the above scenario, this embodiment of the disclosure proposes that, during the wireless charging process, under certain conditions, the voltage at the target location received by the wireless charging receiver can also be obtained.

[0075] Therefore, in some implementations, obtaining the target location voltage received by the wireless charging receiver may include the following steps:

[0076] During wireless charging, in response to determining that the coupling efficiency deviates from the preset efficiency value, the voltage at the target location received by the wireless charging receiver is acquired.

[0077] In this embodiment of the disclosure, if the coupling efficiency deviates from the preset efficiency value, it can also be understood as the coupling efficiency not being able to return to zero. In this case, it means that the wireless charging receiver cannot charge with a better energy transmission efficiency. Therefore, during the wireless charging process, if the coupling efficiency deviates from the preset efficiency value, the voltage at the target location received by the wireless charging receiver can be re-acquired to re-adapt the corresponding target power loss parameters so that the coupling efficiency matches the preset efficiency value, and the wireless charging receiver can charge with a better energy transmission efficiency again.

[0078] Furthermore, considering that in some cases, the coupling efficiency parameter can be adjusted to match the preset efficiency value, therefore, in some embodiments, in response to determining that the coupling efficiency deviates from the preset efficiency value, obtaining the target location voltage received by the wireless charging receiver may include the following steps:

[0079] In response to the determination that the coupling efficiency deviates from the preset efficiency value, the coupling efficiency parameter is adjusted at least once to obtain the adjusted coupling efficiency.

[0080] When the adjusted coupling efficiency deviates from the preset efficiency value, the voltage at the target location received by the wireless charging receiver is obtained.

[0081] In this embodiment of the disclosure, if the coupling efficiency deviates from the preset efficiency value, the coupling efficiency parameter can be adjusted first, and it can be observed whether the coupling efficiency can be matched with the preset efficiency value by adjusting the coupling efficiency parameter. If the coupling efficiency can be matched with the preset efficiency value, then the target power loss parameter does not need to be adjusted, so as to reduce the workload of adjustment.

[0082] If the coupling efficiency still deviates from the preset efficiency value after adjusting the coupling efficiency parameter, it means that the method of adjusting the coupling efficiency parameter cannot recharge with a better energy transmission efficiency. In this case, the target location voltage received by the wireless charging receiver can be obtained. Then, based on the correlation between the location voltage and the power loss parameter, the target power loss parameter corresponding to the target location voltage can be determined. Furthermore, the wireless charging process can be managed based on the target power loss parameter so that the coupling efficiency matches the preset efficiency value.

[0083] In some implementations, the coupling efficiency parameter can be adjusted three times, and it can be determined whether the coupling efficiency obtained after the three adjustments deviates from the preset efficiency value.

[0084] In some implementations, obtaining the target location voltage received by the wireless charging receiver when the adjusted coupling efficiency deviates from a preset efficiency value may include the following steps:

[0085] If the adjusted coupling efficiency deviates from the preset efficiency value, the wireless charging receiver is controlled to shut down the load channel, and the wireless charging transmitter is controlled to be in the initial charging state.

[0086] The target location voltage received by the wireless charging receiver is obtained when the load channel of the wireless charging receiver is in a closed state and the wireless charging transmitter is in the initial charging state.

[0087] One method involves controlling the wireless charging receiver to shut down its load channel, for example, by setting the ICL (Current Limit) to 0. By controlling the wireless charging receiver to shut down its load channel, charging can be prevented from continuing, thus facilitating accurate acquisition of the voltage at the target location.

[0088] Controlling the wireless charging transmitter to be in the initial charging state can include controlling the wireless charging transmitter to be at an initial voltage and initial frequency. The initial voltage and initial frequency refer to the default voltage and default frequency configured for the wireless charging transmitter before charging begins, respectively. This can also be understood as the voltage and frequency configured for the wireless charging transmitter when detecting location voltage.

[0089] By controlling the wireless charging transmitter to be in the initial charging state, the voltage and frequency can be unified with those before charging begins, thereby unifying the standard for obtaining the voltage at the target location, so as to accurately obtain the target power loss parameters.

[0090] The following describes the execution process of the wireless charging method according to an embodiment of the present disclosure with reference to the flowcharts of the wireless charging method shown in Figures 3 and 4, using a complete example.

[0091] As shown in Figure 3, after placing the phone on the wireless charger, the phone and wireless charger first exchange signal strength data packets. After the signal strength data packet exchange is completed, the phone and wireless charger successfully establish a communication connection. At this point, the wireless charger is in the initial charging state. The phone can then detect the received location voltage to obtain the target location voltage. Subsequently, the phone can interact with the wireless charger through identity data packet exchange, configuration packet exchange, foreign object detection status data packet exchange, handshake packet recognition exchange, and private authentication exchange. After completing the private authentication exchange, the phone can find the target power loss parameter corresponding to the target location voltage from the pre-stored association relationships. The phone can then begin wireless charging and manage the wireless charging process based on the target power loss parameter. For example, the target power loss parameter can be used to detect whether there is a foreign object between the phone and the wireless charger.

[0092] As shown in Figure 4, during the wireless charging process, if the phone and the wireless charger become misaligned at a certain moment, causing a change in system gain and preventing the coupling efficiency from returning to zero, the coupling efficiency parameter is first adjusted to return it to zero. If the coupling efficiency parameter cannot be adjusted to zero after more than three consecutive adjustments, the charging current limit in the phone is set to 0, the wireless charger is set to the initial charging state, the target position voltage received by the wireless charging receiver is acquired again, and then the target power loss parameter corresponding to the target position voltage is re-determined based on the correlation between the position voltage and the power loss parameter, and the wireless charging process is restarted.
