Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of wireless power supply technology, and in particular to a wireless power supply method, device, computer equipment and storage medium. Background Art
[0002] Wireless power transfers energy via radio waves or magnetic fields, enabling load devices to obtain power from power supply devices without direct physical contact.
[0003] If there is a foreign object between the power supply device and the load device or the coil is out of position, the received power will decrease, causing the wireless power supply to slow down or even disconnect. In actual application, the coil position and appearance design of each power supply device and load device may be different, resulting in the user being unable to determine the best relative position of the load device and the power supply device when placing the load device on the power supply device; at the same time, the user may also equip the power supply device or the load device with a mobile phone case or other decorations according to their own preferences, which will further affect the recognizability of the coil position of the power supply device and the load device; in addition, these factors may not have the same effect on the power loss during the wireless power supply process at different positions, and thus the position where the coils are fully aligned may not necessarily be the best power supply position (i.e. the position with the least power loss), making it more difficult for users to determine the best relative position of the load device and the power supply device.
[0004] In related technologies, placement is usually based solely on user intuition, and users lack a sense of purpose. At the same time, since users cannot know whether the current placement position is the best power supply position, users often place the load device in a poor position for wireless power supply, resulting in low power supply and high power loss.

[0090] The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects:
[0091] In the embodiments of the present disclosure, a power supply device receives non-conductive losses sent by a load device at at least one position.

[0108] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0109] The terms used in the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the present disclosure. The singular forms "a", "the", and "said" used in the present disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more of the associated listed items.
[0110] It should be understood that although the terms first, second, third, etc. may be used in the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".
[0111] Wireless power transfers energy via radio waves or magnetic fields, enabling load devices to obtain power from power supply devices without direct physical contact.
[0112] If there is a foreign object between the power supply device and the load device or the coil is out of position, the received power will decrease, causing the wireless power supply to slow down or even disconnect. For example, see Figure 1 , the coil position deviation is small in the left placement method, which is strong coupling, and the coil position deviation is large in the right placement method, which is weak coupling. In actual application, the coil position and appearance design of each power supply device and load device may be different, resulting in the user being unable to determine the best relative position of the load device and the power supply device when placing the load device on the power supply device; at the same time, the user may also equip the power supply device or the load device with a mobile phone case or other decorations according to their own preferences, which will further affect the recognizability of the coil position of the power supply device and the load device; in addition, these factors may not have the same effect on the power loss in the wireless power supply process at different positions, and thus the position where the coils are fully aligned is not necessarily the best power supply position (i.e., the position with the least power loss), making it more difficult for users to determine the best relative position of the load device and the power supply device.
[0113] In related technologies, placement is usually based solely on user intuition, and users lack a sense of purpose. At the same time, since users cannot know whether the current placement position is the best power supply position, users often place the load device in a poor position for wireless power supply, resulting in low power supply and high power loss. This is reflected in the user experience, resulting in slow charging, high heat, and poor user experience.
[0114] In view of this, the present disclosure provides a wireless power supply method, apparatus, computer equipment and storage medium.
[0115] For ease of description, an exemplary application scenario is provided below. Figure 2, where L1 is the transmitting coil on the side of the power supply device (such as a wireless charging base, a mobile phone or a tablet computer supporting the wireless reverse charging function), and L2 is the receiving coil on the side of the load device (such as a mobile phone supporting the wireless charging function, a wireless earphone, etc.). Electric energy is transmitted between L1 and L2 through alternating current. After receiving the alternating current, L2 converts the alternating current into direct current through a DC / AC conversion module, and provides stable direct current to the battery (load) through an LDO (Low-dropout Regulator). In an exemplary control logic, the power supply device and the load device perform wireless charging based on a preset charging protocol, and the power supply process includes the following steps:
[0116] S201, the power supply device sends a broadcast to detect the load devices around the power supply device;
[0117] S202, in response to receiving the broadcast sent by the power supply device, the load device returns the received signal strength value to the power supply device;
[0118] S203, in response to receiving the signal strength value sent by the load device, the power supply device sends configuration information to the load device, including identification information, charging parameters, etc.;
[0119] At this point, the power supply device and the load device complete the handshake. However, the process of the user placing the load device on the power supply device is a process from far to near. When the handshake is completed, this process from far to near usually has not ended. Therefore, the load device can also perform the following steps:
[0120] S204, in response to the DC voltage converted by the DC / AC conversion module being greater than or equal to the voltage threshold, turn on the LDO, so that the direct current converted by the DC / AC conversion module is regulated by the LDO and then supplies power to the battery module.
[0121] It should be understood that the wireless charging scenario is a common scenario of the wireless power supply technology. Therefore, this disclosure may use terms such as "wireless charging" and "charging" to exemplarily illustrate the wireless power supply control method provided by this disclosure. However, these terms and the above exemplary application scenarios cannot limit the application scope of this disclosure. For example, a load device without a charging function or even without a battery module does not affect the realization of the original technical effects of the wireless power supply control method provided by this disclosure. In addition, according to different actual settings, "greater than or equal to" used in this disclosure can also be "greater than", "less than or equal to" can also be "less than", or, according to the different meanings of the threshold, the judgment conditions of the method provided by this disclosure can also be adaptively reversed. This disclosure does not make any restrictions on this.
[0122] Next, the embodiments of this disclosure will be described in detail.
[0123] In a first aspect, a wireless power supply method applied to the power supply device side is provided. Please refer to Figure 3 , Figure 3 which is a flowchart of a wireless power supply method shown in some embodiments of the present disclosure, and includes the following steps:
[0124] Step S301, receiving the non-conductive loss sent by the load device at at least one position, where the non-conductive loss is determined by the load device according to the induced voltage collected when the induced voltage is greater than or equal to the voltage threshold, and the non-conductive loss is used to characterize the loss generated between the load device and the power supply device due to non-conductive factors, and the non-conductive factors include position offset.
[0125] Taking Figure 2 the application scenario shown as an example, the induced voltage of the load device can be the alternating current voltage induced at L2 or the direct current voltage at the conversion point of the AC / DC conversion module. During the process that the user brings the load device close to the power supply device and keeps the relative positions of the two stable, the power supply device can first complete handshake communication with the load device and then supply power to the load device at a preset voltage; on the load device side, an increasingly large and stable voltage will be induced. Therefore, in the above step, the non-conductive loss needs to be determined according to the induced voltage collected when the induced voltage is greater than or equal to the voltage threshold, so as to ensure that the user has placed the load device in a position where wireless charging can be performed, thereby minimizing the accumulation of invalid data, improving the execution efficiency of the method and reducing the resource occupancy of the method. It should be noted that since the process that the user brings the load device close to the power supply device and keeps the relative positions of the two stable usually only takes a short time, and there is a certain time interval for each polling of the induced voltage by the load device, the induced voltage obtained by each polling of the induced voltage by the load device is often multiple discrete points with jumps. Therefore, the first collected induced voltage greater than or equal to the voltage threshold is not necessarily equal to the voltage threshold itself, and when the induced voltage is greater than or equal to the voltage threshold, the relative positions between the load device and the power supply device usually have been kept stable.
[0126] The meaning of non-conductive factors is factors other than conductors that may affect the power transmission between the power supply device and the load device (for example, causing power loss between the power supply device and the load device), such as the planar or three-dimensional position offset between the receiving coil of the load device and the transmitting coil of the power supply device, the damage and aging of the receiving coil of the load device and the transmitting coil of the power supply device, non-conductive foreign objects between the load device and the power supply device (such as assembled mobile phone cases, surface wear and dirt of the device), etc.
[0127] Before the induced voltage is greater than or equal to the voltage threshold, the power supply device and the load device are still in the detection stage (or power supply preparation stage). There is actually no high-power power transmission between them. At this time, the influence of power loss is mainly affected by non-conductor factors. For example, position offset will affect the power loss when the power supply device and the load device are still in the detection stage. In summary, the present disclosure realizes the detection of power loss caused by non-conductor factors at the current placement position by determining non-conductor loss according to the induced voltage collected by the load device when the induced voltage is greater than or equal to the voltage threshold. Once the load device starts to supply power to the load, it may cause a voltage drop or other influences at the AC / DC conversion module due to the power consumption of the load and the changes in voltage and current by the power supply control module related to the load. Therefore, if the charging logic of the load device is to start supplying power to the load in response to the voltage reaching voltage threshold A, preferably, the voltage threshold (hereinafter referred to as voltage threshold B) described in step S301 can be made less than voltage threshold A, and the non-conductor loss can be determined according to a certain voltage value (including endpoints) between voltage threshold B and the first induced voltage that satisfies voltage threshold A; or, voltage threshold A = voltage threshold B, and the non-conductor loss can be determined according to the first induced voltage that satisfies voltage threshold A and voltage threshold B (that is, the non-conductor loss is determined by the load device according to the induced voltage collected when the induced voltage is first greater than or equal to the voltage threshold). If the charging logic of the load device is to determine whether the current charging process is a calibration process (which can be judged by configuring the corresponding protocol and enabling the load device to judge through notification interaction with the power supply device or according to the user's instruction), and if the current charging process is a calibration process, it will keep not supplying power to the load, then preferably, the non-conductor loss can be determined according to the induced voltage value when the induced voltage is greater than or equal to voltage threshold B and the change within a preset time is less than or equal to the change amount threshold, so as to ensure that the relative position between the load device and the power supply device has been stable as much as possible and improve the accuracy of the method.
[0128] Step S302: According to the non-conductor loss sent by the load device at at least one position, determine the wireless power supply position among the at least one position, and generate a prompt message carrying the wireless power supply position, where the prompt message is used to prompt the user to place the load device at the wireless power supply position for wireless power supply.
[0129] Preferably, determining the wireless power supply position among the at least one position according to the non-conductive loss transmitted by the load device at at least one position includes determining the position corresponding to the minimum non-conductive loss among the non-conductive losses transmitted by the load device at at least one position as the wireless power supply position, so that the expected power supply effect of the wireless power supply position can reach the optimal. In addition, a preset threshold can also be set, and the position corresponding to the non-conductive loss less than the preset threshold is determined as the wireless power supply position. It should be understood that the above-mentioned "minimum" is only an exemplary illustration, and it can also be understood as "relatively small", that is, considering various factors (such as presenting the non-conductive loss to the user and receiving the user's instructions to determine the user influence factors), among the non-conductive losses transmitted at at least one position, the position corresponding to the relatively small non-conductive loss is determined as the wireless power supply position. According to different actual applications, the finally determined wireless power supply position may also be the position corresponding to the "second smallest" or "non-largest" non-conductive loss.
[0130] Among them, the specific way to prompt the user to place the load device at the wireless power supply position for wireless power supply can be in the form of visual display (that is, displaying the position on the device screen), which is more intuitive and convenient to operate; it can also be in the form of audio broadcast, converting the relevant information of the wireless power supply position into audio and broadcasting it to the user. The application scenario is wider, and it can also prompt the wireless charging position to the user when the user is not looking at the load device, and it is more friendly to visually impaired people.
[0131] In the embodiment of the present disclosure, the power supply device receives the non-conductive loss transmitted by the load device at at least one position. The non-conductive loss is determined by the load device according to the induced voltage collected when the induced voltage is greater than or equal to the voltage threshold, and determines the wireless power supply position among the at least one position according to the non-conductive loss transmitted by the load device at at least one position; next, generates a prompt message carrying the wireless power supply position, and the prompt message is used to prompt the user to place the load device at the wireless power supply position for wireless power supply. Since the non-conductive loss includes the loss generated between the load device and the power supply device due to non-conductive factors such as position offset, the method provided by the present disclosure can determine the wireless power supply position according to the magnitude of the non-conductive loss among at least one position and prompt this position to the user, so that the user has a more targeted sense during the wireless power supply process and can find the optimal wireless power supply position, effectively reducing the impact of non-conductive factors such as position offset on wireless power supply, thereby improving the charging power and the user experience during the wireless power supply process.
[0132] In some embodiments of the present disclosure, exemplary ways of generating prompt information carrying the wireless power supply position are also provided, such as the following three alternative generation methods:
[0133] Generation method 1: The method further includes:
[0134] Recording the order in which the load device transmits non-conductive losses at the at least one position;
[0135] The generation of the prompt information carrying the wireless power supply position includes:
[0136] Generating the prompt information carrying the wireless power supply position according to the order in which the load device transmits non-conductive losses at the wireless power supply position.
[0137] For example, the user places the load device at three positions respectively. Among them, the non-conductive loss at the position of the second placement is the smallest among the non-conductive losses at all positions. Then, prompt information including "the position of the second placement is the optimal wireless power supply position" can be generated. Specifically, the recording method can be to record the placement order each time (that is, which non-conductive loss is obtained at which placement), or when the non-conductive loss at the current position is less than (or equal to) the smallest non-conductive loss among each position placed before (or the user has not placed the load device at any position before), refreshing the order of this placement to a register or variable, and generating prompt information according to the order stored in the register or variable.
[0138] The above method generates prompt information by recording the placement order, with low resource consumption, simple implementation method, and strong versatility.
[0139] Generation method 2: The method further includes:
[0140] Presenting a placement guide message, the placement guide message including at least one preset position, and the placement guide message being used to guide the user to place the load device at the at least one preset position in a preset order;
[0141] The generation of the prompt information carrying the wireless power supply position includes:
[0142] Generating the prompt information carrying the wireless power supply position according to the preset position corresponding to the wireless power supply position among the at least one preset position.
[0143] Specifically, please refer to Figure 4, the mobile phone (power supply device) presents a placement guidance message to the user in the form of a visual pop-up window. Among them, the placement guidance message includes five preset positions (please refer to the dotted boxes in the figure), and the numbers in the boxes are the order of placement; the user can, according to the visual message, place the load device on preset position 1 to preset position 5 in sequence (the user can also interrupt the placement process midway and directly determine the wireless power supply position according to the positions that have been placed). After the placement is completed, the mobile phone judges the preset position corresponding to the smallest non-conductive loss among preset position 1 to preset position 5. For example, if the non-conductive loss received by the mobile phone during the user's first placement process is the smallest non-conductive loss among all placement positions, the prompt information can be generated according to preset position 1. For example, please refer to Figure 5 , the prompt information highlights preset position 1 (i.e., the shaded part in the figure) to prompt the user to place the load device on preset position 1 for wireless power supply.
[0144] The above optional method provides a more friendly interaction method, making it easier for the user to identify the target position and having a good user experience.
[0145] Generation method 3: The method further includes:
[0146] Position the load device at at least one position, and determine the wireless power supply position according to the position offset between the load device and the power supply device, and generate prompt information carrying the wireless power supply position.
[0147] Among them, the positioning method can be based on an auxiliary coil (that is, positioning the load device coil according to the non-conductive loss difference between the load device coil and multiple coils on the power supply device), or it can be based on a pressure sensing module (that is, positioning the load device according to the pressure sensing information collected by the pressure sensor at each position of the power supply device). After the positioning is completed, the best wireless power supply position can be determined based on the difference between the preset position of the power supply device coil and the current position of the load device, and prompt information can be generated (such as prompting the user to move the load device in a certain direction, or displaying the wireless power supply position matching the load device to the user), so as to more intuitively guide the user to perform wireless power supply at the wireless power supply position.
[0148] In some embodiments of the present disclosure, please refer to Figure 6 , the method further includes:
[0149] Step S601, record the wireless power supply position and the device identifier corresponding to the load device;
[0150] Step S602, in response to the device identifier corresponding to the load device having been recorded, set the wireless power supply position corresponding to the device identifier as the wireless power supply position.
[0151] That is, if the load device has been calibrated for the wireless power supply position, the recorded wireless power supply position can be directly determined as the wireless power supply position for this power supply. Thus, after calibration is completed, it is not necessary to calibrate the wireless power supply position of the load device again, which improves the execution speed of the method and reduces the operation cost of the method.
[0152] In some embodiments of the present disclosure, refer to Figure 7 , the method further includes:
[0153] Step S701, record the non-conductive loss corresponding to the wireless power supply position and the device identifier corresponding to the load device;
[0154] Step S702, in response to the device identifier corresponding to the load device having been recorded and the non-conductive loss sent by the load device at the current position being less than or equal to the non-conductive loss corresponding to the device identifier, determine the current position of the load device as the wireless power supply position;
[0155] And / or, in response to the device identifier corresponding to the load device having been recorded and the non-conductive loss sent by the load device at the current position being less than or equal to the non-conductive loss corresponding to the device identifier, send a notification to the load device so that the load device starts to supply power to the load.
[0156] In other words, when the wireless power supply position corresponding to the load device is determined, the non-conductive loss value corresponding to the wireless power supply position can be recorded, and in the subsequent process, in response to the device identifier corresponding to the load device having been recorded, when the non-conductive loss sent by the load device at the current position is less than or equal to the previously recorded non-conductive loss value, the current position can be directly determined as the wireless power supply position or a notification can be directly sent to the load device so that the load device directly supplies power to the load. In addition, the method can also refresh the non-conductive loss value determined in the above process and smaller than the previously recorded non-conductive loss value to the non-conductive loss record corresponding to the load device, so that in the next charging process of the load device, the smallest non-conductive loss is used as the threshold for judgment.
[0157] The above embodiments give the subsequent charging process after the load device has been calibrated for the wireless power supply position. In response to the current position being good (i.e., the non-conductive loss is less than the previously recorded value), the current position is directly prompted to the user or charging is directly started, thus realizing the complete process of calibration - application, enabling each load device to determine the corresponding non-conductive loss threshold after at least one calibration, so that each load device can perform wireless charging at the position most suitable for the power supply device and its own characteristics, improving the wireless charging power and maximizing the user experience.
[0158] In a second aspect, a wireless power supply method applied to the load device side is provided. Please refer to Figure 8 , which includes:
[0159] Step S801: Determine the non-conductor loss according to the voltage collected when the sensed voltage is greater than or equal to the voltage threshold, where the non-conductor loss is used to characterize the loss generated between the load device and the power supply device due to non-conductor factors, and the non-conductor factors include position offset.
[0160] Taking Figure 2 the shown application scenario as an example, the induced voltage of the load device can be the alternating current voltage sensed at L2 or the direct current voltage at the conversion point of the AC / DC conversion module. It should be noted that since the process of the user bringing the load device close to the power supply device and keeping their relative positions stable usually only takes a short time, and there is a certain time interval for each polling of the induced voltage by the load device, the induced voltage obtained by each polling of the load device for the induced voltage is often multiple discrete points of jumps. Therefore, the first collected induced voltage greater than or equal to the voltage threshold is not necessarily equal to the voltage threshold itself, and when the induced voltage is greater than or equal to the voltage threshold, the relative positions between the load device and the power supply device usually have been kept stable.
[0161] Step S802: Send the non-conductor loss to the power supply device, so that the power supply device determines the wireless power supply position among the at least one position according to the non-conductor loss sent by the load device at the at least one position, and generates a prompt message carrying the wireless power supply position, where the prompt message is used to prompt the user to place the load device at the wireless power supply position for wireless power supply.
[0162] Preferably, the step of sending the non-conductor loss to the power supply device, so that the power supply device determines the wireless power supply position among the at least one position according to the non-conductor loss sent by the load device at the at least one position, includes sending the non-conductor loss to the power supply device, so that the power supply device determines the position corresponding to the minimum non-conductor loss among the non-conductor losses sent by the load device at the at least one position as the wireless power supply position. For specific details regarding this, please refer to the foregoing embodiments.
[0163] Among them, the specific way to prompt the user to place the load device at the wireless power supply position for wireless power supply can be in the form of visual display (that is, displaying the position on the device screen), which is more intuitive and convenient to operate; it can also be in the form of audio broadcast, converting the relevant information of the wireless power supply position into audio and broadcasting it to the user, with a wider application scenario, being able to prompt the wireless charging position to the user even when the user is not looking at the load device, and being more user-friendly to visually impaired people.
[0164] In some embodiments of the present disclosure, the sending of the non-conductor loss to the power supply device includes:
[0165] In response to the non-conductor loss determined by the load device at the current position being the minimum non-conductor loss, sending the non-conductor loss determined at the current position to the power supply device, where the minimum non-conductor loss is the minimum non-conductor loss among the non-conductor losses determined by the load device at at least one position including the current position.
[0166] Specifically, when the load device is placed at the first position, it is necessary to send the non-conductor loss of the current position to the power supply device. During other placement processes except for the first placement, the non-conductor loss of the current position can be sent to the power supply device only when the non-conductor loss of the current position is not greater than each of the non-conductor losses of one or more previously placed positions. In other words, the load device sends the minimum non-conductor loss of the current position to the power supply device only when there is a possibility that the current position is determined as a wireless charging position. Thereby, the invalid data communication between the load device and the power supply device is reduced, and the execution efficiency of the method is improved.
[0167] Combining the above at least one embodiment, the following interaction steps can be obtained:
[0168] Step 1: The user places the load device at at least one position. The load device collects the induced voltage greater than or equal to the voltage threshold, determines the non-conductor loss according to the induced voltage, and sends the non-conductor loss determined at each position to the power supply device;
[0169] Step 2: The power supply device receives the non-conductor losses sent by the load device at at least one position, and determines the position corresponding to the minimum non-conductor loss among them as the wireless charging position;
[0170] Step 3: The power supply device generates a prompt message carrying the wireless power supply position. The prompt message is used to prompt the user to place the load device at the wireless power supply position for wireless power supply, and records the non-conductor loss corresponding to the wireless power supply position and the load device identifier;
[0171] Step 4: The user places the load device at the wireless power supply position. The load device sends the non-conductor loss determined at the current wireless power supply position to the power supply device (this non-conductor loss is less than or equal to the recorded non-conductor loss);
[0172] Step 5: The power supply device sends a notification to the load device to enable the load device to start supplying power to the load, and determines the current position as the wireless power supply position (that is, it can prompt the user that the current position is good and charging has started).
[0173] For the specific details and corresponding beneficial effects of the above embodiments of the second aspect and the above steps, please refer to the relevant parts of the foregoing embodiments, which will not be elaborated herein.
[0174] In a third aspect, another wireless power supply method applied to the load device side is provided.
[0175] In the embodiments of the first and second aspects, the collection of non-conductive losses is completed by the load device and sent to the power supply device by the load device. The power supply device determines the wireless charging position (i.e., the position with the minimum non-conductive loss) according to the non-conductive losses determined by the load device at at least one position, and generates a prompt message by the power supply device to enable the user to place the load device at the wireless power supply position for wireless power supply. Exemplarily, the embodiment of the first aspect can be applied to a mobile phone or a tablet computer with a wireless reverse charging function, and the embodiment of the second aspect can be applied to electronic accessories with a wireless charging function (such as wireless earphones, smart bracelets). However, in the actual application process, the steps involved in the embodiments of the first and second aspects can be completed on the same device, that is, in the embodiment of the third aspect, the collection of non-conductive losses, the determination of the wireless power supply position, and the generation of the prompt information are all completed by the load device, and the power supply device does not need to adapt to this. Specifically, in the embodiment of the third aspect, the power supply device can be a wireless charging board without a human-computer interaction function (such as a voice broadcast function or an image display function), and the load device can be a mobile phone or a tablet computer with a human-computer interaction function, etc.
[0176] Please refer to Figure 9 , the wireless power supply method includes:
[0177] Step 901: Record the non-conductive losses of the load device at at least one position, where the non-conductive losses are determined by the load device according to the voltage collected when the sensed voltage is greater than or equal to a voltage threshold, and the non-conductive losses are used to characterize the losses generated between the load device and the power supply device due to non-conductive factors, and the non-conductive factors include position offset.
[0178] The induced voltage of the load device can be the alternating current voltage induced at the receiving coil or the direct current voltage obtained after conversion by the AC / DC conversion module. It should be noted that since the process of the user bringing the load device close to the power supply device and keeping their relative positions stable usually only takes a short time, and there is a certain time interval for each polling of the induced voltage by the load device, the induced voltage obtained by each polling of the induced voltage by the load device is often a plurality of discrete points with jumps. Therefore, the first induced voltage greater than or equal to the voltage threshold collected for load power supply is not necessarily equal to the voltage threshold itself, and when the induced voltage is greater than or equal to the voltage threshold, the relative positions between the load device and the power supply device usually have been kept stable.
[0179] Step 902: Determine a wireless power supply position among the at least one position according to the non-conductive loss sent by the load device at the at least one position, and generate a prompt message carrying the wireless power supply position, where the prompt message is used to prompt the user to place the load device at the wireless power supply position for wireless power supply.
[0180] Preferably, determining the wireless power supply position among the at least one position according to the non-conductive loss sent by the load device at the at least one position includes determining the position corresponding to the minimum non-conductive loss among the non-conductive losses sent by the load device at the at least one position as the wireless power supply position. For specific details regarding this, please refer to the foregoing embodiments.
[0181] Among them, the specific way to prompt the user to place the load device at the wireless power supply position for wireless power supply can be in a visual display manner (i.e., displaying the position on the device screen), which is relatively intuitive and convenient to operate; it can also be in an audio broadcast manner, converting the relevant information of the wireless power supply position into audio and broadcasting it to the user, with a wider application scenario, being able to prompt the wireless charging position to the user even when the user is not looking at the load device, and being more friendly to visually impaired people.
[0182] In the embodiment of the present disclosure, the load device records non-conductive losses at at least one position, the non-conductive losses are determined by the load device according to the induced voltage collected when the induced voltage is greater than or equal to the voltage threshold, and the position corresponding to the minimum non-conductive loss among the non-conductive losses recorded by the load device at the at least one position is determined as the wireless power supply position; next, a prompt message carrying the wireless power supply position is generated, and the prompt message is used to prompt the user to place the load device at the wireless power supply position for wireless power supply. Since the non-conductive losses include the losses generated between the load device and the power supply device due to non-conductive factors such as position offset, the method provided by the present disclosure can determine the position among the at least one position where the load device has been placed with the least influence of non-conductive factors on wireless power supply, and prompt this position to the user so that the user can place the device at this position for wireless power supply, making the user more targeted during the wireless power supply process and being able to find the optimal wireless power supply position, effectively reducing the influence of non-conductive factors such as position offset on wireless power supply, thereby improving the charging power and the user experience during the wireless power supply process. At the same time, this method does not require the power supply device to perform corresponding adaptation to the method, improving the universality of the method.
[0183] In some embodiments of the present disclosure, please refer to Figure 10 , the method further includes:
[0184] Step S1001, record the non-conductive loss corresponding to the wireless power supply position and the device identifier corresponding to the power supply device;
[0185] Step S1002, in response to the device identifier corresponding to the power supply device being recorded and the non-conductive loss recorded at the current position of the load device being less than or equal to the non-conductive loss corresponding to the device identifier, determine the current position of the load device as the wireless power supply position;
[0186] And / or, in response to the device identifier corresponding to the power supply device being recorded and the non-conductive loss recorded at the current position of the load device being less than or equal to the non-conductive loss corresponding to the device identifier, supply power to the load and send a notification to the power supply device so that the power supply device starts to supply power to the load device.
[0187] In other words, when the wireless power supply position corresponding to the load device is determined, the non-conductive loss value corresponding to the wireless power supply position can be recorded, and in the subsequent process, in response to the device identifier corresponding to the load device being recorded, when the non-conductive loss sent at the current position of the load device is less than or equal to the previously recorded non-conductive loss value, the current position can be directly determined as the wireless power supply position or a notification can be directly sent to the power supply device so that the power supply device directly supplies power to the load device. In addition, the method can also refresh the non-conductive loss value determined in the above process and smaller than the previously recorded non-conductive loss value to the non-conductive loss record corresponding to the load device, so that in the next charging process of the load device, the smallest non-conductive loss is used as the threshold for judgment.
[0188] The above embodiments give the subsequent charging process after the wireless power supply position of the load device has been calibrated. In response to the current position being good (i.e., the non-conductive loss is less than the previously recorded value), the current position is directly prompted to the user or charging is directly started, thus realizing the complete process of calibration - application, enabling each load device to determine the corresponding non-conductive loss threshold after at least one calibration, so that each load device can perform wireless charging at the position most suitable for the power supply device and its own characteristics, improving the wireless charging power and maximizing the user experience.
[0189] It should be understood that the relevant details in the embodiments of the first aspect can also be applied to the embodiments of the second aspect and the third aspect. For example:
[0190] The method provided by the third aspect further includes:
[0191] Record the wireless power supply position and the device identifier corresponding to the load device;
[0192] In response to the device identifier corresponding to the load device being recorded, set the wireless power supply position corresponding to the device identifier as the wireless power supply position.
[0193] The method provided by the third aspect further includes:
