[0033] The technical solutions in the present application will be described below in conjunction with the accompanying drawings.

[0034] In order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, terms such as "first" and "second" are used to distinguish identical or similar items with basically the same functions and roles. Those skilled in the art can understand that terms such as "first" and "second" do not limit the quantity and execution order, and terms such as "first" and "second" do not necessarily mean different.

[0035] It should be noted that in the present application, words such as "exemplarily" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplarily" or "for example" in the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplarily" or "for example" is intended to present relevant concepts in a specific manner.

[0036] In addition, "at least one" means one or more, and "a plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone, where A and B may be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after. "At least one (item)" or its similar expression refers to any combination of these items, including any combination of single item (s) or plural item (s). For example, at least one (item) of a, b, and c may represent: a, or b, or c, or a and b, or a and c, or b and c, or a, b, and c, where a, b, and c may be single or multiple.

[0037] In order to make the purpose and technical solutions of the present application clearer and more intuitive, the wireless charging method, device, equipment, system, and storage medium provided by the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] Figure 1 It is a schematic diagram of application scenario 100 provided for the embodiments of the present application. As Figure 1As shown in the figure, the application scenario 100 includes a transmitting device 101 and a receiving device 102. The transmitting device 101 can wirelessly charge the receiving device 102. During the wireless charging process, the transmitting device 101 and the receiving device 102 can perform energy transfer and information interaction through electromagnetic fields or electromagnetic waves. The whole process can include steps such as initial detection, authentication, energy transfer, real-time monitoring and adjustment, and charging completion. Moreover, through communication protocols (such as the Qi standard) and security mechanisms, the efficiency and security of the charging process can be ensured.

[0039] However, the above method is not flexible. The Qi standard is a global wireless charging standard formulated by the Wireless Power Consortium (WPC). According to the Qi standard, the communication between the receiving device and the transmitting device is usually completely dominated by the receiving device. That is, only after the receiving device initiates an inquiry can the transmitting device reply with information, such as reply acknowledgment (ACK), negative acknowledgment (NACK), etc. During the wireless charging process, the transmitting device is the dominant party of power output. When there are some abnormal charging situations that require the transmitting device to stop energy output or require the receiving device to make some adjustments to eliminate or alleviate the abnormal situation, the transmitting device cannot notify the receiving device of the information related to the abnormality in a timely manner, resulting in unstable situations such as intermittent wireless charging.

[0040] The embodiments of the present application provide a wireless charging method, device, equipment, system, and storage medium. The transmitting device can wirelessly charge the receiving device. In the case of charging abnormality, a communication data packet is sent to the receiving device, so that the receiving device can receive the communication data packet from the transmitting device during the process of wireless charging through the transmitting device, and adjust the charging state based on the communication data packet. Among them, the communication data packet carries at least charging abnormality information and / or reference adjustment information corresponding to the charging abnormality information. The reference adjustment information is used to indicate power-off or adjustment of charging parameters. In other words, the transmitting device can actively send a communication data packet about the charging abnormality to the receiving device in the case of charging abnormality, so that the receiving device can flexibly adjust the charging state when learning about the charging abnormality, realizing highly flexible wireless charging and improving the stability of wireless charging.

[0041] The transmitting device involved in this application can be a charging stand or other devices that can convert electrical energy into an electromagnetic field and transmit it to the receiving device. Correspondingly, the receiving device involved in the embodiments of this application is a device that can receive energy from the electromagnetic field of the transmitting device and convert it into electrical energy for use by the device. The receiving device can be a mobile phone, watch, laptop, palmtop computer, mobile internet device (MID), personal computer (PC), wearable device, virtual reality (VR) device, augmented reality (AR) device, wireless terminal in self-driving, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, personal digital assistant (PDA), etc. The embodiments of this application do not limit this.

[0042] Exemplarily, Figure 2 FIG. is a schematic diagram of the system architecture of a transmitting device provided by an embodiment of this application.

[0043] As Figure 2 shown, the receiving device includes a processor 210 and a transceiver 220.

[0044] Optionally, the receiving device may further include a memory 230. The processor 210, the transceiver 220, and the memory 230 can communicate with each other through an internal connection path to transfer data. The memory 230 is used to store a computer program, and the processor 210 is used to call and run the computer program from the memory 230. The above-mentioned processor 210 and the memory 230 can be integrated into a processing device. More commonly, they are independent components. The processor 210 is used to execute the program code stored in the memory 230 to implement the above functions. Specifically, the memory 230 can also be integrated in the processor 210, or be independent of the processor 210.

[0045] In addition, in order to make the functions of the receiving device more complete, the receiving device may further include one or more of an input unit 260, a sensor 201, etc.

[0046] Optionally, the above-mentioned receiving device may further include a power supply 250 for supplying power to various components or circuits in the receiving device.

[0047] It can be understood thatFigure 2 The operations and / or functions of the respective modules in the receiving device shown are, respectively, for implementing the corresponding processes in the following method embodiments. For details, refer to the descriptions in the following method embodiments. To avoid repetition, the detailed descriptions are appropriately omitted here.

[0048] It can be understood that Figure 2 The processor 210 in the receiving device shown may include one or more processing units. For example, the processor 210 may include an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU), etc. Among them, different processing units may be independent devices or integrated in one or more processors.

[0049] A memory may also be provided in the processor 210 for storing instructions and data. In some embodiments, the memory in the processor 210 is a cache memory. This memory can save the instructions or data that the processor 210 has just used or recycled. If the processor 210 needs to use the instruction or data again, it can directly call it from the memory. This avoids repeated accesses, reduces the waiting time of the processor 210, and thus improves the efficiency of the system.

[0050] It can be understood that Figure 2The power supply 250 shown is used to supply power to the processor 210, the memory 230, the display unit 270, the input unit 260, the transceiver 220, etc. The transceiver 220 can provide solutions for wireless communications applied to the receiving device, including wireless local area networks (WLANs) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), infrared (IR), etc. The transceiver 220 can be one or more devices integrating at least one communication processing module. The memory 230 can be used to store computer-executable program codes, and the executable program codes include instructions. The memory 230 can include a program storage area and a data storage area. Among them, the program storage area can store an operating system, application programs required for at least one function, etc. The data storage area can store data created during the use of the receiving device, etc. In addition, the memory 230 can include high-speed random access memory, and can also include non-volatile memory, such as at least one disk storage device, a flash memory device, a universal flash storage (UFS), etc. The processor 210 executes various functional applications and data processing of the receiving device by running the instructions stored in the memory 230, and / or the instructions stored in the memory provided in the processor.

[0051] Figure 3 It is a schematic flowchart of a wireless charging method 300 provided by an embodiment of the present application. As Figure 3 shown, the method 300 may include the following steps:

[0052] S301, the transmitting device performs wireless charging on the receiving device. Correspondingly, the receiving device receives the wireless charging from the transmitting device.

[0053] The transmitting device is a device that can convert electrical energy into an electromagnetic field and transmit it to the receiving device. Correspondingly, the receiving device is a device that receives energy from the electromagnetic field of the transmitting device and converts it into electrical energy for the device to use. Among them, the transmitting device can include a transmitting coil, and the receiving device can include a receiving coil. Wireless charging can be performed by placing the receiving device in the charging area of the transmitting device, such as when the receiving coil is aligned with the transmitting coil.

[0054] Exemplarily, the transmitting coil in the transmitting device can generate an alternating magnetic field through an alternating current, and the receiving coil in the receiving device can sense the magnetic field and generate an electric current, thereby realizing wireless charging of the receiving device. That is, electrical energy is transferred between the transmitting coil and the receiving coil through the magnetic field and finally converted into direct current to charge the battery of the receiving device.

[0055] S302. When the charging of the transmitting device is abnormal, it sends a communication data packet to the receiving device. The communication data packet carries at least charging abnormality information and / or reference adjustment information corresponding to the charging abnormality information. The reference adjustment information is used to indicate power-off or adjustment of charging parameters. Correspondingly, during the process of wireless charging by the transmitting device, the receiving device receives the communication data packet from the transmitting device.

[0056] In some embodiments, the transmitting device can detect charging abnormalities in real time during the process of wireless charging the receiving device, so that when it is determined that there is a charging abnormality, it can promptly notify the receiving device of the charging abnormality, enabling the receiving device to adjust the charging state to alleviate or solve the corresponding charging abnormality.

[0057] In some embodiments, the transmitting device can periodically detect charging abnormalities during the process of wireless charging the receiving device, so as to avoid excessive power consumption caused by frequent detection and high device temperature affecting the charging performance. At the same time, when it is determined that there is a charging abnormality, it can promptly notify the receiving device of the charging abnormality, enabling the receiving device to adjust the charging state to alleviate or solve the corresponding charging abnormality.

[0058] In some embodiments, the transmitting device can also detect charging abnormalities when it is determined that it is in a preset charging stage, so that when it is determined that there is a charging abnormality, it can promptly notify the receiving device of the charging abnormality, enabling the receiving device to adjust the charging state to alleviate or solve the corresponding charging abnormality and improve the charging stability of the preset charging stage.

[0059] It should be understood that during the wireless charging process, the probability of charging abnormalities in different charging stages is different. To improve the charging stability of the wireless charging stage with a higher probability of charging abnormalities, the above preset charging stage can be the charging stage with a higher probability of charging abnormalities during the wireless charging process.

[0060] In some embodiments, the charging stages of the above wireless charging can include an initial charging stage, a charging ongoing stage, and a charging end stage. The above preset charging stage can be at least one of the above initial charging stage, charging ongoing stage, and charging end stage.

[0061] It should be understood that the charging phases of the wireless charging shown above are merely exemplary. In addition, the wireless charging process may further include multiple other different charging phases, which are not limited in this application.

[0062] In some embodiments, the transmitting device may also perform detection of charging anomalies in response to an anomaly detection operation. This anomaly detection operation may be an operation on the transmitting device. For example, if the transmitting device is provided with an anomaly detection function button, the transmitting device may perform the above-mentioned charging anomaly detection when detecting a touch operation on the anomaly detection function button.

[0063] In some embodiments, the transmitting device may also perform detection of charging anomalies based on a communication data packet carrying a charging anomaly detection instruction.

[0064] In a possible case, the receiving device is provided with an anomaly detection function button. The receiving device may send a communication data packet carrying a charging anomaly detection instruction to the transmitting device when detecting a touch operation on the anomaly detection function button. Correspondingly, the transmitting device may receive the communication data packet and perform charging anomaly detection based on the charging anomaly detection instruction.

[0065] In another possible case, the receiving device may send a communication data packet carrying a charging anomaly detection instruction to the transmitting device in a preset application scenario. Correspondingly, the transmitting device may receive the communication data packet and perform charging anomaly detection based on the charging anomaly detection instruction.

[0066] Exemplarily, the preset application scenario may be a high-power, high-load application scenario, such as a game scenario, a video rendering scenario, a multi-tasking scenario, etc., to improve the stability of wireless charging in the high-power, high-load application scenario.

[0067] In some embodiments, when the communication data packet sent to the receiving device carries a reference adjustment message corresponding to charging anomaly information, the reference adjustment information may be determined by the transmitting device based on the charging anomaly information and reference information. The reference information includes different charging anomaly information and the reference adjustment information corresponding to each charging anomaly information, that is, the adjustment operation indicated by the reference adjustment information is an adjustment operation that can alleviate or solve the corresponding charging anomaly.

[0068] The reference information may be obtained through pre-testing, that is, determined by performing different adjustment operations in different charging anomaly situations.

[0069] S303. The receiving device adjusts the charging state based on the communication data packet.

[0070] When the above communication data packet carries reference adjustment information corresponding to charging anomaly information, the receiving device may perform the adjustment operation indicated by the reference adjustment information, such as powering off or adjusting charging parameters, so as to relieve or solve the charging anomaly by adjusting the charging state.

[0071] When the above communication data packet carries charging anomaly information, the receiving device may perform the reference adjustment information corresponding to the charging anomaly information to achieve adjustment of the charging state.

[0072] In some embodiments, the receiving device may determine the reference adjustment information corresponding to the charging anomaly information based on the reference information and the charging anomaly information carried in the communication data packet. Wherein, the reference information may include different charging anomaly information and the reference adjustment information corresponding to each charging anomaly information.

[0073] When the above communication data packet carries charging anomaly information and the reference adjustment information corresponding to the charging anomaly information, the receiving device may perform the reference adjustment information corresponding to the charging anomaly information to achieve adjustment of the charging state.

[0074] Exemplarily, when powering off is indicated by the above reference adjustment information, the receiving device may perform a power-off operation to switch the charging state from charging to charging end, so as to relieve or solve the charging anomaly.

[0075] Exemplarily, when adjusting the charging parameter is indicated by the above reference adjustment information, the receiving device may adjust the corresponding charging parameter to switch the charging state from charging based on the current charging parameter to charging based on the adjusted charging parameter, so as to relieve or solve the charging anomaly.

[0076] In this application, the transmitting device performs wireless charging on the receiving device. In the case of a charging anomaly, a communication data packet may be sent to the receiving device, so that the receiving device receives the communication data packet from the transmitting device during the process of wireless charging through the transmitting device, and adjusts the charging state based on the communication data packet. Wherein, the communication data packet carries at least charging anomaly information and / or reference adjustment information corresponding to the charging anomaly information, and the reference adjustment information is used to indicate powering off or adjusting the charging parameter. In other words, the transmitting device may actively send a communication data packet about the charging anomaly to the receiving device in the case of a charging anomaly, so that the receiving device can flexibly adjust the charging state when learning about the charging anomaly, achieving highly flexible wireless charging and improving the stability of wireless charging.

[0077] In some embodiments, different types of charging anomalies may occur during wireless charging. The transmitting device may send a communication data packet corresponding to the anomaly type to the receiving device based on the anomaly type of the charging anomaly. Among them, the communication data corresponding to different anomaly types carries different types of charging anomaly information and / or reference adjustment information for indicating different adjustment operations, so that the receiving device can perform an adjustment operation on the charging state matching the anomaly type based on the communication data packet.

[0078] Figure 4 It is a schematic flowchart of a wireless charging method 400 provided by an embodiment of the present application. As Figure 4 shown, the method 400 may include the following steps:

[0079] S401, the transmitting device performs wireless charging on the receiving device. Correspondingly, the receiving device receives wireless charging from the transmitting device.

[0080] S402, when the charging anomaly occurs, the transmitting device sends a communication data packet corresponding to the anomaly type to the receiving device based on the anomaly type of the charging anomaly. The communication data corresponding to different anomaly types carries different types of charging anomaly information and / or reference adjustment information for indicating different adjustment operations. Correspondingly, during the process of wireless charging by the transmitting device, the receiving device receives the communication data packet corresponding to the anomaly type from the transmitting device.

[0081] In some embodiments, the charging anomaly may include a charging anomaly whose anomaly type needs to be alleviated or resolved by stopping charging (such as the first type of charging anomaly) and a charging anomaly whose anomaly type can be alleviated or resolved without stopping charging (such as the second type of charging anomaly).

[0082] Exemplarily, in the case of the first type of charging anomaly, the transmitting device may send a communication data packet corresponding to the first type of charging anomaly to the receiving device based on the first type of charging anomaly. The communication data corresponding to the first type of charging anomaly carries the first type of charging anomaly information and / or reference adjustment information for indicating power-off.

[0083] Exemplarily, in the case of the second type of charging anomaly, the transmitting device may send a communication data packet corresponding to the second type of charging anomaly to the receiving device based on the second type of charging anomaly. The communication data corresponding to the second type of charging anomaly carries the second type of charging anomaly information and / or reference adjustment information for indicating non-power-off, such as reference adjustment information for indicating adjustment of charging parameters.

[0084] S403, the receiving device adjusts the charging state based on the communication data packet.

[0085] In the case of receiving a communication data packet carrying the first type of charging anomaly information and / or the first reference adjustment information, the receiving device may perform the adjustment operation indicated by the first reference adjustment information, such as powering off, to alleviate or resolve the first type of charging anomaly.

[0086] In the case of receiving a communication data packet carrying the second type of charging anomaly information and / or the second reference adjustment information, the receiving device may perform the adjustment operation indicated by the second reference adjustment information, such as adjusting the charging parameters, to alleviate or resolve the second type of charging anomaly.

[0087] In an embodiment of the present application, during the wireless charging of the receiving device by the transmitting device, charging anomalies of different types can be detected, and the charging anomalies of different types can be timely sent to the receiving device through a communication data packet. Correspondingly, the receiving device can receive the above communication data packet during the process of receiving wireless charging from the transmitting device, so as to learn about the existing charging anomalies based on the communication data packet, timely adjust the charging state, alleviate or resolve the charging anomalies, achieve highly flexible wireless charging, and improve the stability of wireless charging.

[0088] Taking the existence of the first type of charging anomaly as an example, the wireless charging method provided by the present application will be described in detail below.

[0089] Figure 5 It is a schematic flowchart of a wireless charging method 500 provided by an embodiment of the present application. As Figure 5 shown, the method 500 may include the following steps:

[0090] S501, perform wireless charging on the receiving device.

[0091] S502, determine whether there is a first type of charging anomaly.

[0092] In some embodiments, the transmitting device may also determine whether there is a first type of charging anomaly by judging at least one of the magnitude relationship between the power loss and the first power loss threshold, the reception situation of the control error packet CEP, the reception situation of the received power packet RPP, and the magnitude relationship between the device temperature and the temperature threshold.

[0093] In some embodiments, to avoid problems such as additional power loss caused by metal foreign objects between the transmitting device and the receiving device, which may lead to abnormal heating, damage to the device, or safety hazards, the transmitting device can determine whether there is a metal foreign object through the magnitude relationship between the power loss and the first power loss threshold, and the first power loss threshold can be used to indicate the value of the minimum power loss for triggering foreign object detection FOD, so as to timely judge whether there is a first type of charging anomaly. And when it is determined that there is a charging anomaly, the receiving device is timely notified to enable the receiving device to alleviate or resolve the existing charging anomaly by adjusting the charging state.

[0094] In some embodiments, a Control Error Packet (CEP) is a control signal sent by a receiving device to a transmitting device for feedback on the charging state, power demand, or error information. To avoid the problems that the transmitting device fails to receive the CEP in time, which may lead to the interruption of the charging process, a decrease in charging efficiency, and the inability to take protection measures in a timely manner in the case of overheating, the transmitting device can determine whether there is a first type of charging anomaly in a timely manner based on the reception situation of the CEP, and when it determines the existence of a charging anomaly, notify the receiving device in a timely manner, so that the receiving device can relieve or solve the existing charging anomaly by adjusting the charging state.

[0095] In some embodiments, a Received Power Packet (RPP) is used to feedback the power state of the receiving device and adjust the output power of the transmitting device. To avoid the problems that the transmitting device fails to receive the RPP, resulting in the interruption of the charging process, a decrease in charging efficiency, and the inability to take protection measures in a timely manner for feedback error information (such as overheating or overvoltage), the transmitting device can determine whether there is a first type of charging anomaly in a timely manner based on the reception situation of the RPP within a preset time window, and when it determines the existence of a charging anomaly, notify the receiving device in a timely manner, so that the receiving device can relieve or solve the existing charging anomaly by adjusting the charging state.

[0096] In some embodiments, to avoid the problems that the device is damaged or there are safety hazards due to excessive device temperature, the transmitting device can determine whether there is a first type of charging anomaly in a timely manner based on the relationship between the device temperature and the temperature threshold, and when it determines the existence of a charging anomaly, notify the receiving device in a timely manner, so that the receiving device can relieve or solve the existing charging anomaly by adjusting the charging state.

[0097] S503. In the case of a first type of charging anomaly, send a communication data packet carrying the first type of charging anomaly information and / or the first reference adjustment information to the receiving device, where the first reference adjustment information is used to indicate power-off, so that the receiving device adjusts the charging state based on the communication data packet.

[0098] In some embodiments, the receiving device can determine the existence of the above-mentioned first type of charging anomaly when it determines that the power loss is greater than or equal to the first power loss threshold; does not receive the CEP from the receiving device within a preset time window; does not receive the RPP from the receiving device within a preset time window; and the device temperature is greater than or equal to the temperature threshold.

[0099] In some embodiments, the above-mentioned first type of charging anomaly information includes at least one of the following: the power loss is greater than or equal to a first power loss threshold, where the first power loss threshold is used to indicate the value of the minimum power loss for triggering foreign object detection (FOD); no Charging End Packet (CEP) is received from the receiving device within a preset time window; no Receiver Power Profile (RPP) is received from the receiving device within a preset time window; the device temperature is greater than or equal to a temperature threshold. Correspondingly, the above-mentioned first reference adjustment information may be information indicating power-off.

[0100] It should be understood that the above-mentioned first type of charging anomaly information shown is merely exemplary. In addition, the first type of charging anomaly information may also include charging anomaly information corresponding to other charging anomalies that need to be alleviated or resolved by power-off. The present application does not make any limitations in this regard.

[0101] In the embodiments of the present application, during the wireless charging process of the receiving device, the transmitting device can flexibly determine whether there is currently a charging anomaly of a type that requires power-off to resolve or alleviate through at least one of the status of charging parameters, such as the relationship between the power loss and the first power loss threshold, the reception situation of the CEP, the reception situation of the RPP, and the relationship between the device temperature and the temperature threshold. And when it is determined that there is such a charging anomaly, the transmitting device can send the information related to this type of charging anomaly to the receiving device through a communication data packet, so that the receiving device can learn about the existing charging anomaly and can timely adjust the charging status, such as performing a power-off operation, to adjust from the charging state to the end-of-charging state, so as to alleviate or resolve the above-mentioned charging anomaly, achieving highly flexible wireless charging and improving the stability of wireless charging.

[0102] Next, taking the existence of a second type of charging anomaly as an example, the wireless charging method provided by the present application will be described in detail.

[0103] Figure 6 is a schematic flowchart of a wireless charging method 600 provided by an embodiment of the present application. As Figure 6 shown, the method 600 may include the following steps:

[0104] S601, perform wireless charging on the receiving device.

[0105] S602, determine whether there is a second type of charging anomaly.

[0106] In some embodiments, the transmitting device can determine whether there is a second type of charging anomaly by judging at least one of the relationship between the power loss and the second power loss threshold, the reception situation of the communication packet from the receiving device, the relationship between the voltage and the voltage threshold, and the output capacity situation.

[0107] Optionally, when the above-mentioned second type of charging anomaly information indicates that the power loss is greater than or equal to the second power loss threshold and / or the voltage is lower than the voltage threshold, before sending a communication data packet carrying the second type of charging anomaly information and / or the second reference adjustment information to the receiving device, the transmitting device may also reduce the output energy and stop responding to CEP from the receiving device within a preset duration.

[0108] S603. When there is a second type of charging anomaly, send a communication data packet carrying the second type of charging anomaly information and / or the second reference adjustment information to the receiving device, where the second reference adjustment information is used to indicate adjustment of charging parameters so that the receiving device adjusts the charging state based on the communication data packet.

[0109] In some embodiments, the transmitting device may determine that there is a second type of charging anomaly when at least one of the following conditions is met: no communication packet from the receiving device is received within a preset duration; the power loss is greater than or equal to the second power loss threshold, where the second power loss threshold is used to indicate the minimum power loss value for critically triggering foreign object detection (FOD); the voltage is lower than the voltage threshold; the output capability changes.

[0110] In some embodiments, the above-mentioned second type of charging anomaly information may include at least one of the following: no communication packet from the receiving device is received within a preset duration; the power loss is greater than or equal to the second power loss threshold, where the second power loss threshold is used to indicate the minimum power loss value for critically triggering foreign object detection (FOD); the voltage is lower than the voltage threshold; the output capability changes.

[0111] In some embodiments, the adjustment operation of the charging parameters at least includes adjusting the received power, which is not limited in this application.

[0112] It should be understood that the above-mentioned second type of charging anomaly information shown is merely exemplary. In addition, the second type of charging anomaly information may also include charging anomaly information corresponding to other charging anomalies that do not need to be alleviated or resolved by powering off, which is not limited in this application.

[0113] In the embodiments of the present application, during the wireless charging process of the receiving device, the transmitting device can flexibly determine whether there is a charging anomaly of an abnormal type that can be resolved or alleviated without powering down based on at least one of the status of charging parameters, such as the reception of communication packets, the relationship between power loss and the second power loss threshold, the relationship between voltage and the voltage threshold, and the change in output capacity. And when it is determined that there is such a charging anomaly, the transmitting device can send information related to such a charging anomaly to the receiving device through a communication data packet, so that the receiving device can learn about the existing charging anomaly and can timely adjust the charging status, such as performing an adjustment operation on the charging parameters, to adjust the charging status based on the current charging parameters to the charging status based on the adjusted charging parameters, so as to alleviate or resolve the above-mentioned charging anomaly, realizing highly flexible wireless charging and improving the stability of wireless charging.

[0114] In some embodiments, the priorities of charging anomalies of different abnormal types are different. For example, the priority of the first type of charging anomaly is higher than that of the second type of charging anomaly. The transmitting device can first determine whether there is a first type of charging anomaly, and then determine the second type of charging anomaly when there is no first type of charging anomaly. For specific details, please refer to the following description of Figure 7 the

[0116] S701, perform wireless charging on the receiving device.

[0117] S702, determine whether there is a first type of charging anomaly.

[0118] S703, when there is a first type of charging anomaly, send a communication data packet carrying the first type of charging anomaly information and / or the first reference adjustment information to the receiving device, so that the receiving device adjusts the charging status based on the communication data packet carrying the first type of charging anomaly information and / or the first reference adjustment information, and the first reference adjustment information is used to indicate powering down.

When there is a second type of charging anomaly, send a communication data packet carrying the second type of charging anomaly information and / or second reference adjustment information to the receiving device, so that the receiving device adjusts the charging state based on the communication data packet carrying the second type of charging anomaly information and / or second reference adjustment information, where the second reference adjustment information is used to indicate the adjustment of charging parameters.

[0122] In the embodiment of the present application, during the wireless charging of the receiving device by the transmitting device, it can sequentially determine whether there is a charging anomaly of the corresponding anomaly type according to the priority of the charging anomalies of different anomaly types. For example, the priority of the first type of charging anomaly is higher than that of the second type of charging anomaly. The transmitting device can first determine whether there is a first type of charging anomaly, and then determine the second type of charging anomaly when there is no first type of charging anomaly, so as to avoid the impact of the high power consumption caused by determining the charging anomaly on the charging performance, and at the same time reduce the complexity of the receiving device to alleviate or solve the charging anomaly when there is a charging anomaly subsequently.

[0123] The following takes the transmitting device determining whether there is a first type of charging anomaly by judging at least one of the relationship between the power loss and the first power loss threshold, the reception situation of the control error packet CEP, the reception situation of the received power packet RPP, and the relationship between the device temperature and the temperature threshold, and determining whether there is a second type of charging anomaly by judging at least one of the relationship between the power loss and the second power loss threshold, the reception situation of the communication packet from the receiving device, the relationship between the voltage and the voltage threshold, and the output capacity situation as an example to describe in detail the wireless charging method provided by the present application.
