[0053] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying 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 implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0054] The wireless charging method provided in the embodiments of the present disclosure is applied to the scenario of wireless charging of a terminal, for example, to the scenario of wireless charging of a mobile phone.

[0055] A wireless charging method provided by an embodiment of the present disclosure, the wireless charging technical solution consists of a wireless charging transmitter and a wireless charging receiver. Energy and information are usually transmitted through coils. At the wireless charging transmitter, the electrical energy is converted into electromagnetic waves through the coil; at the wireless charging receiver, the electromagnetic waves are converted into electrical energy, and then converted into direct current to charge the battery of the terminal. One end of the adapter is connected to a power source, and the other end is connected to a coil, which is used to power the coil of the wireless charging transmitter. The access point (AP) is a control module of the charging receiver, which can collect battery power information, control the parameter settings of the charging receiver, and send the battery power information to the charging transmitter. For ease of description, the charging transmitter in the following embodiments includes a transmitter of a coil for transmitting electrical energy and an adapter for powering the coil, and the charging receiver includes a coil for transmitting electrical energy, a rectifier circuit and an AP.

[0056] Since the AP cannot interact with the adapter's power information, the charging transmitter cannot synchronize the power adjustment information with the charging receiver in time after the power of the charging transmitter changes. As a result, the charging receiver cannot adaptively adjust its power level in time, which may trigger the over-power protection mechanism to disconnect the charging. For example, when the adapter of the wireless charging transmitter continues to charge at a higher power, it may cause the temperature to rise, triggering the over-temperature protection (OTP) and reducing the charging power of the wireless charging transmitter.

[0057] In order to solve this problem, the present disclosure proposes a wireless charging method.

[0058] Figure 1 is a flow chart of a wireless charging method applied to a charging transmitter according to an exemplary embodiment. Figure 1 As shown, the method includes steps S11 to S12.

[0059] In step S11, the charging power information of the wireless charging transmitter is obtained.

[0060] During the wireless charging process, the charging power information of the wireless charging transmitter is obtained so that when the charging power of the transmitter changes, the power information can be synchronized to the receiving end in time to avoid power mismatch problems.

[0061] In step S12, when information transmission is supported between the wireless charging transmitter and the wireless charging receiver, first power information is sent to the wireless charging receiver, where the first power information is used to indicate power information after the charging power of the wireless charging transmitter changes.

[0062] During the wireless charging process, the charging power of the wireless charging transmitter may change, and the charging transmitter identifies the power adjustment information. When information transmission is supported between the wireless charging transmitter and the wireless charging receiver, the wireless charging transmitter sends the first power information to the wireless charging receiver. The first power information can be a reduced charging power or a default non-reduced power.

[0063] In the method of the embodiment of the present disclosure, the communication between the control module AP of the charging receiving end and the adapter of the charging transmitting end can be indirectly realized by signal transmission between the chip of the wireless charging transmitting end and the chip of the wireless charging receiving end. For example, wireless communication protocols such as ASK (Amplitude Shift Keying) or FSK (Frequency-shiftkeying) can be used to transmit signals. These protocols allow the transmission of communication signals between the chip of the charging transmitting end and the chip of the receiving end.

[0064] In the disclosed embodiment, when the power of the wireless charging transmitter changes, the changed power information is promptly communicated to the charging receiver. The wireless charging transmitter can promptly learn about the power changes of the charging transmitter and make corresponding adjustments based on the power information in the response information. This ensures that the charging process between the charging transmitter and the receiver remains synchronized and coordinated, improves charging efficiency, and avoids problems such as charging interruption due to power mismatch.

[0065] In the wireless charging process between the wireless charging transmitter and the wireless charging receiver, the control module AP of the charging receiver generally cannot communicate directly with the charging transmitter adapter. In view of this, an embodiment of the present disclosure provides a method for information transmission between a wireless charging transmitter and a wireless charging receiver.

[0066] In the embodiment of the present disclosure, if the wireless charging transmitting end receives a power packet sent by the wireless charging receiving end, information transmission is supported between the wireless charging transmitting end and the wireless charging receiving end.

[0067] Among them, the power packet is a data packet that carries battery power information. Through the transmission of the power packet, the wireless charging transmitter can communicate with the receiver for corresponding control and adjustment. The power packet can be sent in a transparent transmission manner. Pass-through refers to a transmission method in which the transmitted data is not modified or processed during the communication process, and the data is directly transmitted from the sender to the receiver. By transparently transmitting the power packet, the accurate transmission of the power packet information and the integrity of the data can be ensured, without additional parsing or modification of the power packet, which can avoid information loss or distortion. And because the transparent transmission of the power packet does not require additional parsing and processing steps, the efficiency and response speed of communication can be improved.

[0068] In the disclosed embodiment, by receiving the power packet sent by the wireless charging receiving end, it is determined that the wireless charging transmitting end and the wireless charging receiving end support information transmission. And the interaction and information transmission between the wireless charging transmitting end adapter and the wireless charging receiving end control module AP are indirectly realized. This timely interaction and information transmission enables the wireless charging receiving end to respond to the power reduction demand of the transmitting end in a timely manner, avoiding the problem of over-power protection disconnection, and also improving charging efficiency and safety.

[0069] In one embodiment, after receiving the power packet sent by the receiving end, the wireless charging transmitter determines that information transmission is supported between the wireless charging transmitter and the wireless charging receiving end, and sends a first response message to the receiving end. The first response message includes first power information, and the first response message can be sent in the form of a power packet. The first power information includes the power change information of the wireless charging transmitter, which is used to instruct the wireless charging receiving end to make corresponding adjustments based on this information. The first power information can be a reduced charging power or a default non-reduced power.

[0070] In the embodiment of the present disclosure, after receiving the power packet sent by the charging receiving end, the charging transmitting end determines the first power information of the charging transmitting end according to the recorded power information, and sends the first response information containing the first power information to the charging receiving end. By sending the power packet in this way, the wireless charging transmitting end can timely convey the information of charging power adjustment to the receiving end, avoiding the problem of reducing charging efficiency or causing charging interruption due to power mismatch.

[0071] Figure 2 is a flow chart of a wireless charging method applied to a charging receiving end according to an exemplary embodiment. Figure 2 As shown, the method includes steps S41 to S42.

[0072] In step S41, when information transmission is supported between the wireless charging transmitter and the wireless charging transmitter, first power information sent by the wireless charging transmitter is received.

[0073] The first power information is used to indicate the power information after the charging power of the wireless charging transmitting end changes.

[0074] In step S42, the power of the wireless charging transmitter is adjusted to a target power, where the target power is determined based on the first power information.

[0075] In the disclosed embodiment, during the wireless charging process, the wireless charging receiving end communicates with the transmitting end through wireless communication to timely learn the power status of the wireless charging transmitting end. This enables the charging receiving end to make corresponding adjustments based on the current power information of the charging transmitting end. This ensures that the charging process between the charging receiving end and the transmitting end remains synchronized and coordinated, improves charging efficiency, and avoids problems such as charging interruption due to power mismatch.

[0076] In one embodiment, the situation in which information transmission is supported between the wireless charging receiving end and the wireless charging transmitting end includes sending a power packet to the wireless charging transmitting end. The power packet is a data packet containing power information. For example, in response to a change in the power of the terminal, the AP sends an instruction to transparently transmit the power packet to the wireless charging receiving end chip, and the receiving end sends the power packet to the transmitting end for information transmission.

[0077] In the embodiment of the present disclosure, during the wireless charging process, in order to achieve power matching between the wireless charging receiving end and the transmitting end, the wireless charging receiving end sends a power packet to the transmitting end. By sending the power packet in real time, the interaction and information transmission between the wireless charging transmitting end adapter and the wireless charging receiving end control module AP are indirectly realized.

[0078] In one embodiment, receiving the first power information sent by the wireless charging transmitter includes receiving first response information, the first response information includes the first power information, wherein the first response information is a response of the wireless charging transmitter to the power packet.

[0079] In the disclosed embodiment, after the wireless charging transmitter responds to the power packet, the receiving end receives the first response information sent by the transmitting end to the receiving end, and parses the current power information of the transmitting end through the first power information in the first response information. In this way, the wireless charging receiving end can timely understand the power status of the transmitting end. This enables the charging receiving end to make corresponding adjustments according to the current power level information of the charging transmitting end.

[0080] Figure 3 is a flow chart showing a method for determining target power applied to a charging receiving end according to an exemplary embodiment. Figure 3 As shown, the method includes steps S71 to S72.

[0081] In step S71, a first power mode of the wireless charging receiving end is determined according to the first power information.

[0082] When the wireless charging receiving end receives the first response information including the power information of the transmitting end sent by the transmitting end, the charging receiving end determines its own first power mode based on the first power information of the transmitting end, wherein there is a corresponding relationship between the first power information and the first power mode.

[0083] In step S72, the target power is determined based on the first power mode.

[0084] After determining the first power mode, the wireless charging receiving end adjusts the power of the receiving end to a power mode corresponding to the transmitting end.

[0085] In the disclosed embodiment, a more reasonable power matching can be achieved through the correspondence between the power mode of the wireless charging receiving end and the power information of the transmitting end. This means that the wireless charging receiving end can adjust its own power mode according to the power information of the transmitting end to adapt to different charging requirements and conditions. This flexibility enables the wireless charging system to achieve reasonable power control in different charging scenarios and improve the efficiency of wireless charging.

[0086] Figure 4 The present invention is a flow chart of a method for determining a target power of a wireless charging receiving end according to an exemplary embodiment.

[0087] In step S81, if the first power information complies with the temperature control strategy, the power corresponding to the first power mode is determined as the target power.

[0088] After the wireless charging receiving end determines the first power mode corresponding to it according to the first power information received from the transmitting end, it also needs to adjust the power in combination with the current heat information of the receiving end and its own temperature control strategy. If the first power information meets the temperature control strategy, the power corresponding to the first power mode is determined as the target power.

[0089] In step S82, if the first power information does not comply with the temperature control strategy, the power adjusted according to the temperature control strategy is used as the target power.

[0090] If the first power information does not meet the temperature control strategy, the power will be adjusted according to the temperature control strategy, and the adjusted power will be used as the target power. This means that the power adjustment information of the wireless charging transmitter does not meet the temperature control requirements of the receiver, and the receiver control module will still adjust the power according to the temperature control strategy to ensure that the temperature during charging is within a reasonable range.

[0091] In the embodiment of the present disclosure, the power adjustment information of the transmitting end and the temperature control strategy of the receiving end are comprehensively considered in the process of adjusting the power mode of the wireless charging receiving end, so as to ensure the power adaptability and temperature control safety during the charging process to the greatest extent.

[0092] Figure 5 is a flow chart of a method for reducing power of a terminal wireless charging based on power packet communication according to an exemplary embodiment. Figure 5 As shown, in one implementation of the embodiment of the present disclosure, the method for reducing power of terminal wireless charging based on power packet communication is:

[0093] After connecting to the power source, the charging receiver starts to run, checks the battery charge change, and the AP generates a command to instruct the wireless charging receiver to send a power packet to the transmitter in a transparent manner. After the wireless charging transmitter starts running, it detects that the transmitter adapter is running at rated power. The charging transmitter divides the operating power level into F0, and sends F0 to the wireless charging receiver after receiving the power packet sent by the receiver. After receiving the power information F0, the wireless charging receiver parses it and sets the target power of the wireless charging receiver to the A gear corresponding to the current transmitter.

[0094] During operation, the internal temperature of the charging transmitter will continue to rise, triggering the OTP mechanism and triggering the power update instruction soft_reset of the charging transmitter. The charging transmitter will reduce power and operate at a power level of F1, which will be transparently transmitted to the charging receiver. The wireless charging receiver sets the target power to the B gear corresponding to the current transmitter according to the operating power level F1 after the current charging transmitter reduces power.

[0095] The charging transmitter is in continuous operation. As the temperature continues to rise, OTP is triggered again, and the power update instruction soft_reset of the charging transmitter is triggered again. The charging transmitter reduces power again. The power level of the wireless charging transmitter at this time is classified as F2 and transparently transmitted to the receiving end. The wireless charging receiving end sets the target power to the C gear corresponding to the current transmitter according to the operating power level F2 of the current charging transmitter after the power is reduced again.

[0096] In one implementation of the embodiment of the present disclosure, a wireless charging transmitter chip Tx and a wireless charging receiver chip Rx are included. When the charging transmitter Tx is in the default state, when the charging transmitter Tx receives a power packet, it replies F0 to the charging receiver Rx; when the charging transmitter Tx recognizes that the power of the charging transmitter is reduced by 1 gear, the charging transmitter Tx receives the power packet and replies F1 to the charging receiver Rx; when the charging transmitter Tx recognizes that the power of the charging transmitter is reduced by 1 gear again, the charging transmitter Tx receives the power packet and replies F2 to the charging receiver Rx; the charging receiver receives the power information of the charging transmitter Tx and configures the corresponding power gear. For example, the gear A is configured to the gear C, and the current FCC of the charging receiver is determined based on the heat value thermal combined with the temperature control strategy.

[0097]

[0098] As described in the above table, in different scenarios, the real-time power level of the adapter is determined, and the real-time power level of the adapter is identified at the transmitter Tx. The AP at the receiving end needs to control the power level of the receiving end according to the power information of the wireless charging transmitter.

[0099] In scenario 1, when the adapter power of the transmitter is the default unreduced power, that is, the rated power, the transmitter Tx electrically connected to the adapter determines the current output power of the adapter and determines that the power level is F0. The transmitter sends the power level F0 information to the receiver Rx. In the AP at the Rx end, based on the power packet and the power level F0, the AP determines that the power level of the receiver remains at the default A level.

[0100] In scenario 2, as the adapter runs, the temperature inside the adapter rises. When the temperature is higher than the set threshold, the OTP over-temperature protection is triggered to reduce the output power of the adapter. If the power of the adapter is reduced by 1 level, the transmitter determines that the adapter level is F1. The transmitter sends the power level information F1 to the receiver Rx. In the AP at the Rx end, based on the power packet and power level F1, the AP determines that the power level of the receiver is level B.

[0101] In scenario 3, after the adapter has been protected from over-temperature and its power is reduced by one level, it continues to run. The internal temperature of the adapter rises again and exceeds the set temperature threshold. The adapter then reduces its output power by one level again.

[0102] Figure 6 FIG. 1 is a flow chart of a wireless charging method applied to a charging transmitter according to an exemplary embodiment. Figure 6As shown, the method includes steps S91 to S94.

[0103] In step S91, a power packet sent by a wireless charging receiving end is received.

[0104] The wireless charging transmitter receives the power packet sent by the wireless charging receiver, wherein the power packet is a data packet containing current power information.

[0105] In step S92, before adjusting the charging power, a second response message is sent to the wireless charging receiving end.

[0106] After receiving the power packet sent by the wireless charging receiving end, the wireless charging transmitting end determines the second power information for adjusting the charging power in combination with the current power information, and includes the second power information in the second response information and sends it to the wireless charging receiving end. The second power information can be a power that is increased or decreased based on the current charging power.

[0107] In step S93, the third response information sent by the wireless charging receiving end is received.

[0108] The third response information is the indication information fed back by the wireless charging receiving end after the wireless charging transmitting end actively sends the charging power information to be adjusted to the wireless charging receiving end.

[0109] In step S94, when the third response information indicates that the wireless charging receiving end allows the wireless charging transmitting end to adjust the power to the target power, the power of the wireless charging transmitting end is adjusted to the target power, wherein the target power is the power indicated by the second power information.

[0110] After receiving the third response information sent by the wireless charging receiving end, the wireless charging transmitting end learns that the wireless charging receiving end allows the power adjustment of the wireless charging transmitting end, and uses the power indicated by the second power information as the current charging power for wireless charging.

[0111] In the disclosed embodiment, the wireless charging transmitter can actively communicate with the receiver to negotiate power adjustment to ensure the efficiency and safety of the charging process. By receiving the third response information from the receiver, the transmitter clearly knows whether the power can be adjusted to the target power, avoiding unnecessary and unreasonable power adjustment that causes power mismatch between the transmitter and the receiver.

[0112] Figure 7 is a flow chart of a wireless charging method applied to a charging receiving end according to an exemplary embodiment. Figure 7 As shown, the method includes steps S101 to S103.

[0113] In step S101, a power packet is sent to a wireless charging transmitter.

[0114] The wireless charging receiving end sends a power packet to the wireless charging transmitting end, wherein the power packet is a data packet containing current power information, indicating that information transmission is supported between the wireless charging receiving end and the wireless charging transmitting end.

[0115] In step S102, second response information sent by the wireless charging transmitter is received.

[0116] The second response information is the response of the wireless charging transmitter to the power packet.

[0117] In step S103, when the second response information carries the second power information of the wireless charging transmitter and the wireless charging receiver allows the wireless charging transmitter to adjust the power to the first target power, a third response information is sent to the wireless charging transmitter and the wireless charging receiver is adjusted to the second power mode.

[0118] The first target power is the power to be adjusted by the wireless charging transmitting end, and the second power mode of the wireless charging receiving end matches the first target power of the wireless charging transmitting end.

[0119] After the wireless charging receiving end receives the first target power sent by the wireless charging transmitting end, if the power adjusted by the wireless charging transmitting end is within the acceptable range of the wireless charging receiving end, the wireless charging transmitting end is allowed to make corresponding adjustments and send a third response message. At the same time, the wireless charging receiving end sends the first target power to the receiving end charging control module AP, and matches the corresponding second power mode according to the first target power.

[0120] In the embodiment of the present disclosure, the wireless charging receiving end receives the power adjustment information actively sent by the transmitting end, and can indicate whether to allow the transmitting end to adjust the power to the target power, and adjust the power mode of the wireless charging receiving end to match the wireless charging transmitting end. In addition, through the wireless charging method in the embodiment of the present disclosure, the charging control module of the receiving end can communicate with the wireless charging transmitting end and respond to the request of the transmitting end in a timely manner, thereby improving the charging efficiency.

[0122] In step S111, a power packet sent by a wireless charging receiving end is received.

[0123] The wireless charging transmitter receives the power packet sent by the wireless charging receiver, wherein the power packet is a data packet containing current power information.

[0124] In step S112, when the power packet carries the third power information and the wireless charging transmitter allows the wireless charging transmitter to be adjusted to the second target power, a fourth response message is sent to the wireless charging receiver, and the wireless charging transmitter is adjusted to the third power mode.

[0125] The fourth response information is used to indicate that the wireless charging transmitter allows power adjustment, and the third power mode of the wireless charging transmitter matches the second target power. For example, the third power mode can be the second target power or a power mode within a certain range from the second target power.

[0126] In the disclosed embodiment, the wireless charging transmitter receives the third power information actively sent by the receiver, and can indicate whether it is allowed to adjust the power to the target power, and adjust the corresponding power mode of the wireless charging transmitter. Reasonable power control can be achieved by the wireless charging receiver actively communicating with the transmitter about the power that needs to be adjusted. The wireless charging transmitter can adjust the corresponding power level according to the notification of the receiver to adapt to the requirements of the receiver. This active communication method can make the power adjustment of the wireless charging transmitter and receiver more reasonable, and can adapt to changes in different devices and charging environments.

[0127] Fig. 9 is a flow chart of a wireless charging method applied to a charging receiving end according to an exemplary embodiment. Fig. 9 As shown, the method includes steps S121 to S123.

[0128] In step S121, a power packet is sent to the wireless charging transmitter, wherein the power packet carries third power information, and the third power information is used to instruct the wireless charging transmitter to adjust the charging power to the second target power.

[0129] The wireless charging receiver actively communicates with the transmitter by sending power packets, instructing the transmitter to adjust the power.

[0130] In step S122, fourth response information sent by the wireless charging transmitter is received, wherein the fourth response information is a response of the wireless charging transmitter to the power packet.

[0131] After receiving the power packet sent by the wireless charging receiving end, the wireless charging transmitting end determines whether to adjust the charging power according to the third power information based on the current power information, and sends fourth response information to the receiving end.

[0132] In step S123, when the fourth response information indicates that the wireless charging transmitting end allows power adjustment, the wireless charging receiving end is adjusted to the fourth power mode.

[0133] After receiving the response information from the transmitter allowing the corresponding power adjustment, the wireless charging receiver adjusts its own power mode. The fourth power mode of the wireless charging receiver matches the target power.

[0134] In the disclosed embodiment, the wireless charging receiving end can actively communicate with the transmitting end to negotiate power adjustment to ensure the efficiency and safety of the charging process. By sending a power packet and receiving the fourth response information from the transmitting end, the receiving end can instruct the transmitting end to reasonably adjust the power according to its own situation, and clearly know whether it is necessary to adjust its own power level according to the power information of the transmitting end, avoiding unnecessary and unreasonable power adjustment that causes power mismatch between the transmitting end and the receiving end.
