[0179] It is understandable that the charging system described in the embodiment of the present disclosure is intended to more clearly illustrate the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0180] The following embodiments of the present disclosure may be applied to the charging system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The various entities shown in FIG1A are examples only. The charging system may include all or a portion of the entities shown in FIG1A , or may include entities other than those shown in FIG1A . The number and form of the entities may be arbitrary, and the entities may be physical or virtual. The connections between the entities are examples only. The entities may be connected or disconnected, and the connections may be in any manner, including direct or indirect, wired or wireless.

[0181] In some embodiments of the present disclosure, a Wireless Power Consortium (WPC) wireless charging receiver provides digital information to a wireless charging transmitter through AC load modulation, and the wireless charging transmitter then demodulates the corresponding communication information.

[0182] In some embodiments, the “wireless charging transmitter” may also be referred to as a “transmitter”, “power supply device”, “charger”, “wireless charger”, “TX”, etc.

[0183] In some embodiments, the “wireless charging receiving end” may also be referred to as the “receiving end”, “terminal device”, “device to be charged”, “RX”, etc.

[0184] In some embodiments, FIG1B is a schematic diagram illustrating a flow chart of a wireless charging system according to an embodiment of the present disclosure. As shown in FIG1B , in the wireless charging system, the power conversion module is used to transfer energy to the power receiving module (POWER), the receiving end can transmit information to the transmitting end through load modulation (ASK), and the transmitting end can transmit information to the receiving end through frequency modulation (FSK).

[0185] In some embodiments, the Qi wireless charging communication protocol defines the communication specifications of TX and RX handshakes, which are mainly based on the ping detection method.

[0186] In some embodiments, Figure 1C is a flow diagram illustrating a BPP protocol according to an embodiment of the present disclosure. As shown in Figure 1C, the Basic Power Profile (BPP) protocol includes four phases: Selection, Ping, Identification & Configuration, and Power Transfer.

[0187] In some embodiments, FIG1D is a schematic diagram of a signal according to an embodiment of the present disclosure. As shown in FIG1D , when TX sends ping energy (t ping The corresponding time period) is set by the protocol, RX needs to be within the time limit (t first The handshake is successful after both parties confirm the reply signal strength packet (corresponding time period).

[0188] In some embodiments, the fast-charging protocol of a terminal device is a proprietary protocol of its manufacturer. Different manufacturers' fast-charging protocols are not universal. When users charge their terminal devices, they must use a specific charger; otherwise, the charging power of the terminal device will be limited. Therefore, how to achieve compatibility of fast-charging protocols between different terminal devices has become an urgent problem to be solved.

[0189] FIG2A is an interactive schematic diagram of a charging method according to an embodiment of the present disclosure. The method can be performed by the above-mentioned charging system. As shown in FIG2A , the method may include:

[0190] Step S2101: The wireless charging receiving end determines that the wireless charging transmitting end cannot wirelessly charge the wireless charging receiving end based on the first charging protocol.

[0191] In some embodiments, the wireless charging transmitter may be a transmitter that establishes a wireless connection with the wireless charging receiver, and the wireless charging transmitter and the wireless charging receiver may implement charging control through the transmission of charging messages.

[0192] In some embodiments, “the wireless charging transmitter may be a transmitter that establishes a wireless connection with the wireless charging receiver” may be understood as “the wireless charging transmitter detects the wireless charging receiver.”

[0193] In some embodiments, the first charging protocol may be a wireless charging protocol that is supported by the first wireless charging receiving end corresponding to the first device identifier and is not supported by the second wireless charging receiving end corresponding to the second device identifier.

[0194] For example, the first charging protocol can only be used for a wireless charging receiving end whose device identifier is the first device identifier.

[0195] In some embodiments, the first device identifier is a device identifier corresponding to the wireless charging receiving end.

[0196] For example, the first charging protocol can only be used for a wireless charging receiving end and a first wireless charging receiving end having the same device identifier as the wireless charging receiving end.

[0197] In some embodiments, different device identifiers may correspond to different manufacturers.

[0198] For example, the first charging protocol can only be used for a wireless charging receiving end of one manufacturer, that is, the first charging protocol is a private charging protocol of a manufacturer.

[0199] In some embodiments, the first charging protocol is a proprietary fast charging protocol.

[0200] In some embodiments, the fast charging protocol may be a charging protocol that can support fast charging of a wireless charging receiving end.

[0201] In some embodiments, "fast charging" can be understood as "charging power greater than a first power threshold," for example, the first power threshold can be 18 W. It should be noted that the embodiments of the present disclosure do not limit the first power threshold.

[0202] In some embodiments, after the wireless charging receiver sends a signal strength packet, an authentication packet, and a configuration packet to the wireless charging transmitter, the wireless charging receiver determines whether to enter the BPP mode or the Extended Power Profile (EPP) mode based on the response information sent by the wireless charging transmitter. If the wireless charging receiver receives the response information (ACK) sent by the wireless charging transmitter, the wireless charging receiver may enter the EPP mode. If the wireless charging receiver does not receive the response information (ACK) sent by the wireless charging transmitter, the wireless charging receiver may enter the BPP mode.

[0203] In some embodiments, before the wireless charging receiving end enters the EPP mode or the BPP mode, it can perform a private handshake with the wireless charging transmitting end. If the private handshake is successful, it means that the wireless charging transmitting end can wirelessly charge the wireless charging receiving end based on the first charging protocol; if the private handshake fails, it means that the wireless charging transmitting end cannot wirelessly charge the wireless charging receiving end based on the first charging protocol.

[0204] It should be noted that the specific implementation process of the private handshake can refer to the relevant process of the existing technology and will not be repeated here.

[0205] In some embodiments, a successful private handshake may indicate that the device identifier of the wireless charging transmitter is the same as the device identifier of the wireless charging receiver, or may indicate that the wireless charging transmitter and the wireless charging receiver belong to the same manufacturer.

[0206] Step S2102: The wireless charging receiving end sends first information to the wireless charging transmitting end.

[0207] In some embodiments, the first information may be used to request identity authentication of the wireless charging receiving end.

[0208] In some embodiments, the first information may include identity information of the wireless charging receiving terminal.

[0209] In some embodiments, the first information may be a data packet including identity information of the wireless charging receiving terminal.

[0210] In some embodiments, the identity information may include at least one of the following:

[0211] Customer code;

[0212] Hardware version.

[0213] In some embodiments, the customer code may also be called a Customer Code, which may be used to indicate the manufacturer, and different manufacturers may correspond to different customer codes. For example, the customer code of manufacturer A may be 0x01, and the customer code of manufacturer B may be 0x03.

[0214] In some embodiments, the hardware version may also be referred to as Hardware Version, and may be used to indicate hardware version information. For example, the hardware version of a wireless charging receiver may be the hardware version information of the wireless charging receiver, and the hardware version of a wireless charging transmitter may be the hardware version information of the wireless charging transmitter.

[0215] In some embodiments, the format of the first information may be as shown in Table 1:

[0216] Table 1

[0217] Among them, Customer Code[0] indicates the customer code, Hardware Version[0] indicates the hardware version, and “0x??” indicates that the specific content is undefined.

[0218] It should be noted that the format of the first information shown in Table 1 is for illustration only, and the present disclosure does not limit the format of the first information.

[0219] In some embodiments, the first information may not include the identity information of the wireless charging receiving end. For example, the first information may be used to obtain the identity information of the wireless charging transmitting end.

[0220] In some embodiments, when the wireless charging receiving end determines that the wireless charging transmitting end cannot wirelessly charge the wireless charging receiving end based on the first charging protocol, the wireless charging receiving end may send the first information to the wireless charging transmitting end.

[0221] Step S2103: The wireless charging transmitting end sends second information to the wireless charging receiving end.

[0222] In some embodiments, the second information may be used to indicate identity information of the wireless charging transmitter.

[0224] In some embodiments, the first information may be a data packet including identity information of the wireless charging transmitter.

[0225] In some embodiments, the format corresponding to the second information may be the same as the format of the first information.

[0226] In some embodiments, the format corresponding to the second information may be different from the format of the first information.

[0227] It should be noted that the embodiment of the present disclosure does not limit the format corresponding to the second information.

[0228] In some embodiments, after the wireless charging transmitting end receives the first information sent by the wireless charging receiving end, the wireless charging transmitting end may send the second information to the wireless charging receiving end.

[0229] In some embodiments, the second information may also include a comparison result between the identity information of the wireless charging transmitter and the identity information of the wireless charging receiver. In this way, the amount of data transmitted by the wireless charging transmitter can be reduced, thereby improving charging efficiency.

[0230] For example, if the first information includes the identity information of the wireless charging receiving end, the wireless charging transmitting end may compare the identity information of the wireless charging receiving end with its own identity information based on the first information to obtain a comparison result.

[0231] In some embodiments, the comparison result may be the same or different. For example, 0x01 may be used to indicate the same, and 0x02 may be used to indicate the different.

[0232] Step S2104: The wireless charging receiving end determines, based on the second information, that the identity information of the wireless charging transmitting end matches the identity information of the wireless charging receiving end.

[0233] In some embodiments, after receiving the second information sent by the wireless charging transmitter, the wireless charging receiver can compare its own identity information with the identity information indicated by the second information to determine whether the identity information of the wireless charging transmitter matches the identity information of the wireless charging receiver.

[0234] In some embodiments, if the second information includes a comparison result between the identity information of the wireless charging transmitter and the identity information of the wireless charging receiver, it can be determined based on the comparison result whether the identity information of the wireless charging transmitter and the wireless charging receiver match. For example, if the comparison result is 0x01, it can be determined that the identity information of the wireless charging transmitter and the wireless charging receiver match; if the comparison result is 0x02, it can be determined that the identity information of the wireless charging transmitter and the wireless charging receiver do not match.

[0235] Step S2105: The wireless charging receiving end sends third information to the wireless charging transmitting end.

[0236] In some embodiments, the third information may be used to request encryption authentication of the wireless charging receiving end.

[0237] In some embodiments, the third information may include one or more random numbers. For example, the third information may include a, b, c, and d.

[0238] It should be noted that the embodiment of the present disclosure does not limit the specific content of the third information. For example, the third information may also be one or more character strings.

[0239] In some embodiments, the format corresponding to the third information is as shown in Table 2:

[0241] Among them, Random value[] represents a random number.

[0242] It should be noted that the format of the third information shown in Table 2 is for illustration only, and the present disclosure does not limit the format of the third information.

[0243] Step S2106: The wireless charging transmitting end encrypts the third information to obtain fourth information.

[0244] In some embodiments, the fourth information may be information obtained by encrypting the third information by the wireless charging transmitter.

[0245] In some embodiments, after receiving the third information sent by the wireless charging receiving end, the wireless charging transmitting end may encrypt the third information according to a specified encryption method to obtain the fourth information.

[0246] In some embodiments, the specified encryption method may be one-way encryption, symmetric encryption, or asymmetric encryption. The embodiments of the present disclosure do not limit the specified encryption method.

[0247] For example, if the designated encryption method is one-way encryption, the wireless charging transmitter can calculate the fourth information based on the third information using a designated calculation formula. For example, the designated calculation formula can be a*5+b / 6+9-7.

[0248] It should be noted that the embodiments of the present disclosure do not limit the specified calculation formula.

[0249] For example, if the designated encryption method is symmetric encryption, the wireless charging transmitter may add a key to the third information using SHA1 or other algorithms in the prior art to obtain the fourth information.

[0250] In some embodiments, the format corresponding to the fourth information is as shown in Table 3:

[0251] Table 3

[0252] Among them, TX result[] represents the data obtained after encrypting the random number.

[0253] It should be noted that the format of the fourth information shown in Table 3 is for illustration only, and the present disclosure does not limit the format of the fourth information.

[0254] Step S2107: The wireless charging transmitting end sends fourth information to the wireless charging receiving end.

[0255] In some embodiments, after obtaining the fourth information, the wireless charging transmitting end may send the fourth information to the wireless charging receiving end.

[0256] Step S2108: The wireless charging receiving end determines, based on the fourth information, that the encryption information of the wireless charging transmitting end matches the encryption information of the wireless charging receiving end.

[0257] In some embodiments, the wireless charging receiving end may encrypt the third information according to a specified encryption method to obtain encrypted information, and determine whether the encrypted information of the wireless charging transmitting end and the wireless charging receiving end matches by comparing the encrypted information with the fourth information. For example, if it is determined that the encrypted information and the fourth information are the same, then it is determined that the encrypted information of the wireless charging transmitting end and the wireless charging receiving end matches; if it is determined that the encrypted information and the fourth information are different, then it is determined that the encrypted information of the wireless charging transmitting end and the wireless charging receiving end does not match.

[0258] In some embodiments, the wireless charging receiving end may also decrypt the fourth information according to a specified decryption method to obtain decrypted information, and determine whether the encrypted information of the wireless charging transmitting end and the wireless charging receiving end matches by comparing the decrypted information with the third information. For example, if it is determined that the decrypted information and the third information are the same, then it is determined that the encrypted information of the wireless charging transmitting end and the wireless charging receiving end matches; if it is determined that the decrypted information and the third information are different, then it is determined that the encrypted information of the wireless charging transmitting end and the wireless charging receiving end does not match.

[0259] Step S2109: The wireless charging receiving end sends fifth information to the wireless charging transmitting end.

[0671] Step S5101: The wireless charging receiving end determines that the wireless charging transmitting end cannot wirelessly charge the wireless charging receiving end based on the first charging protocol.

[0672] The optional implementation of step S5101 can be found in step S2101 of FIG. 2A , the optional implementation of step S3101 of FIG. 3A , and other related parts in the embodiments involved in FIG. 2A and FIG. 3A , which will not be described in detail here.

[0673] Step S5102: The wireless charging receiving end determines that the wireless charging transmitting end can wirelessly charge the wireless charging receiving end based on the second charging protocol.

[0674] The optional implementation of step S5102 can refer to the optional implementation of step S2203 in Figure 2B and other related parts in the embodiment involved in Figure 2B, which will not be repeated here.

[0675] Step S5103: The wireless charging transmitter performs wireless charging on the wireless charging receiver based on the second charging protocol.

[0676] The optional implementation of step S5103 can refer to the optional implementation of step S4401 in Figure 4D and other related parts in the embodiment involved in Figure 4D, which will not be repeated here.

[0677] In some embodiments, the above method may include the method described in the above embodiments of the wireless charging receiving end, wireless charging transmitting end, charging device, charging system, etc., which will not be repeated here.

[0678] In some embodiments, FIG6A is a flow chart of a charging method according to an embodiment of the present disclosure. As shown in FIG6A , a mobile phone is used as an example for explanation. In FIG6A , CPP represents the process corresponding to the second charging protocol. The first part represents the process of entering the CPP from BPP. Before entering the CPP from BPP, the private protocol handshake of the mobile phone manufacturer will be performed first. If the handshake is successful, it means that TX and the mobile phone are from the same manufacturer and private fast charging is performed. If the handshake fails, private fast charging cannot be performed and the CPP handshake process can be executed. The second part represents the process of entering the CPP from EPP. When the mobile phone supports EPP, the CPP process can be entered from EPP. The specific process is similar to entering the CPP from BPP and will not be repeated here.

[0679] In some embodiments, the specific CPP process may include a lot of private content, and the corresponding links can be selected according to actual needs. Figure 6B is a schematic diagram of a CPP process according to an embodiment of the present disclosure. As shown in Figure 6B, the data packets involved in the CPP process include identity authentication (ID authentication), device authentication request (Device authentication Request), get adapter type (Get adaptor type), get TX type (Get TX uuid), set TX minimum operating frequency (Set TX min Frequencty), set TX maximum operating voltage (Set TX max Voltage Packet), set VIN data packet (Set VIN Packet), and set TX fan speed (Set TX FAN speed).

[0680] In some embodiments, ID authentication is a data packet used for authentication between TX and RX, containing two pieces of information: Customer Code and Hardware Version, used to exchange manufacturer information and version information between RX and TX. Figure 6C is a schematic diagram of information exchange according to an embodiment of the present disclosure. As shown in Figure 6C, RX can send an ID authentication request packet to TX, and TX can reply to RX with an ID authentication confirm packet.

[0681] The format of the information sent by RX to TX is shown in Table 1. The Customer Code sent by RX represents the phone manufacturer's information and can be used to distinguish products from different phone manufacturers. The Hardware Version represents the phone's hardware version and can be filled in based on the actual version.

[0682] The Customer Code returned by the TX represents the TX manufacturer's information and is used to distinguish TX products from different manufacturers. The format of the information is shown in Table 1. The Hardware Version represents the corresponding hardware version information of the TX and can be filled in according to actual needs.

[0683] In some embodiments, the device authentication phase can perform encryption authentication on both the TX and RX sides. There are several possible schemes for encryption authentication:

[0684] (1) One-way encryption

[0685] The RX sends one or more random numbers to the TX, for example, a, b, c, d...

[0686] Both the RX and TX sides have a common calculation formula, using the above random number calculation formula, for example: a*5+b÷6+9-7. After receiving the above random number, the TX side performs calculations and then returns the result to the RX. The RX itself will also use the same formula to calculate and compare the calculated result with the one sent by TX. If the comparison passes, it is considered that the encryption is passed and the subsequent process will continue.

[0687] (2) Symmetric encryption

[0688] Encryption can be performed using SHA 1 or other algorithms. The RX end sends a certain number of random numbers, which the TX end receives and calculates by adding a secret key. The calculated result is sent back to the RX end via FSK. The RX end also stores the corresponding secret key and calculates the random number. The calculated result is compared with the result returned by TX. After verification, the subsequent process continues.

[0689] The packet format sent by the RX end is shown in Table 2. After receiving the random number, the TX end performs calculations and sends the calculation results back to the RX. The data packet format is shown in Table 3.

[0691] In some embodiments, the Get adapter type packet is primarily used to obtain the adapter type at the TX end so that the RX end can determine the charging power. The RX end obtains the adapter type connected to the TX end to identify the maximum output power.

[0692] The data packet format sent by the RX is shown in Table 4. The TX end can reply with the corresponding adapter type. The reply packet format is shown in Table 5.
