It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present disclosure, the information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first information may also be referred to as second information, and similarly, the second information may also be referred to as first information. Depending on the context, the word "if" as used herein can be interpreted as "when" or "when" or "in response to determination".

The execution subjects involved in the embodiments of the present disclosure include, but are not limited to: a wireless charging transmitter, such as a wireless charging base, and a wireless charging receiver, such as a mobile phone.

An application scenario of the embodiments of the present disclosure is that, as shown in FIG. 1, the charging coil of the wireless charging transmitting end generates electromagnetic induction through Faraday's law to transfer energy to the charging coil of the wireless charging receiving end. The wireless charging transmitter and the wireless charging receiver use the same frequency beam as the wireless charging beam as the carrier, or directly use the charging beam as the carrier for in-band communication. In this way, the in-band communication will interfere with the wireless charging beam and reduce the charging efficiency.

As shown in FIG. 2, this exemplary embodiment provides a wireless charging authentication method. The wireless charging authentication method may be applied to the wireless charging receiving end, and the wireless charging authentication method may include:

Step 201: Receive instruction information;

Step 202: In response to determining that the wireless charging transmitter supports out-of-band communication according to the instruction information, perform wireless charging authentication based on the out-of-band communication.

Here, the wireless charging receiving end may be a power receiving device that supports the Qi wireless charging standard, for example, a mobile phone that supports wireless charging. The wireless charging transmitter may be a power supply device that indicates the Qi wireless charging standard, for example, a charger that supports wireless charging. Of course, this embodiment is not limited to the Qi wireless charging standard, and it can also be adapted to power receiving devices supporting other standards in the evolution of the standard.

In-band communication may be communication in which the carrier and the charging beam have the same frequency band, or the charging beam is directly used as the carrier for signal transmission. For example, in-band communication can load information on the charging beam by means of amplitude modulation or frequency shift keying modulation, and perform signal transmission through the charging coil of the wireless charging transmitting end and the charging coil of the wireless charging receiving end.

Out-of-band communication may be a communication that uses a carrier wave different from the frequency band of the charging beam for signal transmission. For example: Out-of-band communication can be Bluetooth, near field communication, WiFi, etc. Here, Bluetooth may include Bluetooth Low Energy and so on. Since the carrier of in-band communication has the same frequency band as the charging beam, it will interfere with the charging beam and reduce the charging efficiency; or, because the charging beam is loaded with a modulated signal, the stability of the wireless charging voltage is reduced, and the charging efficiency is reduced .

Here, the authentication of wireless charging refers to the process of mutual authentication between the wireless charging transmitter and the wireless charging receiver based on the Qi wireless charging standard. Through the authentication of wireless charging, the wireless charging transmitter can determine whether the wireless charging receiver is a power receiving device that meets the requirements of wireless charging, and the wireless charging protocol that can be used by the wireless charging receiver. Here, the wireless charging protocol may include a basic power profile (BPP, Basic Power Profile) protocol and an extended power profile (EPP, Extended Power Profile) protocol, etc.

The wireless charging transmitter can send instructions after establishing a communication connection with the wireless charging receiver. The wireless charging transmitter can send instruction information during the initialization process after the communication connection is established. Here, the communication connection may be a communication connection established through in-band communication, or may be a communication connection established through out-of-band communication.

The wireless charging transmitter can send instruction information when the wireless charging receiver is close to the wireless charging transmitter. When the wireless charging receiving terminal is close to the wireless charging transmitting terminal, the load of the charging coil of the wireless charging transmitting terminal will transmit changes. Therefore, the wireless charging transmitting terminal can determine whether the wireless charging transmitting terminal is close according to the load condition of the charging coil.

The indication information may include an indication of whether the wireless charging transmitter supports out-of-band communication. Here, whether the wireless charging transmitter supports out-of-band communication may include: whether the wireless charging transmitter supports out-of-band communication of wireless charging, and/or whether the wireless charging transmitter supports out-of-band communication of wireless charging authentication.

Exemplarily, the support information can use 1 bit to indicate whether the wireless charging transmitter supports out-of-band communication. For example, "1" can be used to indicate support, and "0" can be used to indicate unsupported; or "0" can be used to indicate support. Use "1" to indicate that it is not supported.

When the charging coil is used for charging, the charging coil of the wireless charging transmitting end and the charging coil of the wireless charging receiving end generate electromagnetic induction to transfer energy through Faraday's law. When the charging coil is used for in-band communication, the charging coil of the wireless charging transmitter and the charging coil of the wireless charging receiver are used as communication antennas to send or receive modulated electromagnetic signals. In-band communication due to the multiplexing of the charging coil with wireless charging, on the one hand, limited by the charging coil, the use of amplitude modulation or frequency shift keying modulation for in-band communication has poor anti-interference and low transmission rate; on the other hand, the use of band Intracommunication will affect the efficiency of wireless charging when communicating; and then affect the user experience.

The wireless charging receiver can determine whether the wireless charging transmitter supports out-of-band communication based on the support information; when the wireless charging transmitter supports out-of-band communication, it can select out-of-band communication for wireless charging authentication.

In this way, the wireless charging transmitter can indicate whether to support out-of-band communication through the instruction information. When the wireless charging transmitter supports out-of-band communication, the wireless charging receiver can select out-of-band communication for wireless charging authentication according to the instructions. The communication delay improves the user experience; on the other hand, the authentication of wireless charging and wireless charging adopt different communication methods, and wireless charging is not affected by the authentication of wireless charging, which improves the efficiency of wireless charging.

In one embodiment, step 202 may include:

In response to determining according to the instruction information that the wireless charging transmitter supports out-of-band communication, and the wireless charging receiver supports the same type of out-of-band communication, the wireless charging is authenticated through out-of-band communication supported by both the wireless charging transmitter and the wireless charging receiver. right.

The indication information may include an indication of the type of out-of-band communication supported by the wireless charging transmitter.

The indication information can use 1 bit to indicate the type of out-of-band communication supported, for example: "1" can be used to indicate that the supported out-of-band communication is Bluetooth, and "0" can be used to indicate that the supported out-of-band communication is a near field communication connection; The information can also use two bits to indicate the type of out-of-band communication supported. You can use "00" to indicate that the supported out-of-band communication is Bluetooth; use "01" to indicate that the supported out-of-band communication is to support near field communication, and use "10" "Indicates that the supported out-of-band communication is WiFi connection.

When the wireless charging receiving end determines that the wireless charging transmitting end supports out-of-band communication, and the wireless charging receiving end and the wireless charging transmitting end currently use the same type of out-of-band communication, then the wireless charging receiving end uses the first type of communication connection to initiate and The wireless charging transmitter initiates the authentication of wireless charging.

When the wireless charging receiving end and the wireless charging transmitting end support multiple out-of-band communications at the same time, the wireless charging receiving end can select one of the out-of-band communications to perform wireless charging authentication based on a preset selection rule. For example, you can select the currently connected out-of-band communication for wireless charging authentication, or you can select the out-of-band communication with the fastest transmission speed for wireless charging authentication, or you can select the easiest out-of-band connection method Communication for authentication of wireless charging. In this way, the indication information explicitly indicates the type of out-of-band communication supported by the wireless charging transmitter, and the wireless charging receiver can determine the out-of-band communication used for wireless charging authentication according to the type of out-of-band communication supported by the wireless charging transmitter.

In an embodiment, the wireless charging authentication method may include:

When the instruction information indicates that the wireless charging transmitter does not support the out-of-band communication supported by the wireless charging receiver, the wireless charging receiver cannot authenticate the wireless charging with the wireless charging transmitter through out-of-band communication. The wireless charging receiver can establish in-band communication with the wireless charging transmitter through the charging coil. Authentication of wireless charging through in-band communication. In this way, the authentication of wireless charging can be ensured, and the wireless charging can be completed.

In one embodiment, step 202 may include: the wireless charging transmitter does not support out-of-band communication of wireless charging; or, the wireless charging out-of-band communication supported by the wireless charging transmitter is different from the out-of-band communication supported by the wireless charging receiver. .

Here, when the wireless charging transmitter does not support out-of-band communication, or the wireless charging out-of-band communication supported by the wireless charging transmitter is different from the out-of-band communication supported by the wireless charging receiver, the wireless charging receiver can be established through the charging coil In-band communication with the wireless charging transmitter. Authentication of wireless charging through in-band communication. In this way, the authentication of wireless charging can be ensured, and the wireless charging can be completed.

In an embodiment, step 202 may include: in response to determining the charging protocol supported by the wireless charging transmitter according to the instruction information, performing authentication of the charging protocol through out-of-band communication.

Here, the indication information sent by the wireless charging transmitter may also carry an indication of the charging protocol supported by the wireless charging transmitter. Here, the charging protocol may include BPP, EPP, and so on. BPP is a 5W wireless charging standard, and EPP is a wireless charging standard up to 15W. The wireless charging receiver determines the charging protocol supported by the wireless charging transmitter according to the instruction information, and selects the available charging protocol according to the charging protocol supported by the wireless charging receiver itself, and performs wireless charging authentication for the available charging protocol.

Exemplarily, the indication information indicates that the wireless charging transmitter supports EPP. The wireless charging receiver itself supports two wireless charging standards, BFF and EPP. Therefore, the wireless charging receiver can initiate wireless charging authentication based on EPP.

In one embodiment, step 202 may include: in response to determining according to the instruction information that the wireless charging terminal supports the private charging protocol and at least one standard charging protocol, performing the authentication of the private charging protocol through out-of-band communication;

In response to the failure of the authentication of the private charging protocol, the authentication of the standard charging protocol is performed through out-of-band communication.

Here, the private charging protocol is a charging protocol jointly formulated by one merchant or multiple merchants, but it has not been confirmed as a charging standard protocol by the industry or the sovereign body for the time being. The standard charging protocol is an agreement recognized as a charging standard by the industry or a sovereign body. Generally, the private charging protocol can be a wireless charging protocol customized by the equipment manufacturer and having different charging efficiency from the standard charging protocol. For example, a private charging protocol can have a higher charging power than a standard charging protocol, and wireless charging is more efficient. The standard charging protocol may be a Qi standard wireless charging protocol or the like. The private charging protocol can be different from the standard charging protocol. The private charging protocol can be completely independent from the standard charging protocol. The private charging protocol can be a wireless charging protocol with higher charging efficiency than BPP or EPP.

The indication information may indicate the first charging protocol and the second charging protocol at the same time, and the charging efficiency of the first charging protocol is higher than the charging efficiency of the second charging protocol. The wireless charging receiver can first authenticate the first charging protocol with high charging efficiency, and then authenticate the second charging protocol with low charging efficiency. The first charging protocol is preferentially used for wireless charging. When the wireless charging receiver does not support the first charging protocol, the second charging protocol can be authenticated. Here, the first charging protocol may include a private charging protocol, and the second charging protocol may include a standard charging protocol.

Equipment manufacturers can customize the wireless charging components of the wireless charging transmitter and wireless charging receiver so that the charging power of the wireless charging transmitter and wireless charging receiver is greater than BPP or EPP, and they can communicate and authenticate each other in a way different from the standard charging protocol.

When the indication information indicates that the wireless charging terminal supports the private charging protocol and at least one standard charging protocol, if the wireless charging receiving terminal also supports the private charging protocol, the private charging protocol may be prioritized for wireless charging.

When the authentication of the private charging protocol cannot be completed, that is, the private charging protocol cannot be used for wireless charging, the wireless charging authentication of the standard wireless charging protocol can be performed, and then the standard wireless charging protocol can be used for charging.

In response to the successful authentication of the private charging protocol, the authentication of the standard wireless charging is stopped. When the wireless charging transmitter and the wireless charging receiver have completed the authentication of the private charging protocol, the wireless charging authentication of the standard charging protocol is no longer performed.

In this way, a private charging protocol with higher charging power can be selected for charging, which improves charging efficiency. And it can reduce the chance of directly selecting a standard charging protocol with lower charging efficiency for wireless charging. Here, the authentication of the private charging protocol may be the authentication of the private charging protocol and the like.

As shown in FIG. 3, this exemplary embodiment provides a wireless charging authentication method. The wireless charging authentication method may be applied to a wireless charging transmitter. The wireless charging authentication method may include:

Step 301: Send instruction information; where the instruction information is used for the wireless charging receiving end to determine whether the wireless charging transmitting end supports out-of-band communication;

Step 302: Perform wireless charging authentication based on out-of-band communication and the wireless charging receiving end.

In-band communication may be communication in which the carrier and the charging beam have the same frequency band, or the charging beam is directly used as the carrier for signal transmission. For example, in-band communication can use amplitude modulation or frequency shift keying modulation to load information on the charging beam and transmit signals through the charging coil of the wireless charging transmitter and the wireless charging receiver.

The wireless charging transmitter can send instruction information after establishing a communication connection with the wireless charging receiver. The wireless charging transmitter can send instruction information during the initialization process after the communication connection is established. Here, the communication connection may be a communication connection established through in-band communication, or may be a communication connection established through out-of-band communication.

In an embodiment, the instruction information is also used for the wireless charging receiving end to determine the type of out-of-band communication supported by the wireless charging transmitting end;

Step 302 may include: in response to the wireless charging transmitter and the wireless charging receiver both supporting the same type of out-of-band communication, performing wireless charging authentication based on the out-of-band communication supported by both the wire charging transmitter and the wireless charging receiver.

When the wireless charging receiving end and the wireless charging transmitting end support multiple out-of-band communications at the same time, the wireless charging receiving end can select one of the out-of-band communications to perform wireless charging authentication based on a preset selection rule. For example, you can select the currently connected out-of-band communication for wireless charging authentication, or you can select the out-of-band communication with the fastest transmission speed for wireless charging authentication, or you can select the easiest out-of-band connection method Communication for authentication of wireless charging.

In this way, the indication information explicitly indicates the type of out-of-band communication supported by the wireless charging transmitter, and the wireless charging receiver can determine the out-of-band communication used for wireless charging authentication according to the type of out-of-band communication supported by the wireless charging transmitter.

In an embodiment, the wireless charging authentication method may include:

In one embodiment, the wireless charging transmitter does not support out-of-band communication supported by the wireless charging receiver, including: the wireless charging transmitter does not support out-of-band communication for wireless charging; or, the wireless charging transmitter supports out-of-band communication.

Here, the charging protocol may include BPP, EPP, and so on. BPP is a 5W wireless charging standard, and EPP is a wireless charging standard up to 15W.

The wireless charging receiver determines the charging protocol supported by the wireless charging transmitter according to the instruction information, and selects the available charging protocol according to the charging protocol supported by the wireless charging receiver itself, and performs wireless charging authentication for the available charging protocol.

Step 302 may include: authenticating the private charging protocol with the wireless charging receiver through out-of-band communication;

In response to the failure of the authentication of the private charging protocol, the standard charging protocol is authenticated with the wireless charging receiver through out-of-band communication.

When the authentication of the private charging protocol cannot be completed, that is, when the private charging protocol cannot be used for wireless charging, the standard wireless charging protocol can be authenticated for wireless charging, and then the standard wireless charging protocol can be used for charging.

In response to the successful authentication of the private charging protocol, the authentication of the standard wireless charging is stopped. When the wireless charging transmitter and the wireless charging receiver have completed the authentication of the private charging protocol, the wireless charging authentication of the standard charging protocol is no longer performed. In this way, a protocol with a higher charging power can be selected for charging, and the charging efficiency can be improved. Here, the authentication of the private charging protocol may be the authentication of the private charging protocol and the like.

A specific example is provided below in conjunction with any of the foregoing embodiments:

The mobile phone with Bluetooth Low Energy (BLE, Bluetooth Low Energy) out-of-band communication function and the wireless charger first pass Bluetooth authentication. The mobile phone obtains the first information sent by the wireless charger, where the first information is used to indicate whether the wireless charger supports out-of-band communication, and the type of out-of-band communication supported. Among them, the type of out-of-band communication supported can be 1 The bits indicates two types of out-of-band communication. The mobile phone judges whether the wireless charger supports BLE. Here, the mobile phone is the wireless charging receiver (Rx), and the wireless charger is the wireless charging transmitter (Tx).

Similarly, mobile phones and wireless chargers can also be authenticated through near field communication.

If the wireless charger supports out-of-band communication, the mobile phone initiates authentication based on Bluetooth Low Energy (BLE).

If the wireless charger does not support out-of-band communication, the mobile phone initiates authentication for in-band communication.

The first information can also be used to indicate both in-band communication authentication and out-of-band communication authentication information. For example, the first information can contain both the out-of-band communication type and the wireless charging protocol, such as the EPP type, so that multiple times can be reduced. Generate information and improve efficiency.

It also allows the BLE-based private protocol to start before the EPP authentication, that is, the private protocol takes precedence; the private protocol and the standard authentication process are relatively independent and do not affect each other.
