in step 301, the electronic device sends an identification acquisition request to the charging device based on the load modulation function.

The electronic device may be a mobile phone, a tablet computer, a personal computer, etc. The charging device may be a wireless charging board, a wireless charger, or the like having a wireless charging function.

The load modulation function refers to a function of transmitting information based on a modulated signal, and in one possible implementation, the function may include in a specific implementation: the electronic equipment acquires a data packet, modulates the data packet to obtain a modulation signal, sends the modulation signal to the charging equipment, receives the modulation signal, demodulates the modulation signal to obtain the data packet, and executes the operation indicated in the data packet according to the data packet.

In one possible implementation, the communication mode of the load modulation function may be an FSK (Frequency-shift modulation) communication mode, an ASK (Amplitude-shift keying) communication mode, or other communication modes.

The data packet may carry charging configuration information of the electronic device, device identifier of the electronic device, or other types of information.

When charging is performed between the electronic device and the charging device based on the load modulation function, the electronic device sends an identification acquisition request to the charging device based on the load modulation function, wherein the identification acquisition request is a request for indicating to acquire the device identification of the charging device.

The device identifier of the charging device may be a MAC (Media Access Control ) address, an IP (Internet Protocol, internet protocol) address, a device name, a device account number, or the like of the charging device.

In one possible implementation, this step 301 may include: the electronic equipment acquires a second data packet comprising the identification acquisition request, modulates the second data packet to obtain a first modulation signal, and sends the first modulation signal to the charging equipment.

Wherein the first modulation signal is a signal representing the second data packet, since the first modulation signal is modulated according to the second data packet. When the charging equipment analyzes the first modulation signal, a second data packet corresponding to the first modulation signal can be obtained.

Optionally, the second data packet in the electronic device is stored in a memory of the electronic device or in a memory of the electronic device.

In step 302, the charging device receives an identification acquisition request based on the load modulation function, and returns a first device identification of the charging device to the electronic device according to the identification acquisition request.

The charging equipment can receive an identifier acquisition request sent by the electronic equipment based on the load modulation function, acquire a first equipment identifier of the charging equipment according to the identifier acquisition request, and return the first equipment identifier to the electronic equipment.

In one possible implementation manner, after the electronic device sends the first modulation signal to the charging device, the charging device receives the first modulation signal, demodulates the first modulation signal to obtain a second data packet, obtains a third data packet containing the first device identifier of the charging device based on an identifier obtaining request contained in the second data packet, modulates the third data packet to obtain a second modulation signal, and the charging device can send the second modulation signal to the electronic device.

Since the second modulated signal is used to represent the first device identification of the charging device, the charging device sends the second modulated signal to the electronic device, i.e. the charging device returns the first device identification to the electronic device.

And the electronic equipment and the charging equipment are communicated based on magnetic field coupling of a load modulation function, when the magnetic field generated by the electronic equipment and the magnetic field generated by the charging equipment are coupled, the charging equipment can send a modulation signal to the electronic equipment according to the coupled magnetic field, and at the moment, the charging equipment does not need to determine the electronic equipment according to equipment identification of the electronic equipment, and then sends the modulation signal to the electronic equipment.

In step 303, the electronic device receives a first device identification sent by the charging device based on the load modulation function.

The charging device sends a second modulation signal to the electronic device based on the load modulation function, and the electronic device can receive the first device identifier sent by the charging device based on the load modulation function. And the subsequent electronic equipment can establish close-range communication connection with the charging equipment according to the first equipment identifier.

In one possible implementation manner, the charging device sends the second modulation signal to the electronic device, and the electronic device receives the second modulation signal and demodulates the second modulation signal to obtain a third data packet indicated by the second modulation signal, that is, may obtain the first device identifier in the third data packet.

It should be noted that, in the embodiment of the present disclosure, steps 301 to 303 of the electronic device obtaining the first device identifier of the charging device through the load modulation function are optional steps. Because the load modulation function communicates in a magnetic field coupling mode, when the magnetic fields of the electronic equipment and the charging equipment are coupled, the equipment identification can be transmitted by utilizing the load modulation function, and the convenience of transmitting the equipment identification is improved. In another embodiment, steps 301-303 may be replaced with the following steps 3011-3013:

3011. the electronic device broadcasts a wireless signal.

The wireless signal is used for indicating other devices to send device identifiers to the electronic device, and the wireless signal carries a second device identifier of the electronic device. The second device identifier is used for indicating the electronic device, and other devices can send data to the electronic device according to the second device identifier. The second device identification of the electronic device may be a MAC (Media Access Control ) address, IP (Internet Protocol, internet protocol) address, device name, device account number, etc. of the electronic device.

3012. And when the charging equipment receives the wireless signal, the first equipment identification of the charging equipment is sent to the electronic equipment according to the second equipment identification.

When the charging equipment receives the wireless signal, the wireless signal is analyzed, a second equipment identifier in the wireless signal can be obtained, and the charging equipment can also obtain a first equipment identifier of the charging equipment according to the wireless signal and send the first equipment identifier to the electronic equipment.

In one possible implementation manner, after the charging device acquires the first device identifier, the first device identifier is carried in the return request, and the destination address of the return request is the first device identifier, so that the return request can be sent to the electronic device.

3013. The electronic equipment receives a first equipment identifier sent by the charging equipment.

In one possible implementation manner, when the electronic device receives the first device identifiers sent by the plurality of charging devices, the electronic device displays the received first device identifiers of the plurality of charging devices in a display interface, and then when the electronic device detects a triggering operation on any one of the first device identifiers, a close-range communication connection between the electronic device and the charging device indicated by the first device identifier is established according to the first device identifier.

The triggering operation may be a single click operation, a double click operation, a long press operation, or other operations.

In the embodiment of the disclosure, the electronic device can acquire the first device identifier of the charging device by broadcasting the wireless signal, establish the close-range communication connection with the charging device according to the received first device identifier, and the subsequent electronic device can perform wireless charging based on the close-range communication connection, so that the stability of wireless charging is improved.

In step 304, the electronic device establishes a close range communication connection with the charging device based on the first device identification.

After receiving the first equipment identifier sent by the charging equipment, the electronic equipment can send a connection establishment request to the charging equipment according to the first equipment identifier, after receiving the connection establishment request, the charging equipment sends a confirmation response to the electronic equipment according to the connection establishment request, and after receiving the confirmation response, the electronic equipment can establish close-range communication connection with the charging equipment, namely connection pairing between the electronic equipment and the charging equipment is achieved.

In one possible implementation, the close range communication connection established between the electronic device and the charging device is a bluetooth connection, or the close range communication connection established between the electronic device and the charging device is a WiFi communication connection, or the close range communication connection established between the electronic device and the charging device is an NFC communication connection.

It should be noted that, the embodiments of the present disclosure only take the charging device to return the first device identifier of the charging device to the electronic device as an example. In another embodiment, after the electronic device sends the identifier acquisition request or the wireless signal to the charging device, because the charging device does not have the short-range communication function, the charging device does not return the first device identifier to the electronic device based on the identifier acquisition request after the charging device receives the identifier acquisition request sent by the electronic device, and the electronic device does not establish the short-range communication connection with the charging device when the electronic device does not receive the first device identifier returned by the charging device within the first preset duration, and directly performs wireless charging based on the load modulation function.

The first preset duration may be set by the electronic device or set by a developer. The preset duration may be 3 seconds, 4 seconds, 5 seconds, or other values.

In step 305, the electronic device sends a data packet including charging configuration information to the charging device through the short-range communication connection.

After the electronic device establishes the close-range communication connection with the charging device, the electronic device can acquire a first data packet comprising charging configuration information, and the first data packet is sent to the charging device through the close-range communication connection.

The charging configuration information may be charging power of the electronic device during charging, charging power to be adjusted during charging of the electronic device, charging power received by the electronic device, and the like.

In one possible implementation, the data packet is a CEP (Control Error packet, control error data packet) when the charging configuration information is the charging power that needs to be adjusted when charging the electronic device. Alternatively, when the charging configuration information is the charging power received by the electronic device, the data packet is an RPP (Receiver Power Packet ).

The CEP is used to indicate the charging power that the charging device needs to adjust each time during charging. The RPP is used to indicate the charging power received by the electronic device during the charging process. When the charging equipment receives the RPP, whether the surrounding of the electronic equipment has metal foreign matters can be determined according to the charging power of the electronic equipment in the RPP and the charging power provided by the charging equipment.

When the charging device provides the charging current for the electronic device, if the metal foreign matter exists around the electronic device, the metal foreign matter can absorb a part of the charging current provided by the charging device to the electronic device, the charging power of the electronic device can be reduced, at the moment, the charging device can determine whether the metal foreign matter exists around the electronic device according to the received RPP, and when the metal foreign matter exists around the electronic device, the charging device can reduce the charging power or adjust the charging power to 0. When no metal foreign matter exists around the electronic equipment, the charging equipment continues to charge the electronic equipment.

In one possible implementation manner, the charging device obtains a difference value of the charging power according to the provided charging power and the received charging power of the electronic device, when the difference value is greater than a preset threshold value, the situation that metal foreign matters exist around the electronic device is indicated, and when the difference value is less than the preset threshold value, the situation that metal foreign matters do not exist around the electronic device is indicated.

Wherein the preset threshold may be determined by the charging device or by a developer.

It should be noted that, during the charging process, the electronic device will send a data packet through the close range communication connection every second preset time period.

The second preset duration may be set by the electronic device or by a developer. The second preset time period may be 20 milliseconds, 50 milliseconds, or other value.

In one possible implementation, the electronic device sends the RPP to the charging device once every a first preset duration and sends the CEP to the charging device once every a second preset duration over the established close range communication connection.

The first preset duration and the second preset duration may be the same or different.

And when the first preset time length is the same as the second preset time length, namely the electronic equipment simultaneously sends CEP and RPP to the charging equipment.

When the first preset duration and the second preset duration are different, the CEP is used for indicating the adjusted charging power in the charging process, the RPP is used for detecting whether metal foreign matters exist, and the period for detecting the metal foreign matters is not required to be too small, so that the first preset duration is adjusted to be smaller than the second preset duration, the stability of wireless charging can be ensured, and the transmitted data size can be reduced.

In step 306, the charging device provides a charging current to the electronic device according to the charging configuration information.

After receiving a first data packet including charging configuration information sent by the electronic device, the charging device adjusts the provided charging current according to the charging configuration information, and provides the adjusted charging current for the electronic device.

In step 307, the electronic device is charged based on the charging current provided by the charging device.

The electronic equipment obtains the charging current provided by the charging equipment, and the charging can be performed based on the charging current.

In one possible implementation, when the charging of the electronic device is completed, the electronic device may send a charging completion instruction to the charging device based on the established close range communication connection, and when the charging device receives the charging completion instruction, no charging current is provided to the electronic device.

In another possible implementation, when the charging of the electronic device is completed, the electronic device disconnects the established close range communication connection, i.e. disconnects the wireless charging between the electronic device and the charging device, and the electronic device does not perform the wireless charging any more.

It should be noted that, in the embodiment of the present disclosure, when the close range communication connection is established, the load modulation function is turned off, that is, the electronic device performs wireless charging only by adopting the close range communication connection mode, and does not perform wireless charging by adopting the load modulation function. Or when the short-range communication connection is detected to be disconnected, the electronic equipment cannot be wirelessly charged with the charging equipment through the short-range communication connection, and the load modulation function is started at the moment, so that the wireless charging is performed based on the load modulation function.
