Technical Field

Background

Wireless Power Transmission (WPT) is a technology that realizes Power Transmission by using a non-physical contact method. The technical principle of wireless power transmission comprises the following steps: electromagnetic induction principle, microwave energy transmission principle and electromagnetic field resonance principle. Taking WPT using the principle of electromagnetic induction as an example, a wireless charging device includes a transmitting coil, and an electronic device (e.g., a mobile phone, an electronic watch, etc.) that receives wireless electric energy includes a receiving coil. The transmitting coil of the wireless charging device is connected with an alternating current power supply, so that an alternating magnetic field is generated in the transmitting coil. When the electronic device approaches the wireless charging device, the alternating magnetic field of the transmitting coil causes the receiving coil to generate an induced current, thereby transferring energy from the transmitting coil to the receiving coil. The transfer of energy causes the charge of the electronic device to increase and the electronic device completes charging after a period of energy transfer.

Each electronic device has a corresponding charging rated power, and if the wireless charging device can provide the charging rated power for the electronic device, the electronic device can obtain wireless power according to a rated charging rate. If the power provided by the wireless charging device is less than the rated power for charging the electronic device, the charging rate of the electronic device is reduced, so that the charging time of the electronic device is longer.

For the wireless charging device, if a plurality of electronic devices are close to the wireless charging device, the wireless charging device needs to charge the plurality of electronic devices. When the output power of the wireless charging device cannot meet the charging rated power requirement of each electronic device, how to charge the plurality of electronic devices simultaneously by the wireless charging device becomes a technical problem to be solved urgently.

Detailed Description

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present embodiment, the meaning of "a plurality" is two or more unless otherwise specified.

By taking the WPT based on the electromagnetic induction principle as an example, the wireless charging device includes a plurality of transmitting coils, and the plurality of transmitting coils are arranged in a preset stacking manner, so that the wireless charging device can wirelessly charge the electronic device in a preset area. Wherein, due to the hardware design of the wireless charging device, the rated output power of the wireless charging device is fixed when the wireless charging device is wirelessly charged (for example, the wireless charging device provides 20W of output power). When the wireless charging device provides wireless power for the plurality of electronic devices, the sum of the wireless charging power received by the plurality of electronic devices is the rated output power of the wireless charging device.

For example, assuming that the rated output power of the wireless charging device is 20W (watt), the handset is placed on the wireless charging device, so that the wireless charging device provides wireless power to the handset. And if the rated charging power of the mobile phone is 10W, the wireless charging equipment provides wireless charging power for the mobile phone according to the rated charging power of the mobile phone.

When the sum of the rated charging powers of the plurality of electronic devices is the rated output power of the wireless charging device, the wireless charging device can provide the rated charging power for each electronic device. When the sum of the rated charging powers of the electronic devices is larger than the rated output power of the wireless charging device, the wireless charging device provides the wireless charging power for the electronic devices according to a preset power distribution principle. In this case, there must be at least one electronic device that receives a wireless charging power that is less than the rated charging power.

For example, assume that the rated output power of the wireless charging device is 20W. If the first electronic device is close to the wireless charging device, the rated charging power of the first electronic device is 20W, and the wireless charging device provides 20W of wireless charging power for the first electronic device. And if the first electronic device and the second electronic device are close to the wireless charging device, the rated charging power of the second electronic device is 2W. The wireless charging device can simultaneously transmit wireless power to the first electronic device and the second electronic device, and the sum of the rated charging power (namely 22W) of the first electronic device and the second electronic device is larger than the rated output power (20W) of the wireless charging device. In this case, the wireless charging device charges the first electronic device with an output power of 18W and charges the second electronic device with an output power of 2W according to a preset power distribution rule. The wireless charging power of the first electronic equipment is smaller than the rated charging power of the first electronic equipment.

In some implementations, the wireless charging device is a wireless charging dock, for example. The charging principle of the wireless charging base is that the charging time of a plurality of electronic devices is calculated, and the rated charging power of the electronic devices with short charging time is met as far as possible.

Supposing that the mobile phone and the smart bracelet can receive wireless power transmission, the mobile phone and the smart bracelet are placed on the wireless charging base, the wireless charging rated power of the wireless charging base is 20W, the charging rated power of the mobile phone is 20W, and the charging rated power of the smart bracelet is 2W. The wireless charging base calculates the possible charging time of intelligent bracelet and cell-phone, and it is shorter to confirm the charging time of intelligent bracelet, and then wireless charging base uses 2W's wireless charging power to charge for intelligent bracelet, and wireless charging base uses 18W's wireless charging power to charge for the cell-phone.

In other implementations, when the wireless charging base provides wireless power to the plurality of devices, the charging status of the plurality of devices may be displayed on one of the plurality of devices, so that the user may adjust the charging device according to the charging status.

For example, cell-phone, intelligent bracelet and panel computer all are placed at wireless charging base, and the cell-phone can establish communication connection through bluetooth and intelligent bracelet, acquires the current electric quantity value of intelligent bracelet. Furthermore, the mobile phone can be in communication connection with the tablet personal computer through the Bluetooth to acquire the current electric quantity value of the tablet personal computer. Therefore, the display screen of the mobile phone can display the current electric quantity values and the wireless charging power of the smart band and the tablet computer, and a user can acquire the current electric quantity values of the mobile phone, the smart band and the tablet computer when viewing a mobile phone interface, so that the user can view the charging state of any electronic equipment. If the user wants the tablet computer to complete charging as soon as possible, the mobile phone can be removed from the wireless charging base, so that the wireless charging power of the tablet computer is improved. Therefore, the wireless charging power of the tablet computer is the rated charging power, and the tablet computer can be charged as soon as possible.

In such implementations, a user may adjust the device being charged based on viewing the charging status of multiple electronic devices. If a user wishes to preferentially charge a certain electronic device, the user is required to monitor the charging state of the electronic device and manually adjust the device being charged, and the user experience is low.

Based on the implementation manner, it can be determined that, when the wireless charging device provides wireless charging for the plurality of electronic devices at the same time, the sum of the rated charging powers of the plurality of electronic devices is greater than the rated output power of the wireless charging device, and the wireless charging device can allocate the wireless charging power to the plurality of electronic devices according to a preset allocation manner (or called an algorithm). That is, the wireless charging device does not interact with the user and can wirelessly charge a plurality of electronic devices.

In this case, the wireless charging device cannot allocate the charging rated power according to the user's demand. For example, among a plurality of electronic devices, a user may want to prioritize charging of a first electronic device, i.e., the wireless charging device needs to allocate more power of wireless energy to the first electronic device to shorten the charging time of the first electronic device. Because the wireless charging device cannot interact with the user, the wireless charging device cannot acquire the user requirement, and the user requirement is difficult to meet.

The embodiment of the application provides a charging method which can be applied to wireless charging equipment. By the method provided by the embodiment of the application, the wireless charging equipment can interact with the user to obtain the user requirement in the process that the wireless charging equipment wirelessly charges at least two electronic devices. In this way, the wireless charging device can allocate rated power for wireless charging to at least two electronic devices according to the user's needs.

The charging method provided by the embodiment of the present application will be described below with reference to an application scenario.

The method provided by the embodiment of the application can be applied to a wireless charging scene, and the wireless charging device is taken as an example to provide wireless energy for a mobile phone, an intelligent bracelet and a tablet computer. Please refer to fig. 1A, which is a schematic diagram of a wireless charging scenario provided in the present application. As shown in fig. 1A, a mobile phone 200, a smart band 300 and a tablet computer 400 are placed on the wireless charging device 100, and the wireless charging device 100 is configured to provide wireless power for the mobile phone 200, the smart band 300 and the tablet computer 400. The rated wireless charging power of the wireless charging device 100 is 20W, the charging rated power of the mobile phone 200 is 20W, the charging rated power of the smart bracelet 300 is 2W, and the charging rated power of the tablet computer 400 is 20W.

For example, assume that the wireless charging device 100 does not have a display screen. The wireless charging device 100 identifies the mobile phone 200, the smart band 300 and the tablet computer 400, determines that the mobile phone 200, the smart band 300 and the tablet computer 400 all include a display screen, and the wireless charging device 100 interacts with a user by means of the display screen of the mobile phone 200. For example, the wireless charging apparatus 100 sends a prompt message to the mobile phone, where the prompt message is used to prompt the user whether to set a device to be charged preferentially. Among them, the device to be charged preferentially is a device to which more charging power is allocated, that is, an electronic device to which the user desires to complete charging as soon as possible.

The cellular phone 200 receives the prompt message from the wireless charging apparatus 100 and displays the prompt message. Please refer to fig. 1B, which is a schematic diagram of a prompt information interface displayed on a mobile phone. As shown in fig. 1B (a), the prompt information displayed on the display screen of the mobile phone 200 is: "whether or not to set a device to be charged with priority", and options "yes" and "no" corresponding to the prompt information. When the user wants the wireless charging device 100 to preferentially charge the mobile phone 200, the user clicks the "yes" option in the prompt interface shown in fig. 1B (a).

When the mobile phone receives the click operation of the user on the "yes" option, the mobile phone displays an interface as shown in (B) in fig. 1B, where the interface includes an identifier corresponding to the mobile phone 200, an identifier corresponding to the smart band 300, and an identifier corresponding to the tablet computer 400. If the mobile phone 200 receives a click operation of the user on the identifier corresponding to the mobile phone 200, it is determined that the user wants to set the mobile phone 200 as a device to be charged preferentially. In this way, the cellular phone 200 can transmit information for preferentially charging the cellular phone 200 to the wireless charging apparatus 100. The wireless charging device 100 receives information from the cell phone 200, and in response to the information, the wireless charging dock 100 preferentially charges the cell phone 200.

Wherein, if the wireless charging apparatus 100 has a display screen, the wireless charging apparatus 100 may display a prompt message and receive a user operation.

When the mobile phone 200, the smart band 300 and the tablet computer 400 are placed on the wireless charging base, the wireless charging device 100 is in communication connection with the mobile phone 200, the mobile phone 200 runs a wireless charging application, and the mobile phone 200 sends a first charging mode to the wireless charging device 100. The wireless charging device 100 receives the first charging mode from the mobile phone 200, determines that the current charging scene is the charging scene of the first charging mode, and then the wireless charging device 100 wirelessly charges the mobile phone 200, the smart band 300, and the tablet computer 400 according to the first charging mode.

In addition, the electronic device may be a vehicle-mounted computer, a Personal Digital Assistant (PDA), an Augmented Reality (AR) \ Virtual Reality (VR) device, or the like, and the embodiment of the present application is not particularly limited to a specific form of the electronic device.

The following describes a process of wireless power transmission by the wireless charging device 100 and the electronic device 500 in detail.

The wireless charging device 100 includes a transmitting coil therein, and the electronic device 500 includes a receiving coil therein. The transmitting coil may generate an alternating magnetic field in which the receiving coil induces an electric current when the electronic device 500 is positioned in the alternating magnetic field generated by the transmitting coil. For the purpose of the wireless charging device 100 transmitting wireless power to the electronic device 500.

Specifically, the wireless charging apparatus 100 and the electronic apparatus 500 perform wireless power transmission based on the gas (Qi) protocol. Please refer to fig. 4, which is a flowchart illustrating a wireless power transmission between the wireless charging apparatus 100 and the electronic apparatus 500. As shown in fig. 4, the radio power transmission procedure includes steps 401 to 408.

Step 401: the wireless charging device transmits a power detection broadcast for detecting devices receiving wireless energy.

Therein, the wireless charging device 100 may transmit the power probe broadcast periodically, such as every 30 seconds, 1 minute, 3 minutes, or 5 minutes. If the power probe broadcast is received, the wireless charging device may determine that a device receiving wireless energy is present within range of the wireless charging.

Illustratively, the wireless charging device 100 is configured to transmit the power probe broadcast every 400ms (milliseconds).

It is understood that transmitting the power detection broadcast by the wireless charging apparatus 100 may be understood as a selection phase (selection phase) of the wireless charging apparatus 100.

The electronic device 500 is in proximity to the wireless charging device 100, the wireless charging device 100 transmits a power probe broadcast, and the electronic device 500 receives the power probe broadcast transmitted by the wireless charging device 100, such that the wireless charging device 100 selects the electronic device 500 and transmits power to the electronic device 500.

Note that, the function of the wireless charging apparatus 100 in the selection phase is: it is detected whether there is a device receiving radio energy in the wireless charging range. The wireless charging device 100 transmits a power probe broadcast (or understood as an energy signal) and detects the value of the current flowing through the transmitting coil. The value of the current in the transmitting coil is maximal if no device receiving wireless energy is present in the wireless charging range. When the electronic device 500 is present in the wireless charging range, the wireless charging device 100 may detect that the current value of the transmission coil decreases. In this way, the wireless charging apparatus 100 determines that the electronic apparatus 500 is present in the wireless charging range, and transmits power to the electronic apparatus 500.

Step 402: the wireless charging device transmits power to the electronic device.

The wireless charging device 100 determines to transmit power to the electronic device 500 in the selection phase, and the wireless charging device 100 may continuously transmit power to the electronic device 500.

Step 403: the electronic device sends a signal strength identification packet to the wireless charging device according to the Qi protocol.

Here, the signal strength packet (SS packet) represents the strength of the energy picked up by the electronic device 500 (device receiving the wireless energy).

Step 404: the wireless charging apparatus receives the SS packet that satisfies the timing sequence and is correct.

Wherein the above steps 402-404 are referred to as ping phase (or referred to as handshake phase) of Qi protocol. The electronic device transmits the power strength data packet according to the Qi protocol, so that after the wireless charging device receives the power strength data packet of the Qi protocol, the wireless charging device may enter a power transfer identification and configuration phase.

For example, after the preset time period elapses while the wireless charging apparatus 100 continuously transmits power to the electronic apparatus 500, the wireless charging apparatus 10 receives the start bit of the SS packet, and the SS packet is correctly received by the wireless charging apparatus 100. The wireless charging device 100 enters the next phase of Qi charging. If the wireless charging apparatus 100 does not receive the start bit of the SS packet within the preset time period, the wireless charging apparatus repeatedly performs the selection phase (i.e., step 401).

Step 405: the electronic device sequentially sends the identification packet and the configuration packet to the wireless charging device.

The Identification packet (ID) may include information such as version information, manufacturer code, and device code of the electronic device 500, so that the wireless charging device 100 may identify the device of the electronic device 500.

The Configuration Packet (CP) may include information such as a maximum power and a power class of the electronic device 500, so that the wireless charging device 100 may configure the wireless charging power according to the CP Packet.

Step 406: the wireless charging device receives the ID packet and the CP packet from the electronic device in sequence, and a power transmission protocol is established.

Wherein steps 405 and 406 are the identification and configuration phases of the wireless power transfer. In the identification and configuration stage, the wireless charging device needs to identify the electronic device and collect configuration information of the electronic device. Therefore, the wireless charging apparatus needs to receive the ID packet and the CP packet set by the Qi protocol. Identification packets, extension identification packets, power control hold-off packets, configuration packets, and the like.

For example, after receiving the SS packet, the wireless charging apparatus 100 receives the start bit of the ID packet within a preset time period, and then determines that the wireless charging apparatus receives the ID packet. The wireless charging apparatus 100 receives the start bit of the CP packet within a preset time period after receiving the end bit of the ID packet. That is, when the wireless charging apparatus 100 determines that the ID packet and the CP packet are correctly received, the wireless charging apparatus 100 may create the power transmission parameter according to the information in the CP packet and enter the power transmission phase.

If the wireless charging device 100 receives the SS packet, the start bit of the ID packet is not received after a preset time period; or, the wireless charging device 100 receives the start bit of the ID packet, and after the ID packet is transmitted, the start bit of the CP packet is not received within a preset time length. The wireless charging device 100 may stop transmitting power to the electronic device 500.

If the order in which the wireless charging apparatus 100 receives the ID packets and the CP packets is erroneous or the contents in the ID packets and the CP packets are erroneous, the wireless charging apparatus 100 may stop transmitting power to the electronic apparatus 500.

Step 407: the wireless charging device dynamically adjusts the transmission power through proportional integral derivative according to the power required by the power transmission protocol.

The wireless charging device 100 may dynamically adjust the transmission power by using a proportional-integral-derivative (PID) according to the acquired CP packet, so that the transmission power of the wireless charging device may meet the charging requirement of the electronic device 500.

Step 408: the electronic device transmits the CE packet, the RP packet, the EPT packet, and the like to the wireless charging device.

Wherein step 407 and step 408 are power transmission phases of the wireless transmission device. The wireless charging apparatus 100 may provide wireless power according to the charging requirement of the electronic device 500, and if the wireless charging apparatus 100 detects an abnormal value, the wireless charging apparatus 100 stops transmitting power and returns to the selection stage (i.e., step 401). The abnormal value includes, but is not limited to, an abnormal transmission power, a power value received by the electronic device, and the like.

As can be appreciated, the Power transmission phase electronic device 500 transmits a Control error Packet (CE), a Received Power Packet (RP), and an End Power Transfer Packet (EPT) to the wireless charging device.

The CE packet includes a control error value, which is used to reflect the size of the control error in the wireless charging device and is an input parameter of the controller in the wireless charging device 100.

The RP packet includes a reception power value of the electronic device 500, and the reception power value reflects a value of power received by the electronic device 500.

The EPT packet includes a termination transmission code indicating a reason for terminating the power transmission. For example, the termination transmission code is 0x01, indicating that the reason for terminating the power transmission is that the charging is completed; the termination code is 0x03, indicating that the reason for terminating the power transmission is over-temperature, etc. Wherein the termination transmission code may be agreed in the Qi protocol.

Illustratively, after receiving the CP packet, the wireless charging device 100 receives the start bit of the CE packet within a preset time period, and correctly receives the CE packet. And after receiving the start bit of the CE packet, receiving the start bit of the RP packet within a preset time length, and correctly receiving the RP packet. The wireless charging apparatus 100 continuously transmits power to the electronic device 500, and when the wireless charging apparatus 100 receives the EPT packet from the electronic device 500, the wireless charging apparatus stops transmitting power to the electronic device 500.

If the wireless charging apparatus 100 does not receive the start bit of the CE packet for a preset time period after receiving the CP packet, the wireless charging apparatus 100 stops transmitting power to the electronic apparatus 500.

If the wireless charging device 100 does not receive the start bit of the RP packet within the preset time period after receiving the start bit of the CE packet, the wireless charging device 100 stops transmitting power to the electronic device 500.

The following will explain a charging method provided in an embodiment of the present application.

This application embodiment uses wireless charging equipment to be wireless charging base as an example, and electronic equipment includes: cell-phone, intelligent bracelet and panel computer. The charging method provided by the embodiment of the application is explained by using the wireless charging base to simultaneously provide wireless electric energy for the mobile phone, the smart band and the tablet computer as a charging scene.

Example 1

The mobile phone, the smart band and the tablet computer are placed on the wireless charging base at the same time, so that the wireless charging base provides wireless electric energy for the mobile phone, the smart band and the tablet computer at the same time. Among them, a mobile phone, a smart band, and a tablet computer are called as charged devices.

Please refer to fig. 5, which illustrates a charging method according to an embodiment of the present application. The charging method comprises steps 501-508.

Step 501: and in the identification and configuration stage of wireless charging, sending equipment information to the wireless base, wherein the equipment information comprises the equipment model.

Wherein, cell-phone, intelligent bracelet and panel computer send equipment information to wireless charging base respectively. The device information may include information such as a device model, a device hardware configuration, and the like. The data format of the device information may be a data format agreed with the wireless charging base so that the wireless charging base can recognize the corresponding device information.

In some implementations, if in the wireless charging identification and configuration phase, the wireless charging cradle does not receive device information sent by the electronic device (i.e., the cell phone, the smart band, and the tablet computer). The wireless charging base can establish a communication connection with an electronic device (for example, a mobile phone), for example, after the wireless charging base establishes a communication connection with the mobile phone, the wireless charging base can request the mobile phone to send device information, and the mobile phone sends the device information to the wireless charging base in response to the request.

Wherein, because the cell-phone is carrying out wireless charging, then the cell-phone is nearer with the distance of wireless charging base. Therefore, the wireless charging base and the mobile phone can establish communication connection by adopting a near field communication mode such as Bluetooth, NFC or WLAN.

Step 502: the wireless charging base identifies the equipment models corresponding to the mobile phone, the intelligent bracelet and the tablet computer according to the equipment information.

Illustratively, the device information may include a device model. For example, the device information of the mobile phone includes a product of xx brand xx model. The wireless charging base can determine relevant information of the mobile phone according to the model of the device, such as hardware information of the mobile phone, the type of a sensor in the mobile phone, a near field communication mode supported by the mobile phone and the like.

As yet another example, the device information may also include a device type. If the device information sent by the mobile phone to the wireless charging base comprises the mobile phone, the wireless charging base can determine to provide wireless electric energy for the mobile phone.

In some implementations, the wireless charging base may interact with a remote device (e.g., a server, a cloud device, etc.) to obtain information about the mobile phone based on the device signal. For example, the device information indicates that the mobile phone is a product of xx brand xx model, the wireless charging base interacts with the server, and the server is inquired about hardware information of the device corresponding to the xx brand xx model. The wireless charging base can determine whether the mobile phone supports near field communication or not and determine information such as the size of a display screen of the mobile phone according to hardware information sent by the server.

In other implementations, the wireless charging base may preset hardware information of the mobile phone, and after the wireless charging base receives the device information sent by the mobile phone, the wireless charging base determines the hardware information of the mobile phone and the like by querying the preset information.

It should be noted that the wireless charging base may preset a private protocol with the device to be charged (the mobile phone, the smart band, and the tablet computer), and the private protocol agrees with an information format of the mobile phone type. For example, the private protocol agrees to use a data string composed of 0 and 1 to represent the device information, and when the wireless charging base receives the device information composed of the data strings of 0 and 1, the device model of the charged device is determined according to the device information. For example, 0101 denotes a handset with a device type of model 1.

In some implementations, an equipment model lookup table may be preset in the wireless charging base, and the wireless charging base may determine the equipment model of the charged equipment according to the equipment information formed by the data strings of 0 and 1 from the charged equipment.

Step 503: the wireless charging base and the mobile phone are in communication connection.

It can be understood that the wireless charging base is selected to interact with the user by means of the mobile phone, and then the wireless charging base and the mobile phone establish communication connection. The mobile phone can send the received information corresponding to the user operation to the wireless charging base, and therefore the technical purpose of interaction between the wireless charging base and the user is achieved.

It should be noted that, here, it is an example that the wireless charging base interacts with the user by means of the mobile phone, and in practical applications, the wireless charging base may also interact with the user by means of the tablet computer. In other application scenarios, the wireless charging base may select an appropriate charged device for interaction with the user according to the model of the charged device.

It is worth mentioning that in some wireless charging scenarios, the wireless charging base is assumed to be a notebook computer, and the notebook computer provides wireless power for the mobile phone and the smart watch. In this case, the notebook computer may not interact with the charged device, and the notebook computer may interact with the user using its own external device (e.g., display, keyboard, mouse, etc.).

For example, when the wireless charging base receives the device information of all the charged devices, the wireless charging base determines the wireless charging rate of each charged device. These wireless charging ratios are combined into a set of recommended values, which the wireless charging base recommends as the wireless charging base to assign to each charged device.

The wireless charging base provides a wireless charging rate for each charged device according to the wireless charging rate in the recommended set of values.

Step 504: the wireless charging base sends prompt information to the mobile phone, and the prompt information is used for prompting a user whether to set a device which is charged preferentially or not.

Among these, the device to be charged with priority is a device to which more charging power is allocated.

It will be appreciated that a device that is preferentially charged is one that the user wishes to complete charging as quickly as possible. Therefore, the device to be charged with priority is supplied with electric energy according to the rated charging power of the device to be charged with priority, and the charging time of the device to be charged with priority can be effectively shortened. If the rated charging power for the device which is charged preferentially cannot be satisfied, the power proportion of the device which is charged preferentially is increased.

It should be noted that the wireless charging base may interact with the user via the electronic device being wirelessly charged to determine the device that is preferentially charged in the current charging scenario. The wireless charging base obtains device information of the electronic device, and the wireless charging base is helped to determine the device for interacting with the user.

In some implementations, the wireless charging base settings select to interact with the user through a larger device of a touch screen (or called a display screen). For example, the mobile phone, the smart band and the tablet computer are all in wireless charging, the wireless charging base determines that the display screen of the tablet computer is large according to the equipment information, the wireless charging base is in communication connection with the tablet computer, and interaction with a user is achieved through the tablet computer.

In other implementations, the wireless charging base may be further configured to interact through voice. If, wireless charging base provides wireless electric energy for intelligent bracelet, intelligent audio amplifier and panel computer simultaneously, and wireless charging base receives equipment information. The wireless charging base selects to adopt the intelligent sound box, and the mode through voice interaction is interactive with the user.

In other implementations, the wireless charging base may be configured to preferentially select interaction with the user via the mobile phone when the mobile phone is wirelessly charged. In the charging scene provided by the embodiment of the application, the wireless charging base receives the equipment information of the mobile phone, the intelligent bracelet and the tablet computer. The wireless charging base determines to employ a cell phone to interact with a user.

Step 505: the mobile phone receives the prompt message from the wireless charging base and displays the prompt message.

Wherein the hint information may include a wireless charging rate in the set of recommendation values.

Illustratively, the prompt message is: whether to set a device to be charged with priority. As shown in fig. 1B (a), the mobile phone displays the prompt message, so that the user can obtain the prompt message through the mobile phone. Further, the interface shown in fig. 1B (a) also includes a description of a device that is charged preferentially, such as "a device that is charged preferentially is a device to which more charging power is allocated".

In some implementations, the mobile phone displays the prompt, and if the mobile phone does not receive the user operation for a preset duration, the mobile phone may default that the user does not need to set the device to be charged preferentially.

Step 506: in response to an interaction with a user, the cell phone is determined to be a device that is preferentially charged.

The mobile phone displays an interface of the prompt message as shown in (B) in fig. 1B, and the main interface includes an equipment identifier of the mobile phone, an equipment identifier of the smart band, and an equipment identifier of the tablet computer. The mobile phone may obtain a click operation of the user on the device identifier in the main interface shown in (B) in fig. 1B, so as to determine the device to be charged preferentially.

For example, the mobile phone receives a click operation of the user on the device identifier of the mobile phone in the main interface shown in (B) in fig. 1B, and determines that the mobile phone is a device that is preferentially charged.

For example, the mobile phone may receive the device identifier of the mobile phone in the main interface shown in (B) in fig. 1B, and the mobile phone may also receive a click operation of the user on the device identifier of the smart band. In this case, it may be determined that the mobile phone is the device that is preferentially charged, and when the wireless charging base determines that the mobile phone is charged, the wireless charging base determines that the smart band is the device that is preferentially charged.

It can be understood that, in the process of interaction between the mobile phone and the user, the user can set the device to be charged preferentially through the mobile phone. Further, the user can set the wireless charging power of each charged device through the mobile phone. Wherein the wireless charging base determines a device model of the charged device, the wireless charging base may determine a charging power (e.g., a set of recommended values) of the charged device based on the device model.

For example, the wireless charging base sends a recommended value (e.g., a first recommended value or a second recommended value) of each charged device to the mobile phone, and the mobile phone displays the recommended value set, so that the user can view the recommended value set of the charged device through the mobile phone. When a user views the recommendation value set of the charged device displayed on the mobile phone, if the user wants to charge the charged device according to the recommendation value in the recommendation value set displayed on the mobile phone, it may be determined to provide wireless charging power for the charged device according to a wireless charging rate in the recommendation value set through interaction with the mobile phone. If the user does not want to provide the wireless charging power for the charged device according to the recommended value set displayed by the mobile phone, the wireless charging rate of the charged device (determined charging value) can be input into the mobile phone by interacting with the mobile phone, so that the mobile phone sends the wireless charging rate input by the user (or referred to as determined charging set) to the wireless charging base, and the wireless charging base can provide the wireless charging power for the charged device according to the wireless charging rate input by the user (determined charging set).

Wherein, the mobile phone receives the determined charging value input by the user. For example, the first electronic device corresponds to a first determined charging value, and the second electronic device corresponds to a second determined charging value. The mobile phone determines a charging set according to user operation and sends the determined charging set to the wireless charging base.

In a first implementation, the mobile phone displays an interface of the prompt message as shown in (a) in fig. 6A, and the mobile phone receives a click operation of a user on the device identifier of the mobile phone, where the device identifier of the mobile phone is marked as shown in (a) in fig. 6A, which indicates that the mobile phone is determined to be a device that is preferentially charged. If the mobile phone receives the click operation of the user on the device identifier of the mobile phone, the mobile phone is determined to be the device which is charged preferentially.

In response to receiving the selection operation of the priority charged device, the cellular phone displays a configuration power interface as shown in (b) in fig. 6A. The wireless charging base sends the recommended value set to the mobile phone, and the power configuration interface further comprises the recommended value set. The configuration power interface shown in fig. 6A (b) includes a power configuration item 61 of the mobile phone, a power configuration item 62 of the smart band, and a power configuration item 63 of the tablet computer. The recommended value in each power configuration item and the recommended value set of the mobile phone in the power configuration item 61 of the mobile phone are 70, namely 70% of rated output power of the wireless charging base is transmitted to the mobile phone; the recommended value of the power configuration of the smart band to the smart band in 62 is 10, namely 10% of the output power of the wireless charging base is transmitted to the smart band; the recommended value of the tablet computer in the power configuration item 63 of the tablet computer is 20, that is, 20% of the output power of the wireless charging base is transmitted to the tablet computer.

It is understood that each power configuration item also corresponds to a power recommendation range, for example, the power recommendation range corresponding to the power configuration item 61 of the mobile phone is 0-70. When the mobile phone receives the power setting of the user to the mobile phone, as shown in (c) in fig. 6A, the charging power of the mobile phone, which is received by the mobile phone and set by the user, is 65.

For example, when the handset receives a setting for the power of the charged device, the power setting item of the charged device will not display the recommended value. As shown in the interface in fig. 6A (c), the power received by the mobile phone is configured by the user as 65% of the allocated charging power of the mobile phone (e.g., referred to as a first determined charging value), 10% of the allocated charging power of the smart band (e.g., referred to as a second determined charging value), and 20% of the allocated charging power of the tablet computer (e.g., referred to as a third determined charging value).

In the second implementation, the wireless charging base can determine the priority charging sequence of the charged device under the condition that the wireless charging base provides wireless energy for the mobile phone, the smart band and the tablet computer. When the wireless charging base sends prompt information to the mobile phone, the prompt information comprises the priority charging sequence of the charged equipment, so that a user can know the priority charging sequence of the charged equipment through an interface displayed by the mobile phone.

As shown in fig. 6B (a), a prompt information interface is displayed for the mobile phone. As shown in fig. 6B (a), the priority charging order in the prompt message is 1, mobile phone, 2, tablet computer, and 3 smart band. The prompt information is specifically "whether to adjust the charging order of the charged device" (i.e., set the priority of the charged device).

If the mobile phone receives the click operation of the user on the adjustment option, a charging sequence (i.e. priority) interface for selecting the charged device is displayed as shown in (B) in fig. 6B. And if the mobile phone receives the clicking operation of the user on the non-adjustment option, the mobile phone does not display the prompt message. Taking the operation of the user on the adjustment option received by the mobile phone as an example, the interface shown in (B) in fig. 6B includes the device identifier of the mobile phone, the device identifier of the smart band, and the device identifier of the tablet computer. The handset receives a user selection operation of a device identifier for the first time, and the device identifier is marked as 1. As shown in fig. 6B (B), the device identifier of the mobile phone is labeled as 1, the device identifier of the smart band is labeled as 2, and the device identifier of the tablet computer is labeled as 3.

For example, when the mobile phone determines the charging sequence of the charged device, the mobile phone may set the charging power according to the charging sequence (i.e., priority), and sequentially provide the wireless charging rate for the mobile phone, the smart band, and the tablet computer according to the charging priority.

For example, the wireless charging base provides a wireless charging rate of 70% for the mobile phone, the smart band provides a wireless charging rate of 10%, and the tablet computer provides a wireless charging rate of 20%. And when the electric quantity of the mobile phone is 100%, determining that the mobile phone is charged. Further, the wireless charging base provides 20% (wherein, the rated charging power of intelligent bracelet is 20% of wireless charging base output power) wireless charging rate for the intelligent bracelet, and the wireless charging base provides 80% wireless charging rate for the panel computer. When the electric quantity of intelligent bracelet is 100%, confirm that intelligent bracelet accomplishes and charge. The wireless charging base can provide wireless electric energy for the tablet computer according to the rated charging power of the tablet computer.

As another example, when the handset determines the priority of the charged device, the handset may display a configuration power interface as shown in fig. 6B (c). The mobile phone can receive power settings of a user on a plurality of charged devices and provide wireless charging rates for the charged devices according to the set charging power.

A power distribution interface as shown in (c) of fig. 6B, which includes power configuration items, power recommendation values, etc. of the charged device. It should be noted that the interface shown in fig. 6B (c) is the same as the interface shown in fig. 6A (B), and the operation of the power distribution interface shown in fig. 6B (c) is the same as the operation of the interface shown in fig. 6A (B), which is not repeated herein.

In a third implementation, the wireless charging base sends a prompt message to the mobile phone, where the prompt message is used to indicate whether to configure charging power for the multiple charged devices. As shown in fig. 6C (a), the mobile phone displays a prompt interface, which includes prompt information. The prompt interface also comprises option controls, namely a corresponding option control of 'yes' and a corresponding option control of 'no'. The prompt interface also comprises an operation prompt corresponding to each option control.

Wherein, if the mobile phone receives a click operation of the yes option control by the user, in response to the click operation, the mobile phone displays a power distribution interface as shown in (b) of fig. 6C. And if the mobile phone receives the clicking operation of the user on the 'NO' option control, responding to the clicking operation, and distributing the wireless charging rate to the plurality of charged equipment by the mobile phone according to a preset charging power distribution rule.

It is worth mentioning that when the handset displays the power distribution interface (i.e., the interface shown in (B) in fig. 6A, the interface shown in (C) in fig. 6B, and the interface shown in (B) in fig. 6C), the power distribution interface includes the set of recommended values for each charged device, which are set by the wireless charging base.

The principle of the wireless charging cradle distributing charging power to the charged device will be explained below.

The wireless charging base is preset with a charging power distribution rule, and when the wireless charging base determines that a plurality of charged devices exist and the sum of the rated charging power of the plurality of charged devices is larger than the rated output power of the wireless charging base. The wireless charging base distributes charging power for the plurality of charged devices according to a preset charging power distribution rule to obtain a recommendation value set.

For example, the wireless charging base may classify the charged devices into a plurality of categories according to the rated charging power of the charged devices, taking the wireless charging base as an example to classify the charged devices into three categories. For example, a mobile phone, a tablet computer, a notebook computer and the like are set as the first type of charged equipment; earphones, watches and the like are set as second-type charged equipment; VR glasses and electron ring etc. set up to the third type by the battery charging outfit.

Wherein, the charging rule may further include: when only the same kind of charged devices (e.g., the first kind of charged devices) are placed on the wireless charging dock, the wireless charging dock allocates charging power to the plurality of charged devices according to the ratio of the rated charging power of each charging device.

For example, the mobile phone 1, the mobile phone 2 and the tablet computer are placed on the wireless charging base, the rated charging power of the mobile phone 1 is 10W, the rated charging power of the mobile phone 2 is 10W, and the rated charging power of the tablet computer is 15W. The wireless charging base determines that the ratio of the rated charging power of each charging device is 2:2:3, the rated output power of the wireless charging base is 20W, the wireless charging ratio transmitted by the wireless charging base to the mobile phone 1 is 5.7W, the wireless charging ratio transmitted by the wireless charging base to the mobile phone 2 is 5.7W, and the wireless charging ratio transmitted by the wireless charging base to the tablet personal computer is 8.6W.

When the wireless charging base determines that at least one type of charged equipment exists, the wireless charging base distributes charging power for each type of charged equipment according to a preset proportion. If the charged devices on the wireless charging base comprise the first type of charged devices and the second type of charged devices, the first type of charged devices are allocated with a wireless charging rate of 70%, and the second type of charged devices are allocated with a wireless charging rate of 30%. For another example, the charged devices on the wireless charging base include a first type of charged device, a second type of charged device and a third type of charged device, the first type of charged device is assigned a wireless charging rate of 50%, the second type of charged device is assigned a wireless charging rate of 30%, and the third type of charged device is assigned a wireless charging rate of 20%.

Wherein, if the type of the charged device comprises more than one electronic device, the wireless charging rate can be allocated according to the rated charging proportion of the plurality of electronic devices.

It should be noted that the percentage of the allocated wireless charging ratio in the above example is only an example, and the specific value may be set according to the actual situation.

For example, the wireless charging base provides a wireless charging ratio for the mobile phone, the tablet personal computer and the smart band, since the mobile phone and the tablet personal computer are the first type of charged devices and the smart band is the second type of charged devices, taking the rated output power of the wireless charging base as 20W as an example. The handset and the tablet computer are allocated with a wireless charging rate of 70% (i.e., 14W), and the smart band is allocated with a wireless charging rate of 30% (i.e., 6W). Because the rated charging power of intelligent bracelet is 2W, that is to say, wireless charging base is wireless charging rate 10% (2W) at most for intelligent bracelet, like this, wireless charging base adjustment power distribution distributes 90% wireless charging rate for cell-phone and panel computer, distributes 10% wireless charging rate for intelligent bracelet.

For another example, a mobile phone and a smart watch are placed on a wireless charging base, the wireless charging base identifies the model of a device to be charged (i.e., the mobile phone and the smart watch), and based on a preset wireless power distribution rule, the wireless charging base may distribute a wireless charging rate of 80% to the mobile phone and a wireless charging rate of 20% to the smart watch (assuming that the wireless charging rate of 20% is exactly the rated charging power of the smart watch). If the user wants to modify the assigned wireless charging rate, the wireless charging base may determine to assign a wireless charging rate of 90% to the cellular phone and a wireless charging rate of 10% to the smart watch according to the user setting information (determine charging set).

As another example, a mobile phone and an earphone box (wireless earphone) are placed on a wireless charging base, and the wireless charging base provides wireless power to the mobile phone and the earphone box at the same time. The wireless charging base identifies the model of the device to be charged (i.e. the mobile phone and the earphone box), and based on the preset wireless charging rule, the wireless charging base can allocate a wireless charging rate of 70% to the mobile phone and a wireless charging rate of 30% to the earphone box according to the preset charging power allocation rule (assuming that the wireless charging rate of 30% is the rated charging power of the earphone box). If the user wants to modify the allocated wireless charging rate, the wireless charging cradle may determine to allocate a wireless charging rate of 10% (second determined charging value) to the earphone box according to the user setting information (determined charging set), for example, it is determined to allocate a wireless charging rate of 90% (first determined charging value) to the cellular phone and a wireless charging rate of 10% (second determined charging value) to the earphone box. Generating a determined charging set from the first determined charging value and the second determined charging value.

For another example, the mobile phone, the smart watch and the earphone box are all placed on the wireless charging base, and the wireless charging base provides wireless electric energy for the mobile phone, the smart watch and the earphone box simultaneously. The wireless charging base determines a device signal of a charged device according to the device information, namely the wireless charging base determines to provide wireless electric energy for the mobile phone, the smart watch and the earphone box, and based on a preset charging rule, the mobile phone can allocate a wireless charging rate of 50% to the mobile phone, allocate a wireless charging rate of 20% to the smart watch and allocate a wireless charging rate of 30% to the earphone box. If the user wants to modify the allocated wireless charging rate, the wireless charging cradle may determine to allocate the wireless charging rate of 80% to the cellular phone, 10% to the smart watch, and 10% to the earphone box according to the user setting information (determine charging set).

Step 507: and the mobile phone sends the information that the mobile phone is the equipment which is charged preferentially to the wireless charging base.

In the first implementation, it is determined that the device to be charged preferentially is the mobile phone in response to the operation of the user, and the mobile phone sends information that the mobile phone is the device to be charged preferentially to the wireless charging base.

If, in response to a user's operation, it is determined that both the handset and the smartphone are charged devices. After the user selects the device identifier of the mobile phone, the mobile phone receives the selection operation of the user on the device identifier of the smart band, and the mobile phone receives the selection operation of the user on the completion control. Therefore, the mobile phone and the intelligent bracelet are determined to be the prior charged devices, the mobile phone sends information of the prior charged devices to the wireless charging base, and the information comprises the mobile phone and the intelligent bracelet.

It will be appreciated that the user may select at least one device as the device to be charged preferentially.

For example, the mobile phone determines a charging power value of a device to be charged preferentially and at least one charging device of the plurality of charging devices, and the mobile phone sends information of the device to be charged preferentially to the wireless charging base. Wherein the information of the devices that are preferentially charged includes an identification of the devices that are preferentially charged and a charging power value of the at least one charging device.

If the mobile phone determines that the device which is charged preferentially is the mobile phone, and receives the setting information that the configuration power of the mobile phone is 70%, the device identification of the mobile phone and the configuration power of the mobile phone are sent to the wireless charging base.

Step 508: the wireless charging base transmits wireless electric energy of first charging power to the mobile phone, transmits wireless electric energy of second charging power to the intelligent bracelet, and transmits wireless electric energy of third charging power to the tablet personal computer. And the value of the first charging power is larger than the sum of the second charging power and the third charging power.

Illustratively, the wireless charging base receives information of a device to be charged in priority, and the wireless charging base determines the device type of the device to be charged in priority according to the information. The wireless charging device allocates charging power to each charged device according to the device type of the device to be charged in priority and the device types of other charged devices. The wireless charging base can distribute charging power for the equipment which is charged preferentially according to a preset power distribution algorithm.

For example, the wireless charging base can determine that the mobile phone is a device to be charged preferentially according to the information (priority) of the device to be charged preferentially, which is sent by the mobile phone. The information of the device preferentially charged indicates that a 70% wireless charging rate is allocated to the mobile phone, a 5% wireless charging rate is allocated to the smart band, and a 25% wireless charging rate is allocated to the tablet computer. In response to receiving the above information, the wireless charging base allocates a 70% wireless charging rate (i.e. 14W) to the mobile phone, allocates a 5% wireless charging rate (i.e. 1W) to the smart band, and allocates a 25% wireless charging rate (i.e. 5W) to the tablet.

As another example, the wireless charging base receives information (priority) of a device that is preferentially charged, from which it can be determined that the mobile phone is a device that is preferentially charged, and the information indicates that a 70% wireless charging rate is allocated for the mobile phone. Since the information does not include the allocated power of other charged devices (charged devices other than the mobile phone), the wireless charging base can allocate wireless charging rates to the other charged devices according to the preset charging rules. The wireless charging base allocates 70% wireless charging rate (i.e. 14W) for the mobile phone, 10% wireless charging rate (i.e. 2W) for the smart band, and 20% wireless charging rate (i.e. 4W) for the tablet computer.

It should be noted that, in the process of providing the wireless charging rate for the plurality of charged devices by the wireless charging base, if the user wants to adjust the priority charging sequence of the charged devices, the user may interact with the wireless charging base through the mobile phone to change the priority charging sequence of the charged devices. Alternatively, if the user wants to change the charging power of the charged device, the user may interact with the wireless charging base through the mobile phone to change the configured charging power.

In some implementations, the mobile phone receives the operation of adjusting the charging power, and the mobile phone sends information to change the configured charging power to the wireless charging base. The wireless charging base receives the information of changing the configuration charging power, sends configuration changing prompt information to the mobile phone and displays the information. The mobile phone receives the configuration change information from the wireless charging base and displays the configuration change information.

As shown in fig. 7 (a), the configuration change interface includes the charging power of the currently charged device, and displays the query information of "whether to change the configured charging power", and the "yes" option control and the "no" option control. In response to the cell phone receiving a user click operation on the "yes" option control, the cell phone displays a power allocation interface as shown in fig. 7 (b). As shown in fig. 7 (b), the power allocation interface includes a power configuration item 61 of the mobile phone, a power configuration item 62 of the smart band, and a power configuration item 63 of the tablet computer. And the percentage of the current wireless charging rate of the charged device, such as a wireless charging rate of 45% corresponding to the mobile phone, a wireless charging rate of 10% corresponding to the smart band, and a wireless charging rate of 45% corresponding to the tablet computer.

It will be appreciated that the handset may receive a user input of a percentage of the wireless charging rate. As shown in the power allocation interface of fig. 7 (c), the handset receives the wireless charging ratio percentage 70 entered by the user at the power configuration item 61 of the handset. In this case, the percentage numbers in the power configuration item 62 of the smart band and the power configuration item 63 of the tablet are also adaptively adjusted. The mobile phone may further receive the wireless charging rate percentage of the smart band input by the user, and/or the wireless charging rate percentage of the tablet computer input by the mobile phone.

It should be noted that, when the mobile phone receives a click operation of the determination control 65 in the power distribution interface shown in fig. 7 (c), the mobile phone sends the wireless charging rate to the wireless charging base. The wireless charging base provides wireless charging power to the charged device according to a wireless charging rate.

During the process that the wireless charging base provides wireless charging power to the charged device, if a user wants to modify the prior charged device, or the user wants to adjust the wireless charging ratio of the charged device; the user may interact with the handset so that the handset displays an interface as shown in fig. 7 (a).

Example 2

The mobile phone, the smart band and the tablet computer are placed on the wireless charging base at the same time, so that the wireless charging base provides wireless electric energy for the mobile phone, the smart band and the tablet computer at the same time. The wireless charging application is installed in the mobile phone, the mobile phone runs the wireless charging application, and the charging mode of the wireless charging base can be set.

Please refer to fig. 8, which is a flowchart illustrating a charging method according to an embodiment of the present disclosure. As shown in fig. 8, the method includes steps 801-805.

Step 801: the wireless charging base transmits first power to the cell-phone, transmits second power to intelligent bracelet, transmits third power to the panel computer.

The wireless charging base is in a transmitting power stage, and the mobile phone, the smart band and the tablet computer receive charging power transmitted by the wireless charging base.

It can be understood that the wireless charging base allocates charging power (recommended value set) for the mobile phone, the smart band and the tablet computer according to a preset power allocation principle, and provides wireless power for each device according to the charging power.

If the wireless charging base recommends that a first recommended value is distributed to the mobile phone, a second recommended value is distributed to the smart bracelet, and a third recommended value is distributed to the tablet computer.

Step 802: the wireless charging base is in communication connection with the mobile phone.

The wireless charging application is installed in the mobile phone, the mobile phone is connected with the wireless charging base, and then the wireless charging base can receive information sent by the mobile phone.

In some implementations, the mobile phone, the smart band, and the tablet computer are all placed on the wireless charging base, and the wireless charging base provides wireless power for the mobile phone, the smart band, and the tablet computer. Illustratively, a wireless charging application is installed in the mobile phone, and the mobile phone may display an interface as shown in fig. 10A (a). As shown in fig. 10A (a), the wireless charging device 92 is included, and when the user views the interface 92 displayed on the mobile phone, the user can know that the wireless charging base is charging the mobile phone.

In this case, if the mobile phone receives a click operation of the wireless charging application 901 from the user, and the mobile phone runs the wireless charging application, the mobile phone may display an interface as shown in (b) in fig. 10A.

If the current charging scene is preset by the wireless charging application in the mobile phone, for example, the first charging scene of the mobile phone includes the mobile phone, the smart band and the tablet computer. The mobile phone runs a wireless charging application, the mobile phone is interactive with the charging base, and the wireless charging base provides wireless electric energy for the plurality of charged devices according to a first charging scene preset by the mobile phone. In this process, the wireless charging base provides wireless power to the plurality of charged devices without the user feeling (i.e., the mobile phone does not need to interact with the user).

It can be understood that, in the manner of presetting the first charging scenario in the wireless charging application of the mobile phone, the first charging scenario may be created in the manner shown in fig. 9.

If the current charging scenario is not preset in the wireless charging application in the mobile phone, the mobile phone displays an interface as shown in (b) of fig. 10A. As shown in fig. 10A (b), the interface includes a label 93 of the currently charged device, that is, a label 93 of the mobile phone, a label 94 of the smart band, and a label 95 of the tablet computer; and create as my charging scenario control 96. Taking the mark 93 of the mobile phone as an example, the wireless charging base provides wireless electric energy for the mobile phone, the smart band and the tablet computer, and the wireless charging base can provide wireless electric energy for a plurality of charged devices according to the principle that the preset charged devices distribute charging power. The label 93 of the handset corresponds to the device identification of the handset, the device name (e.g., handset), and the current wireless charging rate (e.g., 70%) of the device.

It will be appreciated that if the user wants to change the wireless charging rate of the device being charged, the handset may receive a user input of the wireless charging rate.

For example, if the user wants to set the current charging scenario as one charging scenario, the user may click to create as my charging scenario 96. When the mobile phone receives a click operation of the user on the charging scene 96 created as my, the mobile phone may display an interface as shown in fig. 9 (c), so that the mobile phone creates a wireless charging scene.

It should be noted that, if the current charging scenario is preset in the mobile phone. The mobile phone displays an interface shown in fig. 10B (a), receives a click operation of the wireless charging application 901 by the user, and displays an interface shown in fig. 10B (B). The interface shown in fig. 10B (B) includes that the current charging scenario is a preset first charging scenario, and includes the identifier, name and charging power percentage of each charged device. If the user wants to change the charging power setting item of the current charging scene, such as the charging power percentage of the charged device, the mobile phone may receive a click operation of the user on the setting item. The mobile phone can adjust the setting items in the first charging scene according to the received user operation information.

Step 803: the mobile phone runs a wireless charging application, the wireless charging application comprises a charging mode of a first charging scene, and the first charging scene indicates the wireless charging base to provide wireless electric energy for the mobile phone, the intelligent bracelet and the tablet computer.

The mobile phone can run the wireless charging application no matter whether the mobile phone is wirelessly charged or not, and can receive a wireless charging scene set by a user.

The handset displays a main interface as shown in fig. 9 (a), which includes a wireless charging application 901. In response to a click operation of the wireless charging application 901 by the user, the cell phone displays a wireless charging application interface as shown in fig. 9 (b). The interface shown in fig. 9 (b) includes all charging scenarios in the wireless charging application, and a control to create the charging scenarios. In response to a click operation by the user to create a charging scene, the handset displays the identification of the charged device as shown in fig. 9 (c). The interface shown in fig. 9 (c) includes an additional device control, and when the mobile phone receives a click operation of the additional device control by the user, the mobile phone displays a plurality of device identifiers capable of performing wireless charging. As shown in fig. 9 (c), the currently created scene includes the device identifier of the mobile phone, the device identifier of the smart band, and the device identifier of the tablet computer. In response to the user clicking the completion control, the mobile phone displays an interface as shown in (d) of fig. 9. The interface shown in fig. 9 (d) includes a configuration charging power item corresponding to each charged device, and each configuration charging power item may receive input data. Thus, creation of a charging scene is completed.

For example, in a first charging scenario, the wireless charging base charges a mobile phone, an intelligent bracelet and a tablet computer. The charging power of the mobile phone is set to be 70%, the charging power of the smart band is 10% (the rated charging power of the smart band is 20%), and the charging power of the tablet personal computer is 20%.

Step 804: the mobile phone sends the charging mode of the first charging scene to the wireless charging base in a wireless communication mode.

The charging mode of the first charging scene is that the charging power of the mobile phone is the fourth power, the charging power of the smart band is the fifth power, and the charging power of the tablet personal computer is the sixth power.

It should be noted that the charging mode of the first charging scenario is the same as the charging mode of the wireless charging base in the current charging, that is, the power allocated by the wireless charging base to each device conforms to the setting information of the first charging scenario, and the wireless charging base does not need to adjust the charging power.

Step 805: the wireless charging base determines that the current charging scene accords with the first charging scene, transmits fourth power to the mobile phone, transmits fifth power to the smart band, and transmits sixth power to the tablet computer.

The wireless charging base provides wireless electric energy for cell-phone, intelligent bracelet and panel computer according to the setting parameter in the first scene of charging.

The above description is given by taking the wireless charging device as a wireless charging base, and the wireless charging base interacts with a user through a mobile phone, and when the wireless charging base is other wireless charging devices and the mobile phone is other devices, the above method may also be used to provide wireless power.
