Description

Technical Field

[0001] This application relates to the field of wireless power transmission technology, and in particular to a charging method, wireless charging device and related equipment. Background Technology

[0002] Wireless Power Transmission (WPT) is a technology that transfers electrical energy without physical contact. The principles behind WPT include electromagnetic induction, microwave power transmission, and electromagnetic field resonance. Taking WPT using electromagnetic induction as an example, the wireless charging device includes a transmitting coil, and the electronic device receiving wireless power (e.g., a mobile phone, a smartwatch) includes a receiving coil. The transmitting coil of the wireless charging device is connected to an AC power source, generating an alternating magnetic field within it. When the electronic device approaches the wireless charging device, the alternating magnetic field of the transmitting coil induces a current in the receiving coil, transferring energy from the transmitting coil to the receiving coil. This energy transfer increases the charge level of the electronic device, and after a period of time, the device is fully charged.

[0003] Understandably, when an electronic device is near a wireless charging device, the wireless charging device can charge the device. Each electronic device has a corresponding rated charging power. If the wireless charging device can provide the rated charging power, the electronic device can obtain wireless power at the rated charging rate. If the power provided by the wireless charging device is less than the rated charging power of the electronic device, the charging rate will decrease, resulting in a longer charging time.

[0004] For wireless charging devices, if multiple electronic devices are near the device, the device needs to charge all of them. When the output power of the wireless charging device cannot meet the rated charging power requirements of each electronic device, how to charge multiple devices simultaneously becomes a pressing technical problem. Summary of the Invention

[0005] This application provides a charging method, a wireless charging device, and related equipment, enabling the wireless charging device to charge multiple electronic devices.

[0006] To achieve the above technical objectives, this application adopts the following technical solution:

[0007] Firstly, this application provides a charging method applicable to a wireless charging system. The wireless charging system includes a wireless charging device and at least two devices to be charged, such as a first electronic device and a second electronic device. The wireless charging device can simultaneously provide wireless power to the at least two devices. The first electronic device also includes a display screen for acquiring user input.

[0008] Specifically, the charging method may include: the wireless charging device receiving device information from a first electronic device and a second electronic device, respectively, and determining a set of recommended values ​​based on the device information. The set of recommended values ​​includes recommended wireless charging ratios allocated to the first electronic device and the second electronic device. For example, the set of recommended values ​​may include multiple recommended values, with the recommended wireless charging ratio allocated to the first electronic device being a first recommended value, and the recommended wireless charging ratio allocated to the second electronic device being a second recommended value.

[0009] The wireless charging device transmits wireless power to a first electronic device and a second electronic device according to the wireless charging ratio in a recommended value set. To receive user input, the wireless charging device can interact with the user via the display screen of the first electronic device to obtain user input information. The wireless charging device sends the recommended value set to the first electronic device, which, upon receiving the set, displays a first interface including the wireless charging ratio in the recommended value set.

[0010] When a user views the first electronic device, they will see a first interface. Upon receiving a user action, the first electronic device responds by generating a determined charging set. This determined charging set includes determining the wireless charging ratio allocated to both the first and second electronic devices. For example, the determined charging set may include a first determined charging value and a second determined charging value, where the first determined charging value is the wireless charging ratio allocated to the first electronic device, and the second determined charging value is the wireless charging ratio allocated to the second electronic device.

[0011] The first electronic device sends a defined charging set to the wireless charging device, and the wireless charging device sends wireless power to the first electronic device and the second electronic device according to the wireless charging ratio in the defined charging set (e.g., a first defined charging value and a second defined charging value).

[0012] During the charging process described above, when the first and second electronic devices are close to the wireless charging device, the wireless charging device provides wireless power to both devices. Specifically, the wireless charging device provides wireless power to the first and second electronic devices according to a recommended set of values. To provide a better user experience, the wireless charging device sends the recommended set of values ​​to the first electronic device, which then displays the wireless charging ratio within that set. The user can see this recommended charging ratio on the first electronic device's screen. If the user wants to change the wireless charging ratio of a particular device (such as the first electronic device), the first electronic device can receive the user's action and, in response, generate a specific charging set.

[0013] Understandably, determining the charging set includes determining the wireless charging ratio allocated to the first and second electronic devices, which is based on user actions. The first electronic device sends the determined charging set to the wireless charging device, and the wireless charging device transmits wireless power to the first and second electronic devices according to the wireless charging ratio in the determined charging set. In this charging method, the wireless charging device can interact with the user through the first electronic device, obtain user actions, and determine the user's charging needs for the first and second electronic devices. The wireless charging device can then provide wireless power to the first and second electronic devices according to the user's needs.

[0014] Secondly, this application also provides a charging method that can be applied to a wireless charging device, which can simultaneously provide wireless power to at least two devices being charged. The at least two devices being charged may include a first electronic device and a second electronic device.

[0015] Specifically, the charging method includes: receiving device information from a first electronic device and a second electronic device respectively; determining a set of recommended values ​​based on the device information, the recommended values ​​including a wireless charging ratio recommended for the first electronic device and the second electronic device; and the wireless charging device transmitting wireless power to the first electronic device and the second electronic device according to the wireless charging ratio in the set of recommended values.

[0016] The wireless charging device can send a set of recommended values ​​to a first electronic device, causing the first electronic device to display the set of recommended values. Further, the wireless charging device receives a determined set of charging values ​​from the first electronic device, the determined set of charging values ​​including determining a wireless charging ratio allocated to both the first and second electronic devices. The wireless charging device then transmits wireless power to both the first and second electronic devices according to the wireless charging ratio in the determined recommended values.

[0017] Understandably, after the wireless charging device sends wireless power to the first and second electronic devices, it interacts with the user through the first electronic device to obtain the user's needs. Therefore, the wireless charging device can obtain the user's charging needs for the devices being charged through the first electronic device, and based on this, the wireless charging device sends a set of recommended values ​​to the first electronic device. When the electronic device obtains a set of determined charging values, since this set is based on user actions, the wireless charging device obtains the user's needs based on this set. The wireless charging device then sends wireless power to the first and second electronic devices according to the wireless charging ratio in the determined charging set. In this way, the wireless charging device can provide wireless power to the first and second electronic devices according to the user's needs.

[0018] In one possible design approach of the second aspect, determining the recommended value set based on device information may specifically include: determining a first recommended value and a second recommended value based on device information, where the first recommended value is a wireless charging ratio recommended for the first electronic device, and the second recommended value is a wireless charging ratio recommended for the second electronic device. The wireless charging device determines the recommended value set according to the first and second recommended values.

[0019] The first and second recommended values ​​are the wireless charging ratios recommended by the wireless charging device for allocating power to the first and second electronic devices according to preset rules. For example, the preset rules could be to distribute wireless power evenly among multiple devices being charged.

[0020] In another possible design approach, the device information includes device type and rated charging power. Before determining the first and second recommended values ​​based on the device information, the method may include: determining whether the device types of the first electronic device and the second electronic device are the same.

[0021] If it can be determined that the first electronic device and the second electronic device are of the same device type, then determining the first recommended value and the second recommended value based on the device information may specifically include: calculating the ratio of the rated charging power of the first electronic device to the rated charging power of the second electronic device, and determining the first recommended value and the second recommended value based on this ratio. The first recommended value is the wireless charging ratio allocated by the wireless charging device to the first electronic device, and the second recommended value is the wireless charging ratio allocated by the wireless charging device to the second electronic device.

[0022] It should be noted that device type categorizes one or more devices into a single type. For example, the first device type includes: mobile phones, tablets, etc.; the second device type includes: smartwatches, smart bracelets, and earphone cases, etc.; and the third device type includes: low-power electronic devices such as smart glasses. This is just an example. For instance, if the first electronic device is a mobile phone and the second electronic device is a tablet, then it can be determined that the first and second electronic devices have the same device type.

[0023] In other implementations, the first electronic device can be exactly the same as the second electronic device, in which case it can be determined that the first electronic device and the second electronic device have the same device type. For example, if both the first electronic device and the second electronic device are mobile phones, then it can be determined that the first electronic device and the second electronic device have the same device type.

[0024] The device types can include mobile phones, tablets, smartwatches, etc. For example, if the first electronic device is a mobile phone, it can send device information to the wireless charging device, and the wireless charging device can identify that the first electronic device is a mobile phone.

[0025] In another possible design approach, the device information includes the device type. The determination of the first and second recommended values ​​based on the device information specifically includes: determining that the first electronic device is a first type of device and the second electronic device is a second type of device based on the device information; determining a first preset ratio based on the first type of device and a second preset ratio based on the second type; setting the first recommended value of the first electronic device to the first preset ratio and the second recommended value of the second electronic device to the second preset ratio.

[0026] The wireless charging device can set a first preset ratio for a first type of device and a second preset ratio for a second type of device. The wireless charging device provides wireless power to the first type of device according to the first preset ratio and to the second type of device according to the second preset ratio.

[0027] In some implementations, if the wireless charging device also includes a third electronic device, and the first electronic device is a first type of device, while the second and third electronic devices are third type of devices, then the wireless charging device transmits wireless power to the first electronic device according to a first preset ratio, i.e., the first preset ratio is a first recommended value. A second preset ratio is allocated based on the ratio of the rated charging power of the second and third electronic devices. A second recommended value for the second electronic device and a third recommended value for the third electronic device are calculated. The wireless charging device then transmits wireless power to the second electronic device according to the second recommended value and to the third electronic device according to the third recommended value.

[0028] In another possible design approach, the charging power ratio in the set of charging values ​​is determined to be different from the charging power ratio in the set of recommended values.

[0029] In another possible design approach, the above method further includes: receiving the priority of the device being charged sent by the first electronic device, and determining a first recommended value and a second recommended value based on the priority of the device being charged.

[0030] Thirdly, this application also provides a charging method applied to a wireless charging device, wherein the wireless charging device can simultaneously provide wireless power to at least two devices being charged. The at least two devices being charged may include a first electronic device and a second electronic device.

[0031] Specifically, the charging method includes: receiving device information from a first electronic device and a second electronic device respectively; determining a set of recommended values ​​based on the device information, the recommended values ​​including a wireless charging ratio recommended for the first electronic device and the second electronic device; and the wireless charging device transmitting wireless power to the first electronic device and the second electronic device according to the wireless charging ratio in the set of recommended values.

[0032] The wireless charging device sends a recommended value set to a first electronic device, causing the first electronic device to display the recommended value set. Further, the wireless charging device receives a priority from the first electronic device and calculates and determines a charging value set based on the priority. Determining the charging value set includes determining a wireless charging ratio allocated to both the first and second electronic devices. The wireless charging device then transmits wireless power to both the first and second electronic devices according to the determined wireless charging ratio in the recommended values.

[0033] Fourthly, this application also provides a charging method applied to a wireless charging device, wherein the wireless charging device can simultaneously provide wireless power to at least two devices being charged. The at least two devices being charged may include a first electronic device and a second electronic device, and the wireless charging device includes a display screen.

[0034] Specifically, the charging method includes: receiving device information from a first electronic device and a second electronic device respectively; determining a set of recommended values ​​based on the device information, the recommended values ​​including a wireless charging ratio recommended for the first electronic device and the second electronic device; and the wireless charging device transmitting wireless power to the first electronic device and the second electronic device according to the wireless charging ratio in the set of recommended values.

[0035] The wireless charging device displays an interface including a set of recommended values ​​and receives user input. If the user input indicates the determination of a wireless charging ratio to allocate to multiple electronic devices, the wireless charging device obtains a determined charging set and transmits wireless power to the first and second electronic devices according to the determined charging set. If the user input indicates the priority of the multiple electronic devices, the wireless charging device calculates a determined charging set based on the priority and transmits wireless power to the first and second electronic devices according to the determined charging set.

[0036] Fifthly, this application also provides a charging method that can be applied to a first electronic device, which is placed on a wireless charging device and receives wireless power from the wireless charging device.

[0037] Specifically, the method may include: receiving a set of recommended values ​​from a wireless charging device, the set of recommended values ​​including recommended wireless charging ratios allocated to a first electronic device and a second electronic device; displaying a first interface including the wireless charging ratios from the set of recommended values; generating a determined charging set in response to a first user action, the determined charging set including a determined wireless charging ratio allocated to the first electronic device and the second electronic device; and sending the determined charging set to the wireless charging device.

[0038] In one possible design of the fifth aspect, the above method may further include: a first interface including instruction information for prompting the user to set the priority of the device being charged; in response to a second operation by the user, determining the priority of the device being charged; and generating a determined charging set based on the priority.

[0039] In one possible design of the fifth aspect, the above method may further include: a first interface including instruction information for prompting the user to set the priority of the device being charged; in response to a second operation by the user, determining the priority of the device being charged; and sending the priority of the device being charged to the wireless charging device.

[0040] In another possible design approach in the fifth aspect, the above-mentioned priority-based generation of the charging set specifically includes:

[0041] Based on priority, the first recommended value of the first electronic device is increased, and a first determined charging value of the first electronic device is generated. The first recommended value is the wireless charging ratio recommended by the wireless charging device to be allocated to the first electronic device, and the first determined charging value is the wireless charging ratio determined to be allocated to the first electronic device.

[0042] Based on the priority reduction of the second recommended value of the second electronic device, a second determined charging value of the second electronic device is generated, wherein the second recommended value is the wireless charging ratio recommended by the wireless charging device to be allocated to the first electronic device, and the second determined charging value is the determined wireless charging ratio allocated to the first electronic device; a determined charging set is generated based on the first determined charging value and the second determined charging value.

[0043] In another possible design approach in the fifth aspect, the set of recommended values ​​includes a first recommended value for the first electronic device and a second recommended value for the second electronic device; the first recommended value is the wireless charging ratio recommended by the wireless charging device for the first electronic device, and the second recommended value is the wireless charging ratio recommended by the wireless charging device for the second electronic device.

[0044] In response to a user's first operation, a defined charging set is generated, specifically including: receiving a first defined charging value input by the user, wherein the first defined charging value is a wireless charging ratio determined for a first electronic device, and a second defined charging value is a wireless charging ratio determined for a second electronic device; modifying the second defined charging value based on the first defined charging value; and generating a defined charging set based on the first and second defined charging values.

[0045] In another possible design approach in the fifth aspect, the first electronic device includes a wireless charging application, the wireless charging application presets at least one charging scenario, the first charging scenario includes the first electronic device and the second electronic device, and determines the wireless charging ratio allocated to the first electronic device and the second electronic device.

[0046] The above method further includes: in response to the recommended value set including the wireless charging ratio of the first electronic device and the second electronic device, determining that the wireless charging device provides wireless power to the first electronic device and the second electronic device; and generating a determined charging set based on the first charging scenario.

[0068] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying 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 this embodiment, unless otherwise stated, "a plurality of" means two or more.

[0069] Taking WPT (Wireless Power Transmission) based on the principle of electromagnetic induction as an example, the wireless charging device includes multiple transmitting coils arranged in a preset stacking pattern, enabling the device to wirelessly charge electronic devices within a preset area. Due to its hardware design, the rated output power of the wireless charging device is fixed during wireless charging (e.g., 20W output power). When the wireless charging device provides wireless power to multiple electronic devices, the sum of the wireless charging power received by each device constitutes the rated output power of the wireless charging device.

[0070] For example, suppose the rated output power of the wireless charging device is 20W (watts), and a mobile phone is placed on the wireless charging device, causing the wireless charging device to provide wireless power to the mobile phone. If the rated charging power of the mobile phone is 10W, then the wireless charging device provides wireless charging power to the mobile phone according to the rated charging power of the mobile phone.

[0071] In this scenario, if the sum of the rated charging power of multiple electronic devices equals the rated output power of the wireless charging device, then the wireless charging device can provide the rated charging power to each electronic device. If the sum of the rated charging power of multiple electronic devices exceeds the rated output power of the wireless charging device, then the wireless charging device provides wireless charging power to the multiple electronic devices according to a preset power allocation principle. In this case, at least one electronic device will inevitably receive less wireless charging power than its rated charging power.

[0072] For example, assume the rated output power of the wireless charging device is 20W. If a first electronic device is near the wireless charging device, and its rated charging power is 20W, the wireless charging device provides 20W of wireless charging power to the first electronic device. If both the first and second electronic devices are near the wireless charging device, the second electronic device's rated charging power is 2W. The wireless charging device can simultaneously transmit wireless power to both the first and second electronic devices, and the sum of their rated charging power (i.e., 22W) is greater than the wireless charging device's rated output power (20W). In this case, the wireless charging device charges the first electronic device with 18W of output power and the second electronic device with 2W of output power according to a preset power allocation principle. The wireless charging power of the first electronic device is less than its rated charging power.

[0073] In some implementations, the wireless charging device is taken as an example as a wireless charging dock. The charging principle of a wireless charging dock is to calculate the charging time of multiple electronic devices and, as far as possible, meet the rated charging power of the electronic device with the shortest charging time.

[0074] Assuming both the phone and smart bracelet can receive wireless power transmission, and both are placed on a wireless charging dock with a rated charging power of 20W (dock, phone, and smart bracelet respectively), the dock calculates the possible charging times for both devices. Determining the smart bracelet's charging time is shorter, the dock charges it at 2W and the phone at 18W.

[0075] In other implementations, when a wireless charging dock provides wireless power to multiple devices, one of the devices can display the charging status of all devices, allowing the user to adjust the charging device based on the charging status.

[0076] For example, a mobile phone, smart bracelet, and tablet are all placed on a wireless charging dock. The phone can establish a communication connection with the smart bracelet via Bluetooth to obtain the smart bracelet's current battery level. Furthermore, the phone can also establish a communication connection with the tablet via Bluetooth to obtain the tablet's current battery level. In this way, the phone's display can show the current battery levels and wireless charging power of the smart bracelet and tablet. Users can view the current battery levels of the phone, smart bracelet, and tablet while checking the phone's interface, allowing them to monitor the charging status of any electronic device. If the user wants the tablet to charge faster, they can remove the phone from the wireless charging dock to increase the tablet's wireless charging power. This ensures the tablet's wireless charging power reaches its rated charging power, allowing it to charge more quickly.

[0077] In this implementation, users can adjust the charging status of multiple electronic devices based on their viewing status. However, if a user wants to prioritize charging a particular electronic device, they need to monitor its charging status and manually adjust the charging status, resulting in a poor user experience.

[0078] Based on the above implementation method, it can be determined that when a wireless charging device simultaneously provides wireless charging for multiple electronic devices, if the sum of the rated charging power of the multiple electronic devices is greater than the rated output power of the wireless charging device, the wireless charging device can allocate wireless charging power to the multiple electronic devices according to a preset allocation method (or algorithm). In other words, the wireless charging device can wirelessly charge multiple electronic devices without interacting with the user.

[0079] In this situation, the wireless charging device cannot allocate the rated charging power according to the user's needs. For example, among multiple electronic devices, the user may want to prioritize charging the first electronic device, meaning the wireless charging device needs to allocate more wireless power to the first electronic device to shorten its charging time. Since the wireless charging device cannot interact with the user, it cannot obtain the user's needs and therefore cannot meet them.

[0080] This application provides a charging method applicable to wireless charging devices. When the wireless charging device uses the method provided in this application, it can interact with the user and obtain user requests during the wireless charging process for at least two electronic devices. In this way, the wireless charging device can allocate the rated wireless charging power to the at least two electronic devices according to the user's needs.

[0081] The charging method provided in the embodiments of this application will be described below in conjunction with application scenarios.

[0082] The method provided in this application can be applied to wireless charging scenarios. Here, we take the scenario where a wireless charging device provides wireless power to a mobile phone, smart bracelet, and tablet as an example. Please refer to... Figure 1A This is a schematic diagram of a wireless charging scenario provided in an embodiment of this application. Figure 1A As shown, a mobile phone 200, a smart bracelet 300, and a tablet computer 400 are placed on a wireless charging device 100. The wireless charging device 100 provides wireless power to the mobile phone 200, smart bracelet 300, and tablet computer 400. The rated wireless charging power of the wireless charging device 100 is 20W, the rated charging power of the mobile phone 200 is 20W, the rated charging power of the smart bracelet 300 is 2W, and the rated charging power of the tablet computer 400 is 20W.

[0083] For example, suppose the wireless charging device 100 does not have a display screen. The wireless charging device 100 identifies a mobile phone 200, a smart bracelet 300, and a tablet computer 400, and determines that all three devices include a display screen. The wireless charging device 100 interacts with the user via the display screen of the mobile phone 200. For instance, the wireless charging device 100 sends a prompt message to the mobile phone, asking the user whether to set a device to be charged first. The device to be charged first is the one allocated more charging power, i.e., the electronic device the user wants to charge as quickly as possible.

[0084] Mobile phone 200 receives and displays a notification from wireless charging device 100. Please refer to [the website / company name]. Figure 1B This is a diagram illustrating the notification message interface displayed on a mobile phone. For example... Figure 1BAs shown in (a), the display screen of mobile phone 200 shows the prompt message: "Do you want to set the device to be charged first?", and the corresponding options "Yes" and "No". When the user wants wireless charging device 100 to prioritize charging mobile phone 200, the user clicks as shown in (a). Figure 1B The "Yes" option in the prompt interface (a) is shown.

[0085] When the phone receives a click from the user on the "Yes" option, the phone displays the following: Figure 1B The interface shown in (b) includes icons for mobile phone 200, smart bracelet 300, and tablet computer 400. If mobile phone 200 receives a click operation from the user on the icon corresponding to mobile phone 200, it determines that the user wants to set mobile phone 200 as the device to be charged first. In this way, mobile phone 200 can send a message to wireless charging device 100 to prioritize charging mobile phone 200. Upon receiving the message from mobile phone 200, wireless charging device 100, in response to the message, prioritizes charging mobile phone 200.

[0086] If the wireless charging device 100 has a display screen, it can display prompts and receive user input. If the user input instructs that the mobile phone 200 should be charged first, the wireless charging device 100 sets the mobile phone 200 as the device to be charged first in response to the user input.

[0087] Understandably, in the above example, the wireless charging device 100 can also use the display screen of the tablet computer 400 to display prompts and interact with the user through the tablet computer 400.

[0088] For example, a wireless charging application is installed on the mobile phone 200. The wireless charging application is used to set the charging method of the wireless charging device 100. When the wireless charging device 100 provides wireless power to the mobile phone 200, the wireless charging dock 100 can provide wireless power to the mobile phone 200 according to the charging method in the wireless charging application.

[0089] For example, the first charging method in a wireless charging application is as follows: when the wireless charging device 100 simultaneously wirelessly charges the mobile phone 200, the smart bracelet 300, and the tablet computer 400, the wireless charging device 100 is set to allocate 60% of the wireless charging power to the mobile phone 200, 10% of the wireless charging power to the smart bracelet 300, and 30% of the wireless charging power to the tablet computer.

[0090] When a mobile phone 200, a smart bracelet 300, and a tablet computer 400 are placed on a wireless charging dock, the wireless charging device 100 establishes a communication connection with the mobile phone 200. The mobile phone 200 runs a wireless charging application and sends a first charging method to the wireless charging device 100. The wireless charging device 100 receives the first charging method from the mobile phone 200, determines that the current charging scenario is the scenario for the first charging method, and then wirelessly charges the mobile phone 200, smart bracelet 300, and tablet computer 400 according to the first charging method. Specifically, the wireless charging device 100 provides 12W of wireless charging power to the mobile phone 200, 2W of wireless charging power to the smart bracelet 300, and 6W of wireless charging power to the tablet computer 400.

[0091] The embodiments of this application will now be described in conjunction with the accompanying drawings.

Figure 2 As shown, the wireless charging device 100 may include: a processor 110, an internal memory 121, a button 130, a wireless charging transmitter 150, and a wireless communication unit 160. The wireless charging transmitter 150 includes a transmitting coil.

[0093] It is understood that the structures illustrated in the embodiments of the present invention do not constitute a specific limitation on the wireless charging device 100. In other embodiments of this application, the wireless charging device 100 may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0094] In some implementations, the wireless charging device 100 may include a display screen (or touchscreen) for displaying prompts and acquiring user operation information to enable interaction with the user through the display screen.

[0096] Processor 110 may include one or more processing units, such as a controller, memory, modem, etc. Different processing units may be independent devices or integrated into one or more processors. The controller in processor 110 may serve as the central nervous system and command center of the wireless charging device 100. The controller can generate operation control signals based on instruction opcodes and timing signals to control instruction fetching and execution.

[0097] In some implementations, when the wireless charging device 100 wirelessly charges multiple electronic devices, the controller can allocate the rated charging power according to a preset algorithm to achieve simultaneous wireless charging of multiple electronic devices.

[0098] The processor 110 may also include a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. This memory can store instructions or data that the processor 110 has just used or that are used repeatedly. If the processor 110 needs to use the instruction or data again, it can retrieve it directly from the memory. This avoids repeated accesses, reduces the waiting time of the processor 110, and thus improves the efficiency of the system.

[0099] In some embodiments, processor 110 may include one or more interfaces. These interfaces are used to couple internal memory 121, wireless charging transmitter 150, and wireless communication unit 160, etc.

The wireless charging transmitter 150 is connected to an alternating current (AC) voltage. The rectifier circuit 151 converts the AC voltage to a direct current (DC) voltage, and the inverter circuit 152 converts the DC voltage to high-frequency AC. The resonant circuit 153 receives the AC voltage output from the inverter circuit and transmits it to the transmitting coil 154, generating an alternating current in the transmitting coil, causing the wireless charging transmitter 150 to form a changing magnetic field (or alternating magnetic field). In some implementations, the wireless charging transmitter 150 may include one or N transmitting coils 154, where N is a positive integer greater than 1.

[0102] The wireless communication module 160 can provide solutions for wireless communication applications such as wireless local area networks (WLAN), Bluetooth (BT), global navigation satellite system (GNSS), near field communication (NFC), and infrared (IR) technology for use in the wireless charging device 100.

[0105] It is understood that the structures illustrated in the embodiments of the present invention do not constitute a specific limitation on the electronic device 500. In other embodiments of this application, the electronic device 500 may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0106] Processor 510 may include one or more processing units, such as application processors (APs), modem processors, graphics processing units (GPUs), image signal processors (ISPs), controllers, memory, video codecs, digital signal processors (DSPs), baseband processors, and neural network processing units (NPUs). These different processing units may be independent devices or integrated into one or more processors.

[0107] The controller can be the nerve center and command center of the electronic device 500. The controller can generate operation control signals based on the instruction opcode and timing signals to control the fetching and execution of instructions.

[0108] The processor 510 may also include a memory for storing instructions and data. In some embodiments, the memory in the processor 510 is a cache memory. This memory can store instructions or data that the processor 510 has just used or that are used repeatedly. If the processor 510 needs to use the instruction or data again, it can directly retrieve it from the memory. This avoids repeated accesses, reduces the waiting time of the processor 510, and thus improves the efficiency of the system.

[0109] In some embodiments, processor 510 may include one or more interfaces.

[0110] It is understood that the interface connection relationships between the modules illustrated in the embodiments of the present invention are merely illustrative and do not constitute a structural limitation on the electronic device 500. In other embodiments of this application, the electronic device 500 may also employ different interface connection methods or combinations of multiple interface connection methods as described in the above embodiments.

[0111] The external storage interface 520 can be used to connect an external memory card, such as a Micro SD card, to expand the storage capacity of the electronic device 500. The external memory card communicates with the processor 510 through the external storage interface 520 to perform data storage functions. For example, music, video, and other files can be saved on the external memory card.

[0112] Internal memory 521 can be used to store computer executable program code, which includes instructions.

The program storage area may store the operating system, at least one application program required for a function (such as sound playback, image playback, etc.), etc. The data storage area may store data created during the use of electronic device 500 (such as audio data, phonebook, etc.). Furthermore, internal memory 521 may include high-speed random access memory and may also include non-volatile memory, such as at least one disk storage device, flash memory device, universal flash storage (UFS), etc.

[0113] The charging management module 540 receives charging input from a charger, which can be either a wireless charger or a wired charger. The power management module 541 connects the battery 542 and the wireless charging receiver 543, and the charging management module 540 is connected to the processor 510. The power management module 541 receives input from the battery 542, the charging management module 540, or the wireless charging receiver 543, and supplies power to the processor 510, internal memory 520, external memory 521, display screen 560, and sensor module 580, etc.

[0114] The wireless charging receiver 543 includes a receiving coil 544, a resonant circuit 545, and a rectifier circuit 546. When the electronic device 500 is in an alternating magnetic field, the receiving coil 544 obtains a high-frequency AC voltage through electromagnetic induction and transmits this high-frequency AC voltage to the resonant circuit 545. The resonant circuit 545 outputs a resonant high-frequency AC power, and the rectifier circuit 546 rectifies the resonant high-frequency AC power into direct current, which is then used by the electronic device 500.

[0115] Electronic device 500 implements display functions through a GPU, display screen 560, and application processor. The GPU is a microprocessor for image processing, connected to the display screen 560 and the application processor. The GPU performs mathematical and geometric calculations and is used for graphics rendering. Processor 510 may include one or more GPUs, which execute program instructions to generate or modify display information.

[0116] Display screen 560 is used to display images, videos, etc. Display screen 560 includes a display panel. The display panel may be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a miniature LED, a microLED, a quantum dot light-emitting diode (QLED), etc. In some embodiments, electronic device 500 may include one or N displays 560, where N is a positive integer greater than 1.

[0117] Button 530 may include a power button, volume buttons, zoom buttons, etc. Button 530 can be a mechanical button or a touch-sensitive button.

[0118] It should be noted that the electronic device 500 in this application embodiment can be a mobile phone, digital camera, camcorder, smartwatch, tablet computer, desktop computer, laptop computer, handheld computer, notebook computer, dashcam, ultra-mobile personal computer (UMPC), netbook, and cellular phone, etc. Additionally, the electronic device can also be an in-vehicle computer, personal digital assistant (PDA), augmented reality (AR) / virtual reality (VR) device, etc. This application embodiment does not impose any special limitations on the specific form of the electronic device.

[0119] The following will provide a detailed description of the wireless power transmission process of the wireless charging device 100 and the electronic device 500.

[0120] The wireless charging device 100 includes a transmitting coil, and the electronic device 500 includes a receiving coil. The transmitting coil can generate an alternating magnetic field. When the electronic device 500 is located in the alternating magnetic field generated by the transmitting coil, the receiving coil will generate an induced current in the alternating magnetic field. This achieves the purpose of the wireless charging device 100 transmitting wireless power to the electronic device 500.

[0121] Specifically, the wireless charging device 100 and the electronic device 500 transmit wireless power based on the Qi protocol. Please refer to [reference needed]. Figure 4 This is a flowchart illustrating wireless power transmission between a wireless charging device 100 and an electronic device 500. (See attached diagram.) Figure 4 As shown, the wireless power transmission process includes steps 401-408.

[0122] Step 401: Wireless charging device transmits power detection broadcast to detect devices receiving wireless power.

[0123] The wireless charging device 100 can periodically transmit power detection broadcasts, such as every 30 seconds, 1 minute, 3 minutes, or 5 minutes. If the power detection broadcast is received, the wireless charging device can determine that there is a device receiving wireless power within the wireless charging range.

[0124] For example, the wireless charging device 100 is configured to broadcast a power detection signal every 400 ms.

[0125] It is understandable that the wireless charging device 100 transmit power detection broadcast can be understood as the selection phase of the wireless charging device 100.

[0126] When electronic device 500 approaches wireless charging device 100, wireless charging device 100 transmits a power detection broadcast. Electronic device 500 receives the power detection broadcast transmitted by wireless charging device 100, causing wireless charging device 100 to select electronic device 500 and transmit power to electronic device 500.

[0127] It should be noted that the function of the wireless charging device 100 during the selection phase is to detect whether there is a device receiving wireless power within the wireless charging range. The wireless charging device 100 transmits a power detection broadcast (or can be understood as an energy signal) and detects the current value flowing through the transmitting coil. If there is no device receiving wireless power within the wireless charging range, the current value in the transmitting coil is at its maximum. When an electronic device 500 is present within the wireless charging range, the wireless charging device 100 can detect a decrease in the current value of the transmitting coil. Thus, the wireless charging device 100 determines that an electronic device 500 is present within the wireless charging range and transmits power to the electronic device 500.

[0128] Step 402: The wireless charging device transmits power to the electronic device.

[0129] If the wireless charging device 100 determines the power to transmit to the electronic device 500 during the selection phase, then the wireless charging device 100 can continuously transmit power to the electronic device 500.

[0130] Step 403: The electronic device sends a signal strength identification packet to the wireless charging device according to the Qi protocol.

[0131] Among them, the signal strength packet (SS packet) represents the strength of the energy picked up by the electronic device 500 (the device that receives wireless power).

[0132] Step 404: The wireless charging device receives an SS packet that meets the correct timing requirements.

[0133] Steps 402-404 above are referred to as the ping phase (or handshake phase) of the Qi protocol. The electronic device sends power strength data packets according to the Qi protocol. After the wireless charging device receives the Qi protocol power strength data packets, it can enter the power transmission identification and configuration phase.

[0134] For example, when the wireless charging device 100 continuously transmits power to the electronic device 500, after a preset time, the wireless charging device 100 receives the start bit of the SS packet, and the SS packet is correctly received by the wireless charging device 100. Then the wireless charging device 100 enters the next stage of Qi charging. If the wireless charging device 100 does not receive the start bit of the SS packet within the preset time, the wireless charging device repeats the above selection stage (i.e., step 401).

[0135] Step 405: The electronic device sends an identification packet and a configuration packet to the wireless charging device in sequence.

[0136] The identification packet (ID) may include information such as the version information, manufacturer code, and device code of the electronic device 500, enabling the wireless charging device 100 to identify the electronic device 500.

[0137] The configuration packet (CP) can include information such as the maximum power and power level of the electronic device 500, so that the wireless charging device 100 can be configured with wireless charging power according to the CP packet.

[0138] Step 406: The wireless charging device receives the ID packet and CP packet from the electronic device in sequence and establishes a power transfer protocol.

[0139] Steps 405 and 406 constitute the identification and configuration phase of wireless power transmission. During this phase, the wireless charging device needs to identify the electronic device and collect its configuration information. Therefore, the wireless charging device needs to receive the ID packet and CP packet defined by the Qi protocol. This includes identifying data packets, extending the identification data packet duration, delaying the power control data packet duration, and configuring the configuration data packet.

[0140] For example, after receiving the SS packet, the wireless charging device 100 receives the start bit of the ID packet within a preset time period, thus confirming that the wireless charging device has received the ID packet. After receiving the end bit of the ID packet, the wireless charging device 100 receives the start bit of the CP packet within a preset time period. That is, when the wireless charging device 100 confirms that it has correctly received the ID packet and the CP packet, the wireless charging device 100 can create power transmission parameters based on the information in the CP packet and enter the power transmission phase.

[0141] If the wireless charging device 100 receives the SS packet but does not receive the start bit of the ID packet after a preset time period; or if the wireless charging device 100 receives the start bit of the ID packet but does not receive the start bit of the CP packet within a preset time period after the ID packet transmission is completed, then the wireless charging device 100 may stop transmitting power to the electronic device 500.

[0142] If the wireless charging device 100 receives the ID packet and CP packet in the wrong order, or if the contents of the ID packet and CP packet are incorrect, the wireless charging device 100 may stop transmitting power to the electronic device 500.

[0143] Step 407: The wireless charging device dynamically adjusts the transmission power according to the power required by the power transmission protocol using proportional-integral-derivative (PID) methods.

[0144] The wireless charging device 100 can dynamically adjust its transmission power using proportional-integration-differential (PID) based on the acquired CP packet, so that the transmission power of the wireless charging device can meet the charging requirements of the electronic device 500.

[0145] Step 408: The electronic device sends CE packets, RP packets, and EPT packets to the wireless charging device.

[0146] Steps 407 and 408 constitute the power transmission phase of the wireless transmission device. The wireless charging device 100 can provide wireless power according to the charging requirements of the electronic device 500. If the wireless charging device 100 detects an abnormal value, it stops transmitting power and returns to the selection phase (i.e., step 401). Abnormal values ​​include, but are not limited to, abnormal transmission power and abnormal power values ​​received by the electronic device.

[0147] Understandably, during the power transfer phase, the 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.

[0148] The CE package includes control error values, which reflect the magnitude of control error in the wireless charging device and are input parameters of the controller in the wireless charging device 100.

[0149] The RP packet includes the received power value of electronic device 500, which reflects the power received by electronic device 500.

[0150] The EPT packet includes a termination code, which indicates the reason for terminating power transfer. For example, a termination code of 0x01 indicates that power transfer is terminated because charging is complete; a termination code of 0x03 indicates that power transfer is terminated because of overheating, etc. The termination code can be one defined in the Qi protocol.

[0151] For example, 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. After receiving the start bit of the CE packet, it receives the start bit of the RP packet within a preset time period and correctly receives the RP packet. The wireless charging device 100 continuously transmits power to the electronic device 500. When the wireless charging device 100 receives an EPT packet from the electronic device 500, it stops transmitting power to the electronic device 500.

[0152] If the wireless charging device 100 receives the CP packet but does not receive the start bit of the CE packet within a preset time after receiving the CP packet, the wireless charging device 100 will stop transmitting power to the electronic device 500.

[0153] If the wireless charging device 100 receives the start bit of the CE packet but does not receive the start bit of the RP packet within a preset time period, the wireless charging device 100 will stop transmitting power to the electronic device 500.

[0154] The charging method provided in the embodiments of this application will be described below.

[0155] This application uses a wireless charging dock as an example of a wireless charging device, and the electronic devices include: a mobile phone, a smart bracelet, and a tablet computer. The charging method provided by this application is described in the scenario where the wireless charging dock simultaneously provides wireless power to a mobile phone, a smart bracelet, and a tablet computer.

[0156] Example 1

[0157] A mobile phone, smart bracelet, and tablet can be placed simultaneously on a wireless charging dock, allowing the dock to provide wireless power to all three devices at the same time. The mobile phone, smart bracelet, and tablet are referred to as the devices being charged.

[0158] Please refer to Figure 5 The above describes a charging method provided in an embodiment of the application. The charging method includes steps 501-508.

[0159] Step 501: During the wireless charging identification and configuration phase, send device information to the wireless dock, including the device model.

[0160] The mobile phone, smart bracelet, and tablet each send device information to the wireless charging dock. This device information may include the device model, hardware structure, and other details. The data format of the device information can be an agreed-upon format with the wireless charging dock, allowing the dock to recognize the corresponding device information.

[0161] In some implementations, if the wireless charging dock does not receive device information from the electronic device (i.e., mobile phone, smart bracelet, or tablet) during the wireless charging identification and configuration phase, the wireless charging dock can establish a communication connection with the electronic device (taking a mobile phone as an example). For instance, after establishing a communication connection with the mobile phone, the wireless charging dock can request the mobile phone to send device information, and the mobile phone responds to the request by sending the device information back to the wireless charging dock.

[0162] Since the phone is wirelessly charging, the distance between the phone and the wireless charging pad is relatively short. Therefore, the wireless charging pad and the phone can establish a communication connection using short-range communication methods such as Bluetooth, NFC, or WLAN.

[0163] Step 502: The wireless charging dock identifies the corresponding device model of the mobile phone, smart bracelet and tablet based on the device information.

[0164] For example, device information may include the device model. For instance, a mobile phone's device information might include the brand and model number. The wireless charging dock can determine relevant information about the mobile phone based on the device model, such as the phone's hardware information, the types of sensors it contains, and the short-range communication methods it supports.

[0165] As another example, the device information may also include the device type. For instance, if the device information sent by the mobile phone to the wireless charging dock includes the mobile phone, then the wireless charging dock can determine that it provides wireless power to the mobile phone.

[0166] In some implementations, wireless charging docks can interact with remote devices (such as servers, cloud devices, etc.) to obtain relevant information about the phone based on the device signal. For example, the device information might indicate that the phone is a specific brand and model. The wireless charging dock interacts with a server to query the hardware information corresponding to the specific brand and model. Based on the hardware information sent by the server, the wireless charging dock can determine whether the phone supports near-field communication (NFC), the phone's screen size, and other information.

[0167] In other implementations, the wireless charging dock can be pre-set with the phone's hardware information. When the wireless charging dock receives the device information sent by the phone, it can determine the phone's hardware information by querying the pre-set information.

[0168] It should be noted that the wireless charging dock can have a pre-set private protocol with the device being charged (phone, smart bracelet, and tablet). This private protocol specifies the information format for the phone type. For example, the private protocol specifies that a data string composed of 0s and 1s represents device information. When the wireless charging dock receives the device information composed of a data string of 0s and 1s, it determines the device model of the device being charged based on this device information. For example, 0101 indicates that the device type is a model 1 phone.

[0169] In some implementations, the wireless charging dock can have a preset device model lookup table, which allows the wireless charging dock to determine the device model of the device being charged based on the device information composed of data strings of 0s and 1s from the device being charged.

[0170]

[0171] Step 503: The wireless charging dock and the mobile phone establish a communication connection.

[0172] Understandably, if a wireless charging dock chooses to interact with the user via a mobile phone, a communication connection is established between the wireless charging dock and the mobile phone. This allows the wireless charging dock to send prompts to the mobile phone, and the mobile phone can send information corresponding to the user's actions back to the wireless charging dock, thus achieving the technical purpose of interaction between the wireless charging dock and the user.

[0173] It should be noted that this example uses a wireless charging dock to interact with a mobile phone. In practical applications, the wireless charging dock can also interact with a tablet computer. In other application scenarios, the wireless charging dock can select the appropriate device to be charged based on the model of the device being charged for interaction with the user.

[0174] It's worth noting that in some wireless charging scenarios, assuming the wireless charging dock is a laptop, and the laptop provides wireless power to the phone and smartwatch, the laptop doesn't need to interact with the device being charged. Instead, the laptop can interact with the user using its own external devices (such as a monitor, keyboard, and mouse).

[0175] For example, when the wireless charging dock receives device information from all the devices being charged, it determines the wireless charging ratio for each device. These wireless charging ratios are combined into a recommended set of values, which is the wireless charging dock's recommendation for assigning a wireless charging pad to each device being charged.

[0176] The wireless charging dock provides a wireless charging rate for each device being charged, based on a set of recommended values.

[0177] Step 504: The wireless charging dock sends a notification message to the phone, which prompts the user whether to set the device to be charged first.

[0178] Among them, the devices that are given priority for charging are those that are allocated more charging power.

[0179] Understandably, the device that users want charged first is the one they want to finish charging as quickly as possible. Therefore, providing power to the device being charged first, according to its rated charging power, can effectively shorten its charging time. If it is not possible to provide the rated charging power to the device being charged first, then the power ratio of the device being charged first should be increased.

[0180] It should be noted that the wireless charging dock can interact with the user through the electronic device being wirelessly charged to determine the device to be charged first in the current charging scenario. The device information obtained by the wireless charging dock helps it determine the device to use for user interaction.

[0181] In some implementations, the wireless charging dock is configured to allow user interaction via a device with a larger touchscreen (or display). For example, when a mobile phone, smart bracelet, and tablet are all wirelessly charging, the wireless charging dock determines that the tablet's display is larger based on device information, establishes a communication connection with the tablet, and allows the tablet to interact with the user.

[0182] In other implementations, the wireless charging dock can also be configured for voice interaction. For example, the wireless charging dock can simultaneously provide wireless power to a smart bracelet, a smart speaker, and a tablet, while the dock receives information from the devices. In some cases, the wireless charging dock uses a smart speaker to interact with the user via voice.

[0183] In other implementations, the wireless charging dock can be configured to prioritize user interaction via the phone when wirelessly charging. In the charging scenario provided in this application embodiment, the wireless charging dock receives device information from the phone, smart bracelet, and tablet. The wireless charging dock determines that user interaction will be via the phone.

[0184] Step 505: The mobile phone receives a prompt message from the wireless charging dock and displays the prompt message.

[0185] The prompt information may include the wireless charging ratio from the recommended value set.

[0186] For example, the prompt message might be: "Do you want to set the device to be charged first?" Figure 1B As shown in (a), the mobile phone displays the notification message, allowing the user to access it via their phone. Furthermore, as... Figure 1B The interface shown in (a) also includes a description of the devices that are prioritized for charging, such as "The devices that are prioritized for charging are those that are allocated more charging power".

[0187] In some implementations, the phone displays this prompt message, and if the phone does not receive any user interaction after a preset time, the phone can assume that the user does not need to set a priority charging device.

[0188] Step 506: In response to the interaction with the user, determine that the mobile phone is the device to be charged first.

[0189] Among them, the mobile phone displays as follows Figure 1B The interface for the prompt information shown in (b) includes the device identifiers for the mobile phone, smart bracelet, and tablet. The mobile phone can obtain the user's... Figure 1B Clicking on the device identifier in the main interface shown in (b) is used to determine the device to be charged first.

[0190] For example, the mobile phone receives the user's... Figure 1B Clicking the device icon on the main interface shown in (b) confirms that the phone is the device to be charged first.

[0191] For example, a mobile phone can receive user requests. Figure 1B In the main interface shown in (b), the phone's device identifier is displayed, and the phone also receives a click operation from the user on the smart bracelet's device identifier. In this case, the phone can be identified as the device to be charged first. When the wireless charging dock determines that the phone has finished charging, the wireless charging dock determines that the smart bracelet is the device to be charged first.

[0192] Understandably, during the interaction between the phone and the user, the user can set the devices to be charged first via their phone. Furthermore, the user can also set the wireless charging power for each device via their phone. The wireless charging dock identifies the device model being charged, and can determine the charging power for that device based on its model (e.g., a recommended set of values).

[0193] For example, the wireless charging dock sends a recommended value (e.g., a first recommended value or a second recommended value) for each device being charged to the phone. The phone displays a set of recommended values, allowing the user to view this set of values ​​for the devices being charged. When the user views the set of recommended values ​​displayed on the phone, if the user wants to charge the devices according to the recommended values ​​in the set, they can interact with the phone to determine the wireless charging power to be provided to the devices according to the wireless charging ratio in the set. If the user does not want to provide wireless charging power to the devices according to the set of recommended values ​​displayed on the phone, they can interact with the phone to input the wireless charging ratio of the devices being charged (determining the charging value). The phone then sends the user-input wireless charging ratio (or determined charging set) to the wireless charging dock, which can then provide wireless charging power to the devices according to the user-input wireless charging ratio (determined charging set).

[0194] In this process, the mobile phone receives a confirmed charging value input by the user. For example, a first electronic device corresponds to a first confirmed charging value, and a second electronic device corresponds to a second confirmed charging value. The mobile phone determines the charging set based on the user's operation and sends the confirmed charging set to the wireless charging dock.

[0195] In the first implementation, the phone displays as follows: Figure 6A The interface showing the prompt message in (a) indicates that the mobile phone has received a click from the user on the device identifier of the mobile phone, such as... Figure 6A In (a) the phone's device identifier is marked, indicating that the phone is identified as the device to be charged first. For example, the phone receives a click operation from the user on the phone's device identifier, thus identifying the phone as the device to be charged first.

[0196] In response to receiving a selection of the device to be charged first, the phone displays as follows: Figure 6A The power configuration interface is shown in (b). The wireless charging dock sends a set of recommended values ​​to the phone, and the power configuration interface also includes this set of recommended values. Figure 6AThe power configuration interface shown in (b) includes a power configuration item 61 for a mobile phone, a power configuration item 62 for a smart bracelet, and a power configuration item 63 for a tablet computer. Each power configuration item also includes a recommended value. For the mobile phone power configuration item 61, the recommended value is 70, meaning 70% of the wireless charging dock's rated output power is transmitted to the mobile phone. For the smart bracelet power configuration item 62, the recommended value is 10, meaning 10% of the wireless charging dock's output power is transmitted to the smart bracelet. For the tablet computer power configuration item 63, the recommended value is 20, meaning 20% ​​of the wireless charging dock's output power is transmitted to the tablet computer.

[0197] Understandably, each power configuration item also corresponds to a recommended power range. For example, the recommended power range for power configuration item 61 on a mobile phone is 0-70. When the mobile phone receives the user's power setting, such as... Figure 6A As shown in (c), the mobile phone receives a charging power of 65 kW as set by the user.

[0198] For example, when a mobile phone receives a power setting for the device being charged, the recommended value will not be displayed for that device's power setting. Figure 6A In the interface shown in (c), the mobile phone receives the power configured by the user, and the charging power allocated to the mobile phone is 65% (e.g., referred to as the first determined charging value), the charging power allocated to the smart bracelet is 10% (e.g., referred to as the second determined charging value), and the charging power allocated to the tablet is 20% (e.g., referred to as the third determined charging value).

[0199] In the second implementation, when the wireless charging dock provides wireless power to mobile phones, smart bracelets, and tablets, the dock can determine the charging priority order of the devices. When the wireless charging dock sends a notification to the phone, this notification includes the charging priority order of the devices, allowing the user to understand the charging priority order through the interface displayed on the phone.

[0200] like Figure 6B As shown in (a), this is the notification message interface displayed on the mobile phone. Among them, as... Figure 6B In (a), the priority charging order in the prompt message is: 1. Mobile phone, 2. Tablet, 3. Smart bracelet. The prompt message specifically asks "Do you want to adjust the charging order of the devices being charged?" (i.e., set the priority of the devices being charged).

[0201] If the phone receives a click from the user on an adjustment option, it will display something like this. Figure 6B The interface for selecting the charging order (i.e., priority) of the devices being charged is shown in (b). If the phone receives a click from the user indicating that the option should not be adjusted, the phone will not display a prompt message. For example, if the phone receives a click from the user indicating that the option should be adjusted... Figure 6B The interface shown in (b) includes device identifiers for the mobile phone, smart bracelet, and tablet. When the mobile phone first receives a user's selection of a device identifier, that identifier is marked as 1. Figure 6B As shown in (b), the device identifier of the mobile phone is marked as 1, the device identifier of the smart bracelet is marked as 2, and the device identifier of the tablet computer is marked as 3.

[0202] For example, when the mobile phone determines the charging order of the devices being charged, the mobile phone can set the charging power according to the charging order (i.e., priority) and provide wireless charging rates to the mobile phone, smart bracelet and tablet in sequence according to the charging priority.

[0203] For example, a wireless charging dock provides a 70% wireless charging rate for a mobile phone, a 10% wireless charging rate for a smart bracelet, and a 20% wireless charging rate for a tablet. The phone is considered fully charged when its battery reaches 100%. Furthermore, the wireless charging dock provides a 20% wireless charging rate (where the smart bracelet's rated charging power is 20% of the wireless charging dock's output power) for the smart bracelet and an 80% wireless charging rate for the tablet. The smart bracelet is considered fully charged when its battery reaches 100%. The wireless charging dock can provide wireless power to the tablet according to its rated charging power.

[0204] For example, when a mobile phone determines the priority of the device being charged, the phone can display something like this: Figure 6B The power configuration interface is shown in (c). The mobile phone can receive the power settings of multiple devices being charged from the user and provide a wireless charging ratio to the devices being charged according to the set charging power.

[0205] like Figure 6B The power allocation interface shown in (c) includes power configuration items for the device being charged, recommended power values, etc. It should be noted that... Figure 6B The interface shown in (c) is similar to the one described above. Figure 6A The interface shown in (b) is the same, for example... Figure 6B The operation of the power allocation interface shown in (c) is similar to that of the above-mentioned... Figure 6A The interface operation shown in (b) is the same, and will not be described again here.

[0206] In the third implementation, the wireless charging dock sends a prompt message to the phone, indicating whether to configure charging power for multiple devices being charged. For example... Figure 6CAs shown in (a), the mobile phone displays a prompt interface, which includes a prompt message. The prompt interface also includes option controls: a "Yes" option control and a "No" option control. The prompt interface also includes operation prompts for each option control.

[0207] Specifically, if the phone receives a click from the user on the "Yes" option control, in response to that click, the phone displays as follows: Figure 6C The power allocation interface is shown in (b). If the phone receives a click on the "No" option control from the user, in response to the click, the phone allocates wireless charging ratios to multiple devices being charged according to the preset charging power allocation rules.

[0208] It's worth mentioning that when the phone displays the power allocation interface (i.e., as shown in the image)... Figure 6A The interface shown in (b) is as follows: Figure 6B The interface shown in (c) and as shown in Figure 6C The interface shown in (b) includes a set of recommended power values ​​for each device being charged, which are set by the wireless charging dock.

[0209] The following will explain the principle by which a wireless charging dock distributes charging power to the device being charged.

[0210] The wireless charging dock has a preset charging power allocation rule. When the wireless charging dock determines that there are multiple devices being charged, and the sum of the rated charging power of these devices is greater than the rated output power of the wireless charging dock, the wireless charging dock allocates charging power to the multiple devices according to the preset charging power allocation rule to obtain a recommended set of values.

[0211] For example, the wireless charging dock can categorize the devices being charged into multiple classes based on their rated charging power. Taking three categories as an example, mobile phones, tablets, and laptops could be categorized as Class 1 devices; headphones and watches as Class 2 devices; and VR glasses and electronic rings as Class 3 devices.

[0212] The charging rules may also include: when only devices of the same type (e.g., the first type of devices) are placed on the wireless charging base, the wireless charging base allocates charging power to the multiple devices according to the ratio of their rated charging power.

[0213] For example, mobile phone 1, mobile phone 2, and tablet are placed on a wireless charging dock. Mobile phone 1 has a rated charging power of 10W, mobile phone 2 has a rated charging power of 10W, and tablet has a rated charging power of 15W. The wireless charging dock sets the ratio of the rated charging power of each device to 2:2:3. The rated output power of the wireless charging dock is 20W. Therefore, the wireless charging rate transmitted from the wireless charging dock to mobile phone 1 is 5.7W, the wireless charging rate transmitted from the wireless charging dock to mobile phone 2 is 5.7W, and the wireless charging rate transmitted from the wireless charging dock to tablet is 8.6W.

[0214] When the wireless charging dock determines that there is at least one type of device to be charged, the wireless charging dock allocates charging power to each type of device according to a preset ratio. For example, if the devices to be charged on the wireless charging dock include a first type and a second type, then the first type of device is allocated 70% of the wireless charging power, and the second type is allocated 30%. Alternatively, if the devices to be charged on the wireless charging dock include a first type, a second type, and a third type, then the first type is allocated 50% of the wireless charging power, the second type 30%, and the third type 20%.

[0215] If the device being charged includes more than one electronic device, the wireless charging ratio can be allocated according to the rated charging ratio of the multiple electronic devices.

[0216] It is worth mentioning that the percentage of wireless charging ratio allocated in the above example is just an example, and the specific value can be set according to the actual situation.

[0217] For example, a wireless charging dock provides wireless charging rates for mobile phones, tablets, and smart bracelets. Since mobile phones and tablets are classified as Class 1 charging devices, and smart bracelets as Class 2 charging devices, taking a wireless charging dock with a rated output power of 20W as an example, mobile phones and tablets are allocated 70% (14W) of the wireless charging rate, and smart bracelets are allocated 30% (6W). Since the rated charging power of the smart bracelet is 2W, this means the wireless charging dock can only allocate a maximum of 10% (2W) of the wireless charging rate to the smart bracelet. Therefore, the wireless charging dock can adjust the power allocation to allocate 90% of the wireless charging rate to mobile phones and tablets, and 10% to the smart bracelet.

[0218] For example, when a mobile phone and a smartwatch are placed on a wireless charging dock, the dock identifies the models of the devices being charged (i.e., the phone and smartwatch). Based on preset wireless power allocation rules, the dock can allocate 80% of the wireless charging ratio to the phone and 20% to the smartwatch (assuming that 20% is exactly the smartwatch's rated charging power). If the user wants to modify the allocated wireless charging ratio, the dock can adjust the charging ratio according to the user's settings (determining the charging set), such as allocating 90% of the wireless charging ratio to the phone and 10% to the smartwatch.

[0219] For example, a mobile phone and an earphone case (wireless earphones) are placed on a wireless charging dock, which simultaneously provides wireless power to both. The charging dock identifies the models of the devices being charged (i.e., the mobile phone and the earphone case). Based on preset wireless charging rules, the charging dock can allocate 70% of the wireless charging power to the mobile phone and 30% to the earphone case (assuming 30% is the rated charging power of the earphone case). If the user wants to modify the allocated wireless charging power, the charging dock can determine the charging set based on the user's settings (e.g., determining to allocate 90% of the wireless charging power to the mobile phone (first determined charging value) and 10% to the earphone case (second determined charging value). A finalized charging set is generated based on the first and second determined charging values.

[0220] For example, a mobile phone, smartwatch, and earphone case are all placed on a wireless charging dock, which simultaneously provides wireless power to all three devices. The wireless charging dock determines the device signal of the device being charged based on device information, meaning it determines to provide wireless power to the phone, smartwatch, and earphone case. Based on preset charging rules, the dock can allocate 50% wireless charging to the phone, 20% to the smartwatch, and 30% to the earphone case. If the user wants to modify the allocated wireless charging ratios, the wireless charging dock can adjust them according to the user's settings (determining the charging set), such as allocating 80% wireless charging to the phone, 10% to the smartwatch, and 10% to the earphone case.

[0221] Step 507: The phone sends information to the wireless charging dock indicating that it is the device to be charged first.

[0222] In the first implementation described above, in response to the user's operation, the device to be charged first is determined to be the mobile phone, and the mobile phone sends information to the wireless charging dock that the mobile phone is the device to be charged first.

[0223] Suppose that, in response to the user's action, both the mobile phone and the smart bracelet are determined to be devices to be charged. Specifically, after the user selects the device identifier for the mobile phone, the mobile phone receives the user's selection of the smart bracelet's device identifier, and the mobile phone also receives the user's selection of the completion control. Thus, the mobile phone and the smart bracelet are determined to be the priority charging devices, and the mobile phone sends priority charging device information, including information about both the mobile phone and the smart bracelet, to the wireless charging dock.

[0224] Understandably, users can choose at least one device as the priority device to be charged.

[0225] For example, the mobile phone determines the device to be charged first, and the charging power value of at least one of the multiple charging devices, and sends the information of the device to be charged first to the wireless charging dock. The information of the device to be charged first includes the identifier of the device to be charged first and the charging power value of at least one charging device.

[0226] For example, if the phone determines that it is the device to be charged first and receives the setting information that the phone's configured power is 70%, then it sends the phone's device identifier and the phone's configured power to the wireless charging dock.

[0227] Step 508: The wireless charging dock transmits wireless power at a first charging power to the mobile phone, wireless power at a second charging power to the smart bracelet, and wireless power at a third charging power to the tablet. The value of the first charging power is greater than the sum of the second and third charging powers.

[0228] For example, the wireless charging dock receives information about the device to be charged first, and determines the device type of the device to be charged first based on this information. Based on the device type of the device to be charged first, and the device types of the other devices being charged, the wireless charging device allocates charging power to each device. The wireless charging dock can allocate charging power to the device to be charged first according to a preset power allocation algorithm.

[0229] For example, the wireless charging dock determines the phone as the device to be charged first based on the information (priority) sent by the phone. This priority information indicates that a 70% wireless charging rate should be allocated to the phone, a 5% wireless charging rate to the smart bracelet, and a 25% wireless charging rate to the tablet. In response to receiving this information, the wireless charging dock allocates a 70% wireless charging rate (14W) to the phone, a 5% wireless charging rate (1W) to the smart bracelet, and a 25% wireless charging rate (5W) to the tablet.

[0230] For example, the wireless charging dock receives information about the device being charged first (priority). Based on this information, it can determine that the mobile phone is the priority device, and this information indicates that the mobile phone should be allocated a 70% wireless charging rate. Since this information does not include the allocated power for other devices being charged (excluding the mobile phone), the wireless charging dock can allocate wireless charging rates to other devices according to preset charging rules. The wireless charging dock allocates a 70% wireless charging rate (i.e., 14W) to the mobile phone, a 10% wireless charging rate (i.e., 2W) to the smart bracelet, and a 20% wireless charging rate (i.e., 4W) to the tablet.

[0231] It should be noted that when the wireless charging dock provides wireless charging for multiple devices, if the user wants to adjust the charging priority order of the devices, they can interact with the wireless charging dock through their mobile phone to change the charging priority order. Alternatively, if the user wants to change the charging power of the devices, they can interact with the wireless charging dock through their mobile phone to change the configured charging power.

[0232] In some implementations, when a mobile phone receives an instruction to adjust the charging power, it sends a message to the wireless charging dock indicating a change in the configured charging power. The wireless charging dock, upon receiving this message, sends a notification to the mobile phone and displays it. The mobile phone, upon receiving the configuration change notification from the wireless charging dock, displays the changed configuration information.

[0233] like Figure 7 The configuration interface (a) includes the current charging power of the device being charged, and displays a prompt asking "Change charging power configuration?", as well as "Yes" and "No" option controls. In response to the phone receiving a click on the "Yes" option control from the user, the phone displays the following... Figure 7 The power distribution interface is shown in (b). Figure 7 As shown in (b), the power allocation interface includes a power configuration item 61 for the mobile phone, a power configuration item 62 for the smart bracelet, and a power configuration item 63 for the tablet. It also displays the current wireless charging percentage of the device being charged, such as 45% for the mobile phone, 10% for the smart bracelet, and 45% for the tablet.

[0234] Understandably, the phone can receive the percentage of wireless charging rate input by the user. For example... Figure 7In the power allocation interface shown in (c), the phone receives the wireless charging percentage 70 input by the user in the phone's power configuration item 61. In this case, the percentage figures in the smart bracelet's power configuration item 62 and the tablet's power configuration item 63 are also adaptively adjusted. The phone may further receive the user-inputted wireless charging percentage of the smart bracelet, and / or the user-inputted wireless charging percentage of the tablet.

[0235] It is worth mentioning that the mobile phone receives user feedback such as... Figure 7 In the power allocation interface shown in (c), clicking control 65 activates the phone to send the wireless charging ratio to the wireless charging dock. The wireless charging dock then provides wireless charging power to the device being charged according to the wireless charging ratio.

[0236] During the process of the wireless charging dock providing wireless charging power to the device being charged, if the user wants to change the priority of the device being charged, or if the user wants to adjust the wireless charging ratio of the device being charged, the user can interact with their mobile phone to display the following: Figure 7 The interface shown in (a) is shown in the middle.

[0237] Example 2

[0238] A mobile phone, smart bracelet, and tablet can be placed simultaneously on a wireless charging dock, allowing the dock to provide wireless power to all three devices at once. The mobile phone must have a wireless charging app installed; running the app allows users to configure the charging settings on the dock.

[0239] Please refer to Figure 8 This is a flowchart of a charging method provided in an embodiment of this application. Figure 8 As shown, the method includes steps 801-805.

[0240] Step 801: The wireless charging dock transmits the first power to the mobile phone, the second power to the smart bracelet, and the third power to the tablet.

[0241] In this mode, the wireless charging base is in the transmission power stage, and mobile phones, smart bracelets, and tablets receive the charging power transmitted by the wireless charging base.

[0242] Understandably, the wireless charging dock has already allocated charging power (recommended value set) to mobile phones, smart bracelets and tablets according to the preset power allocation principle, and provides wireless power to each device according to the charging power.

[0243] For example, wireless charging docks are recommended to assign a first recommended value to mobile phones, a second recommended value to smart bracelets, and a third recommended value to tablets.

[0244] Step 802: The wireless charging dock establishes a communication connection with the mobile phone.

[0245] Once a wireless charging app is installed on your phone and a wireless charging dock is established, the dock can receive information sent by the phone.

[0246] In some implementations, mobile phones, smart bracelets, and tablets are all placed on a wireless charging dock, which provides wireless power to the devices. For example, the phone may have a wireless charging app installed, and the phone may display something like... Figure 10A The interface shown in (a) is as follows. Among them, as shown in... Figure 10A The diagram in (a) shows a mobile phone being wirelessly charged (92). When a user sees the interface shown in (92) on the mobile phone, they can see that the wireless charging dock is charging the mobile phone.

[0247] In this scenario, if the phone receives a click from the user on the wireless charging application 901, the phone will run the wireless charging application and display something like this. Figure 10A The interface shown in (b) is shown in the middle.

[0248] In this scenario, if the wireless charging app on the phone has a preset charging scenario (e.g., the phone's first charging scenario includes the phone, smart bracelet, and tablet), the phone runs the wireless charging app, interacts with the charging dock, and the charging dock provides wireless power to multiple devices according to the phone's preset first charging scenario. During this process, the user is unaware of the charging activity (i.e., the phone does not need to interact with the user), and the wireless charging dock provides wireless power to multiple devices.

[0249] Understandably, the way wireless charging applications on mobile phones preset the first charging scenario can be as follows: Figure 9 The first charging scenario is created as shown.

[0250] If the wireless charging app on your phone does not have a preset charging scenario, your phone will display something like this: Figure 10A The interface shown in (b) is as follows. Among them, as... Figure 10A As shown in (b), the interface includes the currently charged devices, namely, a phone (marked 93), a smart bracelet (marked 94), and a tablet (marked 95); and a control 96 for creating a charging scene. Taking the phone (marked 93) as an example, the wireless charging dock provides wireless power to the phone, smart bracelet, and tablet. The wireless charging dock can provide wireless power to multiple charged devices according to the preset principle of distributing charging power to the charged devices. The phone (marked 93) corresponds to the phone's device identifier, device name (e.g., phone), and the device's current wireless charging percentage (e.g., 70%).

[0251] Understandably, if a user wants to change the wireless charging rate of the device being charged, the phone can receive the wireless charging rate input by the user.

[0252] For example, if a user wants to set the current charging scene as a new charging scene, they can click "Create as My Charging Scene 96". Upon receiving this click, the phone can display something like: Figure 9 The interface shown in (c) is used to enable the phone to create a wireless charging scene.

[0253] It should be noted that if the phone has a preset charging scenario, the phone will display something like this. Figure 10B In the interface shown in (a), the mobile phone receives the user's click operation on the wireless charging application 901, and the mobile phone displays as follows. Figure 10B The interface shown in (b) is as follows. Among them, as... Figure 10B The interface shown in (b) includes the current charging scenario being the preset first charging scenario, and includes the identifier, name, and charging power percentage of each device being charged. If the user wants to change the charging power settings of the current charging scenario, such as the charging power percentage of the device being charged, the phone can receive the user's click operation on the settings. The phone can adjust the settings in the first charging scenario based on the received user operation information.

[0254] Step 803: The mobile phone runs the wireless charging application, which includes the charging method of the first charging scenario. The first charging scenario indicates that the wireless charging base can simultaneously provide wireless power to the mobile phone, smart bracelet and tablet.

[0255] Regardless of whether the phone is wirelessly charging, it can run the wireless charging application and receive the wireless charging scenarios set by the user.

[0256] The phone displays as follows Figure 9 The main interface shown in (a) includes a wireless charging application 901. In response to a user's click on the wireless charging application 901, the phone displays the following: Figure 9 The wireless charging application interface is shown in (b). Figure 9 The interface shown in (b) includes all charging scenarios in the wireless charging application, as well as controls for creating charging scenarios. In response to a user's click to create a charging scenario, the phone displays the following... Figure 9 The identifier of the device being charged is shown in (c). Figure 9 The interface shown in (c) includes a device addition control. When the phone receives a user's click to add the device control, it displays various device icons that can be wirelessly charged. For example... Figure 9As shown in (c), the currently created scene includes device identifiers for a mobile phone, a smart bracelet, and a tablet. In response to the user's click on the completion control, the mobile phone displays the following... Figure 9 The interface shown in (d). Among them, as... Figure 9 The interface shown in (d) includes a configuration charging power item for each device being charged, and each configuration charging power item can receive input data. This completes the creation of a charging scenario.

[0257] For example, in the first charging scenario, the wireless charging dock charges a mobile phone, a smart bracelet, and a tablet. The charging power of the mobile phone is set to 70%, the charging power of the smart bracelet to 10% (the rated charging power of the smart bracelet is 20%), and the charging power of the tablet to 20%.

[0258] Step 804: The mobile phone sends the charging method of the first charging scenario to the wireless charging dock via wireless communication.

[0259] In the first charging scenario, the charging power of mobile phones is the fourth power, the charging power of smart bracelets is the fifth power, and the charging power of tablets is the sixth power.

[0260] It should be noted that the charging method in the first charging scenario is the same as the current charging method of the wireless charging dock. That is, the power allocated by the wireless charging dock to each device is consistent with the settings of the first charging scenario, so the wireless charging dock does not need to adjust the charging power.

[0261] Step 805: The wireless charging dock determines that the current charging scenario matches the first charging scenario. The wireless charging dock then transmits a fourth power to the mobile phone, a fifth power to the smart bracelet, and a sixth power to the tablet.

[0262] The wireless charging dock provides wireless power to mobile phones, smart bracelets, and tablets according to the settings parameters in the first charging scenario.

[0263] The above explanation uses the example of a wireless charging dock as the wireless charging device and the dock interacting with the user via a mobile phone. When the wireless charging dock is another wireless charging device and the mobile phone is another device, the same method can be used to provide wireless power. This will not be elaborated upon here.

[0264] It is understood that, in order to achieve the aforementioned functions, the wireless charging device includes corresponding hardware structures and / or software modules for performing each function.
