[0046] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0047] The technical solution disclosed in the present invention is applied to the wireless charging technology scenario. The wireless charging system in this scenario includes a first electronic device and a second electronic device with a bidirectional wireless charging function. Wireless charging technology refers to a technology that realizes contactless power transmission through an air medium by electromagnetic induction, electromagnetic resonance, radio frequency, microwave, laser, etc. instead of wires. Compared with traditional wired charging, wireless charging technology is more convenient because it does not require wiring.

[0048] There are three main methods of wireless charging technology: electromagnetic induction, magnetic field resonance, and radio wave. There are three main wireless charging standards: PMA (Power Matters Alliance) standard, Qi standard, and A4WP (Alliance for Wireless Power) standard. At present, the mainstream wireless charging technology is electromagnetic induction technology, and the mainstream wireless charging standard is Qi standard. Among them, Qi is an interconnection standard for short-distance (40mm, 1.6 inches) low-power wireless inductive power transmission established by the Wireless Power Consortium (WPC). It uses mainstream electromagnetic induction technology to provide convenient and universal wireless charging for mobile devices.

[0049] Wireless charging devices are used to charge wireless charging receiving devices with wireless charging functions. For example, wireless charging devices can be wireless charging mobile power supplies, wireless charging pads, wireless chargers, etc., or mobile terminal devices with two-way wireless charging functions that can use batteries for wireless charging, such as mobile phones, laptops, tablets, PDAs, wireless headphones, and other devices.

[0050] Bidirectional wireless charging is a technology that allows two devices to transfer power to each other without the need for a physical connection or plug. This means that both the first electronic device and the second electronic device can act as a wireless charging transmitter and a wireless charging receiver to achieve wireless charging between each other.

[0051] Figure 1 is a schematic diagram of a wireless charging scenario according to an exemplary embodiment. Figure 1 As shown, the wireless charging system in this scenario includes a first electronic device and a second electronic device with a bidirectional wireless charging function. The first electronic device and the second electronic device can be wirelessly charged through their own first coil and second coil and wirelessly reversely charge other devices.

[0052] In the related art, if charging control is not performed, some devices may have very high power while other devices may have very low power. In this case, the charging efficiency of the low-power device to the high-power device is very low, which will cause resource waste, and the low-power device may not be used normally due to insufficient power.

[0053] In view of this, a wireless charging method is proposed in an embodiment of the present disclosure. In the wireless charging method provided by the present disclosure, when a first electronic device is in a wireless charging power balancing mode and detects a second electronic device to be charged, the power of the second electronic device is obtained, and the power of the second electronic device is compared with the power of the second electronic device to avoid the situation where a low-power device becomes a high-power device, and the power balancing of the wireless charging devices is achieved.

[0054] Figure 2 is a flow chart of a wireless charging method according to an exemplary embodiment. Figure 1 As shown, the method is applied to a wireless charging transmitting end device, namely, a first electronic device, in an initial state where a wireless charging power balancing mode is turned on, and includes steps S11 to S12.

[0055] In step S11, in response to determining that the first electronic device is in a wireless charging power balancing mode and detecting a second electronic device to be charged, the power of the second electronic device is obtained. The wireless charging power balancing mode is used to achieve a power balancing state of the wireless charging devices.

[0056] The power balancing state includes a state in which the difference between the power of the first electronic device and the power of the second electronic device is less than a threshold.

[0057] In step S12, in response to determining that the power level of the second electronic device is greater than the power level of the first electronic device, charging of the second electronic device is stopped.

[0058] The first electronic device is a wireless charging transmitting device in an initial state in which a wireless charging power balancing mode is turned on. When charging starts, the first electronic device detects a wireless charging receiving device, i.e., a second electronic device, in an initial state in which a wireless charging power balancing mode is turned on through a wireless presence detection function of the wireless charging device.

[0059] The wireless presence detection function refers to a technology used to detect the relative position and distance between devices to ensure the correct alignment and appropriate distance between devices during the wireless charging process. This ensures that the charging wireless charging transmitter and the wireless charging receiver can perform normal wireless energy transmission before starting wireless charging, thereby improving charging efficiency and safety. For example, the wireless presence detection function may include Ping signal detection and quality factor Q value detection. Ping signal detection is a method of using wireless signals, usually by sending a short pulse or signal packet to detect the position between devices. Q value detection is a method using the principle of electromagnetic induction. In this method, the transmitter device monitors the characteristics of the RF field and measures the Q value to understand the relative position and distance between devices.

[0060] When the first electronic device is in the wireless charging power balancing mode, it will periodically obtain the power of the second electronic device and compare it with the current power. After determining that the power of the second electronic device is greater than the power of the first electronic device, the first electronic device will stop charging the second electronic device, thereby avoiding the problem of increased energy consumption and waste of resources caused by low-power devices charging high-power devices.

[0061] In the embodiment of the present disclosure, when the first electronic device is in the wireless charging power balancing mode, the power of the second electronic device is obtained and compared, and when the power of the second electronic device is greater than the power of the first electronic device, charging of the second electronic device is stopped. The method in the embodiment of the present disclosure avoids unnecessary power transmission, reduces power waste between devices, and improves the effective use of energy.

[0062] In one embodiment, there may be only one electronic device that supports or turns on the wireless charging power balancing mode in the embodiment of the present disclosure. The electronic device that supports or turns on the wireless charging power balancing mode in the embodiment of the present disclosure can be used as the first electronic device to execute the wireless charging method in the embodiment of the present disclosure, and the other device can be used as the second electronic device to execute the wireless charging method in the embodiment of the present disclosure.

[0063] In another embodiment, for electronic devices that are all in the wireless charging power balancing mode in the embodiment of the present disclosure, the electronic device sends a receiving end detection through a ping signal or a quality factor Q value, and the electronic device that first detects the receiving end device is used as the first electronic device to execute the wireless charging method in the embodiment of the present disclosure, and the other device, the second electronic device, executes the wireless charging method in the embodiment of the present disclosure.

[0064] Figure 3 is a flow chart showing a method for switching a charging state according to an exemplary embodiment. Figure 3 As shown, the method is applied to a first electronic device, and includes steps S21 to S22.

[0065] In step S21, a communication packet is sent to the second electronic device, where the communication packet includes the state information and control instructions of the first electronic device.

[0066] The communication packet is a data packet containing status information and control information for transmitting power in the wireless charging system. The control instruction can be used to instruct the second electronic device to switch from receiving charging energy to transmitting charging energy. The status information of the first electronic device can be used by the second electronic device to adjust charging information such as charging power according to the status information of the first electronic device.

[0067] In step S22, the state of stopping charging is switched to the state of receiving charging energy.

[0068] The first electronic device stops charging the second electronic device and sends a communication packet to the second electronic device. After completing the sending of the communication packet, the first electronic device enters the initial charging waiting state. During the charging waiting process, the first electronic device receives a detection signal from the second electronic device and will serve as a new wireless charging receiving end device, switching from the charging stop state to the charging energy receiving state.

[0069] In the embodiment of the present disclosure, when the first electronic device detects that the power of the second electronic device is greater than the power of the first electronic device, the first electronic device stops charging the second electronic device and sends a communication packet including the status information and control instructions of the first electronic device to the second electronic device. After completing the sending of the communication packet, the first electronic device switches from the charging stop state to the charging energy receiving state. By sending a communication packet including the status information and control instructions of the first electronic device to the second electronic device, timely communication between devices is achieved. This helps to coordinate charging and power distribution between devices to meet specific needs. Switching the first electronic device from the charging state to the charging energy receiving state enables the device to effectively adjust its charging state to respond to the need for power balancing. This helps to improve the efficiency of charging and energy utilization.

[0070] In one embodiment, in response to determining that the power level of the second electronic device is less than or equal to the power level of the first electronic device, the second electronic device continues to be charged and the power level of the second electronic device is periodically obtained until it is determined that the difference between the power levels of the first electronic device and the second electronic device is less than a threshold.

[0071] In the embodiment of the present disclosure, when the power of the second electronic device is less than or equal to the power of the first electronic device, the first electronic device will continue to charge the second electronic device. During the charging process, the power of the second electronic device is periodically obtained and compared with that of the first electronic device. If the difference between the power of the first electronic device and the power of the second electronic device is less than the set threshold, it is determined that the power balance of the electronic devices is achieved, the charging mode is exited, and the wireless charging is stopped.

[0072] In one embodiment, the first electronic device obtains the power of the second electronic device by receiving a power packet sent by the second electronic device. The power packet is a data packet containing power information. The power packet can be transmitted by wireless in-band communication or out-of-band communication.

[0073] Wireless in-band communication may be communication in which the carrier and the charging beam have the same frequency band, or the charging beam is directly used as a carrier for signal transmission. Wireless out-of-band communication may be communication in which a carrier different from the charging beam frequency band is used for signal transmission. For example, wireless out-of-band communication may be Bluetooth, near field communication, and WiFi.

[0074] In one embodiment, in response to a first electronic device being connected to a wired charging power source, if the power level of a second electronic device is greater than the power level of the first electronic device, the first electronic device is charged via the wired charging power source until the power level of the first electronic device is greater than the power level of the second electronic device, and the second electronic device is charged.

[0075] Figure 4 is a schematic diagram showing a scenario in which a first electronic device is connected to a wired charging power source according to an exemplary embodiment. Figure 4 As shown, the first electronic device is connected to an external wired charging power source through a wired interface, and simultaneously wirelessly charges the second electronic device through the first coil and the second coil of the second electronic device.

[0076] If the power level of the first electronic device is greater than that of the second electronic device, the first electronic device automatically wirelessly charges the second electronic device; if the power level of the first electronic device is less than that of the second electronic device, the first electronic device is charged through a wired charging power supply until the power level of the first electronic device is greater than that of the second electronic device, and the second electronic device is charged.

[0077] For example, the first electronic device is a mobile charging power supply with a wireless charging function, and the second electronic device is a smart phone with a wireless charging function. In the wireless charging power balancing mode, the mobile charging power supply can charge the smart phone, and when its own power is less than the power of the second electronic device, it can be charged through a wired charging power supply, and finally the first electronic device and the second electronic device can be charged to a full power state in a balanced manner.

[0078] In the disclosed embodiment, a first electronic device connected to a wired charging power source wirelessly charges a second electronic device, and switches to a wired charging power source when the first electronic device is low on power, thereby achieving seamless charging switching. This ensures balanced charging and full charging without manual intervention by the user. By maximizing the use of available power and avoiding unnecessary power waste, power distribution is optimized, which helps to improve the efficient use of energy.

[0079] Figure 5 is a flow chart of a method for controlling a user interface in a wireless charging power balancing mode according to an exemplary embodiment. Figure 5 As shown, the method includes steps S61 to S62.

[0080] In step S61, if the wireless charging power balancing mode switch in the status bar of the first electronic device is in the on state, it is determined that the first electronic device is in the wireless charging power balancing mode.

[0081] In step S62, if the wireless charging power balancing mode switch in the wireless charging application setting interface of the first electronic device is in an on state, it is determined that the first electronic device is in the wireless charging power balancing mode.

[0082] In the disclosed embodiment, the user may control the wireless charging power balancing mode through the status bar and notification center of the device or the application setting interface.

[0083] For example, Fig. 6A FIG. 1 is a schematic diagram showing a user interface of a wireless charging power balancing mode according to an exemplary embodiment. Fig. 6A As shown, the user opens the status bar or notification center of the device, finds the switch of the wireless charging power balancing mode, which is usually displayed as a switch button or icon, and clicks the switch button to turn the wireless charging power balancing mode on or off. If the user turns on the switch, it means that the first electronic device is in the wireless charging power balancing mode.

[0084] For example, Figure 6B FIG. 1 is a schematic diagram showing another wireless charging power balancing mode user interface according to an exemplary embodiment. Figure 6B As shown, the user opens the wireless charging application or setting interface on the device. In the application or setting interface, find the option of wireless charging power balancing mode, which is usually presented in the form of a switch button. The user clicks the switch button to enable or disable the wireless charging power balancing mode. If the user turns on the switch in the application setting interface, it means that the first electronic device is in the wireless charging power balancing mode.

[0085] The application interface may also provide information about the mode status, such as the power balance status of the first electronic device and the second electronic device and other related information.

[0086] In some embodiments, the user can also interact with the wireless charging power balancing mode in multiple modes through the user interface (UI). For example, the user sets the specific conditions of the power balancing state in which charging is finally stopped, and when the power balancing state is reached, a prompt message is sent through the UI, a pop-up window is called up, and the user is asked whether to continue charging.

[0087] In the disclosed embodiment, the user can interact and control the wireless charging power balancing mode through the user interface (UI), which enables the user to monitor the status of the device in real time and flexibly adjust the mode according to the power status of the devices, usage scenarios or other factors to meet different charging needs.

[0088] Figure 7 is a flow chart of another wireless charging method according to an exemplary embodiment. Figure 7 As shown, the method is applied to a wireless charging receiving device, namely, a second electronic device, in an initial state where a wireless charging power balancing mode is turned on, and includes steps S71 to S72.

[0089] In step S71 , in response to determining that the second electronic device is in the wireless charging power balancing mode, energy transmitted by the first electronic device is received.

[0090] In step S72, the power level of the second electronic device is sent to the first electronic device.

[0091] The power balancing state includes a state in which the difference between the power of the first electronic device and the power of the second electronic device is less than a threshold.

[0092] In the disclosed embodiment, the second electronic device acts as a wireless charging receiving end to receive energy transmitted by the first electronic device. When the second electronic device is in the wireless charging power balancing mode, it periodically sends the power of the second electronic device to the first electronic device to avoid the problem of increased energy consumption and waste of resources caused by a low-power device charging a high-power device.

[0093] In one embodiment, the second electronic device may also be an electronic device that does not support or does not enable the wireless charging power balancing mode in the embodiment of the present disclosure, and executes the wireless charging method in the embodiment of the present disclosure by receiving a control signal sent by the first electronic device that supports or enables the wireless charging power balancing mode in the embodiment of the present disclosure.

[0094] In one embodiment, when the first electronic device detects that the power of the second electronic device is greater than that of the first electronic device, it will send a communication packet to the second electronic device, and the second electronic device will receive the communication packet sent by the first electronic device. The communication packet includes the state information of the first electronic device and a control instruction, and the control instruction is used to instruct the second electronic device to switch from receiving charging energy state to transmitting charging energy state.

[0095] Figure 8 is a flow chart showing another method for switching charging states according to an exemplary embodiment. Figure 8 As shown, the method is applied to a wireless charging receiving device, namely, a second electronic device, in an initial state where a wireless charging power balancing mode is turned on, and includes steps S91 to S93.

[0096] In step S91, the second electronic device stops receiving energy and enters a charging preparation phase.

[0097] In step S92, a detection signal is sent to the first electronic device in the charging preparation stage.

[0098] In step S93, when the first electronic device is detected, the charging phase is entered to charge the first electronic device and periodically obtain the power of the first electronic device until it is determined that the difference between the power of the second electronic device and the power of the first electronic device is less than a threshold.

[0099] In the disclosed embodiment, after receiving the communication packet sent by the first electronic device, the second electronic device stops receiving energy and enters the charging preparation stage, ensuring the orderly charging. By sending a detection signal to the first electronic device, the presence and location of the device are detected, and the subsequent charging operation is ready. After entering the charging stage, the second electronic device charges the first electronic device and periodically obtains its power information. This helps to intelligently manage power distribution to meet the needs of a balanced power state.

[0100] In one embodiment, the second electronic device sends the power of the second electronic device to the first electronic device by sending a power packet. The power packet is a data packet containing power information. The power packet can be transmitted by wireless in-band communication or out-of-band communication.

[0101] Wireless in-band communication may be communication in which the carrier and the charging beam have the same frequency band, or the charging beam is directly used as a carrier for signal transmission. Wireless out-of-band communication may be communication in which a carrier different from the charging beam frequency band is used for signal transmission. For example, wireless out-of-band communication may be Bluetooth, near field communication, and WiFi.

[0102] In one embodiment, determining that the second electronic device is in the wireless charging power balancing mode includes: if the wireless charging power balancing mode switch in the status bar of the second electronic device is in an on state, determining that the second electronic device is in the wireless charging power balancing mode. If the wireless charging power balancing mode switch in the wireless charging application setting interface of the second electronic device is in an on state, determining that the second electronic device is in the wireless charging power balancing mode.

[0103] In some embodiments, the user can also interact with the wireless charging power balancing mode in multiple modes through the user interface (UI). For example, the user sets the specific conditions of the power balancing state in which charging is finally stopped, and when the power balancing state is reached, a prompt message is sent through the UI, a pop-up window is called up, and the user is asked whether to continue charging.

[0104] In the disclosed embodiment, the user can interact and control the wireless charging power balancing mode through the user interface (UI), which enables the user to monitor the status of the device in real time and flexibly adjust the mode according to the power status of the devices, usage scenarios or other factors to meet different charging needs.

[0105] In one embodiment, the wireless charging method involved above can also be applied to the application scenario of integrating and judging the power status of multiple electronic devices with a two-way wireless charging function to achieve complementary power balance of multiple electronic devices. For example, an electronic device as a wireless charging transmitting device in an initial state, i.e., a first electronic device, charges multiple wireless charging receiving devices in an initial state, i.e., a second electronic device, and executes the wireless charging method in the embodiment of the present disclosure. During the charging process, the power information of multiple electronic devices is comprehensively judged, and the wireless charging device with the highest power is always used as the first electronic device to charge other electronic devices, and finally a state of complementary power balance of multiple devices is achieved.

[0106] The wireless charging method mentioned above is described below in conjunction with an example in the embodiments of the present disclosure. A wireless charging transmitting device (TX) is used as a first electronic device, and a wireless charging receiving device (RX) is used as a second electronic device.

[0107] Wireless charging smart devices can wirelessly charge other smart devices. During the wireless charging process, the energy of the transmitter needs to be consumed. If the power of the receiving device is higher or higher than that of the transmitting device, the energy efficiency of the device is undoubtedly not optimal, which is easy to cause useless consumption of energy. For example, a first electronic device with a two-way wireless charging function wirelessly charges a smartphone with 80% power for a second electronic device with a two-way wireless charging function and a smartphone with 20% power. In the absence of charging control, the first electronic device will always keep charging the second electronic device, and when the power of the second electronic device is greater than that of the first electronic device, it will still be charged, causing great energy loss and waste.

[0108] In view of this, in an embodiment of the present disclosure, a wireless charging method is proposed.

[0109] Fig. 9 FIG. 1 is a flow chart of a wireless charging method according to an exemplary embodiment. Fig. 9 As shown, in response to the wireless charging power balancing mode being started, the wireless charging transmitting device detects the receiving device through the wireless charging presence detection function. After detecting that the wireless charging receiving device is close to or near the wireless charging transmitting device, it starts charging the wireless charging receiving device.

[0110] The wireless charging receiving device periodically sends power information to the wireless charging sending device by transmitting power packets.

[0111] The wireless charging transmitting device compares the current power level with the power level of the wireless charging receiving device. If the current power level is greater than the power level of the wireless charging receiving device, it continues to transmit energy to the wireless charging receiving device.

[0112] If it is detected that the current power is less than the power of the wireless charging receiving device, the wireless charging receiving device will stop charging, and the wireless charging sending device and the wireless charging receiving device will return to the initial state. At this time, the low-power device will stop the detection mode, and the high-power device will start the detection mode, so that the high-power device can be used as a wireless charging sending device, and then the wireless charging function can be turned on.

[0113] In the disclosed embodiment, the device has a wireless charging in-place detection function. When two devices are close to each other, the wireless charging preparation mode of the device will be triggered. In this preparation mode, the wireless charging device transmits power information through wireless in-band communication or out-of-band communication, determines and decides that the high-power smart device will wirelessly charge the low-power device until the power is balanced. This wireless charging method improves the efficiency of wireless charging and avoids ineffective waste of resources.

[0114] Based on the same concept, an embodiment of the present disclosure also provides a wireless charging device.

[0115] It is understandable that in order to realize the above functions, the wireless charging device provided by the embodiment of the present disclosure includes hardware structures and / or software modules corresponding to the execution of each function. In combination with the units and algorithm steps of each example disclosed in the embodiment of the present disclosure, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the technical solution of the embodiment of the present disclosure.
