[0033] The above is a brief description of the wireless power supply device and the wireless power receiving device. The following will describe the display method of the wireless power supply device in detail. Please refer to Figure 6 The display method can include the following steps: Step 100: wirelessly supply power to the wireless power receiving device.

[0034] Please refer to Figure 4 In some embodiments, the first processor 30 of the wireless power supply device controls the wireless power supply component 10 to convert the first electric signal for power supply into a first electromagnetic signal, and transmits the first electromagnetic signal to the wireless power receiving device to wirelessly supply power to the wireless power receiving device. For example, the wireless power supply device converts the direct-current first electric signal into an alternating-current first electric signal based on the current direction adjustment circuit 12, and the alternating-current first electric signal generates a corresponding first electromagnetic signal after passing through the power supply coil 14.

[0035] The wireless charging component 40 of the wireless power receiving device receives the first electromagnetic signal transmitted by the wireless power supply device, converts the first electromagnetic signal into a second electric signal, and enables the electric energy conversion component 50 to obtain the charging electric energy based on the second electric signal.

[0036] In some embodiments, when wirelessly supplying power to the wireless power receiving device, the first processor 30 is further configured to obtain first state information of the wireless power supply component 10 when wirelessly supplying power to the wireless power receiving device. The first state information at least includes the output power of the wireless power supply component 10 when transmitting the first electromagnetic signal to the wireless power receiving device.

[0037] In some embodiments, the first status information can further include at least one of an under-voltage alarm, an over-voltage alarm, power supply temperature information, and wireless charging protocol information. The wireless power supply device can detect the voltage of the wireless power supply assembly 10 based on the voltage detection circuit, and generate a corresponding under-voltage alarm when the voltage is less than a low voltage threshold, and generate a corresponding over-voltage alarm when the voltage is higher than an over-voltage threshold. The wireless power supply device can obtain the power supply temperature information based on a temperature sensor, for example, the temperature sensor can detect the temperature of the wireless power supply assembly 10. The wireless charging protocol information can be obtained based on a handshake protocol between the wireless power supply device and the wireless power receiving device.

[0038] In some embodiments, the first processor 30 can adjust the power of the first electrical signal, thereby adjusting the output power for wirelessly supplying power to the wireless power receiving device.

[0039] Step 200: Obtain the status information of the wireless power receiving device.

[0040] In some embodiments, the first processor 30 receives the second electromagnetic signal sent by the wireless power receiving device based on the wireless power supply assembly 10, and converts the second electromagnetic signal into a third electrical signal, demodulates the third electrical signal, and obtains the second status information of the wireless power receiving device.

[0041] The wireless power receiving device obtains the second status information of the power conversion assembly 50 when obtaining the charging power, modulates the second status information on the fourth electrical signal for communication by the wireless charging assembly 40, converts the modulated fourth electrical signal into a second electromagnetic signal, and sends the second electromagnetic signal to the wireless power supply device.

[0042] In some embodiments, the second status information at least includes the charging power of the wireless power receiving device when obtaining the charging power. For example, the wireless power receiving device can also detect the power of the power conversion assembly 50 based on the power detection circuit to obtain the charging power of the power conversion assembly 50 when obtaining the charging power.

[0043] In some embodiments, the second status information further includes at least one of charging efficiency information, power information, and charging temperature information. The wireless power receiving device can calculate the charging efficiency information based on the target charging power and the actually detected charging power. The wireless power receiving device can detect the power of the energy storage device in the power conversion assembly 50 based on the power detection circuit to obtain the corresponding power information. The wireless power receiving device can obtain the charging temperature information based on a temperature sensor, for example, the temperature sensor can detect the temperature of the power conversion assembly 50.

[0044] In some embodiments, the wireless power receiving device can modulate its second state information on the fourth electrical signal for communication based on a FSK modulation manner or an ASK modulation manner, and the first processor 30 can demodulate the third electrical signal based on a corresponding demodulation manner.

[0045] In some embodiments, the wireless power supplying device can send information to the wireless power receiving device when wirelessly supplying power to the wireless power receiving device, which will be described below.

[0046] In some embodiments, the first processor 30 modulates preset communication protocol information on the first electrical signal. The communication protocol information can represent the state information of the wireless power receiving device that needs to be acquired. Then the wireless power supplying assembly 10 converts the modulated first electrical signal into a third electromagnetic signal and sends the third electromagnetic signal to the wireless power receiving device. On the one hand, the wireless power receiving device receives the third electromagnetic signal based on the wireless charging assembly 40, converts the third electromagnetic signal into a fifth electrical signal, and acquires charging power based on the fifth electrical signal through the electrical energy conversion assembly 50. On the other hand, the wireless power receiving device demodulates the fifth electrical signal to obtain the communication protocol information, and modulates second state information corresponding to the communication protocol information on a fourth electrical signal for communication in response to the communication protocol information.

[0047] In some embodiments, the wireless power supplying device can modulate preset communication protocol information on the first electrical signal based on a FSK modulation manner or an ASK modulation manner, and the wireless power receiving device can demodulate the fifth electrical signal based on a corresponding demodulation manner.

[0048] In the above embodiments, the wireless power supplying device can also wirelessly supply power to the wireless power receiving device based on the first electrical signal, or wirelessly supply power to the wireless power receiving device and send information based on the first electrical signal modulated with information.

[0049] In some embodiments, the wireless power supplying device can also send information to the wireless power receiving device when not wirelessly supplying power to the wireless power receiving device. For example, before the wireless power supplying device supplies power to the wireless power receiving device, the wireless power supplying device and the wireless power receiving device communicate based on a handshake protocol to acquire corresponding wireless charging protocol information based on the handshake protocol, wherein the wireless charging protocol information includes wireless charging standards (such as QI protocol), target charging power, and other information.

[0050] In some embodiments, the wireless power supply device can further obtain the device type of the wireless power receiving device based on the handshake protocol, and after obtaining the device type of the wireless power receiving device, determine the communication protocol information corresponding to the device type, and modulate the corresponding communication protocol information on the first electrical signal. Different device types correspond to different communication protocol information, which can represent different state information. For example, for different types of devices such as mobile phones, test racks, and aging racks, the wireless power supply device can obtain the same state information, or different state information based on different communication protocol information.

[0051] In some embodiments, the wireless power supply device and the wireless power receiving device use multiplexing to complete wireless charging and communication using the coil. For example, the wireless power supply device and the wireless power receiving device use the coil to complete wireless charging and communication based on a first time period and a second time period, respectively, and the first time period and the second time period do not overlap.

[0052] The first processor 30 is configured to control the wireless power supply component 10 to convert the first electrical signal for power supply into a first electromagnetic signal in the first time period, and send the first electromagnetic signal to the wireless power receiving device to wirelessly supply power to the wireless power receiving device. The wireless power receiving device controls the wireless charging component 40 to receive the first electromagnetic signal sent by the wireless power supply device in the first time period, converts the first electromagnetic signal into a second electrical signal, and enables the power conversion component 50 to obtain charging power based on the second electrical signal.

[0053] The wireless power receiving device controls the wireless charging component 40 to modulate the second state information on the fourth electrical signal for communication in the second time period, and converts the modulated fourth electrical signal into a second electromagnetic signal, and sends the second electromagnetic signal to the wireless power supply device. The first processor 30 is configured to receive the second electromagnetic signal sent by the wireless power receiving device based on the wireless power supply component 10 in the second time period, and convert the second electromagnetic signal into a third electrical signal.

[0054] Step 300: Display the state information.

[0055] In some embodiments, the display component 20 displays the second state information. At this time, the user can clearly understand the actual charging condition of the wireless power receiving device based on the second state information, thereby facilitating the user to better use the wireless power supply device for wireless charging. For example, when the actual charging power of the wireless power receiving device is significantly lower than the target charging power, the first processor 30 can display a prompt information based on the display component 20 to prompt the user to adjust the charging position of the wireless power receiving device, or to check whether the wireless charging standard is matched.

[0056] In some embodiments, the display component 20 displays the first state information and the second state information. At this time, not only the actual charging condition of the wireless power receiving device is displayed, but also the actual power supply condition of the wireless power supply device is displayed, thereby further facilitating the user to better use the wireless power supply device for wireless charging.

[0057] In the above embodiments, after the wireless power receiving device obtains the actual charging power, the wireless power receiving device sends the current actual charging power to the wireless power supply device based on the multiplexing manner, so that the wireless power supply device can accurately obtain the current actual charging power of the wireless power receiving device and display it, thereby being able to display more accurate charging power to the user in real time.

For example, the first processor itself can control the wireless power supply assembly to supply power to the wireless power receiving device, but based on the control of the third processor 74, the first processor can acquire the second state information of the wireless power receiving device. The control process implemented by the first processor based on the control of the third processor 74 can be configured according to actual needs, which will not be repeated here.

[0069] In the above-mentioned embodiments, based on the connection of the data line with the wireless power supply device, when the wireless power supply device does not have the display function and the function of displaying the second state information, the actual charging power of the wireless power receiving device when acquiring the charging power can also be acquired based on the data line and displayed, so that the user can intuitively understand the actual charging condition of the wireless power receiving device.
