[0083] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0084] Figure 1 is a schematic diagram of the structure of a test device according to an exemplary embodiment Figure 1 ,like Figure 1 As shown, the test device 100 includes:

[0085] The wireless charging transmitter 101 is configured to obtain a first electrical parameter of a first wireless charging receiver of the device under test when the test device 100 provides power to the device under test, and to send the first electrical parameter and a second electrical parameter of the wireless charging transmitter 101 to a terminal device;

[0086] a second wireless charging receiver 102 connected to the wireless charging transmitter 101, configured to obtain a third electrical parameter of the second wireless charging receiver 102 when the test device 100 obtains power from the device under test, and to send the third electrical parameter to the terminal device;

[0087] The first charging coil 103 is connected to the wireless charging transmitter 101 and the second wireless charging receiver 102 respectively, and is used to generate electromagnetic induction with the second charging coil included in the device under test to provide power to the device under test or obtain power from the device under test. Figure 2 The structure of the device under test is shown according to an exemplary embodiment. Figure 2 ,like Figure 2 As shown, the device under test 201 may be a mobile phone.

[0088] Here, both the test device and the device under test are electronic devices with wireless charging capabilities, and the test device is integrated with a test board that includes a wireless charging transmitter, a second wireless charging receiver, and a first charging coil. The device under test can be a terminal device with wireless charging capabilities, such as a mobile terminal. Mobile terminals include mobile phones, laptops, tablets, wearable electronic devices, smart speakers, and the like.

[0089] In the disclosed embodiments, since the test device has a first charging coil and the device under test has a second charging coil, during implementation, the test device can provide power to the device under test, or obtain power from the device under test, through magnetic induction technology. For example, after the test device is powered on, the device under test can be placed on a test bench of the test device. In this way, the first charging coil on the test device and the second charging coil on the device under test can generate electromagnetic induction, thereby causing the device under test to enter a wireless charging state.

[0090] In some embodiments, the wireless charging transmitter includes a NU1020 chip, the second wireless charging receiver includes a NU1619 chip, and the first charging coil includes an MP-A2 wireless charging coil.

[0091] In some embodiments, upon detecting that the test device is powered on, the wireless charging transmitter can be controlled to be in an active state, and the second wireless charging receiver can be controlled to be in an inactive state. In this case, the test device can provide power to the device under test, and while the test device is providing power to the device under test, a first electrical parameter of the first wireless charging receiver of the device under test is obtained, and the first electrical parameter and the second electrical parameter of the wireless charging transmitter are transmitted to the terminal device.

[0092] In some embodiments, the wireless charging transmitter can send the first electrical parameter and the second electrical parameter to the terminal device via serial communication. For example, the first electrical parameter and the second electrical parameter can be transmitted via a serial interface. In other optional embodiments, the first electrical parameter and the second electrical parameter can also be sent to the terminal device in other ways, for example, via a wireless network or ZigBee technology.

[0093] In some embodiments, the terminal device may be an electronic device with data processing capabilities, for example, a mobile terminal or a fixed terminal with a processor. Mobile terminals include mobile phones, laptops, tablet computers, etc. Fixed terminals include personal computers (PCs), etc. In other embodiments, the terminal device may also be a server.

[0094] In the embodiment of the present disclosure, after sending the first electrical parameter and the second electrical parameter to the terminal device, the terminal device may process the first electrical parameter and the second electrical parameter, and determine a positive charging test result for the device under test based on the processing result.

[0095] In some embodiments, the second electrical parameter of the device itself can be obtained through the wireless charging transmitter. In other embodiments, the device under test can send the first electrical parameter of the first wireless charging receiver to the wireless charging transmitter via an amplitude shift keying (ASK) signal. For example, when the test device detects a positive charging instruction, it can send a parameter request to the device under test. After receiving the parameter request, the device under test can send the first electrical parameter of the first wireless charging receiver to the wireless charging transmitter of the test device via an ASK signal.

[0096] In the disclosed embodiment, the test device can also obtain power from the device under test. While the test device is obtaining power from the device under test, the second wireless charging receiver can be controlled to be in an operating state. In this case, the test device can be powered by the device under test. While the device under test is providing power to the test device, a third electrical parameter of the second wireless charging receiver of the test device can be obtained and transmitted to the terminal device.

[0097] In some embodiments, the second wireless charging receiver can send the third electrical parameter to the wireless charging transmitter, and then the wireless charging transmitter sends the third electrical parameter to the terminal device via serial communication. For example, the third electrical parameter can be transmitted via a serial interface. In other optional embodiments, the third electrical parameter can also be sent to the terminal device via other methods, for example, via a wireless network or ZigBee technology.

[0098] In the embodiment of the present disclosure, since the terminal device has data processing capabilities, after sending the third electrical parameter to the terminal device, the terminal device can process the third electrical parameter and determine the reverse charging test result for the device under test based on the processing result.

[0099] In the disclosed embodiment, the positive charging function and the reverse charging function can be integrated into the test device, that is, the test device can both provide power to the device under test and obtain power from the device under test, and upload the obtained test parameters, namely the first electrical parameter, the second electrical parameter, and the third electrical parameter, to the terminal device based on the test device. In this way, during the test process, all test parameters can be obtained based on a single test device, and the full test of the positive charging function and the reverse charging function of the wireless charging of the electronic device can be completed based on the terminal device. The test process is simple and can reduce the possibility of inaccurate test results due to device replacement.

[0100] In other optional embodiments, the first charging coil is further configured to generate electromagnetic induction with a second charging coil included in the device under test when the testing device detects a positive charging instruction, thereby providing electrical energy to the device under test.

[0101] Here, the positive charging instruction can be sent by the terminal device to the test device. For example, after determining that the test device is powered on, the wireless charging transmitter of the test device can be controlled to be in an active state, and the second wireless charging receiver of the test device can be controlled to be in an inactive state.

[0102] In an embodiment of the present disclosure, it is possible to detect whether a first test operation is received based on the terminal device. After the terminal device receives the first test operation, a positive charging instruction can be generated based on the first test operation and the positive charging instruction can be sent to the test device. When the test device receives the positive charging instruction, the first charging coil on the test device can be driven to generate electromagnetic induction with the second charging coil of the device to be tested placed on the test bench of the test device, thereby providing power to the device to be tested, thereby causing the device to be tested to enter a wireless charging state.

[0103] In the embodiment of the present disclosure, when the test device detects a positive charging instruction, it can drive the first charging coil and the second charging coil to generate electromagnetic induction, provide power to the device under test, realize the positive charging function of the device under test, and provide convenience for obtaining electrical parameters during the positive charging process.

[0104] In other optional embodiments, the wireless charging transmitter is further configured to send the reverse charging instruction to the first wireless charging receiver when the test device detects the reverse charging instruction;

[0105] receiving response information corresponding to the reverse charging instruction returned by the first wireless charging receiver, and generating an interrupt signal based on the response information;

[0106] The interrupt signal is used to control the wireless charging transmitter to enter a shutdown state.

[0107] Here, the reverse charging instruction may be sent by the terminal device to the test device. For example, the reverse charging instruction may be automatically generated after the test device completes a positive charging test on the device under test. Alternatively, the reverse charging instruction may be generated based on the second test operation after the terminal device detects whether it has received the second test operation.

[0108] In an embodiment of the present disclosure, after the terminal device generates an anti-charging instruction, the anti-charging instruction can be sent to the test device. When the test device receives the anti-charging instruction, the anti-charging instruction can be sent to the first wireless charging receiver. After receiving the anti-charging instruction, the first wireless charging receiver can generate corresponding response information based on the anti-charging instruction and send the response information to the test device. After receiving the response information, the test device can generate an interrupt signal based on the response information and control the wireless charging transmitter to enter a shutdown state based on the interrupt signal.

[0109] Here, the response information is used to indicate that the first wireless charging receiver has received the reverse charging instruction, and may be a response code, such as a digital code, an alphabetic code, and the like.

[0110] In some embodiments, the test device may send the reverse charging instruction to the first wireless charging receiver via a frequency shift keying (FSK) signal, and the first wireless charging receiver may return response information corresponding to the reverse charging instruction via an ASK signal.

[0111] In an embodiment of the present disclosure, when the test device detects a reverse charging instruction, it can send the reverse charging instruction to the device under test, and control the wireless charging transmitter to enter a closed state based on the response information received from the device under test, thereby terminating the positive charging process of the device under test and providing convenience for entering the reverse charging process.

[0112] In other optional embodiments, the wireless charging transmitter is further configured to generate an enable signal based on the response information, and send the enable signal to the second wireless charging receiver;

[0113] The enable signal is used to enable the second wireless charging receiver to enter a receiving state.

[0114] In an embodiment of the present disclosure, after the terminal device generates an anti-charging instruction, the anti-charging instruction can be sent to the test device. When the test device receives the anti-charging instruction, the anti-charging instruction can be sent to the first wireless charging receiver. After receiving the anti-charging instruction, the first wireless charging receiver can generate corresponding response information based on the anti-charging instruction and send the response information to the test device. After receiving the response information, the test device can generate an enable signal based on the response information and control the second wireless charging receiver to enter a working state based on the enable signal.

[0115] In some embodiments, the response information is used to indicate that the first wireless charging receiver has received the reverse charging instruction, and may be a response code, such as a digital code, an alphabetic code, and the like.

[0116] In an embodiment of the present disclosure, when the test device detects a reverse charging instruction, it can send the reverse charging instruction to the device under test, and control the second wireless charging receiver to enter a working state based on the response information received from the device under test, thereby controlling the device under test to enter a reverse charging process.

[0117] In other optional embodiments, the test device further includes: a bus;

[0118] The wireless charging transmitter is connected to the second wireless charging receiver via the bus;

[0119] The bus is used for signal transmission.

[0120] Figure 3 is a schematic diagram of the structure of a test device according to an exemplary embodiment Figure 3 ,like Figure 3 As shown, the test device 100 further includes a bus 301. In the embodiment of the present disclosure, the connection between the wireless charging transmitter and the second wireless charging receiver is achieved through the bus, which can realize signal transmission between the wireless charging transmitter and the second wireless charging receiver. For example, the transmission of interrupt signals and enable signals can be realized based on the bus.

[0121] Figure 4 is a schematic diagram of a system framework according to an exemplary embodiment. Figure 4 As shown, the system includes: a terminal device 401 , a test device 100 and a device under test 301 . Figure 5 FIG. 1 is a schematic structural diagram of a device under test according to an exemplary embodiment. Figure 5 As shown, the device under test 500 includes: a first wireless charging receiver 501 , a first charging coil 502 and a central processing unit 503 , wherein the first wireless charging receiver 501 is connected to the first charging coil 502 , and the central processing unit 503 is connected to the first wireless charging receiver 501 .

[0122] In an embodiment of the present disclosure, after determining that the test device is powered on, the wireless charging transmitter of the test device can be controlled to be in an active state, and the second wireless charging receiver of the test device can be controlled to be in an off state. That is, after the test device is powered on, the test device operates in a transmit (Tx) mode, the enable signal (Rx1619_EN signal) is pulled high, the second wireless charging receiver (e.g., NU1619 chip) does not work, and the device under test (e.g., the mobile phone under test) is in a receive (Rx) mode. In some embodiments, you can click the start test control on the terminal device (e.g., PC), and place the device under test on the test bench of the test device, and the device under test can enter the wireless charging state.

[0123] During the implementation process, the wireless charging transmitter (e.g., NU1020) can obtain its own second electrical parameters (e.g., input voltage and current), and the device under test can transmit the first electrical parameters (e.g., output current and voltage) of the first wireless charging receiver (e.g., NU1619 chip) to the wireless charging transmitter (e.g., NU1020) on the test device via an ASK signal. After receiving the first electrical parameters, the wireless charging transmitter can upload the first and second electrical parameters to a terminal device (e.g., a PC) via serial communication. The terminal device can calculate the output power of the device under test based on the first electrical parameters, calculate the input power of the test device based on the second electrical parameters, and determine the positive charging test result based on the input power of the test device and the output power of the device under test.

[0124] In other embodiments, after completing the positive charging test, the terminal device may send a reverse charging instruction to the test device. For example, the reverse charging instruction is sent to the wireless charging transmitter (for example, NU1020 chip) of the test device through serial communication, and the wireless charging transmitter sends the reverse charging instruction to the first wireless charging receiver (for example, NU1619 chip) of the device under test through an FSK signal, and the first wireless charging receiver receives the reverse charging instruction through a bus (for example, I 2 C bus) sends a reverse charging instruction to a central processing unit (CPU) of the device under test, so that the CPU of the device under test turns on the reverse charging function of the device under test.

[0125] After the CPU of the device under test receives the reverse charging instruction, it sends the reverse charging instruction to the first wireless charging receiver of the device under test (for example, NU1619 chip) through the bus. The first wireless charging receiver sends the response information (for example, response code) for the reverse charging instruction to the wireless charging transmitter of the test device (for example, NU1020 chip) through the ASK signal. After that, the wireless charging transmitter turns off energy transmission and enables the second wireless charging receiver (for example, NU1619 chip) on the test device to enter the receiving state by pulling up the enable (RX1619_EN) signal. At the same time, the interrupt signal is pulled high to control the wireless charging transmitter (for example, NU1020 chip) to enter the off state.

[0126] When the CPU of the device under test detects that the wireless charging transmitter of the test device enters the off state, that is, when the CPU of the device under test detects that the energy signal of the second wireless charging receiver of the test device becomes low, the reverse charging function is turned on and the device under test starts to send energy to the test device.

[0127] When the device under test provides power to the test device, the third electrical parameter of the second wireless charging receiver (for example, the output current and voltage) can be obtained, and the third electrical parameter can be sent to the terminal device through serial communication.

[0128] For example, the terminal device can obtain parameters and send them to the wireless charging transmitter of the test device through serial communication. The wireless charging transmitter obtains the current and voltage output by the second wireless charging receiver through the bus, and uploads the current and voltage output by the second wireless charging receiver to the terminal device through serial communication. The terminal device can determine the reverse charging test result based on the third electrical parameter.

[0129] In other embodiments, after the test of the device under test is completed, the reverse charging function of the device under test can be disabled, and the test device can continue to provide power to the device under test. For example, after the wireless charging transmitter of the test device detects that the interrupt signal of the second wireless charging receiver has gone low, the test device can be controlled to provide power to the device under test.

[0130] The test equipment in the disclosed embodiments integrates both positive and reverse charging functions. This allows for full testing of both the positive and reverse charging functions of the device under test to be completed through the terminal device, simplifying the testing process and saving testing costs. The technical solution disclosed in this disclosure can be used for production line testing of devices under test (e.g., mobile phones), intercepting issues with the wireless charging function of the device under test and preventing problematic devices from reaching users.

[0131] Figure 6 This is a flow chart of a testing method according to an exemplary embodiment. Figure 1 ,like Figure 6 As shown, the method is applied to a test device, comprising:

[0132] In step 601, when the test device provides power to the device under test, a first electrical parameter of a first wireless charging receiver of the device under test is obtained;

[0133] In step 602, the first electrical parameter and the second electrical parameter of the wireless charging transmitter are sent to a terminal device, so that the terminal device determines a positive charging test result for the device under test based on the first electrical parameter and the second electrical parameter;

[0134] In step 603, when the test device obtains power from the device under test, a third electrical parameter of the second wireless charging receiver of the test device is obtained;

[0135] In step 604, the third electrical parameter is sent to the terminal device, so that the terminal device determines a reverse charging test result for the device under test based on the third electrical parameter.

[0136] Here, both the test device and the device under test are electronic devices with wireless charging capabilities, and the test device is integrated with a test board that includes a wireless charging transmitter, a second wireless charging receiver, and a first charging coil. The device under test can be a terminal device with wireless charging capabilities, such as a mobile terminal. Mobile terminals include mobile phones, laptops, tablets, wearable electronic devices, smart speakers, and the like.

[0137] In the disclosed embodiments, since the test device has a first charging coil and the device under test has a second charging coil, during implementation, the test device can provide power to the device under test, or obtain power from the device under test, through magnetic induction technology. For example, after the test device is powered on, the device under test can be placed on a test bench of the test device. In this way, the first charging coil on the test device and the second charging coil on the device under test can generate electromagnetic induction, thereby causing the device under test to enter a wireless charging state.

[0138] In some embodiments, the wireless charging transmitter includes a NU1020 chip, the second wireless charging receiver includes a NU1619 chip, and the first charging coil includes an MP-A2 wireless charging coil.

[0139] In some embodiments, upon detecting that the test device is powered on, the wireless charging transmitter can be controlled to be in an active state, and the second wireless charging receiver can be controlled to be in an inactive state. In this case, the test device can provide power to the device under test, and while the test device is providing power to the device under test, a first electrical parameter of the first wireless charging receiver of the device under test is obtained, and the first electrical parameter and the second electrical parameter of the wireless charging transmitter are transmitted to the terminal device.

[0140] In some embodiments, the wireless charging transmitter can send the first electrical parameter and the second electrical parameter to the terminal device via serial communication. For example, the first electrical parameter and the second electrical parameter can be transmitted via a serial interface. In other optional embodiments, the first electrical parameter and the second electrical parameter can also be sent to the terminal device in other ways, for example, via a wireless network or ZigBee technology.

[0141] In some embodiments, the terminal device may be an electronic device with data processing capabilities, for example, a mobile terminal or a fixed terminal with a processor. Mobile terminals include mobile phones, laptops, tablet computers, etc. Fixed terminals include personal computers (PCs), etc. In other embodiments, the terminal device may also be a server.

[0142] In the embodiment of the present disclosure, after sending the first electrical parameter and the second electrical parameter to the terminal device, the terminal device may process the first electrical parameter and the second electrical parameter, and determine a positive charging test result for the device under test based on the processing result.

[0143] In some embodiments, the second electrical parameter of the device itself can be obtained through the wireless charging transmitter. In other embodiments, the device under test can send the first electrical parameter of the first wireless charging receiver to the wireless charging transmitter via an amplitude shift keying (ASK) signal. For example, when the test device detects a positive charging instruction, it can send a parameter request to the device under test. After receiving the parameter request, the device under test can send the first electrical parameter of the first wireless charging receiver to the wireless charging transmitter of the test device via an ASK signal.

[0144] In the disclosed embodiment, the test device can also obtain power from the device under test. While the test device is obtaining power from the device under test, the second wireless charging receiver can be controlled to be in an operating state. In this case, the test device can be powered by the device under test. While the device under test is providing power to the test device, a third electrical parameter of the second wireless charging receiver of the test device can be obtained and transmitted to the terminal device.

[0145] In some embodiments, the second wireless charging receiver can send the third electrical parameter to the wireless charging transmitter, and then the wireless charging transmitter sends the third electrical parameter to the terminal device via serial communication. For example, the third electrical parameter can be transmitted via a serial interface. In other optional embodiments, the third electrical parameter can also be sent to the terminal device via other methods, for example, via a wireless network or ZigBee technology.

[0146] In the embodiment of the present disclosure, since the terminal device has data processing capabilities, after sending the third electrical parameter to the terminal device, the terminal device can process the third electrical parameter and determine the reverse charging test result for the device under test based on the processing result.

[0147] In the disclosed embodiment, the positive charging function and the reverse charging function can be integrated into the test device, that is, the test device can both provide power to the device under test and obtain power from the device under test, and upload the obtained test parameters, namely the first electrical parameter, the second electrical parameter, and the third electrical parameter, to the terminal device based on the test device. In this way, during the test process, all test parameters can be obtained based on a single test device, and the full test of the positive charging function and the reverse charging function of the wireless charging of the electronic device can be completed based on the terminal device. The test process is simple and can reduce the possibility of inaccurate test results due to device replacement.

[0148] In other optional embodiments, when a positive charging instruction is detected, the first charging coil of the testing device and the second charging coil of the device under test are driven to generate electromagnetic induction to provide power to the device under test.

[0149] Here, the positive charging instruction can be sent by the terminal device to the test device. For example, after determining that the test device is powered on, the wireless charging transmitter of the test device can be controlled to be in an active state, and the second wireless charging receiver of the test device can be controlled to be in an inactive state.

[0150] In an embodiment of the present disclosure, it is possible to detect whether a first test operation is received based on the terminal device. After the terminal device receives the first test operation, a positive charging instruction can be generated based on the first test operation and the positive charging instruction can be sent to the test device. When the test device receives the positive charging instruction, the first charging coil on the test device can be driven to generate electromagnetic induction with the second charging coil of the device to be tested placed on the test bench of the test device, thereby providing power to the device to be tested, thereby causing the device to be tested to enter a wireless charging state.

[0151] In the embodiment of the present disclosure, when the test device detects a positive charging instruction, it can drive the first charging coil and the second charging coil to generate electromagnetic induction, provide power to the device under test, realize the positive charging function of the device under test, and provide convenience for obtaining electrical parameters during the positive charging process.

[0152] In other optional embodiments, when a reverse charging instruction is detected, the reverse charging instruction is sent to the device under test;

[0153] receiving response information corresponding to the reverse charging instruction returned by the device under test, and generating an interrupt signal based on the response information;

[0154] The interrupt signal is used to control the wireless charging transmitter to enter a shutdown state.

[0155] Here, the reverse charging instruction may be sent by the terminal device to the test device. For example, the reverse charging instruction may be automatically generated after the test device completes a positive charging test on the device under test. Alternatively, the reverse charging instruction may be generated based on the second test operation after the terminal device detects whether it has received the second test operation.

[0156] In an embodiment of the present disclosure, after the terminal device generates an anti-charging instruction, the anti-charging instruction can be sent to the test device. When the test device receives the anti-charging instruction, the anti-charging instruction can be sent to the first wireless charging receiver. After receiving the anti-charging instruction, the first wireless charging receiver can generate corresponding response information based on the anti-charging instruction and send the response information to the test device. After receiving the response information, the test device can generate an interrupt signal based on the response information and control the wireless charging transmitter to enter a shutdown state based on the interrupt signal.

[0157] Here, the response information is used to indicate that the first wireless charging receiver has received the reverse charging instruction, and may be a response code, such as a digital code, an alphabetic code, and the like.

[0158] In some embodiments, the test device may send the reverse charging instruction to the first wireless charging receiver via a frequency shift keying (FSK) signal, and the first wireless charging receiver may return response information corresponding to the reverse charging instruction via an ASK signal.

[0159] In an embodiment of the present disclosure, when the test device detects a reverse charging instruction, it can send the reverse charging instruction to the device under test, and control the wireless charging transmitter to enter a closed state based on the response information received from the device under test, thereby terminating the positive charging process of the device under test and providing convenience for entering the reverse charging process.

[0160] In other optional embodiments, an enable signal is generated based on the response information, and the enable signal is sent to the second wireless charging receiver;

[0161] The enable signal is used to enable the second wireless charging receiver to enter a receiving state.

[0162] In an embodiment of the present disclosure, after the terminal device generates an anti-charging instruction, the anti-charging instruction can be sent to the test device. When the test device receives the anti-charging instruction, the anti-charging instruction can be sent to the first wireless charging receiver. After receiving the anti-charging instruction, the first wireless charging receiver can generate corresponding response information based on the anti-charging instruction and send the response information to the test device. After receiving the response information, the test device can generate an enable signal based on the response information and control the second wireless charging receiver to enter a working state based on the enable signal.

[0163] In some embodiments, the response information is used to indicate that the first wireless charging receiver has received the reverse charging instruction, and may be a response code, such as a digital code, an alphabetic code, and the like.

[0164] In an embodiment of the present disclosure, when the test device detects a reverse charging instruction, it can send the reverse charging instruction to the device under test, and control the second wireless charging receiver to enter a working state based on the response information received from the device under test, thereby controlling the device under test to enter a reverse charging process.

[0165] Figure 7 This is a flow chart of a testing method according to an exemplary embodiment. Figure 2 ,like Figure 7 As shown, the method is applied to a terminal device, comprising:

[0166] In step 701, when the test device provides power to the device under test, a first electrical parameter of a first wireless charging receiver of the device under test and a second electrical parameter of a wireless charging transmitter of the test device are obtained;

[0167] In step 702, a positive charging test result for the device under test is determined based on the first electrical parameter and the second electrical parameter;

[0168] In step 703, when the test device obtains power from the device under test, a third electrical parameter of the second wireless charging receiver of the test device is obtained;

[0169] In step 704, a reverse charging test result for the device under test is determined based on the third electrical parameter.

[0170] In the disclosed embodiments, after the test device is powered on, the wireless charging transmitter of the test device can be controlled to be in an active state, and the second wireless charging receiver of the test device can be controlled to be in a disabled state. Specifically, after the test device is powered on, the test device operates in transmit mode, the enable signal is pulled high, the second wireless charging receiver is disabled, and the device under test is in receive mode. In some embodiments, the test device can be placed on the test bench of the test device, and the device under test can enter the wireless charging state.

[0171] During implementation, the wireless charging transmitter can obtain its own second electrical parameter, and the device under test can transmit the first electrical parameter of the first wireless charging receiver to the wireless charging transmitter on the test device via an ASK signal. After receiving the first electrical parameter, the wireless charging transmitter can upload the first and second electrical parameters to the terminal device via serial communication. The terminal device can calculate the output power of the device under test based on the first electrical parameter, calculate the input power of the test device based on the second electrical parameter, and determine the positive charging test result based on the input power of the test device and the output power of the device under test.

[0172] In other embodiments, after completing the positive charging test, the terminal device may send a reverse charging instruction to the test device. For example, the reverse charging instruction may be sent to the wireless charging transmitter of the test device via serial communication. The wireless charging transmitter may send the reverse charging instruction to the first wireless charging receiver of the device under test via an FSK signal. The first wireless charging receiver may send the reverse charging instruction to the CPU of the device under test via a bus, so that the CPU of the device under test enables the reverse charging function of the device under test.

[0173] After the CPU of the device under test receives the reverse charging instruction, it sends the reverse charging instruction to the first wireless charging receiver of the device under test through the bus. The first wireless charging receiver sends the response information for the reverse charging instruction to the wireless charging transmitter of the test device through the ASK signal. After that, the wireless charging transmitter turns off the energy transmission and enables the second wireless charging receiver on the test device to enter the receiving state by pulling up the enable signal. At the same time, the interrupt signal is pulled high to control the wireless charging transmitter to enter the shutdown state.

[0174] When the CPU of the device under test detects that the wireless charging transmitter of the test device enters the off state, that is, when the CPU of the device under test detects that the energy signal of the second wireless charging receiver of the test device becomes low, the reverse charging function is turned on and the device under test starts to send energy to the test device.

[0175] When the device under test provides power to the test device, the third electrical parameter of the second wireless charging receiver (for example, the output current and voltage) can be obtained, and the third electrical parameter can be sent to the terminal device through serial communication.

[0176] For example, the terminal device can obtain parameters and send them to the wireless charging transmitter of the test device through serial communication. The wireless charging transmitter obtains the current and voltage output by the second wireless charging receiver through the bus, and uploads the current and voltage output by the second wireless charging receiver to the terminal device through serial communication. The terminal device can determine the reverse charging test result based on the third electrical parameter.

[0177] In other embodiments, after the test of the device under test is completed, the reverse charging function of the device under test can be disabled, and the test device can continue to provide power to the device under test. For example, after the wireless charging transmitter of the test device detects that the interrupt signal of the second wireless charging receiver has gone low, the test device can be controlled to provide power to the device under test.

[0181] determining a power input to the test device based on a current value and a voltage of the wireless charging transmitter;

[0182] The positive charge test result is determined based on the power input to the test device and the power output from the device under test.

[0183] In other optional embodiments, determining the positive charging test result based on the power input to the test device and the power output from the device under test includes:

[0184] determining an efficiency of wireless charging of the device under test based on power input to the test device and power output from the device under test;

[0185] The efficiency of wireless charging of the device under test is compared with a first preset standard value, and the positive charging test result is determined according to the comparison result.

[0186] In some embodiments, the efficiency of wireless charging of the device under test can be obtained based on the ratio between the power input to the test device and the power output from the device under test. After obtaining the efficiency of wireless charging of the device under test, the efficiency of wireless charging of the device under test can be compared with a first preset standard value, and a positive charging test result can be determined based on the comparison result.

[0187] For example, if the efficiency of wireless charging of the device under test is greater than or equal to a first preset standard value, it indicates that the positive charging function of the device under test is normal; if the efficiency of wireless charging of the device under test is less than the first preset standard value, it indicates that the positive charging function of the device under test is abnormal. The first preset standard value may be a value obtained through experiments.

[0188] In other embodiments, after the positive charging test result is obtained, a first prompt information may be output, where the first prompt information is used to indicate whether the positive charging function of the device under test is normal or abnormal.

[0189] In other optional embodiments, the third electrical parameter includes: a current value and a voltage value of the second wireless charging receiver;

[0190] The determining, based on the third electrical parameter, a reverse charging test result for the device under test includes:

[0191] determining the power input to the second wireless charging receiver based on the current value and the voltage value of the second wireless charging receiver;

[0192] The reverse charging test result is determined based on the power input to the second wireless charging receiver.

[0194] The power input to the second wireless charging receiver is compared with a second preset standard value, and the positive charging test result is determined according to the comparison result.

[0195] Here, after obtaining the power of the second wireless charging receiver, the power of the second wireless charging receiver may be compared with a second preset standard value, and the reverse charging test result may be determined according to the comparison result.

[0196] For example, if the power of the second wireless charging receiver is greater than or equal to a second preset standard value, it indicates that the reverse charging function of the device under test is normal; if the power of the second wireless charging receiver is less than the second preset standard value, it indicates that the reverse charging function of the device under test is abnormal. The second preset standard value can be a value obtained through experiments.

[0197] In other embodiments, after the positive charging test result is obtained, a second prompt information may be output, where the second prompt information is used to indicate whether the reverse charging function of the device under test is normal or abnormal.

[0198] In the disclosed embodiments, a terminal device can complete all tests of the positive and reverse charging functions of a device under test, simplifying the testing process and reducing testing costs. The disclosed technical solution can also be used for production line testing of devices under test, intercepting issues with the device's wireless charging function and preventing problematic devices from reaching users.
