The method can be executed by the charging test system of the mobile terminal, specifically by the software integrated in each device included in the charging test system of the mobile terminal. and/or hardware implementation. As shown in Figure 2, the method includes:

Step 201, the charging test device supplies power to the mobile terminal to be tested, collects charging data of the mobile terminal to be tested, and sends the charging data to the control device.

Wherein, the connection between the control device, the charging test device and the mobile terminal to be tested is established based on the USB transfer cable provided by the embodiment of the present invention, and the transfer switch of the USB transfer cable is in the first state.

Exemplarily, the control device in this embodiment may specifically be a computer and other equipment; the mobile terminal may specifically be a terminal such as a mobile phone and a tablet computer; and the charging test device may specifically be a program-controlled power supply.

In this embodiment, the model of the charging test equipment is not specifically limited. General charging test equipment will provide ports for communicating with control equipment, such as general-purpose interface bus (General-PurposeInterface Bus, GPIB) port, USB port, RS-232 port and local area network (Local AreaNetwork, LAN) port, etc., this The embodiment does not specifically limit the communication manner between the charging test device and the control device.

After the operator has connected the control equipment, the charging test equipment and the mobile terminal to be tested, the switch of the USB transfer cable can be placed in the first state. The power supply positive terminal of the power output port of the device is connected, and the ground terminal of the USB port of the mobile terminal to be tested is connected to the ground terminal of the power output port of the charging test equipment, and the data positive terminal and data negative terminal of the USB port of the mobile terminal to be tested are short catch. The operator can operate on the control device or the charging test device to control the output voltage of the charging test device, supply power to the mobile terminal to be tested, and collect charging data of the mobile terminal to be tested while supplying power. The charging data may specifically include data such as current data, voltage data, and charging time. After the charging test device collects the charging data of the mobile terminal to be tested, it sends it to the control device.

Step 202, the control device determines the test result information according to the charging data, and sends the test result information to the mobile terminal to be tested.

Wherein, the preset charging current range varies with the specific configuration and model of the mobile terminal to be tested, and the specific range is not limited in this embodiment. There are many ways to determine the preset charging current range, for example, it can be determined according to the percentage of the standard charging current of the mobile terminal to be tested, such as 40% to 100% of the standard charging current.

Further, the test failure information may also include a failure type. For example, during the charging test of the mobile terminal, various failures may occur, which may cause the test to fail. The failure type area can be analyzed according to the charging current, so as to distinguish the type of failure and give a prompt, which is convenient for the production line to judge. For example, the first type, when the charging current is always 0, it is judged that the charging path is open or the contact is abnormal; the second type, when the charging current is greater than 3.5A, it is judged that the charging path is short-circuited (2A standard charge); the third type, When the charging current is always less than 500mA, it is determined that non-standard battery charging is recognized.

After the receiving process of the charging data by the control device is completed, or after the test result information is analyzed, the operator can be prompted, and the operator can switch the switch of the USB transfer cable to the second state.

The control device sends the test result information to the mobile terminal to be tested based on the USB connection.

Step 203 , the mobile terminal to be tested determines the flag bit value corresponding to the test result information according to the received test result information, and writes the determined flag bit value into the test result flag bit.

Exemplarily, if the test result information is classified into test success and test failure, the flag bit value corresponding to test success is 1, and the flag bit value corresponding to test failure is 0. When the test result information received by the mobile terminal to be tested from the control device is a successful test, "1" is written into the test result flag for indicating whether the test is successful or not; if the received test result information is a test failure, Then write "0" into the test result flag bit used to indicate whether the test is successful or not. It can be understood that a default value may be set on the flag of the test result, and when the value of the flag determined by the mobile terminal to be tested is consistent with the default value, it may or may not be rewritten.

Exemplarily, as described above, when the charging test fails, there may be different failure types, and the mobile terminal under test can determine the flag value corresponding to the failure type according to the received different test result information, and use the determined The value of the flag bit is written to the test result flag bit indicating the type of failure. For example, the test result flag used to indicate the type of failure has two bits, "01" indicates the first type of failure, "10" indicates the second type of failure, and "11" indicates the third type of failure.
