[0010] In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the described exemplary embodiments. However, it is clear to those skilled in the art that the described embodiments may be practiced without some or all of these specific details. In the described exemplary embodiments, well-known structures or processing steps are not described in detail in order to avoid unnecessarily obscuring the concepts of the present disclosure.

[0011] The blocks in each block diagram shown below can be implemented by hardware, software, firmware or any combination thereof to implement the principles of the present disclosure. It should be understood by those skilled in the art that the blocks described in each block diagram can be combined or divided into sub-blocks to implement the principles of the present disclosure.

[0012] The steps of the method presented in this disclosure are intended to be illustrative. In certain embodiments, the method can be completed with one or more additional steps not described and / or completed without the one or more steps discussed. In addition, the order in which the steps of the method are illustrated and described is not intended to be restrictive.

[0013] Generally speaking, during the vehicle production process, it is necessary to perform a high voltage test on the high voltage battery of the vehicle in order to ensure that the performance of the high voltage battery of the vehicle meets the specified standards. Generally, existing special test equipment (e.g., a high voltage tester) can be used to perform a high voltage test on the high voltage battery of the vehicle. When using, for example, a high voltage tester to test the high voltage battery of the vehicle, the tester needs to always hold a special high voltage test gun to connect the electrode port of the high voltage tester to the electrode port of the high voltage battery. Since the high voltage test of the high voltage battery of the vehicle is carried out under a high voltage environment, when the high voltage test is performed in the above manner, the tester may face the risk of electric shock. In addition, when the high voltage test is performed in the above manner, the tester needs to manually operate the high voltage tester to perform operations such as setting test parameters and starting / stopping the high voltage tester. In addition, since the test results are only displayed via the display screen of the high voltage tester when the high voltage test is performed in the above manner and cannot be automatically stored in the high voltage tester, the tester is required to manually record the results of the high voltage test, which may take more time and may have the risk of incorrect recording.

[0014] Therefore, the present disclosure provides a new test method for performing a high voltage test on a high voltage battery of a vehicle. By means of the test method, electric shock to the tester can be effectively prevented, and the high voltage test can be automatically performed and the result of the high voltage test can be automatically recorded.

[0015] Next, first refer to Figure 1 A high voltage test system 100 for performing a high voltage test on a high voltage battery of a vehicle according to the present disclosure will be described.

[0016] Figure 1 is an exemplary block diagram illustrating a high voltage test system 100 for performing a high voltage test on a high voltage battery of a vehicle according to some embodiments of the present disclosure. Figure 1 As shown, the high voltage test system 100 may include a control device 110 and a high voltage test device 120. The control device 110 may receive a test scheme for high voltage testing selected by a tester. In some embodiments, the above test scheme is pre-compiled and stored. In addition, the control device 110 may send the selected test scheme to the high voltage test device 120, which is connected to the high voltage battery through a wiring harness via a port. The high voltage test device 120 may perform a high voltage test on the high voltage battery 130 according to the test scheme received from the control device 110.

[0017] In the present disclosure, the control device 110 may be, for example, a personal computer, but it should be understood that the control device 110 is not limited thereto, and the control device 110 may also be a tablet computer or other device.

[0018] The following will further describe in detail Figure 1 The operation of the control device 110 and the high voltage testing device 120 are shown.

[0019] Figure 2 is an exemplary flow chart illustrating a testing method 200 for performing a high voltage test on a high voltage battery of a vehicle according to some embodiments of the present disclosure.

[0020] The method 200 starts from step S210, where a test scheme for high voltage testing selected by a tester is received via the control device 110, and the test scheme is pre-compiled and stored. For example, the test scheme for high voltage testing selected by the tester can be received via the graphical user interface 300 of the control device 110 described later. In some embodiments, for different modules of the high voltage battery, the tester can pre-compile different test schemes using a known programming language and the compiled test schemes can be stored in the control device 110. It is noted that the compiled test scheme cannot be arbitrarily tampered with by the tester during the high voltage test.

[0021] The method 200 proceeds to step S220, where the test scheme selected by the tester at step S210 is sent from the control device 110 to the high-voltage test device 120, which is connected to the high-voltage battery 130 via a port through a wiring harness. For example, the control device 110 may send the test scheme selected by the tester at step S210 to the high-voltage test device 120 via a network port. In some embodiments, for example, the high-voltage test device 120 is connected to the high-voltage battery 130 of the vehicle via a specific wiring harness via a port reserved on the high-voltage test device 120. The above-mentioned specific wiring harness is prepared in advance by, for example, a tester and is adapted to the high-voltage test device 120 and the high-voltage battery 130.

[0022] The method 200 proceeds to step S230, where the high-voltage test device 120 performs a high-voltage test on the high-voltage battery 130 according to the test plan received from the control device 110 at step S220. Since the test plan is pre-compiled, during the entire high-voltage test process, the high-voltage test device 120 can automatically perform a high-voltage test on the high-voltage battery 130 according to the received test plan, without the need for the tester to manually operate the high-voltage test device 120.

[0023] Based on the above method 200, since the tester can control the high-voltage test device 120 to perform a high-voltage test on the high-voltage battery 130 through the control device 110, without always holding a dedicated high-voltage test gun to connect the electrode port of the high-voltage tester to the electrode port of the high-voltage battery, this can effectively prevent the tester from getting an electric shock and improve the safety during the high-voltage test. In addition, since the test scheme is pre-compiled and cannot be arbitrarily tampered with during the test, the high-voltage test of the high-voltage battery can be automatically performed, saving the time required to perform the high-voltage test and ensuring the correctness of the entire high-voltage test process.

[0024] In some embodiments, the method 200 may also include receiving test result data from the high voltage test device 120 in real time via the control device 110, and automatically generating a test report, wherein the test result data includes a test voltage and a test current. For example, the control device 110 may receive test result data such as a test voltage and a test current from the high voltage test device 120 in real time, and store the received test result data in, for example, an Excel spreadsheet, thereby generating a corresponding test report. In some embodiments, the generated test report is automatically stored in the control device 110 after the high voltage test is completed. In this way, the tester does not need to manually record the test result data, thereby improving the efficiency of the high voltage test and reducing the risk of erroneous recording by the tester.

[0025] In some embodiments, in addition to the above-mentioned test result data such as test voltage and test current, the control device 110 may also receive data such as the identifier of the tested high-voltage battery, the test time, and the test result from the high-voltage test device 120, and store such data and the test result data (collectively referred to as data about the high-voltage battery) together in, for example, an Excel spreadsheet, thereby generating a corresponding test report. In some embodiments, the identifier of the high-voltage battery may be, for example, the serial number of the high-voltage battery. The test time may be, for example, the time when the high-voltage test starts or ends. The test result may be, for example, information indicating whether the high-voltage test has passed or failed.

[0026] In some embodiments, for example, the above-mentioned various data of multiple high-voltage batteries (for example, the identifier of the tested high-voltage battery, the test time, the test voltage, the test current, and the test result) can be stored in the same test report, so as to facilitate the tester to find the relevant data. During the search process, since each high-voltage battery has a unique identifier (for example, a number), the tester can quickly find the above-mentioned various data about the high-voltage battery being searched by, for example, searching for the identifier of the required high-voltage battery in the test report.

[0027] Figure 3 is an illustrative diagram illustrating a graphical user interface 300 of a control device 110 according to some embodiments of the present disclosure.

The completion state may indicate that the high voltage test device 120 has completed the high voltage test. The aborted state may indicate that the high voltage test performed by the high voltage test device 120 is interrupted.

For example, in the case where the tester selects the start button, the control device 110 may control the high-voltage test device 120 so that it starts to perform the high-voltage test. In addition, in the case where the tester selects the stop button, the control device 110 may control the high-voltage test device 120 so that it stops performing the high-voltage test.

[0032] In some embodiments, information about the high voltage test device 120 may be displayed in the area 303. For example, the information about the high voltage test device 120 may include the manufacturer of the high voltage test device 120, the type of the high voltage test device, the ID no of the high voltage test device, and the version of the high voltage test device. The information about the high voltage test device 120 may be automatically displayed in the area 303 after the control device 110 is connected to the high voltage test device 120.

[0033] In some embodiments, information about the tested high-voltage battery may be displayed in area 304.

In some embodiments, the running state of the test scheme may include, for example, initialization (INIT), in execution, and completed, etc. In addition, the test stage may include a voltage increase stage, a voltage maintenance stage, and a voltage drop stage. In some embodiments, different test stages may be represented by different numbers (e.g., 0, 1, 2, etc.). In addition, the test method of the high-voltage battery may include various known battery test methods.

[0035] It should be understood that the graphical user interface 300 of the control device 110 is merely exemplary and not restrictive. For example, more columns or buttons may be added to the graphical user interface 300, or some columns or buttons may be deleted as needed.

[0036] As described above, the present disclosure provides a new test method for performing a high-voltage test on a high-voltage battery of a vehicle. By using the test method according to the present disclosure, it is possible to avoid the tester holding a high-voltage test gun to connect the electrode port of the high-voltage tester to the electrode port of the high-voltage battery, thereby effectively preventing the tester from getting an electric shock and improving the safety during the high-voltage test. In addition, according to the test method of the present disclosure, the control device can control the high-voltage test device to automatically perform a high-voltage test based on the test plan and can also automatically store the test result data, thereby saving the time required to perform the high-voltage test and improving the test efficiency, while also reducing the risk of erroneous recording by the tester. In addition, since the test plan is pre-compiled and cannot be arbitrarily tampered with during the test process, it is possible to avoid the tester manually setting the test parameters, thereby reducing the time required to perform the high-voltage test and ensuring the correctness of the test process.
