[0002] At present, the time test of the battery disconnection delay function is all manually tested. One person presses the battery activation disconnection button in the driver's cab, and one person observes the suction and disconnection states of the battery activation relay in the passenger compartment control cabinet with the naked eye. When the coil of the battery activation disconnection relay is sucked in, the stopwatch is manually operated to start timing, and at the same time, the state of the battery activation connection relay is observed. When the coil of the battery activation connection relay is disconnected, the stopwatch stops recording. The tested time is the battery activation delay disconnection time. This manual test method by the naked eye cannot accurately test the battery delay power-off time, and there are large errors in the test results. It is necessary to repeatedly test and adjust the delay disconnection time until the time data meets the test requirements. At the same time, at least two people are required to cooperate in the operation, wasting human resources. Content of the Utility Model

The signal acquisition module acquires the disconnection signal, and the timing module stops timing. The test personnel can directly and clearly observe the delay time of the vehicle battery activation and power-off through the digital display screen of the device. The test results can be viewed up to 6 decimal places. Data can also be saved through the acquisition module, which is convenient for data recording and future search.
