Title:
CHARGING DEVICE TEST SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/062239
Kind Code:
A1
Abstract:
The present application provides a charging device test system and method. The charging device test system comprises a load module, a test board and a charging device, the charging device and the test board forming a circuit by means of the test board, and the test board being used for reporting a test battery voltage to the charging device; and the charging device is used for receiving the test battery voltage, calculating, according to the test battery voltage, the circuit impedance from the charging device to the load module, so as to adjust the operation state of the charging device according to the calculated circuit impedance, and determining whether the charging device enters a protection state, so as to test the protection function of the circuit impedance of the charging device. The difference between the circuit impedance calculated according to the test battery voltage and the reference impedance is greater than a preset impedance, thereby being able to effectively test whether the protection function of the circuit impedance of the charging device is valid, simplifying the operation and having high accuracy.
