Questions & Answers
Q: What is for vehicle test unit:
A: The whole vehicle test is mainly through the slow-charge charging gun and the fast-charge charging gun to the slow-charge charging socket, fast-charge charging socket, and the connected vehicle charger, power battery and other parts of the interface safety test, the main test items are available DC withstand voltage, insulation resistance, ground resistance, leakage current (slow charging port); the main purpose is to detect the safety performance of the charging socket and the interface of the part connected to it; the vehicle needs to be powered off during the test to ensure that all power and electronics on the vehicle The switch is in an inactive state.
1. Slow charging function detection
The slow charge function detection is to detect the slow charging performance of new energy vehicles. The tester charges the new energy vehicles through the slow charge charging interface to detect the charging status of the vehicle, including connection confirmation during AC charging, charging ready, starting and charging Phase, end of normal charging, PWM duty cycle change and current testing.
According to the function of confirming the charging connection, the security checker also adds the function of confirming the connection between the charging gun and the charging socket of the high-voltage test item. When the charging gun is plugged into the car test socket, the security checker will first confirm whether the connection is normal. High pressure detection.
