Performance testing of EV cooling and charging gun
China [CN] With the rise of the charging pile industry, charging guns as supporting equipment have also developed rapidly. As a charging equipment, the core function of the charging gun is to provide electric energy for charging electric vehicles, so its performance is related to charging efficiency and safety. So after the design of the charging gun is completed, what performance tests need to be done to ensure that the performance of the charging gun is qualified?
Liquid-cooled charging gun testing items and standards: 1. Appearance inspection: including whether the appearance of the charging gun is intact and whether there are any deformation, damage, etc.
2. Insulation resistance test: Test the insulation performance of the charging gun to ensure that it can work safely under high voltage.
3. Electrical performance testing: including output voltage, current stability testing, input power testing, etc. to verify the charging performance of the charging gun, etc.
Because liquid-cooled charging guns are widely used in high-power fast charging, more attention must be paid to the performance testing of liquid-cooled charging guns to ensure product qualification and safety.
