EU & UL Standard Auto AC Charging Gun Comprehensive Test System
This automated test system performs comprehensive functional testing of AC charging plugs and inlets compliant with GB (China), EU, and UL standards. Featuring QR code-based product identification, automatic data saving, and direct printing of qualified results, it enables full-test automation in a single cycle—significantly improving testing efficiency while reducing labor costs for high-volume manufacturing environments.
Key Testing Functions
- Wire breakage, continuity, short circuit, and wiring sequence verification
- Main conductor continuity resistance measurement
- Built-in resistance measurement (with button pressed/unpressed states)
- Current-carrying capacity and voltage drop analysis
- Insulation resistance testing
- Dielectric withstand (hipot) testing
- Thermistor (temperature sensor) resistance measurement
