Charging Station Testing Equipment

Test Instrument

This tester supports GB/T/CCS1/CCS2 protocols up to 1000Vdc/260A. Its 7-inch touchscreen enables real-time monitoring of charging parameters and BMS state simulation (PE pin, mechanical switch, insulation faults). Intelligent diagnostics auto-identify faults, reducing maintenance time by 50%. With IP20 rating and multi-protections (over-temperature/power failure cutoff), it operates from –20°C to +80°C. Feedback load cuts energy costs by 40% during testing.
