AC Charger Testing / Field Service
ST-6680B+
GB/T AC EV Charger Comprehensive Tester
Portable GB/T AC charger tester with charge and fault simulation, R2/R3 adjustment, live data acquisition, optional metering and an IP67 field case.

Product Overview
GB/T AC EV Charger Comprehensive Tester
ST-6680B+ is a portable third-party tester for GB/T AC EV chargers. It supports interoperability testing, independent line switching, vehicle-state and fault simulation, live voltage and current acquisition, field acceptance and inspection. The rugged trolley case is designed for outdoor service, while optional battery, GPS, temperature/humidity and 0.05-class metering modules extend the instrument for field and verification workflows.
Key Features
Designed for reliable EV charger validation.
- 01LAN, RS232 and Wi-Fi interfaces support local and remote communication with the tester and PC software.
- 02The trolley-style protective case is waterproof, pressure-resistant, shock-resistant and corrosion-resistant. Its closed-state protection rating is IP67 and its wheels and handle support outdoor mobility.
- 03The tester simulates the charging process and common faults, supports vehicle states with or without the S2 switch, and provides adjustable vehicle-side R2 and R3 resistance.
- 04CC, CP and PE continuity switching can be simulated. Voltage, current and charger parameters are acquired and displayed in real time.
- 05Optional internal battery operation supports sites without external power. Optional GPS and temperature/humidity modules provide time synchronization and precision timing functions.
- 06An optional metering module provides 0.05-class accuracy for higher-precision verification work.
