AC Charger Testing / Field Service
ST-6680B+
GB/T AC EV Charger Comprehensive Tester
Test GB/T AC chargers with the portable ST-6680B+: 440 V / 63 A sockets, vehicle-state and fault simulation, adjustable R2/R3 and optional metering.

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.
Choose ST-6680B+ for GB/T AC charger development, factory acceptance and field inspection. Adjustable R2/R3 resistance and CC/CP/PE switching reproduce vehicle states and faults, while live measurements help document charger behavior. Specify the metering accuracy and field accessories needed for your procedure.
Choose the right test configuration
Interface and workflow
GB/T AC charger testing with two AC 440 V / 63 A sockets. For Type 2 or SAE J1772 sites, select the corresponding regional tester.
External load and connection limits
No built-in load; external load connection up to 63 A. Confirm voltage, phase arrangement, cables and load controls for sustained charging tests.
Options and accessories
Confirm optional 0.05-class metering, internal battery, GPS and environmental modules. IP67 applies to the closed protective case.
Procurement checklist
Confirm the delivered configuration before ordering
Interface and standards
Confirm the connector, market, protocol and exact standard editions required by the charger and test plan.
Electrical and load path
Separate socket, cable and measurement ratings from the source or external load used during sustained power tests.
Evidence and options
List required metering accuracy, message or waveform capture, fault cases, report fields and optional modules.
Acceptance and support
Agree supplied accessories, software, factory acceptance checks, commissioning, training and support boundaries.
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.

Product FAQ
Common questions about ST-6680B+
Does ST-6680B+ test European or North American AC connectors?
This model is configured for GB/T AC chargers. Choose ST-6680EA-AC for Type 2 or ST-6680UA-AC for Type 1 / SAE J1772, and confirm the exact connector before ordering.
Is a power load included?
No built-in load is included. The external-load connection supports up to 63 A; specify the compatible load, phase arrangement and accessories separately.
Are precision metering and battery operation standard?
The 0.05-class metering module and internal battery are optional, as are GPS and temperature/humidity modules. Confirm included functions and accessories in the quotation.
