Description

Overview
The ET-19 adapter enables GB/T vehicles to fast-charge at CCS2 DC stations. It covers 200–1000 V DC (with a 50–150 V low-voltage option) and 0–200 A output, up to 250 A peak. Protocol support includes DIN 70121/ISO 15118-2 on the CCS2 side and GB/T 27930 on the EV side. The unit is IP54-rated, operates from −20 °C to 60 °C, and provides mechanical locks on both CCS2 and GB/T ends for secure connections.

Key Features
• Wide operating window: 200–1000 V DC, 0–250 A
• Cross-standard communications: CCS2 (DIN 70121/ISO 15118-2) to GB/T (GB/T 27930)
• Safety: 112 °C over-temperature shutdown; mechanical locks on both sides
• Clear LED feedback: power-on, handshake, charging, low battery, comms error, EV refusal, abnormal stop
• Standby power: two 18650 cells; auto-charged during EV charging; Type-C 5 V for diagnostics/firmware/emergency top-up
• Durable build: IP54 enclosure; approx. 310 × 190 × 85 mm; ~1.9 kg; −20 °C to 60 °C operating range

Operation Notes
• Connection order can be charger → adapter → EV or EV → adapter → charger; ensure connectors lock in place
• Charging can be stopped at the charger, at the vehicle, or via the adapter’s control
• If the internal battery is low, briefly power the adapter via the Type-C port before use

Use Cases
• Cross-standard DC charging for GB/T EVs at CCS2 stations
• Fleet depots and rental operations that need multi-standard compatibility
• Backup and travel scenarios across mixed charging networks
