Professional Overview
As global EV trade expands, the transition between North American CCS1 (PLC communication) and Chinese GB/T (CAN-bus communication) remains a significant technical barrier. Our CCS1 to GB/T Adapter is not a simple physical converter; it is an “Active Bridge.”
Equipped with an internal micro-computer, it handles the complex digital handshake required to synchronize the charging station’s power output with the vehicle’s Battery Management System (BMS). Whether you are importing a BYD Atto 3, NIO ET7, or a Tesla Model 3 (China-spec), this adapter ensures that your vehicle is recognized by the CCS1 station, allowing for seamless high-speed power delivery without protocol errors.

4. Safety & Trustworthiness
Handling 1000V DC power requires industrial-grade safety redundancies. Our adapter is built to protect the vehicle’s high-voltage system:
-
Dual-Point Thermal Guard: Sensors monitor temperatures at both the CCS1 and GB/T contact points. If temperatures exceed 85°C, the adapter triggers a safety throttle; at 90°C, it executes an emergency shutdown.
-
Secure Locking Latch: Features an integrated self-locking mechanism that prevents the adapter from being unplugged while high-current DC is flowing, eliminating the risk of electrical arcing.
-
High-Conductivity Terminals: We utilize 5μm silver plating on all pins to ensure contact resistance remains below 0.5 mΩ, drastically reducing heat generation during 250A sessions.
-
Compliance & Testing: Every unit undergoes a 3200V AC withstand voltage test and insulation resistance check to ensure it exceeds CE and RoHS safety requirements.

6. FAQ
-
Does it require an internal battery? Yes, the logic board is powered by an internal 18650 battery (often sold separately due to shipping regulations) which maintains the communication handshake.
-
Is it compatible with 350kW chargers? Yes. While it can connect to 350kW dispensers, the adapter will safely limit the current to its rated 250A, and the vehicle’s BMS will dictate the final speed.
-
How do I update the firmware? Simply connect the adapter to a PC via the built-in USB port and use our proprietary software to upload the latest compatibility patch.
