What are the differences among the Chinese GB/T, European CCS2, and North American NACS DC charging interfaces?
The three DC interfaces differ in regional standards, mechanical design, and power capability:
1. GB/T 20234.3 (China): The dominant standard in the Chinese market, featuring a 9-pin layout (including 2 high-power DC terminals, 2 auxiliary power pins, CP/CC communication, etc.), supporting up to 1000V/250A. Widely used in Chinese public fast charging stations;
2. CCS2 (Combo 2, Europe): Adds 2 large DC terminals to the Type 2 AC interface, supporting up to 1000V/380A. Widely deployed in Europe, the Middle East, and Australia;
3. NACS (SAE J3400, North America): An open standard originated from Tesla, with a compact form factor integrating AC and DC terminals in one housing, supporting up to 1000V/350A. Major North American automakers are transitioning to this standard.
Selection should be based on the target market and vehicle interface type. DEGSON offers a full product lineup covering GB/T, CCS2, and NACS standards to meet global market demands.
