North American Charging Standard (NACS): Simplifying EV Charging with Faster Power Delivery
NACS (SAE J3400), originally Tesla proprietary connector, has become an industry-standard EV charging system in North America after being opened in 2022. It integrates AC and DC charging into a single compact connector, supporting high-voltage fast charging up to 1000V and about 350 kW. Compared with CCS1, it simplifies design, improves usability, and enhances interoperability. Standardized by SAE International and widely adopted by automakers and charging networks, NACS is reshaping EV infrastructure toward a unified, efficient charging ecosystem, driving rapid market transition in EV charging.
