Why this standard matters

CCS1 is the North American DC fast-charging standard combining the SAE J1772 AC connector with two DC pins. It shares DC physical specs with CCS2 but uses a different AC upper section. The rise of NACS has put CCS1 into decline across North America, with most OEMs transitioning during 2024–2026.
