CCS1 vs. CCS2
Comparing 2 standards across 11 specifications. 11 key differences identified.
CCS Combo 1 (standardized under SAE J1772 and IEC 62196-3) combines the upper 5-pin J1772 AC inlet with two large dedicated DC power pins below into a single vehicle inlet. Enabling DC fast-charging up to 350 kW (500A @ 1000V DC) using High-Level Communication (HLC) over HomePlug Green PHY Power Line Communication (PLC).
CCS Combo 2 (standardized under IEC 62196-3 and mandated across the European Union) combines the upper 7-pin Type 2 Mennekes inlet with two heavy DC power pins below. Supporting up to 350 kW to 500 kW DC fast-charging (500A @ 1000V DC) alongside native 3-phase AC charging, it is the dominant global fast-charging standard outside North America.
