CCS1 vs. CHAdeMO
Comparing 2 standards across 13 specifications. 13 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).
CHAdeMO (standardized under JEVS G105 and IEC 62196-3, developed in Japan by TEPCO, Nissan, Mitsubishi, and Subaru in 2010) is the pioneer DC fast-charging connector. Featuring a 10-pin circular plug with dedicated CAN-bus vehicle communication and full hardware-level Vehicle-to-Grid (V2G) and Vehicle-to-Home (V2H) bi-directional power discharge capability.
