CCS2 vs. CHAdeMO
Comparing 2 standards across 13 specifications. 13 key differences identified.
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.
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.
