CHAdeMO vs. Type 1 (J1772)
Comparing 2 standards across 13 specifications. 13 key differences identified.
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.
The SAE J1772 Connector (standardized as IEC 62196 Type 1, commonly called the J-Plug) is the standard single-phase AC charging interface for electric vehicles across North America and Japan. Featuring a 5-pin circular plug layout with an integrated mechanical top latch, it delivers Level 1 (120V / 16A / 1.9 kW) and Level 2 (208–240V / up to 80A / 19.2 kW) power.
