CCS2 vs. Type 1 (J1772)
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.
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.
