Direct Answer
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 Vehicle-to-Grid (V2G) Pioneer
Developed after the 2011 Fukushima earthquake in Japan, CHAdeMO was designed from day one with bi-directional V2G/V2H power export. While CCS and NACS required years of complex software standards (ISO 15118-20) to enable bidirectional charging, any standard Nissan Leaf with a CHAdeMO port can plug into a bidirectional home inverter to power a house for several days.
