Connector types

CHAdeMO

CHAdeMO is a DC fast-charging system with its own vehicle connector and communication protocol. It was developed in Japan and has been used by vehicles including earlier Nissan and Mitsubishi electric models. CHAdeMO is standardised within the IEC 61851 and IEC 62196 families. It also supported bidirectional charging early in the development of commercial vehicle-to-grid systems. The specification is still being developed. CHAdeMO 2.1 was released in May 2026 and raises the specified charging current to 800 A, with support for Plug & Charge functions among the changes. The installed public network still includes many chargers built to earlier CHAdeMO versions.
