Large, round four-pin charging plug for rapid charging points only. Generally used with EV marques such as Mitsubishi and Nissan. It can also be used for Vehicle to Grid (V2G); however, it needs two separate sockets and is less powerful than CCS.
Fun fact: CHAdeMO comes from the Japanese phrase “Ocha demo ikagadesu ka?” meaning “How about tea?”. This refers to the futuristic idea that, ultimately, you’ll be able to charge your electric vehicle in the time it takes to drink a refreshing cuppa.
