The CHAdeMO connector is a DC fast-charging standard, primarily used in electric cars in Japan. (Click here for the full list of all countries and the charging connectors they use)
The CHAdeMO charging system was initially developed by Japanese automakers and released before CCS.
CHAdeMO chargers can provide up to 400 amps and 1000 volts DC, delivering a maximum power output of 400 kW. For ultra-rapid charging, the CHAdeMO system requires liquid-cooled cables to avoid damage caused by overheating. Inside those cables there are circulation channels containing a liquid coolant that absorbs and dissipates heat. The liquid cooling process involves a closed-loop system in which the coolant travels back and forth between the connector and the cooling unit of the charger.
