CHAdeMO
A Japanese DC fast-charging standard with its own separate connector, now giving way to CCS2 in Europe.
Technical level:Intermediate
CHAdeMO was one of the first DC fast-charging standards and is found mainly on older Japanese electric cars and plug-in hybrids. The plug is large and round, and the car usually has a second, separate inlet for AC charging.
Most CHAdeMO stations deliver about 50 kW. As new public stations in Europe are increasingly installed with CCS2 only, coverage for these vehicles is gradually shrinking.
If you drive a car with CHAdeMO, check in the network's app that the station actually has a CHAdeMO cable before setting off on a long trip, and do not rely on adapters that the vehicle manufacturer has not approved.
