Two versions exist, different in North America and Europe, the rest of the world uses one of the versions depending on the market.
The benefits of the Combined Charging System (CCS):
CHAdeMO is the trade name of a quick charging method for battery electric vehicles delivering up to 62.5 kW of high-voltage direct current via a special electrical connector. It is proposed as a global industry standard by an association of the same name.
Because CHAdeMO ports do not support AC charging, cars must have two charging ports – one for AC Level 2, the other for CHAdeMO
Two versions (different in North America and Europe/rest of the world)
The Tesla Supercharger system uses a single port supporting, using a slender cable and charging connector, every possible charging situation one can think of:
It means a Tesla Model S or Model X owner can get rapid charging in a wide range of situations.
Tesla Motors also sells an add-on adapter allowing a Model S/X owner to recharge at a CHAdeMO station.
Tesla Motors does not sell any kind of adapter allowing owners of CHAdeMO or CCS cars to recharge at a Supercharger station, however.
