What is the difference between CCS2, Type 2 and CHAdeMO chargers?

Type2 - An AC slow charging connector only suited for hybrid PHEV and also full BEV cars with CCS ports.

CCS2 - A DC charging connector usually at DCFC chargers with (Combined Charging System) that can allow EV cars to use either a CCS2 (fast)/ Type2 (slow) charging if necessary.

CHAdeMO -A DC connector only for Japanese EV cars like Nissan Leaf & incompatible with Type2/CCS2 port so it's quite rare. Available only at DCFC units & not AC wall chargers.
