It was designed by VW I think, who handed it over to other car companies so there could be a universal connector.

The reason it's bigger is because it supports 3-phase power, which NACS does not. 3-phase power is a big thing in Europe.

The CCS Type 2 plug was designed by Mennekes - it's even referred to as "Mennekes plug" in some places.
I stand corrected! Thanks
This is very true about 3 phase, but I have heard that there is interest in it being used in EU for AC charging in public garages because it can handle anything up to 277 volts vs J1772 which can only do 208/240. So they can give it 1 of the 3 phases @ 220V and it will work unlike J1772. Allegedly.

But I kind of doubt it will go anywhere when they've been forcing CCS2 on everyone.

The CCS2 AC-only connector (the one for normal charging at home, destination charging and so on) already supports 3-phase with up to 480V phase-to-phase, up to 22kW. It's larger than the NACS connector — there are two additional large pins — but not unwieldy.
so much so that I have a 22kW 3 phase charger at home. (AC, type 2)
3 phase is stupid. DC or bust.
Do you know what you are talking about. Can't decide whether you are joking or whether you really think people should charge via DC in their homes
