For context, North America's current "standard" is CCS1, which is not the same as Europe, which uses CCS2. So North America already has its own weird plug. The Tesla plug is definitely better from a usability perspective. Very curious to see if there is a major technical advantage for one or the other.



Ccs1 vs 2 comes down to the fact that the base plug (the ac part) has to be different between the two. Europe supports 3 phase because it's common there, while the NA plug doesn't, because 3 phase is unheard of in residential installations, and it has to support 120 level 1 charging.


Huh? CCS1, CCS2 and NACS are DC. You are probably thinking Type 2 (Europe) which is indeed 3 phase and j1772 (US) which is single phase.


Your distinction doesn't matter. They're talking about the plug/socket shape, which is shared between DC and AC standards.


Look up the difference between CCS1 and 2. It's just J1772 vs Type 2. The DC part is the same.


Doesn't seem like it has to be different, right? The Tesla/"NACS" plug supports three-phase.


How? Are you sure?

It has two big power pins, one smaller pin dedicated to ground, and two tiny pins that look completely unsuited for power.

There's a "mobile connector" that can convert 3 phase, but that has an entirely different plug on the wall side.


I think it doesn't actually, nevermind.


In the US Tesla uses its own proprietary connector, in Europe they use the Mennekes plug.

Hence why they are calling this the "North American charging standard."
