Rabbit hole here.
According to Tesla,
V2 is 145kW (now ~150kW) as of March 2019.
Introducing V3 Supercharging

But yeah, I guess we have to have someone carefully define all the types (I don't keep track of what the difference is between V1 & V2, and what that means!). The distinction that we were trying to make, in any case, was whether this was going to be 72kW, 150kW or 250kW. Maybe we should just speak in those terms.
I think (hope) we can assume that any new Supercharger with a pedestal like this is going to be 250kW (unambiguously V3 I guess) and there is no reason they would install a 150kW Supercharger (V1 or V2 I guess are both 150kW, according to Wikipedia, and apparently Tesla) ever again (even if there were power limits at the site). And we've ruled out 72kW (?) chargers here (based on pedestal). I suppose logically 72kW would be V2 since they came out after the first 150kW (then 120kW) chargers, but that is apparently not correct. Shrug. They appear to just be called Urban Superchargers.
I'm sure someone who is fastidious about this nomenclature can correct me.
