Does anyone have better than just-a-guess information (until Nov. 21st) as to what the maximum Amp draw that the "Cyber-Truck" will want for its on-board charger?
[i.e.: NOT to be confused with the box on the wall that is more properly referred to as an EVSE.]
What I would like to know, for planning my future installations, is:
What the maximum amps I should (have) plan(ed) for at 240 volts, single phase?
Here is part of why I am asking...
I installed a 1.25" SCH 80 conduit out to a post in my driveway. I also have two sets of THWN-2 conductors waiting to go into that conduit: #6 for the NEMA 6-50 receptacle, #4 for the larger permanently mounted EVSE (probably ~100Amp ckt.) & one green #8 for the ground.
Then I found out about NFPA-70 (the NEC) Article 625.44(B)(2):
(On a related note, by now we all should know about NEC Article 612.40 and the 125% and/or 80% rule.)
So, back to the #4 conductors... I don't want to pull them in just yet, as I do not want to create a not-yet-necessary splice in the "Temporary RV Power Outlet Box". Which really boils down to...
I guess I've already thrown the dice on that account.
Now it's just a matter of buying the model Y and/or Truck, and buying/installing a HPWC.

Note:
I am aware that _TODAY_, the largest capacity (on-board) charger that Tesla sells is a 11.52 kW (48 amp @ 240 volts, single phase). I am also aware that in the past, 22kW/91.666Amp (for the 2016 & earlier dual charger version), and 16.5kW/68.75Amps HAD BEEN the largest size chargers that were available.

"(2) It is intended for connection to receptacle outlets rated no more than 50 amperes"
Uhhhh WHAT? It appears that the 2017 edition slipped in a limit such that 60 amp receptacles can no longer approved for use with an EVSE. Huh. I guess my future proofing, by getting one size larger conductors (#6AWG) for a 60 amp receptacle, is now only to be used for reducing voltage drop. Oh well. (On a related note, by now we all should know about NEC Article 612.40 and the 125% and/or 80% rule.)

Do I think that the 19.2 kW capacity (80a on 100a ckt.) is all I will need for a Tesla "Cyber Truck" (or whatever it ends up being called) ???
