According to Jason Hughes, V3 Superchargers are 800 V, but now that we learned that there is a 500 V and a 1000 V version of NACS, it probably needs the cable to be replaced
The biggest question for me is, if Tesla will upgrade V3 to 800 V, why they didn't start doing already in new installs? Each day it passes it's more and more chargers that will be needed to be retrofitted
Another possibility is that V3 are 800 V and 500 V of nice can do low 800 V ish, but not 1000 V, which also doesn't make sense
Cybertruck is likely higher voltage, but what does this means? They won't be compatible with existing V3? No way in hell. Or that they have a pack splitting contactors to switch from 400 V to 800 V? Also doesn't make sense because adding complexity isn't the Tesla way
Cybertruck deliveries should start this quarter, there is no time to retrofit enough V3 stations to not make travelling a pain with it, and none of the options above makes much sense, so I'm really curious how it will work
