Tesla opening Superchargers to CCS cars: a guess at 920V support

[DeaneG]

I had an insight/guess about Tesla's opening their superchargers to CCS vehicles: they'll increase maximum charging voltage from 450V to 920V at the same time, a least for CCS-connected cars. My reasoning:

1) Tesla is using federal funds to build and install their new V4 superchargers
2) Federal funds require CCS at 150kW minimum per station
3) CCS standards mandates a minimum of 200V-920V voltage compliance range for 150kW stations

Tesla's future models could make good use of 900V+ charging too.

Why couldn’t they just add CCS to their 400v chargers and offer the minimum 150Kw the government requires?

It’d be great if the new V4 chargers are 900v but we know Tesla gets speeds of 250Kw on its 400v chargers and there’s more 400v cars on the market than 800v+. Just means that anyone on 800v+ cars will
Be limited to 50Kw (Lucid) to 150Kw (Taycan) and I don’t see Elon going out of his way to double the voltage to chargers if he can get the money using 400v chargers

Because CCS standards require 200-920V voltage output range on 150kW+ charging stations. 400V does not meet the CCS standard except for legacy 50kW stations, which are not to be installed past 2023.

Ohhh I thought it just meant pick an number between that range and you’re good to go
