The charging speed falls so quick it makes close to zero difference in charging time. You get 3 minutes of high kw charging then it drops like a rock, sometimes even lower than the 400v cars..
800 volts simply cuts the current in half between the charger and the car. At the per battery cell level, there is no difference.
