In this article from InsideEV’s, it says the 250 kW charging speed is accomplished because of the higher amperage that it can take - 600 amps, which allows for the higher charging speed without resorting to 800 volts.


Other than cost, why would they decided to go with 400 amps, instead of 800? CCS chargers usually are limited to 350 amps, so you’ll need to find one that’s higher rated, to take advantage of the 250 kW.

Hello,

my take is that a 400V architecture is highly compatible with a 3-phase AC domestic system, which allows the EX90 to easily be used as a "home battery" as well, given the proper hardware is in place (two-way charger).
So this is probably the first serious attempt by any car manufacturer at the EV-to-Home and EV-to-EV opportunities.

Ford's also a car company that's trying to do that with the Lightning. Which also uses a 400V architecture.
