Not feasible on even 240 Volt AC at all, would have to be high voltage all the way to the charger as the cabling is unworkable. Its completely impractical otherwise and its going to require big changes to the grid.
Presumably that would be at charging stations, not at home. Those would be located in commercial areas where they could get the kind of power feed that medium to large buildings get, which is typically 3 phase 13800 V, and can be thousands of kW.
