Specifications indicate that the car's internal charger is 40 amp, which is clearly 9.6 kW at 240 V. Intriguingly, a decal inside the charging compartment's door of the car at dealer that I just examined indicates an option of 3-phase AC at 400 V (presumably this is the standard that Europe and most of the rest of the world outside of North America uses of three phases at 230 V phase-to-phase, 400 V to ground). Setting aside the difficulty of getting 230/400 V power in USA and the need for an inlet with pins for all three phases, this suggests that the car could charge at up to 48 kW (3 times 40 amp times 400 V). I have not been able to find any further information on the kW capacity of the internal charger on three phases, however.
