Different hardware might handle charging at different speeds. Given that I’ve personally never heard of a vehicle charging at 11 kW on a single phase, I’m all but certain the dealer was referring to the difference between single-phase and three-phase here.
A rough rule of thumb for charging losses is: 15% for single phase level 1, 10% for three-phase level 2, 5% for DCFC level 3.
It varies from car to car, obviously. But the hardware handling three-phase charging is always less lossy than the one handling single-phase.
