The supercharger cables get warm but they charge at 150 kW. Tesla has been experimenting with some supercharger liquid cooling according to googling. But 90% is not just about the cable, probably most of those 10% is lost during the chemical charging of the battery itself. And Tesla battery HVAC runs on full power when the car is being supercharged.
I do not advocate the wireless charging itself, that is a non-sense IMO.
