Hello. Still doing my reseach to see if a Model S is the right car for me. One of the businesses I own has a pretty heavy-duty electric supply. Commercial-service 3 phase 480v with a 600 amp panel. This business is 200 miles way from my house. So for the times when I drive there, it would be great if I could plug in the car and charge it rather rapidly for my drive back home. Could I possibly install a high-current charger at this business for a MS? Tesla Superchargers probably have some proprietary technology in them that I couldn't get, but with that kind of elec supply, what is highest charging capacity I could do? Any elec engineers in here?
