Supercharging V3 was just announced with one beta station, 1000 MPH of charging. Pretty incredible.
You have to think of fueling up in a different way with an EV -- you're parked at home for many hours overnight, and at work for many hours too, plug in there if you can instead of making dedicated "fuel stops" like we do in gas cars.
(I drive a plug-in hybrid)
The only way filling up my tank would take 10 minutes was if I had to queue for the pump for over 5. Also, you get much less added range from those 30 minutes with an EV, so I really doubt it's a reasonable suggestion (even if superchargers were as ubiquitous as petrol stations).
