In just 3 years? OK, there
might be a small number of EVs available with that capability by then (but I doubt it).
Have you done the math on this? How large of a battery would be needed for 600 mile range? I'd guess ~ 200 kWh (600 miles * .33 kWh/mile). To charge in 10 minutes would require a source capable of delivering 1.2 Megawatts, and a car system that can handle that current (~ 3,000 Amps at an assumed 400V). That's about 5x what the highest rated Tesla Supercharger can deliver today.
Three years strikes me as extremely optimistic. Even if it came to be, how many chargers like that will be available? Certainly not enough to count on being on your route, where and when you need it. So if that's important to you, I expect a long wait.
edit/update: So what makes you think solid state batteries will be in an EV with 600 mile range in 3 years?
These first two relevant links I found state otherwise:

So where do you get your info from?
