For a smaller EV It would take around 200kWh worth of battery for a 600 mile range. The current Tesla "superchargers" put out 250kWh. So whatever is going to charge this battery will have to output roughly an order of magnitude more power in order to charge the battery in 6 minutes. That's an impressive and scary amount of energy transfer.
Edit: I don't know where I got 6 minutes from. So not quite 10X the power for charging, but a LOT more than current chargers.
This is the big reason why solid state batteries aren't an EV miracle. Pack density and charging speeds these days are already limited by cooling capacity. Trying to pump a few MW of power into a battery pack to get 600 miles in 9 minutes is going to melt the car, or require lugging around a huge cooling system.
Standardized interchangeable batteries would be neat. Pull into a battery station, a machine swaps out your packs and you're on your way faster than a fill-up.
That was one of the original tesla quick"charge" concepts. You'd drive over a pit like oil stops and it situs swap out your battery for a charged one
