Assuming efficiency of ~4 miles per kWh (on the high end of current EV efficiency), that's a 200kWh battery. charging that in 10 minutes would require 1.2MW's of power, enough to power about 50-100 homes simultaneously. Now imagine a handful of vehicles charging simultaneously, consuming as much power as a small city.
That would be impractical even for fleet vehicles.
Unless they're also going to announce the development of nuclear fusion in order to provide the necessary cheap energy, then I don't think this is going anywhere.
If the discharge rate can be equally speedy, it just means any "gas pump" will include the same battery tech, load itself slowly, then unload into the car quickly. Neat way to solve the "renewables are intermittent" problem.
That's a cool idea! But then what happens when I get to the "pump" right after someone else has used it
Same thing as when you're on a regular pump and the tank is empty. Pump battery size depending on demand.
Either that or trickle charge.
