> we could make EVs with the same form factor as today but with over a thousand miles of range. Not that we need that I think this is the way to go. For most people (you can never please everyone) 1000 miles is enough to cover a full day car trip. Then 8 hours of charge time while you sleep. Charging while you sleep requires more distributed, lower power infrastructure compared to a 10 berth service station trying to juice cars in 5 minutes as seems to be commonly touted. I haven't run the numbers but juicing 10 cars in 5 minutes has to require significant electrical infrastructure! Side bonus: never having to go to a service station. |

I believe it is becoming fairly common to use batteries as a buffer at fast chargers. The demand charges for bursting megawatts of power from the grid are apparently really steep, so it makes sense to put in a big battery and steadily draw a lower amount of power and then just charge cars from the battery.
