I agree it’s not practical, but they don’t necessarily need that output all the time. They could charge extra for faster charging and just make it so while the fast chargers aren’t being used they charge batteries/capacitors for the fast charging stalls. But even with this, the fast chargers would probably always never be available in urban areas, and this would lead to a lot of waste too if nobody is fast charging.
