The physical station the EV would hook up to is 5% of the system required.
There must be power lines installed from the high voltage street feeder.
There has to be adequate current on the street feed. Usually run higher power transmission lines from power source to the load.
There has to be adequate power generation plants available to deliver that street feed 24/7/365 not dependent on Sun or wind, which is the very most inconsistent power deliver humanly possible.
The charging power for the speedy chargers is 360,000 W
About 10X what my house is wired for (any my house is wired above average of US houses) and we normally use about tenth of it.
If you have, say, five or six charging stations, you need wiring for good 500 houses. Basically for a town of couple thousands of residents. That’s hard to do.
So many, (most) charging stations are very slow, using less power.
At my home, using 120V charger, EV would take few days to fully charge.
