The difference is, you can create a gas station with a barrel and a pump. No need for infrastructure.
Gas stations don't fill up themselves out of thin air — a massive infrastructure has been built (and wars fought for) for extraction, refining, and supplying the fuel.
UK's gridserve has solar farms producing 62GWh/year, that's over 2000 full recharges per day.
Their "Electric Forecourts" have 6MWh of battery storage (~100 cars).

Battery storage is common in charging stations, because it allows peak charging speeds higher than the grid connection, plus use of renewable and off-peak electricity.
