While having a conversation with @hornblower I realized something about charging electric cars [in the US].
Fast chargers make a profit not by selling energy, but by selling time. I can plug an electric car into any outlet. We plugged our car once into a building outlet in the middle of nowhere using an extension cord. It was fine. But it takes a Long Time, and in the current word, time is expensive. If you are pressed for time, you'll pay outrageous fees for the electricity.
