DC fast chargers tend to cost much more than level 2 chargers. They have expensive equipment, more expensive electricity (intermittent high load is more expensive than more continuous lower levels, even for the same total power), and there tends to be a limited number of them so you want to encourage people to do level 2 charging when possible, and only DC fast charging on road trips when they really need it. So prices are much higher than for normal AC charging. Most of the charging you do should be AC charging at your home or work.
