In my city (Bellevue, WA), there's ChargePoint stations operated by the city in free street parking and in the park, so the cost is entirely in the operation of the EV station and electricity. It might not seem bad, but it isn't necessarily competitive with a Supercharger or home charging in terms of cost. Blink is worse, at 39c-49c per kWh, which is about $2.50 per hour at the low end.
