Fast chargers known as Level 3 — nearly 20 times faster — can top off an EV battery to about 80 percent in as little as 20 minutes. But that typically costs 30 to 48 cents per kWh — a price equivalent to gasoline in some places, as I later found out.

I failed to specify fast/superchargers. Some have reported higher rates to charge than the gas equivalent range using commercial fast chargers.
