I guess it varies. The ones around here that are not free are usually $0.35/kWh, with a $2 minimum. The city will be converting one free one to $16/hr. (L2 here are almost all free at the moment.)
But at $0.15/minute—the price charged at a couple of stations in Goleta—that would be $4.50 to bring an empty tank to 80%, or about 92 miles. A 35 mpg car would require 2.63 gallons of fuel to go that far, which would be $8.04 at California's current average of $3.059/gal.
Yeah the DC fast chargers are a gamble. Royal Farms at $0.29/kwh, minimum charge $3.50 (12kwh) is close, at (assuming 4 mi/kwh) $0.0725/mile ... at $2.30/gal regular gas (MD) that would be the cost/mile for a 31mpg car. As gas prices rise, the economics get a little better.
EVgo around here with a basic account does $5.95 connection charge plus $0.20/minute I think. So for 20 minutes I could expect to charge around 14kwh or so, that'd be a cost-per-mile of $0.177 or (at gas prices 2.30) equivalent of a car making 13mpg.
Economics get a tad better if you let an EVgo station run for 30 minutes, but probably not much better since the charge rate tapers off.
Then there's the DC fast charger I had the treat to use this morning - Baltimore's Enoch Pratt Free Library level 3 charger by Roland Ave, installed by the "EV Institute" (who is putting L2 and some L3's in all the EPFL libraries), doing 330V/100A (33kW) Level 3 charging for *free*!
