These numbers are based on the usage reported by a "pay per kWh" Level 2 charging station at one of my sites.
Started at "0%" and charged to full. Car is only a few weeks old, so it's still "learning", perhaps?
It took 3.25kW for 2.5 hours, not counting that taper off in the last few minutes:
Total power "delivered" was 7.01kWh. According to MyFord Mobile, capacity used on the way home (again, went back to "0%" before switching to hybrid mode) was 5.5kWh, so that yields only a 78% charging efficiency. Worse than expected. The parking garage was about 10°F warmer than outside (32°F per the picture), and the cooling fans were running while charging.
The rate per kWh was ridiculous for this area, but I wanted to give it a shot.
At home, Dominion VA Power charges:
So my Level 2 charger at home costs me $.67 per "fill up" from "0%" to "100%". I go between 15 and 17 miles per charge due to the hilly terrain even with a 98-99% regenerative braking score, meaning the car costs me $0.044 / mile to operate.
Edit: I installed the L2 charger myself, so it cost me the price of the charger ($470), the cost of 50' of 6/3 wire ($150), a 220V 40A breaker ($5), and some conduit ($2). I've never used the 110V charger.
