Calculation logicFrequently asked questions
How much does home EV charging cost?
Battery kWh times your rate divided by charger efficiency near 90 percent. A 60 kWh fill at 17 cents costs about $11.
Level 1 vs Level 2 charging?
Level 1 adds 3 to 5 miles per hour; Level 2 adds 20 to 30. Level 2 needs a 240V circuit but enables off-peak charging.
Should I charge off-peak?
Yes. TOU off-peak rates near 10 cents can halve charging cost versus daytime rates.
How do I estimate cost per mile?
Divide charging cost by miles added. EVs average 3 to 4 cents per mile; gasoline cars average 13 to 18.
