How it works
Energy used is the energy the car needs per 100 miles, times the distance in hundreds of miles. Multiply that by your price per kilowatt-hour to get the cost.
Home chargers, public stations and time-of-day rates all change the price. Many public stations charge by time or by session, so check the total on the app or on your bill.
Worked example
Driving 200 mi at 30 kilowatt-hours per 100 miles uses about 60 of electricity. At $0.16 per kilowatt-hour, that charge costs $9.60.
Questions
Where do I find my car's energy use?
The trip computer or app often shows kilowatt-hours per 100 miles. Your own average from recent charges is the most accurate figure.
Why is public charging more expensive?
Public stations charge for the electricity and for the time or power they supply. Compare the total in the app before you plug in.
Does this include battery loss?
If you take the energy use from your own charging records, losses are already in it. If you use a manufacturer figure, add a few percent to be realistic.
