BMW i4 charging questions
How much does it cost to charge a BMW i4 at home?+−
At the US average of about 16.5¢/kWh and the BMW i4’s 81 kWh usable battery, a full home charge runs about $13.41. For 1,000 miles a month that is roughly $49. Your exact cost depends on your local electricity rate.
What is the BMW i4’s charging cost per mile?+−
The BMW i4 is EPA-rated near 3.4 mi/kWh, so at 16.5¢/kWh it costs about 4.9¢ per mile to drive, compared with roughly 11¢ a mile for a 28-mpg gas car at $3.20/gallon.
How much does it cost to fast-charge a BMW i4 vs at home?+−
Public DC fast charging averages around 42¢/kWh, so a full BMW i4 charge can cost about $34, roughly three times the $13.41 it costs at home. Fine for road trips, expensive as a habit.
Do I need a Level 2 charger for a BMW i4?+−
If you drive a typical 30–40 miles a day, Level 1 barely keeps up with the BMW i4. Most owners install Level 2, see our installation cost estimator ($500–$2,500 typical).
Does winter change the BMW i4’s charging cost?+−
Yes. Expect 15–30% more energy per mile in freezing weather from cabin and battery heating, so winter months run higher than this year-round average. Preconditioning while plugged in helps.
