Why a “full charge” is the wrong number to budget with
Few drivers charge from empty to full, so the number that shapes your bill is energy per mile: 31.1 kWh per 100 miles for the Chevrolet Equinox EV FWD. EPA measures it at the wall outlet on Level 2 charging, so the energy lost in the charger is already included. The average US car covers about 11,040 miles a year (FHWA), which for this model is about 3,433 kWh.
Cold weather raises consumption. In testing cited by fueleconomy.gov (a AAA study), EV efficiency at 20°F was about 39% lower with the cabin heater on, and 8% lower with it off.
Your tariff matters as much as the car: on a time-of-use EV plan the overnight price can be a fraction of the evening peak. Put your utility and charging hour into the EV charging cost calculator for your real number.
