Cost to run

How much does charging an EV at home cost?

Home Level 2 charging turns your driving into predictable kilowatt-hours: charger power times charging hours tracks the miles you replace. For most commuters it is far cheaper than public fast charging.

From miles to charging hours

A typical EV consumes roughly a quarter to a third of a kilowatt-hour per mile. Divide your daily miles' energy by the charger's kilowatts to get charging hours — the input these scenarios vary. Level 2 units commonly deliver seven to eleven kilowatts.

Why home charging usually wins on price

Residential rates in most states undercut public DC fast-charging prices by a wide margin, and overnight sessions harvest the car's full battery at the panel's pace. Charging losses of roughly ten percent between wall and battery are real but folded into these wall-side numbers.

Tariffs, solar, and what is excluded

This model prices the state-average flat rate; time-of-use EV tariffs, demand charges, workplace charging, and solar self-consumption can all shift the true figure substantially. Battery preconditioning in extreme weather adds draw not represented in the mileage-based scenarios.

Frequently asked questions

Is charging an EV cheaper than buying gasoline?

At state-average rates and typical efficiencies, energy per mile for home charging generally undercuts fuel per mile for comparable gas cars, though the gap varies with local prices.

Should I charge every night or run the battery low?

Electricity cost is identical either way at a flat rate — total energy tracks miles driven. Battery-health charging habits are a manufacturer-guidance question, not a cost one.

Does a more powerful home charger cost more to use?

No — it delivers the same energy in fewer hours. Higher amperage only changes speed and installation requirements, not the price of the kilowatt-hours.
