Method: charging cost = energy ÷ 90% charging efficiency × the state's residential rate. Energy assumes 3.5 mi/kWh efficiency, a 75 kWh battery for the full-charge figure, and 12,000 miles/year. Rates: EIA, residential sector, 2024 annual average. Public DC fast charging costs more. Free to cite with a link to this page.
