How we calculated this

For each state we compute the home Level 2 charging cost for a Kia EV9 (99 kWh battery, 2.6 mi/kWh EPA efficiency) driving 12,000 miles per year, at the state's average residential rate. Charging losses of ~10% are accounted for.

State electricity prices come from the U.S. Energy Information Administration’s Electric Power Monthly, Table 5.6.A (April 2026). See our methodology for the full formula.
