Charging at home in Hawaii
The headline figures assume you pay Hawaii’s average residential price for every kWh. If your utility offers a time-of-use or EV plan, charging in its cheapest hours will usually beat the state average used here.
A full charge here means the energy to drive the car’s full EPA range (327 miles for the Tesla Model Y Long Range AWD), which is how the cost of a “tank” compares with gasoline. Public fast chargers set their own prices per kWh or per minute; the EV charging cost calculator lets you enter yours next to your home plan.
