Charging a 2026 Volvo EC40 at home in Tennessee

At Tennessee's residential electricity rate of 13.9¢/kWh, a 2026 Volvo EC40 (rated 31.7 kWh per 100 miles by the EPA) costs $4.4 to drive 100 miles on home charging, against $16.02 for the same distance in a car averaging 25.5 mpg on gasoline at $4.085/gallon. That works out to 72.5% cheaper per mile than gasoline in Tennessee — charging at home costs a fraction of what gas would here.

Cost of a full charge
