Fuel Fact of the Week

Fact #1149: The Cost of Charging an Electric Vehicle in the United States Averages 15 Cents per Kilowatt-Hour

The cost of charging electric vehicles varies depending on multiple factors, including electricity price, charging equipment type, installation cost, and number of miles driven. The National Renewable Energy Laboratory and Idaho National Laboratory studied data on all-electric vehicle (EV) use and charging to determine a weighted average cost of charging an EV. They found that the national average EV charging cost ranges from eight cents per kilowatt-hour (kWh) to 27 cents per kWh, with an average of 15 cents per kWh. Based on current charging behavior patterns, the average assumes that 81% of charging was at home, 14% at the workplace or public station, and 5% with a DC fast charger. This translates to an average vehicle lifetime fuel cost savings of $3,000 to $10,500, offsetting or exceeding the higher upfront cost of EVs.

Question of the Month

How is fuel economy determined and reported for alternative fuel vehicles?

Last month we learned about how the U.S. Environmental Protection Agency (EPA) determines and reports conventional light-duty vehicle fuel economy ratings. While alternative fuel vehicle (AFV) fuel economy testing is largely similar to that of conventional fuels, the EPA makes some adjustments to account for different vehicle technology and fuel energy content. By tailoring AFV fuel economy testing and reporting, the EPA is able to provide apples-to-apples comparisons and allow consumers to make informed decisions.
