Financial aspects of Using EV charging stations

Monetary Perspective: EV Charging versus Gasoline Fueling

When comparing the operating cost of electric vehicles (EVs) to that of their gasoline-powered counterparts, EVs tend to be significantly cheaper per mile. Based on data from the U.S. Department of Energy’s eGallon tool, operating an EV costs about half the expense of a typical gasoline-fueled car. This substantial operational cost advantage compensates for the steeper initial costs of buying an electric vehicle, making them an attractive option for many consumers.

Determining EV Charging Costs

The cost of charging an electric vehicle can vary widely, depending on a number of factors. Firstly, the cost of electricity significantly influences EV charging costs. Essentially, charging an electric vehicle is like filling up a gas tank—but instead of using gallons of gas, you’re using kilowatt-hours (kWh) of electricity. The average cost per kWh in the U.S is around 13 cents. This means, for a car with a 60 kWh battery and a range of 200 miles, a full charge could cost around $7.80 and will cover those 200 miles. However, this price fluctuates based on the region’s electricity rates.

Another factor is the power rating of the charger. Level 1 charging cords, which can be plugged into a regular residential outlet, deliver 2-5 miles of range per hour of charging.
