How Do Electric Cars Impact Electric Bills?

Electric vehicles (EVs) have now been on the market for several years, but many people still are left with questions about how to charge them. Specifically, there is a lot of uncertainty about how charging an electric vehicle at home will impact your electric bill. Let us help you understand EV charging and help you learn about tesla charger installation near me.

There are a few main variables to consider when calculating the cost to charge an EV. First, you need to know the electric vehicle’s predetermined range (or number of miles) that it can travel using a single charge. This is what could be “equivalent” to a gas-powered car’s tank of gas. However, with a gas-powered vehicle, it also depends on how fuel efficient the vehicle is, as well as the size/weight of a truck versus a small car. To help understand this information further, let’s explain gas-powered and electric range of miles.

Gas-powered cars are measured on miles per gallon (mpg) and the average ranges from 20-28 mpg. The median range for a gas-powered car to travel is around 413 miles, with a maximum range of 765 miles in the most fuel-efficient vehicle.

Electric vehicles on the market today can have a range of travel from 100 to just over 400 miles. The average range for an EV is 217 miles, with the highest range around 520 miles. ( So, the EPA assigns fuel economy and consumption in EV’s as X kWh/100 miles.

Next, you will need to understand what your local energy cost is at your home. You can either charge your electric vehicle at home or drive to a commercial charger location. Since you should already be aware of the cost at your local gas pump, we are now going to focus on the cost of charging your EV at your home. In addition, commercial chargers will offer different types of chargers and costs. Therefore the cost of using a commercial charger will vary in both price and length of time to charge.

Electricity cost is measured as cost per kWh (kilowatt-hour), and is a unit of energy or measurement of electrical power for one hour. To calculate the cost, find a recent copy of your electricity bill and look at the cost per kilowatt hour, or kWh. Typically, in the U.S., this cost will range from $0.09 to $0.35 kWh, depending on habits, environment, and location.

Once you know your kWh cost, then use this formula to gauge the cost to charge an electric vehicle at home:

  • Cost to Charge = (CR / RPK) x CPK
    • CR is car range
    • RPK is range per kWh
    • CPK is cost per kWh

To use this formula, divide the electric vehicle’s range in miles by its range per kWh. Then multiply it by your specific energy cost per kWh to determine how much it costs to charge an electric vehicle at your home.
