As consumers increasingly adopt electric vehicles (EVs), one of the main concerns is how EV charging will affect home energy usage. After all, if you're charging your car at home, you're using a lot of electricity. But just how much of an impact do in-home EV charging stations have on your energy bill?

The Basics of In-Home Charging Stations

First, let's go over the basics of in-home charging stations. An in-home charging station (also known as an electric vehicle service equipment or EVSE) allows you to charge your EV at home. These stations are typically installed in a garage or outside your home, and they use your home's electricity to charge your car. Charging times vary based on the capacity of your station and your EV's battery, but they can take anywhere from a few hours to overnight.

In general, there are three types of charging stations:

  • Level 1: This is the slowest charging option, as it uses a standard 120-volt household outlet. Level 1 charging can take up to 24 hours or more to fully charge your EV.
  • Level 2: This is the most common type of in-home charging station, as it uses a 240-volt outlet (similar to what's used for a clothes dryer or oven). Level 2 charging can fully charge your EV in a few hours.
  • Level 3: This is the fastest type of charging station, often found outside of the home and referred to as a DC fast charger. These require a special installation due to their high voltage and can charge an EV up to 80% in just 30 minutes.

 

How In-Home Charging Stations Impact Energy Usage

Now that we have a basic understanding of what in-home charging stations are, let's dive into how they impact home energy usage. EVs use electricity, and so it makes sense that charging them at home will have an impact on your energy bill. But just how much?

According to the U.S. Department of Energy, the average EV driver uses about 2,800 kWh of energy per year for home charging. This is equivalent to about $540 in electricity costs per year for the average U.S. household, assuming an electricity rate of $0.19 per kWh.

While $540 might seem like a lot of money, it's important to keep in mind that this is still less than the average annual cost of gasoline for a conventional car, which is around $1,200. Plus, with gas prices fluctuating and EV technology improving, the gap between the two costs is likely to continue to shrink.

Advantages of In-Home Charging Stations

So, what are the advantages of installing an in-home charging station?

  • Convenience: With an in-home charging station, you can charge your EV overnight while you're sleeping, without having to worry about finding a public charging station or waiting in line.
  • Cost Savings: As mentioned earlier, home charging is typically less expensive than using public charging stations or filling up with gasoline.
  • Eco-Friendly: EVs produce zero emissions while driving, and charging them at home with renewable energy (such as solar panels) can make them even more environmentally friendly.

 

Key Takeaways

Here are a few key takeaways to keep in mind when it comes to in-home charging stations and home energy usage:

  • In-home charging stations use your home's electricity to charge your EV, so they will impact your energy bill.
  • The average U.S. household will spend around $540 per year on electricity costs for EV charging.
  • In-home charging is still less expensive than gasoline for a conventional car.
  • In-home charging is convenient, cost-effective, and eco-friendly.

 

The Bottom Line

In-home charging stations can be a game-changer for EV owners, providing a convenient, cost-effective, and eco-friendly way to charge your car at home. While they will have an impact on your energy bill, the cost savings over traditional gasoline-powered vehicles make them a worthwhile investment.
