Charging at Home

Charging your electric vehicle (EV) at home is inexpensive and convenient. You’ll be able to charge at the standard residential electric rate, which varies but is typically less than fuel costs.

Types of Chargers

There are two types of residential EV chargers on the market. Depending on your car model, you’ll need to decide which charger works for your car and your lifestyle. 

Basic Charger Types Range Charged Per Hour Ideal Use Connectors
Level 1: Standard 120-volt wall outlet Up to 6 miles of range per hour Overnight charging for average daily driving

A good option for plug-in hybrids because of their smaller batteries
J1772: Compatible with all cars (Tesla® provides an adapter). Charging cable and connector usually included with the EV
Level 2: 240-volt outlet similar to a clothes dryer outlet Usually around 25 miles of range per hour but can go as high as 60 miles of range per hour depending on the car and equipment Quick charging at home or at work. Can be used for overnight charging.
J1772: Compatible with all cars (Tesla provides an adapter). Charging cable and connector sometimes included with the EV


It’s easy and convenient to charge your EV overnight while you sleep. It will be ready to go for the day when you wake. To get started, follow these steps:

Best Time to Charge

Driving an EV is better for the environment – your car produces zero emissions. To further help the planet and the grid, be sure to charge your EV overnight. This is generally when everyone is using less energy and the grid is not working as hard to supply power. Thanks for doing your part.

Frequently Asked Questions

  • Most EVs can charge on a standard 120-volt outlet, so you may be able to use an existing outlet. The charge from this outlet is relatively slow, up to 5 miles per hour, so you may consider installing a 240-volt Level 2 charging station, which can charge your vehicle up to six times faster. Read more above about the steps for installing an EV charger.
  • It all depends on the type of vehicle you own, your driving habits, how much energy is stored in the battery and what type of charging system you have in place. Use our chart above to see how long each charger takes.
  • The cost of charging EVs depends on the size of the battery and how much electricity you use. For customers who drive less than 40 miles a day, at 11 cents per kilowatt-hour (the national average), it should cost less than $1 to $1.50 a day to fuel an EV. Your electric bill will likely go up, but your monthly gasoline expenses should drop considerably more.
  • Very likely, yes. There are more than 8,000 public charging stations across the country and that number is growing. Visit the Plugshare map on our website to find a station. 
  • All plug-in EVs and associated batteries are tested by the National Highway Traffic Safety Administration (NHTSA) under extreme operating conditions to achieve the same high safety standards as conventional vehicles.
