How far can I travel on a full battery charge?

The distance you can travel on a full charge will vary based on the vehicle type, battery size and age, and other factors, such as topography and driving habits. 
In general, though, the Nissan Leaf is expected to be able to travel about 100 miles on a full charge. Drivers of the Chevy Volt, which operates on both electricity and gasoline, should be able to travel for about 40 miles before the vehicle starts using gasoline.

Can I charge my electric vehicle at home?

Yes, you can charge your vehicle at home. The new generation of electric vehicles will have standardized connectors to charge as either Level 1 (120-volt) or Level 2 (240 volt).

How much will it cost to charge an EV?

The cost for charging will depend on the vehicle's battery size. The Nissan Leaf now comes equipped with a 24 or 30-kilowatt-hour battery. So, if you charge your vehicle from a 50-percent charge to 100 percent (about 12-kilowatt-hours), it would cost a little more than a dollar with residential rates at about 10 cents per kilowatt-hour.

How long will it take to charge my vehicle?

That will depend on your vehicle's battery size and whether you are using Level 1 or Level 2 charging. As an example, the Nissan Leaf is expected to take 18 to 24 hours to charge with Level 1 and 4 to 8 hours with Level 2 according to Nissan.

How do I prepare my home for electric vehicle supply equipment?

Much like adding a pool or hot tub at your home, there will be considerations you will need to make regarding the electric service at your house. You need to work with your vehicle dealer. The electrician will need to purchase a State Electrical Permit and arrange for an inspection by the state. Depending on the age of your home, you may require service panel upgrades. Level 2 charging equipment will require a 240-volt, 40-amp dedicated circuit connected to a breaker. It will need to be hard-wired directly to the circuit by a licensed electrician. You should also contact MTEMC to determine if any MTEMC system upgrades will be needed.

What are the different charging levels?


  • Level 1: 
    • Charges at 120 volts, the same voltage as a standard home electric outlet. Level 1 would be like running a hair dryer for the amount of time it takes to charge your vehicle. 
  • Level 2: 
    • Charges at 240 volts, the same voltage as a clothes dryer outlet. Vehicles charging with a Level 2 system would use about as much energy as running both a handheld hair dryer and clothes dryer for the time it takes to charge your vehicle. 
  • DC Fast Charge: 
    • Requires 3 phase power. There will be 60 fast-charge locations installed in Tennessee around Knoxville, Nashville and Chattanooga.
