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 6 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. Visit our charging page to learn more.
  • 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 20,000 public charging stations across the country and that number is growing.* Visit our charging on the road page to learn more. 

  • All 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.
