Types of Chargers

When you purchase an electric car, you will receive a portable, weatherproof charging cable to connect your car to an electric outlet or charging station. All EVs can plug into standard household outlets:

“Level 1” Charging

  • Plugs into a standard household outlet (120 volt)
  • Fully charges battery in 10 to 20 hours, adding 2 to 5 miles of range per hour
  • No additional cost or installation required
  • Best suited for drivers with regular schedules and/or short commutes

“Level 2” Charging

  • Plugs into an outlet like that of a clothes dryer or other major household appliance (240 volt)
  • Fully charges battery in 4 to 6 hours, adding 10 to 20 miles of range per hour
  • Requires installation by a certified electrician
  • Typically costs $1,500 to $2,000 for charger and installation; Illinois residents are eligible for a rebate of up to 50% of installation charges.
  • Best suited for drivers with irregular schedules and/or longer commutes

“Level 3” Charging

  • Also known as Direct-Current (DC) or Fast Charging
  • Recharges some batteries in less than 30 minutes — by far the most powerful charging method (480 volts)
  • Best suited for public charging stations, as cost is prohibitive for residential use

Tesla’s Exclusive “Supercharger” Network

  • Works exclusively with the Tesla Model S
  • Allows owners to charge for free
  • Located along well-traveled highways in North America
  • Provides half a charge in about 20 minutes

When considering what type of charging to use at home, you should consider the distance of your commute, regularity of your schedule, and cost of installation to determine which charging option is best for you.
