Charging 101

Unlike gasoline or diesel cars, EV owners can “refill” at home—just pull into your garage and plug it in using a standard outlet! Charging is easy about about 80% of EV drivers charge at home.

You can also install a Level 2 charger in your garage or where you park your car with help from an electrician. If you need a quicker charge at home and you don’t have convenient access to a public or workplace charger, this may be the best option for you.

There is a growing network of charging stations in Colorado – with more are being added every day.

Level 1 Chargers
  • Full charge in over 12 hours
  • Typical, 3-pronged household outlet (120 V)
  • 20 amp circuit
  • Portable, mobile charger
  • Connecting charging cable that attaches to car cable typically comes with the purchase of the car
Level 2 Chargers
  • Full charge in 3-5 hours
  • Laundry room or oven outlet (240 V)
  • 40 amp circuit
  • Wall-mounted and cannot be transported
Level 3 Chargers (DC Fast Chargers)
  • Full charge in about 20-30 minutes
  • Not available for home installation (480 volts)
  • Usually located roadside or in highway corridors
  • CHAdeMO or CCS (non Tesla) chargers

Breaking down the charging cost formula
  • Level 1: $0.11/kWh (average CO cost) x 1.9 kW max capability = $0.21/hour
  • Level 2: $0.11/kWh x 6.6 kW max capability = $0.73/hour
