Unlike gasoline or diesel cars, EV owners can “refill” at home—just pull into your garage and plug it in using a standard outlet! All electric vehicles come with a 120-volt-compatible, or Level 1, home connector kit. It’s essentially a fancy extension cord that allows your car to be plugged into a standard outlet on one end and into the car on the other end. Level one charging is slow – typically 4 to 5 miles an hour added to your battery range. If you charge you car overnight this adds up to enough of a charge for you to leave your home the next time you drive with a full charge, especially given that most people drive 30 to 40 miles a day.
You can also install a 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.
There is a growing network of charging stations in Colorado – 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
- Will degrade battery faster than slow 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
