Normal U.S. voltage for an appliance (such as a hair dryer) is 120 volts.  Level 1 electric vehicle charger is 120V.  Higher U.S. voltage for larger appliances (such as an electric clothes dryer) is 240 volts.  Level 2 electric vehicle charger is 240V.  Level 2 chargers will recharge a vehicle at a faster rate.

For a vehicle that can be charged at 120 volts, you can use a standard outlet with an appropriate adapter. You should consult a licensed electrician to ensure your wiring will allow you to do so.

It varies by car, manufacturer and the type of charger used. For example:

• A Level 1 charger provides charging through a standard 120V outlet. This type of charging may typically provide about 4 miles per hour of charge.
• A Level 2 charger provides charging through a standard 240V outlet. This type of charging may typically provide about 25 miles per hour of charge.

Consult the auto and/ or charger manufacturer for more information.

While charging a vehicle will be done typically overnight at home, public charging stations are becoming more and more available. Visit Afdc.energy.gov for a list of public electric vehicle charging stations. Charging levels, hours of operation and access vary by location. Contact your local officials to find out.

Before purchasing a PEV, research where you can charge it. Contact your property management.

Numerous studies have shown that a large number of PEVs could be on the grid at one time. We are incorporating the additional usage of PEVs in our electricity load forecasting.

Consult your vehicle manufacturer on the requirements for the car. The costs for charging your new vehicle will be included in your regular monthly utility bill – just like a new appliance. We will not need to do anything differently before you can enjoy your PEV.

Consult your vehicle manufacturer on the requirements for the car and a licensed electrician for questions about your home electrical outlet needs.
