Plug-in electric vehicles

Plug-in electric vehicles (PEVs) plug into the electric grid to charge their battery packs.
Three types:

  • Battery electric vehicles (BEVs) use rechargeable batteries and electric motors for power.
  • Plug-in hybrid electric vehicles (PHEVs) are similar to BEVs but also use an internal combustion engine for power.
  • Extended range electric vehicles (EREVs) use rechargeable batteries and electric motors, and also have an internal combustion engine to recharge their batteries.

Recharging PEVs


  • Level 1 charging is supplied from a standard 120-volt outlet.
  • Level 2 charging is supplied from a 240-volt circuit, such as those supplying electric clothes dryers or other large appliances. Adding a 240-volt circuit requires an electrician and appropriate permits. Also, charging a PEV from a 240-volt circuit typically requires an in-home charging station. Check with vehicle manufacturer about recommendations for your vehicle.

Charging time depends on the vehicle, battery state-of-charge and charging rate (Level 1 vs. Level 2). Ask vehicle manufacturer about recharging times.

Public charging stations
Go to U.S. Department of Energy Alternative Fuels and Advanced Vehicles


We bill PEV charging using the same rate as your standard service. If most of your PEV charging is overnight, you may want to consider our Time-of-Use rates, which offer discounts up to 80 percent for electricity used during off-peak hours.
