Electric Vehicle Basics

Plug-in electric vehicles can help increase energy security, reduce dependency on foreign oil, improve fuel economy, lower fuel costs and reduce emissions associated with operating a motor vehicle.

Charging Requirements

There are three ways to charge electric vehicles:

  • Level 1 – Uses a standard 120-volt outlet. Most plug-in electric vehicles will require 8 to 12 hours to fully charge.
  • Level 2 – Uses a 240-volt rated charging station. Charging time is typically 4 to 8 hours.
  • Level 3 – DC Quick Charge uses a 480-volt connection. Charging time is 30 to 45 minutes.

Vehicle charging equipment installation costs vary depending on the configuration of your home or business' electrical circuits, local code requirements and the type of equipment installed. The local building and safety department should be consulted to determine specific requirements. If an electrical contractor is hired to perform the work, it is the property owner’s responsibility to ensure the appropriate permits are obtained.

Before Installing a Charging Station

Contact MidAmerican Energy at 888-427-5632 if you plan to install a charging station at your home or business. A MidAmerican representative will:

  • Meet with you to determine the amount and characteristics of the load your home or business' charging equipment will add to the electric distribution system.
  • Conduct an evaluation to determine if current electric facilities need to be upgraded. If facility upgrades are needed, the property owner may be required to pay a portion of costs related to the upgrade.
  • Prepare a facility upgrade estimate, if necessary. If you approve the estimate, MidAmerican will complete any necessary facility upgrades.
  • Notify you when it is safe to operate your home or business' charging station.

Charging Your Vehicle

The best time to charge a vehicle is at night or on weekends during off-peak hours, when electricity demand and costs are lowest. MidAmerican does not offer special rates for vehicle charging; however, MidAmerican does offer optional residential time-of-use rates which may provide savings to customers who have the ability to shift significant usage, including electric vehicle charging, to nights and weekends.
