Here's an overview of fueling options for electric vehicles (EVs)
Level 1 Charging
Provides charging through a standard 120-volt (V) AC plug and does not require any equipment installation. All plug-in electric vehicles come with a Level 1 cord set. Level 1 charging works well for charging at home, work or anywhere a 120-V outlet is available. Depending on the vehicle and battery type, Level 1 charging adds about 5 miles of driving range per hour of charging time.
Level 2 Charging
Offers charging through a 240-V (residential) or 208-V (commercial) AC plug and requires installing charging equipment and a dedicated electrical circuit, similar to a clothes dryer or electric range. Level 2 charging is considerably faster than Level 1, making it ideal for full charging overnight at home and for recharging at work or public locations. Level 2 equipment plugs into the same connector on the vehicle as the Level 1 cord set. Depending on battery type, charger configuration and circuit capacity, Level 2 charging adds about 12 to 30 miles of range per hour of charging time.
DC Fast Charging
Enables rapid charging at specific station locations often sited along heavy traffic corridors, and at public fueling stations. At 480 volts, DC fast charging will recharge about 80% of the battery in 30 minutes. This type of charging uses a special plug compatible with many all-battery electric vehicles.
Most hydrogen fueling is available at gas stations, with dispensers placed near the gas pumps. The time required for fueling is similar to gas vehicles, typically three to seven minutes.
