Electric vehicle charging is often done at home using what is referred to as Level 1 or Level 2 charging equipment. All electric vehicles are delivered with a Level 1 charging cord that plugs into a standard 120-volt electrical outlet. For faster charging, there are Level 2 chargers that use a 240-volt electrical outlet—the same plug used by a clothes dryer. Level 2 chargers cost around $400-$800 and may require professional installation.
