Charging your EV requires plugging into an outlet or a charger connected to the electric grid or electric vehicle supply equipment (EVSE). There are three main types of chargers that deliver different amounts of energy based on the amount of power the charger can deliver:
Level 1 120 V Charging
With Level 1, you can charge your vehicle through a 120-volt AC plug, which does not require installation of additional charging equipment. Level 1 can typically deliver two to five miles of range per hour of charge, and a full charge may take up to 24 hours. This type of charger application is often used in homes and may be used at workplaces.
Level 2 240 V Charging
Level 2 chargers provide charging through a 240-volt AC plug and require the installation of additional extra charging equipment installed by a qualified electrician. A level 2 charging system system may also provide slight energy efficiency benefits over Level 1 chargers depending upon the length of charge time.
DC Fast-Charge
These charging systems provide power through a 480-volt AC input and require high-powered charging equipment and special equipment in the vehicle itself. This type of equipment is used in public charging stations (Plug-in hybrid electric vehicles typically do not have fast-charging capabilities).

Depending on your driving style and the distances you travel each day, you may be able to meet your driving needs with basic Level 1 charging at home. To reduce your charging time, you may want to consider installing a 240 V Level 2 system. Be sure to consult with an electrician and note that the installation of a charging system might require significant electrical upgrades to your home.
