Charging your EV
Charging your EV requires plugging into a charger connected to the electric grid, also called electric vehicle supply equipment (EVSE). There are three major categories of chargers, based on the amount of power the charger can provide:
AC Level 1
Provides charging through a 120 V AC plug and does not require installation of additional charging equipment. Level 1 can typically deliver two to five miles of range per hour of charging. Level 1 is most often used in home applications, but is sometimes used at workplaces. A full charge may take up to 24 hours with level-1 120 V charging.
AC Level 2
Provides charging through a 240 V plug and requires the installation of additional charging equipment by a qualified electrician/installer. Level-2 chargers typically deliver 10 to 20 miles of range per hour of charging. Level 2 is used in homes, workplaces and for some public charging. Level 2 charging systems provide slight energy efficiency benefits over level 1 chargers - savings estimates vary based on length of charge time.
DC Fast-Charge
Provides charging through 480 V AC input and requires specialized, high-powered charging equipment and special equipment in the vehicle itself. DC Fast-Charging can deliver an 80 percent battery charge or 60 to 100 miles of range for most EV models in about 20-30 minutes of charging. This format is used in public charging stations, especially along heavy-traffic corridors. Plug-in hybrid electric vehicles typically do not have fast charging capabilities.
