Plug-in electric vehicles (EVs) typically offer up to two levels of charging. The slower Level 1 is offered standard. The faster Level 2 charging is available as a premium, more expensive feature on some EV models.
Level 1 charging
120 volt, 14-16 Amps, 1.5 to 2.0 kW
This slower, lower level of charging typically requires a standard 3-prong plug with a ground-fault circuit interrupter and a commonly available grounded electrical outlet that delivers alternative current (AC). Level 1 charging consumes about the same amount of electricity as an electric hair dryer. Full recharging of the battery can require 8 to 30 hours.
Level 2 charging
240 volt, approximately 30-80 Amps, 7.5 to 19.2 kW
This faster, higher level of charging the car battery is roughly equivalent to four clothes dryers operating at the same time. This level requires a permanently wired EVSE (electric vehicle supply equipment) in a fixed location and recharges an EV in 2 to 6 hours.
You must have a qualified electrician install all EV charging equipment.
Level 3 charging options are still under development.
