Level 1 is charging at home with a 120-volt circuit (i.e., using a
standard electrical outlet). This normally provides 3-5 miles of
charging per hour.
Level 2 is charging with a 240-volt circuit in the home or
workplace. This requires professional installation of either a
NEMA 14-50 outlet or a hardwired charging station, and can usually
refill your EV battery overnight.
Level 3 or Direct Current Fast Charging (DCFC) uses a 480-volt DC
circuit, and typically provides about an 80% charge in just 30
minutes. These charging stations are generally found at commercial
sites such as shopping centers or highway rest areas.
