Level 2 charging
Level 2 charging uses a 240 V circuit — like an electric dryer — to charge an EV at 3.3 to 19.2 kW, adding roughly 20–60 miles of range per hour. It is the standard for home charging.
A Level 2 charger is either hardwired to a dedicated circuit or plugged into a 240 V outlet such as a NEMA 14-50. Real charging speed is capped by whichever is lower: the charger output or the vehicle’s onboard AC charger.
Most EV owners install a 40–48 A Level 2 charger, which fully saturates the onboard charger of nearly every current EV.
