EV Charging Time Calculator
Pick your car and your charger; work out the estimated charging time and the cost per kilometre from the battery capacity, the car's onboard AC charging power and the current step you select. Charging speed is set not by the unit but by whichever is lower (the car's onboard charger or your installation), and the calculator accounts for that limit.
