EV Charging Time Calculator

Estimate EV charging time by battery size, starting percentage, target percentage, charger power, and charging efficiency.

Use this tool to estimate how long a charge session may take. It is most useful for comparing Level 1, Level 2, wall connector, and DC fast-charging scenarios.

Why Charging Time Is Only an Estimate

Actual charging speed depends on battery temperature, state of charge, charger output, vehicle limits, voltage, weather, and whether the car tapers charging power near the top of the battery. Level 2 estimates are usually easier to predict than DC fast charging.
