Electric Vehicle Charging Time Calculator

Electric Vehicle Charging Time Calculator is a handy tool designed to help electric vehicle (EV) owners estimate the charging time for their vehicles based on their battery capacity and the type of charger used. By inputting the battery capacity in kilowatt-hours (kWh) and selecting the appropriate charger type, users can quickly obtain an estimate of the average charging time required. This calculator takes into account common charger options such as standard wall outlets (120V), Level 2 chargers (240V), and DC fast chargers.

How to Estimate Vehicle Charging Time

To estimate the charging time using the formula [charge time = battery capacity / charge power × 0.9], you can follow these steps:

  1. Determine the battery capacity of the electric vehicle in kilowatt-hours (kWh). This information can typically be found in the vehicle’s specifications or documentation.
  2. Identify the charging power in kilowatts (kW) that you plan to use to charge the vehicle. This can depend on the charging station or equipment you are using.
  3. Divide the battery capacity by the charging power to calculate the initial estimated charging time in hours. This gives you an estimate without considering any efficiency losses or factors like the current charge level.
  4. Multiply the result by 0.9 to account for efficiency losses during the charging process. This factor assumes a 90% charging efficiency, which is a common estimation.

Average Battery Charging Times

Here’s a table including the range of “Battery Capacity (kWh)” from 5 kWh to 150 kWh:
