How to use EV Range Calculator
- Enter your figures in the units shown beside each field. Keep monetary inputs in the same currency; money results are currently displayed in USD.
- Select the unit standard where the form offers a choice, then choose Calculate.
- Read the breakdown and compare the worked example below. Change one assumption to see its effect.
Formula used
Usable energy = battery capacity × usable percentage/100. Range km = usable energy ÷ consumption × 100.
Worked example
75 kWh × 90% = 67.5 kWh. At 18 kWh/100km that gives 375 km.
What the result means
If the capacity entered is already usable capacity, choose 100% to avoid deducting the buffer twice.
