When to use this calculator
This is an energy-budget estimate for the selected conditions, rather than a certified vehicle range.

PUTTING IT INTO PRACTICE
EV Range: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| Usable battery energy (kWh) | 60 |
| Consumption (kWh/100 km) | 20 |
| Result | 300 km |
- Check the input labels and enter the example values above.
- Apply the relationship: Range = usable battery energy/consumption × 100.
- The result is 300 km, rounded for display.
How to interpret your result
Use usable energy after any reserve. Speed, weather, heating and degradation can change actual range.
Usable battery capacity differs from gross rated capacity. Charging losses mean grid energy can exceed energy added to the battery. Constant-power time estimates do not reproduce a full charging curve.
Frequently asked questions
Will a constant-power charging estimate match a real session?
Not necessarily. Actual power can taper or vary with temperature, state of charge, equipment and power sharing.
When is the ev range calculator useful?
This is an energy-budget estimate for the selected conditions, rather than a certified vehicle range.
How do I use the ev range calculator?
Enter usable battery energy (kwh), consumption (kwh/100 km). The result updates automatically. Use the units shown beside each input; the example values illustrate the method.
Which formula does this calculator use?
Range = usable battery energy/consumption × 100.
What should I check before using the result?
Use usable energy after any reserve. Speed, weather, heating and degradation can change actual range.
How are results rounded?
Scalar numbers display up to six decimal places, with scientific notation for very large or small values. Text, fraction, date and schedule outputs use the format described on the tool. Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
