Electric Vehicle Driving Range Estimator
Estimate a theoretical range for a chosen usable charge window and energy consumption rate. The tool shows the method and key assumptions so you can inspect how the input values lead to the estimate.
How to use this calculator
- Enter nominal battery capacity (kwh) using the unit and definition shown beside the input.
- Enter share of capacity available for this trip (%) using the unit and definition shown beside the input.
- Enter expected consumption (kwh/100 km) using the unit and definition shown beside the input.
- Check that all values refer to the same time period and scenario.
- Review the outputs alongside the assumptions before using them in a decision.
Formula and assumptions
Estimated range=usable battery kWh/(consumption kWh per 100 km)×100 km.
- The estimate depends strongly on speed, temperature, elevation, payload, tyres, cabin heating/cooling and battery condition. Use a realistic consumption rate and leave an adequate reserve.
- The estimate is calculated from values you enter. It does not connect to external accounts, obtain live prices, or validate local regulations or engineering specifications.
Worked examples
Worked example
64 kWh with 85% usable energy and 18.5 kWh/100 km consumption gives about 294 km.
Enter the capacity, available charge percentage and expected consumption.
Do not use an estimate as a guarantee of real-world range or charging availability.
Understanding the result
The estimate depends strongly on speed, temperature, elevation, payload, tyres, cabin heating/cooling and battery condition. Use a realistic consumption rate and leave an adequate reserve.
Change one input at a time to see how sensitive the output is to that assumption.
Important notes
The estimate depends strongly on speed, temperature, elevation, payload, tyres, cabin heating/cooling and battery condition. Use a realistic consumption rate and leave an adequate reserve.
Frequently asked questions
What formula does the Electric Vehicle Driving Range Estimator use?
Estimated range=usable battery kWh/(consumption kWh per 100 km)×100 km.
What should I verify before relying on the result?
The estimate depends strongly on speed, temperature, elevation, payload, tyres, cabin heating/cooling and battery condition. Use a realistic consumption rate and leave an adequate reserve.
Can I compare different scenarios?
Yes. Change one assumption at a time, keep units and definitions consistent, and save the inputs used for each comparison.
