Charging prices and charging speeds vary. Use this as a planning estimate.
Formula
range = available energy x vehicle efficiencyExample
With 50 kWh available and an efficiency of 3.5 miles per kWh, the estimated range is about 175 miles.
Assumptions and limits
- Driving speed, weather, terrain, tires, and cabin heating or cooling affect real range.
- Do not use this calculator as a trip guarantee; keep a reserve for charger availability and route conditions.
FAQ
Is this the same as EPA or WLTP range?
No. This is a simple estimate from energy and efficiency. Official range ratings use standardized test procedures.
