EV range estimator
range = battery kWh × efficiency (mi/kWh)
How to use EV range estimator
- Enter your EV's battery capacity (kWh) and its efficiency (miles per kWh).
- Estimated range calculates as battery kWh × efficiency.
Limitations
- Real-world range varies with driving speed, temperature, terrain, and battery age — this gives a baseline estimate, not a guaranteed number for a specific trip.
