EV range estimator

range = battery kWh × efficiency (mi/kWh)

How to use EV range estimator

  1. Enter your EV's battery capacity (kWh) and its efficiency (miles per kWh).
  2. 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.
