How to Use This Calculator
  1. Enter the Battery Capacity in kWh for your specific EV.
  2. Set the Efficiency rating in mi/kWh (from the EPA window sticker or vehicle display).
  3. Enter the current Temperature (°F) — cold weather significantly reduces real-world range.
  4. Review Estimated Range in miles, Adjusted Efficiency, and Usable Capacity (kWh) after accounting for conditions.
