Estimated Range vs Battery Capacity
How EV Range Is Calculated
Multiply the available battery energy by the vehicle's efficiency (miles per kWh).
Formula
Range = Battery kWh x Charge Level x Efficiency (mi/kWh)
Efficiency varies with speed, temperature, terrain, HVAC use, and driving style.
Example Calculation
75 kWh battery at 90% charge, 3.5 mi/kWh efficiency.
- 01Usable energy = 75 x 90% = 67.5 kWh
- 02Estimated range = 67.5 x 3.5 = 236 miles
- 03In kilometers = 236 x 1.609 = 380 km
