EV Range Calculator
Estimate an electric vehicle's driving range based on battery capacity, efficiency, and current charge level.
Estimated Range
236 miles
Estimated Range vs Battery Capacity
公式
## 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.
计算示例
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
常见问题
What affects EV range?
Temperature (cold reduces range 20-40%), speed (highway uses more energy), HVAC use, terrain (hills), cargo weight, and driving style all affect range.
What is typical EV efficiency?
Most EVs achieve 2.5-4.0 mi/kWh. Smaller efficient cars reach 4+ mi/kWh, while large SUVs may get 2.0-2.5 mi/kWh.
Why does my actual range differ from the EPA rating?
EPA ratings are tested under controlled conditions. Real-world range varies with temperature, speed, accessories use, and individual driving habits.
