EV range calculator
Estimate how far your EV really goes between charges. Enter your usable battery size and efficiency to see a realistic range, adjusted for the conditions that affect it most.
How it works
- Multiplies usable battery capacity by your driving efficiency.
- Lets you see how weather and speed change the result.
- Gives a realistic range rather than an ideal lab figure.
What changes your result
- Outside temperature — cold can cut range 20–40%
- Speed, since aerodynamic drag rises sharply above 65 mph
- Climate control, especially cabin heating in winter
- Terrain, payload and tyre pressure
Frequently asked questions
How is real-world EV range different from the rating?
Official ratings come from controlled tests. Real range drops with cold weather, high speed, climate control and hills — often 10–30% below the sticker. This calculator estimates a realistic figure from your own efficiency.
Why does cold weather reduce EV range?
Cold lowers battery efficiency and the cabin heater draws significant power, so winter range can fall 20–40%. Preconditioning while plugged in helps by heating the battery and cabin from grid power.
How can I get more range from my EV?
Drive smoothly, keep highway speeds moderate, use eco mode and preconditioning, and keep tyres inflated. Range falls quickly above 65–70 mph because aerodynamic drag rises sharply with speed.
