EV & E-Bike Range Calculator
Estimate real-world range for an electric car or e-bike from battery size and consumption, adjusted for temperature, speed and heating or AC.
How to use
- 1Enter the usable battery capacity and typical consumption.
- 2Choose the conditions: temperature, driving style and whether you're using the heater.
How it's calculated
Range = usable battery (kWh or Wh) ÷ consumption × condition factor. Cold weather (below 0 °C) with heating commonly cuts EV range by 20–40%.
Frequently asked questions
Why does range drop in winter?
Batteries are less efficient when cold, and cabin heating uses a lot of energy — heat pumps help considerably.
Does highway driving reduce range?
Yes — aerodynamic drag rises steeply with speed, so 75 mph (120 km/h) can use 20–30% more energy than 55 mph (90 km/h).
What consumption do e-bikes have?
Typically 10–20 Wh per km depending on assist level, rider weight, hills and wind.
