Estimate real-world driving range from battery size and efficiency.
Usable energy is the battery capacity reduced to the depth of discharge you run down to. Dividing that energy by the per-mile consumption yields the driving range. Advertised ranges assume ideal conditions, so scaling by efficiency and a realistic discharge window gives a much truer everyday range.
EV Range Estimate
Range = usable battery x depth of discharge / (efficiency / 100)
Range = usable battery x depth of discharge / (efficiency / 100) Usable energy is the battery capacity reduced to the depth of discharge you run down to. Dividing that energy by the per-mile consumption yields the driving range.
Advertised ranges assume ideal conditions, so scaling by efficiency and a realistic discharge window gives a much truer everyday range.
This calculator takes 3 inputs: Usable battery, Efficiency, Usable depth of discharge. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
