How to work out your EV’s real range from one journey
You do not need to run an EV from 100% to 0% to get a useful range figure. A decent-length journey and the battery percentage used are enough for a practical estimate.
Compare official range and independent estimates with what drivers actually achieve as owner journeys build — including different weather, road types and loads.
Log a real journey: miles driven, battery at the start and battery at the end. Nothing suitable to hand? On your next drive, note those three numbers and come back once you have used at least 15% battery.
One journey helps. A few good journeys in different weather, with different loads or on different roads give other drivers a much better picture. We use actual distance and displayed battery change — not the car's predicted range.

Pick the closest exact model, variant and year.
Distance, start percentage and finish percentage.
We estimate the full-battery equivalent from actual miles and displayed battery change — not the car's predicted range — and hold unusually extreme results for a quick check.

EV batteries do lose some usable capacity over time, but age, mileage and battery health are not the same thing. Here is what matters when looking at a used EV.
There is no single range number that makes an EV good or bad. The useful number depends on your longest regular journeys, charging options and how much reserve you want.
