Electric car battery range is one of the most important factors when choosing an electric car, whether it’s a new one or a used one.

The range you actually get can vary quite significantly and depends on a number of different factors, but let’s start simple, most people just want to first know what is the estimated range of a car in “standard” but realistic conditions and how to compare it between different car makes and models.

We can make things simpler with European and American electric car range standards which are for Europe NEDC which was replaced by WLTP and for America EPA.

Let’s start with NEDC, this is quite an old European standard and it is unrealistic! You would have to be driving in ideal conditions to get NEDC range, and even that is very difficult, personally my ideal real world range on Nissan Leaf 24kwh was 100 miles whereas NEDC shows 20%+ more. In practice that means it’s not useful for any comparison at all and fortunately it was replaced by WLTP.

So the real question is…

Which one is better WLTP or EPA?

The difference is that WLTP is more city-driving range and EPA is a bit more motorway driving range, which gives us an interesting choice, as you can choose just one, depending which one reflects your needs more precisely or choose both, just remembering WLTP is city-driving and EPA is with a bit more of motorway driving.

Question is, are they realistic? They are ok for standard conditions, however you have to factor in your conditions like weather, hills, driving style, battery age and for some of you may need to reduce the range by 10%, 20%, 30% or more for older batteries or extreme conditions.

Below is conversion table (estimates) between EPA, WLTP and NDEC.
