The weight and aerodynamics of a vehicle has tremendous impact on efficiency.The fact that colder air results in more aerodynamic drag might also play a role. The main reason is probably the energy needed to heat the battery combined with the electronics preserving the battery with larger offset from total discharge. The curve seems to flatten at high temperatures, but seems to decline steeper the colder it gets. The temperatures impact on effective range is interesting due to that fact that it is not linear.The NEDC ratio between LEAF vs e-NV200 is 1 to 1.2, while the tested ratio is 1 to 1.4 at 20☌ and 1.3 at 0☌. ![]() The real world range is way lower than NEDC claims. This test shows very clearly how useless the NEDC norm is. If you look closely you might wonder if the two cars will have equally poor range at -10☌ and below. The LEAF was more sensitive to temperature change than the e-NV200, and that is probably due to it being a lot lighter and having better aerodynamics than the e-NV200, thus making the temperature account for more in total resistance. Look at those curves: the LEAF had up to 50% longer range! ![]() The summer I had the e-NV200 I never had the opportunity to measure the range in temperatures above 20☌ so it might have been able to get more than 100 km (62 miles). That trip gave me a very thorough feel of what this car could do. One of the first things I did with the e-NV200 though was to go on an insane long-distance trip with my family that claimed a total of eight charge stops. A friend of mine had leased the exact same car at the same time, even doing the same commute, and he learned the hard way by running out of electrons on the highway 10 miles from home. I had not realized how optimistic the European NEDC standard was. When I started out with the e-NV200, I honestly thought something was wrong with it. I always used air conditioning and did not bother much with ECO-mode since it did not make that much of a difference anyway. Each car traveled a total of 25,000 km (15,000 miles) including the occasional weekend or vacation trip. The last third is in dense stop & go traffic in the city. Another third is highway at speeds around 110 km/h (70 mph). One third is countryside road at stable speeds around 80 km/h (50 mph). My commute is 30 km (19 miles) in each direction in a mixture of roadways. ![]() Wheels: Alloy rims with 205/55 R 16 tires Wheels: Alloy rims with 185/65 R 15 tires How does the build of a car affect the range?.How does the temperature affect the range?.This meant that I could get answers to these two questions: Which was especially interesting due to the fact that they share the exact same battery and drivetrain. I was lucky enough to lease the Nissan e-NV200 for one year and then the Nissan LEAF the next year, in exactly the same conditions. And if you live in a part of the world where winter actually means frost and snow, you will definitely realize just how your EV’s range is affected when the cold kicks in.īut how much exactly does that cold affect the range of an EV? It takes a lot of measurements at different temperatures to get a clear impression. When you decide to base your daily commute on an EV, the word range becomes the most used in your vocabulary.
