The endurance of new energy electric vehicles has always been one of the most concerned places for consumers, in order to reduce the anxiety of endurance after purchasing electric vehicles, many consumers will use their mileage as a reference factor when buying related electric vehicle products. I believe that when you look at an electric vehicle product, you will find that before its production endurance, it will be specially marked with NEDC working life or CLTC working life, so what do these mean? What's different about each other? Is there anything different from our actual battery life?
In order to avoid electric vehicle manufacturers arbitrarily marking the mileage of the product, certain standards will be used when testing the endurance of electric vehicles, so whether it is NEDC or CLTC is essentially a standard used to reflect the endurance of electric vehicles in a certain state. At present, the domestic use of more is also these two standards, the following to introduce to you what is different about them.
The full name of NEDC is New European Driving Cycle, and the Chinese name is "New Standard European Cycle Test". As you can see from the name, this is a set of endurance test standards for Europe, which mainly refers to the typical road environment in Europe, including 4 urban cycles and a suburban/high-speed cycle, with a driving distance of 11km and a total time of 1180 seconds.
Although it is based on the European road environment as a reference, but it is a commonly used endurance standard, the mainland in 2003 for motor vehicle emissions testing standards have been drawing on NEDC, and then with the continuous development of electric vehicles, this set of standards began to be applied to the endurance test of electric vehicles. Until now, there are still many car companies using this standard, for example, bydir Han EV's 605km is the NEDC working mileage.
Although the name is "new", this is actually an outdated standard, and the application load such as air conditioning, headlights, and seat heating will be turned off during its test, and there will be a certain difference from the actual battery life. In this case, there are some new endurance standards, such as the CLTC endurance standard.
CLTC is a service life test standard tailored for China, which is a working condition standard defined based on 41 cities across the country, 3832 vehicle type samples, accumulated 32.78 million kilometers and 2 billion GIS traffic low-frequency dynamic big data. In general, this standard is more in line with the actual situation of mainland roads.
As we all know, the number of cars in the mainland is very large, and there are often traffic jams on the road, so the test of the CLTC working life standard is relatively more biased towards the performance of the car in the middle and low speed state, which will involve frequent acceleration and deceleration. However, there is a problem with this test standard, that is, the mileage it obtains tends to be longer than that under NEDC conditions.
The reason is that the CLTC test also turns off the application load such as turning on air conditioning, and does not reflect the various needs of the roof in the actual driving; in addition, the most important point is that because it is based on the domestic road conditions as a reference, it is inevitable that there will be a slowdown or brake, and the current electric vehicle generally has a kinetic energy recovery system, which is undoubtedly a disguised increase in the endurance of electric vehicles.
It is for this reason that many domestic car companies will choose this standard to test, it can be said that clTC working condition test to some extent is convenient for manufacturers to find the topic of marketing for publicity, although it is conducive to the promotion of new energy vehicles, but the user may form greater confusion, and even form a mileage estimate on the misleading, causing unnecessary trouble. Previously, the author introduced to you that the endurance of GAC Aean LX PLUS can reach 1008km, and it adopts the CLTC working condition endurance standard, if according to the NEDC test standard, its real endurance level may be discounted.
Write at the end:
Whether it is NEDC or CLTC, the mileage they get is ideal, and we will reduce the actual mileage in the actual car process because of the user's driving habits, etc. Of course, in any case, these endurance standards can give us a reference, we also hope that these standards can be continuously improved in the subsequent development, and the actual endurance level is closer, so that consumers can better choose.
