AutoBeta(AutoBeta.net)12/19 Report--
For the majority of consumers, the "endurance anxiety" of new energy vehicles seems to be a topic that can never be bypassed. Many car companies will deliberately emphasize mileage when promoting new cars, taking it as a major selling point of their products, but it is well known that NEDC comprehensive mileage promoted by car companies is a relatively ideal state. In fact, users will suffer losses to varying degrees when using new energy vehicles, especially in winter. The gap between the actual driving range and publicity is more obvious, and in view of the driving gap of new energy vehicles, recently, the car emperor conducted a unified test on a number of new energy vehicles, and gave the final test results.
The test site for the winter test of new energy vehicles is located in Yakeshi City, Hulunbuir City, Inner Mongolia Autonomous region, which is known as "the capital of forest industry and the capital of ice and snow in China". According to the temperature of minus 20 degrees today, it is undoubtedly a great challenge for new energy vehicles to carry out winter tests in Yakeshi.
According to the test, the battery is fully charged before the test, the driving mode is in emergency mode, the vehicle load is 1 driver + 1 passenger, and the air conditioner is in 24 ℃ automatic mode. The test method is that after the vehicle is fully charged, it starts after sitting in the garage for one night, and then completes the driving of high speed, city and comprehensive road conditions in turn. Drive smoothly during the test, and record the total mileage when the power of the vehicle is 0%.
The new energy vehicles participating in the winter test cover the mainstream models in all price ranges on the market, such as Hongguang MINIEV, Tesla Model 3/Model Y, Xilai EC6, Xiaopeng P7, Volkswagen ID.3, GAC Aion S, Polar Krypton 001, Euler Cat, BYD Dolphin, Porsche Taycan and so on. Of course, different mileage will also lead to differences in actual mileage, so the following car rankings are for reference only.
The top 10 models with measured mileage at low temperature are Xilai EC6, Xiaopeng P7, Polar Krypton 001, Nezhu U, Gaohe HiPhi X, Guangzhou Automobile Aion Y, Tesla Model Y, Geely Geometry C, Audi e-tron and Volkswagen ID.4X. From the above ranking, it is not difficult to see that the advantages of domestic independent models are slightly larger, and 7 of the 10 models are from Chinese car companies. However, even if the above models have some advantages, they are roughly halved compared with the official mileage due to the harsh environment of minus 15-20 ℃. For example, the official mileage of the EC6 is 615km, and the measured range is 336.9km. The official mileage is 670km Xiaopeng P7, and the measured range is 316.2km. The official mileage is 606km's polar krypton 001, and the actual range is 298.4km.
The same is true for models other than the top ten, with mileage basically halved, and some models have some conditions under such extremely cold conditions. For example, the 12th Zero C11, the official mileage is 610km, the actual mileage is 260.5km, the sudden situation is in extremely cold conditions, the vehicle suddenly lost power, unable to drive. MARVEL R, which ranks 18th, has an official mileage of 505km and an actual range of 231.6km, resulting in an abnormal power loss during the test, resulting in the vehicle being unable to drive. The most serious is the bottom-ranked horse herder 4xe, whose official mileage is 55km, but its mileage is 0 because pure electric mode cannot be used at low temperatures.
If you put aside the mileage ranking and compare the official mileage with the actual mileage, in fact, the best performance is Hongguang MINIEV. It is understood that the test is the 2022 Macaron perfect version, the official mileage is 170km, the actual mileage is 103.2km, and the rate of success is 60.71%. Audi e-tron is officially continued for 465km, the actual range is 272.3km, with a success rate of 58.56%. The official mileage of Baojun KIWI EV is 305km, and the actual mileage is 172.4km, with a success rate of 56.52%.
In fact, judging from the rankings published above, most of them can sum up two major rules. One is that the endurance performance of domestic new energy vehicles is better than that of joint venture / imported models. However, it should be noted that the actual endurance performance of domestic new energy vehicles is better, mainly because more domestic vehicles are involved in the battery life, and only 11 of the 40 models are joint ventures / imports. Of course, this situation also reflects that the domestic development of domestic new energy vehicles is indeed better than that of joint venture / imported new energy vehicles.
The second is that the new energy models with lower prices have a higher rate of success, that is, the actual range loss is less than the official range, such as Hongguang MINIEV, Baojun KIWIEV, BYD dolphin and so on.
In addition to testing the endurance attenuation, the car understanding emperor also carried out a low-temperature charging test for the above models, mainly to examine the charging ability of new energy vehicles in extremely cold environments. The test standard is that the electricity of the new energy vehicle is 30% before the test, the test state is cold car, and the third-party charging pile (charging power 120kw) is used. The test rule is that the time starts when 30% of the electricity is displayed, does not rush into 5% of the electricity, and records a charging event and the change of charging power until the charge reaches 80%.
Judging from the published list, the higher the basic price, the shorter the charging time of new energy models. For example, the price range of the Red Flag E-HS9 is 50.98-779800 yuan, the low temperature charging event is 32 minutes, the Porsche Taycan and Tesla Model Y are 37 minutes, and the polar krypton 001 is 38 minutes. However, charging in this extremely cold environment, the performance of domestic electric cars is not satisfactory, such as ES8, EC6, GAC Aion V, Ola good cat, Nezhu U, Euler black cat. Nezhu V, Baojun KIWIEV charging market are more than 60 minutes (including 60 minutes), especially Nezhu V and Baojun KIWIEV charging abnormal, can not charge normally fast.
Understanding the car emperor to carry out the winter test of new energy vehicles, there is still a certain reference value for consumers who intend to buy electric vehicles, especially those in the north who intend to buy new energy vehicles but are worried about the endurance attenuation of new energy vehicles. This winter test just covers the domestic mainstream electric products, and has a more comprehensive understanding of the winter driving of electric vehicles. Of course, the location of the test is Yakeshi, and the environment of minus 15-20 ℃ is indeed harsh for electric vehicles, which can be said to challenge the performance of new energy vehicles in all aspects to the maximum, while the current temperature in the northern part of the country is generally above minus 10 ℃. Therefore, although the battery life of the electric car tested is basically halved, it can reach the maximum, and the performance of northern users will be better than that of the test.
