For the majority of consumers, new energy vehicle "endurance anxiety" seems to be a topic that can never be avoided, many car companies will deliberately emphasize the mileage when promoting new cars, taking it as a major selling point of the product, but as we all know that the NEDC comprehensive mileage promoted by car companies is a relatively ideal state, in fact, users will have different degrees of losses when using new energy vehicles, especially in winter, the gap between actual endurance and publicity is more obvious, and the endurance gap for new energy vehicles. Recently, Chedi has conducted a unified test on a variety of new energy vehicles and given the final test results.
Understand the car emperor for the new energy vehicle winter test test site is located in the Inner Mongolia Autonomous Region Hulunbuir City Yakeshi City, the region is the northern part of the Inner Mongolia Autonomous Region, known as "China's forest industry capital, China's ice and snow capital", according to today's temperature of minus 20 degrees, understand the car emperor in Yakeshi winter test for new energy vehicles is undoubtedly a great challenge.
According to the test to go, the power before the test is fully charged, the driving mode adopts emergency mode, the vehicle loads 1 driver + one passenger, and the air conditioning is 24 ° C automatic mode. The test method is that after the vehicle is fully charged, it will be left in the garage overnight, and then complete the high-speed, urban and comprehensive road conditions. Drive smoothly during the test and record the total mileage when the vehicle is 0% charged.
The new energy vehicles participating in the winter test cover the mainstream models of various price ranges in the market, such as Hongguang MINIEV, Tesla Model 3/Model Y, NIO EC6, Xiaopeng P7, Volkswagen ID.3, GAC Aion S, Extreme Kr 001, Euler Good Cat, BYD Dolphin, Porsche Taycan and other models. Of course, different mileage will also lead to differences in actual endurance, so the following model rankings are for reference only.
The top ten models with low-temperature measured mileage are WEILAI EC6, Xiaopeng P7, Extreme Krypton 001, Nezha U, Gaohe HiPhi X, GAC 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 certain advantages in performance, due to the harsh environment of minus 15-20 ° C, these models are basically waist-cut compared to the official advertised mileage. For example, the WEILAI EC6, which has an official cruising range of 615km, has a measured cruising range of 336.9km. The official mileage is 670km of Xiaopeng P7, and the measured mileage is 316.2km. The official mileage is 606km of the Extreme Krypton 001, and the actual cruising range is 298.4km.
The same is true for models outside the top ten, with the mileage basically showing a waist cut, and some models have some conditions in this extremely cold condition. For example, the 12th zero-run C11, the official mileage is 610km, the actual endurance is 260.5km, the sudden situation is in the extremely cold conditions, the vehicle suddenly loses power and can not drive. The 18th ranked MARVEL R, with an official cruising range of 505km and an actual range of 231.6km, experienced an abnormal power loss during the test, resulting in the vehicle being unable to drive. The most serious is the bottom-ranked Wrangler 4xe, with an official range of 55km, but its range is 0 due to the inability to use pure electric mode in low temperatures.
If you put aside the mileage ranking and compare it with the actual battery life according to the official endurance, the best performer is actually the Hongguang MINIEV. It is understood that the participation in the test is the 2022 macaron perfect version, the official mileage is 170km, the actual mileage is 103.2km, and the mileage achievement rate is 60.71%. The official endurance of the Audi e-tron is 465km, the actual endurance is 272.3km, and the endurance achievement rate is 58.56%. The official mileage of Baojun KIWI EV is 305km, the actual cruising range is 172.4km, and the endurance achievement rate is 56.52%.
In fact, from the above published rankings, most of them can summarize two major laws. One is that the battery life 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 the models involved in the endurance are more domestic cars, and only 11 of the 40 models are joint ventures/imports. Of course, this situation also reflects from the side that the current development of domestic new energy vehicles in China is indeed better than that of joint ventures/imported new energy models.
The second is that the endurance rate of new energy models with lower prices is higher, that is, the actual endurance is less than the official endurance loss, such as Hongguang MINIEV, Baojun KIWIEV, BYD Dolphin and so on.
In addition to testing endurance attenuation, Chedi also conducted a low-temperature charging test for the above models, mainly to investigate the charging capacity of new energy vehicles in extremely cold environments. The test standard is that the power of the new energy vehicle before the test is 30%, the test state is cold, and the third-party charging pile (charging power is 120kw). The test rule is that the timer starts from 30% of the meter power, does not rush into 5% of the power, and records the first charge event and the change of charging power until the power reaches 80%.
Judging from the list released, the higher the base price, the shorter the charging time of new energy models. For example, the Hongqi E-HS9, which is priced in the range of 50.98-779,800 yuan, has a low-temperature charging event of 32 minutes, the Porsche Taycan and Tesla Model Y are 37 minutes, and the Extreme Kr 001 is 38 minutes. However, charging in this extremely cold environment, the performance of domestic electric vehicles is not ideal, such as Weilai ES8, Weilai EC6, GAC Aion V, Euler Good Cat, Nezha U, Euler Black Cat. Nezha V and Baojun KIWIEV charging market are more than 60 minutes (including 60 minutes), especially Nezha V and Baojun KIWIEV have abnormal charging and cannot be charged normally and fast.
Understand the car emperor this time on the new energy vehicle winter test, for consumers who intend to buy electric vehicles still have a certain reference value, especially in the north of the consumers, interested in buying new energy vehicles but there are concerns about the endurance of new energy vehicles, and this winter test just covers the domestic mainstream electric products, for electric vehicles winter endurance has a more comprehensive understanding. Of course, the location of the test is Yakeshi, and the environment of minus 15-20 °C is indeed more demanding for electric vehicles, which can be said to be the greatest challenge to the performance of all aspects of new energy vehicles, and the current temperature in the northerner regions of China is generally above minus 10 °C. Therefore, although the endurance of the tested electric vehicle is basically waist chopped, it can reach the maximum, and the northern users will have better results than the test in actual use.
