AutoBeta(AutoBeta.net)12/13 Report--

For the majority of consumers, the endurance anxiety of new energy vehicles seems to be a topic that can never be bypassed, and many car companies will deliberately emphasize mileage when promoting new cars, taking it as a major selling point of their products. but in fact, users will suffer varying degrees of losses when using new energy vehicles, especially in the north, the gap between actual service life and official propaganda is more obvious. Recently, understanding car Emperor conducted a winter test for new energy vehicles, which has tested the performance of major brand products in the cold winter.

The test site for the winter test of new energy vehicles is also located in Yakeshi City, Hulunbuir City, Inner Mongolia Autonomous region, which is known as the "forest industry capital of China and the ice and snow capital of China". Although many new energy vehicles will also be tested in winter before coming on the market, and most of them choose to be tested in Yakeshi City, due to the large number of test projects, the problems exposed by new energy vehicle products are also very prominent. For example, the ideal L9, which can be called the "best SUV under 5 million", gets into a nest before the test is started. Before Xiaopeng G9 opened the test, the right rear door handle could not be unlocked.

Low temperature range test. According to the requirements of the test, the vehicle is fully charged, the vehicle load is 1 driver, and the air conditioner is 24 ℃ automatic mode, using economical, ECO and other power-saving driving modes. The test method is that after the vehicle is fully charged, the vehicle is left in a warm warehouse of 0 ℃ for one night, and the total mileage is recorded when the electric 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 BYD Dolphin / Seal / Yuan PLUS/ Han EV, Changan Deep Blue, BYD Seal, Xiaopeng G9, smart Elf # 1, Nezha S, Zero running C11, Tesla Model 3Universe, Polar Krypton 001, Lvlai ET5/ET7/ES7, Mengjie M5/M7, Mercedes-Benz EQE, Nissan Ariya, FAW Toyota bZ4X, etc. Of course, different mileage will also lead to differences in actual mileage, so the following models take the rate of success as the ranking criterion.

According to the Chedi test, the best flight performance is Han EV, Guanxuan mileage 610km, the actual range 366km, the rate of success is 60%. Polar Fox Alpha S and NIO ET7 ranked second and third respectively, with 58% success rate of Ultimate Fox Alpha S (500km/293km) and 55% of Ulai ET7 (675km/376km). In addition, Yuan PLUS, Xiaopeng P5, Seal, smart Elf # 1, NIO ES7 and Zero run C11 are respectively in the top 10, while dolphins, Polar Krypton 001, Zero run C01 and AION S all have a success rate of more than 50%.

The worst performers in the range test are new cars that have just hit the market, and are mainly concentrated in joint venture brands. For example, FAW Toyota bZ4X official mileage is 560km, but the actual range is only 209km, the success rate is only 37%, taking the lead to end the battery test. And Ai Ruiya from Dongfeng Nissan is also average performance, the official promotion to continue the 533km, the actual range of 250km, the rate of success is 46%. On the whole, there are still a lot of models with half mileage, such as Xiaopeng G9, Xilai ET5, Xiaopeng P7, Euler Lightning Cat, Nezha S, Model 3/Model Y, etc., with a success rate of less than 50%.

Charging test. According to the requirements of the test, the meter starts charging after the power consumption reaches 0%, turn off the electrical appliances in the car during the charging process, and uniformly use the 120kW DC charging pile. According to the car test, BYD Seal and Changan Deep Blue SL03 have the best charging performance at low temperature. both models have a charging time of 69 minutes, while Yuan plus ranks third with 76 minutes. Apart from the minicar, the worst-performing model is the FAW Toyota bZ4X, with a maximum charging power of only 42.9kW and a charging time of 423 minutes. Previously, the media have reported that the overseas Toyota bZ4X has abnormal charging problems, which will not be recharged in the cold environment, although the test vehicles do not appear to be unable to recharge, but its performance is still unflattering.

The purpose of this new climbing test is to test the torque distribution and grip of the vehicle. According to the test requirements, the maximum slope of the ice and snow ramp is 37.5 °, the driving mode with the fastest acceleration is used, the tires are replaced by snow tires of the original factory size, and the vehicle starts from the starting point and cannot continue to climb the slope to record the farthest position after full acceleration. From the test point of view, the best performance is Tang DM, the climbing distance is 34.5 m, followed by smart elf # 1, FAW Toyota bZ4X are 29.5m. The worst performer is Polar Krypton 001, which has a climbing distance of nearly 15.0m and is the only electric car with a climbing distance of less than 20.0m.

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. 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 there are many problems with the new cars that have just appeared on the market, such as the heat pump failure of Feifan R7, the failure of ideal L9 small battery, the failure of ET5 anti-lock brake, the failure of Xiaopeng G9 air suspension and so on.

In fact, most new energy models are tested in winter before they go on sale, mostly in Yakeshi. Therefore, from the understanding of the car emperor to carry out the winter test of new energy vehicles, most of the overall problems are still minor problems, such as the door can not be unlocked, air conditioning legal heat and so on. For consumers, this test still has a certain reference value, especially those in the north who intend to buy new energy vehicles but are worried about the endurance attenuation of new energy vehicles, and this winter test just covers the mainstream domestic electric products. I have a more comprehensive understanding of the endurance of electric vehicles in winter.

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.
