On December 14, ByteDance's automotive media Dongchedi held a winter test open day in Mohe, inviting a total of 25 groups of car companies, media, industry organizations, user representatives, etc. to observe and broadcast the whole process live, in order to "respond" to the questions of various car companies.
It is worth noting that with the advent of the cold wave and blizzard, many new energy vehicle owners have begun to complain about battery life, which is more obvious in the north, low temperature will lead to faster discharge rate of the battery, and the storage capacity of the battery will also be greatly reduced.
Some industry insiders pointed out that from the actual situation of new energy vehicle batteries at this stage, the Northeast Alpine region is not suitable for the large-scale promotion of the use of pure electric new energy vehicles.
Looking up to the U8, once again won the first place in the endurance test
Two models failed the "Split Road Elk Test"
The reporter of "Daily Economic News" learned through the live broadcast that two tests were carried out in the morning and afternoon on the open day of the winter test of Chedi, and the test content was "extended range/plug-in hybrid pure electric endurance test" and "open road elk test". Among them, the "extended-range/plug-in hybrid pure electric range test officially started at around 9:25, and a total of six models participated in the test.
According to the live broadcast content, in the "extended range/plug-in hybrid pure electric range test", the first model to withdraw is the Lynk & Co 08EM-P, with a pure electric mileage of about 6.5 kilometers, the second model to withdraw is the new M7, when the remaining power of the power battery is 31%, the engine intervenes, and the actual pure electric range is 10.6 kilometers, and the third model to withdraw from the test is the Wei brand Gaoshan DHT, with a pure electric range of about 17.4 kilometers, and the engine has a remaining power of 29% The fourth model to exit the test is the Denza D9, with an engine with an all-electric range of 18.9 km when the remaining charge is 24%, the fifth model to exit is the VOYAH FREE, with a pure electric range of 36.8 km, and the last model to exit the test is the Yangwang U8, with an all-electric range of 65.5 km, and the engine intervenes when the remaining charge is 23%.
According to public information, the pure electric range of the Lynk & Co 08 is 185 kilometers, the official nominal pure electric range of the new M7 is 175 kilometers, the pure electric range of the Wei brand Gaoshan DHT is 140 kilometers, and the pure electric range of the Denza D9, VOYAH FREE, and Yangwang U8 is 145 kilometers, 160 kilometers, and 124 kilometers respectively. In this test, the pure electric range achievement rates were 3.5%, 6%, 12.4%, 13%, 23% and 52.8%, respectively.
In the previous "2023 Chedi Winter Test", BYD looked up to the U8 with a battery life achievement rate of 85.08%, ranking first, the new M7 test results were poor, with a range achievement rate of only 31.6%, and many models under Geely and Great Wall had a range achievement rate of less than 40% in the test.
In the "Part-of-Road Elk Test", the Leopard 5, Mercedes-Benz EQE SUV, Tank 400 Hi4-T, Xpeng G6 and Smart Elf #3 all passed the test, while the Lynk & Co 08EM-P and Wenjie M7 failed the test.
The host of the Chedi Winter Test Open Day said in the live broadcast: "The weather of minus 40 °C is quite different from the minus 20 degrees tested before, but through the consistency of the process, a relatively objective result is ensured." ”
According to the content of the live broadcast, the car emperor announced the test process during this test, that is, the vehicle will be started at the same time after standing for 3 hours under full power and full fuel, and the battery life test will start after preparing and installing the shooting equipment before the test, and the vehicle air conditioning will be set to automatic 24 °C, and the formation vehicle will exit the test after driving until the engine starts.
Judging from the process of live broadcast, compared with the previous test conditions, the temperature in Mohe on December 14 was lower, reaching about minus 40 °C, due to the severe cold weather, the suction cups, double-sided tape and other auxiliary equipment used to install the instrument were hardened due to the extremely low temperature, and the vehicle needed to turn on the air conditioner after powering on to soften and install. The live broadcast showed that the setup time for installing the test equipment and filming equipment was about 80 minutes.
Great Wall Motors spoke again:
It will open up its new energy environmental testing capabilities to the whole industry
In fact, the results of the "Extended Range/Plug-in Hybrid Pure Electric Endurance Test" that have been completed in the "2023 Chedi Winter Test" have caused great controversy. Yu Chengdong, Executive Director of Huawei, CEO of Device BG, and Chairman of Intelligent Vehicle Solution BU, and Yang Xueliang, Senior Vice President of Geely Holding Group, both questioned their test results. Among them, Yu Chengdong posted in his personal WeChat circle of friends: "The test of pit people! Science and rigor are the basic rules that should be followed!" Yang Xueliang posted: "I also disagree with the evaluation results of the "2023 Winter Test of Understanding Chedi" hybrid models released by Chedi. I also think that the evaluation process is unscientific and rigorous, and the conclusions are not convincing, which not only misleads consumers, but also hurts the credibility of Chedi itself. ”
In terms of car companies, AITO Auto released "Fearless of Severe Cold, Official Interpretation of the Winter Test Performance of Wenjie Series Models" through its official Weibo on the evening of December 8, saying that "under the extreme cold limit and continuous heating conditions of air conditioning, (the above-mentioned media test) has repeatedly opened windows and doors for a long time, which seriously deviates from the real use scenarios of users."
Great Wall Motors posted through its official Weibo that Great Wall Motors retrieved the background data of the tested models for confirmation, and found that some of the results were abnormal, and questioned the results of the "pure electric endurance test", "power loss fuel consumption test" and "climbing test" of the car emperor.
On December 14, after the end of the open day of the winter test of Chedi, Great Wall Motors once again posted through its official Weibo that it would open its new energy environmental testing capabilities to the whole industry. "Great Wall Motor adheres to high-quality development, opens up its new energy environmental testing capabilities to the whole industry, promotes more scientific, professional, rigorous and fair testing of China's new energy vehicles, and promotes the healthy and sustainable development of China's automotive industry. Great Wall Motor said.
"The limit test conditions address the reliability of the vehicle, while the common test conditions address the vehicle's economy. At the "Roundtable Forum on Jointly Improving the Environmental Testing Level of China's New Energy Vehicles" held on December 14, Mu Feng, President of Great Wall Motors, said that the test standards for new energy vehicles should achieve three integrations: one is to achieve the integration of electrification and intelligence, the second is the integration of use scenarios, the working conditions should cover most of the driving conditions, and the parameters should fit the scene, and the third is that the environmental conditions should integrate background parameters such as temperature, humidity and altitude.
