IT Home reported on December 14 that the current "winter test" controversy has sparked heated discussions on the whole network, including Huawei, Great Wall Motors, and Geely have questioned the test standards.
According to the "Automobile" magazine, Dr. Wang Yao, assistant secretary general and director of the Technology Department of the China National Association, said in an interview that the healthy development of the automotive industry requires the establishment of a scientific and standardized new energy vehicle evaluation system. The China Association is cooperating with industry enterprises and professional testing institutions to jointly formulate new energy vehicle evaluation standards, and plans to release them in the form of association group standards.
Tesla** reported on the article and said, "Our global engineering team conducts a large number of extremely rigorous extreme cold tests every year to ensure the reliability of our products. As the association said, testing outside of industry standards is misleading to the public and consumes public resources. Whether you're considering buying a Tesla or not, we invite you to come to the store for a test drive, and your real experience is the most important thing. ”
IT Home summarizes the timeline of the "2023 Chedi Winter Test" event:
Recently, we have conducted winter performance tests on dozens of new energy vehicles, involving the performance of pure electric vehicles and hybrid vehicles in many fields. The test site is located in Mohe, which is currently in extremely cold weather. In the plug-in hybrid group's "pure electric range achievement rate" project, the M7 is only 3160% achievement rate. (The Warrior 917, Navy S7 Extended Range Edition, and Trumpchi E9 PHEV cannot be driven in pure electric mode in the extremely cold environment of -30 and will not be counted in the score).
Last Friday, AITO explained the test in detail: Tests** confirmed that the vehicle was heated by air conditioning for a total of 71 minutes before the official test, and then heated for another 40 minutes after the temperature inside the car reached 24 degrees Celsius.
In this process, there are more than ten operations to open and close the doors and windows, of which the longest time is more than 3 minutes, which greatly increases the energy consumption of the air conditioner and causes the power to drop rapidly. Under the extreme cold and continuous heating conditions of the air conditioner, the windows and doors are opened for a long time many times, which seriously deviates from the user's real usage scenario.On December 10, the car emperor said: The test standards are completely unified, and all models are treated equally!In addition, the vehicle had 74 remaining charge at the time of testing9%, with the driver and 4 60kg sandbags on board, the test started until the battery level was 20The range extender starts at 4% and actually consumes 54 battery power5% to achieve a pure electric range of 55 in extreme weather conditions in winter3 km.
Late at night on December 10, it was reported that Yu Chengdong also expressed his position on the test results of Wenjie M7's participation in the "2023 Chedi Winter Test" in the WeChat circle of friends: The test of the pit people misleads the public!Science and rigor are the basic rules that should be followed!
At noon on December 11, Great Wall Motor announced that it would hold a communication meeting on the winter test standard of Che Emperor at 15 o'clock on December 14.
Victor Yang Xueliang, senior vice president of Geely Holding Group, joined the "battlefield", saying that the evaluation process was unscientific and rigorous, and the conclusions were not convincing, which not only misled consumers, but also hurt the credibility of Chedi itself.
Understand the car emperor responded to the "winter test" standard was questioned: this test is a full-load endurance test in extremely cold weather below -20, and all participating vehicles set off in formation after maintenance, using a unified standard, in line with the user's winter car scene, and there is no discrimination.
Knowing Chedi invited 39 car companies to observe the site at 9 a.m. on December 14.
On December 12th, Knowing Chedi issued a statement on some of the false content related to the release of "Understanding Chedi Winter Test", and has collected evidence from multiple accounts such as "hw ex-HR" and "Science and Technology Dog Jiange" and reported them to relevant departments, and reserves the right to further pursue legal responsibility.
On December 13th, the background data of VOYAH FREE's "Know Chedi Winter Test" was announced: the left front window was not closed for 1328s.
