Wenjie, the Great Wall, and Geely have spoken out successively and do not agree with the results of the winter test of Che Di
DoNews reported on December 11 that recently, the test results of the pure electric range achievement rate of winter hybrid models announced by Chedi have caused controversy among car manufacturers. After the question community took the lead in questioning it, Great Wall and Geely also spoke out one after another.
According to Jiemian News, about 20 models participated in the test, including BYD Yangwang and Wenjie M7 extended range version. Among them, BYD looks up to the top of the list with a range achievement rate of 85.08%, and the M7 extended range version is at the bottom with a completion rate of 31.60%.
In addition, Geely's two models are at the bottom of the list, and Great Wall Motor's three models are in the middle position.
According to the test method published by Chedi, the test is divided into two stages: preparation and testing. All vehicles are fully fueled and charged the day before the test, and then left in an environment of minus 20 degrees Celsius overnight, followed by an hour of maintenance before the test the next day.
During the formal test, the pure electric mode will be turned on when the air conditioner is turned on, and then the fuel consumption test will be tested with full fuel.
In response to the fact that the M7 is at the bottom of the ranking, the official official account of the Wenjie was the first to release an article saying that the air conditioning heating time of the vehicle in the formal test and maintenance stage is too long, and there are more than ten times of opening and closing the doors and windows in this process, which greatly increases the energy consumption of the air conditioner and leads to a rapid decline in power.
In the official opinion of Wenjie, under the extreme cold and continuous heating conditions of air conditioners, the windows and doors have been opened for a long time many times, which seriously deviates from the real use scenarios of users.
Yu Chengdong, chairman of Huawei's intelligent vehicle solution BU, also questioned the rigor of the test rules in Moments, saying that "science and rigor are the basic rules that should be followed".
Great Wall Motors said that Great Wall Motors retrieved the background data of the tested models and found that some test results were abnormal. In addition, Great Wall Motor's official blog announced that it will hold a communication meeting on December 14 in Beijing to question the winter test standards of Che Di.
Subsequently, Yang Xueliang, senior vice president of Geely Holding Group, also said on Weibo that he did not agree with the evaluation results of the pure electric range achievement rate of hybrid models released by the "2023 Winter Test". "I also think that the evaluation process is unscientific, not rigorous, and the conclusions are not convincing, which not only misleads consumers, but also hurts the credibility of Chedi itself. ”
