Although I have always disliked Yu Chengdong's words, this time "Yu Dazui" still threw out a topic for the automotive industry - who has the final say in the test of new energy vehicles.
As we all know, one stone stirs up a thousand waves.
After the release of Chedi's 2023 winter test**, Huawei, Great Wall Motors and Geely have raised questions, accusing them of unfair results because they did not treat everyone equally.
Yuguan Auto Market believes that regardless of whether the Chedi 2023 winter test is "mixed with water" or not, the evaluation itself is a serious matter. As a first-class platform "both as an athlete and as a referee", it is difficult to avoid "greasy" and power rent-seeking, not to mention, understand the car emperor is also facing the problem of whether it is professional, it itself does not have testing qualifications, and does not have the professionalism of testing, and there is no rigorous standard in the testing process, such a "three no" testing is unfair to the enterprise, but also misleading to consumers, in the long run, it is not conducive to the development of the industry, and even if it is a car company with high scores, it is also because the test data is "out of common sense" And have to feel embarrassed.
The data deviates from common sense, and BYD is also embarrassed!
In a large group of 500 people, someone ridiculed: "It is estimated that the owners of Dizi cars in Hainan can't drive more than 80% of the battery life in winter, but they have done it in Mohe." ”
In the new phase of the winter test, the pure electric range achievement rate of about 20 hybrid models in severe cold conditions was tested. Among them, BYD looks up to the first, 8508% endurance achievement rate;The M7 extended range version jointly designed by Cialis Automobile and Huawei is the penultimate one, only 316%。In addition, BYD also occupies three of the top five places in the list of endurance achievement rates.
The results caused an uproar.
Yu Chengdong, Executive Director of Huawei, CEO of Device BG, and Chairman of Intelligent Vehicle Solution BU, immediately "jumped up" and counterattacked, calling it "a test of pit people!".To mislead consumers, science and rigor are the basic rules that should be followed!And rushed to the hot search.
Geely Group's senior vice president @杨学良victor posted on Weibo on the afternoon of the 11th, believing 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.
Great Wall Motors announced on its official blog that it will hold a communication meeting on December 14 at 15 o'clock in Beijing to understand the winter test standards of the car emperor, including the scientific and fair standards of the new energy winter test, the vehicle maintenance standard of the pure electric range test, the vehicle power standard of the climbing angle test, and the vehicle braking standard of the climbing distance test.
How can there be new energy vehicles minus 20 degrees and the achievement rate is 8508% of ?It's so embarrassing and defies common sense!Most of the comments in the industry understand the doubts of the above-mentioned car companies, after all, this set of data is really unconvincing, and even deviates from common sense.
A little common sense knows that in winter, it is normal for the battery range to decline, especially the lithium iron phosphate battery, before, Tesla was troubled by this, because the winter range attenuation problem of the Tesla Model 3 of the lithium iron phosphate battery is very serious.
In most tests, in an environment of minus 20 degrees, the endurance of lithium iron phosphate batteries will drop to about 50% of the normal temperature.
Previously, BYD also admitted that the blade battery used in the U8 had a discharge efficiency of 90% at room temperature at minus 20 degrees. In other words, even if the battery life can reach 90% in normal times, it can only reach 81% at most when it is minus 20 degrees, which is difficult to achieve in daily use scenarios.
In the era of intelligence, "it is difficult to hide dirt in the sun".
The key point that arouses the doubts of automobile manufacturers is that although the car emperor explains in the ** that it is "full power and full fuel" to stand overnight, and "to power on and prepare for the same time", however, each manufacturer finds that there is no unified standard according to its own network data.
As pointed out in an article released by AITO Auto's official WeChat: "After testing**, it was confirmed that the vehicle was heated by air conditioning for a total of 71 minutes before the official test, and after the temperature in the car reached 24 degrees Celsius, it continued to heat for another 40 minutes. In this process, there are more than ten times to open and close the doors and windows, the longest of which is more than 3 minutes, which greatly increases the energy consumption of the air conditioner and leads to a rapid drop in power. 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. ”
Yang Xueliang also said on December 11 that according to the data retrieved by our background, Geely Galaxy L6 In the maintenance process before the test, the vehicle idled in place for 70 minutes, during which the door was opened 4 times, and the longest two door openings took more than 10 minutesThe Lynk & Co 08 was idle in place for 71 minutes before the test, during which the doors were opened six times, with the longest opening time being 6 minutes and 39 seconds. These operations have greatly increased the energy consumption of the air conditioner, resulting in a significant drop in the vehicle's power before it is officially issued.
In the face of doubts, Chedi said: "The test standards are completely unified, and all models are treated equally. However, as of the press release of Yuguan Auto Market, BYD did not stand up to "testify" for the emperor who understands the car, and it is impossible to judge whether it is "treated equally". Judging from the data provided by the above three car companies, there are also certain differences in the idle opening time during the maintenance period.
In fact, the best thing that can prove the "innocence" of Chedi is BYD, and it is completely possible to publish background data. After all, if the error is not large, at least there is no understanding of Chedi's "deliberately misleading" manipulation of data, and "laxity" and "cheating" are completely different practices.
At the same time, the exposed problem is that with the advent of the era of smart cars, manufacturers can also remotely grasp the data of their own vehicles, relatively speaking, more transparent, fair and just, but even so, for consumers, the current identification of new energy vehicle test results is still "in the clouds" true and false difficult to distinguish, as a new thing, new energy vehicle testing is facing the lag of policies and regulations, and the evaluation agency is mixed, how to evaluate consumers?
Who has the final say in the detection of new energy vehicles?
As a first-class platform, if it is truly fair, to a certain extent, although it is not authoritative, it is also a data that can be worthy of reference, and it can also be recognized and trusted by the industry and consumers. However, because the detection itself is associated with huge benefits**, it is easy to walk and change the taste.
In the past, because of the huge traffic of Chedi itself, the manufacturers and its previous "lips and teeth" were "interdependent", and the individual traffic of the manufacturers could not compete with it, so even if there were objections to the evaluation, the OEMs would not take the initiative to question them publicly, and generally "solve them privately" in order to have better data in the coming year. But now that Huawei is here, Huawei, which has mastered the secrets of traffic, can be on the hot search at every turn, which makes the platform more and more difficult.
Jiang Zhaorong, founder of AutoCarweekly, wrote in his circle of friends:
I think it's better not to do the best work. Being an athlete and a referee, of course, you can make a lot of money, but in fact, this model doesn't sound long, isn't it just a huge version of Li Jiaqi. Even if this is a misunderstanding, in the long run, monopoly will inevitably corrupt. In addition to political tasks, it is better for the platform not to end up on its own. Could it be that Weibo also has to run its own one or two hundred big Vs to dominate the hot search, and WeChat also has to produce thirty or fifty heads to brush millions every day?The winter test is also open, so what is the good ranking for M7?Give a good ranking, that's not a slap in the face, and then give a bad one, I'm not afraid of being slapped by Huawei again?
I agree with that, and right now, the platform itself is a dilemma. The exposure of this matter will make it more and more difficult for the platform to be used as a third-party testing agency. In this process, it is equivalent to Huawei supervising test platforms such as Chedi as a strong traffic**.
In fact, it has always been difficult to maintain fairness and justice when it comes to car testing, because the interests are too complex. As before, China Automotive Research Institute has always been nicknamed the "five-star wholesale department", and although China Insurance Research Institute appeared as a fair person under the guise of "not making profits", and hit the Passat with a 25-degree bias as soon as it came up, it also showed its true face as time went by.
But in any case, in the testing of fuel vehicles, whether it is the China Automotive Research Institute or the China Insurance Research Institute, at least refer to the European standard and the American standard. On the other hand, if you understand the winter test of the Che Emperor, whether it is fair or not, anyone with a discerning eye can see that it is too casual.
In this regard, on December 11, Great Wall Motor also released the "Initiative on Jointly Building New Energy Testing Standards" on the WeChat official account, saying that it will call on and will make every effort to promote the joint efforts of China's automotive industry regulators, car companies, evaluation agencies, and users to formulate new energy testing standards that are more suitable for users' actual application scenarios, actual environmental conditions, and actual working conditions, so as to provide global users with more rigorous, fairer, and more objective evaluation results, and promote the high-quality development of China's automotive industry.
From this point of view, Huawei's Yu Chengdong's anger is likely to accelerate the authoritative scientific testing of new energy vehicles
