The last time I knew about Chedi's AEB test, the performance of Huawei Wenjie and Xiaopeng became a hot topic and was talked about by the masses. In this AEB test, Wenjie was clearly ahead of Xpeng and became the winner. And this time, the announcement of the car emperor winter test, the announcement of the endurance results once again caused controversy among car companies. This scene is even more exciting than the previous AEB test, because several car companies have expressed dissatisfaction with the results of Chedi. Yu Chengdong, as a representative of Huawei, has always claimed that Huawei Wenjie is far ahead in terms of battery life, but the test results of Chedi show that the battery life of Wenjie M7 is relatively poor, ranking first from the bottom. As a result, Yu Chengdong expressed his dissatisfaction in the circle of friends, saying that this was a test that misled the public. Great Wall Motors even said that it would hold a press conference to question the test results of the car emperor, and even issued a "Come on!"."Challenge. Yang Xueliang, senior vice president of Geely, also expressed his disagreement with the test results of Chedi. In the face of the provocation of these three car companies, the car emperor did not show weakness, and directly responded that the test standards were completely unified, and all models were treated equally. At the same time, Knowing Chedi also announced that the 2023 Winter Test Open Day will be held in Mohe on December 14, inviting all participating car companies to observe on site and broadcast the whole process live. However, back to the problem itself, since there is no test standard formulated by a real authoritative organization, people do have certain doubts about whether the test results of Chedi are scientific and reliable. Major car companies complain about their poor performance, which is precisely for this reason. But if we assume that the conditions are the same and the test standards are the same, there will still be some cars that perform well and some cars that perform poorly. This reflects the gap between the different models. Therefore, people are looking forward to the live test of Chedi on December 14, when we can see which car performs better. Regardless of whether the test results are trustworthy or not, I think that the test actually lifts the veil of new energy vehicles, that is, in cold winter conditions, the range of these so-called electric vehicles will be greatly reduced. Some so-called black technologies may not be able to withstand the test of low temperatures. No matter which brand of new energy vehicle company, the efficiency of the battery will decay in cold conditions, resulting in a significant reduction in mileage. This is a problem with the battery material itself, some batteries may perform better, and the mileage may only be discounted by 20%, and some may even be less than 5% off. In addition, in cold climates, many so-called high-tech can also be affected. This is exactly what electric vehicles must face up to at the moment. China is a vast country, and the climatic conditions in the north and south are completely different, so we have to take into account the experience of driving in extremely cold conditions. Therefore, regardless of whether the test is reasonable and the standard is accurate, as long as it can promote major car companies to pay attention to performance and endurance in cold conditions, then this test will be considered successful. This is undoubtedly far-reaching, what do you think?
In the winter test of knowing the car emperor, the release of the endurance results caused dissatisfaction among car companies. This also makes us have to pay attention to the performance of electric vehicles in the cold winter months. Whether or not we believe the test results of Chedi, perhaps we can reflect on the condition of electric vehicles in cold conditions.
1.Battery performance degradation: During cold winter temperatures, the battery efficiency of electric vehicles can be significantly reduced. This is because the chemical reaction of the battery becomes sluggish at low temperatures, resulting in a weakened capacity of the battery to store electricity. As a result, many electric vehicles have reduced range in the winter. Some models with better battery performance may only lose some of their range, but some models even have a 50% discount on mileage. This shows that the adaptability of the battery material itself at low temperatures needs to be improved.
2.High-tech limitations: In cold conditions, many so-called high-tech are also affected. For example, the powertrain of some models may become unstable due to low temperatures, resulting in poor acceleration or uneven power delivery. In addition, some electronic devices and sensors may also be affected by low temperatures, which can degrade the performance of some safety assistance systems. Therefore, in the case of use in extremely cold conditions, car owners need to pay attention to the reliability and stability of these high-tech systems.
3.Differences between the North and the South: China is a vast country, and the climatic conditions in the north and south are very different. In the cold regions of the north, the range of electric vehicles is particularly prominent. In the warmer regions of the south, the range of electric vehicles is relatively good. Therefore, when choosing an electric vehicle, car owners should reasonably plan the use and mileage of the vehicle according to the climatic conditions of their own location.
Overall, the cold winter is a severe test for the range and performance of electric vehicles. New energy vehicle companies need to make breakthroughs in battery technology to improve the working efficiency of batteries in low temperature environments. At the same time, high-tech systems need to be better adapted to cold conditions to ensure the safety and reliability of vehicles in snow and ice. It is only through continuous R&D and innovation that electric vehicles can truly meet the needs of consumers and provide excellent performance during the cold winter months.
The winter test of Chedi has not only caused controversy among many car companies, but also brought us in-depth thinking about the performance of electric vehicles in cold conditions. For this test, I think there are the following points worth paying attention to and reflecting on.
First of all, in response to the refutation of the test results, we need to objectively evaluate the scientificity and reliability of the test. Although there is currently a lack of testing standards formulated by authoritative institutions, for new energy vehicle companies, such tests have a positive significance for product improvement and optimization. Even if the test has certain flaws, through such a test, car companies can pay more attention to the performance and endurance of electric vehicles in cold conditions, and urge technological progress and breakthroughs.
Secondly, we should also be aware of the impact of the cold winter on electric vehicles. In cold conditions, the performance of batteries and high-tech systems can be significantly affected, resulting in reduced range and reduced vehicle performance. Therefore, electric vehicle companies need to increase investment in battery technology and high-tech systems to gradually improve the performance and reliability of vehicles in low temperature environments.
Finally, it is crucial for consumers to choose an electric vehicle that adapts to the local climatic conditions. The climate in the north and south is very different, and the demand and performance of electric vehicles are also different. Therefore, when buying a car, you should choose the right model and configuration based on the climatic conditions of your own location to get the best car experience.
All in all, although the winter test of Chedi has caused controversy among car companies, it also provides an opportunity for new energy vehicles to pay attention to and solve the problem in cold winter conditions. Regardless of whether the test is completely scientific and reliable, it has promoted the attention of car companies to the range and performance of electric vehicles. Only through continuous testing and research can we continuously improve the performance and reliability of electric vehicles and provide consumers with a better car experience.
