Recently, the company held a high-profile winter test event, which attracted widespread attention from the car rim. After the release of the first test results, some manufacturers were dissatisfied with the test results of the Chedi and criticized the fairness of the test. In order to clarify this controversy, the company decided to conduct a second test and invited a number of car companies and ** witnesses. With the participation of many ** and car companies, several controversial models were tested live. After the release of the second test results, the lower-ranked car companies did not speak out again, thanks to a large number of ** and car company witnesses, making the test results more fair and transparent.
The results of the second test once again proved the impartiality of Chedi. Although some people have questioned the method of testing, arguing that the test scenario is too extreme, and that such cold temperatures rarely occur in real car situations, the significance of the test remains. Whether it is a hybrid model or a pure electric model, the range performance in extreme cold conditions is greatly reduced. In temperatures of more than minus 20 degrees, the range of electric vehicles will be reduced to less than half of the original. In addition, the performance of many electronic devices will be affected in extremely cold environments, and electric vehicles are more susceptible to interference from extreme cold weather due to the large number of electronic devices. Therefore, regardless of whether the test standards are in line with the actual situation, it can at least be concluded that it is still more reliable to buy a fuel car when driving in the north.
In the northern region, extremely low temperatures are common, which brings some problems to the use of electric vehicles. According to the test results of the winter test of the car emperor, the endurance performance of the electric vehicle in the extremely cold environment is obviously not as expected. There are several reasons for this.
First of all, the operating environment of the battery has a significant impact on the range of the electric vehicle. In extremely cold weather, the performance of the battery will be greatly reduced, resulting in a direct impact on the range of the electric vehicle. In particular, due to its structural characteristics and material properties, the traditional lithium-ion battery has a weakened charge conduction ability at low temperatures, resulting in a decrease in the battery energy storage capacity, which affects the endurance performance of the vehicle.
Secondly, the energy consumption of electric vehicles mainly comes from the electricity provided by the battery, and in extremely cold environments, the energy required by electric vehicles to maintain the normal operation of the vehicle will increase. Because the battery's energy storage capacity in cold environments is reduced, electric vehicles need to consume more electricity to maintain range in order to compensate for the impact of reduced energy consumption. This means that in extremely cold weather, the range of electric vehicles is significantly shortened.
Finally, extremely low temperatures also have a negative impact on battery life. The life of an electric vehicle battery is closely related to the operating temperature, and too low a temperature will lead to an increase in the internal resistance of the battery and a decrease in the rate of battery chemical reactions, thereby accelerating the aging of the battery. Continued use of electric vehicles in extremely cold environments can adversely affect the life of the battery, further affecting the vehicle's range performance.
Based on the test results of the winter test and the above problems, we can conclude that in the extremely cold environment of the northern region, it will be more secure and reliable to buy a fuel vehicle. First of all, because fuel vehicles use fuel to provide power, they are not directly limited by the ambient temperature, so their endurance performance is stable and will not be disturbed by extremely cold weather. At the same time, the start and operation of fuel vehicles in extremely cold environments are more reliable, and there are no problems such as insufficient battery power and difficulty in starting that electric vehicles may encounter.
In addition to the advantages of range and reliability, fuel vehicles also have a more mature charging infrastructure. In contrast, the coverage of EV charging infrastructure in the northern region is relatively low. In extreme cold weather conditions, EV owners may face inconvenient charging, which will also affect the normal use and range of the vehicle.
In addition, fuel vehicles also have obvious advantages in terms of cold start and heating. In extremely cold weather, fuel vehicles can quickly reach a suitable temperature through the heat generated by the internal combustion of the engine, providing a comfortable driving environment. Electric vehicles, on the other hand, rely on batteries to provide electricity for heating, which leads to increased energy consumption and shorter range.
To sum up, whether in terms of range, reliability or charging infrastructure, it is indeed more reliable to drive and buy fuel vehicles in the northern region. Although electric vehicles have certain advantages in terms of environmental protection and energy saving, their performance in extremely cold environments is not ideal, and further development of technology and infrastructure is still needed to meet the needs of users in the north.
As a fan who pays attention to the automotive industry, I know that Chedi's winter test activities have provided me with a lot of valuable information. Through the test results, I realized that the range of the electric vehicle in the extreme cold environment of the northern region was indeed lower than expected. This also makes me better understand why in the northern region, fuel vehicles are still the mainstream choice.
However, I also have to admit the advantages of electric vehicles in terms of environmental protection and energy saving. The market share of electric vehicles is growing, and the technology is constantly advancing. With the improvement of battery technology and charging infrastructure, I believe that electric vehicles will improve in terms of reliability and range in the northern region in the future.
In general, the winter test activity once again reminds us that we need to choose a reasonable model according to the climate and needs of our own region when buying a car. Users in the northern region can learn from the test results of Chedi and choose the fuel model that suits them on the premise of ensuring reliability and endurance. At the same time, as a means of clean energy transportation, electric vehicles also have broad market prospects, and it is hoped that manufacturers and technicians can continue to work hard to solve the problem of electric vehicles in extremely cold conditions and provide consumers with better choices.
