Shulou(Shulou.com)12/24 Report--

Thanks to CTOnews.com netizens for the delivery of clues about the past. CTOnews.com, December 11, after the Great Wall Automobile announced that it would hold a communication meeting at 15:00 on December 14 to question the standards of understanding car Emperor Winter Test, Great Wall Automobile once again issued an initiative to jointly build China's new energy test standards, and put forward suggestions on part of the test process of "2023 understanding car Emperor Winter Test".

The pure electric endurance test understands that the Chedi test is to turn on high voltage and air conditioning for preparation, with a duration ranging from 60 to 72 minutes. at the same time, each vehicle model also has more than a dozen times to open and close doors and windows, and some models have the heating of open seats. The above operations all affect the power consumption before the test.

According to the background data analysis, there is a consumption of 5-8 kilowatt-hours of electricity, considering that the winter test is prepared in a low temperature environment, turning on the air conditioner is a necessary humanized measure, but in order to ensure the fairness and accuracy of the test, it is recommended to charge the vehicle to the fully charged state after the completion of the test, or to calculate the pure electricity range according to the proportion of power consumption in the actual driving test.

Based on the analysis of the fuel consumption data of power deficit fuel consumption test, it is found that after completing the fuel consumption test, the idle waiting time for refueling is different, individual vehicles reach 34 minutes, and this process consumes about 0.72 liters of fuel.

As to whether this part of the fuel consumption is offset in the final fuel consumption results, after communicating with the understanding car emperor, it has not been clearly replied. At the same time, the average speed will also affect the test results, and the four cars taking part in the test vary greatly from 50.2km/h to 71km/h.

It is recommended that the testing process be tested at the same speed, turn off the power while waiting for the completion of the test to avoid fuel consumption, and if you need to wait for a long time to refuel, it is recommended to deduct the fuel consumption during idle waiting.

The climbing test understands the climbing test announced by Chedi, and has clearly participated in the test that the remaining electricity of the model is more than 50%. Through the background data restore found that the blue mountain climbing test, the remaining power is 23%, affecting the battery output power, resulting in failure to play the real climbing ability.

It is recommended that the same test conditions be strictly observed and the status of the test vehicle should be confirmed before the climbing test.

CTOnews.com summarizes the event timeline of "2023 understanding car Emperor Winter Test":

Understanding car Emperor recently conducted winter performance tests on dozens of new energy vehicles, involving the performance of pure electric vehicles and hybrid vehicles in many areas. The test site is located in Mohe and is currently in extremely cold weather. In the plug-in hybrid group's "pure electric life success rate" project, the boundary M7 only achieved a success rate of 31.6%. (the Mengshi 917, the Deep Blue S7 extended range version and the Chuanqi E9 PHEV cannot drive in pure electric mode in the extremely cold environment of-30 ℃, excluding the results.)

On Friday, AITO explained the test in detail: the test media confirmed that the vehicle was heated by air conditioning for a total of 71 minutes before the formal test, and continued for another 40 minutes after the temperature in the car reached 24 degrees Celsius.

In this process, there are more than ten times 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 air conditioning and leads to a rapid decline in electricity consumption. Under the condition of severe cold and continuous heating of air conditioning, the windows and doors are opened for many times for a long time, which seriously deviates from the real use scene of users.

In addition, the remaining power of the vehicle during the test was 74.9%, and the test began only when the driver and four 60-kilogram sandbags were carried. When the power was 20.4%, the range extender started, and the actual battery power consumption was 54.5%. To achieve a pure electric range of 55.3 km in extreme weather conditions in winter.

Understand the car emperor said on December 10: the test standards are completely unified, all models are treated equally!

Late at night on December 10, it was reported that Yu Chengdong also expressed his position on the test results of M7 participating in the "2023 car King Winter Test" on Wechat moments: deceiving people and misleading 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 to question the winter test standards of Chedi at 15:00 on December 14.

Yang Xueliang Victor, senior vice president of Geely Holdings Group, joined the Battlefield, believing that the evaluation process was not scientific and rigorous, and the conclusion was not convincing, which not only misled consumers, but also hurt the credibility of Zhi Chedi himself.

The standard of understanding car Emperor's response to the "winter test" was questioned: this test is a full-load endurance test in extremely cold weather below-20 ℃. All participating vehicles set out in formation after preparation, using a unified standard, in line with users' winter car scenarios, and there is no differential treatment.
