Fast Technology reported on December 11 that the emperor of the car really turned over the anger of the public this time.
After Huawei's Yu Chengdong publicly angrily criticized the car emperor, Great Wall and Geely have gone down one after another, and Great Wall Motors has just released the "Initiative on Jointly Building New Energy Test Standards".
Great Wall Motor said:
Recently, some of the test results of the "2023 Chedi Winter Test" have aroused heated discussions among the industry and users. Knowing that Chedi evaluates from different perspectives and scenario applications, which is beneficial to the prosperity and development of China's automobile industry, Great Wall Motors retrieved the background data of the tested models for confirmation, and found that some of the results were abnormal:
1. Pure electric endurance test:
We agree that the car emperor released the test preparation time yesterday, the maintenance is a very important step to ensure the fairness and accuracy of the test, Great Wall Motors in the pure electric range test, it also takes about 1 hour of maintenance time, during the maintenance period is not high-voltage, the power consumption is very small.
The test is to turn on the high voltage and turn on the air conditioning for maintenance, which lasts from 60 to 72 minutes, and at the same time, each model has more than ten times to open and close the door and open the window.
According to the background data analysis, there is a consumption of 5-8 kWh.
Considering that the winter test is prepared in a low-temperature environment, turning on the air conditioning 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 a full state after the maintenance is completed and then carry out the pure electric range test, or calculate the pure electric range according to the proportion of power consumption in the actual driving test.
2. Power loss fuel consumption test
The analysis of the data of fuel consumption of the loss of electricity found that after the completion of the fuel consumption test of each model, the idle waiting time for refueling is different, and the fuel consumption of individual models reaches 34 minutes, and the fuel consumption in this process is about 072l。
For whether this part of the fuel consumption is offset in the final fuel consumption results, after communicating with the car emperor, has not yet received a clear reply, at the same time, the average speed will also affect the test results, the four cars participating in the test from 50There is a big difference between 2 km h and 71 km h.
It is recommended that the test process be tested at the same speed, and the power should be turned off during the waiting for refueling after the test is completed to avoid fuel consumption, and if you need to wait for refueling for a long time, it is recommended to deduct the fuel consumption during the idle waiting period.
3. Climb test:
In the ramp-up test link announced by Chedi, it has been clear that the remaining power of the models participating in the test is greater than 50%.
Through the background data restoration, it was found that the remaining power of the Blue Mountain climbing test was 23%, which affected the output power of the battery and failed to give full play to the real climbing ability.
Great Wall Motor said:
It is the common mission of China's automotive industry and automobiles to build and choose good cars for users, and Chinese car companies go overseas to face the world's big test, shouldering the responsibility of supporting the country to "build a foreign-related legal system and capacity that is compatible with the requirements of high-quality development and high-level opening-up".
*The evaluation is a supervision and a spur, bringing a new perspective to China's automotive industry and allowing more users to pay attention to China's new energy vehicles.
We 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.
Provide global users with more rigorous, fair and objective evaluation results, and promote the high-quality development of China's automotive industry.
