In the winter test, the endurance achievement rate of new energy vehicles is at the bottom of the M7 official background data restoration test
Fast technology news on December 9, recently, the domestic vertical automotive media "understand the car emperor" on the current market of new energy vehicles for winter testing, many results have been announced, including in the plug-in hybrid group pure electric battery life achievement rate, there are cars that are surprising.
According to the official results released by Chedi, the first place is Yangwang U8, with a pure electric mileage rate of 85.08% in the test, followed by three models that are also from BYD, namely Song PLUS DM-i, Denza D9DM-i and Tang DM-i.
Among the test cars with achievements, the endurance achievement rate of the M7 is only 31.60%, which is the last place.
After the results were announced, many netizens felt that the performance of the question world was too stretched, and the ternary lithium battery was used, and even the models using lithium iron phosphate could not be compared with the models under low temperature conditions, so they were disappointed.
So what happened during the test? Yesterday evening, AITO Automobile released the "Fearless Cold, Official Interpretation of the Winter Test Performance of the Wenjie Series Models", which explained and responded to the content of battery life, and officially said:
According to the results of the "Unified WLTC4 Standard Pure Electric Range Achievement Rate of Plug-in Hybrid Group", the pure electric range of the new M7 is 55.3 kilometers.
The test media confirmed that the vehicle was heated by air conditioning for a total of 71 minutes before the official test, and after the temperature inside the vehicle 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.
In addition, it is worth noting that the test was only started when the vehicle was only 74.9% powered, equipped with the driver and four 60kg sandbags, and the range extender started when the power was 20.4%, and the actual battery power consumption was 54.5%, achieving a pure electric range of 55.3 kilometers under extreme weather conditions in winter.
It should be noted that there is a key point in the above response: it has been confirmed by the test media.
That is to say, the car emperor recognized the background data given by the question, and confirmed that a total of 111 minutes of air conditioning heating did occur before the test, and the doors and windows were opened many times on the way.
Due to the fact that the body is full of sensors and the unified use of EDR black boxes, new energy vehicles can record every move in the test process in more detail, so it will only become more and more difficult to achieve certain goals through some means.
