Recently, Dongchedi conducted a winter test of new energy vehicles. This news caused heated discussion in the car circle:
The pure electric range of U8 is 124 kilometers, and the battery life rate is 85%.
The pure electric range of Qin Plus is 112 kilometers, and the battery life achievement rate is 34%.
Why is there such a huge gap in pure electric battery life between batteries from the same manufacturer?
According to Wenjie and Great Wall, there is something wrong with the testing standards of Car Emperor. Or according to netizens, BYD intervened in the car-savvy emperor. So why is Qin’s battery life achievement rate still so low?
There are two main reasons: battery capacity and battery management strategy.
Although both cars have a pure electric range of more than 100 kilometers, in fact, the battery capacity of the Yangzhan is as high as 50 kilowatt-hours, while the battery of the Qin Plus is only 18 kilowatt-hours.
In the winter test of Chedi, air conditioning heating consumes a lot of heat. This kind of heat consumption is negligible for high-capacity batteries, but for Qin Plus, it appears to be relatively fatal.
In fact, the same situation existed during summer testing. In this summer’s test, Avita 11 ranked first in battery life because it has a large 116-degree battery, so the energy consumption of the air conditioner has little impact. The battery of the last Wuling Mini is only 13.4 degrees, and the air-conditioning energy consumption greatly reduces the cruising range.
By the way, why is the battery life of Wenjie M7 so poor? Wenjie M7 uses a 40-degree battery with a nominal battery life of 210 kilometers and a WLTC battery life of 175 kilometers. The Denza D9 also uses a 40-degree battery, but its nominal battery life is only 145 kilometers.
It’s simple, the smaller the denominator, the higher the completion rate.
Another issue is the manufacturer’s settings. It was mentioned in the “Knowing Car Emperor” program that in forced EV mode, starting the engine is considered to be the end, not that the battery is exhausted. The engine of Wenjie M7 is forced to intervene in heating at 55 kilometers. This is just a setting. Maybe Yu Dazui himself does not know the specific setting of the engineer.
The above is the explanation for the difference in battery life achievement rate between U8 and Qin Plus. Hope this helps.
