As we all know, for electric vehicle owners, daily endurance anxiety actually occupies only part of the car experience, the biggest problem is that the owners of the north to winter, almost all electric vehicles are bound to face the reality of a large reduction in battery life! Some time ago, there was a domestic head of the automotive media platform for a variety of electric vehicle products for winter endurance test, through the results, in fact, compared to a few years ago, although manufacturers on the battery technology, charging technology, discharge technology, etc. have been innovated, at least in the external expression of innovation, but the winter endurance sharply reduced, is still almost all electric vehicles are still difficult to cross the hurdle!
A few days ago, China Automobile Research Institute announced the results of the winter mileage of six electric vehicles, and the results of the endurance made us extremely disappointed to see that electric vehicles have developed in the domestic market for several years, and intelligence and safety have been qualitatively improved, but in the most core power battery, there is no substantial progress! Everyone is flaunting how much their battery range has increased, but under the cold winter, the 30% endurance reduction rate is already the best performance. It can be said that most of the actual endurance of electric vehicles in winter, compared with the nominal endurance, have shown a "waist chop" general performance!
Tesla Model 3 should be one of the best-selling products in the domestic pure electric sedan, the latest Tesla Model 3 standard endurance version of the nominal mileage of 556 kilometers, China Automobile Research Institute measured the normal temperature range of 520 kilometers, and in the low temperature environment of the cruising range of only 328 kilometers, the cruising rate of up to 36.9%, and the absolute mileage drop of more than 200 kilometers!
Weilai EC6 sports version of the nominal mileage of 465 km and 605 km, the model tested by China Automobile Research Institute should be an entry-level model of 465 kilometers, the normal temperature cruising range measured by China Automobile Research is 424 kilometers, while the winter low temperature cruising range is 245 kilometers, the mileage reduction rate is as high as 42.1%, and the winter mileage of 245 kilometers is really a bit difficult for high-end electric vehicles priced at more than 350,000 yuan!
Xiaopeng P7 ultra-long endurance model of the official nominal mileage of 706 kilometers, China Automobile Research Institute measured the normal temperature cruising range of 698 kilometers, the overall endurance retention rate is still quite high, but the winter endurance performance is also very "bleak", the winter low temperature mileage is only 403 kilometers, the endurance drop rate is as high as 42.4%, from the perspective of absolute mileage, the endurance is 300 kilometers lower than the nominal, and the endurance "moisture" is too large!
BMW iX3 leading type of the nominal range of 500 kilometers, China Automobile Research Institute measured the normal temperature range of 546 kilometers, there is a situation where the actual endurance is longer than the nominal endurance, of course, this is not surprising, it is very likely that the latest endurance standard used by China Automobile Research Institute, compared with the NEDC standard, may be a little more, which has been reflected in the Model 3 standard endurance version! The car's cruising range in the winter temperature is 346 kilometers, and the mileage reduction is 36.6%.
Nezha U Pro 500 lunar version of the official nominal mileage of 500 km (NEDC standard working conditions), China Automobile Research Institute test of room temperature cruising range of 550 kilometers, may be the same as BMW iX3, China Automobile Research Institute is the CLTC comprehensive working condition calculation method, so there is a situation of endurance growth. But despite this, the car's winter mileage is only 317 kilometers, and the mileage drop is as high as 42.4%.
In the winter of last year, BYD Han EV also encountered complaints about the sharp reduction in battery life, but in terms of the test results of China Automobile Research Institute, compared with the above models, the winter endurance decline rate of this car is the lowest! The nominal cruising range of the PREMIUM version of the BYDHan EV ultra-long endurance version is 605 kilometers, the normal temperature cruising range measured by China Automobile Research Is 629 kilometers, and the mileage of the low temperature in winter is 435 kilometers, and the cruising rate is only 30.9%, and the performance is relatively more reliable!
Of course, we also saw some details, that is, although China Automobile Research Institute conducted endurance tests and comparisons on several pure electric models, the overall conditions were not set very harshly! We see that the room temperature is set to 23 degrees above and below 3 degrees, which is actually a not low temperature, can also be considered to be a more rational operating temperature of electric vehicles, and the low temperature is set between minus 10 degrees and minus 4 degrees, in fact, after entering the winter, north of the Qinling Huai River, most of the temperature is far below this temperature range, especially In Xinjiang, Tibet, Qinghai, Gansu, Ningxia, Inner Mongolia, Hebei, Heilongjiang, Liaoning, Jilin and other provinces and cities, the temperature may be much lower than this temperature range. Therefore, the test conditions of China Automobile Research Institute are still relatively tolerant, if the temperature conditions of winter endurance are a little harsher, then the winter mileage of some of these models may be even more "unbearable"!
So in fact, from the media and institutions on the winter mileage of electric vehicles test point of view, electric vehicles for the overall northern owners, friendliness is still very insufficient, especially for many owners who only have one electric vehicle, no oil car owners, may be winter endurance anxiety compared to other seasons, much more obvious!
