Although car companies will deliberately emphasize the mileage of vehicles when promoting new energy models, as a major selling point of their products, can the mileage of these new energy vehicles remain healthy after facing the current cold wave weather? If the endurance shrinks, what is the difference between the actual endurance in winter and the actual endurance at room temperature?
Recently, China Automobile Research Institute has done a mileage test for these problems, and the test vehicles are 6 models with high popularity in 2021, namely Tesla Model 3 (standard endurance rear-wheel drive upgrade), WEILAI EC6 (sports version), BYD Han EV (ultra-long endurance version premium version), BMW iX3 (leading version), and Nezha U Pro (500 moon version).
6 models in the normal temperature of 23 ° and low temperature -7 ° two temperature environment for endurance test, perhaps many netizens wonder why they will choose minus 7 degrees environment for low temperature test, China Automobile Research Institute also explained that the average temperature in north China in winter is about minus 7 degrees, the choice of minus 7 degrees is also to ensure that the test conditions are consistent with the user's actual use environment as much as possible.
In terms of specific test results, Tesla Model 3 has a cruising range of 520km at room temperature, a low-temperature cruising range of 328km, and a low-temperature actual cruising range of 36.9% compared with the ambient cruising range, according to its 55kWh battery capacity, Tesla Model 3 consumes 16.7kWh per 100 kilometers in a low-temperature environment.
NIO EC6 Sport Edition is the most expensive model among the 6 models, priced at 407,000 yuan, but in terms of endurance performance is not satisfactory, NIO EC6 ambient cruising range of 424km, low temperature environment cruising range of 245km, low temperature actual mileage compared to normal temperature cruising range shrinkage of 42.1%, according to its 70kWh battery capacity to calculate, NIO EC6 in a low temperature environment, 100 km power consumption of 28.5kWh.
BYD Han EV in the case of normal temperature cruising range of 629km, low temperature cruising range of 435km, low temperature actual mileage compared to normal temperature cruising range shrinkage of 30.9%, according to its 76kWh battery capacity to calculate, BYD Han EV in the low temperature environment, 100 km power consumption of 17.8kWh, and Tesla Model 3 in the low temperature environment of the energy consumption is relatively close.
Xiaopeng P7 in the case of normal temperature mileage of 698km, low temperature mileage of 403km, low temperature actual mileage compared to normal temperature mileage shrinkage of 42.3%, according to its 80.3kWh battery capacity to calculate, Xiaopeng P7 in a low temperature environment, 100 km power consumption of 20kWh.
BMW iX3 in the case of room temperature cruising range of 546km, low temperature cruising range of 346km, low temperature actual mileage compared to normal temperature cruising range shrinkage of 36.6%, according to its 80kWh battery capacity to calculate, BMW iX3 in a low temperature environment, 100 km power consumption of 23.1kWh.
Nezha U Pro 500 lunar version in the case of room temperature cruising range of 550km, low temperature cruising range of 317km, low temperature actual cruising range compared to normal temperature cruising range shrinkage of 42.4%, shrinkage percentage and Xiaopeng P7 equivalent, according to its 66.23kWh battery capacity to calculate, Nezha U Pro 500 lunar version in a low temperature environment, 100 km power consumption of 20.9kWh.
From the final test data of 6 models, it can be seen that under the room temperature cruising range, 6 models have a better cruising range, the cruising capacity is more than 400km, but once in the low temperature environment, the mileage of some models has shrunk seriously, of which the product shrinkage of the three new forces of Car manufacturing is the most serious, with an average of more than 42%, and the three models are equipped with lithium iron phosphate batteries supplied by the Ningde era.
It is worth noting that Tesla and BMW iX3, BYD Han EV, two traditional car companies' new energy products that are despised by the new forces of car manufacturing, have achieved more excellent results in low temperature tests, although BMW iX3 is also the battery of the Ningde era, but the battery system is packaged by BMW itself, BYD and Tesla are not to mention, BYD's lithium iron phosphate blade battery and battery management technology has become famous in the world, plus BYD itself is engaged in battery making, Nowadays, the product is so good that many car companies also purchase batteries from BYD, and it is not surprising that it has won the first place in the low-temperature endurance test, Tesla is also famous for its excellent technology integration ideas in battery management.
With the continuous improvement of the penetration rate of new energy vehicles, the product updates of the new car-making forces are becoming more and more frequent, and the days are getting better and better, but now the reputation of the new car-making forces is still polarized, and the endurance test of the China Automobile Research Institute can see that there is a certain gap between the new forces of car-making and the traditional car companies in some of the underlying technologies, and the new car-making forces have to play a good job in terms of basic skills if they want to completely obtain the recognition of consumers, step by step relying on the accumulation of technology, rather than just relying on the mouth to compete with traditional car companies such as BBA.
