In the past month, the international crude oil price has been soaring, and even has come to the price of 130 US dollars a barrel, which has also made the domestic oil price embark on the nine yuan era, many oil car owners have shouted that they can't afford to drive, and even called out "adding a tank of oil is a bicycle" "four tanks of oil can buy an electric car" to ridicule the high price of oil, at this time new energy vehicles into the field of vision of many people.
The rise in oil prices is bound to be conducive to the sales of new energy sources. According to Electrork on March 10, due to the current soaring international oil prices, more and more consumers are considering buying new energy vehicles, among which Tesla, the world's leading new energy vehicle manufacturer, has seen a significant increase in orders in the United States this week.
Domestic is no exception, but there are still a large number of people who want to buy new energy vehicles but are afraid to welcome back an "electric daddy", after all, the endurance diabetes in the low temperature environment of pure trams is really rendered some terrible, and even some people convey the feeling that pure trams can't drive out of the house in winter. Perhaps in order to let everyone face the endurance of pure electric vehicles in winter, the Consumer Associations of Beijing, Tianjin and Hebei Province organized a comparative test of the low-temperature mileage of electric vehicles, which is also a more official and authoritative experiment in the domestic low-temperature endurance test of electric vehicles.
It is understood that the comparative test vehicles are all sent by vehicle companies, with a total of 10 sample cars and 10 models. Involved brands are Polar Fox (ARCFOX), BYD, Xiaopeng, Roewe, Weilai, Changan, etc., including new forces and veteran car companies, the coverage is more comprehensive, the selected models are also relatively hot in the market, including BYD Han, Geometry C, Xiaopeng P5 and so on.
According to the information released by the Beijing-Tianjin-Hebei Consumer Association, the test process is more rigorous. First of all, they will fully charge all models at room temperature environment 20 °C ~ 30 °C, stand at -10 °C ± 2 °C ambient temperature for 12 hours, and carry out mileage tests in accordance with the relevant requirements of GB/T 18386-2017 "Electric Vehicle Energy Consumption Rate and Mileage Test Method", and turn on the heating throughout the process.
Of course, the results of the experiment can be seen in the table. Overall, it seems that pure trams do have a lot of attenuation at low temperatures, the absolute value is about 150km, but because the experimental results failed to mark the corresponding attenuation ratio, from the absolute value, the polar fox relied on the super battery capacity to get the championship, BYD Han although lithium iron phosphate, but the performance is still good.
The Travel Bureau recalculated the attenuation ratio for each model, and the data are as follows: Polar Fox attenuation ratio of 28%, BYD Han 33%, Geometry C36%, Sihao IC537%, Xiaopeng P539%, Euler Good Cat 33%, Roewe MARVEL R42%, Eian S38%, NIO ES638, Changan Yidong EV 39%.
It can be seen that the overall attenuation amplitude is more than 30%, and the attenuation ratio of models with high absolute values like BYD's Han and Polar Fox Alpha S is also well controlled, and the worst models are Roewe's MARVEL R and Changan Yidong EV.
It is worth noting that the Weilai ES6 is the only model with a high battery capacity, but the final endurance performance and decay value are ranked at the bottom, which may be related to the weight of the Weilai ES6, but it can also be seen that the resistance of The Weilai battery to low temperatures is indeed not strong.
For friends who want to buy a tram now, the endurance of pure electricity in winter does have a certain discount, but it is not to the point of not being able to go out, and the discount rate is basically about 60%. Of course, in the case of a certain choice, models with larger battery capacity will often have better performance in winter, which is not only reflected in the maximum endurance, but also has considerable advantages in winter attenuation, and everyone can also be used as an important reference when buying a car.
