Don't dare to turn on the warm air and overtake at high speed. The "old and weak" electric car owners have too many troubles in winter.

With the vigorous promotion of "environmental protection and green travel" and the implementation of policies related to new energy vehicles, domestic consumers are paying more and more attention to new energy vehicles, and their acceptance is also increasing. In just a few years, the role of electric vehicles has changed from "exotic, high-end and toy" to "ordinary, people-friendly and easy to use" means of transportation. I believe that in the streets of your city, there have been many green electric cars in the endless traffic.

compared with traditional fuel vehicles, pure electric vehicles have the advantages of lower cost and no traffic restrictions, but at present, pure electric vehicles also have many shortcomings, such as cruising range anxiety, slow charging and difficult charging. And now it is winter, and the temperature drops suddenly, which has a great influence on the car experience of pure electric car owners. Many electric car owners have given us feedback on how bad their winter car experience is. To solve this problem, we interviewed some electric car owners in Chengdu and its surrounding cities.

electric bus driver (Yinlong New Energy): If you dare not turn on the warm air in winter, it will be difficult to complete the task.

Fixed lines and special purposes are the best car scenes for pure electric vehicles at present, which is also an important reason for vigorously promoting bus electrification in China. Chengdu is one of the first cities in China to promote the electrification of buses. No matter the main city or the districts, cities and counties, most buses have been replaced by electric vehicles. In view of this, we first interviewed the drivers of pure electric buses.

after taking a bus on a line at random, we learned from the communication with the driver that the bus he is currently driving is a model of Yinlong New Energy. Usually, he can run more than 2 kilometers with full charge. The route he drives is about 8 kilometers one way, and he has to drive nine times a day. So, the mileage he drives every day is about 144km kilometers. In other words, under normal circumstances, the battery will not be exhausted after completion every day.

but in winter, if you turn on the warm air, you need to recharge if you can't run nine times. That is to say, in the absence of battery attenuation (Yinlong New Energy's bus was replaced in July this year), after the warm air is turned on, the endurance attenuation range is at least 4%. Obviously, such endurance performance is difficult to satisfy the drivers coming from the fuel bus era. Moreover, the driver also stressed that in the past, because the engine was in the front, the fuel truck would generate heat when running, and the cab was very warm even in winter. But now, facing the cold motor and floor, only by wearing more clothes can we keep out the cold.

owner of Chery eQ1: I dare not overtake and don't turn on the air conditioner. After buying a car, I have become Buddhist.

Unlike Chengdu, the infrastructure construction of charging piles can't keep up because the penetration rate of electric vehicles in surrounding cities and counties is not high enough, or many charging piles in remote places have problems such as idle charging and power failure. Many car owners who live in the north of the city need to drive several kilometers to the south of the city to charge if they want to charge quickly. Who is this? Mr. A, the owner of Chery eQ1, is one of them.

Mr. A's little ant was bought in 219, and it has been driving for about a year now. It is usually used for walking in the city, and the use environment is basically urban roads. At first, Mr. A praised his car constantly, such as: cheap price and convenient parking …, but when we talked about the decline of battery life in winter, Mr. A began to smile: "When I used to drive a fuel car, my personality was still very grumpy. If someone overtook me (not as good as my car, not as expensive as my car), I would not hesitate to overtake the floor oil. But now, after driving this electric car, in those days, Especially in winter, when you step on the accelerator, you will worry that the power failure will be particularly fast. Can you squat halfway later? "

before we even asked Mr. a if he dared to turn on the air conditioner in winter, Mr. a followed the topic of overtaking and talked about turning on the warm air. "If the warm wind is turned on in winter, it is estimated that a car with a standard endurance of 31km can only drive for more than 1 kilometers, so I have to close the window when driving and bring a scarf and hat to keep warm."

owner of Beiqi new energy EU26: It is faster to turn on the warm air in winter, and it takes longer to charge.

During the interview that day, we saw that most electric vehicle models are relatively new, and among the domestic models, the oldest one should be this Beiqi new energy EU26. Mr. B said that this car has been driving for nearly three years. At the beginning, although air conditioning was usually turned on in summer, the actual cruising range at this time was smaller than the advertised cruising range. When used in winter, although the cruising range will be more obviously reduced after the heating and air conditioning is turned on than when the cold air is turned on in summer, it can still run about 18km as a whole.

but now the situation is different. after several years of use, Mr. b obviously feels that this car has entered the "old age stage". Don't say that the warm wind is turned on in winter, even when driving, it will keep driving at a constant speed of 7 to 8 yards, otherwise the car may not run as far as the electric bicycle. In addition, Mr. B also complained to us about the slow charging of electric vehicles in winter. "Small counties were originally filled with less piles, and many of them were occupied by electric trucks running logistics. It was finally charged, and the charging time was obviously longer in winter, which made me very upset."

to sum up briefly, according to our investigation, the impact on the cruising range of electric vehicles after air conditioning is turned on in winter is still great. The cause of this problem is that PTC (Thermistor) is widely used in the heating devices of electric vehicles at present, and its power can reach 2-3kW. Such a large power consumption is undoubtedly extremely fatal to the battery power that would otherwise be attenuated. This is also an important reason why many electric car owners dare not turn on the warm air in winter. It can be seen that most of the models surveyed in this issue are old or cheaper electric vehicles. In the next article, we will report the new electric vehicle with advanced technology, so stay tuned!
