Although pure electric vehicles are a major trend in recent years, due to the limitations of battery technology and safety considerations, there has been a lot of room for improvement in battery life and charging, otherwise it will be difficult to form an advantage over fuel vehicles. These problems are not a certain brand or a certain model, but the whole industry.
However, as battery technology has achieved certain results, during this period many car companies have gathered together to announce their own 1,000 km battery life technology. But under this trend, someone has a different voice, and that is the CEO of Weilai. Weilai's CEO's answer to this question some time ago caused an uproar. Li Bin of Weilai Automobile responded to the problem of 1,000 kilometers of cruising range: It is not that the battery is not good, but the main body of the car is not good.
For car owners, one of the major factors affecting their purchase of new energy vehicles is the battery life. After all, it is troublesome to charge once. If the battery life is short, it means that you have to charge frequently. If the battery life is longer, let the car be used Frequent car owners can charge it once a week, which is ideal. If a car company can charge car owners only once every half a month, I believe they will be welcomed by many car friends.
In addition, if the battery life is short, causing the owner to charge frequently, it will also cause the battery to decay faster. A battery that has been charged and discharged 1000 times will definitely attenuate more than a battery that has been charged and discharged 100 times. Perhaps a battery that has been charged and discharged 100 times will still have 80% of the new battery after it is fully charged, while a battery that has been charged and discharged 1000 times will be fully charged. 40% of the new battery life is left. Therefore, in our ordinary people's thinking, the longer the battery life, the better, the longer the battery life, the less the number of recharges, the slower the battery attenuation, these are very simple principles. And many car companies get together to announce their 1,000-kilometer battery life, in fact, from this aspect, it broadens the hearts of car owners, no problem at all.
and Weilai CEO Li Bin publicly stated that it is not necessary to do 1,000 kilometers. He said that when a person drives continuously to 1,000 kilometers, the biggest impact on him is not the endurance, but the physical strength. Can't keep up. Therefore, instead of putting the direction of research and development to the 1,000 km mark,It is better to study how to make the battery life attenuate less in winter and charge faster. These two problems are solved, even if there is no 1,000 kilometers of battery life.
In fact, this statement seems to be very reasonable at first glance, because Li Bin said it was not very convincing. We must know that the Weilai ET7 released a few days ago has a 150KW version with a battery life of 1,000 kilometers, and Weilai is still the first to release it. That is to say, Li Bin first released a 1,000-kilometer battery life, flaunting his own advantages, and seeing other car companies release, and said that this technology is unnecessary, and perhaps it is still a bit unreasonable before and after.
In fact, to overcome the problems of battery attenuation and charging speed in winter, it does not conflict with the problems of battery life. I personally think that it should be placed in the direction of new materials. After all, even if the problem of battery attenuation in winter can be improved, even if the charging speed becomes faster, car owners still don’t like to park their car for a long time. Some car owners don’t even have charging piles and can only go outside to charge. The extra time cost of buying an electric car can be saved for car owners. What do you think?
