The more durable the battery of an electric vehicle, is it really beneficial to the development of electric vehicles?

A few days ago, an overseas company called Geotab released a piece of data, which is a survey data on how electric vehicle batteries degrade over time. Judging from the number of samples, the company has collected data on the use of nearly 6,000 pure electric vehicles in the world, which is convincing. And in the end, they came to the conclusion that pure electric vehicles will attenuate 2.3% of their electricity annually. This conclusion clearly points out that the service life of the battery will be clearly greater than the service life of the vehicle itself. According to the second-hand car transaction data released by the my country Automobile Dealers Association in 2018, there are more and more second-hand cars with the age of less than 6 years, which also means that the frequency of car replacement by Chinese people is accelerating. Many people will be replaced after 6 years. Based on this premise, let's calculate the battery life and vehicle life of pure electric vehicles. Assuming that the decay of the battery is 2.3% per year and 13.8% after 6 years, the remaining capacity is 86.2% of the initial capacity. According to the data, the battery capacity of the 2015 Tesla Model S is attenuated by an average of 2.3% per year. For this electric vehicle with a battery life of up to 528km, the annual loss is 2.3%. After 6 years, the remaining comprehensive battery life is about 455km. . Taking the current pure electric vehicles on the market as an example, most of them can achieve a battery life of more than 400km. From the current development trend, 500km battery life will soon become standard for many electric vehicles. If it is a rough calculation, this means that the endurance attenuation per year is only 10km, which is completely within the acceptable range. It can be seen that if the data is true, the battery life of current electric vehicles on the market is sufficient to meet the needs of car owners. If you think this is not convincing enough, then I might as well give a few more examples. The world’s first mass-produced electric car was the GM EV1 of the last century. It has been more than 20 years ago, but it can still be seen on the road; the GM volt1 and Nissan leaf between 2010 and 2011 have not There has been a record of large-scale battery replacement in the United States; since 2010, Shenzhen BYD’s taxi operation has never seen a record of large-scale battery replacement. Various examples show that, regardless of whether it is used abroad or domestically, whether it is used for a long time or at high intensity, the attenuation of the battery is not as terrible as the general public imagined. So back to the beginning of the article, can the excessive pursuit of battery durability really benefit the development of new energy vehicles? Here, I introduce a concept plan to scrap. In the early and mid-twentieth century, this design concept was proposed and is still used today, the most famous of which is the Sun God Project. Everyone knows that light bulbs must be replaced after a certain cycle, but did you know that in a fire station 115 years ago, there was an ordinary light bulb that has been on until today? This is undoubtedly inconsistent with most of us. A light bulb with such a long life can be made in more than 100 years. Why can't it be done today with more advanced technology? This is planned scrapping, which refers to the artificial manipulation of manufacturers in the process of designing and manufacturing goods to limit the service life of the product. In today's various industries, planned scrapping exists, and the most obvious one is a fruit mobile phone. In the automotive category, planned scrapping has always existed. To give a simple example, car scrap is actually a simple understanding of planned scrap. Through paid scrapping, the car will be scrapped earlier, so as to achieve the replacement of the car. From the consumer's point of view, this approach is undoubtedly shameful. But starting from our needs, do we really want such a durable product? Also take mobile phones as an example. Once Nokia was very durable, right? In terms of quality, it can even block bullets. The durability is obvious. But why will Nokia be eliminated, and the rise of Apple phones that are inferior to its quality and battery life? To put it bluntly, the times are developing, and diversity is gradually phasing out durability. Conversely, the reduction in durability will also encourage manufacturers to work harder on research and development and launch newer and more diverse products to cater to consumers. The plan to scrap the analysis is here, let's go back and talk about electric vehicles. The battery life of today is higher than that of electric vehicles. In other words, the durability of the battery is high enough. If we continue to emphasize battery life too much, will it really benefit the development of new energy? I think the answer is not definite. Today's automobile development trend is the new four modernizations. Electricity is the foundation and cornerstone, but it is by no means advanced and final. Intelligentization is. The same is Tesla. In addition to launching models with higher battery life to meet the needs of the market, it will also get involved in planning to scrap. But different from the practice of limiting product life, Tesla's approach is more business-minded, re-solving the problem by planning to recycle old batteries for household electricity storage. Compared with traditional planned scrapping, this approach is more circular and more sustainable. At the same time, this approach can also allow consumers to gradually turn their attention from the endurance to the vehicle itself, and evaluate the vehicle more comprehensively from the perspective of quality. Of course, Tesla’s approach is similar to that of many traditional luxury brands, and is therefore different from most joint venture brands and independent brands. This is largely due to different consumer perceptions caused by the value of the vehicle itself. Just like a car owner who buys a Rolls-Royce, it has never considered the durability of the vehicle, because from the moment it buys the car, the car has been endowed with heritage, and its durability should be Summarized in its own value, this is also a tonality of luxury brands.
