How do new energy vehicles have strong endurance?

Every commentator Wang Zifei

This year’s National Day holiday conducted the strongest “stress test” in the history of new energy vehicles, which exposed many problems that consumers encounter in daily use of cars. . Among them, related issues such as difficulty in charging new energy vehicles and long journey times frequently become hot topics.

It can be seen that while new energy vehicles have been criticized, they are also very popular in the market. Since the beginning of this year, 1.87 million new energy vehicles have been registered in China, which is approximately 1.7 times that of 2020. In September alone, the delivery volume of BYD, NIO, Xpeng and other car companies has exceeded 10,000 vehicles, showing a high growth trend.

There is no doubt that new energy vehicles are already at the forefront. On the one hand, we should see the rapidly growing demand for new energy vehicles; on the other hand, as more and more users choose new energy vehicles, we should also see more problems that need to be solved and optimized, and provide new solutions. .

During the National Day, the topic of difficulty in charging new energy vehicles remains high because it hits the real pain point of insufficient battery life of new energy vehicles. From the perspective of daily commuting, the battery life of new energy vehicles can basically meet the needs, but when traveling on weekends and holidays, the weak battery life will be exposed. The number of people traveling during National Day this year exceeded 500 million, which shows the extent of highway congestion. As the driving load increases, the actual range will decrease.

At present, there are two main solutions to improve the endurance of new energy: one is to increase the energy density of the battery, that is, break through technology and increase the mileage; the other is to improve the convenience of charging, such as increasing the charging speed. , increase the number of charging piles.

Since this year, although many car companies have successively launched so-called "power batteries with a range of more than 1,000km", from an application perspective, "power batteries with a range of more than 1,000km" seems to be just a myth. , the user’s actual endurance is still within the range of 300~500km.

Of course, the author does not deny that long battery life is the future development direction of new energy vehicles, but until battery technology has not fundamentally changed, do not blindly pursue long battery life.

From a safety perspective, the higher the battery energy density, the higher the battery activity, resulting in unstable batteries and potential safety hazards. According to reports, many new energy vehicle spontaneous combustion accidents are caused by battery problems. In addition, with current technology, the weight of the battery will increase, which will also affect battery life. Excessive promotion of long battery life will increase vehicle weight and usage costs, and increase more energy consumption.

In the author’s opinion, in order to improve the endurance of new energy vehicles, it is best to improve the convenience of charging.

First of all, charging facilities must be reasonably arranged. As of the end of September, the number of new energy vehicles in my country reached 6.78 million, and the total number of charging infrastructure nationwide was 2.105 million. Both quantity and growth rate have been significantly improved, but there is still huge room for optimization in the distribution structure.

Secondly, we must develop fast charging technology. Fast charging is currently the mainstream power supply method for new energy vehicles. On the basis of safety, it is the future trend to open up the charging pile gap between car companies and realize the most enjoyable charging. Furthermore, it is necessary to combine smart technology to provide convenient and economical charging solutions, promote a virtuous cycle of "pile-grid-vehicle", and reduce users' time costs.

In order for new energy vehicles to go further, companies should not over-hype battery innovation and greatly improve battery life, but should be down-to-earth based on technology research and development, taking into account product safety, quality and battery life. Users should also self-regulate their "range anxiety" and choose vehicles with appropriate price, range, and energy consumption based on actual needs. In this process, we also look forward to more and better policies and supervision. Only in this way can the new energy automobile industry develop healthily and sustainably.
