　　Battery technology restricts the development of electric vehicle industry

　　In terms of technology, Zhang Guobao said that finding an energy source other than gasoline, diesel, and liquid fuel has always been a direction that the automotive industry is looking for. But for so many years, there has been no major breakthrough in battery technology. The battery accounts for a very large amount of weight in the entire electric vehicle, accounting for at least one-third of the entire weight of the vehicle. The battery weighs 600 kilograms, and it has to be charged continuously. The running distance is only about a hundred kilometers, and the charging time is quite long. Although some measures can be taken to shorten the charging time, sometimes it takes several hours to charge. , these all affect the use of electric vehicles.

　　In terms of cost, Zhang Guobao said that although there are subsidies in various places, after subsidies are available, customers who purchase electric vehicles still have to weigh them. First, is it convenient to use and can it be charged at any time? In addition, is it convenient in all aspects of maintenance? Although charging stations are now being built in various cities, consumers still wonder whether it is possible to charge them wherever they drive. In addition, data shows that the cost of operation is still low, because it costs money to buy gasoline, the price of gasoline is rising, and electricity must be used instead of gasoline. The operation may still be cheaper, but the initial investment cost, including its after-sales service, these aspects The problem still exists.

　　At the same time, Zhang Guobao emphasized that when a new thing appears, it will always have its imperfections and imperfections. But human beings are always making progress in solving these problems. Therefore, although electric vehicles have encountered some problems, they have also made great progress. On the one hand, the driving distance of electric vehicles after one charge is getting longer. Sometimes they can run more than 100 kilometers on one charge. Now they can run 260 miles on one charge and can run 400 kilometers. The kilometers they can run on one tank of gas are about the same. , the top speed reaches 200 kilometers per hour, which is not much different from a gasoline car. On the other hand, charging technology is also constantly improving, shortening charging time.

　　"These aspects of electric vehicles are gradually developing towards practical use. Therefore, we should affirm that it pays attention to it. Who can guarantee that the price of gasoline will not increase in the future?" Zhang Guobao said.
