Tesla's hidden doorknob froze. What else needs to be improved in electric vehicles?

First, rumors and prejudices from the Internet. At present, the prejudice against new energy vehicles on the Internet has not stopped. A little bit of negative news related to new energy vehicles can be infinitely exaggerated and spread by people with a heart.

Tesla's hidden door handle was frozen, which was indeed technically imperfect and brought trouble to the owner. However, some rumors are really excessive: the power battery is clearly guaranteed for 8 years or10.2 million kilometers, but the service life of lead-acid batteries is only three to five years; It is clear that only dozens of new energy vehicles catch fire in the world every year, but it is rumored that new energy vehicles frequently spontaneously ignite. These irresponsible rumors are flooding the network, which is not conducive to people's objective understanding of new energy vehicles, and also greatly hinders the growth and development of new energy vehicles.

Second, the battery problem of electric vehicles The battery technology of electric vehicles is still immature. First, new energy vehicles continue to drive seasonally, and the mileage in different seasons is shortened, and the speed mileage is shortened. The biggest problem with the emergence of new energy vehicles is the short driving range. At present, the driving range of mainstream new energy vehicles can reach more than 400 kilometers, but the problems of seasonal driving range shortening and speed driving range shortening still exist. On the one hand, it affects consumers' experience, on the other hand, it also affects the development height of new energy vehicles.

Secondly, the slow charging speed has always been a major pain point for electric vehicles. At present, even if DC fast charging is used in electric vehicles, it takes about 1 hour for new energy vehicles to be fully charged, and only 5 minutes for gasoline vehicles to refuel. The high battery price directly affects the whole vehicle price of new energy vehicles. Secondly, the safety of batteries is also a public concern. The news about the problems in the power battery pack of new energy vehicles is also endless. In the final analysis, the emergence of the problem is related to the characteristics of the power battery pack of new energy vehicles. After all, the current power battery technology can not achieve the unity of large capacity and stability, which naturally makes new energy vehicles have hidden dangers in the safety of power batteries. ?

Third, the problem of charging facilities Although the construction of charging piles in China developed rapidly last year, problems such as a small number, unreasonable layout, and the failure of pile construction enterprises to achieve interconnection are still outstanding, and the problem of inconvenient charging of new energy vehicles still exists. If the charging problem is not solved, the development of electric vehicles will still be limited by the region.
