Everyone is familiar with new energy vehicles. In the future, the mainstream direction of automobile development, new energy can be said to have become a hot-selling car. Although the development has been faster, compared with traditional automobiles and various types of cars and follow-up services, since new energy vehicles start relatively late, there are still some problems that need to be solved for new energy electric vehicles?

There are some urgent problems that new energy vehicles currently need to be solved. New energy vehicles are different from traditional fuel vehicles. Traditional cars can basically not have many problems in powertrains, and basically only need to be improved. However, the main core technologies of new energy vehicles are batteries, motors, and electronic controls. At present, battery technology is its bottleneck. The battery's range cannot reach a certain range, followed by the battery's energy density, which still cannot meet the standards of fossil fuels.

And due to the characteristics of lithium batteries, the range is insufficient under low temperature conditions. Secondly, in terms of charging efficiency of electric vehicles, the difference between the fuel oil and traditional fuel vehicles. Although the battery of some models can now supply a range of about four or five hundred kilometers, the charging speed in a short time is an important problem at present.

The battery cell is high voltage, and the current technology fast charging will take half an hour to fully charge the battery. In an emergency, time will be delayed, but with the continuous progress of technology, these will be solved within a certain period of time. Finally, it has to be said that my country's new energy vehicle industry is developing very fast, ranking first in the world in terms of growth rate and production and sales. However, as an emerging industry, it also faces many challenges, so it needs to be further strengthened in the technological development and management system.
