If electric cars can solve the problem of battery life, the public should prefer electric cars. Over the years, the new energy industry has become the key support object of the state, and domestic new energy vehicles have also developed rapidly. Both new forces and established car companies have come up with their own electric car products and achieved good results. A few days ago, the director of the National Energy Department said that with the development of electric vehicle technology in the future, cars can not only undertake the role of transportation, but also undertake the role of energy storage. Cars can be charged when the power consumption is low and discharged when the power consumption is high, so that the power of cars can be stored.

In fact, some people have been thinking about this problem for a long time, but considering that the charging and discharging of electric vehicles is still a challenge, many people are reluctant to discharge into the power grid system after charging. But there is a model that can solve this problem, such as the power station provided by Weilai Automobile. Someone has already done so. Some Weilai car owners take advantage of low electricity consumption at night to fully charge their cars at low prices. The next day, they drove to a power station and replaced the battery, so that the low-priced electricity in the original battery was replaced by a power station, so that they could earn more than ten yuan each time.

If the power exchange station can be popularized on a large scale, all the cars driving on the road will become energy storage equipment. If the power grid is short of electricity, it can increase the electricity price to attract car owners to change electricity, but it can supply power to the power grid.

Huang Xuenong, director of the Electric Power Department of the National Energy Administration, said that charging electric vehicles seems to be a power supply task of the power system. However, through technical development, including taking economic measures, electric vehicles can completely improve the system capacity. When the electric vehicle is in a trough, the system charges it; During the peak period, let the electric car discharge the system. Electric vehicles may become energy storage devices in power systems. If there are thousands of large electric vehicles, it will be a very favorable factor for the system. Therefore, it is necessary to speed up the construction of charging and replacing infrastructure, on the one hand to promote the development of new energy vehicles, on the other hand to promote the construction of new power systems.
