Recently, the State Grid announced that it will further accelerate the construction of charging facilities across the country, and achieve electric vehicle charging network coverage of suburban counties across the country by 2020! The rapid charging of electric vehicles in suburban areas and counties within a radius of no more than 5 kilometers, 3 kilometers around the urban area, and 1 kilometers in the urban area is basically realized. At the same time, we also hope to use the smart car networking platform and the sharing economy model to gather more social forces and more social capital to participate in the investment and construction of charging and replacing facilities. In addition, according to the planning of the National Development and Reform Commission, the total investment in charging equipment in the next five years exceeds 60 billion yuan. "A sound ecological environment is the fairest public good and the most inclusive welfare for the people." The promotion of new energy vehicles is not only in line with the general situation and trend of ecological civilization construction that the country is actively advocating, but also the practical needs of urban environmental protection and people's health.
