"In 20 17 years, the construction of public charging piles is also growing steadily." Liu Baohua said that by the end of last year, China had built 265,438+million public charging piles, ranking first in the world. Among them, 86,000 AC piles, 6. 1.000 DC piles and 66,000 AC -DC integrated piles. The construction of intercity express charging stations has been accelerated, and more than 400 charging stations 1.400 have been built, involving 19 provinces and cities and serving 3 1.000 kilometers of expressways.
However, in Miao Wei's view, the national car-to-pile ratio of 3.5 ∶/kloc-0 ∶ still can't meet consumers' demand for charging. "With the continuous growth of the number of new energy vehicles, the problem of insufficient structural supply of charging infrastructure has become increasingly prominent, and the overall scale is still lagging behind." Miao Wei, an expert, said that China plans to build about 500,000 public charging piles in 2020, but compared with the planned annual production and sales of 2 million and 5 million vehicles in 2020, the number of charging piles still does not match, and the ratio of vehicles to piles even tends to deteriorate. In addition, the layout of charging facilities in China is not reasonable enough, the utilization rate of public charging piles is insufficient 15%, a sustainable business development model has not yet been formed, and there is still a two-way contradiction between the profitability of operating enterprises and the high charging price reflected by consumers.
