Statistics show that the 2017 new-energy vehicle ownership, public charging pile number, car pile ratio compared with before 2012 decreased, but the rate of construction of charging piles is not keeping up with the manufacture of new-energy vehicles.
The growth rate of private charging piles is higher than the sales of NEVs, with an average annual growth rate of 109 %, and the vehicle-pile ratio decreases year by year, and the vehicle-pile ratio of private charging piles is expected to be 2.5:1 in 2025.
China’s ratio of new-energy vehicles to charging piles still does not meet the requirements of the development guide. Accelerating the planning and implementation of the reasonable construction of charging piles is the cornerstone of further development.
The study then transforms time-series data of the EV charging piles into a complex network by applying a visibility graph, uses several clustering methods to categorize different provinces, and predicts the future development of the network of EV charging piles in China.
According to the forecast results, there is a gap between the average growth rate of public charging piles and new energy vehicle sales, which leads to the vehicle-pile ratio of public charging piles will gradually climb from the lowest point of 5.7:1 in 2021 and is expected to reach 10.2:1 in 2025.
The eccentricity of the network nodes of charging piles is mainly around 3 or 4, and the distribution of all charging piles is especially concentrated. This reflects the rapid manufacture of new-energy vehicles, whereas the rate of manufacture of charging piles is relatively stable.
