The sequential construction research of regional public electric vehicle charging facilities based on data-driven analysis—Empirical analysis of Shanxi Province

The contradictions of charging facilities supply and demand are intensified in China, the surplus and shortages of charging facilities simultaneously existing, and the utilization of charging facilities significantly polarized. To solve the problems, the sequential construction research method of regional public electric vehicle (EV) charging facilities is proposed based on the demand differences of charging facilities in cities and the utilization differences of charging stations in the same city. According to the actual charging transactions big data of Shanxi, the construction sequence of regional public charging facilities has been studied, which verified the scientificity and effectiveness of the proposed method. The results show that the charging facilities demand of 11 cities in Shanxi can be divided into 4 types, Linfen and Lvliang having the highest demand for charging facilities in the short term and long term; in the same city, the utilization of charging stations in residential areas is the highest, and the utilization of charging stations in working areas is the lowest; so, the charging facilities construction should focus on residential areas in Linfen and Lvliang. The proposed method is contributed to realizing accurate construction of charging facilities, which helps to guide the charging facilities planning of the government and the investment of charging facility investors.
