Abstract: [Introduction] In response to the call of national energy-saving and environmental protection, and to promote the promotion and application of new energy vehicles, local governments have steadily increased policy support, which has strongly promoted the development of charging infrastructure for electric vehicles. With the increasing number of large industrial parks in China, the rational layout of charging infrastructure for electric vehicles in advance will promote the power supply in the parks. The rapid development of electric vehicles is of great significance. [Method] The charging characteristics and driving characteristics of electric vehicles were analyzed, and then a comprehensive optimal model of charging station construction cost and charging cost was established. Considering the grid layout method of charging facilities based on Geographic Information System, the Pareto algorithm was adopted to improve the optimization of charging facilities. Secondly, according to different charging time and charging cost, the investment payback period of electric vehicle charging facilities was compared and analyzed. [Result] The results show that the optimal plan of regional charging facilities layout and construction is obtained, which can improve the utilization efficiency of charging facilities and equipment, improve the investment efficiency, and enhance charging facilities. [Conclusion] The feasibility and validity of this planning scheme are demonstrated by comparing and analyzing the case of charging station planning in an industrial park in the Pearl River Delta.
