Abstract: Abstract: As an effective way to solve energy shortage and environmental pollution, electric vehicle has become a research hotspot. The development of electric vehicle is restricted by factors such as unreasonable distribution of charging infrastructure and poor operation and maintenance. This paper analyzes the influencing factors of charging pile construction and uses the queuing theory model to establish a charging station operator's initial investment cost and later operation and maintenance cost. The charging pile configuration model whose objective function is to minimize the charging waiting time cost of the charging user, study the configuration problem of the number of charging piles in the charging station under the mode of known charging demand. Taking a business district in Guiyang as an example, the study founds that when 11 charging posts were installed, the combined costs of charging users and operators were the lowest, and the utilization rate of charging posts was the best, the analysis of the example verifies the feasibility of the model.
