Abstract

The electric vehicle charging station should be allocated based on traffic density, geographical distribution and other factors, and Voronoi diagram is adopted to set the service area of charging station. In combination with the actual situation of site selection of electric vehicle charging station, the comprehensive benefits index system is established. There are numerous factors influencing the site selection, among which there are uncertainty and fuzziness. The comprehensive evaluation method based on the fuzzy analysis and Analytical Hierarchy Process (AHP) is used to evaluate the comprehensive benefits in the site selection of electric vehicle charging stations, with the consultation of experts. This paper contributes to the best selection of comprehensive benefits and provides the reference for the decision-making of building the electric vehicle charging station. Actual examples show that the method proposed is effective.

Highlights

  • With the growing problem of global fossil energy crisis and environmental degradation, all countries turn their attention to the development and application of new energy currently so that exploration and research of largescale electric vehicles has become a hot spot

  • The comprehensive evaluation method based on the fuzzy analysis and Analytical Hierarchy Process (AHP) is used to evaluate the comprehensive benefits in the site selection of electric vehicle charging stations, with the consultation of experts

  • This paper combines the advantages of these two methods, determines the weights of the sub-targets and indexes by AHP, evaluates the comprehensive benefits of the site selection of electric vehicle charging station by Fuzzy- AHP and provides the reference for the optimal decision-making of the site selection [4, 5]

Summary

Introduction

With the growing problem of global fossil energy crisis and environmental degradation, all countries turn their attention to the development and application of new energy currently so that exploration and research of largescale electric vehicles has become a hot spot. Markets around the world have a greater demand for family cars with economic development and the improvement of people’s income levels, which has certain positive significance in improving residents' travel modes and the development of the automobile industry, and has a negative impact on energy security and environmental protection. Construction of electric vehicle charging station is a prerequisite for the popularity of electric vehicles while improving the efficiency of energy supply network is one of the necessary conditions for electric vehicles widely used [1, 2]
