Research On The Site Selection Of Electric Vehicle Charging Station Based On Fuzzy Analytic Hierarchy Process

Electric vehicle replacing oil with electricity has many advantages,such as high energy utilization efficiency,less emissions,little noise,simple structure and so on.It is one of the most important ways to solve the current tense energy and environmental problems.In the last two years,electric vehicles have been developed rapidly.Such as,Tesla,BYD,BMW and JAC and other new energy electric vehicles,have been widely used.The future direction of the automobile industry is the new energy vehicles.However,the main factors that restrict the development of electric vehicles are difficult charging,long charging time and short mileage.Therefore,we must build a convenient,fast,economical and efficient charging system to ensure the daily charging of electric vehicles.At the same time,a perfect charging system is also a prerequisite for the rapid development of the electric vehicle industry.A series of studies have been carried out in this paper for the location of electric vehicle charging stations.First,through reading a large number of relevant documents at home and abroad,drawing on the relevant theories and methods,this article makes innovations and extensions based on previous studies,and puts forward the research content of this paper is to evaluate the site selection of electric vehicle charging station based on Fuzzy Analytic Hierarchy Process(FAHP).Secondly,the main factors affecting the location of electric vehicle charging station are analyzed.To determine the influence factors of the four aspects of traffic convenience,operating economy and safety of power grid,regional economic development and so on.Based on FAHP,the evaluation index system of location of electric vehicle charging station was established,and the weight of each index was determined.Finally,five charging stations are selected from the built charging stations in Jiaozuo as the research object.Through expert questionnaire survey method,we use the evaluation index system of electric vehicle charging station established in this paper to make a comprehensive evaluation of five selected charging stations,and the comprehensive evaluation score of the charging station is compared with the actual situation of the charging station.The effectiveness of the evaluation index system established in this paper is proved by practice,and the practicability of FAHP in location evaluation of electric vehicle charging station is verified.
