Locating Multiple Size And Multiple Type Of Charging Station For Battery Electricity Vehicles

In recent years,due to the aggravation of environmental problems and the public's increasing attention to environmental protection,many companies are spending more and more money on research and development of electric vehicles,and the government has also adopted relevant policies to promote the rapid development of battery electric vehicles.Battery life and charging of electric vehicles is one of the most urgent problems to be solved,which is also one of the problems studied by many scholars,and most of them still prefer to use charging stations to charge electric vehicles wired.Therefore,location has become one of the main research directions for the construction of BEV charging stations.Solving the problem of how and where to build a charging station can not only effectively reduce the construction cost for the government,but also can make it convenient for users and further promote the use of electric cars in people's life.Secondly,due to the constant maturity of the current rapid charging technology,users have different charging demands in different scenarios,and the cost difference between the construction of conventional charging stations and rapid charging stations is relatively large.We considered the location problem of charging stations of different types of pure electric vehicles(mainly measured by charging rate)and different sizes(mainly measured by the number of charging piles contained in charging stations)in this study.Based on our research,we consider the charging demands of different users and different scenarios of the same user,and based on these we decide which type and scale of charging stations should be built.It not only helps the government to reduce the construction cost and save the budget,but also enables users to find the charging station that meets their needs as soon as possible in the driving process of pure electric vehicles.Therefore,it can also improve the service level of users and further promote the development of electric vehicles.Firstly,this paper summarizes the development status of BEV charging stations at home and abroad and the research status of charging station selection.The main modes of energy supply of pure electric vehicles are described.The principles of site selection and layout of charging stations for battery electric vehicles are introduced,which provide a theoretical basis for subsequent studies.Through the foreshadowing of the first two chapters,in the third chapter,we firstly study and consider the site selection of charging stations of battery electric vehicles with different scales.The model is based on certain assumptions and the sensitivity analysis is carried out on the Nguyen-Dupius network and the Sioux-Fall network.In chapter 4,location problem of charging stations of different types and sizes is considered.In order to verify the effectiveness of the model,the above two networks are used for solution and analysis.Finally,we introduce the actual network,set up the network diagram with Zhangjiakou city as the background,and use the model to solve and analyze.The results also verify the feasibility and effectiveness of our model.
