Research On The Layout Planning Of Electric Vehicle Charging Station In The City

Facing enormous pressure energy and the environment, people continue to seek a clean alternative fuel, in order to improve the deteriorating status of the traffic emissions, electric vehicles become governments and car manufacturers focus. Electric vehicles are actively used in city traffic in many cities at home and abroad. Construction and development of electric car power supply system is one of the key factors which affect and constraint the development of electric cars. The convenience, economy and security of charging system directly decides and affects the development process of electric cars. With the continuous development and progress of electric vehicles, planning and construction of the charging station will enter a large-scale, networked age, the layout plan of the charging station is imminent.This paper combined the development status of electric car charging station and the related research both at home and abroad. According to the practical problems in planning and construction of electric car charging stations, systematically studied the charging facilities layout planning. During construction of the charging station, we shall give full consideration to the economic establishment of the station and the user's convenience, reasonable size to avoid resources idle and waste as well as user's needs of charge. This plan based on the planning scale, studied on the method of charging facilities layout. First of all, according to the different characteristics of cars in the target market, combined regression analysis and Bass market diffusion model method, established a demand forecasting model of rechargeable electric car. After defined the of electric car charging demand, we focused on the view of how to improve the service levels of charge, established the programming model of charging stations with the queuing theory. On this basis, from point view of the user, established a network layout methodology of charging facilities with gravity method and the facility location theory. Finally, took Tangshan city as an illustrative example to analysis. This research may provide the basis for planning charge station, as well as reference for address selection of charging station which are being planned to build.
