| Against the background of increasingly serious urban pollution,new energy vehicles are developing rapidly.In order to make the new energy vehicle industry develop more widely,each country will first promote the application of new energy vehicles in the public transportation system.Pure electric buses have the advantages of environmental protection,low noise and smooth running process,so they are quickly welcomed by majority of passengers.More and more cities begin to use pure electric buses.Currently,the bottleneck restricting the development of electric buses is the lag of charging infrastructure.The establishment of a complete and standard charging station needs to be taken into consideration from the types and scale of charging stations.These two aspects directly affect the operating efficiency and service quality brought by the charging station,which requires scientific methods for decision-making.By analyzing the operation characteristics of pure electric buses,such as running route,departure time,running time,etc.,and combining the problems encountered in the construction process of charging stations,this paper makes a systematic study on the construction types of charging stations for pure electric buses.Firstly,this paper introduces the characteristics of electric buses and their operation and scheduling modes,and analyzes the advantages and disadvantages of different charging modes.Thus,the types of charging stations established in this paper are determined.Secondly,a model of pure electric bus charging station construction aiming at minimizing the charging time of electric buses is built.The model is based on the constraints of charging capacity,departure interval,operating mileage and construction budget.In this paper,when charging time is calculated,GAMS software is used to solve the model,and the types of charging station construction and charging activities of electric buses can be determined.Then,taking a certain region of Shijiazhuang city as an example,the charging station types of pure electric buses in the region were studied,and the influence of technical conditions on the selection of charging station types was analyzed.Finally,the pure electric bus charging station type selection problems expand,to join the study of charging station construction scale,set up with many kinds of charging time to minimize the charging station type selection and the scale model,in addition to the above case,the corresponding analysis and analysis of technical conditions change to charging station type selection and the influence of size. |
