| With the promotion of the new energy industry,especially the pure electric automobile industry in recent years,the development of pure electric automobiles has shown a blowout trend,major automotive enterprises have entered the field of electric automobiles,and the market of electric automobiles has also been increasing.Based on the huge market potential,the construction of charging stations as a source of energy supply for electric vehicles attracts various kinds of social capital to put charging stations into operation due to various factors such as low entry threshold and small technical barriers.However,due to insufficient pre-market research or overdue investment in order to seize the late potential market,some charging stations have lower operating efficiency.In the face of this problem,this paper establishes the evaluation model of the operational efficiency of bus charging stations and puts forward the operation optimization strategy,which provides inspiration for improving the efficiency of charging stations from the perspective of project design and operation.First,this paper takes the bus charging station in operation as an example,and according to the statistical data in the operation process,evaluates the operating efficiency of charging stations by data envelope analysis(DEA),and compares and analyses the operating efficiency of each charging station.Then,from the perspective of supply-demand relationship matching,the key factors that affect the operating efficiency of each charging station are identified.Furthermore,a causal relationship model is established to predict the charging demand and service supply capacity of charging stations in the bus and social vehicle markets,and an overall operation optimization scheme for multi-charging stations in the region based on the minimum of basic functions and social costs is proposed.The core idea of the optimization scheme is to use the remaining service capacity of the charging station to open the charging service business to social vehicles.Finally,on the basis of investigating the charging demand of electric vehicle in peak time,this paper analyses the two situations of over-supply and under-demand of charging station based on queuing theory,and puts forward the strategies to improve the operating service system of a single charging station to improve the operating efficiency of the supply side. |
