| With the acceleration of urbanization and motorization,global energy,environment and climate change are becoming more and more prominent,among which the sustainable development of transportation and environment has also attracted wide attention at home and abroad.Facing the severe situation of environmental energy hazards,electric vehicles(EVs),as an energy-efficient carrier,use electricity instead of oil,the use of the process will not produce exhaust gas,can effectively achieve ’zero emissions’,in improving air quality,mitigating global warming has great application potential.In order to promote the development of EVs,China has introduced a series of strategic plans,relevant policies and regulations and supportive policies to promote the development of EVs.However,due to the lack of exploration of the internal mechanism of the use behavior of EVs’ consumers,the market diffusion of EVs has been hindered by various factors.Therefore,it is of great theoretical and practical significance to explore the characteristics of EV consumer behavior and the factors influencing the diffusion of the market,to formulate more accurate support policies for EVs,to maximize the promotion of EV marketization,and to promote the sustainable development of transportation.The paper systematically explores the consumer behavior,charging behavior and purchase behavior of EVs,analyzes the factors of the diffusion of EV market,and the main aspects are as follows:Firstly,analyse the behavior characteristics and running time and space characteristics of electric minibus and electric taxi drivers.Based on the GPS positioning data of electric minibuses and the relevant data of electric taxi industry in Beijing,the behavior characteristics and running time and space characteristics of electric minibus and electric taxi drivers are explored,including the average number of trips per day,the average mileage,the capacity of the taxi industry,the change of driver’s income,the change of vehicle power exchange,etc.In addition,the characteristics of electric taxi passengers’using behavior are analyzed from the perspectives of convenience,economy and comfort.And then,from the express transport,agricultural products transportation,moving transport and household goods distribution four areas of analysis of the new energy truck driver’s use behavior characteristics.Secondly,propose the influence-factors measuring model of the fast charging behavior under the China traffic background,analyse the charging behavior scheme of the EV consumer.Existing studies on influencing factors of EV charging behavior are rarely based on actual EV charging data in China.The fast charging data of EV drivers is extracted separately,and the characteristics of the fast charging behavior of EV drivers in China and their influencing factors are analyzed,based on the charging data in Beijing,China.Whether to choose fast charging behavior as a dependent variable,select battery properties,travel characteristics and environment as the independent variables,construct a measurement model of the impact of EV driver’s fast charging behavior,explore the key factors affecting EV driver’s fast charging behavior and its specific impact degree.Thirdly,based on the running data of actual logistic EVs and charging facilities,evaluate the facility utility,put forward the evaluation mode derived from the grey premium evaluation method.Based on the positioning data of 5000 pure electric logistics vehicles in Beijing and the operation data of 2700 public charging piles in the city,the charging characteristic behavior of new energy trucks in Beijing is characterized,including the starting charging position of vehicles,the characteristics of single charging power,and the distribution of charging position in the city is analyzed.C ombining the car-side data and the pile-side data,form the charging facility layout evaluation index scheme,evaluate the performance of the use of social charging piles(large piles)and the layout of the charging facilities in various regions of Beijing.The research puts forward the quantitative evaluation method for the optimization of existing piles and the building plan of the new ones.Fourthly,characterize the EV consumers’ purchasing behavioral changes,explore to use the ’what-if’ scenario method engaged in analysing incentive policies.The classic Howard-Sheth theory is introduced into the purchase behavior of potential consumers of EVs,which divides the process of consumer purchase into four stages:’neglect and neglect’,’active concern’,’comparison and selection of vehicles’ and’evaluation of use’,and systematically explores the changes in attitudes and internal causes of potential consumers of EVs at different stages of the purchase process.Assess the impact of several typical EV-related policies and environmental factors on individual buying behavior by establishing ’what-if’ scenarios.Fifthly,from promoting charging infrastructure construction,operation,and guiding the electricity,the electric car consumers to develop electric vehicles involved in electric power market strategy research,put forward the electric car aggregators participate in electricity market three business model,and by using the method of costbenefit analysis,based on reasonable hypothesis,carried out three kinds of whole life cycle of business model analysis of the economy.Finally,the future development of EV is analyzed from the two levels of EV and related basic charging facilities.On this basis,from the EV technology,infrastructure,industrial planning and safeguard measures and other aspects of the rationalization of the development of EV industry,in order to provide an important reference for the market diffusion and sustainable development of EV industry. |
