Design Of Space Linkage System Of Electric Vehicle Battery Life Under Range Anxiety

In recent years,promoted by relevant policies and new energy travel concept,the industry of electric vehicles has made rapid development,which has also led to a wave of consumption of electric vehicles.However,such advanced users will also face range anxiety caused by many factors such as the lagging infrastructure construction,the limited development of related technologies,and the promotion of related public opinion under this new mode of travel.Therefore,improving the overall vehicle technical level and service quality—gradually and technically extending battery life,shortening charging time,and increasing charging infrastructure in the use of electric vehicles—will effectively relieve the users’ range anxiety,and further increase the sales and utilization of electric vehicles,and as a result,it will be able to not only achieve energy conservation and environmental protection but also make a steady improvement in new energy travel industry.In accordance with the requirements of relevant norms and technologies,this thesis analyzes the status and trends of electric vehicles’ development in battery endurance and power enhancement;based on the investigation and research on the products of battery endurance and energy enhancement,the thesis summarizes the reasons for range anxiety and its main effects;guided by the spatial linkage theory,the paper also analyzes the application fields and cases,and then summarizes the basic characteristics,and proposes a design pattern involving methods,thoughts in application,elements and framework;by making a survey among users and analyzing the problem of taking long charging time and having few charging facilities in long-distance or short-distance travel,it is concluded that products need to adapt to the local conditions and have the attributes to make adjustments dynamically.On the basis of the above research,the practice — designing spatial linkage system about the electric vehicle endurance—is carried out.It is recommended to combine the charging station with the expansion station.According to the service system,an automatic non-perceived charging method is proposed;a non-perceived charging station is also designed,in which the charging of electric vehicles is changed from passive manual work to active mechanized work,thus weakening the charging behavior of users;a dynamic endurance method is suggested and a dynamic capacity expansion station is designed so that users can increase the vehicle’s endurance by leasing battery for more power,hoping to provide a reference for the design of spatial linkage of electric vehicle.
