Life Cycle Assessment Method And System Development Of Electric Vehicles

The development of automobiles not only consumes a lot of earth resources,but also causes a lot of environmental pollution.In the environment of advocating energy conservation and environmental protection,electric vehicles have been vigorously developed.Although electric vehicles can reduce the pressure of domestic oil shortage and environmental pollution through the use of electricity,this only considers the use stage,and does not analyze its comprehensive impact on the environment from the perspective of the full life cycle of products.As the electric energy used by electric vehicles is a kind of secondary energy,which actually comes from the burning of fossil fuels,and the production and scrapping of electric vehicle power cells also need to consume a lot of energy and emit pollutants.Therefore,it is necessary to comprehensively evaluate the energy consumption and environmental impact of the production,use and scrapping of electric vehicles from the perspective of the whole life cycle.In this paper,through consulting the relevant literature on the life cycle assessment of electric vehicles,we understand the life cycle activities of electric vehicles,collect inventory data,and build an electric vehicle life cycle assessment model.On this basis,we use the Spring Boot framework deployment in Java language and Intelli JIDEA development tools to design and develop an electric vehicle life cycle assessment system.The main research contents include:(1)The technical framework of life cycle assessment is studied in depth.Based on the characteristics of electric vehicles,the research objectives,research scope and other issues are discussed in detail,and the life cycle assessment model of electric vehicles is proposed.(2)Inventory data collection,including the collection of input and output data involved in each unit process of the model,provides data support for the design and development of subsequent systems.(3)Based on the implementation process of the electric vehicle life cycle assessment system,this paper introduces the development environment of the assessment system,analyzes the requirements of the assessment system,and then designs the overall framework,process analysis,interface design,database design of the assessment system according to the system requirements,and introduces the key technologies used by the system.Finally,this paper introduces the implementation process of the assessment system.(4)Example application.(5)Characterize the environmental impact type of the system results,and the environmental impact potential value of the whole life cycle of electric vehicles is obtained.The life cycle assessment system of electric vehicle is a software that uses Web server as the carrier and electric vehicle as the object to conduct life cycle assessment.Different users can operate it through Web browser pages.The software is divided into foreground operation module and background management module.The foreground operation module includes the input of basic vehicle parameters and the output of data after data input.The background management module includes the use of My SQL database to store list data and compile algorithms to achieve the correlation between the foreground interface and the background management.In order to verify the realization of the system functions,this paper uses this system to study the energy consumption and gas emissions in the life cycle of Qin PLUS 2021 EV600 km flagship,Rongwei i6MAX2021 1.5TPHEV flagship version and Lavida 2022 1.5L automatic fashion version.The results show that the system can calculate the resource consumption and gas emissions within the life cycle of electric vehicles and traditional fuel vehicles,and can greatly shorten the life cycle assessment time,help electric vehicle designers to select the most energy-saving and environment-friendly design scheme,and promote the development of life cycle assessment methods in the field of electric vehicles.
