The Study Of Public Charging Infrastructure For Vehicle

This paper focuses on the extended research of electric vehicle charging facilities,which was commissioned by XJ Group. The research content and workflow aredetermined from the perspective of "Construct Matters", which is proposed by LiuGuanzhong in "Design Cybernetics" theory. Firstly, the project background is analyzed,including the environmental problems forcing electric vehicles to develop,promulgation of policies stimulating charging facilities to be constructed, etc.. Also,the investigation of the charging facilities in United States, Japan, Britain, Israel, aswell as domestic supplier, such as BYD, Auto Electric Power Co., Ltd., NARI, etc.,the company size of which is basically the same with XJ Group. According to thefindings of the investigation, a EV charging system need to be established soon, andthe charging stations in the system need to be setted both for the existing and thepotential users, which is different from the existing charging stations, only for specialvehicles. Secondly, this paper studies the user’s charging requirements, and dividesthem into different regions through hierarchical clustering. The core formed by eachone cluster is the optimal location of the charging station in the corresponding stage ofthe phased construction process. This method is in line with the concept andevaluation system of “Design Cybernetics”, which would meet the needs of users,without causing waste of resources. After that, two schemes of charging products areformed initially, according to the psychological characteristics and behavior of EVusers, based on the system theory and modular design method. One of them is provedto be reasonable and ergonomic due to the assessment results. Finally, the positioningAPP is designed to help users find the nearest charging station soon, and the "lastmile",(that is, the distance from the charging station to the destination) issuesgenerated by the public charging network is discussed, and a viable solution isproposed.There are three innovations in this paper, one is the application of the “DesignCybernetics” in the determination of the workflow, the another is the use of cluster analysis for the optimal siting of "nodes" in charging network, and the last one is usingsystems theory and modular design method for product design. These innovations willbenefit both recent and long-term construction of the public charging system.
