Design And Implementation Of Electric Vehicle Charging Service System Based On The Android Platform

In recent years,with the rapid spread of electric vehicles,the demand of charging is also growing.As the best way for electric vehicles to add electricity,Charge pile also get rapid development.But the lack of charging service constraints the industry of the entire charge pile and even the development of new energy automotive industry.The paper designs a set of new charging service system which is based on mobile terminal,it can satisfy the diversified demands of electric vehicle charging customers.The paper deeply explores the multi-level requirements of electric vehicle users to charge,and divides the system into user management,map service,online payment,charge monitoring and user comments.On this basis,the paper completed the C/S architecture design between the module of system client?server?database and charging.The paper Uses GPRS DTU as the charging pile network module and Socket technology to complete the design of communication module between charge pile and the server.The paper Uses HttpClient technology and asynchronous way to complete the client-server interaction module design.The design of the data exchange module of the whole system is completed with XML as the data format.The design of the client function module is completed by embedding the third-party interface such as map and payment.Through the use of thread pool technology to complete the server-side concurrent module design.Based on the function of each module of the system,the system database design is completed,including the design of data table and database connection pool.On the basis of the demand analysis and the module design,The paper is based on the MVC layered programming model and uses AndroidStudio and MyEclipse development tools to develop the charging service system client function module and the server program.Finally,The paper completed the test of system functions,compatibility,and performance modules.The test results show that the designed system can perform well and operate stably.
