Research And Design Of Charging Management System For Electric Vehicle Based On PHP

Based on actual demands, keeping up with the rapid development of mobile Internet, a charging management system for electric vehicles was designed using the open source PHP back-end technology in this paper. Development of electric vehicle charging management system is an inevitable trend for the automation, information, facilitation and long range of charging process. On the basis of charging ability, charging management system makes more convenient applications for charging posts, such as mobile phone Apps which achieve unified management of users’ charging information, real-time tracking of charging process, no-card payment mode of mobile phones etc. Charging management system is not only an important means for the universal access of electric vehicles, but also an inevitable trend of mobile Internet.This paper first analysed the current existing problems and inconvenient operations of charging posts, determined the general function design of PHP-based electric vehicles charging management system in accordance with the demands of mobile phone payment means. Furtherly, supports of mobile phone Apps were analysed modularly, while functional improvements were made on charging posts. Charging management system was devised using MVC pattern which divides the system into four main modules: charging posts, mobile phone Apps, database and customer information management services. Communication between charging and management, also between mobile phone Apps and management system, transmission and receiving of data, and database table design were majorly analysed. According to the existing problems, this paper chose LQ1001 DTU GPRS as an extension module to communicate with the server. Simultaneously, VC++ Socket multithreaded programming was used to achieve transmission and receiving of data, Communication between mobile phone Apps and management system was realized by taking advantage of open source PHP back-end scripts, Ajax asynchronous communication technology and basic web programming languages like HTML, CSS, and javascript. On the basis of data types and analysis of logical requirements, database tables were designed using relational database MySQL.Electric vehicle charging management system is a hybrid structure which bases on B/S and C/S. This system has the advantages of practical functionalities, easiness to use, short development cycles, low cost and simple system upgrade. Compared with similar management systems, this system combines management with applications, which makes it of high practical values.
