Electric Vehicle AC Charging Pile And Its Billing Management System Design

In recent years,the problem of air can not be underestimated in China.The impact it brings is ubiquitous and affects people's normal lives.Among them,automobile exhaust is one of the important sources of pollution.It's “producer” fuel vehicle brings convenience to people,and it's exhaust emissions also brings an ever-increasing environmental pressure.Compared with fuel vehicles,electric vehicles have a relatively small impact on the environment,have zero emissions,high energy efficiency,and their prospects are widely seen.With the rapid development of electric vehicles,higher requirements have been put forward for related technologies of charging piles,and the demand for charging piles has also been greatly improved.The development of charging piles will restrict the development and popularization of electric vehicles.This paper designs and implements the charging management system for AC charging piles of electric vehicles based on the embedded system model.The system is mainly composed of an embedded system control module,a metering and billing module,and a human-machine interaction module.Through embedded system can control and transmission of data,billing metering and man-machine interaction are completed,and functions such as control,monitoring and display of the charging status of electric vehicles are realized.This article begins with the whole,completes the overall system design according to the relevant national standards and functional requirements,establishes the overall framework of the system,divides the whole into charging pile core systems and human-computer interaction systems,and then determines the charging pile core according to the overall system design.The system's hardware and software design,human-computer interaction system uses the underlying Android operating computer developed for the Linux system,and through the touch screen to achieve interaction.Refer to the national grid standard,use the embedded system to monitor the current grid status;design a GUI human-computer interaction interface for the user experience experience,pass the user operation command to the charging pile control core MCU through the APP,and complete the corresponding command operation through the MCU control and data transmission,at the same time IPC through wireless network and billing management system interconnection,unified management of user information.The design goal of this paper is to realize the basic functions of AC charging piles andto achieve convenient human-machine interaction.At the same time,it strives to bring users a better experience.
