中文摘要:

      随着国家对新能源开发的投入，电动汽车的发展已经成为人们关注的焦点。此设计使用基于Android 6.0嵌入式操作系统，Cortex-A9系列工业级ARM处理器支持电容触摸屏Exynos 4412开发板。针对电动汽车交流充电桩的用户图形界面开发进行了研究，介绍了充电界面的开发流程和具体实现。其中主要包括窗口函数的设计、充电实时数据的显示和读取、交叉编译以及内核移植，通过JNI的开发，完成对串口的通信。实验表明，与现有充电管理系统相比，该系统能够人性化地完成充电模式选择，准确地采集充电信息和完成用户下达的充电指令，不仅处理速度快，而且功能和可扩展性更强。本设计具有创新性、稳定性和实用性，符合国家在2016年1月1日颁布的对电动汽车充电指标的要求，具有较高的实用价值，能够很好地为电动汽车用户提供充电服务。

英文摘要:

      With the national investment in new energy development,the development of electric vehicles has become the focus of attention.This design was based on Android 6.0 embedded operating system,Cortex-A9 series industrial ARM processor supported the Exynos 4412 development board with capacitive touch screen.Aiming at the development of user graphical interface for electric vehicle AC charging pile,the development process and concrete realization of the charging interface were introduced.It mainly included the design of the window functions,the display and reading of real-time charging data,cross-compiling and kernel migration,and the serial communication was completed through the JNI development.The experiments show that compared with the existing charging management system,the system can humanize to choose the charging mode,precisely collect charging information and perform the charging order of the user,which is not only more rapid but also superior in function and extensibility.This design is innovative,stable and practical,which conforms to the requirements of the national electric vehicle charging index issued on January 1,2016.It has high practical value and provides excellent charging service to the electric vehicle users.
