摘　　要：介绍了利用嵌入式技术和CAN总线技术设计的电动汽车电池管理系统.电池监控节点以AVR单片机为核心,包括电池参数采集模块、CAN通讯模块、串口通讯模块等.各电池监控节点之间通过CAN总线进行通讯,主节点与上位机之间通过串口通讯.利用S3C44B0X开发板搭建了上位机管理平台,移植了实时操作系统uC/OS-Ⅱ,并将uC/GUI应用于触摸屏,实现了良好的人机交互.电池管理系统可以实现对各个电池电流、电压和温度的实时采集,并在触摸屏上显示,同时可通过触摸屏发送控制指令给各监控节点.经过电池标定试验验证系统是可行的.A battery management system of electric vehicle was designed by utilizing embedded technology and CAN bus technology. These battery monitor nodes with AVR single chips as their kernels, are composed of modules of battery parameter sampling, CAN communication, serial communication, etc. Battery monitor nodes can communicate with each other via the CAN bus, and the main node can communicate with the master controller via the serial port. Master controller platform is set up by utilizing the S3C44B0X developing board, and the operating system uC/OS-Ⅱ is transplanted. The uC/GUI is applied to the touch panel so that the human-computer interaction is friendly. Battery＇ s current, voltage and temperature are gathered by the battery management system in real time. And these parameters are displayed on touch panel. Also control orders can be sent to these monitor nodes by the touch panel. The calibration experiment verified that the battery management system of electric vehicle was feasible
