摘　　要：为监控电车蓄电池充放电工作状态,及时发现电池异常问题,设计实现了蓄电池充放电参数实时检测系统。介绍了检测系统的系统结构,包括下位机电池检测单片机系统和上位机充放电参数实时监测管理软件系统两部分,以及充放电硬件结构。然后,设计实现了上位机和下位机通信协议,包括通信数据结构、协议帧命令定义和帧格式等,并给出了通信流程的说明。最后,设计开发了上位机主机应用程序,实现系统管理和控制。试验表明,该系统检测准确、运行稳定,能较好监控电池充放电过程。To monitor the working state of charging and discharging of storage battery, timely discovery abnormal problem of battery,this paper designed and implemented the storage battery charge and discharge parameters real-time measuring system. It presented the system structure, including the lower-position battery testing single-chip system and host computer management software system of charge and discharge parameters real-time monitoring, and introduced the hardware structure of charge and discharge. Then,it designed and realized the communication protocols of the host computer and slave computer, including data structure, communication protocol frame command definition and frame format. In addition, it gave the communication process description. And it developed the host application, to control and manage the system. The test shows that the system has high stability and accuracy, and can better monitor the process of charging and discharging.
