为简化充电机与电池管理系统BMS的通信流程,并能够对BMS传送来的数据进行辨识和分类,通过对国家充电标准协议(GB/T 27930-2011)的研究和解析,提出了一种基于事件触发的充电机与BMS通信系统.该系统对新国标充电协议所规定的通信流程按事件触发顺序进行逻辑功能函数封装,运用等待固定触发的数据接收方式取代了传统的中断接收方式.研究结果表明,该通信系统能够实现对BMS数据的接收、识别、解析、分类、传输和答复等功能,优化了通信流程,为充电机和BMS的通信设计提供简便的使用参考.%For simplifying the communication between charger and Battery Management System(BMS),identifying and classifying the data that comes from the BMS correctly,a communication system between charger and BMS based on even trigger have been pro posed in this report after studying and analyzing the national standard communication protocols(GB/T 27930-11).The system encapsulates logistic functions for communication flow that defined by the new national standard communication protocol based on the sequence of event trigger and applies the way of waiting fixed trigger data for receiving instead of the traditional interrupt mode.The research shows that this communication system can realize functions such as receiving,identifying,analyzing,classifying,transmitting and responding the BMS data.It optimizes the communication process and provides a convenient reference for the design of communication between charger and BMS.
