【摘要】：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。
[Abstract]:In order to simplify the communication flow between the charger and the battery management system (BMS), and to identify and classify the data transmitted by BMS, the research and analysis of the National charging Standard Protocol (GBT / 27930-2011) are carried out. In this paper, an event triggered communication system between charger and BMS is proposed, which encapsulates the communication flow specified by the new national standard charging protocol according to event trigger sequence. The research results show that the communication system can realize the functions of receiving, recognizing, analyzing, classifying, transmitting and answering the BMS data. The communication flow is optimized to provide a convenient reference for the design of communication between charger and BMS.
