非车载充电机与BMS通信协议标准解析与对比

Comparative Analysis of Communication Protocol Standards Between Off-board Charger and BMS

随着我国电动汽车的大力推广,大功率非车载充电机也逐渐普及,然而当前市场上非车载充电机的通用性较差,充电机与BMS的通信协议不唯一。本文介绍了我国电动汽车非车载充电机与电池管理系统通信协议的标准制定情况,并将《GB/T 27930-2011电动汽车非车载传导式充电机与电池管理系统之间的通信协议》《NB/T 33003-2010电动汽车非车载充电机监控单元与电池管理系统通信协议》《QC/T 842-2010电动汽车电池管理系统与非车载充电机之间的通信协议》与《SZDB/Z 29.8-2010电动汽车充电系统技术规范:第8部分:非车载充电机监控单元与电池管理系统通信协议》进行对比分析,并对非车载充电机标准统一和修订工作的开展提出建议。

With the promotion of electric vehicles, off-board charger is also becoming more common However, the generality of off-board chargers on the current market is poor and communication protocols between off-board charger and battery management system （BMS） are not unique. In this paper, the standards of the communication protocol of China are introduced and compared Recommendations for uniform and revision of the communication protocol standards are made.
