中文摘要: 电池管理系统(BMS)主要功能是实时监控、管理动力电池组中各单体电池的正常工作, 电池的各项信息被BMS以CAN报文的形式发出. 通过采集和解析BMS的报文, 能够对电池的性能作进一步分析评测. 本文以树莓派为载体, 通过设计树莓派的扩展板实现CAN报文的采集, 同时在树莓派中解析CAN协议的DBC文件格式. 设计了一款可移动便携式的CAN报文采集与解析设备, 并根据电池组所有电芯开路电压的解析数据对电池一致性做出快速评估.
Abstract:The main functions of a Battery Management System (BMS) are to monitor and to manage the normal work of each single battery cell in the power battery pack. The information of the battery are sent out by BMS in the form of the CAN message. By collecting and analyzing the BMS messages, the performance of the battery can be further analyzed and evaluated. This study used Raspberry PI as the carrier, realizing the CAN message collection by designing an extension board of the Raspberry PI, and the messages were interpreted as CAN protocol DBC file format in Raspberry PI. According to the open circuit voltage of all cells in the battery pack, the battery consistency was quickly evaluated.
