摘要：

为保证锂离子蓄电池在使用过程中的高可靠性,需对电压、电流、温度等参数进行实时监测。该文设计一种基于CAN2.0B协议的锂离子蓄电池管理系统通信网络,采用iCoupler磁隔离技术完成网络通信接口的硬件电路设计,并对CAN通信网络内报文数据格式及扩展标识符的分配方法做统一规定,在此基础上完成系统软件设计。通过现场测试,结果显示报文以60 ms为周期在整个CAN通信网络中准确、不间断地传输,符合锂离子蓄电池管理系统对于实时性和可靠性的要求。

Abstract: In order to satisfy the request of high reliability in using lithium ion battery, monitoring voltage, current and temperature of batteries in real time is necessary. A communication network based on the protocols of CAN2.0B in lithium ion battery management system was designed. With the technology of iCoupler magnetic isolation, the hardware circuit of communication network interface was designed. And also, based on the uniform data format and distribution method of extended identifier in communication network, the software was designed. The authors tested the CAN bus communication network on site. The results are that messages for 60 ms-cycle transmit uninterruptedly and accurately in the communication network. The test results show that the design of the communication network based on the CAN bus can meet the request of high real-time and reliability in lithium ion battery management system.

Keywords: CAN bus; lithium ion battery management system; communication network; iCoupler magnetic isolation
