摘要/Abstract

摘要： 为了提高锂电池故障诊断系统的效率,提出一种基于Petri网的锂电池故障诊断系统。通过对锂电池组在充放电过程中会出现单体电池间电压不一致的故障进行分析,建立了基于Petri网的故障诊断模型。该系统能够根据传感器检测到的异常信号,诊断出相应的故障原因。利用state flow根据所建立的故障诊断模型绘制出相应的控制逻辑图,并用simulink进行仿真。模型验证和仿真的结果表明该诊断系统对导致电压不一致的故障原因能够给出更加细致的诊断结果,从而提高电池管理系统的工作效率。

关键词: Petri网, 在线故障诊断, 锂电池, state flow

Abstract: To improve the efficiency of lithium battery fault diagnosis system, a fault diagnosis system based on Petri net is proposed. The fault diagnosis model based on Petri net came from the analysis of the inconsistent voltages between single cell in lithium batteries during charge and discharge. The system can find the fault causes according to abnormal signals detected by sensor. The control logic diagram of the fault diagnosis model is established by state flow, and simulated by simulink. The results of model verification and simulation show that the cause for inconsistent voltage is distinguished meticulously by the fault diagnosis system; thereby the efficiency of the battery management system is improved.

Key words: petri net, online fault diagnosis, lithium battery, state flow
