设计了一套动力电池包故障诊断系统。针对动力电池包故障系统的总体方案进行了研究,并对系统的主要功能进行了介绍。系统中涉及的BMS采用总分式结构,动力电池包BMS主要对总电流、总电压及绝缘进行检测;模组BMS负责对电池模组进行基本参数的采集及诊断。系统的测试结果表明:该系统准确可靠,可用于对动力电池包进行故障诊断。

A power battery package fault diagnosis system is designed and developed in this paper. The design of the overall scheme of the battery pack failure system is studied,and the main functions of the system are also introduced. The BMS in volved in the system employs a total fraction structure,the power battery pack BMS mainly detects total current,total voltage and insulation,module BMS is responsible for the acquisition and diagnosis of the basic parameters of the battery module. The test results of the system show that the work is accurate and reliable,and can be used to diagnose the power battery pack.
