摘　　要：随着电池组储能需求的持续增加,电压平台也随之升高,对高压系统绝缘性能的实时监测显得越发重要。对几种常用的绝缘电阻检测方法进行深入地研究分析,提出平衡-非平衡电桥的绝缘电阻检测方法,利用Multisim搭建整车绝缘仿真模型,对平衡-非平衡电桥的绝缘电阻检测方法进行可行性分析。结果表明该方法检测绝缘电阻的模型是可以实现的,能满足电动汽车的要求,为电池管理系统设计提供支持。As the demand for battery pack energy storage continues to increase and its voltage plateau rises,the real-time monitoring of the insulation performance of high-voltage systems becomes more and more important.In this paper,several common methods of insulation resistance detection are analyzed,the insulation resistance detection method of the balanced-unbalanced bridge is proposed,and Multisim is used to build a whole vehicle insulation simulation model to analyze the feasibility of the insulation resistance detection method of a balanced-unbalanced bridge.
