Title
(EN) SYSTEM FOR DIAGNOSING INSULATION ELEMENT IN BMS
(KO) BMS 내 절연소자 진단 시스템
Abstract
(EN) The present invention relates to a system for diagnosing an insulation element in a BMS. In diagnosing abnormality of an insulation element dividing a BMS according to voltage areas, the system can diagnose abnormality of the insulation element based on a bit operation value of a battery pack diagnosis signal after obtaining the battery pack diagnosis signal, which is outputted through a battery monitoring circuit and passes the insulation element, from an input terminal and an output terminal of the insulation element or can diagnose abnormality of the insulation element based on a bit operation value of a communication signal for transmission/reception after obtaining the communication signal for transmission/reception from the input terminal and the output terminal of the insulation element.
