Title
(EN) SYSTEM FOR DIAGNOSING INSULATING ELEMENT IN BMS
(ZH) 用于诊断BMS中的绝缘元件的系统
Abstract
(EN) The present invention relates to a system, for diagnosing an insulating element in a BMS, which obtains a battery pack diagnostic signal, being output by means of a battery monitoring circuit and passing an insulating element, from an input terminal and output terminal of the insulating element and then diagnoses for abnormalities in the insulating element on the basis of a bit arithmetic operation of the obtained battery pack diagnostic signal, or which obtains a communication signal, being transmitted and received, from the input terminal and the output terminal of the insulating element andthen diagnoses for abnormalities in the insulating element on the basis of a bit arithmetic operation of the obtained communication signal for transmission and reception.
(ZH) 本发明涉及一种用于诊断电池管理系统(BMS)内的绝缘元件的系统,其中绝缘元件的输入端子和输出端子获得通过电池监控电路输出并且经过绝缘元件的电池组诊断信号并且然后基于所获得的电池组诊断信号的位运算值诊断绝缘元件的异常,或者绝缘元件的输入端子和输出端子获得收发的通信信号并且然后基于用于所获得的收发的通信信号的位运算值诊断绝缘元件中的异常。
