Title
(EN) SYSTEM FOR DIAGNOSING INSULATING ELEMENT IN BMS
(FR) SYSTÈME DE DIAGNOSTIC D'ÉLÉMENT ISOLANT DE BMS
(KO) BMS 내 절연소자 진단 시스템
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 and then diagnoses for abnormalities in the insulating element on the basis of a bit arithmetic operation of the obtained communication signal for transmission and reception.
(FR) La présente invention concerne un système de diagnostic d'un élément isolant d'un BMS, qui obtient un signal de diagnostic de bloc-batterie, délivré au moyen d'un circuit de surveillance de batterie et passant par un élément isolant, à partir d'une borne d'entrée et d'une borne de sortie de l'élément isolant et qui diagnostique ensuite des anomalies dans l'élément isolant sur la base d'une fonction arithmétique binaire du signal de diagnostic de bloc-batterie obtenu, ou qui obtient un signal de communication, transmis et reçu, à partir de la borne d'entrée et de la borne de sortie de l'élément isolant et qui diagnostique ensuite des anomalies dans l'élément isolant sur la base d'une fonction arithmétique binaire du signal de communication obtenu à des fins de transmission et de réception.
(KO) 본 발명은 배터리 모니터링 회로를 통해 출력되어 절연소자를 통과하는 배터리팩 진단신호를 절연소자의 입력단 및 출력단에서 획득한 후 획득된 배터리팩 진단신호의 비트연산값을 토대로 절연소자의 이상을 진단하거나, 송수신되는 통신신호를 절연소자의 입력단 및 출력단에서 획득한 후 획득된 송수신용 통신신호의 비트연산값을 토대로 절연소자의 이상을 진단할 수 있는 BMS 내 절연소자 진단 시스템에 관한 것이다.
