(DE) SYSTEM ZUR DIAGNOSE EINES ISOLATIONSELEMENTS IN BMS
(EN) SYSTEM FOR DIAGNOSING INSULATING ELEMENT IN BMS
(FR) SYSTÈME DE DIAGNOSTIC D'ÉLÉMENT ISOLANT DE BMS
Abstract
(EN) The present invention relates to a system for diagnosing an insulation element within a battery management system (BMS), in which an input terminal and an output terminal of an insulation element obtain a battery pack diagnosis signal that is output through a battery monitoring circuit and passes through the insulation element, and then abnormality of the insulation element is diagnosed based on a bit operation value of the obtained battery pack diagnosis signal, or an input terminal and an output terminal of the insulation element obtain a transceived communication signal and then abnormality of the insulation element is diagnosed based on a bit operation value of the obtained transceived communication signal.
(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.
