Abstract
(DE)
Die vorliegende Erfindung schafft ein Verfahren zur Erkennung eines Defekts einer Batterie (B) in einem Niederspannungsbordnetz eines elektrischen Fahrzeugs. Das Verfahren umfasst den Schritt Anlegen (S1) eines elektrischen Verbrauchers (L) des elektrischen Fahrzeugs an das Niederspannungsbordnetz. Weiterhin umfasst des Verfahren den Schritt Erfassen (S2) eines resultierenden Spannungseinbruchs der Batterie (B) des Niederspannungsbordnetzes mit einem Spannungssensor (V). Weiterhin umfasst das Verfahren den Schritt Bestimmen (S3) des Defekts, wenn der erfasste Spannungseinbruch ein vorgegebenes Kriterium erfüllt. Ferner schafft die vorliegende Erfindung eine Vorrichtung zur Erkennung eines Defekts einer Batterie (B) in einem Niederspannungsbordnetz eines elektrischen Fahrzeugs.
(EN)
The present invention relates to a method for detecting a defect in a battery (B) in a low-voltage electrical system of an electric vehicle. The method comprises the step of applying (S1) an electrical load (L) from the electric vehicle to the low-voltage electrical system. The method also comprises the step of sensing (S2) a resulting voltage dip in the battery (B) of the low-voltage electrical system using a voltage sensor (V). The method also comprises the step of determining (S3) the defect if the sensed voltage dip meets a predefined criterion. The present invention also relates to a device for detecting a defect in a battery (B) in a low-voltage electrical system of an electric vehicle.

La présente invention concerne un procédé destiné à détecter un défaut d'une batterie (B) dans un réseau de bord à faible tension d'un véhicule électrique. Le procédé comprend l'étape consistant à appliquer (S1) un consommateur électrique (L) du véhicule électrique au réseau de bord à faible tension. Le procédé comprend en outre l'étape consistant à enregistrer (S2) une chute de tension résultante de la batterie (B) du réseau de bord à faible tension à l'aide d'un capteur de tension (V). Le procédé comprend en outre l'étape consistant à déterminer (S3) le défaut si la chute de tension enregistrée satisfait un critère prédéfini. La présente invention concerne de plus un dispositif destiné à détecter un défaut d'une batterie (B) dans un réseau de bord à faible tension d'un véhicule électrique.
