Abstract

Procédé (20) de détection de la défaillance d'une batterie 12V d'un véhicule automobile dans lequel lorsque le véhicule automobile est dans une phase de roulage, on génère une consigne de tension basse (CT) selon une pente prédéterminée et pendant une durée prédéterminée, on compare, de manière périodique, une valeur mesurée de tension du réseau avec une deuxième valeur de seuil, et on détermine si la batterie 12V est défaillante en fonction de ladite comparaison, si la tension mesurée du réseau électrique est supérieure ou égale à la deuxième valeur de seuil, la batterie 12V n'est pas défaillante, et si la tension mesurée du réseau électrique est inférieure à la deuxième valeur de seuil, la batterie 12V est défaillante et présente un court-circuit ou un circuit ouvert.Method (20) for detecting the failure of a 12V battery of a motor vehicle in which when the motor vehicle is in a driving phase, a low voltage setpoint (CT) is generated according to a predetermined slope and for a period of time predetermined, a measured value of network voltage is periodically compared with a second threshold value, and it is determined whether the 12V battery is faulty based on said comparison, if the measured voltage of the electrical network is greater than or equal to the second threshold value, the 12V battery is not faulty, and if the measured voltage of the electrical network is lower than the second threshold value, the 12V battery is faulty and has a short circuit or an open circuit.
