Abstract

Le procédé est mis en œuvre dans un véhicule électrifié du type ayant un réseau électrique de bord (RDB) comprenant un stockeur électrique (BT_BAT), un générateur électrique (C_DC/DC) et un dispositif d’isolation électrique et de test (DEx) associé au stockeur pour isoler électriquement le stockeur lors d’un test de celui-ci et connecter électriquement le stockeur au générateur à la fin du test, le procédé assurant une supervision d’une défaillance du dispositif d’isolation électrique et de test à connecter le stockeur au générateur à la fin du test. Conformément à l’invention, le procédé comprend les étapes de a) détecter (BF1, DCS) une défaillance du dispositif d’isolation électrique et de test à partir d’au moins une information (BIC, DIAG) fournie par celui-ci et une information de roulage (VRS) du véhicule ; et b) réduire (BF2, LP_ESP/DAE, REC) la consommation électrique du réseau électrique de bord lorsqu’une défaillance est détectée à l’étape a). Figure 2The method is implemented in an electrified vehicle of the type having an on-board electrical network (RDB) comprising an electrical store (BT_BAT), an electrical generator (C_DC/DC) and an electrical isolation and test device (DEx) associated with the storer to electrically isolate the storer during a test thereof and electrically connect the storer to the generator at the end of the test, the method ensuring supervision of a failure of the electrical isolation and test device to be connected the storer to the generator at the end of the test. According to the invention, the method comprises the steps of a) detecting (BF1, DCS) a failure of the electrical insulation and test device based on at least one piece of information (BIC, DIAG) provided by it and driving information (VRS) of the vehicle; and b) reduce (BF2, LP_ESP/DAE, REC) the electricity consumption of the on-board electrical network when a failure is detected in step a).
