Abstract

L'invention concerne un procédé de supervision d’une batterie électrique de véhicule automobile, le procédé comportant les étapes suivantes :- une étape (100) de détermination d’un besoin en diagnostic électrique d’un réseau basse tension conduisant à la mise à jour d’une variable de besoin en diagnostic électrique (10, 10a, 10b) en fonction de l’au moins une condition testée,- une étape (200) de pilotage spécifique de la batterie électrique en fonction de la variable de besoin en diagnostic électrique(10, 10a, 10b),- une étape (300) de diagnostic de la batterie électrique  durant laquelle plusieurs paramètres caractéristiques (13, 14, 130, 140, 16, 17, 18) sont déterminés,- une étape (400) d’analyse des paramètres caractéristiques (13, 14, 130, 140, 16, 17, 18) déterminés durant l’étape de diagnostic (300), - une étape (500) de détermination d’au moins un état de diagnostic (150) de la batterie électrique. Fig. 1The invention relates to a method for supervising a motor vehicle electric battery, the method comprising the following steps:- a step (100) for determining a need for electrical diagnostics of a low-voltage network leading to the update of an electrical diagnostic requirement variable (10, 10a, 10b) as a function of the at least one condition tested,- a step (200) for specific control of the electric battery as a function of the diagnostic requirement variable battery (10, 10a, 10b), - a step (300) for diagnosing the electric battery during which several characteristic parameters (13, 14, 130, 140, 16, 17, 18) are determined, - a step (400) for analyzing the characteristic parameters (13, 14, 130, 140, 16, 17, 18) determined during the diagnostic step (300), - a step (500) for determining at least one diagnostic state (150 ) of the electric battery.
