Abstract

L'invention concerne un procédé de contrôle d’un ensemble électrique relié électriquement à une batterie électrique de véhicule automobile, le procédé comportant les étapes suivantes :- une étape (100) d’estimation d’au moins un paramètre caractéristique (11, 12) de la batterie électrique à l’aide d’un calculateur surveillant l’activité de la batterie électrique,- une étape (200) de détermination d’au moins une limite de tension de polarisation (130, 131) de la batterie électrique au-delà de laquelle la batterie électrique pourrait être endommagée,- une étape (400) de définition d’une consigne de tension de polarisation (17) de la batterie électrique en fonction de l’au moins limite de tension de polarisation (130, 131) déterminée précédemment et permettant de limiter une sollicitation électrique de la batterie électrique. Fig. 2The invention relates to a method for controlling an electrical assembly electrically connected to a motor vehicle electric battery, the method comprising the following steps:- a step (100) for estimating at least one characteristic parameter (11, 12 ) of the electric battery using a computer monitoring the activity of the electric battery, - a step (200) of determining at least one bias voltage limit (130, 131) of the electric battery at the -beyond which the electric battery could be damaged,- a step (400) of defining a bias voltage setpoint (17) of the electric battery as a function of the at least bias voltage limit (130, 131 ) determined previously and making it possible to limit electrical stress on the electric battery.
