Title (EN) METHOD FOR MANAGING THE STATE OF CHARGE OF A HYBRID VEHICLE
(FR) PROCEDE DE GESTION DE L'ETAT DE CHARGE D'UN VEHICULE HYBRIDE
Abstract:
(EN) The present invention relates to a method for managing the state of charge of a traction battery of a hybrid vehicle power train. It comprises, during a taxiing phase of the vehicle to a current destination: - a step of predicting the temperature that the battery will reach, after the power train has been extinguished, at a time of departure to a future destination; - a step of estimating, according to the battery temperature predicted previously, a minimum state of charge of the battery to provide, during a taxiing phase to the future destination, a predefined minimum power level; - a step of maintaining the state of charge of the battery in the region of the minimum state of charge. Application: hybrid vehicles.
(FR) La présente invention concerne un procédé de gestion de l'état de charge d'une batterie de traction d'un groupe moto-propulseur d'un véhicule hybride. Il comporte, durant une phase de roulage du véhicule vers une destination courante : - une étape de prédiction de la température qu'atteindra la batterie, après extinction du groupe-motopropulseur, à un instant de départ vers une destination future; - une étape d'estimation, en fonction de la température de batterie prédite précédemment, d'un état de charge minimal de la batterie permettant de fournir, durant une phase de roulage vers la destination future, un niveau de puissance minimal prédéfini; - une étape de maintien de l'état de charge de la batterie au voisinage de l'état de charge minimal Application : véhicules hybrides
