Abstract

L’invention concerne un procédé de compensation d’une batterie de traction (1) hors de son état nominal de fonctionnement sans être défectueuse dans un réseau électrique d’un véhicule automobile comprenant un premier réseau de traction (3) à haute tension et un deuxième réseau de bord (2) à basse ou moyenne tension en parallèle l’un de l’autre, la batterie (1) alimentant le premier réseau (3) équipé d’un onduleur (5) et d’une machine électrique (4) et le deuxième réseau raccordé par un convertisseur (6) de courant continu DC/DC à la batterie de traction (1). Une batterie de traction (1) hors d’état nominal, est déconnectée et la machine électrique (4) est activée en contrôle en tension. Un fonctionnement nominal du convertisseur (6) est suspendu dès que la comparaison atteste que la batterie de traction (1) est hors de son état nominal. Figure 1The invention relates to a method for compensating a traction battery (1) out of its nominal operating state without being defective in an electrical network of a motor vehicle comprising a first high voltage traction network (3) and a second on-board network (2) at low or medium voltage in parallel with each other, the battery (1) supplying the first network (3) equipped with an inverter (5) and an electric machine (4 ) and the second network connected by a DC / DC direct current converter (6) to the traction battery (1). A traction battery (1) out of nominal state is disconnected and the electrical machine (4) is activated in voltage control. Nominal operation of the converter (6) is suspended as soon as the comparison shows that the traction battery (1) is out of its nominal state. Figure 1
