Abstract
L’invention porte sur un procédé de protection contre une surtension dans un système comportant une batterie liée à un onduleur par un bus haute tension et une machine électrique pilotée par l’onduleur. Tandis que le système fonctionne en mode de régénération dans lequel la machine électrique fonctionne en générateur pour recharger la batterie, le procédé comporte : - la détermination de la tension sur le bus haute tension ;- la comparaison de la tension déterminée à un seuil de tension (Uth), et- le passage de l’onduleur dans un mode de protection adapté à faire baisser la tension (S6), lorsque la tension déterminée dépasse ledit seuil de tension,Dans l’invention, le seuil de tension est variable en fonction d’un état de charge courant de la batterie.L’invention porte également sur un système correspondant, adapté à mettre en œuvre ce procédé. Figure pour l’abrégé : Fig. 2The invention relates to a method of protecting against an overvoltage in a system comprising a battery linked to an inverter by a high voltage bus and an electrical machine controlled by the inverter. While the system operates in regeneration mode in which the electric machine operates as a generator to recharge the battery, the method comprises: - determining the voltage on the high voltage bus; - comparing the determined voltage to a voltage threshold (Uth), and - switching the inverter to a protection mode adapted to lower the voltage (S6), when the determined voltage exceeds said voltage threshold, In the invention, the voltage threshold is variable depending on of a current state of charge of the battery. The invention also relates to a corresponding system, adapted to implement this method. Figure for abstract: Fig. 2
