Title (EN) BIDIRECTIONAL ENERGY-CONVERSION APPARATUS OF A DC-DC TYPE OPERATING BETWEEN A LOW-VOLTAGE SYSTEM AND A HIGH-VOLTAGE SYSTEM OF A VEHICLE COMPRISING AN ENERGY-RECOVERY STAGE, AND CORRESPONDING METHOD
(FR) APPAREIL BIDIRECTIONNEL DE CONVERSION D'ÉNERGIE CC-CC FONCTIONNANT ENTRE UN SYSTÈME BASSE TENSION ET UN SYSTÈME HAUTE TENSION D'UN VÉHICULE COMPRENANT UN ÉTAGE DE RÉCUPÉRATION D'ÉNERGIE, ET PROCÉDÉ CORRESPONDANT
Abstract:
(EN) A bidirectional energy-conversion apparatus of a DC-DC type operating between a low-voltage system (LV) and a high-voltage system (HV) of a vehicle comprising an energy-recovery stage (30), said low-voltage system (LV), which operates at a first voltage (Vbat), comprising a battery (14) that supplies said first voltage (Vbat) on a low-voltage bus (LV), said high-voltage system (HV), which operates at a second voltage (VinDCDC, VDClink) higher than said first voltage (Vbat), comprising said energy-recovery stage (30) of the vehicle that supplies said second voltage (VinDCDC; VDClink), said second voltage (VinDCDC, VDClink) being supplied through an intermediate energy-storage system (40) to a DC-DC conversion module (23; 123), which converts said second voltage (VinDCDC, VDClink) into said first voltage (Vbat) for said low-voltage bus (LV). The aforesaid DC-DC conversion module (123) comprises a bidirectional DC-DC converter (124) connected between the intermediate energy-storage stage (40) and the vehicle battery (14). Said apparatus is configured for selecting a direction of conversion of said bidirectional converter (124), from high voltage (HV) to low voltage (LV) or from low voltage (LV) to high voltage (HV) via a control circuit (140) as a function of the value of the voltage (VDClink) on the high-voltage bus (HV).
(FR) L'invention concerne un appareil bidirectionnel de conversion d'énergie CC-CC, qui fonctionne entre un système basse tension (LV) et un système haute tension (HV) d'un véhicule comprenant un étage de récupération d'énergie (30). Ledit système basse tension (LV), qui fonctionne à une première tension (Vbat), comprend une batterie (14) qui fournit ladite première tension (Vbat) sur un bus basse tension (LV). Ledit système haute tension (HV), qui fonctionne à une seconde tension (VinDCDC, VDClink) supérieure à ladite première tension (Vbat), comprend ledit étage de récupération d'énergie (30) du véhicule qui fournit ladite seconde tension (VinDCDC, VDClink), ladite seconde tension (VinDCDC, VDClink) étant fournie par l'intermédiaire d'un système intermédiaire de stockage d'énergie (40) à un module de conversion CC-CC (23, 123), qui convertit ladite seconde tension (VinDCDC, VDClink) en ladite première tension (Vbat) pour ledit bus basse tension (LV). Le module de conversion CC-CC (123) précité comprend un convertisseur CC-CC bidirectionnel (124) branché entre l'étage de stockage d'énergie intermédiaire (40) et la batterie de véhicule (14). Ledit appareil est configuré pour sélectionner une direction de conversion dudit convertisseur bidirectionnel (124), de haute tension (HV) à basse tension (LV) ou de basse tension (LV) à haute tension (HV), par l'intermédiaire d'un circuit de commande (140) en fonction de la valeur de la tension (VDClink) sur le bus haute tension (HV).
