Title (EN) 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 DE CONVERSION D'ÉNERGIE DE TYPE 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) An 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), said apparatus (90; 190) comprising an auxiliary load (Raux), in particular an external load, which can be connected in order to enable dissipation of the excess energy supplied by the energy-recovery system (30). Said DC-DC conversion module (123) comprises a first bidirectional DC-DC converter (124) connected between the intermediate energy-storage stage (40) and the vehicle battery (14), and a second DC-DC converter (125) connected between the intermediate energy-storage stage (40) and said auxiliary load (Raux) ·
(FR) L'invention concerne un appareil de conversion d'énergie de type CC-CC fonctionnant 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 de stockage d'énergie intermédiaire (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). Ledit appareil (90; 190) comprend une charge auxiliaire (Raux), en particulier une charge externe, qui peut être connectée afin de permettre la dissipation de l'énergie excédentaire fournie par le système de récupération d'énergie (30). Ledit module de conversion CC-CC (123) comprend un premier convertisseur bidirectionnel CC-CC (124) connecté entre l'étage de stockage d'énergie intermédiaire (40) et la batterie de véhicule (14), et un second convertisseur CC-CC (125) connecté entre l'étage de stockage d'énergie intermédiaire (40) et ladite charge auxiliaire (Raux).
