Abstract[English]
The present patent application describes a charger for electric vehicles that features a fault ride through capability, allowing it to use power from the vehicle's battery as a backup power source during low voltage faults of the grid. The charger includes a backup circuit that comprises a first coupling circuit connected to the power path of the electric vehicle battery through the charger, a second coupling circuit connected to the power path of the charger's power supply, and optionally a connection or conditioning circuit to match the voltages of the coupling circuits. The backup circuit enables the control and communication units of the charger to keep operating during low voltage faults of the grid, which can vary in duration from milliseconds to several seconds. The coupling circuits may be placed at various points in the charger's circuitry, such as the input, output, or internal points of the converter or power supply.[French]
La présente invention concerne un chargeur pour véhicules électriques qui dispose d'une capacité de tenue aux creux de tension, ce qui lui permet d'utiliser de l'énergie provenant de la batterie du véhicule en tant que source d'alimentation de secours pendant des défauts de basse tension du réseau électrique. Le chargeur comprend un circuit de secours qui comprend un premier circuit de couplage connecté au trajet de puissance de la batterie de véhicule électrique par l'intermédiaire du chargeur, un deuxième circuit de couplage connecté au trajet de puissance de l'alimentation électrique du chargeur, et facultativement un circuit de connexion ou de conditionnement pour assortir les tensions des circuits de couplage. Le circuit de secours permet aux unités de commande et de communication du chargeur de continuer à fonctionner pendant des défauts de basse tension du réseau électrique, qui peuvent varier en durée de quelques millisecondes à plusieurs secondes. Les circuits de couplage peuvent être placés en divers points dans les circuits du chargeur, tels que l'entrée, la sortie ou les points internes du convertisseur ou de l'alimentation électrique.
