Abstract
(EN)
The present invention relates to a system and a method for controlling a relay using a flip-flop, wherein a flip-flop, which receives a signal from a control unit and controls a relay, is installed in a battery management system of a vehicle, and flip-flop operating power is supplied to the flip-flop through a monitoring circuit connected to a battery of the vehicle, even when the operating power of the battery management system of the vehicle is cut off, thereby maintaining the closed state of the relay that controls the driving power of the vehicle and allowing the power of the vehicle to be preserved for a certain period of time.
(FR)
La présente invention concerne un système et un procédé de commande d'un relais à l'aide d'une bascule bistable. Selon l'invention, une bascule bistable qui reçoit un signal provenant d'une unité de commande et commande un relais, est installée dans un système de gestion de batterie d'un véhicule et une énergie de fonctionnement de bascule bistable est fournie à la bascule bistable par le biais d'un circuit de surveillance connecté à une batterie du véhicule, même lorsque l'énergie de fonctionnement du système de gestion de batterie du véhicule est déconnectée, ce qui maintient l'état fermé du relais qui commande l'énergie motrice du véhicule et permet à l'énergie du véhicule d'être préservée pendant une période donnée.
