Abstract

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 ina 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 powerof 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 bepreserved for a certain period of time.

Description

technical field [0001] This application claims priority and benefit from Korean Patent Application No. 10-2018-0115723 filed with the Korean Intellectual Property Office on September 28, 2018, the entire contents of which are incorporated herein by reference. [0002] The present invention relates to a system and method for controlling a relay using a flip-flop, and in particular, to a system and method for controlling a relay using a flip-flop installed in a battery management system of a receiving vehicle The trigger of the relay is controlled by the signal of the control unit of the vehicle, and even when the operating power of the battery management system of the vehicle is interrupted, the trigger operating power is supplied to the trigger through the monitoring circuit connected to the vehicle's battery to maintain control of the vehicle The closed state of the relay of the drive power and maintain the power of the vehicle for a predetermined time.
