The present invention relates to a method for preparing against the discharge of an electric latch assembly, which is able to, when the voltage of a battery decreases and there is a smart key in a vehicle, activate the electric latch assembly into a mechanical redundancy (MR) mode, and allow a door to be opened. According to the present invention, the method for preparing against the discharge of an electric latch assembly comprises: (S110) an unlock determination step to determine if the electric latch assembly (11) is unlocked by a control unit (30); a voltage monitoring step (S120) to start monitoring the voltage of a battery (20); (S130) a voltage comparison step to compare the voltage of the battery (20) with a preset reference voltage for activating the MR mode; and (S160) an MR activation step to, if the voltage of the battery (20) is lower than the reference voltage, drive an MR motor (11c) installed in the electric latch assembly (11), and activate the electric latch assembly (11) into the MR mode. 본 발명은 배터리의 전압이 낮아지고 차량의 내부에 스마트키가 있으면, 전동식래치 어셈블리를 MR모드로 활성화시켜 도어가 개방될 수 있도록 한 전동식래치 어셈블리의 방전 대비 방법에 관한 것이다. 본 발명에 따른 전동식래치 어셈블리의 방전 대비 방법은, 전동식래치 어셈블리(11)가 언락(unlock) 상태인지를 제어부(30)에 의해 판단되는 언락판단단계(S110); 배터리(20) 전압의 모니터링을 개시하는 전압모니터링단계(S120); 상기 배터리(20)의 전압을 MR(Mechanical Redundancy)모드를 활성화 하기로 미리 설정된 기준전압과 비교하는 전압비교단계(S130); 및 상기 배터리(20)의 전압이 상기 기준전압 이하이면, 상기 전동식래치 어셈블리(11)의 내부에 설치된 MR모터(11c)를 구동시켜 상기 전동식래치 어셈블리(11)를 MR모드로 활성화시키는 MR활성화단계(S160);를 포함한다.
