제어부에서 연료전지 스탑모드 진입을 체크하는 체크단계; 연료전지 스탑모드 진입시, 고전압배터리에서 충전이 가능한 전력의 정도를 나타내는 배터리가용충전전력에 기반하여 제어부에서 버스단 전압명령치를 산출하는 산출단계; 제어부에서 버스단의 전압이 버스단 전압명령치가 되도록 고전압배터리와 버스단의 사이에 연결된 컨버터를 제어하는 전압하강단계; 및 전압하강단계를 수행한 후 전압센서를 통해 측정된 연료전지의 전압이 메모리에 미리 설정된 기준전압 이상인 경우 제어부에서 차량 전장부하의 전력소모를 증가시키는 전력소모단계;를 포함하는 연료전지차량의 스탑모드시 전압 제어방법이 소개된다.

    A method and system for controlling a voltage in a stop-mode of a fuel cell vehicle are provided. The method includes detecting whether a fuel cell enters the stop-mode and calculating a voltage command value of a bus terminal based on available charging power of a battery representing a level of power chargeable in a high voltage battery when the fuel cell enters the stop-mode. A converter connected between the high voltage battery and the bus terminal is operated to adjust the voltage of the bus terminal to be the voltage command value of the bus terminal. Additionally, power consumption of an electric field load of a vehicle is increased when the voltage is adjusted and then the voltage of the fuel cell measured by a voltage sensor is equal to or greater than a reference voltage preset in a memory.
