摘要： A method of calibrating an offset of a pressure sensor, by which an offset of a sensing value of a pressure sensor, which detects a pressure of hydrogen in a fuel cell system, is accurately calibrated. The method includes receiving, by a controller, a sensing value of a pressure sensor which detects a hydrogen pressure in a state where a hydrogen supply starts after a start of a fuel cell system; counting, by the controller, a time for which the sensing value of the pressure sensor increases from a first pressure P1 to a second pressure P2; calculating, by the controller, an offset value corresponding to the counted time by use of stored setting data; and calibrating, by the controller, a subsequent sensing value of the pressure sensor by the calculated offset value in real time when the offset value is calculated.

摘要： An emergency start method for a fuel cell-powered vehicle includes starting the vehicle and detecting an abnormal state of a power supply system of an air blower upon the start of the vehicle. If the power supply system of the air blower is in the abnormal state, an air-check valve of a fuel cell opens. Hydrogen is supplied to the fuel cell, and the air blower operates with power generated from the fuel cell and an emergency start system.

摘要： A method and system for controlling a fuel cell vehicle are provided. The method includes determining, by a controller, a driving pattern of a driver based on driving information including acceleration and deceleration information. A condition for activation of an idling-stop of a fuel cell is then set based on the determined driving pattern and the fuel cell is stopped from generating electric energy when the condition for activation of the idling-stop is satisfied.

摘要： A method and apparatus for controlling charge of a low-voltage battery are provided. The method includes assigning, by a controller, a preset voltage for the low-voltage battery based on an operating mode of a vehicle and a charge state of a high-voltage battery. In addition, the controller compares the preset voltage with a present charge voltage of the low-voltage battery and increases the present charge voltage with a first slope until the present charge voltage becomes equal to the preset voltage when the preset voltage is greater than the present charge voltage. The operating mode comprises drive modes that include a first drive mode and a second drive mode, a fuel cell stop mode, and an emergency mode. The first drive mode is divided into a plurality of stages based on the charge state of the high-voltage battery.
