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.

摘要： A system and method for emergency starting of a fuel cell vehicle is provided. In particular, a high-voltage converter, a balance of power (BOP), and a controller are included in the system. The high-voltage converter is configured such that one side thereof is connected to a high-voltage battery via a battery switch and the other side thereof is connected in parallel to a plurality of fuel cells. The BOP is connected in parallel to the high-voltage converter and the fuel cells. The controller is configured to control the power supplied from the high-voltage battery to the BOP without conversion by connecting the battery switch upon the failure of the high-voltage converter or high-voltage battery.
