Abstract
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.
