Abstract: PURPOSE: A method for controlling an output voltage of a DC-DC converter for a hybrid vehicle is provided to increase an output voltage of the DC-DC converter when the temperature of external air is low, thereby increasing charging performance of a sub battery. CONSTITUTION: If the starting of a vehicle is turned on, it is determined whether the temperature(Tx) of external air is lower than a boundary temperature(Tx1). If the temperature of external air is higher than the boundary temperature, a DC-DC converter normally operates. If the temperature of external air is lower than the boundary temperature, a voltage of an output terminal or a sub battery of the DC-DC converter is measured to select a driving mode of the vehicle. If a voltage of the output terminal of the DC-DC converter or a voltage of a 12V sub battery is lower than a fixed voltage, the vehicle operates in a strong charging mode. If a voltage of the output terminal of the DC-DC converter or a voltage of the 12V sub battery is higher than a fixed voltage, the vehicle operates in a weak charging mode.

Abstract: A method for diagnosing a defect of a DC-DC converter of an electric vehicle is provided to lengthen durability of the DC-DC converter and an auxiliary battery in a hybrid/fuel cell vehicle by diagnosing rapidly the defect of the DC-DC converter. A low-voltage DC-DC converter outputs a voltage according to a voltage command received from an external controller and monitors simultaneously an output voltage. The voltage command and the real output voltage are compared with each other in order to diagnose a defective state of a DC-DC converter. When a difference between the voltage command and the real output voltage exceeds a reference voltage and the exceeding time of the reference voltage is maintain during a constant period, the defective state is diagnosed. The low-voltage DC-DC converter generates a defective diagnosis code and turns on an alarm lamp.
