A stable power supply device for a high voltage battery system in a vehicle enables the voltage of a capacitor in a high voltage component to be gradually increased at an initial stage of ignition, using a heat generating resistor of a temperature raising system mounted to raise the temperature of a battery in the vehicle. Further, the stable power supply device enables a capacitor in a high voltage component to be discharged using a heat generating resistor of a temperature raising system after the ignition of the vehicle is off, thereby ensuring the stability of the system.
