The present invention relates to power supply apparatus for prevention of a vehicle fire. According to the present invention, the conventional vehicle having a main power supply means is additionally equipped with a fire prevention means and an auxiliary power supply means. The present power supply apparatus detects the main power voltage of the vehicle and vehicle collision in the process of operating, and determines whether the main power voltage at the time of a vehicle collision and an electric short-circuit accident is lower than a voltage set in advance. If the main power voltage is determined to be lower, the present apparatus intercepts the main power supply to prevent a fire caused by the electric short-circuit. If the main power supply is intercepted, the present apparatus provides an auxiliary power supply to the devices necessary for safe driving, for example, the brake, power handle, and emergency lamp. |
