Apparatus and method for early starting of vehicle

PURPOSE: An initial startup apparatus of vehicles and method may be started up by using energy applied from an energy storage part for a start motor. CONSTITUTION: An initial startup apparatus of vehicles comprises the converter (120), the control part (110), the energy storage part (130), the battery (150) and the start motor (160). Said converter is converted from a sleep mode to a wakeup mode in every given period, and the remaining amount of energy in an energy storage part and a battery is affirmed in said wakeup mode. Said control part controls the wakeup mode of said converter so as to apply energy of said energy storage part and battery to a startup motor according to the remaining amount of energy in said energy storage part and battery. Said energy storage part applies energy to a start motor based on control by said control part. Said battery applies energy to the start motor based on control by said control part. Said start motor is driven by application of energy in the sum of energy of said energy storage part and energy of the battery.
