A control method for shortening a start time of an electric vehicle quickly removes electricity remaining in a system without adding a separate component. The control method includes comparing a DC-link voltage in an inverter for driving a driving motor with a first reference value in a state in which the connection between a main battery and a vehicle system is released; checking a remaining voltage in the vehicle system and comparing the checked remaining voltage with a second reference value, when the DC-link voltage in the inverter is no less than the first reference value; removing the remaining voltage by operating an electric load in the vehicle so as to consume remaining electricity in the vehicle system, when the remaining voltage is no less than the second reference value; and connecting the main battery to the vehicle system by turning on a pre-charge relay and a main relay.
