Electric power generation system of electric vehicle

A power generation control system of an electric vehicle is disclosed. The power generation control system of an electric vehicle is characterized in that an elastic recovery force of a spring is converted into a rotational energy via a spring power generation apparatus (1000), and the output of converted rotational energy is geared up for driving a vehicle generator (600) and generating electric energy, and when the spring is unwound, the auto winding operation of the spring is performed by means of a spring winding motor (900) with the help of control of a control unit (4000), and when a battery (700) is over charged by means of the power generation process, the operation of the spring power generation apparatus is stopped.
