PURPOSE: A system and method for supplying power to an electric vehicle of a noncontact electromagnetic inductive charging method are provided to extend the lifetime of a battery by charging a battery with a constant voltage. CONSTITUTION: A pickup module(20) collects AC power from a feeding line(10) buried in a road with AC power. A regulator(30) changes AC power into DC power. A DC-DC converter(40) converts instable DC voltage into a constant voltage and supplies the DC voltage to a driving motor(50). The DC-DC converter supplies surplus power to a battery(60) or super capacitor(70). The driving motor stably drives an electric vehicle by using the constant voltage received from the DC-DC converter.
