An embodiment of the present invention provides a multiple wireless charging system for electric vehicles, which can reduce a leaked magnetic field between the chargers on the parking surfaces and can reduce an external influence due to the leaked magnetic field by giving a shielding function between wireless chargers having a wireless charging infrastructure installed on a plurality of parking surfaces. According to an embodiment of the present invention, the multiple wireless charging system for electric vehicles can include: an individual charging control device including a plurality of charging controllers each of which produces a plurality of high-frequency currents having a controlled phase based on a synchronizing signal provided in advance; wireless chargers each disposed on a plurality of the parking surfaces and including a plurality of wireless charging pads which send electric power by wireless according to the high-frequency current from each of the plurality of charging controllers; a plurality of mutual shielding members disposed between the plurality of parking surfaces and including a nonmagnetic material or a magnetic material to shield the leaked magnetic field between the plurality of wireless charging pads; and a plurality of individual shielding members spaced apart from each of the plurality of wireless charging pads at predetermined intervals, disposed on a lower portion and a side surface of each of the plurality of wireless charging pads, and including a nonmagnetic material or a magnetic material to shield the leaked magnetic field of each of the plurality of wireless charging pads.
