Induced electromotive force is generated in the secondary side core 51 provided in (B) and the like so as to be used as a power source.

Accordingly, the primary side core 33 may be provided to generate a charging induction magnetic field in each of the battery packs B. In an embodiment of the present invention, the primary core 33 may be a circular spiral coil, an uncore core, a rectangular spiral coil, or a winding core. It may be provided as a coil or the like. However, the present invention is not limited thereto, and may be provided in various forms to generate an induction magnetic field capable of transmitting power to the battery pack.

The battery pack B of the present invention converts the induced electromotive force generated in the secondary side core 51 by the induced magnetic field generated by the primary side core 33 of the wireless power charging station A.
