PURPOSE: A power reception control method in a wireless power reception device, and the wireless power reception device applying the same are provided to stably operates an electronic device connected to the wireless power reception device by softly lowering a charging voltage to a set voltage and set current when a load connection event is occurred. CONSTITUTION: A wireless power transmission device includes a primary side core(110), a transmission controller(120), and an AC/DC converter(130). The primary side core includes a first subsidiary coil(111) and a second subsidiary coil(112). The AC/DC inverter converts an AC power supply into a DC power supply of a predetermined voltage. A wireless power reception device(200) includes a secondary side core(210), a rectifier(220), a battery cell module(230), and a reception controller(240). The secondary side core receives a wireless power signal transmitted from the primary side core of the wireless power transmission device.
