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 charge a battery 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 coil(110) and a transmission controller(120). The primary coil transmits a power signal to a secondary core(210) of a wireless power reception device(200) in an electromagnetic induction method. An AC/DC inverter(130) converts an AC power supply of 220V or 110V into a DC power supply of a predetermined voltage. The wireless power reception device includes a secondary side coil, a rectifier(220), a battery cell module(230) and a reception controller(240). The rectifier rectifies wireless power received from the secondary coil into a DC voltage.
