Abstract: An active energy repeater is provided. The active energy repeater comprises a transceiving antenna receiving power from a wireless power transmission device and transmitting the power to a wireless charging device; a relay antenna relaying the power received from the wireless power transmission device to the wireless charging device; a magnetic field communication modem performing magnetic field communication with the wireless charging device by using a magnetic field communication protocol; a control unit controlling transmission, reception, storage, and relay of the wireless power; and a battery charging the power received from the wireless power transmission device. The active energy repeater obtains information of the wireless charging device by communicating with the wireless charging device using a magnetic field communication. The active energy repeater reduces the energy use in time when the energy density and a user's magnetic energy exposure time is high by storing the power when the user density is low and retransmitting the energy to a device from the active energy repeater during the time when the user's density is high, thereby improving stability. The active energy repeater also reduces the burden of power control for each wireless charging device to perform integral control in the wireless power transmission device by having a communication function for the control.
