Abstract:
1. A non-contact charging station for generating an induced magnetic field toward a non-contact power-receiving apparatus for power charge, the non-contact charging station comprising: a transmission controller provided inside the non-contact charging station, for controlling power transmission and data transmission; a station part including a primary core, for generating the induced magnetic field, and placing the non-contact power-receiving apparatus on top thereof, wherein the primary core is configured in a multi-layered structure and includes a single central core in an upper layer and two side cores in a lower layer, wherein the single central core and two side cores transmit first signals respectively to the non-contact power-receiving apparatus in a standby mode; a received signal processor connected to the primary core to receive, in response to the first signals, at least one response signal indicating received signal intensity of the first signals, from the non-contact power-receiving apparatus; and a shield panel disposed bottom in the primary core, for shielding a magnetic field radiating from the primary core, wherein the central core is placed in a position between the two side cores and is partially overlapped with each of the two side cores, wherein the transmission controller selects, at least one of the central core and the two side cores based on the received signal intensity of the first signals in the standby mode, wherein the transmission controller controls a power signal to be transmitted by the at least one selected core in a charging mode, wherein the non-contact charging station receives a second signal including information regarding a degree of voltage calibration for the power signal from the non-contact power-receiving apparatus in the charging mode, transmits a compensated power signal according to the signal including the information regarding the degree of voltage calibration for the power signal to the non-contact power-receiving apparatus in the charging mode, and stops the power transmission if it is detected that a metallic body other than the non-contact power-receiving apparatus is placed on the station part, and wherein the at least one selected core has the best received signal intensity among the single central core and the two side cores.
