Aspects of the present invention relate to an apparatus and method for detecting foreign objects in a wireless power transmission system. This specification provides a wireless power reception apparatus for detecting foreign objects, including a power measurement unit for generating required power information indicative of required power for the wireless power reception apparatus, sending the required power information to a wireless power transmission apparatus, and measuring power induced from the wireless power transmission apparatus and a secondary coil for receiving the power induced from the wireless power transmission apparatus. In accordance with the present invention, foreign objects intervened between the wireless power transmission apparatus and the wireless power reception apparatus are recognized, and a user removes the foreign objects. Accordingly, damage to a device attributable to foreign objects can be prevented.

Apparatus and method for detecting foreign objects in wireless power transmission system

A non-contact power reception apparatus is provided, in which a power reception coil for a charging system and a loop antenna for an electronic settlement system are mounted on a battery pack and a cover case of a portable terminal such that the power reception coil is arranged in the center thereof and the loop antenna is disposed outside the power reception coil, so that a mode of receiving a wireless power signal and a mode of transmitting and receiving data are selectively performed, thereby preventing interference from harmonic components and enabling non-contact charging and electronic settlement using a single portable terminal. A jig for fabricating a core to be mounted to the non-contact power reception apparatus is provided.

Non-contact power reception apparatus for non-contact charging and electronic settlement performed in a single portable terminal

A wireless power reception device and a wireless communication method thereby are provided. The wireless communication method by the wireless power reception device may comprise the steps of: receiving a wireless power signal from a wireless power transmission device; measuring the strength of the wireless power signal; modulating the amplitude of the wireless power signal according to the measured strength of the wireless power signal; and performing communication with the wireless power transmission device by using the signal having the amplitude modulated.

Contactless power reception device and reception method

A non-contact power charging, in which power transmission can be interrupted when foreign materials are deposited on a charge plate of the non-contact power charging system. A charging operation can be continuously maintained at a stable voltage even if a non-contact power receiving apparatus moves by touching or displacement on the charge plate of the non-contact power charging system in the charging operation. Charging efficiency is improved.

Apparatus of non-contact power receiver utilizing transmission of a power adjustment request to a non-contact power transmitter

A non-contact power transmission apparatus accurately determines the kind of object that is placed on the charging deck of the non-contact power transmission apparatus, and, only when a non-contact power receiving apparatus is placed on the power transmission apparatus, allows power transmission and data communication to take place, thereby accurately determining the state of the receiver side and efficiently controlling the transmission of power. In the power transmission apparatus, the power supplied to the non-contact power receiving apparatus is measured, and the output power of the wireless power signal output from two different cores is controlled, thereby allowing the charging operation to be stably conducted even if the non-contact power receiving apparatus is moved anywhere on the power transmission apparatus. The power transmission apparatus improves both the reliability of operation of the non-contact charging system, and the competitiveness of related products, such as portable terminals, battery packs and the like.

Non-contact power receiver apparatus

Wireless power reception device and wireless communication method

The present disclosure provides a signal processing method performed by a hybrid wireless power transmitting apparatus which is configured to transmit wireless power signals based on magnetic resonance and magnetic induction, the method comprising transmitting a first object detection signal via an inductive power transmitting unit and a second object detection signal via a magnetic resonant power transmitting unit alternatively; operating one of the inductive power transmitting unit and the magnetic resonant power transmitting unit which is selected based on an inductive response signal and a resonant response signal corresponding to the first object detection signal and the second object detection signal respectively; and transmitting wireless power signal via the selected power transmitting unit; and a hybrid wireless power transmitting apparatus using the method.

Hybrid wireless power transmitting system and method therefor

Non-contact power transmission apparatus

A non-contact charging station with a planar-spiral power transmission core, a non-contact power-receiving apparatus, and a method for controlling the same. A primary core of the non-contact charging station transmitting a power signal to a portable device using an induced magnetic field and a secondary core of the non-contact power-receiving apparatus are configured as a power transmission Printed Circuit Board (PCB) core in which a planar-spiral core structure is formed on a core base. The power transmission PCB core has a simplified shape along with improved applicability that facilitates its mounting on a non-contact charger. In addition, the receiving core has a reduced volume to reduce the entire size of the power-receiving apparatus so that it can be easily mounted onto a portable device.
