| 20090140690 | Wireless Power Charging System - A wireless power charging system has a wireless power transmission apparatus formed to charge a plurality of wireless power receiving apparatuses located in a short distance therefrom, wherein the total charging time for the wireless power receiving apparatuses is saved. The wireless power transmission apparatus has a main control unit and a resonant converter unit, which transmit the electric signal to the wireless power receiving apparatus via the resonance signal generated from a primary charge core in order to charge the wireless power receiving apparatuses. The wireless power transmission apparatus also includes an output signal conversion module for transmitting a converted electric signal to the resonant converter unit and a received signal process module for processing a signal transmitted from the wireless power receiving apparatus. | 06-04-2009 |
| 20090140691 | Wireless Multi-Charger System and Controlling Method Thereof - Disclosed are a wireless multi-charger system capable of saving the total charging time of a large number of wireless power transmission devices since one wireless multi-power transmission device includes a plurality of the wireless power transmission devices so that a large number of the wireless power transmission devices can be charged with electricity, and preventing the damage of the wireless power transmission devices and the wireless multi-power transmission device although foreign substances are put on charger blocks that are not charged. The wireless multi-charger system (A) according to the present invention includes an external body formed as a wireless charger case | 06-04-2009 |
| 20090206791 | Non-Contact Power Charging System and Control Method Thereof - 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. | 08-20-2009 |
| 20090267558 | Wireless Power Charging System - A non-contact power charging system includes a wireless power transmission apparatus | 10-29-2009 |
| 20100156343 | Wireless Charger System For Battery Pack Solution And Controlling Method Thereof - There is provided a wireless charger system for a battery pack solution that is provided so that a wireless charger system composed of a wireless charger apparatus and a battery pack can supply a power source to a portable terminal block through the wireless power transmission. The wireless charger apparatus | 06-24-2010 |
| 20100295505 | MOBILE TERMINALS AND BATTERY PACKS FOR MOBILE TERMINALS - Various embodiments of a battery pack, a mobile terminal having such a battery pack, and related methods are disclosed. In one exemplary embodiment, a battery pack for a mobile terminal may include a battery cell, a temperature sensor configured to measure a temperature of the battery cell, a charge detector configured to detect whether the battery cell is charged above a predetermined level, and a first connector terminal configured to electrically connect to the mobile terminal. | 11-25-2010 |
| 20110140538 | Non-Contact Power Transmission Apparatus - 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. | 06-16-2011 |
| 20110140653 | Non-Contact Charging Station with Power Transmission Planar Spiral Core, Non-Contact Power-Receiving Apparatus, and Method For Controlling the Same - 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. | 06-16-2011 |
