Abstract

Disclosed herein is a genuine product battery identification system for mobile devices. A tag for identifying whether a battery is a genuine product battery is included a battery, and a reader for transmitting and receiving radio frequency information is included in a mobile device body. When the battery is mounted in the mobile device body, the mobile device is operated with power supplied from the battery, and the genuine product battery identification system determines whether the battery is a genuine product battery through radio frequency. When it is determined that the battery is the genuine product battery, power is continuously received from the battery to the mobile device, by which the mobile device is normally operated. When it is determined that the battery is not the genuine product battery, on the other hand, the reception of power from the battery to the mobile device is interrupted, whereby problems caused due to the use of a non-genuine product battery are fundamentally solved.

Claims

1. A genuine product battery identification system for mobile devices, comprising:

a battery including a tag, which has an antenna for transmitting and receiving radio frequency, a database for storing product information, and a control unit for controlling the transmission and reception of information between the antenna and the database; and

a mobile device body including a reader, which has an antenna for transmitting and receiving radio frequency, a database for storing genuine product battery identification information, and a control unit for controlling the transmission and reception of information between the antenna and the database and controlling supply or interruption of power from the battery.

2. The system according to claim 1, wherein the mobile device body is a mobile phone, a camera, a personal digital assistant (PDA), or a laptop computer.

3. The system according to claim 1, wherein the battery is a lithium secondary battery.

4. The system according to claim 1, wherein the antenna of the battery is a loop-type antenna.

5. The system according to claim 4, wherein the loop-type antenna is integrally formed with a protection circuit module, which includes a protection circuit board and connecting terminals, by insert injection molding, while the loop-type antenna is electrically connected to the protection circuit module, so as to constitute a green-body cap assembly.

6. The system according to claim 4, wherein the loop-type antenna is mounted to the protection circuit board in the form of a chip, or is patterned on the protection circuit board.

7. The system according to claim 1, wherein the tag is a passive tag or an active tag.

8. The system according to claim 7, wherein the tag is the passive tag, and the device body further includes a wireless communication unit for transmitting power to the tag.

9. The system according to claim 1, wherein the tag and the reader further include an encoding and decoding unit for encoding and decoding information.

10. A method of operating the genuine product battery identification system according to claim 1, wherein

when the battery is mounted in the device body, the control unit of the device body transmits a radio frequency signal for requesting product information through the antenna so as to identify the product information of the battery;

the antenna of the tag receives the signal, and the control unit of the tag extracts product information stored in the database, modulates the extracted product information, and transmits the modulated product information to the device body through the antenna;

the received data signal is modulated into a signal that can be processed through the control unit of the device body, the control unit of the device body extracts information for genuine product battery identification stored in the database so as to determine whether the product information received from the battery corresponds to the extracted information for genuine product battery identification;

when it is determined that the battery is a genuine product battery, the system is set such that power can be continuously supplied from the battery, and, when it is determined that the battery is not a genuine product battery, the fact that the battery is not the genuine product battery is displayed in the form of video information or audio information, and the reception of power from the battery is interrupted.
