Description

TECHNICAL FIELD [0001] The present invention relates to a charging method and a charging system for wireless charging of a portable terminal,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a charging method and a billing system for wireless charging of a portable mobile terminal, and more particularly to a method and system for charging for charging the portable mobile terminal wirelessly through a wireless charger.

BACKGROUND ART A mobile terminal such as a mobile phone or a PDA (Personal Digital Assistants) is driven by a rechargeable battery. In order to charge the battery, a separate charging device is used to supply electric energy to the battery of the mobile terminal. Typically, the charging device and the battery are each provided with a separate contact terminal on the outside thereof, thereby electrically connecting the charging device and the battery by making them contact each other.

However, in such a contact type charging method, since the contact terminal protrudes to the outside, contamination by foreign matter is easy and the battery charging is not properly performed. Also, even if the contact terminals are exposed to moisture, charging is not properly performed.

In order to solve these problems, wireless charging or non-contact charging technology has recently been developed and used in many electronic devices.

This wireless charging technique uses wireless power transmission and reception, for example, a system in which a battery can be automatically charged by simply placing a cellular phone on a charging pad without connecting a separate charging connector. It is generally known to the general public as a wireless electric toothbrush or a wireless electric shaver. Such wireless charging technology can enhance the waterproof function by charging the electronic products wirelessly, and it is advantageous to increase the portability of the electronic devices since the wired charger is not required, and the related technology is expected to greatly develop in the upcoming electric car era .

Such wireless charging techniques include an electromagnetic induction method using a coil, a resonance method using resonance, and a radio frequency (RF) / microwave radiation (RF) method in which electric energy is converted into a microwave.

Currently, electromagnetic induction is the main method. However, in recent years, experiments have been successfully conducted to transmit electric power wirelessly from a distance of several tens of meters using microwaves at home and abroad. In the near future, The world seems to be opened.

The power transmission method by electromagnetic induction is a method of transmitting power between the primary coil and the secondary coil. When a magnet is moved to a coil, an induced current is generated, which generates a magnetic field at the transmitting end and induces a current according to the change of the magnetic field at the receiving end to generate energy. This phenomenon is called magnetic induction phenomenon, and the power transmission method using the phenomenon is excellent in energy transmission efficiency.

The electromagnetic induction method is applied to various devices in a way that has the most practical use. BACKGROUND ART [0002] In the conventional solid state charging technology called wireless charging, electromagnetic induction methods are the majority, and this method is applied to products such as electric razors and electric toothbrushes using nickel batteries.

In 2005, Professor Soljacic of MIT announced Coupled Mode Theory, a system in which electricity is delivered wirelessly, even at distances of a few meters (m) from the charging device, using resonant power transmission principles. The MIT team's wireless charging system uses resonance (resonance), which uses a physics concept that resonates at the same frequency as a wine bottle next to the tuning fork. Instead of resonating the sound, the researchers resonated electromagnetic waves that contained electrical energy. The resonant electrical energy is transmitted directly only when there is a device with a resonant frequency, and unused portions are not re-absorbed into the air, but are reabsorbed into the electromagnetic field. Therefore, unlike other electromagnetic waves, they will not affect the surrounding machine or body .

The radio wave radiation system is a new concept of power transmission system that converts energy into microwave which is advantageous for wireless transmission and transfers energy. The concept of a signal used in a wireless communication system such as a radio or a wireless telephone is not a concept of a signal, but an electric energy is transmitted. When a normal communication transmits a signal to a carrier wave, a wireless power transmission is a system in which only a carrier wave is transmitted.

Conventional wireless charging techniques have been limited to electric shavers and electric toothbrushes. Recently, resonance methods have been developed and much research has been conducted to introduce wireless charging technology into mobile phones and TVs. Accordingly, a method of assisting power charging between devices capable of supplying electric power to each other when necessary is being studied.

With the commercialization of such wireless charging technology, a wireless charger is installed in a place such as a famous coffee shop, and a charging method for such a wireless charger becomes an issue.
