Description

[Correction 28.03.2018 by Rule 26] 충전 Wireless Charging Application System

The present invention relates to wireless charging of a personal smart device, and more particularly, when a user using a personal smart device charges a wireless charger of a wireless charging method using a dedicated application, the best charging between the wireless charger and the personal smart device. The present invention relates to a wireless charging application system that allows a user to intuitively show efficient contact points so that the contact points between the wireless charger and the personal smart device can be modified.

In general, a method of charging a device by transmitting power wirelessly through the air instead of a method of charging a device by transmitting power over an existing wire is called wireless charging. There are three types of wireless charging methods: magnetic induction, magnetic resonance (electromagnetic resonance), and electromagnetic wave. Generally, the wireless charging method is divided into magnetic induction and resonance. The difference between the two methods is largely divided into contact between the terminal and the charger. All currently available wireless charging technologies are self-induction and support the 'Qi' standard of the Wireless Power Consortium (WPC), one of the wireless charging technologies.

First, inductive charging is a technique using an electromagnetic induction principle in which a magnetic field is generated in a power transmitter coil to induce a secondary coil to supply a current. This is possible only when the coil is located in close proximity. The magnetic induction method has a very high power transmission efficiency of more than 90%, but there is a problem that the efficiency is sharply deteriorated so that almost no power is transmitted if it is more than a few centimeters apart or if the centers of the transmitting coil and the receiving coil do not coincide exactly. . It doesn't just connect to an outlet, it's just like wired charging. Resonant inductive coupling is a principle of resonant induction, in which a magnetic field oscillates at a resonant frequency in a transmitter coil so that energy is concentrated only at a receiver coil designed at the same resonant frequency. That is, it is a technology that transmits power by performing magnetic resonance using frequencies of several MHz to tens of MHz band.

Energy can be transmitted at a higher efficiency than a magnetic induction method, and in the case of a resonance method, power can be transmitted at a efficiency of about 40% even at 2M with a high efficiency of about 90% at a distance of about 1M. Energy that is not absorbed by the receiver coil is radiated into the air and is not absorbed, but is absorbed by the transmitter coil again.

However, a problem arises in that the transmission distance and efficiency are deteriorated in the actual use environment. The smaller the frequency band at which the transmitter and receiver cause resonance, the farther the efficiency can be transmitted, and the quality factor (Q factor) of the resonator must be kept high. If the signal is not properly captured, it may cause heat problems and it should be proved that the power transmitted wirelessly is not harmful to the human body. Currently, no international standard for resonant method is an obstacle to commercialization.

Meanwhile, with the development of information and communication technology, various kinds of services are provided to users who use personal smart devices. In recent years, due to the rapid increase in the number of users using personal smart devices, efforts have been made to provide various services using dedicated applications developed by individuals or companies.

Since personal smart devices generally have numerous applications and various devices, power consumption has explosively increased compared to conventional personal terminals, so users who usually use personal smart devices have one or more auxiliary or portable batteries. There is a need to charge frequently. Therefore, services for charging personal smart devices are also being performed at convenience stores or restaurants.

Conventionally, in order to cope with such a situation, users of personal smart devices carry a charging adapter or purchase a separate mobile phone battery in addition to a spare portable battery manufactured by a personal smart device manufacturer.

However, it is difficult to clarify the responsibility material when it is lost or damaged if it is left unowned for a certain period of time to charge a personal smart device, and recently, intentional theft has been caused by unscrupulous people. Smart device users have a problem that important personal information is leaked and the cost burden is increased due to the repurchase of personal smart devices. In particular, smartphones with high sales prices usually have loss insurance, so mobile carriers or insurance companies are at risk. There was a problem that the operating margin is reduced.

Prior art related to the system for charging such a personal smart device using a wireless as the primary coil arrangement and charging consisting of a plurality of coils mounted in the charging plate in Korea Patent Publication No. 10-2012-0103309 The charging power is supplied by using induction electromotive force between the secondary coil arrays composed of a plurality of coils mounted in the target device, and the shape, size and arrangement of each coil, and the mutual position of the primary coil array and the secondary coil array Therefore, the power delivery state is changed to allow the device to be charged to be charged normally at an arbitrary position on the charging plate without the accurate position alignment between the primary coil array and the secondary coil array, and multiple devices are randomly mounted on the same charging plate.
