Hereinafter, the operation of the wireless power transmission system according to the embodiments of the present invention will be described. 9-11 are flow charts illustrating operation of a wireless power transmission system in accordance with embodiments of the present invention.

A wireless power application (700) is installed in the mobile device (200). Connects the wireless power receiver (300) to the mobile device (200). For example, the wireless power receiver 1 is connected to the mobile device 1 (S910), and the wireless power receiver 2 is connected to the mobile device 2 (S915).

Thereby forming a wireless communication channel between the mobile device 200 and the wireless power transmitter 400. [ For example, a wireless communication channel is established between the mobile device 1 (201) and the wireless power transmitter (S920), and a wireless communication channel is established between the mobile device (2) 202 and the wireless power transmitter (SS1020).

The wireless power transmitter 400 transmits wireless power transmitter identification information to one or more mobile devices located at a predetermined distance. For example, if the wireless power transmitter 400 transmits the first wireless power transmitter identification information to the mobile device 1 (S930) and the wireless power transmitter 400 transmits the wireless power transmitter identification information to the mobile device 2 (203) (S1030). The wireless power transmitter identification information received by the mobile device 200 is used to obtain an instruction to operate the wireless power transmitter from the wireless power service server 500. [ The wireless power service server 500 may not be connected between the wireless power transmitter 400 and the wireless power service server 500 so that the wireless power service server 500 may receive the wireless power from the mobile device 200 via the wireless power transmitter 400 ) Wireless power transmitter identification information. The wireless power transmitter identification information received from the mobile device 200 is distinguished from the wireless power transmitter identification information received directly from the wireless power transmitter 400. [

The mobile device 200 transmits the mobile device identification information, the wireless power transmitter identification information, and the wireless power transmitter identification information to the wireless power service server 500. For example, if mobile device 1 201 sends mobile device identification information, wireless power transmitter identification information, and wireless power transmitter identification information to wireless power service server 500 (S940) Transmits information on the mobile device identification information, the wireless power transmitter identification information, and the wireless power transmitter identification information to the service server 500 (S1040).

The mobile device 200 requests authentication from the wireless power service server 500 and the mobile device 200 receives authentication authorization information from the wireless power service server 500. [ For example, the mobile device 1 201 requests authentication from the wireless power service server 500 (S950), and receives the authentication approval information from the wireless power service server 500 (S955). The mobile device 2 202 requests the wireless power service server 500 for authentication (S1050), and receives the authentication approval information from the wireless power service server 500 (S1055). The mobile device 200 transmits the mobile device identification information upon authentication request. The mobile device identification information may include information about the mobile device and / or information about the user. The wireless power service server 500 compares the data stored in the server storage unit 530 and verifies its validity.

The wireless power service server 500 may send information about the predefined command to operate the wireless power transmitter 400 with the mobile device 200 and / or information about the predefined command to operate the wireless power receiver 300 send. For example, if the wireless power service server 500 receives information about a pre-set command to operate the wireless power transmitter 400 with the mobile device 1 201 and / or a pre-set command to operate the wireless power receiver 1 301 (S960), the wireless power service server 500 transmits information about the pre-set command and / or information about the wireless power receiver 2 (302) to operate the wireless power transmitter 400 with the mobile device 2 202 (Step S 1060).

The mobile device commands the wireless power transmitter 400 to cause the wireless power transmitter 400 to perform a predetermined operation. The wireless power transmitter 400 performs an operation according to a command received from the mobile device 1 (201), and performs an operation according to a command received from the mobile device 2 (202). For example, the mobile device 1 201 instructs the wireless power transmitter 400 to form a wireless power zone (S970). The wireless power transmitter 400 forms a wireless power zone (S975). The mobile device 1 201 commands the wireless power receiver 1 301 to receive power and / or charge the battery (S980). The wireless power receiver 1 301 turns on the wireless power receiving module and / or turns on the battery connector (S985), receives wireless power from the wireless power transmitter 400 (S990), and charges the battery (S995). 2, the wireless power transmitter 400 determines the size of the wireless power zone and the size of the wireless power zone based on the distance from the mobile device 1 201 and the wireless power reception status received from the mobile device 201 By controlling the intensity of the electromagnetic field, the power of the wireless power transmitter can be efficiently used.

The mobile device 2 202 instructs the wireless power transmitter 400 to form a wireless power zone (S1070). If multiple commands collide with each other, the wireless power transmitter 400 operates based on (i) the priority of a predetermined operation or (ii) the priority of a command received from a plurality of mobile devices 201, 202. In step S975, since the wireless power transmitter 400 already forms a wireless power zone, the wireless power transmitter 400 does not form a wireless power zone again, but controls the intensity of an electromagnetic field of the wireless power zone (S1075). 3, the wireless power transmitter 400 may determine the distance to the mobile device 2 202 and the wireless power reception state received from the mobile device 2 202, for example, by increasing the field strength of the wireless power zone, Based on the size of the wireless power zone and the strength of the electromagnetic field of the wireless power zone. Thereby, the power of the wireless power transmitter can be efficiently used. The mobile device 2 202 commands the wireless power receiver 2 302 to receive power and / or charge the battery (S1080). The wireless power receiver 1 301 turns on the wireless power receiving module and / or turns on the battery connector (S985), receives wireless power from the wireless power transmitter 400 (S1090), and charges the battery (S1095).

The mobile device 1 201 transmits the mobile device identification information, the wireless power transmitter identification information, and the charging completion information to the wireless power service server 500 when the user of the mobile device 1 charges the battery for a desired charging amount (S 1110) . The mobile device 1 (201) causes the wireless power receiver 1 (301) to turn off the wireless power receiving module and / or turn off the battery connector.

The mobile device 2 202 transmits the mobile device identification information, the wireless power transmitter identification information, and the charge completion information to the wireless power service server 500 when the user of the mobile device 2 charges the battery for a desired charge amount (S 1110) . Mobile device 2 202 causes wireless power receiver 2 302 to turn off the wireless power receiving module and / or turn off the battery connector.

When the mobile device 1 201 and / or the mobile device 202 move out of the wireless power zone, the wireless power transmitter 400 detects the event and stops the wireless power.

The wireless power service server 500 transmits the wireless charging charge information to the mobile device 1 201 in step S1120 and the wireless power service server 500 transmits wireless charging charge information to the mobile device 2 202 in step S1160 ). By allowing communication between the wireless power transmitter and the mobile device and communicating between the mobile device and the wireless power service server, there is no need for a separate wireless channel between the wireless power transmitter and the wireless power service server, There is an effect that additional services such as billing can be easily provided.

The mobile device 1 201 instructs to remove the wireless power zone (S1130). If multiple commands collide with each other, such as when mobile device 2 202 commands a wireless power zone or sends wireless power, wireless power transmitter 400 may (i) ) Operates on the basis of the priority order of the commands received from the plurality of mobile devices (201, 202). The wireless power transmitter 400 does not execute a command to remove the wireless power zone 450 received from the mobile device 1 201 because the wireless power transmitter 400 is transmitting wireless power to the wireless power receiver 302 in step S1090 . However, the wireless power transmitter 400 may adjust the size of the wireless power zone and the intensity of the electromagnetic field of the wireless power zone based on the distance to the mobile device 2 202 and the wireless power reception state received from the mobile device 2 202 . The mobile device 2 202 instructs the wireless power transmitter 400 to remove the wireless power zone (S1170). Since the command does not collide, the wireless power transmitter 400 removes the wireless power zone (S1180).

According to the wireless power transmission system, the mobile device instructs the wireless power transmitter to perform a predetermined operation of the wireless power transmitter, and the wireless power receiver connected to the mobile device commands the wireless power receiver to perform a predetermined operation, So that the user of the mobile terminal can control the wireless power transmission / reception process.
