Description

Method and Apparatus for Transmitting a Wireless Power

Various embodiments of the present invention relate to a method and device for wireless power transmission.

Mobile devices like mobile phones, by their very nature, are powered by rechargeable batteries. To recharge these batteries, a separate charging device must be used to supply electrical energy. Typically, the charging device and battery each have separate contact terminals, which are brought into contact to electrically connect the two.

However, this type of contact-based charging method has problems, such as the contact terminals protruding from the outside, making them susceptible to contamination by foreign substances, potentially preventing proper battery charging. Furthermore, charging may not be performed properly if the contact terminals are exposed to moisture.

To solve these problems, wireless charging or contactless charging technology has been developed recently and is being used in many electronic devices.

This wireless charging technology utilizes wireless power transmission and reception. For example, a mobile phone can automatically charge its battery simply by placing it on a charging pad, without the need for a separate charging connector. This wireless charging technology is commonly used in wireless electric toothbrushes and electric shavers, and is well-known to the general public. This wireless charging technology can enhance waterproofing by wirelessly charging electronic devices, and it also increases the portability of electronic devices by eliminating the need for a wired charger. It is expected that related technologies will continue to advance significantly in the upcoming era of electric vehicles.

These wireless charging technologies can be broadly categorized into electromagnetic induction, resonance, and RF/Micro Wave Radiation, which converts electrical energy into electromagnetic waves to transmit power over long distances.

Although electromagnetic induction has been the mainstream method to date, recent experiments using electromagnetic waves to wirelessly transmit power over distances of tens of meters have been successful both domestically and internationally, and it seems that in the near future, a world will open where all electronic devices can be charged wirelessly, without wires, anytime, anywhere.

Power transmission via electromagnetic induction involves transferring power between a primary coil and a secondary coil. When current flows through the primary coil in the transmitter, a magnetic field is generated around it. This change in magnetic field induces a current in the secondary coil in the receiver. This phenomenon, known as magnetic induction, allows for power transmission methods utilizing it to achieve high energy transfer efficiency.

The resonance method was announced in 2005 by Professor Soljacic of MIT using the Coupled Mode Theory to wirelessly transfer power even when the charging device is several meters away. Instead of resonating sound, the MIT research team resonated electromagnetic waves containing electrical energy. The resonated electrical energy is directly transmitted only when a device with the resonant frequency is present, and the unused portion is reabsorbed into the electromagnetic field instead of being dispersed into the air. Therefore, unlike other electromagnetic waves, it is expected to have no effect on nearby machines or bodies.

Meanwhile, this wireless charging technology offers the advantage of being able to charge multiple wireless power receivers simultaneously because it doesn't use wires. However, if multiple wireless power receivers indiscriminately request wireless power, efficiency can drop, requiring careful management. Furthermore, for commercial use, power must be supplied only to certified wireless power receivers.

FIG. 4 illustrates a wireless charging system using a wireless power transmission device using an electromagnetic wave method according to an embodiment of the present disclosure.

Referring to FIG. 4, a wireless power transmitter (100), a wireless power receiver (200), an NFC tag (210), and a server (300) are illustrated.

A wireless power transmitter (100) can wirelessly transmit power to at least one wireless power receiver (200). The wireless power transmitter (100) can include a plurality of patch antennas (111 to 126). Each of the patch antennas (111 to 126) can generate electromagnetic waves. At least one of the amplitude and phase of the electromagnetic waves generated by the patch antennas (111 to 126) can be adjusted by the wireless power transmitter (100). For convenience of explanation, the electromagnetic waves generated by each of the patch antennas (111 to 126) will be referred to as sub-electromagnetic waves.

The wireless power transmission device (100) can adjust at least one of the amplitude and phase of each sub-electromagnetic wave generated from the patch antennas (111 to 126). Meanwhile, the sub-electromagnetic waves may interfere with each other. For example, at one point, the sub-electromagnetic waves may constructively interfere with each other, and at another point, the sub-electromagnetic waves may destructively interfere with each other.

The wireless power transmission device (100) can adjust at least one of the amplitude and phase of each of the sub-electromagnetic waves radiated by the patch antennas (111 to 126) so that the sub-electromagnetic waves can constructively interfere with each other at the first point (x1, y1, z1).

The wireless power receiver (200) may obtain location information related to a wireless charging area included in the tag device by bringing the wireless power receiver (200) into proximity or contact with an NFC tag (210) to receive wireless power from the wireless power transmitter (100). When the NFC tag (210) is located at a first point (x1, y1, z1), the tag device may include location information of the first point, an NFC tag ID, an IP address of the wireless power transmitter (100), and connection information of a server to be connected, as described above with reference to FIG. 1. Here, the location information of the first point may include an area within a certain distance from the first point and may be location information related to the wireless charging area. In addition, the location information of the first point may include an ID of the charging area. If the location information is an ID of a charging area, conditions for transmitting wireless power (e.g., direction, distance, coordinates, phase and amplitude of electromagnetic waves, etc.) corresponding to the charging area ID may be stored in advance in the wireless power transmitter (200) or server (300). That is, the wireless power transmitter (100) that receives the charging area ID from the wireless power receiver (200) can transmit wireless power to the wireless power receiver (200) using the conditions corresponding to the received charging area ID.

When a user brings the wireless power receiver (200) close to or into contact with an NFC tag, the wireless power receiver (200) can obtain information contained in the NFC tag.

That is, the wireless power receiver (200) can obtain location information (e.g., coordinates) of the first point (x1, y1, z1) and communication setting information such as the IP address of the wireless power transmitter (100) to establish communication with the wireless power transmitter (100). The location information of the first point may be location information related to a wireless charging area.

Depending on the embodiment, the NFC tag may be replaced with a QR code or an RFID tag, and the wireless power receiver (200) may acquire location information of the first point and communication setting information of the wireless power transmitter (100) through the QR code or RFID tag. The wireless power receiver (200) may capture a QR code using a camera, and may acquire location information of the first point (location information related to the wireless charging area) and communication setting information of the wireless power transmitter (100) through the captured QR code.

The wireless power receiver (200) uses communication setting information to establish communication between the wireless power transmitter (100) and the wireless power receiver (200) and transmits location information related to the wireless charging area to the wireless power transmitter (100). The wireless power receiver (200) can use the communication setting information to perform communication necessary for wireless power reception with the wireless power transmitter (100).

The wireless power transmitter (100) can transmit wireless power (400) using location information related to a wireless charging area received from the wireless power receiver (200). For example, when transmitting wireless power using an electromagnetic wave method, the wireless power transmitter (100) can transmit wireless power (400) to the wireless power receiver (200) by controlling at least one of the phase and amplitude of each sub-electromagnetic wave based on the location information related to a wireless charging area received from the wireless power receiver (200).

In order for the wireless power receiver (200) to receive wireless power with high efficiency, the sub-electromagnetic waves must constructively interfere with each other at the first point (x1, y1, z1) where the wireless power receiver (200) is placed for charging. Accordingly, the wireless power transmitter (100) can control the patch antennas (111 to 126) so that the sub-electromagnetic waves constructively interfere with each other at the first point (x1, y1, z1). Here, controlling the patch antennas (111 to 126) may mean controlling the magnitude of the signal input to the patch antennas (111 to 126) or controlling the phase (or delay) of the signal input to the patch antennas (111 to 126).

Meanwhile, beamforming, a technology that controls electromagnetic waves to constructively interfere at a specific point, will be readily understood by those skilled in the art. Furthermore, it will also be readily understood by those skilled in the art that there is no limitation on the type of beamforming used in the present invention. For example, various beamforming methods, such as those disclosed in U.S. Patent Publication No. 2016/0099611, U.S. Patent Publication No. 2016/0099755, and U.S. Patent Publication No. 2016/0100124, may be utilized. The shape of the electromagnetic waves formed by beamforming may also be referred to as "pockets of energy."

Accordingly, the electromagnetic wave formed by the sub-electromagnetic waves can have a maximum amplitude at the first point (x1, y1, z1), so that the wireless power receiving device (200) can receive wireless power (400) with high efficiency.

More specifically, when the wireless power receiver (200) is disposed relatively to the right with respect to the wireless power transmitter (100), the wireless power transmitter (100) can apply a relatively larger delay to sub-electromagnetic waves formed from patch antennas (e.g., 114, 118, 122, 126) disposed relatively to the right among the plurality of patch antennas constituting the array antenna of the wireless power transmitter (100). That is, after the sub-electromagnetic waves formed from the patch antennas disposed relatively to the left (e.g., 111, 115, 119, 123) are formed first, sub-electromagnetic waves can be generated from the patch antennas disposed relatively to the right (e.g., 114, 118, 122, 126) after a predetermined period of time has elapsed. Accordingly, the sub-electromagnetic waves can simultaneously meet at the relatively right point, and thus the sub-electromagnetic waves can constructively interfere at the relatively right point. If beam-forming is performed to transmit wireless power (400) to a wireless power receiver (200) located at a relatively central point based on a wireless power transmitter (100), the wireless power transmitter (100) can transmit wireless power (400) to the wireless power receiver (200) by radiating sub-electromagnetic waves generated by applying substantially the same delay to patch antennas located on the left side of the array antenna (e.g., 111, 115, 119, 123) and patch antennas located on the right side (e.g., 114, 118, 122, 126). In addition, when beam-forming is performed to transmit wireless power (400) to a wireless power receiving device (200) located at a point relatively to the left of a wireless power transmitter (100), a larger delay can be applied to patch antennas (e.g., 111, 115, 119, 123) located on the left side of the array antenna of the wireless power transmitter (100) than to patch antennas (e.g., 114, 118, 122, 126) located on the right side.

As described above, the wireless power transmitter (100) determines a location where wireless power should be transmitted using the NFC tag (210) information transmitted by the wireless power receiver (200), and causes sub-electromagnetic waves to generate constructive interference at the determined location, thereby performing wireless charging with high transmission efficiency. That is, the wireless power transmitter (100) can control the phase and amplitude of the electromagnetic waves radiated through the patch antenna based on the location information of the first point.

FIG. 5 illustrates an example of a wireless charging system using a plurality of electromagnetic wave wireless power transmission devices according to an embodiment of the present disclosure.

Referring to FIG. 5, a wireless charging system is illustrated with a plurality of wireless power transmitters (100, 103, 105), a plurality of wireless charging tables (211, 213, 215), a server (300), and a wireless power receiver (200).

For convenience of explanation, it is assumed that a wireless power receiving device (200) such as a mobile terminal enters a wireless charging system. The first wireless power transmitting device (100) corresponds to a first wireless charging table (211). A first NFC tag (211a) may be attached to the first wireless charging table (211), and the first NFC tag (211a) may include location information of the first wireless charging table (211), communication setting information required for communication connection with the first wireless power transmitting device (100), and connection information of a server (300) to be connected for purposes such as charging according to wireless charging. For convenience of explanation, an NFC tag is described as an example, but the same function can be performed using an RFID tag, a QR code, and an MST device.

The first NFC tag (211a) may include location information of the first wireless charging table, for example, coordinates (x1, y1, z1), or wireless charging table ID, communication setting information necessary for establishing communication with the first wireless power transmission device (100), such as an IP address and MAC address, and the IP address of the server (300).

The second wireless power transmitter (103) corresponds to the second wireless charging table (213). A second NFC tag (213a) may be attached to the second wireless charging table (213), and the second NFC tag (213a) may include location information of the second wireless charging table (213), communication setting information required for communication connection with the second wireless power transmitter (103), and connection information of a server (300) to be connected for purposes such as billing. For example, the second NFC tag (213a) may include coordinates (x2, y2, z2) of the second wireless charging table or a wireless charging table ID, communication setting information required for communication setup with the second wireless power transmitter (103), such as a MAC address of the wireless power transmitter (103), and an IP address of the server (300).

The third wireless power transmitter (105) corresponds to the third wireless charging table (215). A third NFC tag (215a) may be attached to the third wireless charging table (215), and the third NFC tag (215a) may include location information of the third wireless charging table (215), communication setting information required for communication connection with the third wireless power transmitter (100), and connection information of a server (300) to be connected for purposes such as billing. For example, the third NFC tag (215a) may include communication setting information required for communication setup with the third wireless power transmitter (105), such as coordinates (x3, y3, z3) of the wireless charging table or a wireless charging table ID, a MAC address of the third wireless power transmitter (105), and an IP address of the server (300).

In this example, one wireless charging table corresponds to one wireless power transmitter, but this is not limited to the example, and one wireless power transmitter corresponds to multiple wireless charging tables, and it is also possible to wirelessly provide power to wireless power receivers placed on each of the multiple tables for charging.

The functions and components of the wireless power transmitter (100, 103, 105) and the wireless power receiver (200) are the same as those described with reference to FIG. 4, so detailed descriptions are omitted here.

The server (300) can communicate with the wireless power transmitter (100, 103, 105) and the wireless power receiver (200). The server (300) can manage the wireless charging function of the wireless power transmitter (100, 103, 105) by performing the communication. For example, when the position of the wireless power receiver (200) changes, the server (300) can determine the wireless power transmitter based on the changed position information and cause the corresponding wireless power transmitter to transmit wireless power to the wireless power receiver (200). For example, when a user brings the wireless power receiver (200) close to or into contact with the first NFC tag (211a) on the first wireless charging table (211) to receive wireless power, the wireless power receiver (200) can transmit position information included in the first NFC tag (211a) to the server (300). The server (300) can check the location information related to the received wireless charging area, determine the wireless charging transmission device corresponding to the checked location information as the first wireless power transmission device (100), and request the first wireless power transmission device (100) to transmit wireless power to the wireless power reception device (200).

According to an embodiment, the wireless power receiver (200) can transmit payment information to the server (300), and the server (300) can analyze the payment information to determine the amount of power to be transmitted to the wireless power receiver (200) and control the wireless power transmitter (100) to transmit wireless power in the amount of power determined accordingly. While receiving wireless power from the first wireless power transmitter (100), when the user moves the wireless power receiver (200) to the third wireless charging table (215) and brings the wireless power receiver (200) close to or into contact with the third NFC tag (215a), the wireless power receiver (200) transmits location information related to the wireless charging area related to the third wireless charging table received from the third NFC tag (215a), device information of the wireless power receiver (200), and communication setting information of the wireless power receiver (200) to the server (300).

The server (300) may request the third wireless power transmitter (105) to transmit wireless power to the wireless power receiver (200) based on the location information (x3, y3, z3) related to the received wireless charging area and the device information of the wireless power receiver (200). Meanwhile, the first wireless power transmitter (100) may transmit wireless power to the wireless power receiver (200) while continuously communicating with the wireless power receiver (200), and may stop wireless power transmission when it is determined that the wireless power receiver (200) is no longer receiving power.

In addition, the server (300) may receive information about the amount of wireless power transmitted from the first wireless power transmitter (100) to the wireless power receiver (200), and may determine the amount of wireless power to be transmitted by the third wireless power transmitter (105) to the wireless power receiver (200) based on the information. For example, if the amount of power to be supplied to the wireless power receiver (200) is 3 KW and the amount of power supplied from the first wireless power transmitter (100) to the wireless power receiver (200) is 2 KW, the server (300) may determine the amount of power to be transmitted by the third wireless power transmitter (105) to the wireless power receiver (200) as 1 KW. The information about the determined amount of power may be transmitted to the third wireless power transmitter (105), so that the wireless power transmitter (105) may transmit power equivalent to the corresponding amount of power to the wireless power receiver (200).

FIG. 6 illustrates an example of a wireless charging system using a magnetic induction type wireless power transmission device according to an embodiment of the present disclosure.

Referring to FIG. 6, a wireless power transmitter (100), a wireless power receiver (200), and a server (300) are illustrated.

The wireless power transmitter (100) may be provided in the form of, for example, a charging pad, and when the wireless power receiver (200) is placed on the charging pad, the wireless power receiver (200) may receive wireless power (400) and be charged. The distance between the wireless power transmitter (100) and the wireless power receiver (200) may preferably be 1 cm or less.

The wireless power receiver (200) can receive wireless power (400) from the wireless power transmitter (100) and provide power to a load (e.g., a battery) electrically connected to the wireless power receiver (200) to perform charging. In addition, the wireless power receiver (200) can transmit a signal requesting wireless power transmission, information required for wireless power reception, status information, wireless power transmitter (100) control information, payment information, etc. to the wireless power transmitter (100).

The wireless power receiver (200) can transmit the above information to the wireless power transmitter (100) through an in-band communication method. For example, the wireless power receiver (200) can transmit payment information of the wireless power receiver (200), a signal requesting wireless power transmission, information required for wireless power reception, status information, and wireless power transmitter (100) control information to the wireless power transmitter (100) by using a change in the magnetic field of a coil that receives wireless power. Accordingly, a user can charge the wireless power receiver (200) simply by placing the wireless power receiver (200) on a charging pad without a separate payment process. In addition, since an authentication process is performed between the wireless power transmitter (100) and the wireless power receiver (200) by transmitting the payment information to the wireless power transmitter (100), a separate authentication process step can be omitted. Additionally, by using an in-band communication method, the pairing process for establishing communication between the wireless power transmitter (100) and the wireless power receiver (200) can be omitted.

For example, when a user runs a credit card app on a wireless power receiver (200) and then places the wireless power receiver (200) on a charging pad, payment information (e.g., credit card number) required for payment can be transmitted to the wireless power transmitter (100) through the wireless charging coil, and the wireless power transmitter (100) can transmit the received payment information to a server (300) to proceed with payment.

According to an embodiment, the wireless power receiver (200) can transmit payment information to the server (300) through an out-of-band communication method. The server (300) can determine the amount of wireless power to be transmitted by the wireless power transmitter (100) to the wireless power receiver (200) based on the received payment information, and transmit the determined amount of power to the wireless power transmitter (100).

According to an embodiment, a credit card payment terminal (not shown) may be placed around a wireless power transmitter (100). When a user places a wireless power receiver (200) on a charging pad including a wireless power transmitter (100), a coil built into the wireless power receiver (200) generates a magnetic field corresponding to information required for payment (e.g., a credit card number) according to an MST (magnetic secure transmission) communication method, and the credit card payment terminal may receive the magnetic field and proceed with payment.

FIG. 7 illustrates an example of a wireless charging system using a magnetic resonance wireless power transmission device according to an embodiment of the present disclosure.

Referring to FIG. 7, a wireless power transmitter (100), a wireless power receiver (200), and a server (300) are illustrated.

The wireless power receiver (200) can receive wireless power (400) from the wireless power transmitter (100) and provide power to a load (e.g., a battery) electrically connected to the wireless power receiver (200) to charge the battery.

The wireless power receiver (200) can transmit information necessary for receiving wireless power from the wireless power transmitter (100), such as payment information, a signal requesting wireless power transmission, and status information of the wireless power receiver (200), to the wireless power transmitter (100) through an out-band communication method (401) via a communication unit. For example, the wireless power receiver (200) can transmit payment information, a wireless power transmission request signal, or status information of the wireless power receiver (200) to the wireless power transmitter (100) using short-range communication such as Bluetooth or WiFi.

The wireless power transmitter (100) can authenticate the wireless power receiver (200) using payment information received from the wireless power receiver (200) and transmit wireless power to the wireless power receiver (200). In addition, the wireless power transmitter (100) can transmit the received payment information to the server (300). The server (300) can perform payment for an amount corresponding to the amount of wireless power transmitted to the wireless power receiver (100) based on the received payment information of the wireless power receiver (200). In addition, the wireless power transmitter (100) can receive status information of the wireless power receiver (200) from the wireless power receiver (200) and stop wireless power transmission based on the status information. For example, when the wireless power transmitter (100) receives a charging completion signal from the wireless power receiver (200), the wireless power transmitter (100) may stop wireless power transmission based on the charging completion signal, and may transmit information on the amount of wireless power received from the wireless power transmitter (100) transmitted by the wireless power receiver (200) or information on the amount of wireless power transmitted by the wireless power transmitter (100) to the wireless power receiver (200) to the server (300). The server (300) may determine a usage fee based on the information on the amount of wireless power received, and may perform payment for the determined usage fee using payment information.

According to an embodiment, a card payment terminal (not shown) may be placed around a wireless power transmitter (100). When a user places a wireless power receiver (200) on a charging pad including a wireless power transmitter (100), a coil built into the wireless power receiver (200) generates a magnetic field corresponding to payment information (e.g., card number) required for payment according to the MST method, and the card payment terminal may receive the magnetic field to obtain payment information and transmit the obtained payment information to a server (300). The server (300) may perform payment using the card number.

FIG. 8 is a flowchart illustrating a process in which a wireless power transmission device according to an embodiment of the present disclosure transmits wireless power to a wireless power reception device.

Referring to FIG. 8, a wireless power transmitter receives device information of a wireless power receiver from a server (S801). The wireless power transmitter can transmit wireless power to a wireless power receiver using at least one of an induction method, a resonance method, and an electromagnetic wave method. The server can receive device information of the wireless power receiver from the wireless power receiver. The device information may be ID information or a MAC address that can identify the wireless power receiver on a network. In addition, the server can receive payment information from the wireless power receiver. The payment information is information required for the wireless power receiver to charge for receiving wireless power, and may be, for example, credit card information of a user using the wireless power receiver.

The wireless power transmitter authenticates the wireless power receiver based on device information (S803). The wireless power transmitter receives device information from wireless power receivers located nearby. For convenience of explanation, the device information received by the wireless power transmitter from the server is referred to as first device information, and the device information received directly from the wireless power receiver is referred to as second device information. The wireless power transmitter compares the first device and second device information, and if they are identical, the wireless power receiver that transmitted the second device information can be authenticated as the wireless power receiver to which the wireless power transmitter should provide wireless power.

A wireless power transmitter may use an in-band communication method to receive device information from a wireless power receiver. For example, in the case of an inductive wireless power transmitter, the second device information may be received from the wireless power receiver using a change in the magnetic field of an induction coil that transmits wireless power. In the case of a wireless power transmitter using a resonance method or an electromagnetic wave method, the second device information may be received from the wireless power receiver using out-of-band communication. In the case of a wireless power transmitter using a resonance method or an electromagnetic wave method, the second device information may be received from the wireless power receiver using short-range communication such as Bluetooth or Wi-Fi, for example.

The wireless power transmitter transmits wireless power to the wireless power receiver based on the authentication result (S805). If the first device information and the second device information match, the wireless power transmitter determines that authentication is successful and can transmit wireless power to the wireless power receiver. Additionally, the wireless power transmitter can determine a method for transmitting wireless power to the wireless power receiver before transmitting wireless power to the wireless power receiver. For example, the wireless power receiver can receive information about a wireless power transmission method supported by the wireless power receiver through in-band communication or out-of-band communication with the wireless power receiver to determine the power transmission method. The wireless power transmitter can wirelessly transmit power to the wireless power receiver using components included in the wireless power transmitter according to the determined power transmission method. For example, if the determined wireless power transmission method is a magnetic induction method, an induction coil can be used to transmit wireless power to the wireless power receiver, if a magnetic resonance method is used, a resonator can be used, and if an electromagnetic wave method is used, an array antenna can be used.

FIG. 9 is a flowchart illustrating a process of adjusting the amount of wireless power transmitted to a wireless power receiving device by a wireless power transmission device using payment information according to another embodiment of the present disclosure.

Referring to FIG. 9, the wireless power transmitter receives information on the wireless power amount determined based on payment information of the wireless power receiver from the server (S901). The server can use the payment information received from the card payment terminal or the wireless power receiver to determine the amount of wireless power to be transmitted by the wireless power transmitter to the wireless power receiver. For example, when a user of the wireless power receiver pays a certain amount, the server verifies the amount of wireless power corresponding to the payment amount. The server transmits information on the verified amount of wireless power to the wireless power transmitter.

The wireless power transmitter adjusts the amount of wireless power transmitted to the wireless power receiver based on information about the amount of power received from the server (S903). When the wireless power transmitter receives information about the amount of wireless power, it transmits power to the wireless power receiver based on the information about the amount of power. The wireless power transmitter continuously monitors the amount of wireless power transmitted, and can adjust the amount of wireless power transmitted to the wireless power receiver by stopping the transmission when a predetermined value is reached. For example, if the amount of wireless power corresponding to the amount paid by the user is 3KW, the wireless power transmitter monitors the amount of power transmitted to the wireless power receiver, and stops the wireless power transmission to the wireless power receiver when it reaches 3KW.

According to the embodiment, after receiving charging completion data from the wireless power receiver, the wireless power transmitter transmits information about the amount of wireless power transmitted to the wireless power receiver to the server, and the server can charge for the amount of wireless power. This process is described using FIG. 10.

FIG. 10 is a flowchart illustrating a process of transmitting information on the amount of wireless power transmitted by a wireless power transmission device to a wireless power reception device to a server according to another embodiment of the present disclosure.

Referring to FIG. 10, the wireless power transmitter receives a charging completion signal from the wireless power receiver (S1001). The wireless power transmitter can receive the charging completion signal from the wireless power receiver via in-band or out-of-band communication. Descriptions of in-band and out-of-band communication are omitted here as they have been described in detail in the description section of FIG. 9.

The charging completion signal can be transmitted from the wireless power receiver to the wireless power transmitter when the battery contained in the wireless power receiver is fully charged or charged to a user-set value. Furthermore, the charging completion signal can also be transmitted to the wireless power transmitter when the wireless power receiver finishes receiving wireless power while transmitting wireless power to the wireless power transmitter.

Additionally, even when charging is interrupted by the user, a charging completion signal may be transmitted to the wireless power transmitter. The wireless power transmitter interrupts wireless power transmission based on the charging completion signal (S1003). Optionally, when the wireless power transmitter receives a charging completion signal from the wireless power receiver, the wireless power transmitter may transmit the wireless power at a lower intensity than before the charging completion signal was received.

The wireless power transmitter determines the amount of wireless power transmitted to the wireless power receiver based on the charging completion signal (S1005). The wireless power transmitter determines the amount of wireless power transmitted to the wireless power receiver from the time wireless power transmission begins until the time the charging completion signal is received.

The wireless power transmitter transmits information about the amount of power transmitted to the wireless power receiver to the server (S1007). Once the amount of power transmitted to the wireless power receiver is determined, the wireless power transmitter transmits this information to the server, allowing the server to calculate the fee using the received information about the amount of power.

FIG. 11 illustrates a process in which a wireless power transmission device transmits wireless power to a wireless power reception device according to another embodiment of the present disclosure.

Referring to FIG. 11, the wireless power transmitter receives device information of the wireless power receiver and location information of a first point where the wireless power receiver is located from the wireless power receiver (S1101). The wireless power transmitter of the present embodiment can transmit wireless power using electromagnetic waves.
