The present embodiments can be applied to all machines, terminals, and smart devices requiring electric charging such as a smart phone, a tablet PC, a notebook, an electric bicycle, an electric kickboard, and an electric bike. Hereinafter, .

In this specification, the electric energy amount measurement technology based on the intelligent watt hour meter for supplying electric power or charging electricity may be implemented in the form of a platform service for an individual user, or may be implemented by a power exchange (hereinafter referred to as & May be implemented in the form of a platform service. In addition, it may be implemented in the form of a platform service for a power supplier (for example, KEPCO) that supplies power.

And, in this specification, an electric power metering technique based on an intelligent watt-hour meter may be used for managing supply and charging of renewable energy generating electricity in addition to electric power supply and electric charging.

In this specification, a power supply (e.g., a power supply) is provided to receive power from a power user who provides power to an individual user or an individual user who possesses a user terminal that requires power supply It is assumed that a power supply such as an electric charge is provided in the state that a separate contract with the Korea Electric Power Corporation is concluded. For example, the electric power metering system or the electric power consumer can conclude consignment sales contracts for electric power sales from KEPCO.

1 is a view for explaining an overall operation of a watt-hour meter system using an intelligent watt-hour meter according to an embodiment of the present invention. In Fig. 1, an outlet may include both a sloped socket-outlet and a detachable socket-outlet.

The user terminal 110 may be a smart phone, a tablet, a wearable computer, an electric bike, a motorized kickboard, or the like, and may refer to all terminal devices that require power supply and electric charging . Authenticates an outlet or plug 120 used to supply power to the user terminal 110 and provides power to the user terminal 110 through an outlet or plug 120 to meter the amount of power supplied, An application for processing a process such as settlement can be installed. As such, the energy metering system can be implemented as a platform service for individual users. When the application is executed, the application establishes a communication session with the wireless communication module provided in the receptacle or the plug 120 through the wireless communication module provided in the user terminal 110, It can be authenticated whether or not it is assigned to the terminal 110. here. The wireless communication module may include communication modules such as NFC, Beacon, WiFi, Zigbee, and Bluetooth.

If the outlet or plug 120 is authenticated as a user terminal 110, power may be supplied from the power supplier 130 to the user terminal 110. That is, the authentication for the outlet (including the detachable type) or the plug 120 can be performed in batch before power supply.

At this time, authentication of the user terminal 110 is also performed before the power is supplied, and power can be supplied from the power supplier 130 to the user terminal 110 after the user terminal 110 is authenticated. The amount of power supplied from the power supplier 130 to the user terminal 110 may be measured by the intelligent watt-hour meter 140. The intelligent watt hour meter 140 integrates a number of technologies and applications such as intelligent WHAT (Watt Hour Meters), a wide area communication infrastructure, a home network (Home Area Network), a meter data management system (MDMS) Lt; / RTI > Intelligent WHM is a programmable instrument that can provide a variety of additional services including power quality information, time-of-day rates, power consumption analysis, and bi-directional metering.

On the other hand, as the outlet / plug 120 is authenticated and the user terminal 110 is authenticated, power is supplied to the user terminal 110, and as it measures the amount of power provided to the user terminal 110 in the intelligent watt- An electricity bill may be charged to the user 101 by separating the electricity bill from the business owner of the place where the electric power 110 is supplied with electric power (for example, a business place such as a coffee shop). If the user terminal 110 receives authentication in advance and receives power from the user terminal 110 in advance, the electricity rate for the supplied electric power is not provided to the user terminal 110, , An intelligent watt-hour meter, or the like.

The electricity bill and the electric power amount calculated based on the electric power amount measured in the intelligent watt hour meter 140 can be displayed on at least one of the plug, the outlet, and the user terminal 110. [ For example, the amount of electricity used and the charge used through the display attached to the plug / receptacle 120 may be displayed, and the amount of the electric power and the charge may be displayed on the display of the user terminal including the wearable device.

 In addition, electric charges corresponding to the amount of electric power supplied through the outlet / plug 120 having the technologies such as IoT (Internet of Things) and O2O (Online to Offline) are imposed, and thereafter, the electricity amount measured by the intelligent watt- And the electricity amount may be recalculated through authentication to compare the supplied amount of electricity. For example, an IoT communication module may be attached to the receptacle / plug 120, The user terminal 110 can be authenticated by communicating with the user terminal 110 through the IoT communication module. Then, when the user terminal 110 is authenticated, an electricity bill may be charged based on the location of the outlet / plug 120, the location of the user terminal 110, and the amount of electric power corresponding to the charge added from the meter of the KEPCO subscriber Can be excluded.

In addition, an energy storage device (ESS) may be further utilized to increase the efficiency of power usage.

Hereinafter, a configuration for authenticating the outlet, the plug, and the user terminal described above, the configuration for measuring and charging the amount of power, and the configuration for using the energy storage device will be described in detail with reference to the drawings.

Figure 2 shows a power metering system and a user terminal in one embodiment of the present invention. In particular, FIG. 2 is intended to illustrate a configuration for identifying the location information given to the outlet and providing a power supply or an electric charge to the user terminal. 2, the arrow indicates that data can be transmitted and received between the user terminal 301 and the power metering system 300, the power metering system 300, and the power provider 204 using a wired or wireless network.

The power metering system 300 includes a plug, a charger, and an electrical outlet (not shown) electrically connected to the user terminal 300 to provide power and charge electrical power to the user terminal 300, It is possible to identify position information assigned to at least one electronic device. For example, location information may be identified using power line communication (PLC) or Internet communications and, if location information is identified, the power metering system 300 may provide power to the user terminal 301, The plug 302, or the user terminal 301 to be provided. Then, the electric power metering system 300 can calculate and charge the electric charges resulting from power supply and charging.

In addition, the power metering system 300 can operate as a server of the power seller or the power supplier 204, but also acts as a mediator between the operator and the power supplier as a power seller, You may. For example, the service provider can perform an intermediary role between the service provider and KEPCO so as to provide power supply and charge to the user who visited the service provider.

At this time, when the electric power metering system 300 is in the state of accepting electric power or mediating between the electric power supplier and the electric power supplier, it is possible to charge an electric charge to the user or electric power user of the user terminal which is supplied with power or performs electric charging, The electric power supplier (for example, KEPCO) may pay a fee for the electric power used in accordance with the conditions of the contract separately from the electric power supplier.

FIG. 3 is a block diagram illustrating an internal configuration of a power metering system according to an exemplary embodiment of the present invention. FIG. 4 is a flowchart illustrating a method of identifying a power and a charge according to an embodiment of the present invention. Fig.

Referring to FIG. 3, the power metering system 300 may include a location information identification unit 310 and a calculation unit 320. The location information identification unit 310 and the calculation unit 320 may be configured to perform the steps 410 to 430 of FIG. 4 and the steps 610 to 630 of FIG.

If the electric power contracting system is approved by the electric power supplier KEPCO, the electric power metering system 300 places the outlet provided with the location information in the facility (for example, building) for power supply and charging can do. Here, the location information is an identifier (ID) assigned to identify the outlet, and a different ID may be assigned to each facility or power consumer, and the location information may be assigned to each facility Other IDs may be assigned.

For example, when charging is provided to a user terminal directly at a power metering system 300, that is, to an individual user, a plurality of outlets assigned to facilities (locations such as a building providing charging) IDs may be assigned to each facility, and different IDs may be assigned to a plurality of outlets assigned to one facility. In a power metering system 300, when powering and charging power to one or more power consumers, for example, ID1 is allotted to 10 outlets assigned to power cus- tomer 1 (e.g., coffee shop operator) ID2 can be allotted to 10 outlets assigned to 2 (for example, a large-scale mart business). In addition, ID1 to ID10 may be assigned to 10 outlets assigned to power consumer 1, respectively, and ID11 to ID20 may be assigned to 10 outlets assigned to power consumer 2, respectively.

Then, the electric power metering system 300 calculates the identification information (e.g., business name / building name, work permit number, workplace / facility phone number, workplace / facility address, etc.) And can be stored and managed in a database (not shown).

At this time, if the user terminal 303 needs to be charged or requires power supply, the user terminal 303 can be connected to the outlet with the wired / wireless charger or the plug electrically connected to the power supply and charging. For example, the user terminal 303, the plug 302, and the receptacle 301 can be electrically connected by inserting a wired charger or plug detached to the user terminal into the outlet. In addition, the wireless charger, the user terminal 303 and the outlet 301 can be connected to each other by placing the user terminal on a wireless charger (not shown) or placing the user terminal in the vicinity of the wireless charger, Can be electrically connected.

First, in step 410, as the user terminal 303 is connected to the outlet 301 through an electronic device such as a charger or a plug, the location information identification unit 310 identifies location information assigned to the outlet 302 . For example, the location information identification unit 310 can identify location information assigned to the outlet 302 electrically connected to the user terminal 303 using Internet communication or power line communication (PLC). In addition, a wireless communication chip including positional information may be embedded in the receptacle 301, and as the user terminal 303 and the receptacle 301 are electrically connected, the positional information identification unit 310 may be connected to the wireless communication chip The location information of the outlet can be identified.

In operation 420, the location information identification unit 310 can confirm the power subscriber information corresponding to the location information in a database (not shown).

For example, the location information identification unit 310 can check whether there is power subscriber information matching the identification information (ID) of the outlet in the database. When the power subscriber information is present, the location information identification unit 310 identifies the location where the outlet 301 is installed or the location where the outlet 301 is allocated (for example, the location of the outlet where the outlet is installed, . That is, as there is power subscriber information in the database, the subscribed power consumer for powering and charging can be authenticated.

In step 430, as the power subscriber information is verified and the authentication succeeds, the user terminal 303 may be provided with a power supply or an electric charge, and the calculation unit 320 may calculate the power supply of the user terminal 303, It is possible to calculate the fee according to

For example, if the power subscriber information is verified to successfully authenticate the power consumer or facility, power is supplied to the user terminal 303 through the plug 301 and the plug 302, .

When the electric power supply or electric charge is completed or stopped, the calculation unit 320 can calculate the charge rate based on the electric power supply or the electric charge.

For example, if the user terminal 303 removes the plug 302 from the receptacle 301 and the electrical connection between the user terminal 303 and the receptacle 301 is released so that the electrical supply or charging can be completed or stopped, The electric supply or the charging may be completed or stopped when the electric charge is full even if it is not physically detached from the receptacle 301 or when the specified charging time has elapsed. The calculation unit 320 can then calculate the charge for electric charging or electricity supply based on the amount of electric power per hour based on the time that the user terminal 303 has plugged in the plug 301 from the outlet 301 and then removed.

For example, the calculation unit 320 may calculate a charge based on power supply or charge based on the number of charge, the charge time, the charge amount or the number of times of power supply, the supply time, and the power supply amount, ), Or it may be imposed on a power consumer. When charged to a power consumer, the calculator 320 can charge the power consumers for monthly charges and charges for multiple users who have performed powering or charging through the power consumer, The fare can be settled. At this time, the calculation unit 320 can charge the fee in various ways, and detailed operation for charging the fee will be described later with reference to FIG.

At this time, there may be an error between the actual amount of power supplied by the power supplier (e.g., KEPCO) 140 and the amount of power measured by the intelligent watt-hour meter 140. [ Accordingly, charges are imposed depending on the usage amount through the plug or the receptacle, but can be excluded from the meter of the user on the basis of the following equations (1) and (2) when imposed.

In Equation (1), the input value Pi is an input value of the watt-hour meter 140 and is an ideal value, and may correspond to a usage amount in a plug or an outlet. For example, in Equation (2), the calculation unit 320 may calculate the input value Pi based on a least squares method. The error E can be calculated based on the input value of the watt-hour meter 140 and the output value of the watt-hour meter 140. The output value Po is a measured power amount measured by the intelligent watt- Then, the calculator 320 can calculate the charge for the electric power supply or the electric charge by excluding the electric power corresponding to the error E from the meter of the user corresponding to the outlet or the plug which is authenticated. As such, the amount of electric power can be measured for each receptacle or plug through the intelligent watt-hour meter 140, and the fee calculated according to the measured amount of electric power can be displayed on the display provided on the user terminal or the outlet or the plug. The detailed operation of billing and settlement of the charges calculated by the calculation unit 320 will be described later with reference to FIG.

FIG. 5 shows a power metering system and a user terminal in another embodiment of the present invention, and FIG. 6 is a flowchart showing a method of measuring the amount of power by identifying the position information of the plug. In particular, Figs. 5 and 6 are for explaining a configuration for identifying the position information given to the plug and providing a power supply or electric charge to the user terminal.

5, the arrow indicates that data can be transmitted and received between the user terminal 501 and the power metering system 500, the power metering system 500, and the power provider 504 using a wired or wireless network. 5, operations of the user terminal 501 and the power supplier 504 are the same as those in FIG. 1, so that a duplicate description will be omitted.

5 is a system in which position information (e.g., ID) is given to the plug 502 unlike FIG. 2, and is provided for managing power supply and charge using an existing outlet that is not assigned an ID. The ID-assigned plug 502 may be distributed to individual users subscribed to the power metering system 500 for powering and charging, or may be provided to an outlet (not shown) If it is difficult to install, it may be distributed to power consumers. Then, the database (not shown) of the power metering system 500 can match and store and manage the power subscriber information registered by the individual user and the power consumer at the time of subscription and the location information (e.g., ID) assigned to the plug.

When the user terminal 501 requires electric power supply or electric charging, it can supply electric power by using its own plug 502 in places such as a coffee shop, a large-sized mart, an amusement park, a department store, Electric charge can be provided. For example, when the user terminal 501 intends to charge the facility in an installation where no outlet is provided with an ID, a plug 502 to which an ID is assigned is inserted into the outlet installed in the facility, The terminal 502 and the user terminal 501 may be electrically connected.

In this way, in the case of electrically connected, in operation 610, the location information identification unit 310 can identify the ID allocated to the plug 502 using the power line communication or the Internet communication. At this time, the wireless communication chip to which the ID of the plug is allocated may be embedded in the plug 502, and the position information identification unit 310 may identify the ID of the plug through the wireless communication chip built in the plug 502 .

In step 620, the location information identification unit 310 determines whether the power subscriber information matching the ID of the identified plug exists in the database, and then authenticates the user or the power user assigned the plug 502 . By authenticating the user or power consumer using the ID of the plug, the user terminal 501 can be provided with an electrical charge.

In step 630, the calculation unit 320 may calculate and charge a charge based on the electricity supply / charge of the user terminal 501. For example, when the power supply or the electric charging of the user terminal 501 is completed or stopped, the calculation unit 320 may calculate the charging charge based on the electric power supply or the electric charging. At this time, the calculation unit 320 can calculate the charge rate based on the number of times of charge, the charge time, or the charge amount, and charge the calculated charge rate to the person who has been allocated the plug 502. [

For example, when a plug with an ID is assigned to a registered user, the calculation unit 320 can charge a charging fee to a user who has been assigned a plug regardless of the place where the outlet is installed. That is, in the case of charging the user terminal 501 at a coffee shop, a department store, etc., the charging fee may be imposed on the user of the user terminal 501, rather than being charged to a coffee shop, a department store or the like.

As another example, if a plug with an ID assigned to a power consumer is assigned, the calculation unit 320 can charge the power consumer who is the business owner of the business where the outlet is installed. The electric power consumer may include an intermediary who separately contracts with an electric power supplier (for example, KEPCO) and sells electric power to the business site, in addition to the business owner of the business site. Then, the power consumer can receive a predetermined charging fee from the user of the user terminal 501 that has performed the charging according to the number of charging, the charging amount, or the charging time. Then, the calculation unit 320 can pay the charging fee charged to the electric power supplier at a monthly or predetermined period, and can pay the electric power supplier.

At this time, when the charging fee is charged to the user and the electric power consumer, the calculation unit 320 may charge the fee for the power and charging service use in addition to the charging charge. In addition, the power metering system 500 may be configured such that the power consumer receives the revenues (e.g., commissions) paid by the user who has the user terminal 501 in exchange for providing charging to the user terminal 501 at a pre- Can be shared with power consumers. For example, the calculation unit 320 may charge the charging fee generated by charging the user using the plug 502 assigned with the ID assigned to the user, and separately from the business owner such as a coffee shop or the like ) Can charge the user a fee of 100 won for using the charging service. As such, if the revenues from the charge service use fee of 100 won occur, the power consumption system 500 can divide the revenues according to the predetermined ratio such as 5: 5, 3: 7, etc. with the coffee shop operator.

FIG. 7 is a flowchart provided to illustrate an operation of charging a fee according to an electric supply, in an embodiment of the present invention. FIG. In FIG. 7, electric charge is exemplified. However, charges may be charged depending on the amount of usage, as the power supply is interrupted while electric power is supplied to a notebook, a tablet or a smart phone in addition to electric charge. For example, the power supply may be interrupted as the user terminal is removed from the outlet, the plug by the user, or a power interruption or charge completion command is requested from the user terminal through the application. Then, a charge corresponding to the amount of power from the point of time when the electric power is supplied to the point of time when the electric power supply is stopped can be charged.

If the electrical charging of the user terminal is completed or stopped in step 710, the calculating unit 320 may calculate the charging charge based on the electric power supply or the electric charging in step 720. [

In step 730, the calculation unit 320 may charge the calculated charging fee to the user or the power consumer who owns the user terminal. At this time, the calculation unit 320 may charge a charging fee by various methods such as mobile payment, mobile phone payment, and land payment.

For example, when a user or a power consumer charges a charge to a user or a power consumer using a mobile payment service or a mobile payment service, the calculation unit 320 provides an interface for using the mobile payment service and the mobile payment service can do. For example, the calculation unit 320 may provide a settlement screen to a screen of a corresponding terminal through an interface formed with a terminal of a user terminal or a power user using Internet communication, power line communication, or the like.

Then, the calculation unit 320 calculates a settlement amount of the settlement means, such as a settlement means, a direct debit, a land settlement, a card settlement, a mobile phone settlement, etc., Can be selected. Here, the pre-registered payment means may include credit card information, check card information, account information, etc., registered in advance and authenticated by the user. For example, the user terminal 303 or the terminal of the power consumer may use the same or similar processes as a smart phone, a tablet PC, a notebook, a desktop, May be substantially the same. Hereinafter, a configuration for providing a settlement service to the user terminal 303 will be described as a representative example.

Then, the calculation unit 320 may perform the settlement procedure based on the payment means selected by the user.

For example, if previously registered credit card information is selected, the calculation unit 320 may perform a process of charging a charge fee to the user through the selected credit card in conjunction with the server of the selected credit card company. When previously registered account information is selected, the calculation unit 320 can perform the account transfer processing of the charge charge to the account pre-allocated to the power metering system through the selected account in cooperation with the bank server of the selected account.

At this time, if there is no pre-registered payment means, the calculation unit 320 may charge the charge charge through the payment means selected by the user. For example, the charging fee may be charged through card settlement or account transfer based on the credit card information, the check card information, or the account information input by the user, or when the user selects the payment by the user, (For example, a home / company address registered at the time of subscription or an address entered through the payment screen). In addition, when the mobile phone payment is selected, the calculation unit 320 transmits the authentication number to the user terminal 303, and then, through the terminal authentication for confirming the authentication number input through the user terminal 303, It can be processed to be charged together with the mobile phone charge. In addition to the above-described method, a charging fee may be charged to a payment method using various means such as points accumulated at the time of using the charging service or payment at an affiliate point.

FIG. 8 is a diagram for explaining a method of measuring the amount of power using an energy storage device according to an embodiment of the present invention. Referring to FIG.

Referring to FIG. 8, an energy storage system (ESS) 800 may be installed around the outlet 801 or the outlet 801. For example, the energy storage device 800 may be installed around the wall where the outlet 801 is installed.

The energy storage device 800 may store and store the power previously purchased from the power supplier, when the price of the power supplied by the power supplier is less than or equal to a preset reference price or the average price of the power price purchased for a month or a predetermined period. It can be kept. That is, when the power is low, the power may be purchased from the power supplier in advance and charged to the energy storage device 800 to provide charging to the user terminal that wants to charge the battery. As such, an electrical connection to the energy storage device 800 receptacle 801 may be established or terminated to provide charging to the user terminal. For example, when providing charging to a user terminal, the power metering system 200, 500 can control the energy storage device 800 and the receptacle 801 to be electrically connected, and need to provide charging to the user terminal It is possible to control so that the energy storage device 800 and the outlet 801 are not electrically connected.

As described above, the power metering system can supplement the energy storage device to manage the power supply and the charging, thereby providing charging service to the user terminal at a lower cost. In addition, since the power supply or charging service is provided to the user terminal through the authentication based on the electronic device such as the plug having the ID and the receptacle to which the ID is assigned, electricity can be supplied to the user without worrying about progressive tax due to power consumption , It is possible to provide a charging service to a user terminal at anytime and anywhere regardless of a place in a public place such as an airport or a train station and in various places,

The apparatus described above may be implemented as a hardware component, a software component, and / or a combination of hardware components and software components. For example, the apparatus and components described in the embodiments may be implemented within a computer system, such as, for example, a processor, a controller, an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a field programmable array (FPA) A programmable logic unit (PLU), a microprocessor, or any other device capable of executing and responding to instructions. The processing device may execute an operating system (OS) and one or more software applications running on the operating system. The processing device may also access, store, manipulate, process, and generate data in response to execution of the software.
