Hereinafter, an electric power demand apparatus charging system installed in a collective building according to the present invention will be described as an example of operating mainly for electric vehicle charging, but the present invention is not limited thereto. The charging system for electric power demand devices installed in the collective building according to the present invention can be applied not only to electric vehicles but also to all electric power demanding devices requiring a large amount of electric power to be charged and particularly to mobile electric power demanding devices. Further, the user authentication socket constituting the electric power demand device charging system installed in the assembly building according to the present invention may have a shape of a connector such as, for example, a cable embedded in a wall of a building or extending outward from a wall of the building .

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view illustrating a charging system for a power demanding apparatus installed in a collective building according to an embodiment of the present invention.

Referring to FIG. 1, the present invention includes a main power line connected to an external power source 10 and a power line connected to the power line via a common power line, The charging system includes an external power supply 10, a main power line ammeter 20, a dedicated power line ammeter 30, a common power line ammeter 40, an individual common power line ammeter 50, a breaker 60, a shutdown controller 70, A user authentication socket 100 and a charge mediation module 400.

The external power source 10 is the power supplied to the collective building where the power distribution is located in front of the customer in relation to the power supply. For example, a set building may be an apartment, an office building, an apartment factory, an officetel, a town house, a multi-family house, and the like. In terms of power usage, the collective building consists of a dedicated power load that can be used exclusively by the owner or resident and a common power load that can be used in common. The external power supply 10 supplies electric power to the assembly building via the main power line, and the main power line branches to a dedicated power line connected to the dedicated power load and a common power line connected to the common power load. The dedicated power lines are branched into individual dedicated power lines connected to respective dedicated power loads, and the common power lines branch to a plurality of individual common power lines connected to respective common power loads. For example, the common power load connected to a plurality of individual common power lines may be a variety of mobile power demand devices requiring charging, such as an electric vehicle 600, as well as electric lamps that are fixed facilities.

The main power line ammeter 20 is installed in the main power line, and measures the amount of power supplied through the main power line and transmits it to the cut-off controller 70.

The dedicated power line ammeter 30 is installed in the dedicated power line and performs a function of measuring the amount of power supplied through the dedicated power line and transmitting it to the block controller 70.

The common power line ammeter 40 is installed in a common power line, and measures the amount of power supplied through the common power line and transmits the measurement result to the cut-off controller 70.

The individual common power line ammeter 50 is installed in a plurality of individual common power lines branched from the common power line and performs a function of measuring the amount of power supplied through a plurality of individual common power lines and transmitting the measured amount of power to the blackout controller 70.

The circuit breaker 60 is installed in a plurality of individual common power lines and controls opening and closing under the control of the cut-off controller 70, thereby performing a function of determining whether power is supplied through the individual common power lines.

When the electric vehicle 600 is connected to a separate public power line and requests charging, the shutdown controller 70 disconnects the main power line ammeter 20, the dedicated power line ammeter 30, the common power line ammeter 40, the individual common power line ammeter 50 based on whether or not the calculated surplus current amount is equal to or greater than the set current threshold, the opening and closing of the circuit breaker 60 installed on the individual common power line to which the electric vehicle 600 is connected . For example, the shutdown controller 70 controls the current to flow through the circuit breaker 60 so that the circuit breaker 60 remains on when the surplus current amount is equal to or greater than the current threshold, If it is less than the threshold value, the circuit breaker 60 is turned off to control the current flow through the circuit breaker 60 to be blocked.

For example, when a plurality of electric vehicles 600 are connected to a plurality of individual common power lines to request charging, the block controller 70 generates a plurality of electric vehicles 600, And may be configured to give the electric vehicle 600 a charge priority. In this way, when the shutdown controller 70 is configured to give charge priorities to a plurality of electric vehicles 600, if there is a fear that an overload occurs in the collective building due to power shortage, It is possible to prevent the occurrence of the overload state of the collective building by allowing the charging electric power to be supplied only to a part of the electric vehicles 600 having the charge priority order.

For example, when the amount of surplus current becomes less than the current threshold during charging of the plurality of electric vehicles 600, the shutdown controller 70 controls the electric power of the plurality of electric vehicles 600 to the individual common power lines And may be configured to turn off the installed breaker 60 according to the reverse order of charge priority. With such a configuration, when there is a possibility that an overload will occur in an aggregate building due to an increase in power consumption in a dedicated electric power load or the like during charging, the charging state is not an overload state at the start of charging, It is possible to prevent the occurrence of the overload state of the collective building by sequentially shutting off the charging power supply from the electric vehicle 600 having the lowest charging priority among the electric vehicles 600. [ In this example, the shutdown controller 70 may be configured to turn on the circuit breakers 60 in the off state in the reverse order of the off sequence when the surplus current amount becomes the current threshold or more. With such a configuration, if the electric power situation is stably changed again after the charging is suspended due to the fluctuation of the electric power situation of the collective building during the charging of the electric vehicle 600, charging to the electric vehicle 600 is automatically It is possible to secure the convenience of charging the electric vehicle 600 and effectively prevent the occurrence of the overload state of the collective building.

The effect of this configuration will be described below in comparison with the prior art.

As described above, there is a problem in that the conventional charging facility can not adaptively cope with fluctuations in the power situation of the assembly building. For example, when the charging of the electric vehicle is forcibly terminated due to the fluctuation of electric power during the charging of the electric vehicle by using the charging facility provided in the underground parking lot of the collective building such as apartment, etc., the electric power situation is stable In order to resume charging even after returning, the user must go directly to the underground parking lot where the charging facility is installed and recognize that the charging subject is the charging facility. Therefore, there is a problem in that the user convenience is greatly reduced. However, according to the present invention, the shutdown controller 70 can be configured such that 1) when the surplus current amount becomes less than the current threshold during charging of the plurality of electric vehicles 600, that is, when there is a possibility of occurrence of overload, The circuit breaker 60 installed in the individual common power line to which the electric vehicle 600 of the electric vehicle 600 is connected is turned off according to the reverse order of the charge priorities, and 2) when the surplus current amount becomes the current threshold value or more, The on-state circuit breaker 60 is turned on in the reverse order of the off sequence, thereby greatly improving the convenience for the user in charging.

The user authentication socket 100 is connected to a separate common power line and is a means for connecting the electric vehicle 600 via the charge mediation module 400.

One end of the charging mediation module 400 is connected to the user authentication socket 100 and the other end is connected to the electric vehicle 600 to supply charging electric power to the electric vehicle 600, And transmits necessary information to the mediation server 500.

Hereinafter, a specific configuration for charging including the user authentication socket 100 and the charge mediation module 400 will be described.

FIG. 2 is a diagram illustrating an example of a specific configuration for charging including a user authentication socket 100 and a charge mediation module 400, according to an embodiment of the present invention.

First, after describing a characteristic configuration for charging, detailed components will be described.

Referring to FIG. 2, when the charge mediation module 400 is connected to the user authentication socket 100, the user authentication socket 100 transmits a minute current to the charge mediation module 400. The charging mediation module 400 requests outlet identification information to the user authentication receptacle 100 in response to the microcurrent and transmits the outlet ID information received from the user authentication receptacle 100 to the mediation server 500, And transmits the outlet operation password received from the mediation server 500 to the user authentication receptacle 100. [ When the outlet operation password transmitted from the charge mediation module 400 corresponds to the outlet ID information, the user authentication receptacle 100 receives the charging power supplied through the individual common power line through the charging mediation module 400, ).

More specifically, the microcurrent limiting device 150 generates a minute current when the charge mediation module 400 connected to the electric vehicle 600 is connected to the charge mediation module 400. The charging mediation module 400 and the electric vehicle 600 may be connected via a connector. For example, the microcurrent may be a low current of several tens of mA or less.

Next, the charge mediation module 400 converts the minute current into the power for authentication and transmits it to the first authentication terminal 120.

Next, the authentication device 110 provided in the user authentication receptacle 100 is operated by the authentication power transmitted from the charge mediation module 400 through the first authentication terminal 120, and transmits the outlet ID information to the charging intermediation Module 400 as shown in FIG.

Next, the charge mediation module 400 requests the outlet operation password corresponding to the outlet ID information while transmitting the outlet ID information to the mediation server 500, and transmits the outlet operation password transmitted from the mediation server 500 to the first authentication And transmits it to the authentication device 110 via the terminal 120.

Next, when the outlet operation password transmitted from the charge mediation module 400 corresponds to the outlet ID information, the authentication device 110 causes the charging power to be supplied to the electric vehicle 600 via the charge mediation module 400 .

For example, the power for authentication may be an outlet ID request signal requesting the ID of the user authentication receptacle 100. [

For example, when the electric vehicle 600 is disconnected from the user authentication receptacle 100, the microcurrent limiting device 150 may be configured to no longer generate a microcurrent.

For example, the first authentication terminal 120 of the user authentication receptacle 100 may be wirelessly connected to the charge mediation module 400 to receive the authentication power and the outlet operation password from the charge mediation module 400 wirelessly .

For example, the user authentication receptacle 100 may be configured to provide the allowable current amount information directly to the charge mediation module 400 through the outlet ID information.

For example, when the outlet operation password transmitted from the charge mediation module 400 corresponds to the outlet ID information, the authentication device 110 turns on the electromagnetic switch 130 so that the charging power supplied through the individual common power line is charged And can be controlled to be supplied to the electric vehicle 600 through the intermediary module 400.

The charging mediation module 400 receives the microcurrent generated when the electric vehicle 600 is connected to the user authentication socket 100 from the user authentication socket 100 and receives the socket operation password To the user authentication receptacle 100 and transmits the authentication power obtained from the microcurrent to the user authentication receptacle 100 and the charging power from the user authentication receptacle 100 to the electric vehicle 600 after the user authentication is completed To be supplied.

For example, the charge mediation module 400 may include an AC / DC converter 440 that converts minute current into direct current to generate power for authentication, and may be configured to not have its own built-in battery.

For example, the charge mediation module 400 may be configured to transmit energy amount information attributable to the electric vehicle 600 to the mediation server 500 per unit time period. The power amount information may be acquired by the power metering unit 430 provided in the charge mediation module 400. [

For example, when the electric vehicle 600 is disconnected from the user authentication receptacle 100, the electric energy amount information may be configured so that it is no longer transmitted to the intermediary server 500.

For example, the charge amount of the last unit time period before the communication between the charge mediation module 400 and the mediation server 500 may be regarded as the charge amount in the unit time period in which the communication interruption occurs.

For example, the charge mediation module 400 may be configured to transmit the allowable current amount information of the user authentication receptacle 100 corresponding to the outlet ID information of the user authentication receptacle 100 to the mediation server 500.

For example, the charge mediation module 400 may be configured to be integrated with a plug for connection to a user authenticated receptacle 100. In this case, the first power supply terminal 140 and the first authentication terminal 120 provided in the user authentication socket 100 are connected to the second power supply terminal 320 provided in the charge mediation module 400, And is connected to the second authentication terminal 310.

Hereinafter, an example of a detailed configuration of the user authentication socket 100 and the charge mediation module 400 will be described.

The user authentication socket 100 includes a microcurrent limiting device 150, a first power supply terminal 140, an authentication device 110, a first authentication terminal 120, an electromagnetic switch 130, . ≪ / RTI >

When the charge mediation module 400 is connected to the user authentication receptacle 100, the microcurrent limiting device 150 outputs a small current from the external power supply 10 through the microcurrent limiting device 150 to the first power supply terminal 140). In the state where the charging mediation module 400 is not connected to the user authentication socket 100, no minute current flows, so that standby power consumption in the user authentication socket 100 does not occur.

As one example, the microcurrent limiting device 150 can be implemented inexpensively and simply by connecting two resistors in parallel. The microcurrent thus flowed is transferred from the first power supply terminal 140 of the user authentication socket 100 to the second power supply terminal 320 of the charge mediation module 400.

As another example, the microcurrent limiting device 150 may be implemented as a resettable fuse. An example of a resettable fuse is a poly switch, an electronic device manufactured by Reychem of the United States. The polis position is very low resistance (0 ~ 5 ohms), and when the overcurrent flows into the circuit, it changes to high resistance by the joule heat due to the overcurrent. Thus, when the position of the polis is changed to a high resistance, the circuit is opened and the position of the polis plays the same role as the fuse. The difference from a normal fuse is that a resettable fuse can be re-used again when the cause of the overcurrent is removed and becomes low resistance. In the present invention, the polis position may be selected to have an allowable power that can limit the magnitude of the minute current to several tens of mA or less. For example, a police location with an allowable power of 20 W or less may be selected.

According to this configuration, the micro-current can be completely controlled. However, when the authentication power source is temporarily not supplied due to an external shock or the like during charging, the electromagnetic switch 130 is turned off, The electric power is in a state of inertia and a large electric power is to be supplied through the microcurrent limiting device 150. [

At this time, hundreds to several tens of times of the limit power of the microcurrent limiting device 150 is momentarily supplied and the microcurrent limiting device 150 blocks the same.

However, there is a fear that the microcurrent limiting device 150 is permanently burned out due to a power amount storm of several hundreds to several thousands times the allowable amount, so that the microcurrent limiting device 150 may not operate normally.

Therefore, the microcurrent limiting device 150 is additionally provided with a normal closed relay 170, and normally, when the control power is not supplied, the relay is kept in a close (on) state The microcurrent limiting device 150 can be prevented from being burned off by switching the control mode to the open state or the off state by supplying the control power to the normally closed relay 170 when the electromagnetic switch 130 is operated .

On the other hand, for example, a capacitor 160 may be added to the control power line between the authentication apparatus 110 and the normal closed relay 170 so that even after the control power supply is cut off, for example, . ≪ / RTI > With such a configuration, even when the authentication power source is temporarily not supplied due to an external impact or the like during charging, it is possible to prevent a sudden power storm from being applied to the microcurrent limiting device 150, thereby protecting the product.

On the other hand, when large electric power is supplied according to the charging of the electric vehicle 600, heat is generated in the supply terminal portion, which may cause a fire. In order to cope with this, the first power supply terminal 140 may additionally include a temperature sensor to measure the temperature of the heat generating portion to control the amount of charge (server control, authentication device control) or to stop charging.

The authentication device 110 receives the authentication power from the charge mediation module 400 and operates. The charging mediation module 400 receives the micro current from the user authentication socket 100 and converts the micro current into the power for authentication and then transmits the second authentication terminal 310 provided in the charging mediation module 400 To the first authentication terminal 120 provided in the user authentication receptacle 100 and the authentication device 110 transmits the authentication power from the charge mediation module 400 through the first authentication terminal 120 Receive. Specifically, the authentication device 110 is generated under the control of the control unit 410 provided in the charge mediation module 400 and is connected to the first authentication terminal 100 through the second authentication terminal 310, And transmits the socket ID information to the second authentication terminal (120) through the first authentication terminal (120) in response to the socket ID request signal, 310).

Here, the socket ID checking procedure may be performed by attaching an RFID tag or an NFC tag to the user authentication socket 100, installing an RFID rudder or an NFC reader in the charge mediation module 400, In a manner that directly reads out the outlet ID information from the outlet ID information. Further, the security can be further enhanced when the user authentication socket 100 transmits a fluid key value to the charge mediation module 400 together with the outlet ID information.

After the outlet ID checking procedure is performed, the authentication apparatus 110 receives the outlet operation password from the charge mediation module 400 through the first authentication terminal 120 and the second authentication terminal 310. [ The authentication device 110 closes the electromagnetic switch 130 to supply the charging power from the external power supply 10 if the outlet operation password transmitted from the charge mediation module 400 corresponds to the ID of the outlet operation. The charging power is transmitted to the second power supply terminal 320 of the charging mediation module 400 through the first power supply terminal 140 of the user authentication socket 100.

Once the electromagnetic switch 130 is closed, the DC power supplied from the second authentication terminal 310 or a part of the AC power supplied from the external power supply 10 is used to maintain the closing of the electromagnetic switch 130 . In this case, a portion of the AC power from the external power supply 10 is used to control the electromagnetic switch 130, in accordance with the specification of the electromagnetic switch 130, So that a separate AC / DC converter 440 for this can be dispensed with. In other words, the authentication device 110 is operated by the DC power, whereas the electromagnetic switch 130 receives the DC power from the outside and can be driven by the AC power after being triggered.

When closing the electromagnetic switch 130 by using the DC power supplied from the first authentication terminal 120, when the charge mediation module 400 is disconnected from the user authentication socket 100, DC power for controlling the electromagnetic switch 130 is not supplied from the terminal 310 for the electromagnetic switch 130 to open the electromagnetic switch 130. Alternatively, when closing the electromagnetic switch 130 by using a part of the AC power supplied from the external power supply 10, when the charging mediation module 400 is disconnected from the user authentication socket 100, The circuit to which the power supply 10 is supplied is opened and the AC power can no longer be supplied from the external power supply 10 so that the electromagnetic switch 130 is opened.

For example, the user authentication receptacle 100 may further include a changeover switch 180 for changing the user authentication socket 100 into an electric vehicle charging mode and a general electric device use mode. In order to prevent illegal use without proper authorization, for example, the changeover switch 180 may be configured to be protected by a lock device that is opened only by an administrator, or may be configured to be operable only with a key possessed by an administrator or the like have. When the administrator switches the changeover switch 180 to the general electric device use mode, the common electric device can be connected to receive the common power without a user authentication procedure. On the other hand, when the electromagnetic switch 130 is configured to be controlled to be turned on or off by alternating current, as shown in Figs. 4 and 5, even if a small-capacity current switch is applied to the switch 180, The same function can be implemented.

The charging mediation module 400 includes a second authentication terminal 310, a second power supply terminal 320, an AC / DC converter 440, a control unit 410, a wireless communication unit 420 and a power metering unit 430, . ≪ / RTI >

The AC / DC converter 440 converts the microcurrent of the alternating current supplied through the second power supply terminal 320 and the power metering unit 430 into a direct current to generate power for authentication.

The controller 410 controls the charging mediation module 400 as a whole, including power supply for authentication to the authentication device 110, transmission of the outlet ID request signal, reception of the outlet ID information, and reception of the outlet operation password from the mediation server 500 And controls the operation. Specifically, the control unit 410 supplies the authentication power generated by the AC / DC converter 440 to the authentication device 110 via the second authentication terminal 310 and the first authentication terminal 120 Respectively. Also, the controller 410 controls the socket ID request signal to be transmitted to the user authentication socket 100, and in response, controls the socket ID information transmitted by the user authentication socket 100 to be received.

Also, the control unit 410 controls the wireless communication unit 420 to acquire the outlet operation password through wireless communication with the mediation server 500. The thus obtained outlet operation password is provided to the authentication apparatus 110 via the second authentication terminal 310 and the first authentication terminal 120. [

Meanwhile, for example, the charge mediation module 400 may be configured to download the cipher to be used next at the end of the authentication sequence from the intermediary server 500, and deliver it to the authentication device 110 to store (110). With this configuration, it is possible to prevent the password leakage due to the use of the fixed password. That is, since the intermediary server 500 and the authentication apparatus 110 can compare the flow passwords, if the new password to be used next time is not input, charging can not be started, thereby enhancing the password leakage prevention function.

Alternatively, for example, the outlet activation password may be obtained from a database built into the charge mediation module 400 or the electric vehicle 600. However, if the number of the user authentication receptacle 100 increases, it may be difficult to store all the outlet operation passwords in the charge mediation module 400 or the electric vehicle 600. Accordingly, it is preferable to configure the charging mediation module 400 to acquire the outlet operation password from the mediation server 500 located outside via the wireless communication unit 420 in the process of acquiring the outlet operation password. Obtaining the outlet operation password from outside as described above can reduce the risk of leakage of the entire outlet operation password, which may occur when the mediation server 500 is not separately managed.

The power meter 430 meters the amount of power supplied from the user authentication socket 100 via the second power supply terminal 320. The metered power is supplied to the electric car 600). The measured amount of electric power information is transmitted to the control unit 410 and is transmitted to the mediation server 500 through the wireless communication via the wireless communication unit 420 based on the amount of the measured electric power under the control of the control unit 410 The amount of power to be charged in the vehicle 600 is transmitted.

The first authentication terminal 120 of the user authentication socket 100 may be connected to the second authentication terminal 310 of the charge mediation module 400 by wire or wirelessly. For example, in the case of a wireless connection, the first authentication terminal 120 wirelessly receives authentication power from the second authentication terminal 310 and wirelessly transmits / receives information to / from the second authentication terminal 310 And may be implemented in the form of a wireless power receiving and information transmitting and receiving unit. The second authentication terminal 310 wirelessly transmits power for authentication to the second authentication terminal 310 and wirelessly transmits and receives wireless power transmission information to and from the first authentication terminal 120. [ And an information transmission / reception unit.

6 is a diagram showing another example of a specific configuration for charging including the user authentication socket 100 and the charge mediation module 402 in one embodiment of the present invention.

2, the plug 300 including the second authentication terminal 310 and the second power supply terminal 320 may be provided separately from the charge mediation module 402 Can be implemented. In this case, for charging, the user can connect the plug 300 to the user authentication socket 100 after connecting the plug 300 to the charge mediation module 402.

7 is a view showing another example of a specific configuration for charging including the user authentication socket 100 and the charge mediation module 402 in one embodiment of the present invention.

Referring to FIG. 7, the charge mediating module 402 is integrated into a connector for connection to an electric vehicle 600, which is a power demanding device. According to this embodiment, since the filling mediation module 402 is embedded in the connector, the risk of damage, flooding, theft, etc. of the filling mediation module 402 can be reduced. For example, to prevent theft, mechanical / electronic locks may be built into the charge mediation module in the form of a connector.

Hereinafter, an example of a specific charging process will be described.

FIG. 8 is a view for explaining a process of starting charging of an electric vehicle 600 in an embodiment of the present invention, and FIG. 9 is a view for explaining a process of charging an electric vehicle 600 .

Referring to FIGS. 8 and 9, in step S100, a process of connecting the electric vehicle 600 to the user authentication socket 100 is performed through the charge mediation module 400. FIG.

In step S110, a process of energizing the microcurrent is performed.

In step S120, a minute current flows to the charge mediation module 400, and the charge mediation module 400 converts the minute current into the power for authentication and uses it.

In step S130, a process is performed in which the charge mediation module 400 acquires the outlet ID information transmitted by the user authentication receptacle 100. [

In step S140, the charging mediation module 400 transmits the outlet ID information to the mediation server 500 to request the outlet operation password.

In step S150, the process of transmitting the outlet operation password to the charge mediation module 400 is performed by the mediation server 500. [

In step S160, when the user authentication socket 100 receives the socket operation password from the charge mediation module 400 and the socket operation password corresponds to the socket ID information, the electronic switch 130 is closed, A process of supplying power to the first power supply terminal 140 through the switch 130 is performed.

In step S170, charging of the electric vehicle 600 is started as electric power supply is started.

In step S180, the charging mediation module 400 performs the process of transmitting the charging amount information provided to the electric vehicle 600 to the mediating server 500 every unit time period.

In step S190, a process of determining whether the charge mediation module 400 has completed charging of the electric vehicle 600 is performed. If it is determined that the charging is completed, the process proceeds to step S240. If it is determined that the charging is not completed, the process proceeds to step S200

In step S240, when the electric vehicle 600 is completely charged, the process of transmitting the final charge amount information to the mediation server 500 by the charge mediation module 400 is performed.

In step S200, a process of determining whether the connector is detached, that is, whether the charge mediation module 400 is disconnected from the electric vehicle 600, is performed. If it is determined in step S200 that the connector has been removed before charging is completed, the process proceeds to step S240. If it is determined that the connector is not detached, the process proceeds to step S210.

In step S210, the process of removing the charge mediation module 400, that is, the process of separating the charge mediation module 400 from the user authentication socket 100 is performed. This process may be performed by removing the plug connected to the charge mediation module 400 from the user authentication socket.

In step S220, since the microcurrent is no longer energized, the supply of the power for authentication is interrupted and the communication between the charge mediation module 400 and the mediation server 500 is interrupted.

In step S230, the charging amount in the last unit time period before communication between the charging mediation module 400 and the mediation server 500 is regarded as the charging amount in the unit time period in which the communication interruption occurs.

 In the charging process of the electric vehicle described above, the allowable current amount of the user authentication socket 100 may be different due to the limitation by the power transmission line and the like in some cases. In order to cope with this case, it is necessary to classify and provide the allowable current amount information of the user authentication socket 100. A concrete method of providing 1) a method in which the user authentication receptacle 100 provides the allowable current amount information directly to the charge mediation module 400 through the outlet ID information, 2) a method of providing the user authentication receptacle 100 In the mediation server 500 and the charging mediation module 400 receives the stored allowable current amount information from the mediation server 500 during the authentication process.

According to the present invention, since the authentication procedure is performed using the minute current that flows by the operation of connecting the charge mediation module 400 to the user authentication receptacle 100, the charge mediation module 400 does not have its own battery You do not have to.

Further, since the microcurrent limiting device 150 is used to limit the magnitude of the microcurrent, most of the electric devices including the mobile phone charger and the electric shaver are connected to the user authentication socket 100 without being subjected to the authentication procedure, .

Specifically, the maximum value of the microcurrent in the user authentication socket 100 may be, for example, 10 mA at the time of unauthentication (that is, before the authentication procedure is performed). Therefore, for example, when a heater with a rated power of 3,000 W is connected to the user authentication socket 100, only 2.2 W (220 V * 10 mA = 2.2 W) of power can be supplied, Electric heaters can not be used at all. As another example, in the case of a smartphone charger, a current of 0.15 A is required. Since the maximum value of the microcurrent provided by the user authentication socket 100 is only 10 mA, for example, Can not be used at all.

In other words, although the minute current amount (10 mA) has a sufficient size as an authentication power source for carrying out the authentication procedure, even an electric device having a small power consumption such as a smartphone charger can not be practically used. Even if electricity corresponding to the maximum value of the microcurrent is used all over the month, the electricity amount is only 220V * 0.01A * 24 hours * 31 days = 1.63kW, and it does not reach 200 won when converted into the amount.

According to the present invention, when a minute current flows only when the charging mediation module 400 is connected to the user authentication socket 100 and the charging mediation module 400 is disconnected from the user authentication socket 100, The charging agent module 400 is opened from the external power source 10 through the first power supply terminal 140 of the user authentication socket 100 and the second power supply terminal 320 of the charge mediation module 400, So that no current flows. The microcurrent does not flow when the charging mediation module 400 is not connected to the user authentication socket 100. Therefore, at the standby operation of the user authentication socket 100, the parts for user authentication consume power, i.e. standby power . This also eliminates the problem of inconsistencies between those who bear the cost of standby power (e.g., building owners, etc.) and real users (e.g., electric car owners, etc.).

Also, as described above, according to the present invention, the charge mediation module 400 may not have its own battery. In this case, when the charge mediation module 400 is disconnected from the user authentication socket 100, Module 400 may no longer be able to transmit power charge information to intermediary server 500, which may cause problems. 8 and 9, the wireless communication unit 420 of the charge mediation module 400 may be configured to periodically communicate with the mediation server 500. [

Specifically, the wireless communication unit 420 of the charge mediation module 400 may communicate with the mediation server 500 per unit time period and transmit the power charge amount information per unit time to the mediation server 500. If the electric vehicle 600 is fully charged, the charge mediation module 400 may be connected to the user authentication receptacle 100 to calculate the amount of electric power charged for the entire time when the electric power is supplied. Alternatively, if the charge mediation module 400 is disconnected from the user authentication receptacle 100 in the middle without completely charging the electric vehicle 600, The power charge amount transmitted to the mediation server 500 can be regarded as a power charge amount in a unit time period in which separation (i.e., communication interruption) occurs.

For example, when the unit time period is 1 minute, the power charge amount is finally transmitted to the mediation server 500 at 10 minutes after the charging, and if the charging is interrupted between 10 minutes and 11 minutes, 9 minutes and 10 minutes Can be regarded as a power charging amount between 10 minutes and 11 minutes. These considerations are based on the fact that, at the time of electric vehicle charging, 80 to 90% of the full charge amount is charged to the rated capacity and thereafter the amount of current drops sharply.

Alternatively, the unit time period may be selected arbitrarily, such as 10 minutes, 5 minutes, 30 seconds, etc. instead of 1 minute. As can be seen from the above assumption, when the electric vehicle is completely charged and separated, the electric power charge of the electric vehicle will be overestimated as the unit time period becomes longer, and as the unit time period becomes smaller, The charge amount will be calculated more accurately. Therefore, it would be ideal if power charge amount information is transmitted in real time, but there is a problem in terms of cost because the communication cost greatly increases due to the problem of data traffic and the like. Preferably, the unit time period may be one minute as in the previous example. In this case, if an electric car is charged at 3.3 kW per hour by applying the electric vehicle tariff, an average electric charge of 330 won per hour will be generated. Therefore, if you take 1 minute as a unit time period, the electricity rate per minute will be 5.5 won.

As described above in detail, according to the present invention, there is provided an electric power demand device charging system capable of stably charging a plurality of electric power demand devices while stably maintaining electric power status of the electric power aggregate building.

Further, there is an effect that a power demand device charging system capable of preventing unnecessary power consumption by using a user authentication socket that does not consume standby power while maintaining security is provided.
