Abstract

The objective of a portable fast-and-slow charge integrated charging device with a user authentication function of the present invention is to enable fast and slow charging by means of a single integrated device, thereby enhancing user convenience and efficiently supplying portable charging power while significantly reducing the cost for expanding infrastructure as well as significantly increasing charging facilities economically.

Description

Quick and slow charging integrated user authentication mobile charging device

The present invention relates to a fast and slow charging integrated user authentication mobile charging device, in which two types of outlets capable of fast charging and slow charging are configured as an integral type, and rapid charging and slow charging can be performed in a shape corresponding thereto. It relates to a portable charging device composed of two types of plugs that can be integrated.

More specifically, in the fast and slow charging integrated user authentication mobile charging device of the present invention, in charging a power demanding device that requires mobile charging, such as an electric vehicle, rapid charging and slow charging are performed by using a single outlet and a single plug. It is a device that provides optimal power supply for power demand devices while maintaining security through user authentication procedures and efficient distribution of charging current through connection to an external intermediary server. Facilities and devices for rapid charging and slow charging are separated. It relates to a fast and slow charging integrated user authentication mobile charging device capable of removing the inconvenience and inefficiency that is operated and increasing the efficiency of power operation and the convenience of use of an eco-friendly mobile charging device.

Power demand devices that need to be charged using a large amount of electricity, especially mobile power demand devices such as electric vehicles, are increasing. These power-demanding devices sometimes require that the owner of the power-demanding device receive power from a location not owned or occupied by it. For this reason, for example, for an electric vehicle, a user who allows the vehicle owner to receive power by connecting to an outlet in a place he or she does not own or live in, for example in a public electric charging station, shopping mall or apartment parking lot. Power supply devices such as outlets with built-in authentication functions, electric vehicle chargers, and connectors have been developed.

However, since these power supply devices are equipped with separate facilities for rapid charging and slow charging, users with mobile power demand devices are inconvenient to have mobile charging devices for rapid charging and slow charging at all times. There is this.

In addition, during the same time period when the user wants to charge the power demand device, rapid charging and slow charging are not efficiently allocated and set according to the power supply and demand situation, but rapid charging or slow charging depending on the components of the charging facility where the user is located. It is operated as a system that determines whether or not.

This is a relatively simple facility that can utilize the existing distribution system as it is, and does not require expansion of space or setting up a new space, and supports charging as quickly as possible by checking the power supply and demand situation in real time. There is a need to improve the simultaneous use of rapid charging and slow charging that can be built through supplementation.

In addition, the unauthorized use of power by unauthorized users, which may occur in the power supply facility, and charging systems that are unclear and prone to errors are matters that need to be improved promptly for the spread of eco-friendly electric vehicles.

In addition, the need for mobile chargers using general outlets is increasing rapidly due to the limit of the number of fixed chargers installed in aggregate buildings such as apartments, but mobile chargers are inconvenient because the charging speed is about twice as slow as the fixed slow charging.

An integrated user authentication mobile charging device for rapid and slow charging according to a preferred embodiment of the present invention is characterized in that it is configured to include an authentication outlet 100 and a mobile charger 200.

The authentication outlet 100 of the present invention includes an outlet terminal 110, an outlet control unit 120, a power relay unit 130, an outlet power supply unit 140, a micro current limiter 150, a normally closed relay, 151), characterized in that it is configured to include,

The mobile charger 200 of the present invention is characterized in that it is configured to include an authentication plug 300 and a power intermediary module 400.

At this time, the authentication plug 300 may be configured to include a plug terminal 310 and a plug power supply 320, and the plug power supply 320 includes a single-phase power plug 321 and a three-phase power plug 322 It is composed by

In addition, the power intermediary module 400 may include a charger control unit 410, a power relay metering unit 420, a wireless communication unit 430, a connector terminal 440, and a display unit 450.

As the biggest feature according to an embodiment of the present invention, the power relay unit 130 and the outlet power supply unit 140 of the authentication outlet 100, the plug power supply unit 320 of the authentication plug 300, the power intermediary The power relay metering unit 420 of the module 400 is configured to include a module that simultaneously accommodates and processes three-phase power and single-phase power.

Accordingly, an integrated charging device capable of selectively performing rapid charging and slow charging through a single facility is provided, and the selection of rapid charging and slow charging further includes a feature that is automatically determined through the outlet control unit 120 without user intervention. .

The authentication plug 300 of the mobile charger 200 of the present invention is configured to include a three-phase five-pin plug for rapid charging and a single-phase three-pin plug for slow charging in one piece.

In addition, in response to the shape of the authentication plug 300, the outlet power supply unit 140 of the authentication outlet 100 includes a three-phase five-pin type socket for rapid charging and a single-phase three-pin type socket for slow charging.

In the case of existing outlets, a 3-phase 5-pin socket for rapid charging and a single-phase 3-pin socket for slow charging are configured separately according to the characteristics of each infrastructure, such as a charging place, such as an electric vehicle charging station or an apartment building.

Accordingly, the existing mobile charger 200 also has the inconvenience of having to separately provide a 3-phase 5-pin type plug for rapid charging and a single-phase 3-pin type plug for slow charging.

Moreover, regardless of the number of users who want power demand or the type of power demanding device 600, the authentication outlet 100 is selectively installed and operated for each facility for convenience, so even in situations where there are not many users and sufficient power supply is possible, There are cases where you cannot recharge.

In addition, when the authentication outlet 100 for rapid charging and slow charging is to be operated in the same place, it is difficult to execute due to cost and space barriers because separate wiring and space beyond a specific area are required.

However, according to the present invention, while using the power line of the existing main power supply 10 as it is, the authentication outlet 100 can be configured as an integrated type supporting both three-phase and single-phase, and the user can With only the portable charger 200 equipped with the authentication plug 300, rapid charging and slow charging can be selectively operated under optimal conditions according to the power situation.

In this case, the selective operation of rapid charging and slow charging does not mean a manual mode in which a specific power source is selected according to a user's intervention.

This is to prioritize rapid charging, but taking into account the power operation status of the main power supply 10 and the power supply situation such as simultaneous access users, the charger control unit 410 and the authentication outlet 100 built into the mobile charger 200 It means that it is automatically determined by the outlet control unit 120 provided in the.

In addition, the automatic control for each power supply and demand situation as described above, includes that the user can be variably operated through the setting of a set value according to the charging system, the type of the power demanding device 600, and the future charging plan. I can.

The authentication outlet 100 according to the present invention may be externally configured including a three-phase five-pin socket and a single-phase three-pin socket arranged side by side.

In this case, the authentication outlet 100 may have a shape of a connector such as a cable that is embedded in the wall of the building or extends from the wall of the building to the outside, and there is no restriction on the shape of the location.

The authentication plug 300 according to the present invention includes a three-phase five-pin plug and a single-phase three-pin plug arranged side by side corresponding to the shape of the authentication outlet 100.

Therefore, when the authentication plug 300 is coupled to the authentication outlet 100, it may be specified that the three-phase power supply and the single-phase power supply simultaneously form a form and electrical coupling.

On the other hand, the selection of three-phase power and single-phase power is automatically performed without user intervention through the authentication procedure of the external mediation server 700 through the charger control unit 410 of the power mediation module built in the mobile charger 200. It will be described in detail through the following description of the operating principle of the present invention.

Hereinafter, a charging method using a microcurrent as an authentication power according to an embodiment of the present invention will be described as a whole, and then the order of each component including the function of the integrated charging device of the three-phase power and the single-phase power and the user authentication procedure. I will explain it as it is.

As described above, the authentication outlet 100 of the present invention includes an outlet terminal 110, an outlet control unit 120, a power relay unit 130, an outlet power supply unit 140, a microcurrent limiting device 150, a normally closed relay ( It can be configured including Normal Closed Relay, 151).

The authentication outlet 100 of the present invention determines whether or not to provide power by authenticating whether a user who wants to receive power through a power demand device 600 such as a mobile charging device has an appropriate path and qualification, and the main power supply 10 It is a power supply device with a function of supplying power to the user's power demand device 600 from.

In this case, the main power supply 10 includes, for example, a power source based on an electric vehicle charging station or an electric vehicle charging system of a collective building.

The authentication outlet 100 according to the present invention can be applied not only to an electric vehicle, but also to all power demanding devices 600 that require charging using a large amount of power, and security and billing are clarified and challenged through a user authentication procedure. Means a power supply device with a function to prevent.

In the standby state of the authentication outlet 100, that is, in the initial state, the power relay unit 130 is in an OFF state, and the micro current limiting device 150 is in an ON state.

In addition, when the authentication plug 300 is not coupled to the authentication outlet 100, since the entire circuit is not a closed loop, a minute current does not flow, and the user inserts the authentication plug 300 to the authentication outlet 100. When connected, the inside of the authentication outlet 100, which was in a disconnected state, is converted into a closed loop state in which the entire circuit is connected.

At this time, a minute current comes from the main power supply 10 and flows to the single-phase power socket 141 of the outlet power supply unit 140 through the minute current limiting device 150 in the ON state.

The minute current is used as power for authentication to authenticate the user's mobile charger 200 in the standby state.

The minute current moves to the single-phase power plug 321 of the plug power supply 320 of the mobile charger 200 through the single-phase power socket 141 of the outlet power supply unit 140, and the charger control unit of the power intermediary module 400 ( 410).

The charger control unit 410 requests the authentication outlet 100 ID information from the outlet control unit 120 of the authentication outlet 100 through a small current.

The outlet control unit 120 is driven by a micro current, which is the power for authentication, and transmits the ID of the authentication outlet 100 to the plug terminal 310 of the mobile charger 200.

The ID of the authentication outlet 100 received at the plug terminal 310 is sent to the charger control unit 410 of the power intermediary module 400, and the charger control unit 410 is an external intermediary server through the wireless communication unit 430. While transmitting the ID of the authentication outlet 100 and the ID of the portable charger 200 to 700, a password for the operation of the authentication outlet 100 and a charging current that can be used are set.

When it is determined that power supply to the user is permitted based on the ID information, the mediation server 700 transmits the operation password of the authentication outlet 100 to the authentication outlet 100 through the portable charger 200.

In addition, the intermediary server 700 checks the specifications of the power intermediary module 400 of the authentication outlet 100 and the mobile charger 200, and the type of charging current that can be supplied by the user in consideration of the power supply and demand situation. Is set.

The intermediary server 700 transmits the operation password of the authentication outlet 100 to the mobile charger 200 and at the same time transmits the type of charging current allowed to the user and a charging start command to the mobile charger 200.

The portable charger 200 transmits the authentication outlet 100 ID and charging current type received from the intermediary server 700 to the authentication outlet 100, and the outlet control unit 120 of the authentication outlet 100 connects the outlet terminal 110 ) To receive the information.

Outlet control unit 120, if the operation password of the authentication outlet 100 transmitted through the mobile charger 200 corresponds to the authentication outlet 100 ID information, the charging power is a power demand device via the mobile charger 200 ( 600).

The outlet control unit 120 first turns on the power relay unit 130 in an OFF state in order to supply power from the main power supply 10 to the power demand device 600.

At this time, the outlet control unit 120 opens a normally closed relay 151 connected to the input terminal or output terminal of the micro current limiting device 150 immediately after turning on the power relay unit 130 That is, by switching to the off state, it serves to protect by blocking the inflow of excessive amount of power to the microcurrent limiting device 150.

In addition, the outlet control unit 120 controls the power relay unit 130 based on the type of charging current received from the intermediary server 700 and a charging start command.

The power relay unit 130 selectively opens and closes the three-phase power supply and the single-phase power supply according to the type of charging current transmitted through the outlet control unit 120.

That is, if, for example, a 32A three-phase charging current for rapid charging is set and a charging command is received, the power relay unit 130 closes the three-phase switch 132 to the three-phase power socket 142. The charging current is supplied, and at the same time, the single-phase switch 131 is opened to block the flow of current through the single-phase switch 131.

Conversely, if a 16A single-phase charging current for slow charging is set and a charging command is received, the power relay unit 130 closes the single-phase switch 131 and supplies the charging current to the single-phase power socket 141, At the same time, the three-phase switch 132 is opened to block the flow of current through the three-phase switch 132.

As a third example, when a 32A single-phase charging current is set and a charging command is received, the power relay unit 130 closes the single-phase common portion of the three-phase switch 132 and the charging current through the three-phase power socket 142 Is supplied, and at the same time, the single-phase switch 131 is opened to block the flow of current through the single-phase switch 131.

The authentication plug 300 of the mobile charger 200 transmits the rapid or slow charging current received from the outlet power supply unit 140 to the connector terminal 440 through the power relay metering unit 420.

When the mobile charger 200 to which the power demand device 600 is connected is connected, the micro current limiting device 150 generates a micro current and supplies it to the mobile charger 200.

The minute current can be a low current of tens of mA or less, and is used as power for authentication. The authentication power may be used for a signal requesting the ID of the authentication outlet 100.

When the power demand device 600 is disconnected from the authentication outlet 100, the minute current limiting device 150 may be configured to no longer generate a minute current, and preferably, the power demand device 600 When the power supply procedure is in progress, the outlet control unit 120 may block the microcurrent flow to protect the microcurrent limiting device 150.

Since the minute current does not flow when the mobile charger 200 is not connected to the authentication outlet 100, standby power consumption in the authentication outlet 100 does not occur.

The microcurrent limiting device 150 can be implemented inexpensively and simply by connecting two resistors in parallel in an embodiment.

The microcurrent limiting device 150 may be implemented as a resettable fuse in another embodiment. An example of a resettable fuse is a polyswitch, an electronic device manufactured by Reychem, USA. The poly switch is in a very low resistance (0-5 ohm) state, and when overcurrent flows into the circuit, it changes to high resistance by Joule heat caused by the overcurrent. In this way, when the poly switch changes to a fixed term, the circuit is opened, and the poly switch acts like a fuse. The difference from the general fuse is that the resettable fuse becomes a low resistance state again when the cause of the overcurrent is eliminated and can be reused. In the present invention, the poly switch may be selected to have an allowable power capable of limiting the size of the microcurrent to tens of mA or less. For example, a poly switch having an allowable power of 20W or less may be selected.

On the other hand, according to this configuration, the minute current can be completely controlled, but when power for authentication is temporarily not supplied due to external shock during charging, the power relay unit 130 is turned off, but the power demanding device 600 Since large power is being charged, the amount of power has inertia and a state in which large power is to be supplied through the microcurrent limiting device 150 is in a state.

At this time, power of hundreds to thousands of times the limit power is instantaneously supplied to the microcurrent limiting device 150, and the microcurrent limiting device 150 blocks it.

However, there is a concern that the microcurrent limiting device 150 is permanently burned by a power storm that reaches hundreds to thousands of times the allowable amount, and thus cannot operate as a normal function.

Therefore, a normally closed relay 151 is additionally provided in the micro current limiting device 150, and the relay is closed, that is, while maintaining the ON state when power for control is not supplied. , When the charging power supply procedure is started, the control power is supplied to a Normal Closed Relay (151) and converted into an open state, that is, an Off state, thereby reducing the burnout of the microcurrent limiting device 150. Can be prevented.

On the other hand, even the current of several tens of mA flowing through the single-phase power socket 141 for which the use of power for authentication is terminated is completely blocked so that the three-phase power socket 142 and the single-phase power socket 141 cannot be used at the same time, thereby ensuring electrical safety. I can.

On the other hand, according to a special embodiment of the present invention,

The outlet control unit 120 operates by receiving power for authentication from the mobile charger 200.

The portable charger 200 receives a minute current from the authentication outlet 100, converts the minute current into power for authentication, and then the outlet of the authentication outlet 100 through the plug terminal 310 of the portable charger 200. It is transmitted to the terminal 110, and the outlet control unit 120 receives power for authentication through the outlet terminal 110.

Specifically, the outlet control unit 120 receives authentication power generated and transmitted under the control of the charger control unit 410 of the mobile charger 200, that is, the authentication outlet 100 ID request signal, and the authentication outlet 100 In response to the ID request signal, ID information of the authentication outlet 100 is transmitted to the plug terminal 310 through the outlet terminal 110.

Here, the authentication outlet 100 ID verification procedure, in addition to the above method, by attaching an RFID tag or an NFC tag to the authentication outlet 100, and installing an RFID reader or an NFC reader on the mobile charger 200, authentication outlet ( 100) may be performed by directly reading ID information.

In addition, when the authentication outlet 100 transmits a flexible key value together with the authentication outlet 100 ID information to the mobile charger 200, security may be further strengthened.

Meanwhile, the role of the outlet control unit 120 in the present invention is not limited to obtaining ID information of the authentication outlet 100 and opening/closing the power supply through the same, unlike the existing user authentication outlet or connector.

The outlet control unit 120 receives a set value of the charging current to be supplied to the power demand device 600 set by the intermediary server 700 through the mobile charger 200 connected to the authentication outlet 100, The authentication outlet 100 is controlled so that charging power can be supplied with the set charging current.

The outlet control unit 120 is the three-phase switch and the single-phase switch 131 of the power relay unit 130 according to the set value of the charging current received together, if the received authentication outlet 100 operation password corresponds to its ID. Adjust the open and close to ensure that suitable charging power is supplied.

That is, if a 32A 3-phase charging current for rapid charging is set in the user's power demand device, the outlet control unit 120 closes the 3-phase switch 132 so that charging power is supplied. Conversely, 16A single-phase charging for slow charging If the current is set, the outlet control unit 120 closes the single-phase switch 131 to supply charging power.

In addition, if the 32A single-phase charging current is set, the outlet control unit 120 partially closes the single-phase common portion of the three-phase switch 132 to supply charging power.

The power relay unit 130 includes a three-phase switch 132, which is a path for supplying single-phase or three-phase power, and a single-phase switch 131, which is a path for supplying single-phase power.

In the standby state, the power relay unit 130 is in an off state, and the three-phase switch 132 and the single-phase switch 131 of the power relay unit 130 are in an open state and the power supply is cut off. Keep.

The power relay unit 130, after the outlet control unit 120 receives the operation password of the authentication outlet 100 and the set value of the charging current to be supplied from the external mediation server 700, under the control of the outlet control unit 120 It can be driven.

That is, when the outlet control unit 120 turns on the power relay 130 according to the set value of the charging current and transmits a signal corresponding to the set value of the corresponding charging current, the three-phase switch 132 or the single-phase switch As 131 is closed, the circuit is connected to supply power.

After the three-phase switch 132 or the single-phase switch 131 of the power relay unit 130 is once closed, the DC power supplied from the plug terminal 310 or a part of the AC power supplied from the main power supply 10 is used. , It is possible to keep the three-phase switch 132 or the single-phase switch 131 closed. As an example, AC power may be used to control the three-phase switch 132 or the single-phase switch 131 according to the specifications of the three-phase switch 132 or the single-phase switch 131, in this case, the main power supply 10 Since it is possible to keep the three-phase switch 132 or the single-phase switch 131 closed by using a part of the AC power from, a separate AC/DC converter for this may not be required.

In other words, the outlet control unit 120 is operated by DC power, but compared to this, after the three-phase switch 132 or the single-phase switch 131 receives DC power from the outside and is triggered, it is driven by AC power. Can be maintained.

When the three-phase switch 132 or the single-phase switch 131 is kept closed by using the DC power supplied from the outlet terminal 110, when the mobile charger 200 is separated from the authentication outlet 100, the plug Since DC power for controlling the three-phase switch 132 or the single-phase switch 131 is not supplied from the terminal 310, the three-phase switch 132 or the single-phase switch 131 is opened.

On the contrary, when the three-phase switch 132 or the single-phase switch 131 is kept closed by using a part of the AC power supplied from the main power supply 10, the mobile charger 200 is separated from the authentication outlet 100. At this time, the circuit to which the main power supply 10 is supplied is opened so that AC power cannot be supplied from the main power supply 10 any more, so that the three-phase switch 132 or the single-phase switch 131 is opened.

In addition, when the mobile charger 200 is separated from the authentication outlet 100, when the DC power is triggered and then the operation is maintained with the main power, the periodic oscillation of DC power or other signals is detected, and periodic oscillation occurs. It can be turned off when the undetected limit set time is exceeded.

Meanwhile, the power relay unit 130 may be configured to include three types of switchgear such as a single-phase switch for 16A 131, a three-phase switch for 32A 132, and a common single-phase part of the three-phase switch for 32A 132. have.

This is for the case of the power demand device 600, which uses single-phase power, but has a 5-pin plug, that is, each having a single-phase 3-pin type, 3-phase 5-pin type, and single-phase 5-pin type plug. This is to maintain compatibility while coping with power supply to all of the power demanding devices 600.

At this time, the 16A single-phase switch 131 is connected to a single-phase power socket 141 having a single-phase 3-pin type, and the 32A three-phase switch 132 is a three-phase power socket 142 having a three-phase 5-pin type. It is connected to two phases (for example, S(L2), T(L3)), and the single-phase common part of the three-phase switch 132 for 32A is one phase of the three-phase power socket 142 (for example, R (L1)).

In this case, the neutral wire is connected only to the single-phase common portion of the 16A single-phase switch 131 and the 32A three-phase switch 132. The ground wire is always connected to all power sockets.

Therefore, in the case of supplying charging power to the 32A three-phase power supply for rapid charging, that is, the three-phase power socket 142, the three-phase power supply must be connected by closing the 32A three-phase switch 132 as a whole. 142).

In addition, in the case of the power demand device 600 based on power charging with a large capacity by using a single-phase power supply but having a 5-pin type, the 16A single-phase switch 131 and the 32A three-phase switch 132 are opened. It is characterized in that charging power is supplied through the three-phase power socket 142 only in a state in which the single-phase common portion of the 32A three-phase switch 132 is kept closed without an additional closing operation in the state.

The mobile charger 200 of the present invention has one end connected to the authentication outlet 100 and the other end connected to a power demand device 600 such as an electric vehicle, and the authentication plug 300 and the power intermediary module 400 It consists of including.

The authentication plug 300 includes a plug terminal 310 and a plug power supply 320, and the power intermediary module 400 includes a charger control unit 410, a power relay metering unit 420, a wireless communication unit 430, and a connector It may be configured to include a terminal 440 and a display unit 450.

The plug power supply unit 320 of the authentication plug 300 is composed of a single-phase power plug 321 and a three-phase power plug 322, and externally, a single-phase 3-pin plug and a 3-phase 5-pin plug are provided integrally, It has a shape corresponding to the single-phase power socket 141 (single-phase 3-pin socket) and the 3-phase power socket 142 (3-phase 5-pin socket) of the outlet power supply unit 140 of the authentication outlet 100.

The authentication plug 300 generates a minute current while being coupled to the authentication outlet 100, and the plug terminal 310 transmits the minute current received from the authentication outlet 100 as power for authentication to the authentication outlet 100. Functions.

In addition, the plug terminal 310 of the authentication plug 300 receives the authentication outlet 100 ID information from the authentication outlet 100 and provides it to the charger control unit 410, and the plug power supply unit 320 is supplied from the main power supply 10. It serves as a path for providing the provided charging power to the power demanding device 600 via the power relay metering unit 420 of the power intermediary module 400.

Meanwhile, the plug terminal 310 of the authentication plug 300 may be connected to the outlet terminal 110 of the authentication outlet 100 by wire or wirelessly according to an embodiment of the present invention.

For example, the plug terminal 310 is implemented in the form of a wireless power transmission and information transmission unit capable of wirelessly transmitting power for authentication to the outlet terminal 110 and transmitting and receiving information with the outlet terminal 110 wirelessly. Can be.

Correspondingly, in the case of wireless connection, the outlet terminal 110 wirelessly receives power for authentication from the plug terminal 310, and wireless power reception and information transmission and reception capable of wirelessly transmitting and receiving information with the plug terminal 310 It can be implemented in the form of a unit.

In the case of the wireless information transmission and reception unit, it can be used in combination of one or more of an electromagnetic wave type and an optical type.

The charger control unit 410 supplies power for authentication to the outlet control unit 120, requests and receives the authentication outlet 100 ID information, and obtains the set value of the authentication outlet 100 operation code and charging current from the intermediary server 700. Control.

In addition, the charger control unit 410 functions to supply charging power to the power demand device 600 and to transmit information necessary for charging processing for power use to the intermediary server 700.

On the other hand, the charger control unit 410 is configured to download the password of the authentication outlet 100 to be used next time from the intermediary server 700 at the end of the authentication sequence, transfer it to the outlet control unit 120, and store the password according to an embodiment of the present invention. Can be. With this configuration, it is possible to prevent password leakage due to the use of a fixed password.

That is, since the intermediary server 700 and the outlet control unit 120 can compare the floating passwords with each other, charging cannot be started unless a new password to be used next time is input, and accordingly, the function of preventing password leakage can be strengthened.

Alternatively, according to another embodiment of the present invention, the password for operation of the authentication outlet 100 may be obtained from a database built in the mobile charger 200 or the power demanding device 600.

However, when the number of authentication outlets 100 increases, it may be difficult to store all authentication outlets 100 operating passwords inside the portable charger 200 or the power demanding device 600. Therefore, it is preferable to configure the mobile charger 200 to obtain the authentication outlet 100 operation password from the externally located intermediary server 700 through the wireless communication unit 430 in the process of obtaining the authentication outlet 100 operation password.

In this way, if the authentication outlet 100 operation password is obtained from the outside, the risk of leakage of the entire authentication outlet 100 operation password, which may occur when the intermediary server 700 is provided and not separately managed, can be reduced.

The power relay metering unit 420 opens and closes the power supplied from the authentication outlet 100 via the plug power supply unit 320 and measures the amount of power. The metered power is supplied to the power demand device 600 connected to the mobile charger 200 by the connector 500.

In addition, the measured power amount information is transmitted to the charger control unit 410, and the mediation server 700 through wireless communication via the wireless communication unit 430 based on the amount of power measured under the control of the charger control unit 410. Information on the amount of power charged to the power demanding device 600 is transmitted.

The display unit 450 may be included in the mobile charger 200 or may be provided as a separate external product.

The display unit 450 may display a communication status and a charging status between the mobile charger 200 and the mediation server 700.

In this case, the communication state means a data transmission/reception state between the mobile charging device and the intermediary server 700, and transmits the ID of the authentication outlet 100 and whether it is normally received, and transmits the operation password of the authentication outlet 100. And whether or not normal reception, a charging current set value allocated to the mobile charging device from the intermediary server 700, power charging cost, and the like.

In addition, the charging situation may include a charging step performed in real time, a charging remaining amount, a charging speed, and a classification of charging power.

On the other hand, according to an embodiment of the present invention, the connector 500 for connection to the power demand device 600, such as an electric vehicle, and the power intermediary module 400 of the mobile charger 200 may be implemented in an integrated form. I can.

According to this embodiment, since the power intermediary module 400 is embedded in the connector 500, the risk of damage, flooding, theft, and the like of the power intermediary module 400 may be reduced. In addition, a mechanical and electronic locking device for preventing theft may be incorporated in the power intermediary module 400 in the form of the connector 500.

In addition, according to another embodiment of the present invention, the authentication plug 300 and the power intermediary module 400 may be implemented in a mutually independent form using a cable or an intermediate connector. In this case, for charging, the user may connect the authentication plug 300 to the power intermediary module 400 and then connect the authentication plug 300 to the authentication outlet 100.

On the other hand, the power intermediary module 400 is built in a power demand device represented by an electric vehicle, and the internal battery diagram 461 may also be replaced with an existing battery of the power demand device 600.

On the other hand, according to a special embodiment of the present invention, the power of the smart device may be used as the power for authentication through the USB terminal 111 without using a microcurrent as power for authentication.

This can be implemented by providing a USB terminal 111 in the authentication outlet 100 and connecting a user's smart device to the USB terminal 111.

In this case, the minute current becomes unnecessary, and thus the minute current limiting device 150 may not be used. By using this, in place of the mobile charger 200 of FIG. 2, an In-Cable Control and Protection Device (ICCPD) having a plug power supply unit 320, a power relay, and a connector terminal 440 as main components is used. It can also be charged.

In step S250, the smart device obtains the operation password of the authentication outlet 100 from the intermediary server 700, and transmits it to the authentication server.

In step S260, a process of transmitting the charging current, charging time, and amount of charging for the user's power demand device 600 set by the intermediary server 700 to the authentication outlet 100 by the smart device is performed.

In step S270, by closing the three-phase or single-phase switch 131 suitable for the charging current received from the authentication outlet 100, a preparation process for supplying the corresponding power from the main power to the power demanding device 600 of the user is performed.

In step S280, a process of connecting the authentication plug 300 to the authentication outlet 100 and connecting the power demanding device 600 and the connector 500 is performed.

In step S290, as power supply is started, charging of the power demanding device 600 is started.

On the other hand, according to another special embodiment of the present invention, without using a minute current as power for authentication, an internal battery 461 is provided inside the power intermediary module, and the power of the internal battery 461 is used for authentication. Can be used with electric power.

3 is a view showing a state in which the internal battery 461 and the battery management unit 460 are provided in the power intermediary module, and FIG. 6 is a flowchart illustrating a process of using the internal battery 461 as power for authentication.

A procedure for using the internal battery 461 as power for authentication will be described with reference to FIGS. 3 and 6 as follows.

In step S300, a process of connecting the authentication plug 300 to the authentication outlet 100 and connecting the power demand device 600 and the connector 500 is performed.

In step S310, a process of supplying power for generating power for authentication from the internal battery 461 of the power intermediary module 400 of the mobile charger 200 to the authentication outlet 100 is performed.

In step S320, the authentication outlet 100 is driven through the authentication power in step S110, and the power intermediary module 400 acquires the ID of the authentication outlet 100 is performed.

In step S330, a process of transmitting the authentication outlet 100 ID and the ID of the mobile charger 200 to the intermediary server 700 through the wireless communication unit 430 by the power intermediary module 400 is performed.

In step S340, a process of transmitting the authentication outlet 100 operation password to the power intermediary module 400 by the intermediary server 700 is performed.

In step S350, a process of checking the specifications of the authentication outlet 100 and the power intermediary module 400 in the intermediary server 700 is performed.

In step S360, a process of setting a charging current to be supplied to the user's power demanding device 600 from the mediation server 700 and transmitting a charging start command is performed.

In step S370, a process of supplying charging power from the main power supply 10 by closing a single-phase or three-phase switch suitable for the charging current set by the intermediary server 700 in the authentication outlet 100 is performed.

In step S380, as power supply is started, charging of the power demanding device 600 is started.

In the charging process of the power demand device 600 described above, in some cases, the allowable current amount of the authentication outlet 100 may be different due to restrictions due to a transmission line or the like. In preparation for this case, it is necessary to provide information on the allowable current amount of the authentication outlet 100 by graded.

As a specific method of providing, first, the authentication outlet 100 directly provides the permitted current amount information to the mobile charger 200 through the authentication outlet 100 ID information, and second, the authentication outlet 100 corresponds to the ID information. There is a method of storing the allowable current amount information of the authentication outlet 100 in the intermediary server 700 and receiving the stored allowable current amount information from the intermediary server 700 during the authentication process by the mobile charger 200.

On the other hand, according to another special embodiment of the present invention, according to the mutual authentication of the authentication outlet 100 and the mobile charger 200, a current greater than a designated allowable current may be selectively flowed according to the external dimension standard of the plug and the outlet. .

Depending on the development of materials and monitoring technology, it is possible to make a large current flow, but the allowable current, which was limited to distinguish the appearance, can be set upward. In this case, by adding a temperature sensor and a buzzer to the authentication outlet 100, a warning sound may be generated according to the temperature increase, and the power supply may be cut off by operating an electronic switch.

According to an embodiment of the present invention, when the authentication procedure is performed using a minute current flowing by the operation of connecting the mobile charger 200 to the authentication outlet 100, the mobile charger 200 does not have its own battery. You don't have to.

Furthermore, since the micro current limiting device 150 is used to limit the magnitude of the micro current, most electric devices including mobile phone chargers and electric razors are connected to the authentication outlet 100 without going through the authentication procedure. Cannot receive

Specifically, when not authenticated (ie, before the authentication procedure), the maximum value of the minute current in the authentication outlet 100 may be, for example, 10 mA. Therefore, for example, when connecting a heater with a rated power of 3,000W to the authentication outlet 100, only a maximum of 2.2W (220V*10mA=2.2W) can be supplied, so before going through the authentication procedure, the heater Cannot be used at all.

As another example, in the case of a smartphone charger, a current of 0.15A is required, but the maximum value of the microcurrent provided by the authentication outlet 100 is, for example, only 10mA, so the smartphone charger can be used at all before the authentication procedure. none.

In other words, the small amount of current (10mA) has a sufficient size as an authentication power source for the authentication process, but even an electric device with a small power consumption such as a smartphone charger cannot be used in reality with such a small amount of current. Even if the electricity corresponding to the maximum value of the microcurrent is used without permission throughout the month, the amount of electricity is only 220V * 0.01A * 24 hours * 31 days = 1.63 kWh, which is less than 200 won when converted into an amount.

In addition, according to an embodiment of the present invention, a minute current flows only when the mobile charger 200 is connected to the authentication outlet 100, and when the mobile charger 200 is separated from the authentication outlet 100, the power relay Since the unit 130 is opened, current no longer flows from the main power supply 10 to the mobile charger 200 through the outlet power supply unit 140 of the authentication outlet 100 and the plug power supply unit 320 of the mobile charger 200.

When the portable charger 200 is not connected to the authentication outlet 100, a minute current does not flow. Therefore, the parts for user authentication do not consume power, that is, standby power, during the standby operation of the authentication outlet 100. .

As a result, there is no problem of inconsistency between a person (eg, a building owner, etc.) and an actual user (eg, an electric vehicle owner) who pay for standby power.

In addition, according to another embodiment of the present invention, the mobile charger 200 may not have its own battery. In this case, when the mobile charger 200 is separated from the authentication outlet 100, the mobile charger 200 is Since it is no longer possible to transmit power charge amount information to the mediation server 700, a problem related to this may occur.

To solve this, the wireless communication unit 430 of the mobile charger 200 may be configured to periodically communicate with the mediation server 700.

Specifically, the wireless communication unit 430 of the mobile charger 200 may communicate with the mediation server 700 every unit time period to transmit power charge amount information per unit time to the mediation server.

If the power demand device 600, for example, the electric vehicle is fully charged, the mobile charger 200 is connected to the authentication outlet 100 to calculate the amount of power charged for the entire time when power is supplied.

However, in contrast, when the electric vehicle is not fully charged and the mobile charger 200 is separated from the authentication outlet 100 in the middle, the intermediary server 700 in the last unit time period before separation (ie, before communication interruption). The amount of power charge transmitted to the device can be regarded as the amount of power charge in the unit time period in which separation (ie, communication interruption) occurred.

For example, when the unit time period is 1 minute, the power charge amount is finally transmitted to the mediation server 700 when 10 minutes have elapsed after charging, and if charging is stopped between 10 and 11 minutes, between 9 and 10 minutes You can consider the amount of power charge in the power supply between 10 and 11 minutes. This consideration is based on the fact that when an electric vehicle is charged, up to 80 to 90% of the full charge is charged to the rated capacity, and then the amount of current drops rapidly.

In contrast, the unit time period may be arbitrarily selected, such as 10 minutes, 5 minutes, and 30 seconds instead of 1 minute. If the electric vehicle is not fully charged and separated in the middle, as can be seen from the previous assumption, the electric vehicle's power charge will be excessively calculated as the unit time period increases, and the electric vehicle's power as the unit time period decreases. The filling amount will be calculated more accurately.

Therefore, it would be ideal if the power charge amount information was transmitted in real time, but there is a problem in terms of cost because communication cost increases significantly due to problems such as data communication amount.

Preferably, the unit time period may be 1 minute as in the previous example. In this case, if an electric vehicle is charged at 3.3kW per hour by applying the electric vehicle electric rate plan, an average of 330 won per hour is incurred. Therefore, if 1 minute is a unit time period, the electricity bill per minute is 5.5 won.

As described in detail above, according to the present invention, there is an effect of providing a charging system capable of stably charging a plurality of power demanding devices 600 while stably maintaining the power situation of the main power supply 10.

In addition, there is an effect of providing a charging system for the power demand device 600 that can prevent unnecessary power consumption by using the authentication outlet 100 that does not consume standby power while maintaining security.

In addition, there is an effect of providing a charging system for the power demand device 600 capable of simplifying and automating the billing process for power use related to the charging of the power demand device 600.

In addition, a charging system capable of improving user convenience is provided by adaptively responding to changes in the power situation of the main power supply 10, automatically performing the charging stop and resume operation for the power demanding device 600 without user intervention. Has the effect of being.

On the other hand, in the case of supplying high power according to the charging of the power demanding device 600, there is a risk of fire due to heat generation at the internal terminals of the authentication outlet 100 and the mobile charger 200. In order to cope with this, the charging power supply section between the power relay unit 130 of the authentication outlet 100 and the outlet power supply unit 140, the plug power supply unit 320 and the power relay metering unit 420 of the mobile charger 200, and By additionally providing a temperature sensor in the charging power supply section between the connector terminals 440, the charging amount can be controlled (charger control unit 410, outlet control unit 120) or stop charging by measuring the temperature of the heating part.

Meanwhile, the charging-related technology used in the present invention can be applied in an equivalent manner to discharge such as V2G (Vehicle To Grid) according to the power demand and supply conditions. The discharge current can be set and supplied to the house and the grid in the same way as the charging current setting, and for the power transmitted in the reverse direction, the discharge cost can be paid from a power company or the like according to the amount of power.

The embodiments of the present invention described above are merely exemplary, and those of ordinary skill in the art to which the present invention pertains will appreciate that various modifications and other equivalent embodiments are possible.

Therefore, it will be appreciated that the present invention is not limited to the form mentioned in the detailed description above. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.

In addition, the present invention is to be understood as including the spirit of the present invention as defined by the appended claims and all modifications, equivalents and substitutes within the scope thereof.
