Description

{User Authenticating mobile charging apparatus with fast and slow charging integral}

The present invention relates to a user-certified mobile charging device integrated with fast and slow charging, which is composed of two types of outlets that can perform fast charging and slow charging, and has a corresponding shape for fast charging and slow charging. This relates to a mobile charging device that integrates two types of plugs.

More specifically, the rapid and slow charging integrated user authentication mobile charging device of the present invention is used for charging power demand devices that require mobile charging, such as electric vehicles, for fast charging and slow charging using a single outlet and a single plug. It is a device that maintains security through user authentication procedures through connection to an external mediation server and efficient distribution of charging current while simultaneously supplying power optimized for power demand devices. The facilities and devices for fast charging and slow charging are separated. This is about a user-certified mobile charging device integrated with fast and slow charging that can eliminate inconvenience and inefficiency in operating the device and rapidly increase the efficiency of power operation and the convenience of using an eco-friendly mobile charging device.

Power demand devices that need to be charged using large amounts of electricity, especially mobile power demand devices such as electric vehicles, are increasing. These power demand devices sometimes require the owner of the power demand device to receive power from a location other than his/her own or residence. For this reason, for example, for electric vehicles, users are encouraged to connect the vehicle to an outlet and receive power in locations other than the vehicle's own or residence, for example at a public electric charging station, in a shopping mall or in an apartment complex. Power supply devices such as outlets with built-in authentication functions, electric vehicle chargers, and connectors have been developed.

However, these power supply devices are operated with separate facilities for fast charging and slow charging, so users who own mobile power demand devices face the inconvenience of having to always have portable charging devices for fast charging and slow charging. There is.

Moreover, at the same time when the user wants to charge the power demand device, fast charging and slow charging are not efficiently distributed and set according to the power supply and demand situation, but fast charging or slow charging is activated depending on the components of the charging facility where the user is located. It is operated as a system that determines whether or not.

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

In addition, unauthorized power use by unauthorized users that may occur in the above-mentioned power supply facilities, unclear and error-prone billing systems, etc. are also matters that must be quickly improved for the spread of eco-friendly electric vehicles.

In addition, due to the current limit on the number of fixed chargers installed in complex buildings such as apartments, the need for mobile chargers using regular outlets is rapidly increasing, but the charging speed of mobile chargers is about twice as slow as that of fixed slow charging, which is inconvenient.

A user authentication mobile charging device with integrated rapid and slow charging according to a preferred embodiment of the present invention is characterized by comprising 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 unit 140, a micro current limiting device 150, a normally closed relay, 151), and is characterized in that it includes

The mobile charger 200 of the present invention is characterized in that it includes an authentication plug 300 and a power brokering module 400.

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

In addition, the power brokering module 400 may be configured to 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.

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

As a result, an integrated charging device capable of selectively fast charging and slow charging is provided through a single facility, and the selection of fast charging and slow charging 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 5-pin plug for rapid charging and a single-phase 3-pin plug for slow charging in an integrated form.

In addition, corresponding to the shape of the authentication plug 300, the outlet power unit 140 of the authentication outlet 100 is configured to include a three-phase 5-pin type socket for fast charging and a single-phase 3-pin type socket for slow charging in an integrated form.

In the case of existing outlets, three-phase 5-pin sockets for fast charging and single-phase 3-pin sockets for slow charging are configured separately according to the characteristics of each infrastructure, such as charging locations, such as electric vehicle charging stations or complex buildings such as apartments.

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

In addition, regardless of the number of users who want to demand power or the type of power demand device 600, authentication outlets 100 are installed and operated selectively for convenience at each facility, so even in situations where the number of users is not large and sufficient power supply is possible, rapid There may be cases where charging is not possible.

In addition, when attempting to operate the authentication outlet 100 for fast charging and slow charging in the same place, separate wiring and space beyond a specific area are required, making it difficult to implement due to cost and space barriers.

However, according to the present invention, the authentication outlet 100 can be configured as an integrated type supporting both three-phase and single phase while using the power line of the existing main power supply 10, and the user can use the integrated authentication outlet 100 corresponding to the integrated authentication outlet 100. Only the mobile charger 200 equipped with the authentication plug 300 can selectively operate fast charging and slow charging under optimal conditions depending on the power situation.

At this time, selective operation of fast charging and slow charging does not mean a manual mode in which a specific power source is selected through user intervention.

This gives priority to fast charging, but considering the power operation status of the main power source 10 and the availability of power such as simultaneous access users, the charger control unit 410 and the authentication outlet 100 built into the mobile charger 200 This means that it is automatically determined by the outlet control unit 120 provided in.

In addition, the automatic control according to the power supply and demand situation as described above may be configured to include the user being able to operate variably through setting values in advance according to the charging system, type of power demand device 600, future charging plan, etc. You can.

The authentication outlet 100 according to the present invention may be externally configured to include a three-phase 5-pin socket and a single-phase 3-pin socket arranged side by side.

At this time, the authentication outlet 100 may be built into the wall of the building or may have the shape of a connector such as a cable extending externally from the wall of the building, and there are no restrictions on the shape of the location.

The authentication plug 300 according to the present invention is configured to include a three-phase 5-pin plug and a single-phase 3-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 can be specified that three-phase power and single-phase power are simultaneously morphologically and electrically coupled.

Meanwhile, the selection of three-phase power and single-phase power is made automatically without user intervention through the authentication process of the external mediation server 700 through the charger control unit 410 of the power mediation module built into the mobile charger 200. This will be described in detail through the following description of the operating principle of the present invention.

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

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 unit 140, a micro current limiting device 150, and a normally closed relay ( It can be configured to include Normal Closed Relay, 151).

The authentication outlet 100 of the present invention determines whether to provide power by authenticating whether the user who wishes to receive power through the power demand device 600, such as a mobile charging device, has an appropriate route and qualifications, and determines whether to provide power to the main power source 10. It is a power supply device with the function of supplying power from the user's power demand device 600.

At this time, the main power source 10 includes, for example, a power source such as an electric vehicle charging station or an electric vehicle charging system in a complex building.

The authentication outlet 100 according to the present invention can be applied not only to electric vehicles but also to all power demand devices 600 that require charging using a large amount of power, and clarifies security and billing and eliminates challenges through the user authentication process. It refers to a power supply device with a function to prevent

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

In addition, when the authentication plug 300 is not coupled to the authentication outlet 100, a small current does not flow because the entire circuit is not a closed loop, and the user connects 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 to a closed loop state in which the entire circuit is connected.

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

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

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

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

The outlet control unit 120 is driven by a small current, which is 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 brokerage module 400, and the charger control unit 410 is sent to an external brokerage server through the wireless communication unit 430. The ID of the corresponding authentication outlet 100 and the ID of the mobile charger 200 are transmitted to (700), and the operation password of the authentication outlet 100 and the usable charging current setting are requested.

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

In addition, the mediation server 700 checks the specifications of the power mediation module 400 of the authentication outlet 100 and the mobile charger 200, and considers the power supply and demand situation to determine the type of charging current that the user can receive. Set .

The mediation server 700 transmits the operating password of the authentication outlet 100 to the mobile charger 200 and simultaneously transmits the type of charging current permitted to the user and a charging start command to the mobile charger 200.

The mobile charger 200 transmits the authentication outlet 100 ID and charging current type transmitted from the mediation server 700 to the authentication outlet 100, and the outlet control unit 120 of the authentication outlet 100 connects the outlet terminal 110 to the authentication outlet 100. ) and receive the relevant information through.

If the operation password of the authentication outlet 100 received through the mobile charger 200 corresponds to the ID information of the authentication outlet 100, the outlet control unit 120 transmits the charging power to the power demand device (power demand device) through the mobile charger 200. 600).

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

At this time, immediately after turning on the power relay unit 130, the outlet control unit 120 opens the normally closed relay (151) connected to the input terminal or output terminal of the micro current limiting device 150. In other words, by switching to the off state, it serves to protect the small current limiting device 150 by blocking excessive power from flowing into it.

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

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

That is, for example, if a 32A 3-phase charging current for rapid charging is set and a charging command is received, the power relay unit 130 closes the 3-phase switch 132 and connects the 3-phase power socket 142 to the 3-phase power socket 142. 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 to supply 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 part of the three-phase switch 132 and supplies the charging current to the three-phase power socket 142. supplies and at the same time opens the single-phase switch 131 to block the flow of current through the single-phase switch 131.

The authentication plug 300 of the mobile charger 200 transmits the fast or slow charging current received from the outlet power 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, the micro current limiting device 150 generates a micro current and supplies it to the mobile charger 200.

Microcurrent can be a low current of tens of mA or less, and is used as power for authentication. 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 micro-current limiting device 150 may be configured to no longer generate micro-current, preferably for the power demand device 600. When the power supply procedure proceeds, the outlet control unit 120 may block the flow of micro current to protect the micro current limiting device 150.

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

In one embodiment, the micro-current limiting device 150 can be implemented inexpensively and simply by connecting two resistors in parallel.

In another embodiment, the micro-current limiting device 150 may be implemented as a resettable fuse. An example of a resettable fuse is polyswitch, an electronic device manufactured by Reychem in the United States. The poly switch is in a very low resistance state (0 to 5 ohms), but when overcurrent flows into the circuit, it changes to high resistance due to Joule heat caused by the overcurrent. In this way, when the poly switch changes to a fixed state, the circuit is opened and the poly switch acts like a fuse. The difference from a typical fuse is that a resettable fuse returns to a low-resistance state when the cause of the overcurrent is removed and can be reused. In the present invention, the poly switch can be selected to have an allowable power that can limit the size of microcurrent to tens of mA or less. For example, a poly switch with an allowable power of 20W or less may be selected.

Meanwhile, according to this configuration, microcurrent can be completely controlled, but if power for authentication is not temporarily supplied due to external shock or the like during charging, the power relay unit 130 is turned off, but the power demand device 600 Because large power is being charged, the amount of power has inertia and is in a state where large power is desired to be supplied through the micro current limiting device 150.

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

However, there is a risk that the micro-current limiting device 150 may be permanently damaged by a power storm that is hundreds to thousands of times the allowable amount, making it unable to operate normally.

Therefore, the micro current limiting device 150 is additionally equipped with a Normal Closed Relay (151), and in normal times when control power is not supplied, the relay maintains a closed, i.e., on, state. , When the charging power supply procedure is initiated, power for control is supplied to the Normal Closed Relay (151) and converted to an open, that is, Off state, thereby preventing burnout of the micro current limiting device (150). It can be prevented.

Meanwhile, electrical safety can be ensured by completely blocking even tens of mA of current flowing in the single-phase power socket (141) whose power use for authentication has ended, preventing the three-phase power socket (142) and single-phase power socket (141) from being used at the same time. You can.

Meanwhile, 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 mobile charger 200 receives a micro-current from the authentication outlet 100, converts this micro-current into power for authentication, and then connects the outlet of the authentication outlet 100 through the plug terminal 310 of the mobile 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 the authentication power generated and delivered under the control of the charger control unit 410 of the mobile charger 200, that is, the authentication outlet 100 ID request signal, and receives the authentication outlet 100 ID request signal. In response to the ID request signal, the authentication outlet 100 ID information 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, attaches an RFID tag or NFC tag to the authentication outlet 100 and installs an RFID reader or NFC reader on the mobile charger 200, so that the authentication outlet ( It may also be performed by directly reading ID information from 100).

Additionally, when the authentication outlet 100 transmits a dynamic key value along with the authentication outlet 100 ID information to the mobile charger 200, security can be further strengthened.

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

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

If the received operation password of the authentication outlet 100 corresponds to its ID, the outlet control unit 120 operates the three-phase switch and the single-phase switch 131 of the power relay unit 130 according to the setting value of the charging current received together. Adjust Open and Close to ensure appropriate charging power is supplied.

That is, if a 32A three-phase charging current for rapid charging is set in the user's power demand device, the outlet control unit 120 closes the three-phase switch 132 to supply charging power, and 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 32A single-phase charging current is set, the outlet control unit 120 partially closes the single-phase common part of the three-phase switch 132 to supply charging power.

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

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

That is, when the power relay unit 130 is turned on in the outlet control unit 120 according to the set value of the charging current and a signal corresponding to the set value of the charging current is transmitted, the three-phase switch 132 or the single-phase switch When (131) is closed, the circuit is connected and power is supplied.

Once the three-phase switch 132 or the single-phase switch 131 of the power relay unit 130 is closed, a portion of the direct current power supplied from the plug terminal 310 or the alternating current power supplied from the main power source 10 is used. , the three-phase switch 132 or the single-phase switch 131 can be maintained closed. As an example, depending on the specifications of the three-phase switch 132 or the single-phase switch 131, AC power can be used to control the three-phase switch 132 or the single-phase switch 131, and in this case, the main power supply 10 Since the three-phase switch 132 or the single-phase switch 131 can be kept closed by using a part of the AC power from, a separate AC/DC converter for this may not be necessary.

In other words, the outlet control unit 120 is operated by direct current power, but in contrast, after the three-phase switch 132 or the single-phase switch 131 is triggered by receiving direct current power from the outside, it is driven by alternating current power. This can be maintained.

When the three-phase switch 132 or the single-phase switch 131 is kept closed using direct current power supplied from the outlet terminal 110, when the mobile charger 200 is disconnected from the authentication outlet 100, the plug Since direct current power to control 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.

In contrast, when maintaining the closure of the three-phase switch 132 or the single-phase switch 131 using a portion of the AC power supplied from the main power supply 10, the mobile charger 200 is separated from the authentication outlet 100. When this happens, the circuit to which the main power source 10 is supplied is opened and AC power can no longer be supplied from the main power source 10, so 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 triggering DC power and then maintaining operation with main power, periodic oscillation of DC power or other signals is detected and periodic oscillation is detected. It can be turned off when the undetected limit setting time is exceeded.

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

This is for the case where, among the power demand devices 600, the power used is single-phase power, but the external appearance is provided with a 5-pin plug, that is, each device is equipped with a single-phase 3-pin type, three-phase 5-pin type, and single-phase 5-pin type plug. This is to enable power supply to all power demand devices 600 while maintaining compatibility.

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

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

Therefore, when supplying charging power to a 32A 3-phase power source for rapid charging, that is, the 3-phase power socket 142, the 32A 3-phase switch 132 must be completely closed and connected to ensure that the 3-phase power is connected to the 3-phase power socket ( 142).

In addition, in the case of the power demand device 600 that uses a single-phase power source but has a 5-pin type and is based on high-capacity power charging, the single-phase switch 131 for 16A and the three-phase switch 132 for 32A are open. It is characterized in that charging power is supplied through the three-phase power socket (142) only by maintaining the single-phase common part of the three-phase switch (132) for 32A closed without any additional closing operation in this state.

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

The authentication plug 300 includes a plug terminal 310 and a plug power unit 320, and the power brokering 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 unit 320 of the authentication plug 300 is composed of a single-phase power plug 321 and a three-phase power plug 322. Externally, the single-phase 3-pin plug and the three-phase 5-pin plug are provided in an integrated form, It has a shape corresponding to the single-phase power socket 141 (single-phase 3-pin socket) and the three-phase power socket 142 (3-phase 5-pin socket) of the outlet power unit 140 of the authentication outlet 100.

The authentication plug 300 generates a micro-current when coupled to the authentication outlet 100, and the plug terminal 310 uses the micro-current received from the authentication outlet 100 as authentication power and transmits it to the authentication outlet 100. It functions.

In addition, the plug terminal 310 of the authentication plug 300 receives authentication outlet 100 ID information from the authentication outlet 100 and provides it to the charger control unit 410, and the plug power unit 320 receives the authentication outlet 100 ID information from the main power source 10. It serves as a passage to provide the provided charging power to the power demand device 600 through the power relay metering unit 420 of the power brokering 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 and reception unit that can wirelessly transmit power for authentication to the outlet terminal 110 and transmit and receive information with the outlet terminal 110 wirelessly. It can be.

Correspondingly, in the case of a wireless connection, the outlet terminal 110 wirelessly receives power for authentication from the plug terminal 310, and wirelessly receives power and information that can transmit and receive information to and from the plug terminal 310. It can be implemented in the form of a unit.

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

The charger control unit 410 supplies power for authentication to the outlet control unit 120, requests and receives authentication outlet 100 ID information, and obtains the operation password and charging current settings of the authentication outlet 100 from the mediation server 700. control.

In addition, the charger control unit 410 supplies charging power to the power demand device 600 and transmits information necessary for billing for power use to the mediation server 700.

Meanwhile, according to an embodiment of the present invention, the charger control unit 410 is configured to download the authentication outlet 100 password to be used next time at the end of the authentication sequence from the mediation server 700 and transmit it to the outlet control unit 120 to store it. It can be. If configured in this way, password leakage due to use of a fixed password can be prevented.

That is, because the mediation server 700 and the outlet control unit 120 can compare the dynamic passwords, charging cannot be started unless a new password to be used next time is input, thereby strengthening the password leak prevention function.

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

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

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

The power relay metering unit 420 opens and closes the power supplied from the authentication outlet 100 via the plug power 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 through the connector 500.

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

The display unit 450 may be built into the mobile charger 200 or may be provided as a separate external component.

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

In this case, the communication status refers to the status of data transmission and reception between the mobile charging device and the mediation server 700, including transmission of the ID of the authentication outlet 100, whether or not the reception is normal, and transmission of the operating password of the authentication outlet 100. It may include normal reception status, charging current setting value assigned to the mobile charging device from the mediation server 700, power billing cost, etc.

In addition, the charging status may include charging steps in real time, remaining charge amount, charging speed, and classification of charging power.

Meanwhile, 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 brokering module 400 of the mobile charger 200 will be implemented in an integrated form. You can.

According to this implementation form, since the power mediation module 400 is built into the connector 500, the risk of damage, flooding, theft, etc. of the power mediation module 400 can be reduced. In addition, a mechanical or electronic locking device to prevent theft may be built into the power brokering module 400 in the form of a connector 500.

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

On the other hand, the power brokering module 400 can be built into a power demand device such as an electric vehicle, and the internal battery 461 can also be replaced with an existing battery of the power demand device 600.

According to an embodiment of the present invention, the charging process using microcurrent as authentication power is as follows, and Figure 4 is a flowchart for explaining the process.

In step S100, 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 S110, a process is performed in which a small current is generated and supplied from the main power supply 10 through the small current limiting device 150.

In step S120, a micro-current flows and is supplied to the power brokerage module 400, and the power brokerage module 400 converts the micro-current into power for authentication and uses it.

In step S130, the power brokering module 400 performs a process of acquiring the authentication outlet 100 ID information transmitted by the authentication outlet 100.

In step S140, the power brokering module 400 transmits the ID of the authentication outlet 100 and the ID of the mobile charger 200 to the mediation server 700, and a process of requesting the operation password of the authentication outlet 100 is performed.

In step S150, the mediation server 700 transmits the operation password of the authentication outlet 100 to the power mediation module 400.

In step S160, the mediation server 700 performs a process of checking the specifications of the authentication outlet 100 and the power mediation module 400.

In step S170, the mediation server 700 sets the charging current to be supplied to the user's power demand device 600 and transmits a charging start command.

In step S180, a process of supplying charging power from the main power source 10 is performed by closing the single-phase or three-phase switch appropriate for the charging current set in the mediation server 700 in the authentication outlet 100.

In step S190, charging of the power demand device 600 begins as power supply begins.

Meanwhile, according to a special embodiment of the present invention, instead of using microcurrent as power for authentication, the power of a smart device can be used as power for authentication through the USB terminal 111.

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

In this case, the microcurrent becomes unnecessary, and therefore the microcurrent limiting device 150 may not be used. Using this, an In-Cable Control and Protection Device (ICCPD) whose main components are a plug power unit 320, a power relay, and a connector terminal 440 is used instead of the mobile charger 200 of FIG. 2. Charging is also possible. As shown in Figure 2, the authentication power of the smart device may be transmitted to the portable charger 200 through the outlet terminal 110. In this case, a USB standard portable auxiliary battery, etc. may be used instead of the smart device.

In addition, the smart device connected to the USB terminal 111 of the authentication outlet 100 connects to the Internet network on its own, runs an app related to mobile charging, provides the ID of the authentication outlet 100 to the mediation server 700, and operates. You can perform data transmission and reception procedures to obtain a password.

According to the above special embodiment, the charging process of using the power of the smart device as authentication power through the USB terminal 111 is as follows, and Figure 5 is a flow chart for explaining the process.

In step S200, the process of connecting the user's smart device, such as a smartphone or tablet PC that is connected to the Internet and can run a mobile charging device app, to the USB terminal 111 of the authentication outlet 100 is performed.

In step S210, power is supplied from the user's smart device to the authentication outlet 100 to generate power for authentication.

In step S220, when the authentication outlet 100 is driven via the authentication power supplied by the user's smart device, the smart device automatically recognizes the authentication outlet 100, and the mobile charging device app of the smart device runs. The process is carried out.

In step S230, a process of obtaining the ID of the authentication outlet 100 is performed in the mobile charging device app of the smart device.

In step S240, the app on the smart device connects to the mediation server 700, transmits the ID of the authentication outlet 100 and the ID of the mobile charger 200, sets the charging current, charging time, and charging amount, and then performs the payment process. do,

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

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

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

In step S280, 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 S290, charging of the power demand device 600 begins as power supply begins.

Meanwhile, according to another specific embodiment of the present invention, instead of using microcurrent as power for authentication, an internal battery 461 is provided inside the power brokering module, and the power of the internal battery 461 is used for authentication. It can be used as electric power.

Figure 3 is a diagram showing the internal battery 461 and the battery management unit 460 in the power brokering module, and Figure 6 is a flow chart to explain the process of using the internal battery 461 as power for authentication.

The procedure for using the internal battery 461 as authentication power is explained using 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 brokering module 400 of the mobile charger 200 to the authentication outlet 100 is performed.

In step S320, the authentication outlet 100 is driven via the authentication power of step S110, and the power brokering module 400 obtains the ID of the authentication outlet 100.

In step S330, the power brokering module 400 transmits the ID of the authentication outlet 100 and the ID of the mobile charger 200 to the brokerage server 700 through the wireless communication unit 430.

In step S340, the mediation server 700 transmits the operation password of the authentication outlet 100 to the power mediation module 400.

In step S350, the mediation server 700 performs a process of confirming the specifications of the authentication outlet 100 and the power mediation module 400.

In step S360, the mediation server 700 sets the charging current to be supplied to the user's power demand device 600 and transmits a charging start command.

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

In step S380, charging of the power demand device 600 begins as power supply begins.

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 limitations due to transmission lines, etc. In preparation for this case, it is necessary to provide information on the allowable current amount of the authentication outlet 100 by grading it.

As a specific method of providing, first, a method in which the authentication outlet (100) directly provides the allowable current amount information to the mobile charger (200) through the authentication outlet (100) ID information, and second, it corresponds to the authentication outlet (100) ID information. There is a method in which the allowable current amount information of the authentication outlet 100 is stored in the mediation server 700 and the mobile charger 200 receives the stored allowable current amount information from the mediation server 700 during the authentication process.

Meanwhile, according to another special embodiment of the present invention, a current greater than the allowable current specified according to the external dimension standards of the plug and outlet can be selectively allowed to flow according to mutual authentication between the authentication outlet 100 and the mobile charger 200. .

With the development of materials and monitoring technology, it is possible to allow large currents to flow, but the allowable current, which was limited to distinguish external features, can be set upward. In this case, by adding a temperature sensor and buzzer to the authentication outlet 100, a warning sound can be generated as the temperature rises, and it is also possible to block the power supply by operating the electronic switch.

According to one embodiment of the present invention, when the authentication procedure is performed using the microcurrent 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, because the small current limiting device 150 is used to limit the size of the small current, most electrical devices, including mobile phone chargers and electric shavers, do not receive power even when connected to the authentication outlet 100 without going through the authentication process. Can't receive it.

Specifically, when not authenticated (i.e., before going through the authentication process), the maximum value of the microcurrent 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 certification outlet 100, only a maximum of 2.2W (220V*10mA=2.2W) of power can be supplied, so before going through the certification process, 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 cannot be used at all before going through the authentication process. does not exist.

In other words, a small amount of current (10mA) is sufficient as an authentication power source to go through the authentication process, but even electrical devices with low power consumption, such as a smartphone charger, cannot realistically be used with this small amount of current. Even if electricity equivalent to the maximum value of microcurrent is used without permission throughout the month, the amount of electricity is only 220V*0.01A*24 hours*31 days=1.63kWh, which, when converted into money, is less than 200 won.

In addition, according to one embodiment of the present invention, a small current flows only when the mobile charger 200 is connected to the authentication outlet 100, and when the mobile charger 200 is disconnected from the authentication outlet 100, the power relay As the unit 130 is opened, current no longer flows from the main power source 10 to the mobile charger 200 via the outlet power unit 140 of the authentication outlet 100 and the plug power unit 320 of the mobile charger 200.

When the mobile charger 200 is not connected to the authentication outlet 100, not even a small amount of current flows. Therefore, during standby operation of the authentication outlet 100, components for user authentication do not consume power, that is, standby power. .

This prevents the problem of inconsistency between those who bear the cost of standby power (e.g., building owners, etc.) and actual users (e.g., electric vehicle owners, etc.).

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 Since power charge information can no longer be transmitted to the mediation server 700, problems related to this may occur.

To solve this problem, 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 and transmit power charge amount information per unit time to the mediation server.

If the power demand device 600, for example, an electric vehicle, is fully charged, the power charge amount can be calculated for the entire time the mobile charger 200 was connected to the authentication outlet 100 and received power.

However, in contrast to this, if the mobile charger 200 is separated from the authentication outlet 100 in the middle without fully charging the electric vehicle, the mediation server 700 is connected in the last unit time period before separation (i.e., before communication interruption). The amount of power charge transmitted can be regarded as the amount of power charge per unit time period when separation (i.e., communication interruption) occurs.

For example, when the unit time period is 1 minute, the last power charge amount was transmitted to the mediation server 700 10 minutes after charging, and if charging was stopped between 10 and 11 minutes, between 9 and 10 minutes. The power charge amount can be considered as the power charge amount between 10 and 11 minutes. This consideration is based on the fact that when charging an electric vehicle, it is charged at rated capacity up to 80 to 90% of the full charge, and then the current drops rapidly.

In contrast, the unit time period may be arbitrarily selected, such as 10 minutes, 5 minutes, or 30 seconds, rather than 1 minute. If the electric vehicle is not fully charged and is disconnected in the middle, as can be seen from the previous assumption, the larger the unit time period, the more the electric vehicle's power charge will be overestimated, and the smaller the unit time period, the less the electric vehicle's power will be charged. The amount of charge will be calculated more accurately.

Therefore, it would be ideal to transmit power charge amount information in real time, but there is a problem in terms of cost because communication costs increase significantly due to problems such as data communication volume.

Preferably, the unit time period may be 1 minute as in the previous example. In this case, if the electric vehicle electricity rate system is applied and the electric vehicle is charged at 3.3 kW per hour, the average electricity bill is 330 won per hour. Therefore, if 1 minute is the unit time period, the electricity bill for 1 minute is 5.5 won.

As described in detail above, according to the present invention, there is an effect of providing a charging system that can stably charge a plurality of power demand devices 600 while stably maintaining the power situation of the main power source 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 power demand device 600 charging system that can simplify and automate the billing process for power use related to charging of the power demand device 600.

In addition, a charging system is provided that can improve user convenience by adaptively responding to changes in the power situation of the main power source 10 and automatically performing charging interruption and resumption operations for the power demand device 600 without user intervention. There is an effect.

Meanwhile, when large power is supplied for charging the power demand device 600, heat is generated at the internal terminals of the authentication outlet 100 and the mobile charger 200, raising the risk of fire. In order to cope with this, the charging power supply section between the power relay unit 130 and the outlet power unit 140 of the authentication outlet 100, the plug power 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 temperature of the heating portion can be measured to control the charging amount (charger control unit 410, outlet control unit 120) or to stop charging.

Meanwhile, the charging-related technology used in the present invention can be equally applied to discharge such as V2G (Vehicle To Grid) depending on power demand and supply conditions. You can set the discharge current in an equivalent way to setting the charging current and supply it to your home and grid, and for the power transmitted in this reverse direction, you can receive a discharge payment from the power company, etc. according to the amount of power.

The embodiments of the present invention described above are merely illustrative, and those skilled in the art will understand that various modifications and other equivalent embodiments are possible.

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