Smart street light and street light system having electric vehicle charging function

The present invention relates to a smart street light and a street light system having an electric vehicle charging function, and more particularly, to a technology that supports charging an electric vehicle while performing the original function of a street light to illuminate a road.

Recently, environmental pollution and energy saving issues have drawn a lot of attention to eco-friendly vehicles, and among eco-friendly vehicles, electric vehicles are a representative example.

An electric vehicle is a vehicle that uses electricity to move, and it refers to a vehicle that stores electric energy in a battery and uses it as a raw material. Electric vehicles can be classified into electric vehicles (EVs), plug-in hybrid EVs (PHEVs), hybrid EVs (HEVs), and the like according to the method and rate of use of electric energy.

First, HEV is a vehicle that combines the power of two types of internal combustion engine and electric motor. PHEV refers to a vehicle designed to be used by externally charging the HEV's battery, while EV refers to a vehicle powered only by batteries and an electric motor.

HEVs, PHEVs, and EVs have in common that electric energy is used to drive the vehicle, but HEVs generate and use electric energy within the vehicle, whereas PHEVs and EVs require external power to be supplied. Therefore, in order to popularize electric vehicles, it is necessary to build a charging infrastructure that anyone can use conveniently.

However, charging stations are not yet widely distributed. The reason is that the cost of installing each electric vehicle charging station is much higher than that of existing gas stations, so profitability cannot be guaranteed.

Therefore, for the expansion and dissemination of electric vehicles, the supply of a sufficient number of charging stations is urgently required. The present inventor intends to find an answer in the street lamps that have already been installed on roads or parking lots and have sufficient power supply and demand.

Meanwhile, as a prior art related to electric vehicle charging, there is Korean Patent Publication No. 10-2011-0082120 (2011.07.18. 'electric vehicle charging station') and the like.

The present invention has been devised to solve the problems of the prior art as described above, and by enabling charging of an electric vehicle using an already installed street lamp without installing a separate electric vehicle charging station, the difficulty of securing an installation place is eliminated. The purpose is to provide a technology that can solve the problem and reduce the installation cost.

A street light system according to the present invention for achieving the above object, a smart street light to which an electric vehicle is connected; a distribution board for supplying power to the smart street light; and a charging support server that receives reservation information from a user terminal and transmits it to the distribution panel side or supports payment processing according to electric vehicle charging using the smart street light; wherein the smart street light is electrically connected to the electric vehicle Including a charging connection unit, the distribution panel, the power supply to receive power from the outside and supply to the smart street light; a street light control unit supplying or blocking the power distributed from the power supply unit to the smart street light to control the turn-off of the smart street light; and a charging control unit supplying the power distributed from the power supply unit to the electric vehicle side connected to the charging connection unit of the smart street lamp.

Here, the distribution board further includes a communication unit that transmits and receives information by connecting a communication channel with the charging support server or the user terminal, and receives reservation information through a dedicated application in the user terminal possessed by the user using the electric vehicle. When inputted and transmitted to the charging support server side, the charging control unit receives reservation information from the charging support server through the communication unit, and when it is confirmed that the user terminal has approached through the communication unit, the charging control unit of the user terminal After obtaining the information, verifying the comparison with the reservation information and performing authentication, it is possible to process so that power can be supplied through the charging connection unit of the smart street lamp.

In addition, the smart street lamp further includes a cover that protects the charging connection, and the charging control unit of the distribution panel opens the cover of the smart street lamp when authentication for the user terminal is performed to expose the charging connection. can do.

In addition, the smart street light, a parking sensor for detecting whether parking; and a notification means for outputting moving parking guidance information; further comprising, the charging control unit of the distribution panel is connected to the dedicated application of the user terminal within a predetermined time after parking is detected through the parking detection sensor of the smart street lamp, and , when it is not confirmed, it is possible to process so that the moving parking guide information is output through the notification means.

On the other hand, a smart street light according to the present invention is a smart street light that can charge an electric vehicle by receiving power from a distribution board, and the smart street light includes: a charging connection unit to which an electric vehicle is electrically connected; a parking sensor for detecting whether parking is present; and a notification means for outputting mobile parking guide information; and, when the user terminal using the electric vehicle inputs reservation information through a dedicated application and transmits it to the charging support server, the distribution board is the charging support server When it is confirmed that the user terminal has approached the distribution board by receiving the reservation information from The distribution panel checks whether it is connected to the dedicated application of the user terminal within a certain time after parking is detected through the parking detection sensor of the smart street light, and if not confirmed, mobile parking guidance information through the notification means can be processed to be output.

According to the smart street light and street light system having an electric vehicle charging function according to the present invention, the following effects can be expected.

First, the street lamp according to the present invention can provide an electric vehicle charging function while performing its original function of illuminating the road by turning on the light emitting means. Therefore, it is possible to charge electric vehicles on roads and parking lots without installing a separate electric vehicle charging port.

In other words, it is possible to replace electric vehicle charging facilities by using street lamps with a smooth supply and demand, thus solving the problem of securing space for installing a charging station or charging port and the problem of burying power lines separately.

In addition, if you want to charge an electric vehicle through the street lamp according to the present invention, it is possible to check the charging location, make a charging reservation, authenticate, and pay through a dedicated application.

In addition, since the charging connection part to which the charging connector is connected from the street lamp is normally kept covered by the cover, it is possible to eliminate reckless attempts to use power and to prevent electric shock accidents caused by children's pranks.

In addition, it is possible to automatically set a destination for a reserved street lamp through navigation linked with a dedicated application, simplifying the process of finding a charging place.

In addition, since a notification means is installed on the exterior of the street lamp body, electric vehicle users can check the location of the street lamp where electric vehicle charging is possible from a distance. may be

In addition, mobile parking is recommended for vehicles that are not parked for the purpose of charging electric vehicles or for vehicles that have been charged, so that priority can be given to vehicles requiring charging.

In particular, in the street light system according to the present invention, the components for connecting the electric vehicle and exchanging commands with the user are installed on the street lamp, and the components for charging control are installed on the distribution panel, thereby lowering the overall system construction cost and reducing the number of vehicles that can be charged at the same time. The advantage is that it can be extended to the maximum.

That is, the number of electric vehicles that can be connected to one charging facility is inevitably limited. For example, suppose that a plurality of charging connections are provided on the distribution board. In this case, unless the vehicle is parked immediately adjacent to the distribution board, the cable must be extended to a considerable distance to the location of the vehicle, even if a connector can be connected to the charging connector. Therefore, it is more efficient in terms of space utilization to provide a charging connection for a street lamp with a relatively large number of installations rather than providing a plurality of charging connections on the distribution board.

However, installing the charging control unit and memory that exchanges information with the charging support server or supports reservation processing and payment processing, and an accumulator to check the amount of charging power in each street lamp will greatly increase the system installation cost. do.

To this end, in the street light system of the present invention, the charging connection unit, key input unit, screen output unit, audio output unit, notification means and parking sensor, which are components that must directly face the user, are installed in a street lamp distributed over a relatively wide area, The configuration of the charging control unit, accumulator, and memory, which are components that support charging control and payment without having to face the user, should be provided in the distribution panel, and then one distribution panel should handle the charging control of several street lights in charge. did

Therefore, the system construction cost can be reduced to the maximum and the space utilization is very high because the maximum number of electric vehicles can be simultaneously charged through the streetlights installed in relatively large numbers in a wide area.

Hereinafter, a process of charging an electric vehicle through the street lamp system shown in FIGS. 1 and 2 will be described with reference to FIGS. 3 to 7 .

Prior to the description, in the street lamp system according to the present invention, a dedicated application (dedicated app) for using this service is installed in the user terminal 30 possessed by the electric vehicle 20 user, and a series of processes for charging through the dedicated application this will be done To this end, the user may download and install a dedicated application provided by the charging support server 60 through the user terminal 30 in advance, and in this process, a member registration or user registration may be performed.

In addition, the street lamp 10 of the street lamp system according to an embodiment of the present invention may be installed on a pedestrian path, a driveway, a public parking lot, a park parking lot, etc. This is to inform you of what should be done.

Hereinafter, it is assumed that the user visits the park parking lot and attempts to charge the electric vehicle 20 and the process will be described.

Referring to FIG. 3 , the user of the electric vehicle 20 who has the user terminal 30 installed with the dedicated application executes the dedicated application, selects a specific street lamp 10 of the parking lot of the park to visit, and then proceeds with charging reservation <S305> do. Of course, since the street lights 10 installed in the parking lot of the park are grouped in a predetermined group, the user can make a reservation only for the group (park parking lot) without designating the specific street light 10, and in this case, the street lights 10 of the group ), any one of the street lamps 10 can be freely used. Of course, information on usage time can also be entered (or selected) during the reservation process.

Information on the location and time of the street lamp 10 that can be reserved is converted into a database in the charging support server 60 and operated in real time, and the charging support server 60 and the user terminal 30 are connected through a dedicated application to make a reservation procedure After completing, the reservation information is transmitted to the distribution board 40 in charge of the corresponding street light 10, and when the reservation information is received through the communication unit 42 in the distribution board 40 in charge of the corresponding street light 10, the charging control unit ( 46 stores reservation information in the memory 55 .

After that, when the reserved time arrives, the user visits the parking lot of the park and approaches the specific street lamp 10 near <S310> and then completes the parking, the distribution panel 40 performs an authentication <S315> procedure for the user.

The authentication procedure for the reserved user may be performed in several ways. First, when a user having a dedicated application installed approaches and tries to park near the street lamp 10 , the communication unit 42 of the user terminal 30 and the distribution panel 40 may connect a Bluetooth communication channel. That is, although the user is located near the street light 10 , the distribution board 40 in charge of the corresponding street light 10 is also located nearby, so the communication unit 42 of the user terminal 30 and the distribution panel 40 also has a Bluetooth communication radius. it will be soon

Therefore, even if the user does not perform a separate procedure, when the communication unit 42 of the distribution panel 40 acquires the unique ID of the user terminal 30 in the process of connecting the Bluetooth communication channel, the charging control unit 46 stores the reservation stored in the memory 55 . After comparison with the unique ID of the user terminal 30 included in the information, authentication can be automatically processed.

Alternatively, authentication may be performed automatically through comparison of authentication information generated by a dedicated application rather than a unique ID of the user terminal 30 . That is, when the user completes the reservation procedure in the preceding process, authentication information is generated in the dedicated application and included in the reservation information, and then transmitted to the charging support server 60, and this reservation information is stored in the memory 55 of the distribution board 40. . Afterwards, when the user terminal 30 approaches the street light 10 or the distribution panel 40, the dedicated application automatically transmits the authentication information created and stored in the reservation process to the distribution panel 40 when the Bluetooth communication channel is connected, and then After the charging control unit 46 compares the authentication information received from the user terminal 30 with the authentication information of the reservation information stored in the memory 55, authentication may be processed.

After the electric vehicle 20 is parked in a dedicated parking space near the street lamp 10 in this way, when the authentication procedure for the user is completed on the distribution board 40 <S315>, the charging control unit 46 moves to the reserved street lamp 10 side. By sending a signal to drive a motor (not shown), the cover 14 that has covered the charging connection part 13 is opened <S320>. That is, the charging connection unit 13 is normally covered with the cover 14 to prevent unauthorized use of power by unauthorized users or pranks by children. This is to enable connector connection.

Thereafter, when the user connects the connector connected to the electric vehicle 20 to the charging connection unit 13 , the charging control unit 46 provides power supplied from the power supply unit 43 to the electric vehicle 20 side to charge the electric vehicle 20 < S325 > to make it happen.

When the connection state of the electric vehicle 20 is maintained for a predetermined time and charging is completed, the charging control unit 46 communicates to the communication unit 42 that charging is complete together with information on the amount of charging power calculated through the accumulator 49 . It is transmitted to the charging support server 60 through. Thereafter, the charging support server 60 calculates the cost in response to the amount of charging power, and transmits the charging completion guide information together with the payment information to the user terminal 30 to perform the payment processing <S330>.

That is, the user may receive guide information indicating that charging is complete through the push function of the dedicated application installed on the user terminal 30 , and may process payment through the payment guide information. Payment can be made through the credit card registered during the membership registration process after the installation of the dedicated application.

After that, when the user approaches the street lamp 10 again and disconnects the connector, the charging control unit 46 checks the disconnection of the connector and transmits a signal to the street lamp 10 so that the cover 14 is closed again to close the cover ( 14) through the charging connection unit 13 can be protected.

Meanwhile, in the process of FIG. 3 , the process of making a reservation for use of the street lamp 10 at a specific location first and then charging and payment has been described. may be

That is, if a user who has installed a dedicated application but has not taken a separate reservation procedure runs the dedicated application after parking near the streetlight 10, in the dedicated application, the distribution board 40 at a location where Bluetooth connection is currently possible and the streetlight 10 connected thereto ) is automatically output, and after the use request and authentication process are performed on the fly, the cover 14 of the street lamp 10 for which the use request is made is opened, the connector is connected, and charging is carried out will do

In addition, the user of the electric vehicle 20 who has not installed the dedicated application inputs the use request information through the key input unit 15 installed outside the street light body 10a of the street lamp 10, and through the card recognition unit (not shown) By processing the payment, the electric vehicle 20 can be charged.

Also, if the payment processing is described in more detail, the payment method may be selectively performed among a post-payment method and a pre-payment method. That is, if you have previously registered your credit or debit card or simple payment information through a dedicated application, you may support deferred payment because the validated payment method is registered. In this case, after making a reservation for charging or making a request for charging through a dedicated application at the site, after charging is completed, payment is made in a deferred payment in proportion to the amount of power used calculated by the accumulator 49 .

However, there may be cases where a payment method validated through a dedicated application is not registered, or even a user through a dedicated application wants to pay using a real card on the spot. In this case, it is preferable that the prepayment is made because there is a risk that the payment process may not be smooth when the post-payment is attempted after the charging is first made.

For example, if the charging amount is input through the key input unit 15 of the street lamp 10 or the charging amount (electricity) is input, a prepayment is requested for the corresponding cost, and a separate card reader (not shown) After recognizing the card, if the normal approval is approved, the prepayment is processed, and then the cover 14 is opened, and then the connector is connected to the charging connection part 13 to perform charging.

If the user entered the charging amount or target charging amount and made a prepayment, the user inevitably had to stop charging and move the vehicle, or if the battery was fully charged and charging was stopped even though the charging amount or the target charging amount was not fully charged, The charging control unit 46 notifies the charging support server 60 of the fact that the charging has been stopped without meeting the target, and transmits information on the amount of charging made so far through the accumulator 49, so that the charging support server 60 is The existing payment can be canceled and the repayment can be processed only by the amount of charging actually made.

4 is a flowchart for explaining a function of supporting a user who has made a reservation through a dedicated application provided by the street light system according to the present invention to smoothly come to the reserved street light (or park).

That is, in the process of Figure 3, after the user performs a reservation procedure for a specific street lamp 10 or a specific park parking lot through a dedicated application <S305>, the reserved street lamp 10 (or in the dedicated application of the user terminal 30) Coordinate information (location information) for the park parking lot) is generated <S405>.

After that, the dedicated application delivers the coordinate information of the street lamp 10 created to the navigation app linked in advance <S410>, and the navigation app displays the reserved location of the street lamp 10 based on the received coordinate information and automatically returns to the destination. Set <S415>.

Therefore, the user can automatically receive a navigation service for visiting a corresponding location even if the user only completes the reservation for the use of the street lamp 10 in the dedicated application used for the electric vehicle 20 charging service.

5 is a flowchart illustrating a process of displaying whether an electric vehicle can be charged in a street lamp system according to an embodiment of the present invention.

That is, when a user who has made a reservation for use of a specific street lamp 10 through the process of FIG. 3 approaches the location of the corresponding street lamp 10, the unique ID obtained through the Bluetooth connection from the charging control unit 46 of the distribution panel 40 It is possible to confirm <S505> that the reserved user has approached the street lamp 10 through comparison and confirmation of The charging support server 60 transmits a push notification to the user terminal 30 of the reservation <S510>, so that the user can recognize that it is located near the reserved street light 10.

At the same time, the charging control unit 46 of the distribution board 40 controls the notification means 18 of the street lamp 10, so that the user can see that the street lamp 10 seen through the notification means 18 is the reserved street lamp 10. can be visually guided to <S515>. For example, the charging control unit 46 may notify the location by flashing a green light through the notification means 18 .

Therefore, after the user approaches the reserved street light 10 location, the user does not need to check the exact location and get lost through push notification of the user terminal 30 and the notification means 18 of the street light 10 blinking to determine the exact location After checking, you can park in the correct position.

Of course, the charging control unit 46 always turns on the green light through the notification means 18 of the street lamp 10, regardless of the reservation user's approach, and the specific electric vehicle 20 is connected to be charged. In this case, the red light is turned on so that it is possible to determine whether it is being used from a distance.

In addition, the charging control unit 46 of the distribution board 40 is already charging other electric vehicles 20 in all the street lamps 10 in charge, and when it is confirmed that the reserved user has accessed in this state, the charging support server 60 ), but notifies that it is currently unavailable, and the charging support server 60 responds in response to charging using a nearby street lamp 10 through a push notification to the user terminal 30 of the reserved user. It is possible to guide information indicating that it is impossible and the location of the available street lamp 10 located in the nearest position.

6 is a flowchart for explaining a process of giving priority to an electric vehicle user with respect to a parking space near a street light in the street light system according to an embodiment of the present invention.

That is, the charging control unit 46 of the distribution board 40 monitors in real time whether a specific vehicle is parked in a parking space where the electric vehicle 20 can be charged through the parking sensor 19 installed in the street lamp 10 . If it is detected through the parking sensor 19 that a specific vehicle has entered the corresponding parking space and has been parked <S605>, the charging control unit 46 of the distribution board 40 is installed in the user terminal 30 with a dedicated application within a certain period of time. ) and check <S610>. At this time, the charging control unit 46 does not check whether the user terminal 30 of the reserved user is connected, but checks whether the user terminal 30 in which a dedicated application for the electric vehicle 20 charging service is installed is connected. This is because, even if it is not a reserved user, if a user with a dedicated application is installed, it is highly likely that the vehicle is parked in the corresponding space for charging the electric vehicle 20 .

If it is confirmed that the charging control unit 46 is connected to the user terminal 30 in which the dedicated application is installed even if it is not a reserved user or a reserved user as a result of checking <S615>, the user is authenticated and the electric vehicle 20 is charged The subsequent process of FIG. 3 is performed.

On the other hand, if it is not connected to the user terminal 30 in which the dedicated application is installed within a certain period of time after it is confirmed that the parking has been made through the parking sensor 19, the charging control unit 46 is configured with the notification means 18 of the street lamp 10 and Guide information recommending moving parking is output through the voice output unit 17 <S620>.

Of course, the dedicated application is not used, but it may be a vehicle parked to try to charge the electric vehicle 20 in the field through the key input unit 15 . Therefore, the charging control unit 46 uses the notification means 18 of the street lamp 10 and the voice output unit 17 to provide a key input unit according to the guidance because the corresponding parking position is a space for charging the electric vehicle prior to the guidance information recommending moving parking. It is desirable to inform the user that the charging service can be used through (15) first, and if not, it is desirable to inform that mobile parking is recommended.

For example, the charging control unit 46 of the distribution board 40 guides moving parking if the dedicated application connection is not confirmed within 30 seconds to 90 seconds after parking is confirmed through the parking sensor 19 of the street lamp 10 . 30 to 90 seconds are the average time it takes to get out of a certain distance after parking and getting off. That is, if it is confirmed in the charging control unit 46 that the connection of the dedicated application is not confirmed and the authentication procedure through the key input unit 15 is not performed within 30 to 90 seconds after parking, the vehicle is not the electric vehicle 20 or Even if the electric vehicle 20 is not visited for the purpose of charging, the electric vehicle 20 that needs charging can preferentially park by recommending mobile parking through the notification means 18 and the voice output unit 17. is to make it

Meanwhile, in the previous description, after normal authentication is completed, the connector of the electric vehicle 20 is connected to the charging connection part 13 of the street lamp 10 and when charging is completed, it has been explained that the user terminal 30 is informed of the completion of charging. In this case, the charging support server 60 recommends moving parking when notifying the user terminal 30 of the completion of charging, and may also provide guidance information that additional parking fees may be collected if the mobile parking is not performed within a certain period of time.

That is, according to the process of FIG. 6 , in the parking space near the street lamp 10 according to the embodiment of the present invention, mobile parking is recommended for other vehicles so that the vehicle for charging the electric vehicle 20 can park preferentially. That is, the privilege of giving priority to parking to a vehicle requiring charging of the electric vehicle 20 is granted. However, if the charging is completed through a due process, the priority for the parking space must be transferred to other charging vehicles. Here, when several streetlights 10 are grouped together in a certain group, the charging support server 60 determines the usage status of each streetlight 10 or the parking spaces detected by the parking sensor 19 of each streetlight 10 . By understanding the parking status, a push notification is sent to recommend moving parking after charging is completed only when all the streetlights 10 in the group are in use, and the available streetlights 10 among the streetlights 10 in the group remain Or, if it is confirmed that there is enough parking space for charging an electric vehicle, it can be operated flexibly so that a push notification is not sent even when charging is complete.

7 is a flowchart for explaining a process of preserving the use of a nearby parking vehicle requiring electric vehicle charging in the street lamp system according to an embodiment of the present invention.

That is, if the vehicle that has passed through the process of FIG. 3 has undergone a proper procedure for a specific street lamp 10 is charging the connector by connecting the connector <S325>, the charging control unit 46 of the distribution board 40 is the street lamp 10 By turning on the red light through the notification means 18 of the current street lamp 10, it is possible to know from a distance that other vehicles are being charged. At the same time, the charging control unit 46 also displays the charging progress (remaining time or percentage) of the vehicle currently charging through the notification means 18 .

The reason for displaying the charging progress is whether to move to another street light (10) location after checking the charging progress in the vehicle that approached late, even if another vehicle is currently charging, or to wait for a while and then try charging your own vehicle. This is for reference so that you can make a decision.

If another user who has confirmed that the remaining charging time of the vehicle currently being charged is not much left through the charging progress rate output to the notification means 18, parks near the street lamp 10, takes charge of the street lamp 10 In the charging control unit 46 of the distribution board 40, the connection with the dedicated application installed in the user terminal 30 of the other user who has been approached late will be confirmed <S710>. In this way, when the connection to the dedicated application installed in the user terminal 30 of another user is confirmed in the distribution panel 40 in charge of the street lamp 10 currently charging is in progress, the charging control unit 46 is configured to the corresponding user terminal 30 through the communication unit 42. ) to (or to the user terminal 30 side through the charging support server 60) and transmits a push and pop-up notification. The push and pop-up notification is guide information <S715> asking whether to reserve a priority for use of this street lamp 10 .

If the other user rejects or ignores the reservation for the first use <S720>, the charging control unit 46 of the distribution board 40 does not proceed with the additional procedure.

On the other hand, if the other user selects the reservation for preferential use of the street lamp 10 through the pop-up window of the dedicated application <S720>, the charging control unit 46 is the other user who has reserved the preferential use for a certain period of time after the current vehicle is fully charged. Priority is given to <S725>.

For example, if vehicle A is charging and vehicle B is parked nearby and reserved for priority use through a pop-up, the street lamp 10 gives priority to vehicle B for 30 minutes after charging of vehicle A is completed. . Therefore, even if a new vehicle C intervenes before the owner of vehicle B approaches again to connect the connector after the charging of vehicle A is completed, the connector connection and charging of vehicle B, which has priority, is made possible.

Meanwhile, FIG. 8 is a view for explaining an example in which a distribution board and a street lamp of a street light system according to an embodiment of the present invention are installed in a parking lot. As shown in FIG. 8, street lamps 10 are installed at regular intervals on sidewalks or flower beds around the parking space in the parking lot, and for supplying power to a predetermined number of street lamps 10 and controlling the lighting A distribution board 40 is installed. Accordingly, the electric vehicle 20 parked near the street lamp 10 may be charged in the parking state after completing a predetermined authentication procedure and then connecting the connector to the charging connection unit 13 exposed outside the street light body 10a. .

As described in detail above, according to the smart street light and the street light system according to the present invention, the following effects can be expected.

First, the street lamp 10 according to the present invention can provide a function of charging the electric vehicle 20 while performing its original function of illuminating the road by turning on the light emitting means. Therefore, even if the electric vehicle 20 charging port is not separately installed, it is possible to charge the electric vehicle 20 in various places on the road and in the parking lot.

In other words, since the electric vehicle 20 charging facility can be replaced by using the street lamp 10, which has a smooth power supply and demand, it is possible to simultaneously solve the problem of securing space for installing a charging station or charging port and the problem of burying the power line separately. .

In addition, if you want to charge the electric vehicle 20 through the street lamp 10 of the street lamp system according to the present invention, it is possible to check the charging location, make a charging reservation, authenticate, and pay through a dedicated application.

In addition, since the charging connector 13 to which the charging connector is connected in the street lamp 10 is normally kept hidden through the cover 14, reckless attempts to use power can be eliminated, and electric shock accidents caused by children's pranks can be prevented. there is.

In addition, it is possible to automatically set a destination for the reserved street lamp 10 through a navigation linked with a dedicated application, thereby simplifying the process of finding a charging place.

In addition, a notification means 18 is installed on the exterior of the street lamp body 10a of the street lamp 10, so that the user of the electric vehicle 20 can check the location of the street lamp 10 where the electric vehicle 20 can be charged from a distance, and the charging progress rate After confirming, you can also reserve priority use after parking near a vehicle that is almost fully charged.

In addition, when the electric vehicle 20 is not parked for the purpose of charging, or by recommending mobile parking for a vehicle that has been fully charged, priority can be given to a vehicle requiring charging.

In particular, in the street light system according to the present invention, the components for connecting the electric vehicle 20 and exchanging commands with the user are installed in the street light 10, and the components for charging control are installed in the distribution panel 40, so that the total system construction cost is reduced. It has the advantage of being able to lower it and increase the number of vehicles that can be charged at the same time to the maximum.

That is, the number of electric vehicles 20 that can be connected to one charging facility is inevitably limited. For example, suppose that a plurality of charging connection parts 13 are provided on the distribution board 40 . In this case, unless the vehicle is parked immediately adjacent to the distribution board 40 , even if the connector can be connected to the charging connection unit 13 , the cable must be extended to a considerable distance to the location of the vehicle. Therefore, it is more efficient in terms of space utilization to provide the charging connection unit 13 in the street lamp 10 having a relatively large number of installations rather than providing a plurality of charging connection units 13 on the distribution board 40 .

However, each street lamp includes a charging control unit 46 and memory 55 that exchange information with the charging support server 60 or support reservation processing and payment processing, and an accumulator 49 for checking the amount of charging power. The installation in (10) greatly increases the system installation cost.

To this end, in the street light system of the present invention, the charging connection unit 13, the key input unit 15, the screen output unit 16, the voice output unit 17, the notification means 18, and the parking detection are components that must be directly faced with the user. The sensor 19 is installed in the street lamp 10 distributed over a relatively wide area, and the charging control unit 46, the accumulator 49, After the configuration of the memory 55 and the like is provided in the distribution board 40 , one distribution board 40 handles the charging control of several street lamps 10 in one batch.

Therefore, the construction cost of the system can be reduced to the maximum, and the maximum number of electric vehicles 20 can be simultaneously charged through the street lamps 10 installed in relatively large numbers in a wide area, so the space utilization is very high.

The above-described preferred embodiments of the present invention have been disclosed for the purpose of illustration, and those skilled in the art with common knowledge about the present invention will be able to make various modifications, changes and additions within the spirit and scope of the present invention, such modifications, changes and additions should be considered to fall within the scope of the claims of the present invention.
