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

Figure 1 is a diagram showing an electric vehicle charging control system according to an embodiment of the present invention, and Figures 2 and 3 are diagrams showing the system of Figure 1 schematically.

1 to 3, the electric vehicle charging control system 90 according to an embodiment of the present invention includes an electric vehicle charging device 100, a user terminal device 110, a communication network 120, and a charging control device 130. ) and some or all of the third-party device 140.

Here, “including part or all” means that the electric vehicle charging control system 90 is configured by omitting some components such as the third-party device 140, or some of the components constituting the charging control device 130. Or, it means that the entire device can be integrated and configured into a network device (e.g., wireless switching device, etc.) constituting the communication network 120, and is explained as including everything to facilitate a sufficient understanding of the invention.

As can be seen in FIGS. 2 and 3, the electric vehicle charging device 100 according to an embodiment of the present invention includes a stopper-type electric charger 101, a distribution box (or power distributor) 102, a wireless communication device 103, Includes part or all of the kiosk terminal device 104, where "including part or all" means that some components, such as the wireless communication device 103, are installed in the kiosk terminal device 104 or the distribution box 102. It means something that can be integrated and composed.

The stopper-type electric charger 101 is, for example, an electric vehicle charger, and is installed in a stopper in a place such as a parking lot of an apartment complex or apartment. A stopper is a structure that prevents a vehicle from leaving the parking area by braking its movement when reversing. Of course, the stopper-type electric charger 101 according to an embodiment of the present invention can be installed inside a stopper made of an existing material such as rubber, but the stopper itself is formed or configured as a single stopper-type electric charger 101. Since any number of configurations are possible, embodiments of the present invention will not be specifically limited to any one form.

Above all, the stopper-type electric charger 101 according to an embodiment of the present invention may be configured with different types of connectors or outlets built-in. In other words, electric vehicle charging cables can be configured to different specifications depending on the manufacturer. This may also be the reason why standardization has not yet progressed. Representatively, it appears that Type B and Type C are currently being distributed on the market, and therefore, the stopper-type electric charger 101 may include multiple types of connectors so that Type B or C, as well as other types of cables, can be connected. You can. This makes it possible to charge all types of electric vehicles. The stopper-type electric charger 101 according to an embodiment of the present invention may be configured with an AC 220V, 60Hz single-phase, two-wire connector.

Of course, the stopper-type electric charger 101 can form a main body that constitutes a connector or an external frame in the form of an outlet, and a circuit part can be formed inside the main body or through a separate device. Here, the circuit unit can be viewed as a driving device for selectively controlling power or voltage supplied to the electric vehicle through a connector by configuring a CPU, etc. on a PCB board. The corresponding driving device can communicate with the kiosk terminal device 104, etc.

In addition, the stopper-type electric charger 101 is capable of smart power distribution according to the number of electric vehicles charged, and can enable wired and 1:N wireless communication. For this purpose, in the case of a wired method, a distribution box 102, that is, a power distributor, can be provided, and the power distributor can be controlled by the kiosk terminal device 104. For example, stopper-type electric chargers 101 each installed in a plurality of stoppers may operate in parallel connection with each other based on a voltage supply source. Each stopper can be controlled by switching through a distributor or the like. Therefore, if there is a request for charging from vehicle 1, power is supplied to line 1, and in the process, if there is a request for charging from vehicle 2, the power supply circuit is also operated through the line of vehicle 2. It can be driven in parallel by a distributor, etc. This is a stopper-type electric charger (101) capable of smart charging that does not exceed the contracted power when simultaneously charging at maximum, and can be blocked in the event of overvoltage or overcurrent. It can be determined by measuring the sensed value through voltage or current sensing. A dedicated outlet for charging chargers of 3 to 50 KW can be built in. With a central kiosk control method, it can operate as an electric vehicle charger using an RF reader, credit card, QR payment, and a screen that can determine parking location.

Meanwhile, the stopper-type electric charger 101 according to an embodiment of the present invention may be configured to include the user's user terminal device 110 and a short-range wireless communication, such as an NFC tag or a short-range communication module for NFC. In the embodiment of the present invention, an NFC tag is used for convenience of explanation, but various methods can be used for short-distance wireless communication between the stopper-type electric charger 101 and the user terminal device 110. For example, a device for beacon communication may be used. However, considering power consumption and installation costs, a method using an NFC tag may be preferable. As shown in FIGS. 2 and 3, the user of the user terminal device 110 may use the kiosk terminal device 104 when the kiosk terminal device 104 is outside a designated distance from the stopper-type electric charger 101, for example, from the user's location. If the vehicle is far away or inconvenient to access, you can easily charge the electric vehicle using NFC tagging using an application (hereinafter referred to as the app). Based on this, NFC tagging can be performed only on the stopper-type electric charger 101 that is outside the designated distance from the kiosk terminal device 104, rather than NFC tagging when executing the app. For example, when the app is executed on the user terminal device 110, if it is determined that the stopper-type electric charger 101 and the kiosk terminal device 104 are within a specified distance, the surrounding kiosk terminal device is sent through a push message from the app. Notification may be made to use (104). Of course, this notification may be transmitted from the charging control device 130 of FIG. 1. Of course, in the embodiment of the present invention, not only the distance between the user's current location and the kiosk terminal device 104, but also the user terminal device ( 110) may be allowed to be used for charging.

As can be seen in FIG. 3, the distribution box 102 may include a main breaker, a control board, a channel breaker, a magnetic relay, etc. The distribution box 102 can distribute external commercial power, etc. into multiple voltages. The main circuit breaker may block power supply to a plurality of stopper-type electric chargers 101. Additionally, the channel breaker may block the power supply to each stopper-type electric charger 101. In other words, the distribution box 102 is in charge of charging the first to sixth stopper-type electric chargers 101, and at this time, when an abnormality is detected in the first electric charger 101, only the breaker of the corresponding channel is blocked to charge the remaining second electric chargers 101. The to sixth electric chargers 101 are designed to be used. The control board refers to a circuit board such as a main PCB that includes a processor such as a CPU or MPU. The control board controls a magnetic relay that operates as a switching element through communication of the kiosk terminal device 104 to connect a specific charging board, or stopper. Power can be supplied to the type electric charger 101 to charge the user's electric vehicle. For example, the control board receives the identification information of the charging board that the user wants to charge from the kiosk terminal device 104 and controls the relay connected to the charging board based on this information to allow charging to proceed.

The wireless communication device 103 may serve as an intermediary for communication between the stopper-type electric charger 101, the branch box 102, and the kiosk terminal device 104. For example, when a user of an electric vehicle wants to perform a charging operation through a kiosk terminal device 104 installed in a parking lot of an apartment, etc., the input information entered by the user is distributed in the corresponding kiosk terminal device 104 ( 102) can be transmitted to the control board. Accordingly, the charging amount, charging time, identification information of the stopper-type electric charger 101, etc. can be transmitted. Of course, the wireless communication device 103 can also transmit the relevant information to the charging control device 130 of FIG. 1 to enable charging control. In addition, when payment is made through the kiosk terminal device 104, the wireless communication device 103 transmits payment information to the third-party device 140 of FIG. 1 to request payment processing, or the charging control device 130 After payment is made, payment authentication information may be transmitted to the kiosk 104. The wireless communication device 103 may participate in this operation as a gateway.

The kiosk terminal device 104 may incur a large cost in constructing the electric vehicle charging control system 90 of FIG. 1 according to an embodiment of the present invention. Therefore, in order to save costs, one kiosk terminal device 104 is installed in an arbitrary space, such as a parking lot, but a user who charges an electric vehicle is too far away from the stopper-type electric charger 101. For this purpose, charging can be performed by NFC tagging using the user terminal device 110 carried by the user. Therefore, users do not directly perform operations for charging electric vehicles on the kiosk terminal device 104, but are provided with information related to electric vehicle charging operations performed through the app on the user terminal device 110 and use the stopper-type electric charger 101. By displaying the status on the screen, it is possible to control other users from repeatedly using the stopper-type electric charger 101.

The user terminal device 110 includes a user's terminal device that performs a charging operation of the electric vehicle owned by the user. Of course, the user terminal device 110 may include not only a mobile-based terminal device such as a smartphone, but also a PC-based terminal device that can perform operations such as reserving charging at a specific time. PC-based terminal devices may include desktop computers or laptop computers. Mobile-based terminal devices may include wearable devices that users wear on their wrists, etc., in addition to smartphones. When the user of the user terminal device 110 wants to perform a charging operation for an electric vehicle and is outside the designated distance from the kiosk terminal device 104, the user of the user terminal device 110 runs the app and tags the stopper-type electric charger 101. You can proceed with the charging process by tagging. For example, in an embodiment of the present invention, it may be possible to specify various tagging ranges for the user terminal device 110 and the kiosk terminal device 104.

In the case of the user terminal device 110, the membership registration process may be available immediately after registration through a smartphone app without a membership card. User authentication and payment are performed using a smartphone app (e.g. iPhone, Android), and payment cards can be registered in the process. Customer expansion and user convenience can be increased by maximizing service accessibility and convenience for customers without a card. Additionally, the user of the user terminal device 110 may perform operations such as parking, selecting a charger, authenticating a smartphone or membership card, and charging/paying during the charging process. Accordingly, a membership card may not be necessary, and Ministry of Environment/affiliate cards can also be supported.

For example, a typical case is that many people are standing in line at the kiosk terminal device 104. In this way, the tagging operation of the user terminal device 110 may be selectively operated depending on the situation of the kiosk terminal device 104. If the distance between the stopper-type electric charger 101 or the user terminal device 110 and the kiosk terminal device 104 is within a specified range, a notification to use the kiosk terminal device 104 may be made. Of course, even in this case, if it is determined that there is a long waiting line at the kiosk terminal device 104, NFC tagging may be temporarily possible even if it is within the designated range. In this operation, when the surrounding situation is detected through the camera of the kiosk terminal device 104, etc., the user terminal device 110 can be controlled to temporarily perform an NFC tagging operation in the charging control device 130, etc. based on this.

The communication network 120 includes both wired and wireless communication networks. For example, a wired or wireless Internet network may be used or linked as the communication network 120. Here, the wired network includes Internet networks such as cable networks and public switched telephone networks (PSTN), and the wireless communication network includes CDMA, WCDMA, GSM, EPC (Evolved Packet Core), LTE (Long Term Evolution), and Wibro networks. It means including. Of course, the communication network 120 according to an embodiment of the present invention is not limited to this, and can be used as an access network for a next-generation mobile communication system to be implemented in the future, for example, a cloud computing network in a cloud computing environment, a 5G network, etc. For example, if the communication network 120 is a wired communication network, the access point within the communication network can connect to the telephone company's exchange office, etc., but in the case of a wireless communication network, data is processed by connecting to the SGSN or GGSN (Gateway GPRS Support Node) operated by the communication company, or Data can be processed by connecting to various repeaters such as BTS (Base Transceiver Station), NodeB, and e-NodeB.

Communication network 120 may also include an access point. Access points include small base stations such as femto or pico base stations that are often installed in buildings. Here, femto or pico base stations are classified according to the maximum number of electric vehicle charging terminal devices 100 or user terminal devices 110 that can be connected in the classification of small base stations. Of course, the access point may include a short-distance communication module for performing short-distance communication such as Zigbee and Wi-Fi with the electric vehicle charging terminal device 100 or the user terminal device 110. Access points can use TCP/IP or RTSP (Real-Time Streaming Protocol) for wireless communication. Here, in addition to Wi-Fi, short-range communication can be performed using various standards such as Bluetooth, Zigbee, infrared (IrDA), RF (Radio Frequency) such as UHF (Ultra High Frequency) and VHF (Very High Frequency), and ultra-wideband communication (UWB). You can. Accordingly, the access point extracts the location of the data packet, specifies the best communication path for the extracted location, and forwards the data packet along the designated communication path to the next device, such as the charging control device 130 or a third-party device 140. It can be passed on. Access points can share multiple lines in a typical network environment and include, for example, routers, repeaters, and repeaters.

The charging control device 130 supports customer convenience through an electric vehicle charging service app or web and interfaces with external sources such as payment and authentication, such as payment servers. In addition, the charging control device 130 can collect, analyze, and store control data using a charger, kiosk, and wired/wireless communication to provide information in real time to managers, branch managers, and AS maintenance personnel.
