Description

ELECTRIC VEHICLE CHARGING APPARATUS

The present invention relates to an electric vehicle charging apparatus, which is capable of dynamically configuring a variety of charging type connectors using one base connector without having to individually provide connectors of various charging types of electric vehicles, And more particularly, to an electric vehicle charging apparatus capable of efficiently charging an electric vehicle with a corresponding charging power source.

An automobile is a moving means by which an internal engine is driven by fuel combustion. Conventional automobiles are generally movable by driving an automobile engine by burning fossil fuels such as gasoline or light oil.

Fossil fuels have limitations in remaining reserves and furthermore cause air pollution by exhaust gases emitted through combustion. In order to reduce dependence on fossil fuels and to reduce air pollution caused by the combustion of fossil fuels, vehicles using various alternative fuel resources are being developed and distributed.

Among them, automobiles using electricity as driving fuel are known as the most representative alternative fuel. An electric vehicle has a large-capacity battery inside and is movable by driving an automobile engine using a power source from a battery.

The electric vehicle has no exhaust gas and the noise is small, so it can reduce the air pollution caused by the smoke compared to the vehicle using the conventional fossil fuel, and can provide a comfortable indoor environment.

Electric vehicles are produced and supplied by various automobile companies, and electric vehicle charging devices for charging batteries in electric vehicles are needed. The electric vehicle charging apparatus is installed at a position where the vehicle can be moved, and can be generally installed in a parking lot, a gas station, a resting place or the like. The electric vehicle charging apparatus has a connector for supplying electricity, and is connected to an inlet of the electric vehicle and supplies charging power to the inlet.

On the other hand, the specifications of the connector and the inlet of each automobile company (model) are different from each other, and the electric vehicle charging device is configured to be able to charge the battery of a specific electric vehicle by individually providing connectors for each electric vehicle company or each electric vehicle model . For example, when three types of connectors are available, the electric vehicle charging apparatus has three connectors, each of which outputs charging power for each connector.

As such, the electric vehicle charging apparatus is provided with an individual cable connector according to a known known connector type and is capable of outputting the charging power to the inlet of the electric vehicle through the cable connector.

Conventional electric vehicle charging apparatuses may cause various problems. For example, when a new standard electric vehicle inlet and connector is started to be used, there is a problem that the electric vehicle charging device is required to have a new cable connector so that development cost and production cost are wasted.

In addition, each of the existing electric vehicle charging devices can charge only one electric vehicle at a time (one charge), and if the various cable connectors are provided, the cost efficiency and management efficiency of the electric vehicle charging device become poor.

In addition, each of the existing electric vehicle charging apparatuses needs to individually provide the necessary number of cable connectors, thereby consuming unnecessary power.

Thus, there is a need for an electric vehicle charging device capable of solving the problems of a known electric vehicle charging device.

First, the control server 205 of the management server 200 establishes a communication channel connection with the at least one electric vehicle charging apparatus 100 to be managed (see (1)) through a broadband communication network. For example, the control server (control unit 205) of the management server 200 registers charging device identification information (e.g., an IP address, an Internet telephone number, a telephone number) of each charging device management item in the charging device management DB of the storage unit 203 Number and / or a mobile phone number) of the electric vehicle charging apparatus 100 through the communication unit 201. [0050]

The control server 205 of the management server 200 registers the electric vehicle 400 to be charged by using the portable terminal 300 or other terminal used by the user of the electric vehicle 400 ).

In the registration process of the electric vehicle 400, the control server (control unit 205) of the management server 200 creates a new vehicle management item in the vehicle charge management DB or updates an existing vehicle management item. The control server (control unit 205) of the management server 200 may record electric vehicle identification information, user identification information, vehicle status information, card information, and the like in the vehicle management item according to the user's input or the like.

The electric vehicle identification information may include a car ID (identifier) for distinguishing from other electric vehicles 400, and the car ID may be a car number, a car number, and a string assigned in the management server 200. The vehicle ID can be input by the user through the portable terminal 300 or the like and can be authenticated in connection with an external server or the like. As the vehicle management item is registered, the charging history or state of the electric vehicle 400 can be managed.

Thereafter, the control server (control unit 205) of the management server 200 receives the charging device state information from each electric vehicle charging device 100 through the communication unit 201 connected to the broadband communication network (see (3)). The charging device status information may include location data indicating, for example, the currently installed location of the electric vehicle charging device 100. [ The charging device status information may be periodically received from each electric vehicle charging apparatus 100 or received upon change of status (change of position).

Each electric vehicle charging apparatus 100 includes a GPS sensor and senses position data such as latitude and longitude to periodically measure position data, such as sensed latitude and longitude, in accordance with a set cycle, When the difference between the position data and the threshold value is greater than a predetermined threshold value, the data can be transmitted to the management server 200 through the broadband communication network.

The control server 205 of the management server 200 searches the charging device management DB for the charging device management items corresponding to the electric vehicle charging device 100 that has transmitted the charging device status information upon receipt of the charging device status information The charging device location information of the searched charging device management item may be updated to include the received location data and the location recognition time may be updated to the time included in the received time or the charging device status information.

With this configuration, the management server 200 (the control unit 205 of) can dynamically manage the installation position of each electric vehicle charging apparatus 100 being managed.

Meanwhile, the portable terminal 300 may transmit a search request for searching the location of the electric vehicle charging apparatus 100 to the management server 200 (see (4)) through the broadband communication network. The search request may include current position data of the portable terminal 300 and search radius information (e.g., 1Km, 5Km, 10Km, etc.).

Upon receipt of the search request, the management server 200 (the control unit 205 of the management server 200) searches the one or more electric vehicle charging apparatuses 100 corresponding to the search request using the search data and the search radius information . For example, the control server (control unit 205) of the management server 200 searches the charging device location information of the corresponding charging device management item by the electric vehicle charging device 100 located within the search radius, .

The control server 205 of the management server 200 constructs a search response corresponding to the search request and transmits the search response to the broadband communication network through the communication unit 201 and receives the search request can do. The search response includes at least one identification information (charging device ID) and location information (location data) of the electric vehicle charging device 100 located within the radius centering on the search location, and further, all charging type information lists.

The portable terminal 300 can display each of the identification information and the location information of the search response on the map image. Accordingly, the user of the portable terminal 300 can charge the electric vehicle 400 in the specific charging apparatus 100 within a close distance.

On the other hand, the electric vehicle charging apparatus 100 installed at a specific position receives the payment input (refer to (6)) for charging the electric vehicle 400. For example, the electric vehicle charging apparatus 100 can receive card information or receive or recognize a user ID. According to the recognition of the card information, the electric vehicle charging apparatus 100 may perform the card preauthorization in cooperation with the management server 200 or the external server.

Further, the electric vehicle charging apparatus 100 recognizes the charged vehicle (refer to (vii)). For example, the electric vehicle charging apparatus 100 can recognize the vehicle ID through the inlet of the electric vehicle 400. [ If the vehicle ID is not recognized, the electric vehicle charging apparatus 100 may record the vehicle ID to be registered or registered in the electric vehicle 400 in advance.

For example, when the car ID is not recognized, the electric vehicle charging apparatus 100 transmits a car ID transmission request including a user ID recognized according to a user's input or the like to the management server 200, Searches the vehicle charge management DB for the vehicle management item corresponding to the user ID. In this process, the management server 200 can authenticate the user. The management server 200 may extract the vehicle ID of the searched vehicle management item and transmit a response to the transmission request including the extracted vehicle ID to the electric vehicle charging apparatus 100. [ Thereafter, the electric vehicle charging apparatus 100 records the received vehicle ID in the electric vehicle 400 so that the charging history matching the electric vehicle 400 can be managed.

Alternatively, when the vehicle ID is not recognized, the electric vehicle charging apparatus 100 transmits a registration request for registering a new vehicle management item to the management server 200 according to a user input or the like, and the management server 200 transmits the registration request The new vehicle management item is registered in the vehicle charge management DB. In the registration process, the management server 200 may generate the vehicle ID and transmit it to the electric vehicle charging apparatus 100 in response to the registration request. Thereafter, the electric vehicle charging apparatus 100 records the received vehicle ID in the electric vehicle 400 so that the charging history matching the electric vehicle 400 can be managed.

Here, the relationship between the payment inputting process and the charging vehicle recognizing process may be changed.

Then, the electric vehicle charging apparatus 100 transmits a payment request to the management server 200 (refer to (8)). For example, the electric vehicle charging apparatus 100 may be configured to determine a charging type (card, cash, transfer, etc.) determined according to user input, information (e.g., card information, account number, (Payment amount), and charging vehicle information including the recognized car ID, and transmits the payment request to the management server 200 through the broadband communication network.

The control unit 205 of the management server 200 can determine whether to authenticate and approve the payment request by interlocking with the external server (credit card server) using the payment type of the payment request and information according to the payment type. The control unit 205 of the management server 200 transmits a payment response to the electric vehicle charging apparatus 100 (refer to (9)) by constructing a response indicating payment approval or payment rejection according to the payment request. According to a design variant, the payment request may be directly transmitted to the external server (payment server) by the electric vehicle charging apparatus 100 and may receive a response therefrom.

When the settlement based on the settlement response is approved, the electric vehicle charging apparatus 100 charges the electric vehicle 400 connected through the provided connector with a charge amount corresponding to the set charge amount (refer to (10)).

As the charging of the charged amount is completed, the electric vehicle charging apparatus 100 generates the charging completion information and transmits it to the management server 200 through the broadband communication network (refer to (11)). The charging completion information may further include, for example, information such as a charging device ID, a charging amount, charging time of the charging vehicle information (car ID), and other payment information (change payment information).

The control server 205 of the management server 200 updates the vehicle management item corresponding to the vehicle ID using the received charge completion information and generates charger utilization information to be transmitted to the user (refer to (12)).

For example, the control server (control unit 205) of the management server 200 searches the vehicle charge management DB for the vehicle management item corresponding to the vehicle ID of the charged vehicle information, And generates and updates charging history information. The new charging history information includes a charging device ID (this ID can be received or mapped to a communication channel when the communication channel is connected), charging time (time), charging amount, charging cost (charging amount) Corresponding information in accordance with the information on the charging history information).

The control server (control unit 205) of the management server 200 also receives the charger usage information including the charging device ID, the charging timing, the charging amount, the car ID, the charging cost, And transmits it to the portable terminal 300 of the user corresponding to the retrieved electric car ID (refer to 13). For example, the control server (control unit 205) of the management server 200 extracts the IP address or mobile phone number of the portable terminal 300 of the user using the user identification information of the vehicle management item corresponding to the car ID And the charger utilization information can be transmitted using the extracted identifier as the destination address.

On the other hand, the control server (control unit 205) of the management server 200 can further transmit the alarm message to the portable terminal 300 of the user by further utilizing the vehicle status information of the searched vehicle management item. For example, the control server (205) of the management server (200) searches the vehicle management item corresponding to the vehicle ID included in the request or information upon receiving the payment request or the charge completion information, Can be extracted.

When the extracted vehicle state information is set to an abnormal state (e.g., stolen / lost state), the management server 200 (the control unit 205 of the control server 205) 100 can be transmitted to the portable terminal 300 of the user of the vehicle management item and the portable terminal 300 can output the alarm message to the display, speaker, buzzer, etc. have.

The portable terminal 300 receives the charger usage information and the alarm message from the management server 200 and displays it (see 14) so that the user can confirm the charging status, the abnormal status, and the like.

When the cumulative amount of charge reaches the amount of charge (corresponding to the amount of charge at the time of settlement) Block output. For example, the control unit 119 controls the selector 115-3 to shut off the output of the charging power supply and set the charging power supply circuit 115-1 of the charging type to the sleep mode.

The control unit 119 can output the guidance message to the adapter holder 157 through the output unit 103, requesting that the connector adapter 151 be embedded.

The user can mount the connector adapter 151 on the adapter holder 157 and press the release button 153-5 included in the base connector 153. [ The control unit 119 separates the connector adapter 151 from the base connector 153 simultaneously through the adapter fixing means control signal and the holder fixing means control signal as recognizing the user input from the separation button 153-5, The connector adapter 151 can be fixed to the connector 157.

The adapter holder 157 can further output to the control unit 119 a signal indicating that the connector adapter 151 is mounted. For example, the adapter holder 157 may output a signal that is generated differently depending on the connection and disconnection of the connector adapter 151 to the controller 119. The control unit 119 recognizes the user input from the separation button 153-5 and when recognizing from the received signal that the connector adapter 151 is mounted on the adapter holder 157, -3 can be controlled to separate the base connector 153 from the connector adapter 151 and control the holder fixing means 157-1 to fix the connector adapter 151 to the adapter holder 157. [

Thereafter, the user can mount the base connector 153 on the holder of the base connector 153 through the guidance from the output unit 103 or the like.

Upon completion of the charging, the controller 119 generates charging completion information and transmits it to the management server 200 (S70). The charging completion information may include, for example, information such as a charging device ID, a charging amount, charging vehicle information (car ID), charging time, and other payment information.

The transmitted charge completion information may then be transmitted to the portable terminal 300 of the user.

According to the configuration and control of the electric vehicle charging apparatus 100, it is possible to dynamically configure and charge the connector that matches the charging type economically and efficiently without having to provide a separate charging connector depending on the charging type.
