The control unit 140 may control the operation of the blocking unit 130 based on the information included in the signal received by the communication unit 150 or the charging request information input by the input unit 160. [

For example, when the load amount corresponding to the transformer load information received by the communication unit 150 is greater than the reference load amount, the controller 140 electrically connects the first port 110 and the second port 120 The blocking unit 130 can be controlled to be opened.

For example, the controller 140 determines the power supply voltage, the frequency, the DC / AC status, the wired / wireless mode, the charging mode, and / or the charging speed based on the charging request information input by the input unit 160 The switching point of the blocking unit 130 can be controlled, and charge information can be generated accordingly.

Here, the charging request information may include authentication request information, and thus may be transmitted to the server, the certification authority, or the settlement financial institution by the communication unit 150 for the authentication operation. The server, the certification authority or the settlement financial institution can check whether the driver of the electric vehicle is a driver subscribed to the electric vehicle charging transaction system by comparing the authentication request information with the stored information, generate authentication information based on the confirmation result, ). The authentication information can be used for state control of the cover 187. [

The sensor 165 may sense whether the charger shown in FIG. For example, the sensor 165 may be embedded in a cradle or exposed to the outside of the cradle, and may detect whether a charger is present at a predetermined position through a magnetic or optical method.

The sensing result of the sensor 165 may be transmitted to the controller 140. Thereafter, the controller 140 generates a control signal for driving the cover 187 according to the detection result of the sensor 165, and controls the state of the cover 187 according to the control signal. Thus, the safety of the charger can be improved, and the cover 187 can be prevented from unnecessarily interfering with the vehicle or the pedestrian.

The cover 187 may be changed from a closed state to an open state or from an open state to a closed state according to the control signal.

For example, the cover 187 may be controlled by the control unit 140 to change from a closed state to an open state when the authentication information received by the communication unit 150 corresponds to predetermined information. If the authentication information does not correspond to the predetermined information, the cover 187 may be locked so as not to be opened by an external physical force. Thus, theft of the charger can be effectively prevented.

For example, the cover 187 is changed from a closed state to a closed state after the blocking portion 130 is electrically connected between the first port 110 and the second port 120, May be controlled by the control unit 140 to be changed from a closed state to an open state after electrically opening the first port 110 and the second port 120. [ Accordingly, it is possible to prevent the cover 187 from unnecessarily interfering with the vehicle, the driver, or the pedestrian during the charging process.

According to the design, the cover 187 may be locked so as not to be opened by an external physical force when the cover 187 is changed to the closed state under the control of the controller 140. [ Thus, theft of the charger can be effectively prevented.

On the other hand, if the state of the cover 187 is not appropriately controlled by the control unit 140 or the control condition of the control unit 140 is stopped, the communication unit 150 can transmit the abnormal state information to the server , And can receive the operation interruption information. When the operation stop information is received by the communication unit 150, the electric vehicle charging apparatus 100 may be deactivated and the charging to the electric vehicle 300 may be stopped. Accordingly, integrated management of a plurality of electric vehicle charging apparatuses can be performed, and safety of each of the plurality of electric vehicle charging apparatuses can be improved.

For example, when the charging operation of the electric vehicle is terminated, the sensor 165 may be placed on the charger until the predetermined time elapses from the time when the first port 110 and the second port 120 are electrically opened. If it is not detected, the communication unit 150 may transmit abnormal state information to the server.
