When charging power is supplied, the wireless charging pad 302 converts it into a magnetic field for charging and radiates the charging power wirelessly into space. The electric vehicle parked on the general parking surface 202 receives the magnetic field transmitted from the wireless charging pad 302 using the wireless charging coil and converts it into electric power to charge the electric vehicle. Here, it is assumed that the electric vehicle is equipped with a wireless charging means.

When wireless charging starts, the settlement unit 107 starts calculating a charging fee according to the charging power.

When wireless charging starts, the wireless charging pad 302 detects a load state using a current sensor. Here, the load state detection determines whether the electric vehicle, which is the load, receives wireless charging power properly, or whether the parking position of the electric vehicle is wrong or the user selects the wrong parking surface and the wireless charging power is not supplied to the electric vehicle and is dissipated in the space. detect Here, since a method of detecting a load state and a no-load state using a current sensor is a well-known technique in the electric field, a detailed description thereof will be omitted.

The charging state checking unit 103 of the charging kiosk 100 checks the charging state using the load state information detected through the wireless charging pad 302, and transmits the checked charging state information to the charging control unit 105. . Here, the load state information may be divided into a load state and a no-load state.

Here, the display unit 106 may display remaining charging time during charging.

In contrast, when the load state information is no-load state information, it is determined that charging is not normally performed, and charging is stopped immediately, and a charging error warning signal is generated and transmitted to the alarm generating unit 108 .

The alarm generating unit 108 provides a charging error warning according to the charging error warning signal generated by the charging controller 105 so that the user can recognize a charging error situation. Here, the charging error alarm may generate an audible alarm through an alarm sound and a visual alarm displaying a charging error through an LED or display unit 106 . Audible and visual alarms may be used in combination or either one may be used.

When a charging error alarm is generated by the alarm generating unit 108, the user checks whether the charging position of the electric vehicle is wrong or the wrong charging parking surface is selected, corrects the error, and recharges again. ask for Here, by drawing a figure displaying a wireless charging pad or displaying information indicating an electric car parking position on the general parking surface, the user can be induced to accurately park the electric car at the charging position. If the wrong parking surface is selected, the charging error can be resolved by reselecting the parking surface to be charged through the user interface 101.

Thereafter, when charging is normally completed, the settlement unit 107 interlocks with the charging control unit 105 to calculate the electric vehicle charging fee. It is assumed that the electric vehicle charging fee settlement method is selected by the user in advance.

Meanwhile, another feature of the present invention is that the user can recognize charging information about charging of the electric vehicle in real time. That is, when charging normally starts, the charging control unit 105 generates charging information (charging start time, charging completion time, remaining charging time, etc.) and transmits it to the charging information providing unit 109. The charging information providing unit 109 transmits the received charging information to the user terminal 500 so that the user can recognize the charging state in real time. Here, the charging information provider 109 may transmit charging information to the user terminal 500 in real time using long-distance wireless communication or short-range wireless communication.

When wireless charging starts, the wireless charging pad 820 detects a load state using a current sensor. Here, the load state detection determines whether the electric vehicle, which is the load, receives wireless charging power properly, or whether the parking position of the electric vehicle is wrong or the user selects the wrong parking surface and the wireless charging power is not supplied to the electric vehicle and is dissipated in the space. detect Here, since a method of detecting a load state and a no-load state using a current sensor is a well-known technique in the electric field, a detailed description thereof will be omitted.

The charging state checking unit 603 of the charging kiosk 600 checks the charging state using the load state information detected through the wireless charging unit 800 and transmits the checked charging state information to the charging control unit 605. Here, the load state information may be divided into a load state and a no-load state.

The charging control unit 605 determines the load state of the parking surface to be charged through the charging status checking unit 603, and displays it through the display unit 606 when charging is normally performed. Here, the display unit 606 may display remaining charging time during charging.

In contrast, when the load state information is no-load state information, it is determined that charging is not normally performed, and charging is stopped immediately, and a charging error warning signal is generated and transmitted to the alarm generating unit 608 .

The alarm generating unit 608 provides a charging error warning according to the charging error warning signal generated by the charging controller 605 so that the user can recognize a charging error situation. Here, the charging error alarm may generate an audible alarm through an alarm sound and a visual alarm displaying a charging error through an LED or display unit 606 . Audible and visual alarms may be used in combination or either one may be used.

When a charging error alarm is generated by the alarm generating unit 608, the user checks whether the charging position of the electric vehicle is wrong or the wrong charging parking surface is selected, corrects the error, and recharges again. ask for Here, by drawing a figure displaying a wireless charging pad or displaying information indicating an electric car parking position on the general parking surface, the user can be induced to accurately park the electric car at the charging position. If the wrong parking surface is selected, the charging error can be resolved by reselecting the parking surface to be charged through the user interface unit 601.

Thereafter, when charging is normally completed, the settlement unit 607 interlocks with the charging control unit 605 to calculate the electric vehicle charging fee. It is assumed that the electric vehicle charging fee calculation method is selected by the user in advance.

Meanwhile, another feature of the present invention is that the user can recognize charging information in real time about charging of the electric vehicle. That is, when charging normally starts, the charging control unit 605 generates charging information (charging start time, charging completion time, remaining charging time, etc.) and transmits it to the charging information providing unit 610. The charging information providing unit 610 transmits the received charging information to the user terminal 1000 so that the user can recognize the charging state in real time. Here, the charging information providing unit 610 may transmit the charging information to the user terminal 1000 in real time using long-distance wireless communication or short-range wireless communication.

According to the present invention described above, the electric vehicle can be charged in a general parking lot of a public parking lot, so that the electric vehicle can be conveniently charged even in a parking lot without a dedicated electric vehicle parking space.

In addition, according to the present invention, it is possible to charge an electric vehicle in the parking surface of a general public parking lot, thereby promoting demand for electric vehicles and improving user convenience.
