The charging medium may directly transmit the user information and the charging information to the central server or transmit the user information to the central server through a smart gateway corresponding to the user information.

Alternatively, the charging medium may transmit the user information and the charging information to the central server, and transmit the charging information or the user information and the charging information to the smart gateway. As a result, the smart gateway can also recognize the fact that the user charges the electric vehicle.

Subsequently, the central server obtains information of the user through the user information, for example, information on the number of households, compares the user information with stored user information, and approves charging when the user is an apartment resident ( S808). Although this approval may be manually performed by an administrator, it is preferable that the central server compares pre-stored information with the user information for fast charging.

According to another embodiment, when it is determined through the user information that the user is not an apartment resident but a resident of another apartment, the central server transmits information related to charging to the central server corresponding to the other apartment and approves the charging. may be

Subsequently, when the charging approval is completed, the central server transmits approval information indicating that the approval has been completed to the charging medium, and according to the charging approval, electricity flows to the charging station where the electric vehicle is parked to charge the electric vehicle. It is charged (S810). At this time, while charging, charging information such as the location of the charging station where the electric vehicle is charged (charging location), the remaining time until charging is completed (charging completion time), etc. can be transmitted to the smart gateway, and as a result, the user can be at home The charging location and charging completion time can be identified. Of course, this charging information may be transmitted in step S806 and may not be transmitted in this step.

In addition, the charging information may be transmitted to the user terminal through the smart gateway or the central server as well as the smart gateway.

Subsequently, when the charging is completed, electricity to the charging station is cut off (S812), and the charging medium can transmit charging completion information indicating that the charging has been completed to the smart gateway and the central server.

Subsequently, the central server may generate a charge according to the charging amount and add the generated charge to the management fee of the user (S814). Of course, the central server may transmit the generated charge to the smart gateway, or may directly charge it without adding it to the management fee.

In summary, the electric vehicle charging system of the present invention can conveniently charge an electric vehicle using the smart gateway and the central server.

In the above, the charge according to the charging of the electric vehicle is billed as a deferred payment, but the charging amount is charged to the charging card, and the charging amount may decrease according to the charging. However, from a convenient point of view, it is efficient to charge the charge according to the charge as a deferred payment.

Subsequently, the charging medium may acquire user information through the user's input or the charging card (S902), and transmit the user information and charging information to the central server of the apartment A.

Subsequently, the central server transmits the user information and the charging information to the central server of apartment B, approves charging, and the electric vehicle can be charged according to the charging approval (S904).

Subsequently, the central server of the apartment A may generate billing according to the charging amount (S906).

Subsequently, the central server of apartment A may transmit charging information including the generated charge to the central server of apartment B (S908). In this case, the central server of the apartment B may add the charge to the management fee and transfer at least a part of the charge to an account connected to the central server of the apartment A. Therefore, as the user recharges in another apartment, both the apartment A and the apartment B can earn profits. This process can be applied to both the first situation and the second situation.

However, in the case of the third situation, since the user's residence, etc. cannot be identified, the cost of charging can be immediately paid on site. For example, it can be billed by cash payment or card payment. In this case, the charging medium may include a card payment function.

In summary, the electric vehicle charging system of this embodiment can acquire information about the charging and charge even when a resident charges in another connected apartment.
