Description

[Technical Field]

[0001] The present invention claims the benefit of priority based on Korean Patent Application No. 10-2022-0149083, filed on November 9, 2022, and all contents disclosed in the documents of this Korean patent application are incorporated herein by reference.

[0002] SUMMARY OF THE INVENTION The embodiments disclosed herein relate to a server and a charging system including the server. [Background technology]

[0003] As environmental issues become more important, the use of environmentally friendly electric vehicles is expanding. Accordingly, infrastructure for the use of electric vehicles (e.g., chargers or charging stations) is being increasingly built. For example, charging systems are becoming more widespread, in which users of electric vehicles authenticate themselves using an external identification means (EIM) system based on an RFID card or QR code (registered trademark), or a plug and charge (PnC) system based on a certificate in the electric vehicle. Once authentication is complete, the electric vehicle is charged with power provided by a charger.

[0004] Meanwhile, the PnC method refers to a charging technology in which authentication and payment are performed automatically when charging an electric vehicle. The advantage of PnC charging is that users do not have to go through various processes to identify themselves, but the disadvantage is that it can only be used in vehicles that support PnC, and even in vehicles that support PnC, a charger that is linked to the vehicle must be used.

According to an embodiment, the charger 200 may store the amount of power used to charge the target device 100. The charger 200 may generate the second charging information based on the amount of power used. The second charging information may include the amount of power used by the charger 200. According to an embodiment, the second charging information may include charging status information of the target device 100. The charger 200 may transmit the generated second charging information to the charging server 500. After operation S132, operation S133 may be performed.

[0095] In operation S133, the charging server 500 may transmit the second charging information to the management server 400. The charging server 500 may transmit the second charging information to the management server 400. According to an embodiment, the charging server 500 may convert the second charging information received from the charger 200, but is not limited thereto. After operation S133, operation S134 may be performed.

[0096] In operation S134, the management server 400 can calculate the cost by integrating the first charging information and the second charging information. The management server 400 can calculate the charging cost based on the first charging information and the second charging information. The management server 400 can calculate the charging cost based on the power usage amount obtained by integrating the first charging information and the second charging information. After operation S134, operation S135 can be performed.

[0097] In operation S135, the management server 400 can charge a fee to the user of the target device 100. The management server 400 can charge a charging fee to the user of the target device 100 using a preset payment method. The management server 400 can recognize the information collection device 300 to identify the user, and extract data related to the identified user from the stored user data. The management server 400 can charge a fee to the user based on the extracted data.
