Description

This invention relates to an electric vehicle charging system, a first control device, a second control device, an electric vehicle charging method, and a program. Recently, electric vehicles (EVs) have been gaining popularity. Along with this, charging services for EVs are also becoming more widespread, and various technologies for providing these services are being proposed. For example, in the technology described in Patent Document 1, the charging application transmits pre-registered user authentication information to the charging service provider server and payment information to the payment service provider server. The charging service provider server described in Patent Document 1, after confirming the validity of the authentication information obtained from the portable terminal by the user information processing unit and receiving notification from the portable terminal that the payment information is valid, requests the charger to start charging based on OCPP (Open Charge Point Protocol). For example, in the technology described in Patent Document 2, the charger is equipped with an IC card reader. In the technology described in Patent Document 2, when a user touches (brings close to or touches) an IC card to the IC card reader of the charger, the charger reads the IC card's ID using the IC card reader. When the communication unit of the charger receives an authentication response of the card ID from the server, it notifies the charging control unit of this. For example, in the technology described in Patent Document 3, a charging application for a portable terminal manages authentication information in a memory area managed by the application, and when the charging service starts, the portable terminal transmits this authentication information. The user information processing unit described in Patent Document 3 compares the received authentication information with the user authentication information managed in the database, and if the two match, it authenticates the user, considering the authentication information received from the portable terminal to be legitimate.
