1. A vehicle charging system comprising:
a charging station including a cable-side connector;
a first vehicle including a first vehicle memory and a first electronic control unit (ECU), the first vehicle memory storing first vehicle identification information for identifying the first vehicle, and the first ECU including a first ECU memory storing first ECU identifying data for identifying the first ECU and first certificate data for receiving a charge service provided by the charging station;
a second vehicle including a second battery, a second vehicle-side connector, a second vehicle memory, and a second ECU, the second vehicle-side connector being configured to connect to the cable-side connector and charge power being supplied to the second battery by the connection, the second vehicle memory storing second vehicle identification information for identifying the second vehicle, and the second ECU including a second ECU memory storing second ECU identifying data for identifying the second ECU and second certificate data for receiving the charge service;
a management server including a first server memory storing a database and a first server processor connected to the first server memory, the database describing
(i) a first combination of the first vehicle identification information, the first ECU identifying data, first payment information of a first user of the first vehicle, and the first certificate data, and
(ii) a second combination of the second vehicle identification information, the second ECU identifying data, second payment information of a second user of the second vehicle, and the second certificate data;
a service server including a second server processor configured to issue the certificate data; and
a charging server including a third server processor and a third server memory storing the first and second certificate data, the charging server communicating with the charging station via an internet, wherein
in a case where the first ECU is removed from the first vehicle and the second vehicle is equipped with the first ECU instead of the second ECU,
the first server processor is configured to
acquire the second vehicle identification information and the first ECU identification information from the second vehicle,
determine that a combination of the second vehicle identification information and the first ECU identification information is not described in the database, and
transmit a command requesting issuance of third certificate data to the service server,
the second server processor is further configured to issue the third certificate data and transmit the third certificate data to the charging server and the management server,
the third server processor is configured to delete the first and second certificate data and store the third certificate data in the third server memory,
the first server processor is further configured to
delete the first and second combinations,
store a third combination of the second vehicle identification information, the first ECU identifying data, the second payment information, and the third certificate data in the database, and
transmit the third certificate data to the second vehicle equipped with the first ECU,
the first ECU is configured to
delete the first certificate data and store the third certificate data in the first ECU memory,
perform wired communication with the charging station in response to the second vehicle-side connector being connected to the cable-side connector,
encrypt the third certificate data, and
transmit the encrypted third certificate data to the charging server via the wired communication and the internet,
the third server processor is further configured to
authenticate the received third certificate data from the first ECU based on the stored third certificate data,
receive charging fee data from the charging station, and
transmit the third certificate data and the charging fee data to the management server via the service server, and
the first server processor is further configured to settle the charging fee by using the second payment information based on the third combination.
