- a communication device configured to communicate with a terminal and a server that is a transmission source of the digital certificate;
- and
- a controller that writes the certificate information to the storage device upon receipt of the certificate information from the server, wherein
- when the server is requested to transmit the certificate information by the terminal, the controller is provided, by the terminal, with a notification about writing of the certificate information during writing of the certificate information to the storage device, and
- when the server is requested to transmit the certificate information via the communication device, the controller is not provided with the notification during writing of the certificate information to the storage device.

- a communication device configured to communicate with a server and a vehicle;
- and
- a display device that displays predetermined information, wherein
- the vehicle includes
- a power storage device, and
- a storage device that stores certificate information about a digital certificate used in a process for authentication in use of a power stand that performs power transmission between the power storage device and the power stand,
- the terminal further comprises a controller that, when requesting the server to transmit the certificate information via the communication device, displays, on the display device, information about writing of the certificate information received from the server during writing of the certificate information to the storage device, and
- the controller does not display the information about writing of the certificate information on the display device when the server is requested from the vehicle to write the certificate information.
