Abstract
A data updating system according to one embodiment of the present invention carries out, in a user terminal, an authentication request process (S5) for transmitting, to a central server, authentication information including at least an authentication code displayed on a charging stand, user information registered previously, and location information of the charging stand and the user terminal. Said system also carries out, in the central server, an authentication process (S6) for authenticating the validity of the authentication information, and if the authentication process is successful, a distribution process (S10) for causing the charging stand to download software for updating, and carries out, in the charging stand once a charging cable has been connected to a vehicle, an authentication code provision process (S2) for displaying the authentication code, and a data updating process (S11) for updating software in the vehicle to be updated by sending the downloaded software via a communication line to the vehicle to be updated.
