Abstract
An ECU includes a processor that controls transmission and reception of signals between a vehicle and a charging facility in accordance with a communication sequence defined in a charging standard. The processor transmits, to the charging facility, a regular signal for obtaining a charging permission from the charging facility, prior to a start of electric power supply from the charging facility to the vehicle. The processor starts charging control of a battery by the electric power supply from the charging facility, when the charging permission is obtained, and transmits, to the charging facility, a retry signal in which a part of the regular signal is modified in order to retry to obtain the charging permission, when the charging permission is not obtained.
