Abstract
An ECU of a vehicle performs processing for diagnosing sticking of a charge relay with an SMR being open. The sticking diagnosis processing is performed while electric power is being supplied from a DC power feed facility to the vehicle. The sticking diagnosis processing includes both-element sticking diagnosis processing and one-element sticking diagnosis processing. The ECU performs both-element sticking diagnosis processing by outputting an output command to the DC power feed facility. When it is determined that both of the charge relays have not stuck in the both-element sticking diagnosis processing, the ECU performs one-element sticking diagnosis processing and diagnoses whether or not sticking has occurred in each of the charge relays.
