Abstract
When DC charging is completed, an ECU of a vehicle performs first diagnosis processing for diagnosing whether or not charge relays have stuck with an SMR being closed. In the first diagnosis processing, whether or not the charge relays have stuck is diagnosed based on an open/close command to the charge relays and a voltage applied to a charge port. When both of the charge relays are determined as having stuck in the first diagnosis processing, the ECU performs second diagnosis processing on the assumption that a DC power feed facility falls under a specific DC power feed facility. In the second diagnosis processing, whether or not the charge relays have stuck is diagnosed based on the open/close command to the charge relays, the voltage applied to the charge port (a first voltage), and a voltage (a second voltage) between a first power line and a second power line.
