B2

PROBLEM TO BE SOLVED: To prevent damage on equipment due to bonding to ON of a relay.SOLUTION: A power feeding control device is mounted on a vehicle which can supply power between a device connected to a terminal and an onboard battery, through a first terminal and a second terminal. It includes charge control means, first power feeding control means, second power feeding control means, abnormality detecting means, and power feeding prohibition control means. The charge control means supplies power through a path in which the first terminal, a first connection part, a first conversion part for conversion from AC to DC, and a battery are connected in this order. The first power feeding control means does it through a path in which the battery, a second conversion part for conversion from DC to AC, a second connection part, a first relay, the first connection part, and the first terminal are connected in this order. The second power feeding control means does it through a path in which the battery, the second conversion part, the second connection part, a second relay, and the second terminal are connected in this order. The power feeding prohibition control means, when bonding to ON of the first relay is detected by the abnormality detecting means before starting of power supply by the second power feeding control means, prohibits power supply by the second power feeding control means.
