  • Patent number: 11518323
    Abstract: When an outlet is shut off, an ECU monitors whether a restoration condition for restoring the outlet is satisfied. When the restoration condition is not satisfied, the ECU shifts a process to return. When the restoration condition is satisfied, the ECU restores the outlet for which the restoration condition is satisfied. As the restoration condition, a condition that an external device connected to the outlet is removed with the outlet being shut off or a condition that the external device connected to the outlet is removed and then the external device is connected to the outlet with the outlet being shut off can be adopted.
