Abstract: In a case where a connector of a power supply facility is connected to an inlet, an ECU is configured to control a potential of a pilot signal so as to request power supply to the power supply facility and to permit execution of external charging. Further, in a case where the ECU detects a feeding voltage from the power supply facility without requesting the power supply to the power supply facility, when it is detected that the feeding voltage is not output from the power supply facility in a state where the connector is connected to the inlet, the ECU permits the external charging.

Abstract: An inlet is configured to connect with a connector of a charging cable. An ECU is configured to switch between (i) a charging permitted state in which external charging is permitted and (ii) a charging non-permitted state in which external charging is not permitted. When the connector is in connection to the inlet, the ECU selects the charging permitted state in which external charging is permitted, even if a connector connection signal indicative of a state of connection between the connector and the inlet indicates a partially-connected state in which the connection between the connector and the inlet is not latched.

Abstract: This vehicle includes an inlet for performing external charging of a first method as well as a charging cord and a relay for performing external charging of a second method. During external charging of the first method, a battery charger is controlled such that electric current having a value smaller than or equal to a current value indicated by a pilot signal flows. During external charging of the second method, the relay is caused to conduct, and the battery charger is controlled such that electric current having a value smaller than or equal to a previously defined current value flows. Therefore, external charging of the first method and that of the second method can be selectively executed with a simple configuration.
