Abstract
A control apparatus for a vehicle, wherein a detection signal, indicating the connection state of an external power feeding device 100 to an external charging connection unit 5 of a vehicle 1, is supplied from a connection state detection signal generating unit 11 to a storage device management control unit 10 and a power converter control unit 8. When detection signal indicating that an operation to release a lock mechanism 108, which locks the external power feeding device 100 connected to the external charging connection unit 5, has been performed is received from the connection state detection signal generating unit 11, the power converter control unit 8 controls a power converter 7, which feeds power from the external power feeding device 100 to an electric storage device 3, to a power feeding shutoff operation mode, independently of a charging control command received from the storage apparatus management control unit 10.
