Abstract
A charging cable includes: an abnormality detection unit that detects an abnormality in a charging cable; and a CCID controller that outputs a first control pilot signal to a control pilot signal line to notify a vehicle about a rated current of the charging cable. The first control pilot signal provides a notification about the rated current in a state where a duty ratio of the first control pilot signal is controlled to fall within a prescribed range while a frequency of the first control pilot signal is fixed to a specific value. When the abnormality detection unit detects an abnormality, the CCID controller outputs a second control pilot signal for notifying the vehicle about details of the detected abnormality to the control pilot signal line. The second control pilot signal is different in duty ratio from the first control pilot signal.
