Patent Images
1. A charging cable for an electric vehicle through which an electric storage device, provided in the vehicle and used for driving the vehicle, is charged from an external power supply, the charging cable comprising:
- a first coupler that connects the charging cable to a vehicle inlet provided in the vehicle;
a second coupler that connects the charging cable to the external power supply;
a control device that controls a usage history of the charging cable, wherein the control device includes;
a storage section that stores the usage history of the charging cable;
a detection section that detects a usage state of the charging cable and that updates the usage history based on the detected usage state;
a determination section that determines whether a service life limit of the charging cable has been exceeded based on the stored usage history and a reference value; and
an electric wire section that is provided between the first coupler and the control device and between the second coupler and the control device, through which electric power and a control signals pass.
