PROBLEM TO BE SOLVED: To provide a charge/discharge cable which can be used both in charging and discharging a storage battery in a vehicle.SOLUTION: A charge/discharge cable 10 is formed by connecting a power supply plug 15 and a charging/discharging connector 13 by a cable. The charge/discharge cable 10 includes a plug socket 25 to which electrical equipment can be connected. The charge/discharge cable 10 also includes a control unit 17 which includes: a charging circuit composed of a first power supply circuit 28 and a first switch 30; a discharging circuit composed of a second power supply circuit 32 and a second switch 34; and a control circuit 37 for controlling open/close of the first switch 30 and second switch 34, and which switches charging and discharging. Concretely, the control unit 17 operates using power from the first power supply circuit 28 and puts the first switch 30 into a close state to thereby put a charging power supply line 26 into a conduction state, when performing charging, and operates using power from the second power supply circuit 32 and puts the second switch 34 into a close state to thereby put a discharging power supply line 26 into a conduction state, when performing discharging. |
