Zusammenfassung:	PROBLEM TO BE SOLVED: To appropriately control a process of detecting presence of welding of a contactor.SOLUTION: An ECU 61 of a power feed system 10, after stopping power feeding from an electric vehicle 11 to an inverter device 12, detects presence of welding of an external power feed contactor 33, and when detecting the welding of the external power feed contactor 33, prohibits actuation of the electric vehicle 11. The ECU 61, when receiving a first signal including a power feed-start signal for instructing start of power feed from the electric vehicle 11 to the inverter device 12, performs detection of welding. The ECU 61, when receiving a second signal, prohibits power feeding from the electric vehicle 11 to the inverter device 12 and detection of welding of the external power feed contactor 33, outputs an alarm, cuts off the external power feed contactor 33 and cuts off a battery contactor 31.
