Abstract
A feed control device includes a contact device, an output detector, a contact weld sensor, and an alarm device. The output detector is configured to detect the presence of power feeding into the side of an electrically-powered car from an external power supply. The contact weld sensor is configured to sense that the contact device is welded based on a detection result of the output detector if detecting the presence of power feeding from the external power supply to a feed line for the contact device when a state signal representing charge permission is not entered. The alarm device is configured, if the contact weld sensor senses that the contact device is welded, to indicate the occurrence of weld to the outside.
