Claim 0:
1. A power supply control device for supplying electrical power to a load, the power supply control device includes a switching unit that switches on or off a switch disposed on a wire connecting the power supply control device to the load, comprising:
an output unit that outputs a control signal indicating whether the switch is to be on or off; and
a first temperature calculation unit that calculates a wire temperature of the wire based on a current value of a current flowing through the wire, the first temperature calculation unit interposed between the output unit and the switch,
wherein, if the wire temperature calculated by the first temperature calculation unit is lower than a temperature threshold value, the switching unit switches on or off the switch in accordance with content indicated by the control signal output by the output unit, and
if the wire temperature calculated by the first temperature calculation unit is higher than or equal to the temperature threshold value, the switching unit switches off the switch independently of the content indicated by the control signal output by the output unit.
