PROBLEM TO BE SOLVED: To provide a power supply control device, a power supply control method, and a computer program which can perform a determination by using a wire current value nearly equivalent to a determination according to a wire temperature.SOLUTION: A power supply control device 12 controlling a power supply through an electric wire W1 has a control unit in a micro computer 23 which periodically acquires a wire current value flowing through the electric wire. The control unit calculates a square value of the wire current value acquired by an acquisition unit, calculates a wire temperature of the electric wire every time n (n: integer equal to or more than 2) periods according to an acquisition of the wire current value lapse, determines whether or not an integrated value of the square value of k (k: natural number equal to or less than n) calculated by a squire value calculating unit in a k-th period from a first period of n periods is equal to or more than an integrated threshold value, and changes the integrated threshold value smaller as the wire temperature calculated by a temperature calculating unit gets higher.SELECTED DRAWING: Figure 1
