Title:
POWER SUPPLY CONTROL DEVICE, POWER SUPPLY CONTROL METHOD, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/101012
Kind Code:
A1
Abstract:
A power supply control device (12) controls the supply of power, which is supplied via an electric wire (W1). A control unit of a microcomputer (23) periodically fetches an electric wire current value flowing in the electric wire (W1), and calculates the square value of the fetched electric wire current value. The control unit of the microcomputer (23) calculates the electric wire temperature of the electric wire (W1) each time n (n: integer of 2 or greater) periods relating to fetching of the electric wire current elapse. The control unit of the microcomputer (23) determines whether or not the integrated value of the square value of k items, calculated at the kth (k: natural number of n or less) period from the first period of the n periods, is an integrated threshold value or greater. The control unit of the microcomputer (23) changes the integrated threshold value to be a smaller value the higher that the calculated electric wire temperature is.
