Title:
POWER SUPPLY CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/045304
Kind Code:
A1
Abstract:
In this power supply control device, a temperature calculation circuit (55) calculates the wire temperature of a wire (W), on the basis of a current value of a current flowing through the wire (W). When the wire temperature calculated by the temperature calculation circuit (55) is less than a temperature threshold, a drive unit (52) switches a switch (50) on or off according to content indicated by a control signal output by a communication circuit. When the wire temperature calculated by the temperature calculation circuit (55) is equal to or higher than the temperature threshold, the drive unit (52) switches the switch (50) off regardless of the content indicated by the control signal output by the communication circuit.
