Device for detecting abnormality of wire harness for vehicle and power supply device for vehicle

摘要

In a device for detecting the abnormality of a wire harness or a power supply device for a motor vehicle, a temperature fuse which blows out when a temperature exceeds a certain value is arranged within or adjacently to a wire harness. By detecting the presence or absence of break of the temperature fuse, abnormality of the wire harness is detected. Thus, deterioration of the wire harness due to rare short can be avoided.
