PROBLEM TO BE SOLVED: To provide a function of simply determining the deterioration state of a power supply device.SOLUTION: A device for a simple deterioration determination method for a power supply device includes: an information communication device that is electrically connected to an output terminal of the power supply device; a detection device that detects a voltage/current from the output terminal of the power supply device; and a communication device that is connected to the information communication device and monitors the status of the information communication device. The detection device measures a rush current of the output terminal of the power supply device when the power supply device is powered on, calculates a polynomial on the basis of the measured rush current, and transfers the calculated polynomial and the ID of the information communication device to the communication device. The communication device extracts a predetermined polynomial of the power supply device, which corresponds to the transferred ID of the information communication device, from a storage unit, calculates a difference between the extracted predetermined polynomial and transferred polynomial, generates a comparison result on the basis of the difference, and displays a comparison result. |
