PROBLEM TO BE SOLVED: To secure data required for investigation of causes of an abnormality while reducing a processing load associated with data transmission.SOLUTION: A controller of a power supply device includes a plurality of measuring units, a log acquisition processing unit, an abnormality detection processing unit, and a transmission log creation processing unit, and a log transmission processing unit. The plurality of measuring units can respectively measure a plurality of kinds of data related to power supply. The log acquisition processing unit can store the data measured by the measuring units in a measurement log storage unit and obtain a measurement log. The abnormality detection processing unit can detect a plurality of abnormalities related to the power supply on the basis of the data. The transmission log creation processing unit can create, when an abnormality is detected, a transmission log corresponding to the type of the detected abnormality from the data stored in the measurement log storage unit. The log transmission processing unit can transmit, when the abnormality is detected, the transmission log to a rewritable nonvolatile storage device.SELECTED DRAWING: Figure 1 |
