PROBLEM TO BE SOLVED: To provide an abnormality determination device of a power supply device, which can quickly determine existence or nonexistence of an abnormality in the power supply device.SOLUTION: A power supply device comprises an ISG (Integrated Starter Generator) generating electric power by power of an engine mounted on a vehicle, a battery configured capable of being charged with the electric power generated by the ISG and supplying the electric power to an electric load, and a current sensor detecting discharge from the battery. An abnormality determination device of the power supply device comprises an ECU carrying out abnormality determination of the power supply device. The ECU gives the ISG power generation instructions to generate electric power enabling operation of the electric load, and when discharge from the battery is detected by the current sensor, determines that the power supply device has an abnormality.SELECTED DRAWING: Figure 2
【課題】電源装置の異常の有無を迅速に判定することができる電源装置の異常判定装置を提供すること。【解決手段】車両に搭載されたエンジンの動力により発電を行うISGと、ISGにより発電された電力を充電可能に構成され電気負荷に電力を供給するバッテリと、バッテリからの放電を検出する電流センサとを備えた電源装置の異常判定装置であって、電源装置の異常判定を行うECUを備え、ECUは、電気負荷を作動可能な電力を発電するようISGに対して発電指示をしており、かつ電流センサによりバッテリからの放電が検出された場合に、電源装置に異常があると判定する。【選択図】図2
