PROBLEM TO BE SOLVED: To detect a state of a secondary cell even after an engine stops and to suppress power consumption of an apparatus itself.SOLUTION: A power supply management apparatus (a dark current monitor 11), managing a secondary cell 14 as a power supply mounted on a vehicle, includes: determination means (CPU 11a) which determines whether or not a system management unit (an engine ECU 12) managing the secondary cell 14 while the vehicle is operating has stopped its operation; and control means (CPU 11a) which detects a state of the secondary cell 14 when the determination means (CPU 11a) determines that the system management unit (the engine ECU 12) has stopped its operation and which controls a state of the vehicle on the basis of the detection result.SELECTED DRAWING: Figure 1

    【課題】エンジン停止後も二次電池の状態を検出するとともに、装置自体の消費電力を低減すること。【解決手段】車両に搭載された電源としての二次電池14を管理する電源管理装置(暗電流監視装置11)において、車両が動作中に二次電池14を管理するシステム管理ユニット(エンジンECU12)が動作を停止したか否かを判定する判定手段(CPU11a)と、判定手段(CPU11a)によってシステム管理ユニット(エンジンECU12)が動作を停止したと判定した場合、二次電池14の状態を検出し、検出結果に基づいて車両の状態を制御する制御手段(CPU11a)と、を有することを特徴とする。【選択図】図1
