To provide a power source management device and a power source management method capable of reliably shutting off a relay upon abnormality occurrence.SOLUTION: A power source management device according to an embodiment includes a control part and a monitoring part. The control part controls driving of a relay provided between a power source and a load. Upon detection of operation abnormality of the control part, the monitoring part resets the control part, thereby causing the control part to shut off the relay. The control part also includes a CPU self-diagnosis part which diagnoses whether or not any abnormality is occurring and which notifies abnormality to the monitoring part, if any. Upon reception of notification of the abnormality from the CPU self-diagnosis part, the monitoring part instead of the control part shuts off the relay.SELECTED DRAWING: Figure 3
【課題】異常発生時に、リレーを確実に遮断できる電源管理装置および電源管理方法を提供すること。【解決手段】実施形態に係る電源管理装置は、制御部と、監視部とを備える。制御部は、電源と負荷との間に設けられるリレーの駆動を制御する。監視部は、制御部の動作異常が検出された場合に、制御部をリセットすることで制御部にリレーを遮断させる。また、制御部は、制御部内部で生じる異常の有無を診断し、異常を検出した場合に、監視部へ通知するCPU自己診断部を備える。監視部は、CPU自己診断部による異常の通知を受け付けた場合に、制御部に代えてリレーを遮断する。【選択図】図3
