PROBLEM TO BE SOLVED: To provide a power control device and a power control method, for continuously supplying electric power to an in-vehicle device that needs power supply without adding a power supply, even if an electrical failure occurs in a power supply system that supplies power to each of a plurality of in-vehicle devices from at least one of the plurality of power supplies.SOLUTION: A power control device 130 is applied to a power supply system 100 that supplies power from the at least one of a plurality of power supply lines 210, 212 by a plurality of power supplies 110, 120 and power lines 200, 202 respectively connected to power sources to the in-vehicle devices 10, 20 through 24. When detecting that an electrical failure has occurred in one of the power supply systems, the power control device turns off a switch that connects the power supply system having the failure and another power supply system.SELECTED DRAWING: Figure 1
【課題】複数の電源の少なくともいずれかから複数の車載装置のそれぞれに電力を供給する電力供給系統に電気的な失陥が生じても、電源を追加することなく電力供給の必要な車載装置に継続して電力を供給する。【解決手段】電力制御装置130は、複数の電源110、120と電源のそれぞれに接続する電力線200、202とによる複数の電力供給系統210、212の少なくともいずれかから、車載装置10、20〜24に電力を供給する電力供給システム100に適用される。電力制御装置は、電力供給系統のいずれかに電気的な失陥が発生したことを検出すると、失陥が発生した電力供給系統と他の電力供給系統とを接続するスイッチをオフにする。【選択図】図1
