To provide a power supply controller and a power supply control method that can prevent an electric shock due to a leak of electricity.SOLUTION: A power supply controller comprises a control part. The control part turns off a power supply system if a vehicle stops on occurrence of a ground fault and the driver leaves the vehicle with the power supply on. The control part comprises a first system which supplies electric power from a main power supply to a first load and a second system which supplies electric power from a subordinate power supply to a second load. The control part turns off a switch for secondary-side battery which connects the subordinate power supply to the second system after the ground fault of the first system, and turns off a switch for primary-side battery which connects the main power supply to the first system after a ground fault of the second system.SELECTED DRAWING: Figure 1
【課題】漏電による感電を防止することができる電源制御装置および電源制御方法を提供する。【解決手段】実施形態の一態様に係る電源制御装置は、制御部を備える。制御部は、地絡が発生したときに車両が停車し、電源がオン状態のまま運転者が降車した場合は電源系統をオフする。主電源から第1負荷に電力を供給する第1系統と、副電源から第2負荷に電力を供給する第2系統とを備え、制御部は、第1系統の地絡後であれば、副電源を第2系統に接続する2次側電池用スイッチをオフし、第2系統の地絡後であれば、主電源を第1系統に接続する1次側電池用スイッチをオフする。【選択図】図1
