To provide an on-vehicle backup power source control device or an on-vehicle backup power source which can report the state of a power storage part to the outside in an excellent manner while reducing the cost and the size.SOLUTION: A control device 20 applies voltage from a power storage part 92 to a backup target load 94 when a main power source 91 fails. The control device 20 includes a charging/discharging unit 35 that charges the power storage part 92 or discharges the power storage part 92, a voltage detection unit 38 that detects the voltage of the power storage part 92, a control unit 39 that controls the operation of the charging/discharging unit 35, and a signal blocking unit 37 that blocks output of a signal from the control unit 39 to the outside when a voltage value Vout of the power storage part 92 detected by the voltage detection unit 38 is less than a prescribed first threshold Th1.SELECTED DRAWING: Figure 1
【課題】コストやサイズを抑えつつ、蓄電部の状態を外部に良好に通知することができる車載用のバックアップ電源制御装置、又は車載用のバックアップ電源を提供する。【解決手段】制御装置20は、主電源91が失陥した際にバックアップ対象負荷94に蓄電部92から電圧を印加する。制御装置20は蓄電部92の充電、又は蓄電部92からの放電をする充放電部35と、蓄電部92の電圧を検出する電圧検出部38と、充放電部35の動作を制御する制御部39と、電圧検出部38が検出した蓄電部92の電圧値Voutが所定の第1閾値Th1よりも小さい場合、制御部39の外部へ信号を出力することを遮断する信号遮断部37とを備える。【選択図】図1
