Provided is an in-vehicle backup power supply control device or an in-vehicle backup power supply capable of externally reporting the status of a power storage unit in a favorable manner while minimizing cost and size. When a main power supply (91) fails, a control device (20) applies a voltage from a power storage unit (92) to a backup subject load (94). The control device (20) is provided with: a charging/discharging unit (35) which charges the power storage unit (92) or discharges the power storage (92); a voltage detection unit (38) which detects the voltage of the power storage unit (92); a control unit (39) which controls the operation of the charging/discharging unit (35); and a signal interruption unit (37) which, when a voltage value (Vout) of the power storage unit (92) detected by the voltage detection unit (38) is less than a predetermined first threshold value (Th1), interrupts external signal output by the control unit (39).
提供一种能够抑制成本、尺寸并将蓄电部的状态向外部良好地通知的车载用的备用电源控制装置或车载用的备用电源。控制装置(20)在主电源(91)失灵时从蓄电部(92)向备用对象负载(94)施加电压。控制装置(20)具备:充放电部(35),进行蓄电部(92)的充电或从蓄电部(92)的放电;电压检测部(38),检测蓄电部(92)的电压;控制部(39),控制充放电部(35)的动作;及信号切断部(37),在电压检测部(38)检测出的蓄电部(92)的电压值(Vout)比规定的第一阈值(Th1)小的情况下,切断信号向控制部(39)的外部的输出。
