Provided is a vehicle-mounted power supply control device that more accurately grasps the power supply capability of a power storage unit, prevents excessive prohibition of support operation, and reliably retains the capability that can be supplied to a first load. A control device (3) is provided with: a discharge circuit (20) that performs a support operation for supplying power from a power storage unit (92) to a first load (81) and a second load (82); a control unit (10) that causes the discharge circuit (20) to perform a support operation when a support condition is satisfied; and a voltage detection unit (32) that detects the output voltage of the power storage unit (92). When the supply of power to the second load (82) is stopped after the start of the support operation, the control unit (10) prohibits the support operation with respect to the second load (82) if the output voltage of the power storage unit (92) is less than a threshold voltage.
实现一种车载用电源控制装置,更准确地掌握蓄电部的电力的供给能力,防止支援动作的过度的禁止并且可靠地保留能够向第一负载进行供给的能力。控制装置(3)具备:放电电路(20),进行从蓄电部(92)向第一负载(81)及第二负载(82)供给电力的支援动作;控制部(10),在支援条件成立了的情况下使放电电路(20)进行支援动作;电压检测部(32),检测蓄电部(92)的输出电压。在支援动作开始后在向第二负载(82)的电力供给为停止状态时,在蓄电部(92)的输出电压小于阈值电压情况下,控制部(10)禁止对于第二负载(82)的支援动作。
