Provided is a backup device for a vehicle that can easily supply sufficient power to a load when power supply from a power supply unit is in a failure state. In a vehicle power supply system (100) provided with a power supply unit (20) for supplying power to a load (30), a vehicle backup device (10) performs a backup operation when power supply from the power supply unit (20) is in a failure state. The present invention is provided with: a charge/discharge unit (12) that charges and discharges a backup power supply (40) that includes a battery (41) and a capacitor (42) and is a different power supply from a power supply unit (20); and a control unit (11) that controls the charging/discharging unit (12). In the case of a failure state, the control unit (11) causes the charging/discharging unit (12) to perform a backup operation so as to supply power to the load (30) from the battery (41) and the capacitor (42).
提供一种车辆用备用装置,在来自电源部的电力供给成为失灵状态的情况下,容易向负载供给充足的电力。车辆用备用装置(10)在具备向负载(30)供给电力的电源部(20)的车辆用电源系统(100)中,在来自电源部(20)的电力供给成为失灵状态的情况下进行备用动作。具备:充放电部(12),进行包括电池(41)和电容器(42)且作为与电源部(20)不同的电源的备用电源(40)的充电和放电;及控制部(11),控制充放电部(12)。在成为失灵状态的情况下,控制部(11)使充放电部(12)进行备用动作,以将基于电池(41)和电容器(42)的电力供给到负载(30)。
