A vehicle power supply device (1) is provided with: a backup power supply (6) to which power is supplied from an in-vehicle battery (3); a step-up unit (20) that steps up the voltage of the backup power supply (6) to a step-up voltage (Vb); a motor drive unit (7) that is connected to the battery (3) and the step-up unit (20), and that can drive the electric motor (2) by supplying power from one of the battery (3) and the step-up unit (20) having a higher voltage; and a control unit (8) that controls the operation of the boosting unit (20). When the control unit (8) determines that the predetermined step-up condition is satisfied, the control unit (8) controls the step-up unit (20) to step up the voltage of the backup power supply (6) to a voltage greater than the rated voltage of the battery (3).

    车辆用电源装置(1)具备:备用电源(6),由车载的电池(3)供给电力;升压部(20),将备用电源(6)的电压升压至升压电压(Vb);马达驱动部(7),与电池(3)和升压部(20)连接,能由电池(3)和升压部(20)中电压高的一方供给电力来驱动电动马达(2);以及控制部(8),控制升压部(20)的工作。控制部(8)在判定为规定的升压条件成立时,控制升压部(20)来使备用电源(6)的电压升压至比电池(3)的额定电压大的电压。
