A vehicle power supply device includes a backup power supply to which power is supplied from a battery mounted in the vehicle, a boost unit that boosts a voltage of the backup power supply to a boost voltage, a motor drive unit that is connected to the battery and the boost unit and is capable of driving an electric motor by being supplied with power from either the battery or the boost unit, whichever has a higher voltage, and a control unit that controls operation of the boost unit. When it is determined that a predetermined boost condition is satisfied, the control unit controls the boost unit to boost the voltage of the backup power supply to a voltage higher than a rated voltage of the battery.
