A vehicle power supply device converts power from high voltage to low voltage by selectively connecting a predetermined power storage element group to a low voltage electric load from a high voltage power supply formed by connecting power storage elements in series. A leakage current from the high voltage power supply is measured during the dead time period when the power storage element group is not connected to the low voltage electric load. When the value exceeds a predetermined value, the connection between the power storage element group and the low-voltage electric load is interrupted, so that electric shock is prevented.

[Problem] To provide a vehicle power supply device that steps down a high-voltage power supply to obtain a low-voltage power supply for driving a low-voltage on-board device, wherein a stable low-voltage power supply can be obtained even when the voltage of a high-voltage storage means changes. [Solution] In a configuration in which power conversion from high voltage to low voltage is carried out by selectively connecting, from a high-voltage power supply formed by connecting storage elements in series, a predetermined storage element group to a low-voltage electric load, the number of storage elements is set such that, when the voltages of the storage elements are at the lowest value, the voltage of each storage element group is slightly higher than the rated operating voltage of a low-voltage electric load means. A rectifying means and a smoothing circuit that is composed of an inductor and a capacitor are provided on the output side of a switching means. As a result of controlling the ratio of on time and off time (dead time) of the switching means, a low-voltage power supply with stable voltage is formed that is not affected by changes in the voltages (SOC) of the storage elements.
