| description | [Subject Matter]In a vehicle power supply device mounted on a vehicle and obtaining a low voltage power supply from a high voltage power supply via a step-down means, electric shock to the human body is prevented without using an insulating means such as a transformer.[Solution(s)]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 resistance from the high voltage power supply to the ground is measured when the high voltage circuit is cut by the cutoff means placed between the high voltage power supply and the high-voltage load device. When the value less than a predetermined value, the connection between the high voltage power supply and the low-voltage load device is interrupted, so that electric shock is prevented. |
