Title:
IN-VEHICLE POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/230424
Kind Code:
A1
Abstract:
The in-vehicle power supply device according to the present disclosure is provided with: an input unit; a charging/discharging circuit connected to the input unit; a first output unit connected through a first switching unit and a first cut-off unit to the charging/discharging circuit; a second output unit connected through a second switching unit and a second cut-off unit to the charging/discharging circuit; and a control unit connected to the input unit, the first output unit, and the second output unit and controlling the charging/discharging circuit, the first switching unit, the first cut-off unit, the second switching unit, and the second cut-off unit. When the control unit detects that the voltage of the first output unit has reached a voltage lower than a first load threshold voltage, the first cut-off unit is switched from a connection state to a cut-off state. After a first predetermined period has elapsed from when the control unit detected that the voltage of the first output unit had reached the voltage lower than the first load threshold voltage, the second switching unit is switched from a high resistance conduction state to a low resistance conduction state that is a resistance state lower than the high resistance conduction state.
