Document Type and Number:
Japanese Patent JP2023169182
Kind Code:
A
Abstract:
To provide a system and a program that excellently supply power to an on-vehicle device.SOLUTION: In a system including a monitoring battery, a drive recorder, a power cable, a cable and the like, and after-installed on a vehicle, a charge/discharge control unit 31 of a monitoring battery 3 controls a power supply path such that power is supplied from an ACC power source to an internal battery 34 and a DC-DC converter 32 during power supply from the ACC power source. The internal battery 34 is thus charged, and the DC-DC converter 32 supplies power converted in voltage to the drive recorder. When determining that the ACC power source is OFF, the charge/discharge control unit 31 exerts control such that the internal battery 34 is discharged and power is supplied from the internal battery 34 to the DC-DC converter 32. The monitoring battery 3 can thus continue power supply to the drive recorder even when power supply from the vehicle is interrupted.SELECTED DRAWING: Figure 2
