Title:
ON-VEHICLE POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/089787
Kind Code:
A1
Abstract:
An on-vehicle power supply device (10) is used for an on-vehicle power supply system (100). The on-vehicle power supply system (100) comprises a battery (20), an electric power path (21) to which electric power based on the battery (20) is to be supplied, and a capacitor (22) which is connected to the electric power path (21). The on-vehicle power supply device (10) comprises a mechanical system main relay (first SMR (51)), a parallel circuit (53), and a second relay (56). The system main relay (first SMR (51)) is provided to the electric power path (21) on the battery (20) side with respect to the capacitor (22). The parallel circuit (53) has a configuration in which a first relay (54) and a resistor part (55) are connected in series, and is provided in parallel to the system main relay (first SMR (51)). The second relay (56) is provided in parallel to the resistor part (55).
