Title:
ELECTRICAL JUNCTION BOX FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/071146
Kind Code:
A1
Abstract:
The purpose of the invention is to facilitate starting a vehicle when a low-voltage battery runs out of charge in the vehicle. The electrical junction box (10) is equipped with a special simple power supply (25). An internal circuit of the electrical junction box (10) supplies the output of the simple power supply (25) as the operating voltage of a DC/DC converter to activate the DC/DC converter when the low voltage battery runs out. When the DC/DC converter is activated, high-voltage power stored in a high-voltage battery on the vehicle can be stepped down and supplied to a circuit on the low-voltage battery side, thereby enabling normal starting operations such as starting the engine. An emergency start mode can be selected by a user's switch operation or by automatic detection of power supply voltage drop.
