Title:
VEHICULAR POWER SUPPLY CONTROL DEVICE AND VEHICULAR POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/153112
Kind Code:
A1
Abstract:
Provided is a technology that can drive a target load even when the remaining charge amount of a power storage unit is small, and that can efficiently drive the target load when the remaining charge amount of the power storage unit is large. This vehicular power supply control device (3) comprises: a discharge circuit (20) that includes a discharge path (22) and a switch (24); a voltage conversion circuit (30); and a control circuit (10) that controls the discharge circuit (20) and the voltage conversion circuit (30). In a failure state, the control circuit (10) controls the switch 24 to be in an ON state when an output voltage of a power storage unit (92) is equal to or greater than a threshold voltage Vth, and causes the voltage conversion circuit (30) to perform a voltage conversion operation when the output voltage of the power storage unit (92) is smaller than the threshold voltage Vth.
