Title:
CONTROL DEVICE OF ON-VEHICLE POWER SUPPLY SYSTEM
Document Type and Number:
Japanese Patent JP2020120560
Kind Code:
A
Abstract:
To appropriately raise a temperature of an on-vehicle battery while reducing a power loss.SOLUTION: An on-vehicle power supply system includes: a high-voltage battery 11 to be charged/discharged; and a high-voltage auxiliary machine 14 to be driven by power supply from the high-voltage battery 11. An ECU 20 controls power supply from the high-voltage battery 11 to the high-voltage auxiliary machine 14. The ECU 20 includes: a low temperature determination section for determining that the high-voltage battery 11 is in a predetermined low temperature state; and a power control section for increasing a battery output current to be output from the high-voltage battery 11 by power supply from the high-voltage battery 11 to a low-voltage auxiliary machine 18 when it is determined that the high-voltage battery 11 is in a low temperature state.SELECTED DRAWING: Figure 1
