Title:
VEHICULAR BACKUP POWER SUPPLY CONTROL DEVICE AND VEHICULAR BACKUP POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/027238
Kind Code:
A1
Abstract:
The purpose of the present invention is to effectively suppress an increase in the capacity of a power storage unit. This vehicular power supply control device (1) is provided with a discharge unit (3B), a control unit (5), and a temperature acquisition unit (5A). The control unit (5) controls a discharge operation so that the output voltage from the discharge unit (3B) reaches a target voltage. The temperature acquisition unit (5A) acquires the temperature of a power storage unit (7). The control unit (5) sets the target voltage to a first target voltage when the temperature acquired by the temperature acquisition unit (5A) is within a predetermined first temperature range, and sets the target voltage to a second target voltage higher than the first target voltage when the temperature acquired by the temperature acquisition unit (5A) is within a predetermined second temperature range higher than the first temperature range.
