Title:
VEHICLE BACKUP DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/014099
Kind Code:
A1
Abstract:
The present invention provides a configuration that allows the charging voltage of an auxiliary power supply to be set to reflect the temperature state during the vehicle stop period. A vehicle backup device (1) comprises a charge/discharge circuit (3), a temperature detection unit (50), and a control unit (5). The control unit (5) causes the charge/discharge circuit (3) to operate to set the charge voltage of an auxiliary power supply (92) to a target voltage on condition that a start switch (70) for the vehicle is turned on. The control unit (5) sets the target voltage on the basis of the temperature detected by the temperature detection unit (50) when the start switch (70) is in the off state.
