Title:
POWER-SUPPLY CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/089800
Kind Code:
A1
Abstract:
A power-supply control device (10) comprises a control unit (11) that controls a system main relay (first SMR (23)) and a pre-charge relay (25A). The control unit (11) starts first control of controlling the system main relay (first SMR (23)) to reach an OFF state and controlling the pre-charge relay (25A) to reach an ON state when a start condition for starting charge/discharge of a battery (20) is satisfied. The control unit (11) switches the first control to second control of controlling the system main relay (first SMR (23)) to reach an ON state and controlling the pre-charge relay (25A) to reach an OFF state when a pre-charge period has elapsed since the start of the first control. The control unit (11) sets, as the pre-charge period, a first period when a first condition is satisfied upon the establishment of the start condition or sets, as the pre-charge period, a second period longer than the first period when a second condition is satisfied upon the establishment of the start condition.
