POWER SUPPLY CONTROL APPARATUS

In a power supply control apparatus, a control unit is configured to execute: discharge control of turning off a first switch and turning on a second switch to discharge electric power from a backup power supply to a backup load; first charge control of turning on the first switch and turning off the second switch to charge the backup power supply via a charging DC/DC converter; and second charge control of turning on the first switch and turning on the second switch to charge the backup power supply via the second switch. In charging the backup power supply, the second charge control is executed only in a case in which a current value of a charging current is equal to or greater than a first predetermined value and equal to or less than a second predetermined value that is greater than the first predetermined value.
