  • Publication number: 20240120733
    Abstract: A cutoff control apparatus controls a cutoff unit in a vehicle-mounted system which includes: a power storage unit; a power line between the power storage unit and a load; and the cutoff unit that switches between a cutoff state that cuts off supplying of power on the power line from the power storage unit side to the load side and a canceled state where the cutoff state is canceled. In the vehicle-mounted system, the cutoff unit includes a first cutoff unit and a second cutoff unit, and the second cutoff unit enters the cutoff state when a first overcurrent state has occurred on the power line with the first cutoff unit in the canceled state. The cutoff control apparatus includes a control apparatus that instructs the first cutoff unit to switch to the cutoff state when the power line is in a second overcurrent state.
