|Title:||CONTROL DEVICE FOR ONBOARD POWER SUPPLY SYSTEM, AND ONBOARD POWER SUPPLY SYSTEM|
A control device: that can be used in an onboard power supply system that uses a power storage unit to supply power at least when a power supply unit is down; and that makes it easy for the necessary power to be supplied from the power storage unit even if the power storage unit remains in use after it has been determined that the power storage unit is in a deteriorated state. A control device (2) that has: a control unit (11) that makes a charging circuit (3A) perform a charging operation such that the charge voltage of a power storage unit (92) reaches a target charge voltage; and a deterioration determination unit (13) that determines whether the power storage unit (92) is in a prescribed deteriorated state. The control unit (11): sets the target charge voltage at a first target voltage Vf when the deterioration determination unit (13) has determined that the power storage unit (92) is not in the deteriorated state: and sets the target charge voltage at a second target voltage Vg that is greater than the first target voltage Vf when it has been determined that the power storage unit (92) is in the deteriorated state.
