Vehicle power control apparatus and vehicle power apparatus

A vehicle power control apparatus that controls a vehicle power system including a power unit that supplies power to a load, and a power storage unit that supplies power to the load via a load-side conductive path at least if power supply from the power unit enters a failed state, the vehicle power control apparatus comprising:

• a discharge circuit that includes a discharge path provided between the power storage unit and the load-side conductive path, and a switch provided on the discharge path, and is configured such that the load-side conductive path and the power storage unit are electrically connected via the discharge path when the switch enters an on state;
• a voltage conversion circuit that is provided between the power storage unit and the load-side conductive path, and is configured to perform at least a voltage conversion operation of converting a voltage of a power storage unit-side conductive path electrically connected to the power storage unit and applying a target voltage to the load-side conductive path;
• and
• a control circuit configured to control the discharge circuit and the voltage conversion circuit,
• wherein, during the failed state, if an output voltage of the power storage unit is greater than or equal to a threshold voltage, the control circuit performs control to bring the switch into the on state, and if the output voltage of the power storage unit is below the threshold voltage, the control circuit makes the voltage conversion circuit perform the voltage conversion operation.
