1. A power source system, comprising:
- a power unit for supplying power to a load device;
a power accumulator for supplying the power to the load device in place of the power unit when the power unit is stopped; and
a controller for controlling the power supply from the power accumulator to the load device,wherein the controller sets an operable voltage, which is determined as an output voltage for ending discharge of the power accumulator, at a first voltage when the power unit is operated, and sets the operable voltage at a second voltage lower than the first voltage when the power unit is stopped, thereby increasing the power supplied to the load device by the power accumulator.

Abstract
A power source system capable of temporarily increasing the power supply capacity of a power accumulator when an interruptible power source is stopped. Upon receiving stop information of the interruptible power source from an integrated control ECU, a controller reduces an operable voltage that is determined as an output voltage for ending discharge of the power accumulator, outputs the reduced operable voltage from a communication part to the integrated control ECU. The integrated control ECU controls a charge/discharge control device based on the reduced operable voltage, and increases the power supply capacity of the power accumulator.

6. A power supply control method of a power source system having a power accumulator for supplying power to a load device in place of a power unit when the power unit supplying power to the load device is stopped, the power supply control method comprising the steps of:
-
setting an operable voltage, which is determined as an output voltage for ending discharge of the power accumulator, at a first voltage when the power unit is operated; and setting the operable voltage at a second voltage lower than the first voltage when the power unit is stopped, thereby increasing the power supplied to the load device by the power accumulator.

7. A power supply control program of a power source system having a power accumulator for supplying power to a load device in place of a power unit when the power unit supplying power to the load device is stopped, the power supply control program causing a computer to function as:
-
a stop determination part for determining the presence/absence of stoppage of the power unit; and a voltage setting part for setting an operable voltage, which is determined as an output voltage for ending discharge of the power accumulator, at a first voltage when the power unit is operated, and setting the operable voltage at a second voltage lower than the first voltage when the power unit is stopped, thereby increasing the power supplied to the load device by the power accumulator.

8. A computer readable recording medium, which has recorded thereon a power supply control program of a power source system having a power accumulator for supplying power to a load device in place of a power unit when the power unit supplying power to the load device is stopped,
wherein the power supply control program causes a computer to function as: -
a stop determination part for determining the presence/absence of stoppage of the power unit; and a voltage setting part for setting an operable voltage, which is determined as an output voltage for ending discharge of the power accumulator, at a first voltage when the power unit is operated, and setting the operable voltage at a second voltage lower than the first voltage when the power unit is stopped, thereby increasing the power supplied to the load device by the power accumulator.
