POWER SOURCE SYSTEM, POWER SUPPLY CONTROL METHOD FOR THE POWER SOURCE SYSTEM, POWER SUPPLY CONTROL PROGRAM FOR THE POWER SOURCE SYSTEM, AND COMPUTER-READABLE RECORDING MEDIUM WITH RECORDED POWER SUPPLY CONTROL PROGRAM

摘要

Provided is a power source system for increasing the power supply force of an accumulating device, when a power source device stops, thereby to continue the supply of an electric power needed by a load device. A control unit includes a state quantity setting unit for setting such a first target state quantity indicating the charge state of the accumulating device, as to be used as a target value at the time of controlling the charge and discharge of the accumulating device. When the power source device stops, the state quantity setting unit changes the first target state quantity to a second target state quantity to be used as a target value exceeding the first target state quantity, so that the target state quantity of the accumulating device can be raised. At the stopping time of the power source device, therefore, the charge/discharge of the accumulating device is controlled on the basis of a target state quantity exceeding that at the action time of the power source device, so that the charged state of the charging device can be improved better than that at the action time of the power source device. As a result, the power supply force of the accumulating device can be augmented to continue the feed of the electric power needed by the load device, in place of the power source device.
