Control device

A power supply system comprising:

• a power supply module including a power supply device and a power storage device;
• and
• a control device including a control unit that when controlling power supply from the power supply module to an information processing device, in addition to supplying power from the power supply device to the information processing device, performs control to assist power used by the information processing device through power supply from the power storage device, wherein
• the control device includes a detection unit that detects power consumption of the information processing device and a stored amount of power in the power storage device, and
• the control unit included in the control device controls a value representing a characteristic of an amount of power supplied from the power supply device not to exceed a preset power supply device upper limit value, and sets a new power supply device upper limit value based on the power consumption detected by the detection unit;
• and wherein
• the control unit calculates a record charge and discharge amount representing a record of a past charge and discharge amount of power with respect to the power storage device based on past power consumption detected by the detection unit, and if the stored amount of power is not more than the threshold, the control unit corrects the record charge and discharge amount, and sets the new power supply device upper limit value based on the corrected record charge and discharge amount.

A non-transitory computer-readable storage medium storing a program comprising instructions for causing a control device to perform a method for controlling power supply from a power supply device and a power storage device to an information processing device, the method comprising:

• in addition to supplying power from the power supply device to the information processing device, performing a control to assist power used by the information processing device through power supply from the power storage device:
• detecting power consumption of the information processing device and a stored amount of power in the power storage device;
• controlling a value representing a characteristic of an amount of power supplied from the power supply device not to exceed a preset power supply device upper limit value;
• setting a new power supply device upper limit value based on the power consumption detected;
• and
• calculating a record charge and discharge amount representing a record of a past charge and discharge amount of power with respect to the power storage device based on past detected power consumption, and if the stored amount of power is not more than the threshold, correcting the record charge and discharge amount, and setting the new power supply device upper limit value based on the corrected record charge and discharge amount.
