Control device, control method, and recording medium

A control method comprising:

• estimating, based on a voltage value and a current value of a controlled device, an open circuit voltage (OCV) of the controlled device;
• calculating an integrated capacity of the controlled device based on the current value of the controlled device;
• and
• controlling discharging and charging of the controlled device, and calculating a full capacity of the controlled device based on:
• a first SOC and a second SOC that are remaining capacities (SOC) at a predetermined first OCV and a predetermined second OCV during the discharging or the charging of the controlled device;
• a first integrated capacity and a second integrated capacity that are integrated capacities at the first OCV and the second OCV during the discharging;
• and a third integrated capacity and a fourth integrated capacity that are integrated capacities at the second OCV and the first OCV during the charging.

A computer readable non-transitory recording medium embodying a program, the program causing a computer to perform a method, the method comprising:

• estimating, based on a voltage value and a current value of a controlled device, an open circuit voltage (OCV) of the controlled device;
• calculating an integrated capacity of the controlled device based on the current value of the controlled device;
• and
• controlling discharging and charging of the controlled device, and calculating a full capacity of the controlled device based on:
• a first SOC and a second SOC, which are remaining capacities (SOC) at a predetermined first OCV and a predetermined second OCV during the discharging or the charging of the controlled device;
• a first integrated capacity and a second integrated capacity, which are integrated capacities at the first OCV and the second OCV during the discharging;
• and a third integrated capacity and a fourth integrated capacity, which are integrated capacities at the second OCV and the first OCV during the charging.
