State output apparatus, state output method, and recording medium

A non-transitory computer-readable recording medium storing a state output program that causes a computer to execute a process, the process comprising:

• acquiring power storage device information including a voltage and a current of a power storage device;
• calculating an integrated current amount supplied to the power storage device during a period in which the voltage changes from a first voltage to a second voltage between a discharge end voltage and a charge end voltage by charging the power storage device;
• comparing the calculated integrated current amount with a reference integrated current amount stored in a storage device;
• and
• outputting a result of the comparison as information indicating a state of the power storage device.
