Deterioration amount estimation device, energy storage system, deterioration amount estimation method, and computer program

A deterioration amount estimation device, comprising:

• a first calculation unit that calculates a calculated deterioration amount of an energy storage device;
• and
• a first estimation unit that estimates a transient deterioration amount based on a calculated deterioration amount at a calculation time point and a calculated deterioration amount at a predetermined time point.

A deterioration amount estimation device comprising:

• a calculation unit that calculates a deterioration amount of an energy storage device;
• and
• an estimation unit that estimates a continuous deterioration amount based on a deterioration amount calculated by the calculation unit at a time point when, in a case where a load of the energy storage device is smaller than a predetermined value, the deterioration amount decreases, and a reduction time in which a decrease amount converges has elapsed.

A deterioration amount estimation method, comprising:

• calculating a deterioration amount of an energy storage device;
• and
• estimating a transient deterioration amount based on a calculated deterioration amount and a continuous deterioration amount that does not decrease with time and continues.
