Abstract
An estimation apparatus that estimates a degradation amount of an energy storage device includes: a storage unit; and an arithmetic processing unit. The energy storage device has a characteristic of including a first degradation area in which a temporal transition of a degradation amount shows a first transition and a second degradation area in which the temporal transition of the degradation amount shows a second transition. The storage unit holds first arithmetic data for calculating the degradation amount in the first degradation area, and second arithmetic data for calculating the degradation amount in the second degradation area. The arithmetic processing unit executes determination processing of determining a degradation area of the energy storage device, and estimation processing of selecting arithmetic data corresponding to the degradation area from the storage unit to estimate the degradation amount of the energy storage device.
