Title:
ESTIMATION DEVICE AND ESTIMATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/218184
Kind Code:
A1
Abstract:
The present invention provides an estimation device 50 that estimates the deterioration amount of a power storage element 31 and that is provided with a storage unit 73 and a computation processing unit 71. The power storage element 31 has a feature wherein the temporal transition of the deterioration amount has a first deterioration domain F1 indicating a first transition and a second deterioration domain F2 indicating a second transition. The storage unit 73 stores first computation data for computing the deterioration amount with respect to the first deterioration domain F1, and second computation data for computing the deterioration amount with respect to the second deterioration domain F2. The computation processing unit 71 performs determination processing (S110) for determining deterioration domains of the power storage element 31, and estimation processing (S140) for selecting computation data corresponding to the deterioration domains from the storage unit 73 and estimating the deterioration amount of the power storage element 31.
