Document Type and Number:
WIPO Patent Application WO/2018/181609
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a degradation estimating device, a degradation estimating method and a computer program with which it is possible for degradation of an electricity storage element to be estimated accurately. A degradation estimating device (101) is provided with: an acquiring unit (21) which acquires time-series data of the state of charge (SOC) of an electricity storage element; and an estimating unit (22) which estimates the degradation of the electricity storage element on the basis of the magnitude of variation of the SOC in the time-series data acquired by the acquiring unit (21). An electricity storage element degradation estimating method comprises: acquiring time-series data of the SOC of an electricity storage element; and estimating the degradation of the electricity storage element on the basis of the magnitude of variation of the SOC in the acquired time-series data.
