Title:
POWER STORAGE ELEMENT STATE ESTIMATION DEVICE AND POWER STORAGE ELEMENT STATE ESTIMATION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/092811
Kind Code:
A1
Abstract:
A power storage element state estimation device (100) for estimating the state of a power storage element (200) at a prescribed point in time, the power storage element state estimation device (100) being provided with a history acquisition unit (110) for acquiring the charging/discharging history of the power storage element (200) until the prescribed point in time, a degradation value estimation unit (130) for estimating a temporal degradation value and energization degradation value for the power storage element (200) at the prescribed point in time using temporal degradation information and energization degradation information corresponding to the charging/discharging history, and a state estimation unit (140) for estimating the state of the power storage element (200) at the prescribed point in time using the temporal degradation value and energization degradation value.
