Title:
PARAMETER ESTIMATION DEVICE, PARAMETER ESTIMATION METHOD, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/230033
Kind Code:
A1
Abstract:
A parameter estimation device for estimating parameters for an equivalent circuit model for a secondary battery comprises a voltage acquisition unit for acquiring a time series of voltages of the secondary battery, a current acquisition unit for acquiring a time series of charge/discharge currents of the secondary battery, an estimation unit for estimating the parameters on the basis of the voltages acquired by the voltage acquisition unit and the charge/discharge currents acquired by the current acquisition unit, and a prohibition unit for prohibiting the estimation of the parameters by the estimation unit on the basis of the charge/discharge currents acquired by the current acquisition unit or the voltages acquired by the voltage acquisition unit.
