Abstract

It is impossible to measure states of the battery such as remaining battery level (State of Charge : SOC) and degradation level (State of Health : SOH) directly. So, it is necessary to estimate SOC and SOH from measurable current and voltage. In this study, an equivalent circuit of a lithium-ion secondary battery is constructed and their parameters are estimated.
