BATTERY STATE ESTIMATION METHOD USING DUAL EXTENDED KALMAN FILTER, SYSTEM THEREOF, AND RECORDING MEDIUM FOR PERFORMING SAME

摘要

Disclosed are a battery state estimation method, a system thereof, and a recording medium for performing the same. The method can estimate a state of a battery by applying an ARX model and a dual extended Kalman filter. The battery state estimation system estimates a parameter of a battery model by using the ARX model and estimates a state of the battery by applying the estimated parameter of the battery model to the dual extended Kalman filter including a state filter used to estimate a state of charge (SOC) and a weight filter used to estimate a state of health (SOH) of the battery model.;COPYRIGHT KIPO 2016
