Patent abstract
Provided are a battery state estimation method and system and a recording medium for performing the method. The battery state estimation is provided by applying an ARX model and a dual extended Kalman filter. A battery state estimation system estimates a parameter of a battery model using an ARX model and estimates a battery state by applying the estimated parameter of the battery model to a 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.
