Abstract
A battery management system using a measurement model modeling a battery, and estimating a SOC (state-of-charge) of the battery, and a battery driving method thereof. The battery management system is constructed with a sensor, a predictor, a data rejection unit, and a measurement unit. The sensor senses a charging and discharging current flowing through the battery, a temperature of the battery, a terminal voltage of the battery. The predictor counts the charging and discharging current, and estimates the state-of-charge of the battery. The data rejection unit generates information associated with an error generated from the measurement model, as a function of at least one of the battery temperature, the charging and discharging current, the state-of-charge, and a dynamic of the charging and discharging current. The measurement unit corrects the estimated state-of-charge of the battery, using the measurement model and the information associated with the error.
