<p>A battery management system using a measurement model modeling a battery, and estimating a SOC (state of charge) of the battery, and a driving method thereof. The system includes 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 SOC 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 SOC, and a dynamic of the charging and discharging current. The measurement unit corrects the estimated SOC of the battery, using the measurement model and the information associated with the error.</p> |
