    摘要: 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.

    摘要: A battery management system and a method of operating the same includes a plurality of battery cells constituting one pack and connected to a battery having at least one pack, and determines an estimated state of charge (SOC) of the battery. The battery management system determines whether or not a pack current flows, and controls a reset of an SOC depending on the determination result. The battery management system sets an OCV idle period associated with a temperature of the battery, and compares the idle period with a time for which the current of the battery does not flow, and sets the reset OCV depending on the comparison result. The battery management system resets the estimated SOC as the reset SOC associated with the reset OCV.
