    摘要： A battery management system to set an OCV setting of a battery, and a driving method thereof. The battery management system includes a sensing unit and a main control unit (MCU). The sensing unit measures a voltage of a battery. The MCU controls charging/discharging of the voltage of the battery, generates charge/discharge pulse pattern waveforms, measures and stores maximum and minimum voltages value of at least one pulse pattern among the charge/discharge pulse pattern waveforms, and sets an average of the measured voltage to an OCV setting from which an SOC is determined. The battery management system estimates the SOC while a vehicle is operating.

    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.

    摘要： A battery management system includes a sensing unit, a controller, an Open Circuit Voltage (OCV) calculator, and a State of Charge (SOC) determination unit. The sensing unit measures a total voltage of the secondary battery. The controller maintains the secondary battery in an open circuit state for a first period of time after a power supply switch is turned on, and couples the secondary battery to an external device when the first period of time ends. The OCV calculator receives the measured voltage from the sensing unit and calculates an OCV of the secondary battery during the first period of time. The SOC determination unit receives the calculated OCV from the OCV calculator and determines an SOC corresponding to the OCV.
