  • Publication number: 20240372392
    Abstract: A battery management system determines a charging current to charge a battery pack in each period based on a derating factor of a charge cycle including a plurality of periods, updates the derating factor based on a result of comparing a voltage of the battery pack in each period with a voltage upper limit value set in the corresponding period, and uses the updated derating factor in a next charging cycle.

  • Publication number: 20240283273
    Abstract: A battery system may include: a battery pack including a plurality of battery cells; and a battery management system configured to derive a charging rate based on a charging target state of charge (SOC) for the battery pack and the temperature of the battery pack, and compensate for the charging rate through proportional-integral-derivative (PID) control based on an error voltage between any one of a plurality of cell voltages of the plurality of battery cells and an open circuit voltage (OCV) corresponding to the charging target SOC to generate a compensation charging rate.
