  • Apparatus and method for managing a battery based on degradation determination
    Patent number: 11527900
    Abstract: An apparatus and a method for managing a battery are based upon degradation determination of the battery. The method includes determining a charging method when starting charging of a battery, storing at least one of a charge voltage, charge current, and temperature when starting charging of the battery, and when the determined charging method is constant current (CC) charging, determining a state of health (SOH) of the battery by comparing an increase in charge capacity of the battery with respect to an increase in charge voltage of the battery with a CC-section SOH mapping table, or when the determined charging method is constant voltage (CV) charging, determining the SOH of the battery by comparing at least one of an increase in the charge capacity of the battery and a charge time of the battery with a CV-section SOH mapping table.
