  "textContent": "A battery management apparatus includes an interface configured to acquire battery data of a management target battery measured at multiple degradation points, and a controller. The controller is configured to: generate a first state of charge-open circuit voltage (SOC-OCV) profile at a beginning-of-life (BOL) point and voltage-capacity profiles of the management target battery at the multiple degradation points, based on the battery data; identify a boundary voltage that distinguishes an upper voltage degradation characteristic with an upper capacity degradation rate and a lower voltage degradation characteristic with a lower capacity degradation rate, based on the voltage-capacity profiles; and estimating a second SOC-OCV profile at a middle-of-life (MOL) point, based on the upper capacity degradation rate, the lower capacity degradation rate, and the first SOC-OCV profile.",
