An apparatus for estimating a battery degradation state, a system including the same, and a method thereof are provided. The battery degradation state estimation system includes a battery degradation state estimation apparatus, implemented by a processor, that estimates a battery degradation state by using a correction coefficient calculated from a difference between a first open circuit voltage (OCV), calculated from battery state information, and a second open circuit voltage (OCV_i), acquired based on a change amount of a battery state of charge (SoC) determined by current integration, and a memory device that stores the first open circuit voltage (OCV), the second open circuit voltage (OCV_i), and the correction coefficient.
