Zusammenfassung:A battery parameter estimating apparatus according to an embodiment of the present disclosure includes an impedance measuring unit configured to output a plurality of AC currents to a battery and measure a plurality of impedance values for the battery to correspond to the plurality of AC currents; and a control unit configured to generate a first profile by fitting the plurality of impedance values, correct the plurality of impedance values based on the first profile, determine a plurality of criterion values based on the plurality of impedance correction values, generate a second profile by fitting the determined plurality of criterion values, compare the plurality of impedance correction values with the second profile, and determine whether or not to set a battery parameter according to the comparison result.
