Apparatus And Method For Estimating Battery Parameter

Abstract: An apparatus for estimating a battery parameter according to an embodiment of the present invention comprises: an impedance measurement unit configured to output multiple alternating currents to a battery and measure multiple impedance values of the battery corresponding to the multiple alternating currents; and a control unit configured to fit the multiple impedance values to generate a first profile, correct the multiple impedance values on the basis of the first profile, determine multiple reference values on the basis of multiple corrected impedance values, fit the determined multiple reference values to generate a second profile, compare the second profile with the multiple corrected impedance values, and determine whether to configure a battery parameter according to the result of the comparison.
