Abstract: Disclosed is a battery state prediction device including a data measurement unit that measures information about a battery and to output first data and a battery state estimation unit that calculates a state of charge (SOC) value of the battery based on the first data, generates second data by pre-processing the first data based on the SOC value, and estimates a state of health (SOH) of the battery based on the second data. The battery state estimation unit calculates the SOC value based on an extended Kalman filter and adjusts a parameter of the extended Kalman filter based on the estimated SOH.

Abstract: An apparatus and a method for predicting a state of a battery are provided. The apparatus includes a data measuring unit that measures information about the battery and outputs first data, a data producing unit that reflects a change in available capacity of the battery based on at least a portion of the first data to calculate a corrected state of charge and processes the first data based on the corrected state of charge to generate second data, and outputs the second data, and a battery state estimating unit that estimates state information of the battery based on the second data.
