Summary:PURPOSE: An apparatus for evaluating battery features is provided to identify a circuit constant in the equivalent circuit model of battery, with an arbitrary current wave pattern, in consideration of Warburg impedance, with a high precision and to proceed a high precision of battery feature evaluation. CONSTITUTION: A current wave pattern partition section is composed to output an arbitrary wave pattern by partitioning it with a plurality of step functions in a plurality of micro time intervals. A circuit constant optimization module(6) is composed to compute a circuit constant of the optimized equivalent circuit model based on the step function, voltage experimental values and equivalent circuit model data.
