Disclosed are an apparatus and a method for generating an LFP battery model. The apparatus for generating an LFP battery model according to the present disclosure includes a lithium state recording unit that records a state of lithium (Li) in a positive electrode active material of a lithium iron phosphate (LiFePO4, LFP) battery according to charging or discharging of the LFP battery; and a battery model generating unit that generates a battery model of the LFP battery based on the recorded state of lithium in the positive electrode active material, wherein the battery model generating unit may generate a battery model by modeling the LFP battery with multiple resistors and capacitors reflecting the state of lithium in the positive electrode active material.
