Abstract

Disclosed are an apparatus and a method of generating a lithium iron phosphate (LiFePO₄, LFP) battery model. The apparatus includes: a lithium state recorder configured to record a state of lithium (Li) in a positive electrode active material of an LFP battery according to charging or discharging of the LFP battery; and a battery model generator configured to generate a battery model of the LFP battery based on the recorded state of the Li in the positive electrode active material. The battery model generator may generate the battery model by modeling the LFP battery through adding an additional voltage increment corresponding to a charging or discharging path of the LFP battery to an open circuit voltage (OCV), in consideration of the state of the Li in the positive electrode active material.
