Abstract

This paper proposes real-time open circuit voltage (OCV) and capacity estimation algorithm without the initial state of the battery. The proposed algorithm estimates components of the equivalent circuit model (ECM) through the sum of square regression and obtains real-time OCV curve using the ECM voltage relationship and Coulomb counting method. The feasibility of the proposed algorithm has been demonstrated by simulation based on a lithium nickel manganese cobalt battery. Verification results show high accuracy of the OCV curve as the cycle repetition even though internal parameters of the battery are not provided.
