The fundamental mathematical equations for the battery model are presented in Eqs. (9), (10), where u k represents the system inputs (current, voltage, temperature, internal resistance, etc.) and n k+1 denotes the system output, which is the OCV.
The state equations of the battery are given in Eqs. (11), (12), where u b represents the voltage across the capacity C b, u 2 denotes the voltage across the circuit composed of R 2 //C 2, R 1 is the internal resistance, and U ocv represents the open-circuit voltage.
The primary limitation of this approach can be summarized as follows: Applicability to battery packs: While the model has been validated for a single cell, extending the proposed method to battery packs introduces challenges, such as managing inter-cell variations, thermal management, and balancing issues.
Data provided by the CALCE battery group highlight its suitability for the experiment. The chemistry components of the INR 18650-20R are a lithium–nickel–manganese–cobalt oxide (LiNiMnCo) cathode and a synthetic graphite anode [70, 71, 72, 73, 74, 75], and it is renowned for its robust stability and superior performance.
