These models facilitate enhanced performance analysis and optimization in battery management applications. The state of power (SOP) of lithium-ion batteries is defined as the peak power absorbed or released by the battery over a specific time scale. This parameter has gained increasing importance as a key indicator of the battery’s state.
In , a Bayesian parameter identification framework for lithium-ion batteries was presented, wherein 15 parameters were identified within a pseudo-two-dimensional model. The validity of the identified parameters was confirmed through simulated voltage assessments, resulting in a relative error of less than 0.7% across varying discharge rates.
