The Bayesian algorithm is often used for parameter identification in electrochemical models. In , a Bayesian parameter identification framework for lithium-ion batteries was presented, wherein 15 parameters were identified within a pseudo-two-dimensional model.
The physics-based lithium-ion battery model used in this work to demonstrate the OED methodology is based on the work of Doyle, Fuller and Newman . However, the proposed optimal parametrization strategy is not limited to this specific model but instead widely applicable for electrochemical battery models and beyond.
The establishment of lithium-ion battery models is fundamental to the effective operation of battery management systems. The accuracy and efficiency of battery simulation models ensure precise parameter identification and state estimation.
Accurate estimation of the state-of-energy (SOE) in lithium-ion batteries is critical for optimal energy management and energy optimization in electric vehicles. However, the conventional recursive least squares (RLS) algorithm struggle to track changes in battery model parameters under dynamic conditions.
In addition, no comparison methods and discussions have existed in the above studies. The publications in Scopus are investigated between 2012 and 2022 with the item “battery parameter identification”. It is generally acknowledged that battery parameter identification is critical to state estimation and EV applications.
The estimation of each battery model parameter is made to lithium-ion battery with a capacity of 20 Ah, and the presented methodology can be easily adapted to any type of battery. The mean objective of the results is estimate the battery parameters to posteriorly use the battery model to estimate the SoC by adaptive method.
