An integrated SoC estimator is established based on the AEKF and PF. A cell model is established by integrating of the equivalent circuit model and electrochemical model. The RLS method is used for parameters identification to improve the model precision. Experiments are performed at different temperature and under dynamic current to verify the reliability and robustness.
