Abstract Most of the conventional batteries model for lithium-ion batteries dependent on theoretical and simplified mechanism model. Actually for lithium-ion batteries, because of unable to measure the process of the internal complex electrochemical reaction and vulnerable to the impact of external environment, the error is exist by theoretical model, and can not accurately reflect the dynamic characteristics of lithium-ion batteries. To solve this problem, according to ideal of data-driven, this paper uses a stochastic dynamic modeling method based on the EM algorithm and a lithium-ion battery discharge time series of stochastic dynamic model is proposed. Experimental results show that the use of this model to establish the proposed algorithm can effectively fit the experimental data, with good stability and robustness.
