Abstract
Lithiumion batteries are widely used in energy storage scenario because of their multiple privileges to improve the absorption ability of new energy systems. Electro-chemical parameters can describe the physical and chemical properties of battery internal component and material and provide abundant internal state information. The operating condition of energy storage lithium-ion battery is characterized of long continuous operating durations and random discharge process depending only on the load, which make the direct measurement of internal material and state change difficult to realize. In this paper, an indirect measurement method of lithium-ion battery elector-chemical parameters is proposed. A multi-step parameter initial value and identification interval determination schematic is proposed under the assistant of Bayesian Neural Network. Special current activation is also designed to satisfy the online application scenario. The proposed method is proved through simulation and realize highly efficient and accurate lithium-ion battery electrochemical parameter measurement.
