Li-ion cell electro-thermal model based on Kalman filtering

The cell management is as much important as the cell charge method. In order to manage effectively cell, a good knowledge of cell behaviors is required. Behaviors - electrical and thermal - are captured by the cell model. Cell modeling is very common in literature, but parameters extraction is not precisely explained. This paper will deal at first with an electro-thermal model based on extended Kalman filtering (EKF), which can allow to extract parameters, and in a second time with a fast and accurate measurement procedure.
