Real Time Soc Monitoring of a Li-Ion Battery

This article proposes the use of the Kalman filter applied to the determination of the state of charge of battery. We present in the first part the description of the Kalman filter and the identification of the parameters of the model. In the second part, the structure and the setting of the state of charge observer are represented. Then, the results of real-time experimental validations for different states of charge of the battery and different settings of the observer are presented.
