Online Multi Chemistry SoC Estimation Technique Using Data Driven Battery Model Parameter Estimation [PDF]

World Electric Vehicle Journal, 2018
Kalman filters have shown to be a very accurate and robust method for State of Charge estimation. However, their performance depends heavily on the accuracy of the used battery model and its parameters. These battery model parameters have shown to vary with the State of Health, cell chemistry, temperature and load current.
