Modeling of Electric Vehicle batteries using RBF neural networks

Electric Vehicles (EVs) are promised to significantly reduce the consumption of conventional fossil fuels in the transport sector as well as to limit the overwhelming greenhouse gas emissions. An accurate battery model is indispensable for the design of charging and discharging control of EVs. A new Radial Basis Function (RBF) modelling approach, which combines the Levenberg-Marquardt method to tune the non-linear parameters and an input selection approach for confining the number of input variables is proposed to model the batteries of EVs. Experimental results on modelling Li-ion batteries show that the resultant models have achieved high accuracy on training data and desirable generalization performance on unseen data.
