Abstract

A dynamic model for Li-ion batteries based on an equivalent switched electrical circuit is proposed. The switching topology of the model allows one to discriminate the model parameters for charging, discharging and relaxation phases. Thermal effects and the reversible entropic heat are taken into account, too. The proposed model is shown to require a lower number of parameters to be identified with respect to the classical equivalent circuit battery model. An identification procedure for determining the electrical and thermal model parameters is defined and its effectiveness is verified through experimental results.
