The majority of work carried out around battery models is partly motivated by vehicle simulation. Specifically, for electric vehicle simulation, some characteristics of the battery require more attention while others can be simplified, thus distinguishing dynamic models for battery system simulation slightly and requiring different tools. In this paper, we propose a dynamic battery model that accounts for changes in temperature and can be integrated in electric vehicle simulation for testing purposes by computer simulation. Possibilities shown open the door for extensions of the model according to the needs, using the bond graph formalism and Matlab/Simulink. Comparison with other literature data and experiment made on electric vehicle show the accuracy and the efficiency of this approach. (C) 2017 Hydrogen Energy Publications LLC.
