Performance comparison of diffusion, circuit-based and kinetic battery models

Battery models are widely used in the development and operation of battery powered systems. Over the years, a variety of modelling methods have been proposed. In this paper, Circuit-based, Diffusion and Kinetic battery models for a Li-ion polymer battery are compared and the differences on the followed design philosophy are analysed. After the experimental extraction of the parameters, their performance is evaluated. This process is followed in order to choose the most suitable model for a real time application. Thus, apart from accuracy, the execution time in a specific hardware platform is also measured. For the parameterisation and verification of the models, a number of experiments are conducted. The results reveal which model is the best compromise between accuracy and computational effort and indicate the direction of future research to improve the overall performance.
