Multiphysical lithium-based battery pack modeling for simulation purposes

Hybrid and electric vehicle simulation requires battery models capable of predicting important macroscopic quantities such as state-of-charge, temperature and voltage. This paper presents a multiphysical battery pack model and describes the test procedure that must be followed to identify the different model parameters. Two high-energy density cells types have been modeled with this method and a comparison between measured and simulated values has been carried out. The model shows an error below than 3% compared to experimental results.
