Abstract: The software-in-the-loop and hardware-in-the-loop tests of battery management system require to have a real-time compatible electro-thermal battery pack model. In our study, a numerically complex electrochemical-thermal model has been characterized from experimental data of a nickel-rich, silicongraphite 18650-type lithium-ion cell. While it represents accurately the electro-thermal battery behavior, it’s hardly suitable for real-time application due to its intensively numerical solving effort and related calculation time if no huge numerical efforts are applied to reduce the model. The objective of this paper is to present a simple method to derive a reduced order electro-thermal cell model from the complex electrochemicalthermal cell model and build a real-time compatible battery pack model with the reduced order cell model.
