Scaling electro-thermal model of a lithium-ion battery for time-accelerated experiments in a HIL system

Résumé

This paper describes a scaled-size electro-thermal model of a Lithium-ion (Li-ion) battery. This model is used in order to develop a physical emulation of the scaled battery in a Hardware In the Loop (HIL) process. Physical emulation allows scaling the actual process but also accelerating HIL experiments through an innovative concept: the “compacted virtual time”. According to the management strategies implemented in the HIL process and to environmental conditions (temperature) of the battery, the electrical performance (energy/power) of the actual device and its physical emulator will be different. The electrical model is coupled with a 1D thermal model of a cell. The model parameters are determined from experimental data and by using a nonlinear least-squares solver. A robustness analysis, with voltage, current and time scaling is presented in order to determinate the accuracy of the scale model.
