Scale electro-thermal model of a lithium-ion battery for time-accelerated experiments in a hardware in the loop process

A scale electro-thermal model has been developed for LiFePO4/graphite lithium-ion battery. Such is appropriate in order to develop a physical emulation of battery the context hardware loop process, especially testing energy management strategies microgrids under same conditions (solar irradiation PV arrays, wind speed turbine, state health storage device) and potentially by compressing time. Classically, allows achieving laboratory size-scaled analysis but one major originality proposed approach deals with “time-compressed experimental analysis”. The based on extended modified shepherd coupled 1D thermal model. parameters are estimated through sequential characterization from several input profiles such as hybrid pulse power protocol open circuit voltage measurement. Both dimensional Vaschy-Buckingham theorem used obtain scaling factors (voltage, current, “but also” time) which applied original parameters. accuracy validated robustness (the current profile specific strategy typical microgrid application) voltage, time scaling. simulation results presented paper show that reduction horizon tests HIL process possible means an (scaling)
