Abstract
Coupled electro-thermal models are essential for the battery management system (BMS) to accurately predict the electrical and temperature dynamics of automotive batteries. Currently, an electrochemical model and a thermal model are developed and parametrised separately before being coupled together. A new procedure known as pulse-multisine (PM) has been developed that combines a multisine and a pulse signal, which allows for concurrent electrochemical and thermal parametrisation from the same experiements. A non-linear Equivalent Circuit Model and an analogous lumped parameter thermal model are parametrised and validated against automotive drive cycles. Despite the procedure requiring fewer experiments, the model has increased accuracy.
