In this work; the structure of a modular; acausal and reconfigurable electro-thermal battery model is described. The dynamic model structure adopted for the battery cell is based on an equivalent circuit whose parameters are generated using real cycling data through an optimisation algorithm. A linearised one-dimensional thermal mathematical model with lumped parameters is used to simulate temperature profiles for the cell. The cell and scaled-up pack model is parameterised for a number of commercially available cells ranging a number of cell formats; sizes and chemistries. These models are validated using highly transient and aggressive real-world as well as synthetic drive cycles.
