This section provides the information needed to construct an accurate thermally-coupled electrochemical model by outlining the activation energies and the reversible heat of the battery. This information is often not measured in parameterisations and is critical to predicting the internal temperature and its influence on thermal performance. The methodologies also describe the experimental and mathematical approach to quantify the parameter-dependencies of several electrochemical parameters, enabling the changes in performance during battery operation to be documented. The methods can be applied similarly to the widely-used materials, graphite and NMC.
