Abstract-A computationally efficient reduced-order electrochemical-thermal model for small-format cylindrical lithium ion cells is developed, by applying the Padé approximation technique to the Pseudo-2-Dimensional battery model. Whence the amount of the total heat produced in the battery is obtained which in turn allows the evolution of the cell temperature is computed based on a simplified thermal model. The proposed model is computationally efficient whilst its accuracy compares favorably with those obtained using the 1dimensional radial electrochemical-thermodynamic model implemented in Comsol Multiphysics.
