Based on previous numerical models of spirally-wounded lithium-ion cells and the coordinate transformation method, a new method to carry out real-time calculation and simulation to predict the temperature distribution within the cell is developed. Based on the coupling of heat equation and a pseudo two dimensional (P2D) physics-based electrochemical model, samples of input combinations covering the input space are collected as training data. Computer experiments to predict current source density and thus heat generation rate in the cell with Gaussian process are done to exam the validity of the method.
