The method is of strong robustness against changes in ambient tempera-tures and convection conditions. Heat generation inside a battery cell regardless of sources are covered. Estimation of heat generation in lithium-ion batteries (LiBs) is critical for enhancing battery performance and safety.
The model is validated against the heat generation rate of a large format pouch type lithium-ion battery measured by a developed calorimeter that enables the measurement of heat generation rate and entropy coefficient. The model is seen to be in good agreement with the measured heat generation rates up to 3C from −30 °C to 45 °C.
A classi cation scheme for the heat generation processes fi inside lithium-ion batteries and classi cation of heat fi generation of lithium-ion batteries including classication fi of battery thermal analysis is demonstrated in Figure 3.
The model is implemented in COMSOL and validated against experimental data. Results show <5 % error in predicted heat generation and temperature profiles. Accurate thermal modeling is essential for predicting the behavior and ensuring the safety of lithium-ion battery cells and modules.
