Three-dimensional thermal modelling A three-dimensional thermal model based on the heat generation models of a battery body and posts is applied to predict the temperature distribution of a 25-Ah pouch lithium-ion battery (LGC-HEV-ES-HD-HCE01). The accuracy of the model in relation to variations in battery temperature, current, and SOC is studied.
A wide range of temperatures (from 263.15 K to 323.15 K), SOCs (from 0.1 to 1) and currents (from 0.5 C to 4 C) were applied in the experiment to ensure that the resistance-based heat generation model could adapt to the battery’s working range.
