Geometric Models The main cooling methods currently used in prismatic lithium-ion batteries are liquid cooling and FHPs. Liquid cooling can effectively control the maximum temperature of the battery module, while FHPs can effectively reduce the temperature difference of the battery due to its temperature uniformity.
However, their performance is significantly influenced by temperature. To address this, this paper established an electrochemical-thermal (ECT) coupled model for a prismatic LiFePO4 (LFP) battery and conducted experimental measurements of its thermal conductivity, specific heat, and adiabatic temperature rise.
