A lumped-parameter thermal network model (LPTN) for a battery simplifies the complex thermal behavior of the battery by representing it as a network of interconnected thermal resistances and thermal capacitances. It's used to estimate battery temperature based on heat generation and heat transfer. The essential components of an LPTN model are thermal capacitances, thermal resistances, and heat sources. Thermal capacitance (C) represents the ability of a component or region of the battery to store thermal energy. Each 'lump' in the model is assigned a thermal capacitance value, which is determined by its mass and specific heat capacity. For example, the battery core, the battery case, and the cooling system can each be represented by a thermal capacitance. A higher thermal capacitance means the component can store more heat energy for a given temperature change. Thermal resistance (R) represents the resistance t....
