Abstract

In recent years, as a clean and efficient energy storage technology, lithium iron phosphate battery is widely used in large energy storage power stations, new energy vehicles and other fields. However, lithium-ion batteries still face obstacles that limit their application space. Once the temperature exceeds the working range of the battery, lithium iron phosphate battery will rapidly degrade, increasing the risk of facing fire and explosion and other safety problems. Multi-physical field full-coupling simulation is one of the important means to study the temperature of lithium iron phosphate battery operation process. Based on the electrochemical-thermal coupling full model of iron phosphate battery, this paper analyzes and studies the temperature change of battery operation process and obtains the temperature change of battery under adiabatic and actual conditions, which provides a basis for solving the thermal management problem of lithium iron phosphate battery operation process.
