Model Study of Lithium-Ion Battery Temperature Field

Using finite element analysis software -ANSYS, numerical simulation on temperature changes was done for the CA60 lithium-ion battery under different rate constant current charge and discharge status in this paper. The temperature distributions of every part of lithium-ion battery have been computed. And the data comparison of numerical simulation and actual measurement was carried out. The temperature changes in different part of the lithium-ion battery were analyzed. This study shows that the temperature distributions are significantly influenced by discharge time and thermal conductivities of component materials of lithium-ion battery. The research can provide the basis for the development of the thermal management system of lithium-ion battery.
