Model Simplification of Lithium-Ion Battery Module Heating for Electric Cars

This paper aims to numerically examine the feasibility of simplifying the heating mechanism of a lithium-ion battery module using the lumped-system approach. Through this approach, the battery module is treated as a rectangular module that produces almost the same amount of heat compared to the battery module that contains 180 IHR 18650 battery cells, which generate heat individually. The mathematical model satisfies conservation laws of mass, momentum, and energy. The results show that by setting the appropriate heat generation rate for the rectangular module, it is absolutely possible for the lumped system model to produce similar temperature fields and heat fluxes without introducing too much discrepancy.
