Lithium-ion battery Thermal simulation discharge rate convection heat transfer

Abstract

A three-dimensional thermal model has been developed to examine the thermal behavior of a lithium-ion battery (LIB) during discharge. The effect of discharge rate and forced convection on the heat dissipation performance of models under different working conditions was analyzed. Simulation results show that with the battery discharge increasing from 3C to 7.5C, battery temperature increases from 307.12K to 338.86K, and the temperature difference of maximum and minimum is increases from 0.12K to 1.41K, respectively. Rather, with the convection heat transfer coefficient increasing from 5W/(m2•K) to 50W/(m2•K), the battery temperature reduces 21.78K. So increase discharge rate increases the battery temperature and reduces temperature distribution uniformity. Enhance convection heat transfer can greatly reduce the battery temperature, but it also decrease temperature distribution uniformity.
