Thermal issues of lithium ion batteries are key factors affecting the safety, operational performance, life, and cost of the battery. An electrochemical–thermal coupling model based on thermoelectrochemical basic data was established to investigate the thermal behavior of LiFePO4 lithium ion battery. In this paper, the finite element method was used for simulation of temperature field distribution inside battery during charge–discharge process, and the influence of the charge–discharge rate and ambient temperature on the distribution of temp...
