(1) Adopting the Bernardi equation to calculate heat generation inside of the battery , , that demonstrates advantages of time-saving and high effectiveness, but ignores the detailed electrochemical process and assumes heat generation is uniform when in fact this assumption is found to not always be accurate.
It is evident that LIB heat generation is influenced by factors such as the initial and final state of charge, chemistry, construction, charge or discharge rate, and battery temperature. The literature review indicates a scarcity of studies on the influence of configurational parameters using battery calorimeters with computational fluid dynamics.
It is difficult for lithium-ions to diffuse to the particle surface and react with the electrolyte at subzero temperature. As a result, the SOC on the NE surface decreases rapidly, causing the deficiency of lithium-ions and increasing the resistance and thus the battery heat generation significantly.
Various parameters influence the heat generation of LIBs, with battery temperature being affected by factors such as cooling and heating systems in the thermal management system, ambient temperature, battery thermal conductivity, heat generation, and battery heat capacity.
The average heat generation rate over the discharge duration shows a quadratic polynomial relationship with discharge current and an inverse quadratic correlation with ambient temperature. The cycling process contributes to an increase in the heat generation rate, reflecting the aging phenomenon of the battery.
