Learn MoreThere is a growing need to accurately and robustly model the performance of both individual cells and their aggregated behavior when integrated into battery packs. This paper presents a novel methodology for Lithium-ion (Li-ion) battery pack simulations under actual operating conditions of an electric mining vehicle.
The validated electrochemical-thermal models of Li-ion battery cells are scaled up into battery modules to emulate cell-to-cell variations within the battery pack while considering the random variability of battery cells, as well as electrical topology and thermal management of the pack.
In the same period, Mahamud et al. studied the thermal management of the Li-ion battery pack using a CFD tool. They also introduced a lumped-capacitance thermal model to evaluate the heat generated by each battery cell. Using this approach, they could investigate cell spacing and coolant flow rate parameters.
Therefore, different solutions can be investigated. One of the main issues analyzed in Simulation-Driven approaches is the thermal problem. The optimal temperature range for lithium-ion battery cells to operate is 25 to 40 °C, with a maximum temperature difference among battery cells of 5 °C .
This approach was one of the first studies that integrated one cell's thermal analysis into a complete battery pack study. The final scope of this research was to find a design approach to provide temperature uniformity in a battery pack with cylindrical cells. Li and Mazzola published an advanced battery pack model for automotive.
