Lithium-ion batteries are the source of energy for many battery-powered devices due to their high energy density and specific energy. These batteries generate a significant amount of heat during charging and discharging. Therefore, managing the thermal behavior becomes more critical to avoid the overheating of these batteries. The purpose of this paper to investigate the thermal behavior of the Cramer 82V battery pack from Globe Group during high current discharge and provide a simulation model that can be the foundation for the next generation of batteries. The approach of this project was to research, test, and simulate the battery pack to understand and model the thermal behavior. For more extensive sampling, 7 Cramer 82V6Ah batteries were tested to investigate and analyze the thermal behavior of the batteries during the discharge. In addition, several thermal simulations in SolidWorks were conducted on the battery pack model and compared to the experimental results. The results from the simulation and experiment are compared at specific positions to ensure the simulation results are valid and can be used for the development of the next generation of the battery pack.
