The continuous growth of electric vehicles (EVs) has led to a significant increase in the production of lithium-ion batteries, which are essential for powering electric vehicles. To meet the rising demand for EVs and ensure the efficiency of battery testing facilities, this thesis focuses on the discharge process of tested cells and its acceleration by applying air-cooling. Safety and Environment Testing facility plays a critical role in evaluating and ensuring the safety and environmental impact of lithium-ion batteries prior to their integration into electric vehicles. The discharge process is a crucial component of a battery’s post-testing and pre-recycling. By implementing air cooling during the discharge process, it allows for a faster discharge process which saves time and ensures an efficient process. This research evaluates a discharge system which incorporates air cooling in the discharge process of tested cells. The study investigates the ability of the system to use a high discharge current to reduce the discharge time in the Safety and Environment testing facility. To achieve these objectives, this research employs a combination of literature study and Computational Fluid Dynamics (CFD) simulations for reliable thermal modeling. The thesis deals with an existing discharge system which is evaluated for 0.5C and 1C discharge rates under natural and forced air cooling while setting the maximum cell temperature at 45°C. The results show that 0.5C discharge rate under both natural and forced air cooling fulfills the maximum temperature requirement, while the temperature exceeds the limit for 1C discharge rate under both natural and forced convection modes. Achieving a 0.5C discharge rate would be beneficial for the testing facility as it would accelerate the discharge process compared to the existing discharge method.
