EXPERIMENTAL ANALYSIS OF PERFORMANCE OF LITHIUM ION BATTERY PACK DESIGNS BY SIMULATING INDIAN DRIVING CONDITIONS

摘要

Battery testing at the subsystem level or the component level is critical for the performance evaluation of an Electric Vehicle. Certain standards/test protocols have been formed to test the battery packs. However, the fidelity of the results obtained from those procedures is questionable. This research paper focuses on testing battery packs based on the real-time experimental data obtained from different vehicles to emulate exact Indian driving conditions. With multiple iterations, a standard battery pack testing protocol will be derived to validate the performance of different battery packs for Indian EVs. The validation process will also include an array of safety and functional checks which will be performed prior to the load cycle. In this research paper, the primarily focus on performance and life cycle of battery packs with cylindrical and prismatic cells. The design considerations and test results are also discussed.
