RELIABILITY ASSESSMENT OF BATTERY SYSTEMS USED IN AIRCRAFT PROPULSION SYSTEMS
Abstract
Safety and reliability of the energy storage devices as one of the most important components of Electric Aircraft and Hybrid Electric Aircraft is essential. Therefore, reliability evaluation of batteries is crucial for Electric Propulsion System design architecture. Li-ion battery reliability assessment is defined as calculating the faults or degradation occurrence probability and its impact on the obtainable capacity and power. Although failures of Li-ion battery cells involve both failures that cause safety issues (fire and explosion) and failures that reduce the ideal performance of the battery against the design intent, the focus of this study is on failures that lead to battery degradation. To estimate Electric Propulsion System reliability, it is critical to recognize the link between aging effects and battery performance. In this study, the lithium-ion battery systems to be used in aircraft were analyzed in terms of system, component and functional reliability from the aircraft design stages. In this study, reliability analysis of battery systems used in electric propulsion systems was performed, analysis results and current standards for certification were compared, and legal gaps in front of the industry's widespread and reliable use of electric propulsion systems were pointed out.
