Electric vehicles (EVs) are increasingly recognized as a viable alternative to traditional internal combustion vehicles, offering cost savings and reduced carbon emissions. However, safety concerns regarding lithium-ion (Li-ion) batteries hinder widespread EV adoption. Understanding the behavior of these cells under extreme conditions is crucial due to their propensity for spontaneous reactions. Thermal runaway triggered by various abuse conditions such as thermal (overheating event), mechanical (nail penetration), and electrical (internal short-circuit event) poses significant risks. This study aims to employ several physics-based models—including the conjugate heat transfer model and thermal abuse model to assess the effect of overheating thermal abuse event on cell level. Through comprehensive simulation of this abuse event, the impact of parameters like heat transfer coefficients, oven temperature and calendar aging are studied. This thorough investigation yields valuable insights into Li-ion battery thermal response under an abuse scenario, aiding in the development of robust safety standards and effective thermal management strategies for advanced energy storage systems.
