With the rapid increase in electric vehicle penetration, fires are increasing every year. So far, the results of electric vehicle fire investigation have reached the limit of direct evidence in the face of the disappearance of tangible evidence due to thermal runaway of the large lithium-ion battery pack, an essential component of electric vehicles. In this study, we identified commonalities in various electric vehicle fire investigation cases along with a clear understanding of electric vehicles. If direct evidence cannot be prevented from being destroyed due to thermal runaway of the lithium-ion battery, The indirect evidence will remain in the vehicle's BMU(Battery Management Unit) just before the fire. By utilizing indirect evidence, such as available battery voltage information, to reduce the scope of inspection in large lithium-ion battery packs and to conduct diverse and precise inspections on direct evidence within a limited range, we suggest an efficient direction for electric vehicle fire investigation in the future(Oman, H. 2002).
