This study experimentally compares and investigates the influencing factors on the TR characteristics of LIBs induced by dual heat sources. It explores both internal battery conditions (cathode material, SOC) and external heat source conditions (arrangement mode of dual heat sources, heating power).
Internal battery factors are found to be the primary determinants of the severity of LIB TR, while external heat sources play a crucial role in determining battery reliability and the urgency of measures to be taken in abnormal situations. 1. Both internal and external heat source conditions influence TR behavior.
