Battery thermal management is critical for high-power battery packs commonly used in electric vehicles (EV) and hybrid electric vehicles (HEV). To design battery thermal management systems properly, obtaining accurate heat generation data from battery modules is essential. To measure heat generation from full-size, multiple-cell battery modules, we developed and tested a custom-made calorimeter...

Commercial coin cells with LiNi0.6Mn0.2Co0.2O2 positive electrode material were investigated using an accelerating rate calorimeter and a Tian-Calvet calorimeter. After cycling charging to the selected states of charge (SOCs), studied under thermal abuse conditions heat-wait-seek (HWS) method heating step 5 K threshold for self-heating detection 0.02 K/min. The onset temperature rise, i.e., run...
