Experimental study on a cooling system in abnormal heat emission of Lithium-ion Battery

Abstract

The purpose of this study is to maintain the performance of LiB (lithium-ion battery) of electric vehicle by controlling temperature of LiB. We verified the effectiveness of cooling system utilizing PCM (phase change material) and HP (heat pipe) at the time of sharp temperature rise of LiB as in abnormal heat emission. As a result, we found that cooling by PCM was more effective than cooling by HP at the time of sharp temperature rise of LiB.
