BATTERY PACK WITH ENHANCED SAFETY AGAINST LEAKAGE OF LIQUID-PHASE REFRIGERANT

摘要

The present invention provides a battery pack comprising: at least one battery module containing a battery cell stack in which at least two chargeable and dischargeable battery cells are stacked; and a pack case surrounding the exterior of the battery module, wherein a liquid-phase refrigerant, isolated from the inner space of the pack case, removes heat conducted from the battery cells by cooling the pack case.
