A system for extinguishing a fire occurring in a high-voltage battery for a vehicle includes: a battery cell assembly in which a plurality of battery cells are stacked each other, an extinguishing-liquid tank inside which an extinguishing liquid is stored, an extinguishing-liquid supply line connecting the extinguishing-liquid tank and the inside of the battery cell assembly to each other, a coolant joining line branching off from a coolant line 25 through which a coolant circulates along the outside of the battery cell assembly and a radiator, the coolant being supplied to the inside of the battery cell assembly through the coolant joining line, and a control unit configured to perform control so that the extinguishing liquid and the coolant are supplied to the battery cell assembly through the extinguishing-liquid supply and coolant joining lines, when the control unit concludes that a fire occurs in the battery cell assembly.
