BATTERY PACK AND BATTERY APPARATUS HAVING THE SAME

Abstract: a battery pack and a battery apparatus utilize cooling fluid and cooling fluid circuitry for cooling battery cells in a normal operating state in which an event is not detected and extinguishing the event in an abnormal state. the cooling fluid circuitry controls inflow and outflow rates of the cooling fluid, such as a fluid pump or a fluid valve connected to an inlet and an outlet of the battery pack. in a normal operating state in which an event, such as ignition, explosion, or gas emission of battery cells, is not detected, the operating heat resulting from charging and discharging of battery cells may be quickly cooled through immersion-type liquid cooling of the battery cells. in response to the detection of an event, the event may be quickly extinguished using the cooling fluid by raising the fluid level of the cooling fluid to a preset elevated level.
