Abstract: The present application provides a battery pack and a spraying system thereof. The spraying system comprises: a spraying pipeline configured to circulate a fire-fighting fluid circulation, the spraying pipeline being capable of forming an opening after being heated; and a first gas storage portion configured to store a compressed gas, where the compressed gas in the first gas storage portion is capable of driving the fire-fighting fluid in the spraying pipeline to be discharged under the action of gas pressure. In the present application, the gas pressure of the compressed gas in the first gas storage portion can provide the power for discharging the fire-fighting fluid from the opening of the spraying pipeline, such that the fire-fighting fluid can be continuously discharged from the spraying pipeline, and there is a large flow rate in the discharging process, so as to ensure that the spraying system has a good spraying effect.

Abstract: The present disclosure provides a spray system for a battery pack and a battery pack. The spray system includes a spray pipeline configured to circulate a spray liquid and form an opening when being heating, a liquid storage device communicating with the spray pipeline, and a driving device including a driving component and an elastic component connected to the driving component. The driving component, under an elastic force applied by the elastic component, drives the spray liquid in the liquid storage device to flow into the spray pipeline. In the present spray system, the spray liquid not only in the spray pipeline but in the liquid storage device can be discharged to spray, thereby improving the spray effect, preventing the heat flow generated when the one battery unit is thermally out of control from spreading to the adjacent battery units, and improving the safety of the battery pack.
