  "textContent": "Provided are 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, if thermal runaway occurs in a unit battery and a heat flow is discharged from the explosion-proof valve thereof, and the spraying pipeline can be heated at the explosion-proof valve under the action of the heat flow, to form an opening, such that the fire-fighting fluid is discharged from the opening. 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.",
