  "textContent": "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, 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 in the spraying pipeline is discharged from the opening. In the present application, after the first gas storage portion is provided, 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.",
