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.
