Abstract
(EN)
The present application provides a battery pack. The battery pack comprises: a box configured to have a cavity structure; an exhaust channel disclosed at the bottom of the box; a plurality of cells stacked and accommodated in the cavity structure of the box, the plurality of cells being located on the end surface of the exhaust channel away from the bottom of the box, and the end surface of each cell facing the exhaust channel being provided with an explosion-proof valve, wherein the structural layer of the exhaust channel facing the explosion-proof valve is provided with a weak zone, and when any cell is thermally out of control, the gas in the cell can be collected into the exhaust channel by the weak zone and discharged.
