Title
(EN) Battery module and battery pack
Abstract
(EN)

The present disclosure discloses a battery module and a battery pack. The battery module comprises a plurality of battery cells and a fireproof member, wherein each of the plurality of battery cells is provided with a vent, and the vent faces the fireproof member; wherein the fireproof member includes a fireproof member body and a first extension connected to an upper end of the fireproof member; and/or a second extension connected to a lower end of the fireproof member. When thermal runaway occurs to the battery cells, flames and high temperature particles ejected out of the vent are blocked by the fireproof member body and the first extension and/or the second extension, thus preventing the ejected flames and high temperature particles from burning neighboring battery cells, and preventing the battery cells that has undergone thermal runaway from inducing thermal runaway of the neighboring battery cells opposite to the vents.
