Abstract: The present application discloses a battery pack, comprising a first battery module, a second battery module, a housing and a fireproof member. The first battery module includes a plurality of battery cells which are provided with vents; the second battery module includes a plurality of battery cells which are provided with vents. Both the first battery module and the second battery module are arranged in the housing; the fireproof member is vertically disposed and located between the vents of the first battery module, where the vents of the first battery module and the vents of the second battery module both face the fireproof member. The battery pack prevents collective thermal runaway of the battery cells by using the fireproof member to separate the battery cells of the first battery modules and the battery cells of the second battery modules.

Abstract: 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.
