Abstract: The present disclosure relates to a battery module including at least one battery unit array structure, an upper cover, a lower cover and a fireproof component disposed vertically. Each battery unit array structure includes a plurality of battery units and a plurality of busbars electrically connected to the plurality of battery units. The battery unit array structure is disposed between the upper cover and the lower cover. Each battery unit of each battery unit array structure is provided with a vent facing towards the fireproof component. Different from the related art, when thermal runaway occurs in a battery unit according to the present disclosure, flame and high-temperature particles ejected from a vent of a battery unit are blocked by the fireproof component from burning adjacent battery units, thereby preventing the thermal runaway in the other battery units from being triggered by the existing thermal runaway.

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.
