Some embodiments of the present application relate to a battery module and a battery pack. The battery module includes a plurality of battery cells, two insulating members and a binding strip. The insulating member includes a first face and a second face, the first face is located on a side face of the battery module, the second face is located on a bottom face of the battery module, and the two insulating members are respectively disposed on two sides of the battery module in a horizontal direction. The binding strip surrounds the plurality of battery cells and the insulating members.

Battery module and battery pack

The present application provides a battery module, which includes a plurality of batteries, an end plate and an output electrode connecting sheet. The plurality of batteries are arranged in a longitudinal direction. The end plate has: a main body portion, located on one side of the plurality of batteries in the longitudinal direction; and an extension portion, formed on the main body portion and extending in the longitudinal direction away from the batteries. The output electrode connecting sheet has: a first connecting portion, connected to a corresponding battery; and a second connecting portion, connected to one end of the first connecting portion and fixed to the extension portion of the end plate.

Battery module

The present application relates to a battery module and a battery pack, the battery module including a battery cell arrangement structure, bus bars and a fixing plate, where the battery cell arrangement structure includes a plurality of battery cells; the plurality of battery cells are electrically connected by means of a plurality of the bus bars to form a first output electrode of the battery module and a second output electrode of the battery module, and the first output electrode of the battery module and the second output electrode of the battery module are arranged at a same end of the battery module along a horizontal direction; the fixing plate is provided with an insulating portion, and at least a part of the insulating portion is located between the first output electrode of the battery module and the second output electrode of the battery module.

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.

Battery module with fireproof and fire-extinguishing components

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.

A battery module includes: a box having an inner cavity; at least two battery unit array structures, each of the at least two battery unit array structures including a plurality of battery units arranged along a length direction; and at least two support components, each of the at least two support components being fixed to a side of one of the at least two battery unit array structures in a height direction. The at least two battery unit array structures are arranged along a width direction and correspond to the at least two support components in one-to-one correspondence. The battery unit array structures and the components are disposed in the inner cavity.

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.
