  • Publication number: 20230299440
    Abstract: A battery includes a plurality of battery cells arranged in a first direction. The battery cell includes a first wall and a second wall that intersect, the first wall is provided with a pressure relief mechanism, and a protective member is disposed between the second wall and an inner wall of a box. The pressure relief mechanism and the protective member are disposed on two different walls of the battery cell respectively. When emissions produced by thermal runaway of the battery are discharged from the pressure relief mechanism disposed on the first wall, if some emissions fall between the second wall of the battery cell and the inner wall of the box, under the protective effect of the protective member, electrical connection between the second wall of the battery cell and the inner wall of the box can be effectively avoided, thereby reducing the risk of short circuit.

  • Patent number: 11705605
    Abstract: The present application relates to a battery module. The battery module includes a battery group and an insulating plate. The battery group includes a bus bar and a plurality of battery units, each battery unit includes a tab which includes a connecting segment and a bending segment. The insulating plate includes a plurality of plate assemblies, and the adjacent plate assemblies are connected through a connecting plate. There is an obtuse angle between each plate assembly and the connecting plate connected thereto. Each connecting segment passes through a guiding groove, and the bending segment and the bus bar are fixed and connected. The guiding groove can adjust the altitude of the tab as it passes through the insulating plate. The bending segment can be connected to the bus bar, then the process requirements can be met with a small space, which improves the energy density of the battery module.
