BATTERY MODULE AND INSULATING PLATE

The present application relates to the field of energy storage devices, and in particular to a battery module and an insulating plate. 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; the tab includes a connecting segment and a bending segment; and the bus bar is fixed at one side of the insulating plate away from the battery group. 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. The plate assembly includes a guiding groove, each connecting segment passes through the guiding groove, and the bending segment and the bus bar are fixed and connected. In the battery module according to the application, the guiding groove can adjust the altitude of the tab as it passes through the insulating plate, facilitating the passage of the tab. After the tab are bent, the bending segment can be connected to the bus bar, then the process requirements can be met with no need to reserve a large space between the battery group and the insulating plate, which improves the energy density of the battery module.
