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.
