摘要： 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.

摘要： A battery includes two battery cells arranged along a first direction and including two electrode terminals opposite to each other along the first direction. A first electrode of the two electrode terminals is disposed at an end of a first battery cell of the two battery cells along the first direction, and a second electrode of the two electrode terminals is disposed at an end of a second battery cell of the two battery cells along the first direction. Surface contact is formed between two end faces of the two electrode terminals, respectively. The two end faces are opposite to each other along the first direction. The two electrode terminals are configured to be fixedly connected to each other along an outer periphery of at least one of the two end faces to implement electrical connection between the two battery cells.

摘要： A battery, an electric apparatus, and a battery assembling method are provided. The battery includes: a plurality of battery cells; a strap-shaped member disposed fixedly relative to the plurality of battery cells; an electrical connection member located adjacent to the strap-shaped member; and a trough-shaped member, integrally having at least a first accommodation trough and a second accommodation trough, where the strap-shaped member is accommodated in the first accommodation trough, the connection member is accommodated in the second accommodation trough, and a portion of the trough-shaped member is located between the strap-shaped member and the battery cells. The trough-shaped member fastens the electrical connection member relative to the battery cells, avoiding fracture of the electrical connection member due to fatigue caused by high-strength loads. The electrical connection member can also be isolated from a wire harness and an ambient metal member, isolating and protecting the electrical connection member.
