Abstract: The application relates to the technical field of energy storage devices, and in particular, to a device, a battery pack, a battery module, and a connection assembly. The connection assembly includes: a connecting sheet; an insulating film which is connected to a plurality of the connecting sheets, where the insulating film is provided with a weakened portion. In the present application, the weakened portion has weaker strength. When force is applied, deformation and/or breakage occur/occurs at the weakened portion, thereby reducing the risk of tearing at other positions of the insulating film, improving the flexibility of the connection assembly, and reducing the risk of exposure of the connecting sheet due to the tearing of the insulating film, such that the risk of short circuit between the connecting sheet and other conductive component is reduced, and the safety performance of the battery module is improved.

Abstract: A battery sampling assembly, a cell fixing rack, a battery module, and an electric apparatus are provided. The battery sampling assembly includes a first sampling plate and a second sampling plate. A surface of the first sampling plate is provided with at least one first conductive sheet at one end and a second conductive sheet at another end, and a surface of the second sampling plate is provided with at least one third conductive sheet. In this application, the two sampling plates are separately provided with the conductive sheets, and the conductive sheets are directly welded to the surfaces of the sampling plates. Such design reduces space occupancy and allows for replacement for both wiring harness isolation and sampling wiring harnesses, so that relatively less components are used, and thus the volume of the entire module is reduced, and volumetric energy density of the battery module is increased.
