Abstract

The embodiment of the invention provides a sampling assembly and a battery module. The sampling assembly is used for the battery module, and comprises a bus bar, a circuit board and a connection sheet; the bus bar has a first surface and a second surface, which are opposite; the bus bar comprises an installation groove, which is formed by extending along the direction from the first surface to thesecond surface; the circuit board is arranged at one side of the bus bar; the connection sheet comprises a first flat plate part and a bending part, which are connected mutually; one end of the firstflat plate part is connected with the bus bar; the other end of the first flat plate part is connected with the circuit board; and the bending part is positioned in the installation groove. In the embodiment of the invention, because the bending part is positioned in the installation groove, the connection sheet can be hooked with the bus bar through the installation groove; furthermore, connection between the connection sheet and the circuit board through the first flat plate part is not influenced; the connection sheet is limited by the installation groove; therefore, connection between theconnection sheet and the bus bar is relatively steady; the connection strength between the connection sheet and the bus bar is increased; the bending part positioned in the installation groove also can increase the contact area between the connection sheet and the bus bar; and the overload capacity is increased.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a sampling assembly and a battery module. Background technique [0002] Today, with the increasing development of battery technology, the reliability of the structure in the battery pack and battery module is the guarantee for the safe operation of the battery system. In order to ensure the safe operation of the battery system, the battery module will sample information such as the voltage and temperature of each single battery. At present, battery module sampling methods include wire harness sampling, bonding sampling, and connecting sheet sampling, among which connecting sheet sampling is widely used. When using the connecting piece sampling structure, it is necessary to ensure the connection strength between the connecting piece and the bus bar. For this reason, in the prior art, the bus bar and the connecting piece are generally fixed by increasing the welding strength of...
