CCS hot-pressing packaging type battery cell connecting assembly

Abstract

The invention discloses a CCS hot-pressing packaging type battery cell connecting assembly which comprises a plurality of aluminum bars and conduction circuit parts correspondingly connected to the aluminum bars, the conduction circuit parts are circuit boards or wires; the assembly is characterized in that the assembly also comprises a hot-pressing film substrate, the aluminum bars and the conduction circuit parts are fixed on the hot-pressing film substrate in a hot-pressing manner; the aluminum bars are arranged in at least two rows; the conduction circuit parts are positioned on the spacing surface layer between the two adjacent rows of aluminum bars on the hot-pressing film substrate and is led out from one side of the spacing surface layer, the conduction circuit parts are provided with electric connection sections welded with the aluminum bars, and welding points of the electric connection sections and the aluminum bars are positioned between the aluminum bars and the hot-pressing film substrate. Compared with a traditional structure, the overall structure is greatly lightened, the adaptation degree to the installation space is higher, the assembling is easy, the yield is increased, the mold opening period is greatly shortened, the mold opening cost is greatly reduced, the use is safe and reliable, and the CCS hot-pressing packaging type battery cell connecting assemblyis worthy of application and popularization in the field.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a CCS heat-press packaged cell connection assembly. Background technique [0002] The battery connection system, also called CCS assembly, is installed on the battery pack to collect the voltage signal and current signal of the battery pack and balance the voltage difference of the battery pack. In the traditional battery connection system, the device used to connect with the battery includes a plastic carrier, an aluminum bar and a wire (in addition, the cover that is buckled on the plastic carrier is also included), and the plastic carrier has multiple The installation groove on which the aluminum bar is pressed and buckled and the buckle that guides the wires into bundles and presses them down. All the wires are finally gathered from one place and fixed with adhesive tape, such as the invention patent document with the application number CN201921875134.2 A disclosed b...
