Document Type and Number:
WIPO Patent Application WO/2024/031996
Kind Code:
A1
Abstract:
The present invention relates to a module of battery cell stacks connected in series by means of tabs. The module comprises battery cell stacks, a middle sampling connection assembly and a shell, wherein at least one battery cell is provided in each battery cell stack, tabs are provided at two ends of the battery cell, and there are at least two battery cell stacks; the middle sampling connection assembly is arranged between two battery cell stacks and is connected to a tab on one side of each of the two battery cell stacks, such that battery cells corresponding to each other in adjacent battery cell stacks are connected in series, and thus all battery cell stacks form a battery cell group; and the shell is arranged outside the battery cell group. In the present module, a plurality of battery cell stacks are connected in series by means of tabs to form a battery cell group, such that the integration efficiency of the module is improved, thereby improving the energy density of a system and improving the endurance capability of the system.
