Abstract

The invention provides components of a battery pack, which comprise a base part and a plurality of guide parts, the guide parts are arranged on the base part and are distributed along a second direction, each guide part extends along the same direction along a first direction, a guide groove along the first direction is defined between two adjacent guide parts, and the front ends of the two adjacent guide parts define an inlet of the guide groove. The second direction is not parallel to the first direction. The invention also provides the battery pack which comprises battery cells and the components of the battery pack, and the tab of each battery cell is correspondingly arranged in one guide groove. The invention also provides a battery pack cell assembly method, and the cell is assembledby using the components of the battery pack. According to the battery pack, the components of the battery pack and the battery cell assembly method of the battery pack, the tabs of the battery cellsare arranged in the guide grooves, so that the tabs of the battery cells are not in contact with one another, the risk of contact short circuit is avoided, and the battery pack is suitable for high-efficiency and low-cost automatic battery cell assembly.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery pack, components thereof, and a method for assembling cells of the battery pack. Background technique [0002] The battery pack usually contains cells, and the tabs of each cell are electrically connected to each other. The tabs usually have poor structural stability, especially for soft-packed lithium-ion batteries, which are affected by the material and structural characteristics of the aluminum-plastic film on the surface, and the tabs are easy to bend. The stability is poor, the battery assembly is difficult, and the assembly speed is slow. Especially for battery packs without brackets, the battery assembly must rely on additional tools to assist assembly. At present, there is no high-speed, low-cost battery assembly solution that is easy to automate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a b...
