High-strength battery cell support

Abstract

The invention provides a high-strength battery cell support. Flexible connection of a plurality of battery cell support units is achieved via cooperation of splicing blocks and splicing grooves and cooperation of first installation grooves and I-shaped blocks, replacement efficiency of the battery cells is improved, the structure is simple, and meanwhile each battery cell is separated from another one by using the battery cell support unit, so that a short circuit risk caused by broken skin of the battery cells is avoided; two bottom frames are connected by an upper support arm and a lower support arm to form a stable support structure, and thus mechanical strength of the battery cell support is improved. The battery cell is embedded between the two bottom frames, and when external force, no matter longitudinal acting force or transverse acting force, is applied to the battery, most stress is borne by the battery cell frame, so that a damage risk of the battery caused by excessive stress is greatly reduced, and thus better protection is provided for the battery cell.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a high-strength battery cell support. Background technique [0002] As a green sunrise industry, electric vehicles have been developing in China for ten years. In terms of electric vehicles, by the end of 2010, China's electric vehicles had reached 120 million, and the annual growth rate was 30%. From the perspective of energy consumption, electric vehicles are only one-twelfth of that of cars; from the perspective of development trends, the market prospect of the electric vehicle industry is still promising. In recent years, lithium batteries have been used more and more widely in the field of power batteries, and are often used as batteries for electric vehicles. Because electric vehicles often bump during driving, the battery will also bump along with it, so the battery is required to have Certain mechanical strength to ensure that the battery is not damaged due to bumps. ...

AI Technical Summary

Problems solved by technology

Some cell brackets are usually composed of two parts that fix the top of each cell and the bottom of each cell. These two parts are independent of each other. Although they can prevent collisions between cells, they can also enhance the stability of the battery. Mechanical strength, but because the two parts are not connected to each other, when the battery is subjected to external force, whether it is a longitudinal force or a transverse force, most of it is borne by the battery itself. , the mechanical strength of the existing cell support with this structure is still insufficient, and the protection effect on the cell is poor
