Busbar and battery module

Abstract

The invention provides a busbar and a battery module. The busbar comprises an insulating bracket and a copper bar, a plurality of limiting grooves are formed in the insulating bracket at intervals, the copper bar comprises a plurality of copper sheets which are connected with one another, and the plurality of copper sheets are inserted into the plurality of limiting grooves in a one-to-one correspondence manner; and first fixing pieces are arranged on the first side wall and the second side wall of each limiting groove correspondingly, second fixing pieces matched with the first fixing piecesare arranged on the third side wall and the fourth side wall of the copper sheets correspondingly, and the copper sheets can be fixed into the limiting grooves through cooperation of the first fixingpieces and the second fixing pieces. Through the cooperation of the first fixing pieces and the second fixing pieces, the copper sheets can be limited in the limiting grooves and cannot slide or falloff, and the stability of the busbar is improved; and the copper sheets are correspondingly connected with the tabs of battery cells, and the tabs of the adjacent battery cells can be prevented from being contacted through separation of the limiting grooves, so that the risk of short circuit of the battery pack is reduced, and the busbar use safety is improved.

Description

Technical field [0001] The present invention relates to the technical field of lithium ion batteries, in particular to a bus bar and a battery module. Background technique [0002] Lithium-ion energy storage system (Battery Energy Storage System, BESS) is the most widely used energy storage system. In comparison, the advantages of BESS are: first, lower cost, mature technology, and high charge and discharge multiples; second, modules It has good performance and can be used as a distributed energy storage device. [0003] At present, when manually installing the busbar, the copper busbar usually needs to be put into the busbar bracket from above, and the copper busbar is easy to fall off, and even short-circuit the battery module. [0004] It can be seen that the safety of the installation structure of the busbar in the prior art is poor. Summary of the invention [0005] The purpose of the embodiments of the present invention is to provide a bus bar and a battery module, which solve...
