Busbar for lithium battery module

Abstract

The invention discloses a busbar for a lithium battery module. The busbar comprises a fixed cover plate, a confluence sheet, a battery cell fixing frame and a connecting bottom plate; the fixed coverplate is mounted and fixed on the upper end surface of the battery cell fixing frame; the lower end surface of the battery cell fixing frame is fixed with the connecting bottom plate; therefore, double-sided clamping is carried out on the battery cell fixing frame; the confluence sheet is arranged in the fixed cover plate; the battery cell fixing frame comprises an upper supporting frame and a lower auxiliary bracket; the upper support frame and the lower auxiliary bracket are mutually matched and fixed; a plurality of battery mounting holes I are formed in the end surface of the upper supportframe; a battery mounting hole II is formed in a corresponding position in the lower auxiliary bracket, therefore, the lithium battery is placed in the battery cell fixing frame; and a heat dissipation assembly is further arranged in the end face of the side, close to the lower auxiliary bracket, of the upper supporting frame, heat dissipation is conducted on the lithium battery in time, the service life of the battery is prolonged, the safety of the battery is improved, and the fixed cover plate and the connecting bottom plate are fixed through connecting supporting column threads.

Description

technical field [0001] The invention relates to the technical field of garlic processing equipment, in particular to a bus bar for lithium battery modules. Background technique [0002] Lithium batteries are widely used in new energy industries, such as automobiles, logistics vehicles, large-scale mobile energy storage, etc. A single lithium-ion battery cell is first assembled into a battery module or directly assembled into a battery pack. It is connected with the battery cell and between the module and the module through a conductor to realize the series and parallel connection of the battery, which is used to realize the series and parallel conductor parts; the design of the bus bar needs to take into account the conductive resistance and the connection strength. The parts of the battery busbar are rigid. During the driving process of the vehicle, the vibration will cause the relative displacement between the cells, and the welding points and fastening connections will be...

Problems solved by technology

[0002] Lithium batteries are widely used in new energy industries, such as automobiles, logistics vehicles, large-scale mobile energy storage, etc. A single lithium-ion battery cell is first assembled into a battery module or directly assembled into a battery pack. It is connected with the battery cell and between the module and the module through a conductor to realize the series and parallel connection of the battery, which is used to realize the series and parallel conductor parts; the design of the bus bar needs to take into account the conductive resistance and the connection strength. The battery busbar parts are very rigid. During the driving process of the vehicle, the vibration will cause the relative displacement between the cells, and the welding points and fastening connection pairs will bear a large force, resulting in deformation, loosening, cracking, and poor contact. Therefore it is necessary to propose a bus bar for lithium battery modules to solve the above problems
