Abstract

The invention discloses a bus bar for supporting high-power application of a battery pack. The bus bar comprises a plurality of conductive sheets, wherein a pair of wiring terminals is arranged on each conductive sheet; each pair of wiring terminals is arranged in the length direction of the corresponding conductive sheet; a section, positioned between each pair of wiring terminals, of the corresponding conductive sheet has an arc-shaped bump structure; each arc-shaped bump structure is arranged in the width direction of the corresponding conductive sheet; a connecting block is arranged between every two adjacent conductive sheets and also has an arc-shaped bump structure; two arc-shaped end parts of each connecting block with the arc-shaped bump structure are connected with the arc-shaped bump structures of the adjacent conductive sheets respectively; each connecting block is connected with the arc-shaped bump structures of the corresponding conductive sheets to form an integrated arc-shaped bump structure. The wiring terminals are connected with poles of a battery, and all the poles can be elastically connected through the arc-shaped bump structures on the conductive sheets and the connecting blocks with the arc-shaped bump structures; meanwhile, the current sharing effect can be achieved by the connecting blocks.

Description

Technical field [0001] The invention relates to a bus bar, in particular to a bus bar supporting high-power applications of battery packs. Background technique [0002] In a large-scale energy storage system, single batteries need to be connected in parallel to achieve the expansion of the capacity and power characteristics of the energy storage system to support high-current applications. Therefore, the poles of the single batteries need to be connected by a bus. . Since the battery is deformed at the charging and discharging point, the connection between the poles needs to be flexible to avoid the stress between the battery and the bus bar from damaging the battery poles, which is not available in the existing bus bar. Characteristics. Summary of the invention [0003] In order to solve the above technical problems, the present invention provides a bus bar supporting high-power applications of battery packs, and realizes the elastic connection between the poles. [0004] In ord...
