Staggered Busbar Assembly for Compact Battery Pack Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing busbar assemblies for battery packs require multiple structural components stacked in layers, leading to a large occupied space and difficulty in achieving a miniaturized design.
Innovation Solution
A busbar assembly with a first busbar configured to connect two adjacent battery units, featuring a first connection part and a second connection part in staggered arrangement to match the vertical distance between the electrode terminals, thereby reducing space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple structural components are stacked in layers to connect battery units with height difference, then the connection function is achieved, but the occupied space increases
Solution Approach 1:
The busbar connection structure transitions from a planar arrangement to a three-dimensional staggered arrangement. The first and second connection parts are positioned at different heights (vertical dimension) to match the height difference between electrode terminals of adjacent battery units, eliminating the need for multiple layered components and reducing overall space occupation.
2Adaptability or versatility
If multiple structural components are used to accommodate height difference, then the connection adaptability is improved, but the device complexity increases
Solution Approach 1:
Multiple connection functions are merged into a single integrated busbar structure. The first connection part and second connection part form a unified busbar that simultaneously connects to both electrode terminals of adjacent battery units, eliminating the need for separate structural components and simplifying the overall device complexity.

AI summary
A busbar assembly includes a first busbar configured to connect two adjacent battery units. The first busbar includes a first connection part and a second connection part. The first connection part is used to connect a first electrode terminal of one of the battery units. The second connection part is used to connect the second electrode terminal of the other one of the battery units, and the second connection part and the first connection part are in staggered arrangement. The first connection part and the second connection part of the first busbar are in staggered arrangement, to match a vertical distance between a lead surface of the second electrode terminal and a lead surface of the first electrode terminal on a same side of the battery units.
