Bus Bar Holder for Battery Pack Connection Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bus bar connection methods for battery packs are prone to errors and accidents due to unstable and careless operation, lacking efficient and error-free mechanisms for connecting unit battery cells.
Innovation Solution
A bus bar holder with a holder body and bus bar receivers that securely mount and support bus bars, utilizing connection holes, support hooks, grooves, and ribs to stabilize bus bars perpendicular to the lengthwise direction, ensuring accurate and stable electrical connections between unit battery cells, and incorporating a rotatable cover to prevent exposure and potential short circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bus bars are connected manually without a holder, then the connection process is simple, but errors and accidents occur due to unstable and careless operation
Solution Approach 1:
A bus bar holder is introduced as an intermediary device between the bus bars and the battery pack structure. The holder includes multiple receivers that securely position bus bars during connection, preventing careless operation while maintaining a relatively simple overall device structure.
Solution Approach 2:
The bus bar holder pre-positions and secures the bus bars in correct locations before actual electrical connection occurs. The receivers hold the bus bars in place, ensuring proper alignment and preventing operational errors during the connection process.
2Stability of the object's composition
If bus bars are securely fixed with multiple support structures, then connection stability is improved, but manufacturing complexity increases
Solution Approach 1:
The bus bar holder is segmented into multiple receivers, each independently supporting a bus bar. This modular design provides stable support through multiple contact points while keeping each individual receiver simple in structure, facilitating easier manufacturing.
Solution Approach 2:
The holder structure serves multiple functions simultaneously: it positions bus bars, secures them during connection, and provides structural support. This multi-functionality reduces the need for separate components, simplifying manufacturing while maintaining stability.
3Manufacturing precision
If connection holes are formed through bus bar receivers, then electrical connection accuracy is improved, but manufacturing precision requirements increase
Solution Approach 1:
The connection function is segmented into dedicated connection holes within the receivers rather than requiring complex external alignment mechanisms. Each receiver has its own connection holes, simplifying the overall structure while ensuring accurate electrical connections through pre-formed openings.
