Battery Compartment Port Structure for Fast Pack Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs have complex structures that make disassembly and maintenance inconvenient and costly, leading to long maintenance times and high costs due to the need for assembling and disassembling entire packs or modules.
Innovation Solution
A battery compartment with a simple structure featuring male and female port poles for direct electrical connections, allowing for easy assembly and disassembly without an external connection bar, reducing production costs and improving maintenance efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery cells are assembled in a closed box body to form an entire battery pack structure, then the battery system is complete and functional, but the assembly and maintenance become extremely inconvenient with long maintenance time and high maintenance cost
Solution Approach 1:
The battery pack is divided into multiple independent battery compartments, each containing a subset of battery cells. This segmentation allows individual compartments to be accessed, removed, or replaced without affecting the entire battery pack, thereby improving maintenance convenience while maintaining system completeness.
2Ease of repair
If battery cells are integrated into modules to enable individual module assembly and disassembly, then maintenance becomes slightly more convenient, but the module structure becomes complex and maintenance time remains long
Solution Approach 1:
The battery pack is segmented into battery compartments with straightforward structures that contain battery cells in simple arrangements. This segmentation achieves maintenance便利性 without introducing complex module structures, as each compartment can be independently accessed and serviced with minimal complexity.
Solution Approach 2:
The connection bars and electrical connection structures are extracted and integrated directly into the battery compartment design, eliminating the need for complex external module interconnections. This simplifies the overall structure while maintaining the ability to independently service individual compartments.
3Reliability
If connection bars are externally disposed to connect battery compartments, then electrical connectivity is achieved, but the production cost increases
Solution Approach 1:
The connection bar structure is merged with the battery compartment housing, forming an integrated assembly. This combining of the connection function with the structural housing eliminates the need for separate external connection bars, reducing part count and production cost while maintaining reliable electrical connectivity between compartments.
