Modular Sensing Assembly for Expandable Battery Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery modules require a new housing design when the number of stacked battery cells changes, limiting the expandability and efficiency of the sensing assembly.
Innovation Solution
A sensing assembly with detachable sensing housing parts that can be easily expanded by adjusting the number of components to match the number of battery cells, featuring a block-to-block coupling pattern and including a sensing bus bar and temperature sensor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single housing structure is used for the sensing assembly, then the housing can cover the protruding portions of the electrode leads, but when the number of battery cells changes, a new housing design is required
Solution Approach 1:
The sensing assembly housing is divided into multiple detachable housing parts that can be assembled in different configurations. Each housing part can accommodate a specific number of battery cells, and the parts are connected through coupling structures (convex protrusions and concave grooves) to form a complete housing that adapts to various battery cell arrangements without requiring complete redesign
Solution Approach 2:
The housing structure transitions from a fixed, static design to a dynamic, reconfigurable design. The detachable housing parts can be assembled and disassembled to adapt to changing battery cell configurations, allowing the sensing assembly to dynamically adjust to different capacity requirements
2Adaptability or versatility
If the number of battery cells is increased or decreased to change capacity, then the charge/discharge capacity or output voltage changes, but the housing must be redesigned
Solution Approach 1:
The housing is segmented into standardized modular parts that can be quickly assembled in different quantities based on the required battery cell configuration. This eliminates the need for time-consuming redesign processes when capacity requirements change
Solution Approach 2:
The same set of housing parts can serve multiple functions by being assembled in different configurations to accommodate different numbers of battery cells, making the housing system universally applicable to various capacity requirements
