Battery Module Support Components for External Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of vehicle power batteries is inconvenient and has low connection reliability due to the need for electrical connections and welding within a confined box cavity, limiting operation and reliability.
Innovation Solution
A battery module design featuring support components that are fixed to the battery units before placement into a box, allowing for external electrical connections and increased rigidity, facilitating easier assembly and improved connection reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If battery units are assembled inside the box cavity, then the battery module structure is compact, but the operation convenience and connection reliability deteriorate due to space constraints
Solution Approach 1:
The patent divides the battery module assembly into two stages: first assembling battery units with support components outside the box, then placing the pre-assembled units into the box cavity. This segmentation allows complex operations to be performed in a more accessible environment while maintaining compact final packaging.
Solution Approach 2:
The support components are fixed to the battery units before they are placed into the box cavity. This preliminary action enables electrical connections and structural assembly to be completed in advance, avoiding the space constraints and operational difficulties of working inside the confined box during final assembly.
2Stability of the object's composition
If battery units are assembled inside the box cavity, then the structure is integrated, but the connection reliability deteriorates due to limited working space
Solution Approach 1:
Electrical connections and welding of sampling lines are performed on battery units before they are placed into the box cavity. This preliminary action ensures that connection operations can be completed with proper tool access and working space, thereby improving connection reliability while maintaining structural integration in the final assembled state.
3Strength
If support components are added to provide external support, then the rigidity and ease of assembly improve, but the device complexity increases
Solution Approach 1:
The support components serve multiple functions: they provide structural support to increase rigidity, enable preliminary assembly operations outside the box, and facilitate electrical connections. By consolidating these functions into a single component, the patent avoids increasing overall device complexity while achieving multiple benefits.
