Battery Container Partition Structure with Independent Pressure Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery pack pressure relief structures are prone to damage during assembly, affecting their pressure relief effectiveness due to structural limitations.
Innovation Solution
A battery container with a partition structure that includes a mounting plate and an independently formed pressure relief structure, allowing air from the battery accommodating space to be collected and discharged into an exhaust space, thereby preventing damage and ensuring reliable pressure relief.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the pressure relief structure is integrated into the partition structure, then the structural complexity is reduced, but the pressure relief structure is prone to damage during assembly and its reliability is compromised
Solution Approach 1:
The pressure relief structure is separated from the partition structure into an independent component. The partition structure includes a mounting plate with a mounting cavity, while the pressure relief structure is a separate element that can be independently formed, assembled, and replaced without affecting the partition structure itself.
2Reliability
If the pressure relief structure is made as a separate independent component, then the reliability and resistance to assembly damage are improved, but the device complexity increases
Solution Approach 1:
The pressure relief structure is separated from the partition structure into an independent component. The partition structure includes a mounting plate with a mounting cavity, while the pressure relief structure is a separate element that can be independently formed, assembled, and replaced without affecting the partition structure itself.
Solution Approach 2:
The mounting plate integrates a mounting cavity specifically designed to accommodate the pressure relief structure, creating a unified assembly that combines the partitioning function with the pressure relief function while maintaining structural simplicity.
3Ease of manufacture
If the pressure relief structure is integrated into the partition structure, then the manufacturing process is simplified, but damage during assembly affects manufacturing precision and functionality
Solution Approach 1:
The pressure relief structure is separated from the partition structure into an independent component. The partition structure includes a mounting plate with a mounting cavity, while the pressure relief structure is a separate element that can be independently formed, assembled, and replaced without affecting the partition structure itself.
Solution Approach 2:
The mounting plate is pre-formed with a mounting cavity that precisely accommodates the pressure relief structure. This preliminary preparation of the mounting interface ensures proper alignment and positioning during assembly, maintaining manufacturing precision without requiring complex integrated forming processes.

AI summary
A battery container includes a container body (10) and a partition structure (20). The partition structure (20) is arranged in the container body (10) to form a battery accommodating space (11) and an exhaust space (12). The partition structure (20) includes a mounting plate (21) and a pressure relief structure (22). The pressure relief structure (22) and the mounting plate (21) are independently formed structures. The pressure relief structure (22) is arranged on the mounting plate. The air in the battery accommodating space (11) is able to be collected into the exhaust space (12) through the pressure relief structure (22) and discharged. A battery pack includes the battery container.
