Storage Battery Module Insulating Members Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In storage battery modules, heat generated by battery cells can be dissipated to the periphery, increasing internal housing temperature and potentially affecting other electrical apparatuses, and the use of outdoor air for cooling can lead to dust adherence on circuit substrates, causing corrosion or short circuits, necessitating complex and costly dust-removal systems.
Innovation Solution
A storage battery module design featuring insulating first and second members with specific thermal resistances, which cover terminal spaces and surround substrate terminals, enhancing heat transfer to cooling air while preventing dust adherence on the substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling air is blown between battery cells to cool them, then cooling efficiency is improved, but heat is expelled to the periphery causing temperature rise inside the housing and potentially affecting other electrical apparatuses
Solution Approach 1:
The patent introduces insulating members as intermediary elements positioned between the battery cells and the housing periphery. These insulating members act as mediators that block the direct path of heat transfer to the periphery, thereby preventing harmful heat dissipation while maintaining the cooling effect on battery cells.
Solution Approach 2:
The patent applies local quality by providing insulating members at specific locations where heat dissipation to the periphery occurs, rather than uniformly insulating the entire housing. The insulating members are strategically placed in the spaces between adjacent battery cells to target the specific heat transfer paths that need to be blocked.
2Temperature
If outdoor air containing dust is used as cooling air, then cooling function is achieved, but dust adheres to the circuit substrate causing corrosion or short circuit
Solution Approach 1:
The insulating members serve as intermediary barriers between the cooling air flow and the circuit substrate. These members block the direct contact between dust-laden cooling air and the substrate, preventing dust adherence while allowing the cooling air to still pass through and cool the battery cells effectively.
Solution Approach 2:
The insulating members function as protective barriers (similar to flexible shells or films) that cover and protect the circuit substrate from the harmful effects of dust-containing cooling air, while not completely sealing the cooling pathway.
3Object-affected harmful factors
If a dust-removal system is provided to prevent dust from adhering to the circuit substrate, then dust protection is improved, but the system becomes complicated in structure and manufacturing costs increase
Solution Approach 1:
The patent replaces complex active dust-removal systems with simple, passive insulating members that provide dust protection through their physical barrier function. These insulating members are simple in structure, easy to manufacture, and do not require complex mechanisms or additional energy consumption.
Solution Approach 2:
The patent extracts the dust protection function from the complex dust-removal system and implements it through simple insulating members. By separating the dust protection function from the cooling function and implementing it through a simple barrier, the overall system complexity is reduced while maintaining both functions.

AI summary
A storage battery module includes battery cells, a first member and a second member opposing the first member across a substrate. The first member closes the space between adjacent terminals, and covers an open surface of a housing in a state where the terminals of the battery cells are exposed. The first member is formed of a material having a thermal resistance greater than or equal to a first threshold. The substrate opposing the battery cells across the first member has holes through which the terminals are inserted and a conductor formed therein so as to electrically connect the terminals. The second member opposing the first member across the substrate surrounds the terminals projecting from the holes and covers the substrate with the terminals exposed from the holes. The second member is formed of a material having a thermal resistance greater than or equal to a second threshold.
