Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power storage modules in vehicles are prone to overheating due to increasing capacities of power storage devices, leading to a decline in performance and a risk of chain overheating among adjacent devices.
Innovation Solution
A power storage pack design that includes a plurality of power storage modules with binding members and a heat transfer member that transfers heat between the modules, with the heat transfer member having connecting parts thermally connected to the surfaces of the modules and arranged to be shifted from each other in the first direction, thereby diffusing heat and preventing chain overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If power storage devices are arranged adjacently in power storage modules, then space utilization is improved, but heat transfer between adjacent devices causes chain overheating and performance decline
Solution Approach 1:
A heat transfer member is introduced as an intermediary component between adjacent power storage modules. This heat transfer member includes a first connecting part thermally connected to a surface of the first power storage module, a second connecting part thermally connected to a surface of the second power storage module, and a coupling part thermally connecting the first and second connecting parts. The heat transfer member actively manages heat flow between modules, preventing chain overheating while maintaining compact arrangement.
2Quantity of substance
If power storage device capacity is increased, then energy storage capability is improved, but heat generation increases leading to chain overheating risk
Solution Approach 1:
The heat transfer member serves as a mediator that intercepts and manages heat generated by high-capacity power storage devices before it can transfer to adjacent devices. By providing controlled thermal pathways through the coupling part, the system dissipates heat effectively while maintaining the high energy storage capacity of individual devices.
