Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery pack cooling structures are inefficient, leading to high design costs and reduced performance due to the inability to effectively cool both cells and distribution boxes within the battery pack.
Innovation Solution
A battery pack design that integrates a thermoregulation member with a whole flow channel communicating with a panel, allowing both cells and distribution box components to be cooled, reducing the need for additional pipe joints and cooling structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a cooling structure is arranged in a battery box to cool cells, then cell cooling is improved, but distribution box cooling is insufficient and additional cooling structures are required
Solution Approach 1:
The cooling structure is designed to serve dual purposes: it cools both the battery cells and the distribution box components through a unified flow channel system. The first flow channel in the panel cools distribution box components while the second flow channel in the thermoregulation member cools cells, both using the same cooling medium circulation system.
Solution Approach 2:
The patent merges the cooling functions for cells and distribution box into a single integrated cooling system. The thermoregulation member connects the battery box to the panel, creating a unified cooling network that eliminates the need for separate cooling structures for each component.
2Temperature
If separate cooling structures are arranged for cells and distribution box, then cooling coverage is improved, but design costs and system complexity increase
Solution Approach 1:
The integrated cooling system allows a single cooling structure to provide comprehensive cooling coverage for both cells and distribution box components, eliminating the need for multiple separate cooling systems and reducing design costs.
Solution Approach 2:
The cooling system is segmented into functional zones (first flow channel for distribution box, second flow channel for cells) within a unified structure, allowing targeted cooling of different components while maintaining system integration and cost efficiency.
3Temperature
If additional pipe joints are provided for connecting cooling structures, then cooling connectivity is improved, but system reliability and life are reduced
Solution Approach 1:
The patent combines the cooling pathways into a continuous flow channel system where the first and second flow channels are integrally connected, minimizing the number of pipe joints and connections required, thereby improving system reliability and extending service life.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design achieves efficient temperature regulation of both cells and distribution box components, lowering cooling costs and preventing life degradation from non-uniform temperatures, enhancing safety and reducing the overall volume of the battery pack.
Implementation Method 1
The thermoregulation member is connected with the battery box. The thermoregulation member has a second flow channel connected with the first flow channel... through arrangement of a whole flow channel that communicates a thermoregulation member with a panel, not only a cell of the battery pack can be cooled, but also electrical elements in a distribution box can be cooled
