Liquid-Cooled Battery Cabin Layout for Higher Cell Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy-storage prefabricated cabins have low energy density due to the use of complex structural members that occupy a large part of the installation space, reducing the number of battery cells and power storage capacity.
Innovation Solution
The design includes a liquid-cooling structure with battery cells directly installed on its side surfaces, eliminating intermediate structural members like module frames and battery frames, and utilizing a frame with longitudinal and cross beams to define the installation space, allowing for a battery-frame-free configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex structural members (limiting assemblies, harness devices, module frames, battery frames) are used to fix and support battery packs and clusters, then the structural stability and reliability are improved, but the installation space utilization rate decreases and the number of battery cells is reduced
Solution Approach 1:
The patent merges the functions of module frames, battery frames, and limiting assemblies into an integrated box body structure. The box body directly accommodates battery clusters without requiring intermediate structural members, eliminating redundant components and maximizing installation space while maintaining structural integrity.
Solution Approach 2:
The patent extracts and eliminates unnecessary intermediate structural members (module frames, battery frames, limiting assemblies) from the system. By removing these redundant components, the design achieves a simplified structure that uses space more efficiently and increases the number of battery cells that can be installed.
2Stability of the object's composition
If complex structural members and intermediate processes (module assembly, battery pack assembly, battery cluster assembly) are used, then the structural integrity is improved, but the device complexity increases and production costs increase
Solution Approach 1:
The patent combines multiple assembly processes (module assembly, battery pack assembly, battery cluster assembly) into a single integrated assembly process. Battery clusters are directly assembled into the box body without requiring intermediate structural members, thereby reducing device complexity and the number of structural components while maintaining structural integrity.
Solution Approach 2:
The patent removes intermediate structural members and assembly processes from the system. By eliminating module frames, battery frames, and limiting assemblies, the design simplifies the overall structure and reduces the number of parts, making the system easier to manufacture and maintain while preserving structural strength.
3Ease of manufacture
If a traditional multi-level assembly structure (modules to battery packs to battery clusters) is used, then the modularity and ease of assembly are improved, but the space occupation by structural members increases and energy density decreases
Solution Approach 1:
The patent merges the traditional multi-level assembly hierarchy into a simplified direct assembly structure. Instead of assembling modules into battery packs and then into battery clusters, battery clusters are directly installed into the box body. This eliminates the space-consuming intermediate structures while maintaining the modular nature of the system for ease of manufacture and assembly.
