Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a non-modular cooled battery pack encloses several cell assemblies in one large liquid tank, then cooling efficiency is improved, but the pack becomes bulky and heavy, making it difficult to employ on various sizes of vehicle platforms
Solution Approach 1:
The battery pack is divided into multiple modular battery modules, each with its own cooling channels integrated into the battery case. This segmentation allows each module to be independently cooled with smaller, lighter cooling structures, while collectively providing the same cooling efficiency as a large unified tank.
2Ease of manufacture
If conventional modular battery packs use fixed parameter modules, then manufacturing simplicity is improved, but flexibility for various application fields deteriorates
Solution Approach 1:
The battery module design incorporates dynamic configurability where the number, arrangement, and orientation of battery cells can be adjusted within the standardized battery case. The cooling channel configuration allows for flexible adaptation to different thermal management requirements. This enables the same basic module structure to be customized for different application fields (different power requirements, space constraints, and thermal loads) while maintaining manufacturing simplicity through standardized components.
