Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the battery output voltage range is limited to adapt to one load, then the voltage matching for that specific load is improved, but the adaptability to multiple loads with different voltage demands deteriorates
Solution Approach 1:
The battery system is segmented into multiple battery modules (first battery module, second battery module, etc.) that can be independently connected in series or parallel configurations. This segmentation allows the system to provide different voltage and current outputs to match various load requirements while maintaining precise voltage control for each configuration.
Solution Approach 2:
The battery system employs dynamic switching between series and parallel connections of battery modules based on load requirements. The control device dynamically adjusts the connection configuration to adapt to different voltage and current demands, enabling the same battery system to serve multiple loads with different specifications.
2Device complexity
If the battery system uses fixed connection configuration, then the system complexity is reduced, but the ability to meet different voltage requirements of multiple loads deteriorates
Solution Approach 1:
The battery system is designed with universal multi-functionality by incorporating multiple battery modules that can be configured in different connection modes (series, parallel, or combinations). This allows a single battery system to fulfill multiple functions and serve different loads with varying voltage and current requirements without requiring separate dedicated systems for each load.
Solution Approach 2:
A control device acts as an intermediary between the battery modules and loads, managing the switching and coordination of series-parallel connections. This intermediary component enables flexible reconfiguration of the battery system to meet different voltage requirements while maintaining systematic control and minimizing overall complexity.
