Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If energy storage devices with different state of charge (SoC) are used together, then the system can operate with available batteries, but the overall system efficiency decreases and battery life is shortened
Solution Approach 1:
The system performs preliminary sorting and matching of batteries based on their characteristics (SoC, temperature, capacity, age) before they are deployed together in the system. This advance preparation ensures that only compatible batteries with similar characteristics are grouped together, preventing future performance degradation and extending battery life while maintaining system productivity
Solution Approach 2:
The system dynamically monitors and adjusts battery grouping based on changing parameters such as state of charge, temperature, capacity, and age. By continuously evaluating these parameters and reconfiguring battery pairs accordingly, the system maintains optimal matching conditions, ensuring both high efficiency operation and extended battery lifespan
2Productivity
If energy storage devices with different temperatures are used together, then charging can proceed without temperature restrictions, but battery performance decreases and charging behavior is negatively impacted
Solution Approach 1:
The system performs preliminary temperature assessment and matching of batteries before charging operations. By pre-grouping batteries with similar temperature characteristics, the system ensures that charging proceeds under optimal thermal conditions, maintaining both charging speed and battery performance without negative impacts from temperature mismatches
Solution Approach 2:
The system dynamically adjusts battery pairing based on temperature parameters during charging operations. By monitoring temperature changes and reconfiguring battery groups accordingly, the system maintains optimal thermal matching, ensuring both high charging productivity and reliable battery performance throughout the charging process
