Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all storage batteries are collectively connected in parallel during discharge, then the system can supply power to loads during power outage, but the individual characteristics of different battery types are not utilized
Solution Approach 1:
The patent segments the storage battery system into multiple independent battery groups (first storage battery group, second storage battery group, etc.), each capable of independent control. This allows selective connection of specific battery groups based on discharge applications, rather than connecting all batteries in parallel. The segmentation enables the system to match specific battery types with specific discharge scenarios, thereby utilizing individual battery characteristics while maintaining power supply reliability.
2Productivity
If storage batteries are selectively used based on charge-discharge applications, then the system can optimize battery usage for specific requirements, but the control complexity increases
Solution Approach 1:
The patent implements dynamic control capabilities in the control device, allowing real-time adjustment of battery group connections based on discharge application requirements. The control device can dynamically determine which battery groups to connect or disconnect based on factors such as discharge duration, power requirements, and battery state of charge. This dynamic control optimizes battery usage efficiency while managing complexity through automated decision-making algorithms.
Solution Approach 2:
The control device incorporates feedback mechanisms to monitor battery status, discharge application requirements, and system performance. Based on this feedback, the control device adjusts the connection status of different battery groups to optimize productivity. The feedback loop enables the system to learn from operational data and improve battery selection and allocation strategies over time, managing control complexity through intelligent algorithms.
