Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If shunt current and voltage calculations are used for DG control, then the control method is simple, but the measurement precision and energy management accuracy deteriorate
Solution Approach 1:
The patent introduces a smart battery management system as an intermediary component between the battery and the DG control system. This BMS acts as a mediator that provides accurate SOC measurements through communication protocols, resolving the contradiction by enabling precise measurement without requiring complex calculation circuits in the DG controller.
2Device complexity
If shunt measurements are used to approximate battery state, then the device complexity is reduced, but the energy management performance and flexibility worsen
Solution Approach 1:
The patent implements a feedback mechanism where the smart battery management system continuously monitors battery parameters and communicates accurate SOC data back to the DG control system. This feedback loop enables optimal energy management decisions by providing real-time, precise battery state information, thereby improving energy management efficiency without proportionally increasing device complexity.
3Ease of operation
If traditional voltage and current calculations are used, then the system is easier to operate, but the adaptability to modern power management frameworks deteriorates
Solution Approach 1:
The patent makes the battery management system universal by equipping it with standard communication protocol interfaces that can integrate with various modern power management frameworks and DG control systems. This multi-functionality approach allows the system to maintain ease of operation through standardized interfaces while simultaneously improving adaptability to different modern power management architectures.
