Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional battery pack architecture is used, then the system structure is simple, but the voltage output flexibility is limited to DC or single-phase AC only
Solution Approach 1:
The battery pack is divided into multiple independent battery modules, each capable of providing voltage output. The switching circuit selectively connects these modules to different output terminals, enabling flexible configuration of voltage outputs including DC, single-phase AC, and three-phase AC without requiring a completely different system architecture for each mode.
Solution Approach 2:
The system employs a dynamic switching circuit that can reconfigure the connections between battery modules and output terminals in real-time. This dynamic reconfiguration allows the same battery pack structure to adaptively provide different voltage output types (DC, single-phase AC, three-phase AC) based on load requirements, achieving versatility without proportional increase in structural complexity.
2Adaptability or versatility
If single-phase inverter is used for DC to AC conversion, then the system complexity is reduced, but the power supply capability is limited to single-phase AC only
Solution Approach 1:
The battery pack architecture is designed with universal output capability through a switching circuit that can configure the same battery modules to provide DC output, single-phase AC output, or three-phase AC output. This multi-functional design eliminates the need for separate inverter systems for different power supply modes, achieving enhanced power supply capability without proportional increase in overall system complexity.
3Adaptability or versatility
If advanced battery pack architecture with series-control is used, then AC and rectified AC voltage outputs can be provided directly, but the output is limited to two-line output forming a single phase
Solution Approach 1:
The system transitions from a two-line single-phase output configuration to a multi-line three-phase output configuration by adding more output terminals and corresponding switching circuitry. The same series-control battery module architecture is extended to support three-phase output by distributing battery modules across multiple phases and using the switching circuit to connect appropriate modules to each phase terminal, achieving enhanced output phase configuration capability.
4Reliability
If multiple energy sources are managed with conventional architecture, then the system is simpler, but the voltage profile optimization and uninterrupted operation are compromised
Solution Approach 1:
A circuit module with switching circuitry is introduced as an intermediary between multiple battery modules and the output terminals. This intermediary component manages the complex task of selecting and connecting appropriate battery modules based on their voltage profiles and operational status, ensuring uninterrupted power supply while optimizing voltage output. The switching circuit acts as a mediator that handles the complexity of multi-source management, allowing the overall system to achieve high reliability without requiring complete redesign of the battery architecture.
