Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power battery charging devices cannot flexibly adjust charging and discharging voltages to match the needs of new power batteries with higher voltages, leading to compatibility issues and inefficiencies, as most devices can only handle lower voltages and lack the ability to adapt to varying load device requirements.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the charging device uses a fixed circuit structure, then the device complexity is reduced, but the adaptability to different voltage requirements is worsened
Solution Approach 1:
The patent implements dynamic switching between different circuit configurations using switch assemblies. The circuit structure transitions from static to dynamic, allowing the system to adapt between direct charging mode and boost charging mode based on voltage requirements, thereby resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The patent designs a universal charging circuit that can perform multiple functions (direct charging and boost charging) through a single integrated structure. By incorporating switch assemblies and energy storage elements, the circuit becomes multi-functional, capable of handling different voltage scenarios without requiring separate dedicated circuits for each mode.
2Adaptability or versatility
If the circuit structure is changed to accommodate higher voltages, then the voltage adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent segments the charging circuit into modular components: switch assemblies, energy storage elements, and control units. This segmentation allows independent optimization of each module and simplifies the overall system design. The switch assembly can be configured in different states without redesigning the entire circuit, reducing complexity while maintaining voltage regulation capability.
Solution Approach 2:
The patent changes circuit parameters (switching states, connection configurations) rather than altering the fundamental circuit structure. By adjusting the state of switch assemblies and the configuration of energy storage elements, the system achieves voltage regulation through parameter modification, avoiding the need for complex structural changes.
3Adaptability or versatility
If multiple separate circuits are used for different charging modes, then the voltage adaptability is improved, but the device complexity and loss of energy increase
Solution Approach 1:
The patent merges direct charging and boost charging functions into a single integrated circuit. The switch assembly and energy storage elements are shared between different charging modes, eliminating redundant components. This consolidation reduces energy losses that would occur in separate circuits and simplifies the overall system while maintaining charging mode flexibility.
Solution Approach 2:
The patent creates a universal charging circuit that serves multiple functions through a single design. The same circuit components (switches, energy storage elements) are used across different charging modes, reducing total energy consumption compared to multiple dedicated circuits and minimizing energy loss while achieving charging mode flexibility.
