Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a charging module in a charging pile corresponds to a fixed parking space or is shared by a limited quantity of parking spaces, then the charging module can provide dedicated charging service, but the scheduling range of the charging module is limited and utilization is insufficient
Solution Approach 1:
The patent implements inter-pile sharing that enables a charging module to serve multiple parking spaces across different charging piles. The control system dynamically allocates charging modules based on real-time charging requirements, allowing a single charging module to be shared by an unlimited number of parking spaces through networked communication between charging piles, thereby achieving multi-functionality and expanded scheduling range
2Reliability
If a charging module is fixed to a specific parking space, then the charging service is stable and reliable, but the charging apparatus cannot flexibly respond to charging power requirements of nearby parking spaces
Solution Approach 1:
The patent implements dynamic charging module allocation where the control system continuously monitors charging requirements of multiple parking spaces and dynamically assigns charging modules based on real-time power demands. The system can flexibly respond to changing charging requirements by reassigning charging modules between different parking spaces while maintaining stable and reliable charging service through automated control
3Extent of automation
If multiple charging apparatuses operate independently with separate electric energy reserves, then each charging apparatus can autonomously manage its charging operations, but the utilization of electric energy reserve in the charging apparatus is insufficient
Solution Approach 1:
The patent merges the electric energy reserves of multiple charging apparatuses into a shared pool through inter-pile sharing. The control systems of different charging piles communicate with each other to coordinate charging module allocation, allowing the combined electric energy reserve to be utilized more efficiently while maintaining automated management through centralized control and coordination
