Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional charging stations are built to support BEV charging infrastructure, then charging availability is improved, but capital cost and device complexity increase significantly
Solution Approach 1:
The patent enables BEVs to charge each other directly through peer-to-peer energy transfer. The source vehicle's battery system serves as the charging source, eliminating the need for external charging stations. This self-service approach allows vehicles to provide charging services to one another, reducing infrastructure requirements while maintaining charging availability.
Solution Approach 2:
The charging adapter system enables multiple charging modes including direct vehicle-to-vehicle charging, connection to traditional charging stations, and wireless charging. This multi-functional capability allows a single system to serve various charging needs without requiring separate infrastructure for each charging type, thereby reducing overall system complexity.
2Productivity
If DC fast charging stations are deployed to reduce charging time, then charging speed is improved, but capital intensity and loss of time for infrastructure development increase
Solution Approach 1:
Vehicles equipped with the charging adapter can immediately provide fast charging services to other vehicles without waiting for infrastructure deployment. The source vehicle's battery system directly supplies power to the receiving vehicle through the adapter, enabling instant charging capability availability without any infrastructure lead time.
Solution Approach 2:
The charging adapter acts as an intermediary device that enables direct power transfer between vehicles. This portable intermediary eliminates the need for fixed infrastructure while maintaining fast charging capability, as the adapter facilitates high-speed energy transfer between connected vehicles on demand.
3Reliability
If charging stations are built to address range anxiety, then customer confidence is improved, but utilization efficiency deteriorates due to poor usage rates
Solution Approach 1:
Vehicles can charge each other directly through peer-to-peer energy transfer, creating a distributed charging network where any vehicle with excess capacity can serve others. This eliminates the need for centralized charging stations that suffer from low utilization, as charging services are provided directly at the point of need through vehicle-to-vehicle connections.
Solution Approach 2:
The system dynamically adjusts charging parameters such as power transfer rate, charging voltage, and current based on the source vehicle's battery state and the receiving vehicle's requirements. This adaptive parameter adjustment optimizes charging efficiency for each interaction, ensuring high utilization of available charging capacity without requiring underutilized fixed infrastructure.
