Road Wireless Charging Control for Power-Shortage-Bound Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply systems for vehicles during traveling face challenges in efficiently supplying electric power to areas with power shortages, as vehicles with diverse destinations can deplete the available power, leaving insufficient power for areas in need.
Innovation Solution
A power supply system that includes a server communicating with vehicles and a power transmission device on the road, which prioritizes power supply to vehicles destined for power shortage areas by limiting charging operations for non-target vehicles using lane restrictions, power adjustments, and state-of-charge management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electric power is supplied from the same power transmission device to many vehicles at the same time, then more vehicles can be charged during traveling, but the electric power that can be supplied to vehicles whose destinations are power shortage areas decreases
Solution Approach 1:
The server implements differentiated power supply strategies based on vehicle destinations. Vehicles bound for power shortage areas receive priority power supply with higher power allocation, while vehicles not heading to such areas receive reduced or no power supply. This local quality differentiation ensures that limited power resources are concentrated on vehicles that can deliver power to critical regions.
Solution Approach 2:
The server performs preliminary determination of vehicle destinations before power supply execution. By acquiring destination information in advance and identifying power shortage areas, the server can pre-establish priority relationships and allocate power resources accordingly, ensuring that vehicles destined for power-shortage regions receive sufficient power before other vehicles do.
2Length of moving object
If power supply during traveling is implemented to transport electric power to distant places, then power can be delivered to remote areas, but power may be insufficient when multiple vehicles with diverse destinations compete for the same power source
Solution Approach 1:
The system applies differentiated power supply based on destination analysis. Vehicles heading to power shortage areas receive priority treatment with sufficient power allocation, while vehicles with other destinations receive limited power. This ensures that power transport capacity is effectively directed toward fulfilling critical power delivery needs to distant power-shortage regions.
Solution Approach 2:
The server determines vehicle destinations and power shortage area relationships in advance, establishing priority power supply relationships before actual power transmission begins. This preliminary action allows the system to optimize power allocation for long-distance power transport to critical regions, ensuring that vehicles capable of delivering power to distant power-shortage areas receive adequate power resources.
