EV Parking Pallet Control for Facility Power Supply Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking management systems for electric vehicles struggle to ensure that all parking spaces can supply power to facilities during emergencies, as not all spaces are equipped with charging and discharging devices, limiting the functionality of electric vehicles.
Innovation Solution
A system with movable pallets and controlled movement of vehicles to chargeable and dischargeable parking spaces, ensuring that electric vehicles can be parked where charging and discharging devices are installed, using a controller to optimize pallet movement based on vehicle capabilities and proximity to facilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If charging and discharging devices are installed in all parking spaces, then more electric vehicles can supply power to facilities, but installation cost and system complexity increase significantly
Solution Approach 1:
The patent introduces movable pallets that can dynamically reposition vehicles between different parking spaces. Instead of having fixed charging/discharging devices in every space, the system dynamically moves vehicles to spaces equipped with these devices, making the resource allocation flexible and adaptive to changing needs.
Solution Approach 2:
The pallet acts as an intermediary mechanism between vehicles and charging/discharging devices. Rather than directly connecting every vehicle to every charging point, the pallet mediates the interaction by transporting vehicles to appropriate spaces, simplifying the overall system architecture.
2Device complexity
If charging and discharging devices are installed in limited parking spaces, then system complexity is reduced, but fewer electric vehicles can supply power to facilities
Solution Approach 1:
The movable pallet system enables dynamic redistribution of vehicles to the limited number of spaces equipped with charging/discharging devices. This maximizes the utilization of these devices by bringing the right vehicles to the right spaces at the right times, thereby enhancing power supply capability without increasing device count.
Solution Approach 2:
The system performs preliminary actions by proactively moving vehicles to charging/discharging spaces before power supply is needed. The controller identifies vehicles capable of power supply and positions them in advance in spaces with charging/discharging devices, ensuring immediate power availability when required.
3Loss of energy
If vehicles are moved to parking spaces with shorter feed lines, then power loss is reduced, but movement control complexity increases
Solution Approach 1:
The controller incorporates feedback mechanisms to monitor power loss levels and vehicle positions. Based on real-time information about feed line lengths and power transmission efficiency, the controller makes intelligent decisions about vehicle relocation, optimizing power loss reduction while managing control complexity through data-driven decisions.
Solution Approach 2:
The system changes the parameter of vehicle position to optimize power loss. By adjusting which vehicles are located in which parking spaces based on feed line length parameters, the system minimizes energy loss during power transmission from vehicles to facilities.
