Charging Station Control System for Dynamic Parking Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional charging stations face inefficiencies due to idle parking spaces not corresponding with idle charging piles, leading to low land utilization and poor user experience, as the charging system and parking system are independent, causing vehicles to occupy spaces without corresponding charging availability.
Innovation Solution
A method and system that real-time monitor usage status, daily usage, and occupancy of both charging piles and parking spaces, determining available spaces for electric and fuel vehicles by integrating image information and historical data to ensure one-to-one correspondence between available charging and parking spaces, using ground locks and display devices to guide vehicles to appropriate spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the charging system and parking system are operated independently, then the system complexity is reduced and ease of operation is improved, but the land utilization rate deteriorates and charging efficiency is reduced
Solution Approach 1:
The patent merges the charging system and parking system into a unified management system. The control device integrates charging status information and parking space occupancy information, enabling coordinated management of both functions. This resolves the contradiction by combining previously independent systems to achieve better land utilization while maintaining operational simplicity through integrated control.
Solution Approach 2:
The unified management system performs multiple functions simultaneously: it manages charging operations, monitors parking space occupancy, determines available parking spaces, and provides guidance to users. This multi-functional approach allows the system to improve land utilization rate while keeping the ease of operation intact through a single integrated interface.
2Reliability
If dedicated charging stations are used for new energy vehicles only, then charging reliability is improved, but the land utilization rate deteriorates due to low vehicle numbers
Solution Approach 1:
The patent implements dynamic parking space allocation based on real-time charging status and vehicle type. Parking spaces are not fixed for specific vehicle types but are dynamically assigned based on current needs. This allows the station to adapt to varying vehicle numbers while maintaining reliable charging services, resolving the contradiction between charging reliability and land utilization.
Solution Approach 2:
The system changes the operational parameters of parking spaces based on charging status and vehicle type. By dynamically adjusting which spaces are allocated to fuel vehicles versus electric vehicles based on real-time data, the system maintains charging reliability for NEV while improving overall land utilization during periods of low NEV traffic.
3Productivity
If open charging stations allow fuel vehicles to occupy parking spaces, then land utilization rate is improved, but charging availability for new energy vehicles deteriorates
Solution Approach 1:
The system continuously monitors charging status information and parking space occupancy in real-time. Based on this feedback, it dynamically determines the quantity of available parking spaces for fuel vehicles versus electric vehicles. This feedback mechanism ensures that charging availability for NEV is maintained while allowing fuel vehicles to utilize spaces when charging is not needed, resolving the contradiction between land utilization and charging availability.
Solution Approach 2:
The control device preliminarily determines the quantity of available parking spaces for different vehicle types based on predicted charging needs and current status. By proactively allocating spaces before vehicles arrive, the system ensures charging availability for NEV while optimizing land utilization for fuel vehicles during non-peak periods.
4Loss of information
If real-time monitoring of charging and parking status is implemented, then information accuracy is improved and user experience is enhanced, but device complexity increases
Solution Approach 1:
The patent introduces a control device as an intermediary that centralizes the collection, processing, and management of charging status information and parking space occupancy information. This intermediary consolidates data from multiple sources, providing accurate real-time information to users while simplifying the overall system architecture compared to distributed monitoring solutions.
