EV Charging Switching Control for Flexible Charger Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electric vehicle charging infrastructure is inefficient and inflexible, leading to issues such as occupied charging points preventing vehicle charging and unoccupied points being reserved, failing to meet the mobility needs of increasing alternative energy vehicles.
Innovation Solution
A system comprising at least three individual chargers, a connection system, a switching system, and a control system that determines a connection map based on charging demand information to optimize charger usage, ensuring each vehicle is connected to at most one charger at a time, allowing for simultaneous charging of multiple vehicles with varying power requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If charging services are relocated from traditional stations to parking lots, then charging accessibility is improved, but charging point availability and flexibility deteriorate
Solution Approach 1:
The patent implements dynamic connection mapping that allows charging locations to be flexibly connected to different individual chargers based on real-time demand. The system can alternatively connect or disconnect charging locations from chargers, enabling adaptive resource allocation rather than static assignment. This resolves the contradiction by making the charging system dynamic and responsive to changing conditions.
Solution Approach 2:
The patent creates a universal charging network where multiple individual chargers can serve multiple charging locations through alternative connections. The switching system enables any charger to potentially serve any location, making the infrastructure multi-functional and adaptable. This universality allows the system to handle varying demands without requiring dedicated charging points at each location.
2Productivity
If multiple individual chargers are deployed to meet increasing vehicle demand, then charging capacity is improved, but system complexity and infrastructure cost worsen
Solution Approach 1:
The patent divides the charging infrastructure into multiple independent individual chargers that can operate autonomously. Each charger is a separate unit that can be connected to different locations as needed. This segmentation allows the system to scale capacity by adding individual units without requiring a complete system redesign, thereby increasing productivity while managing complexity through modular architecture.
Solution Approach 2:
The patent introduces a switching system as an intermediary that manages connections between individual chargers and charging locations. This mediator handles the complexity of routing and connection management, allowing multiple chargers to serve multiple locations without direct permanent connections. The switching system absorbs the complexity, enabling high charging capacity with manageable system architecture.
3Reliability
If charging locations are permanently assigned to specific chargers, then connection reliability is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent implements dynamic connection mapping that determines optimal connections between chargers and locations based on real-time conditions. Rather than permanent assignments, the system alternatively connects chargers to locations as needed, ensuring reliable charging when vehicles need it while maximizing charger utilization. This dynamic approach prevents both over-provisioning and under-utilization of charging resources.
