Dynamic Charging Permission Management for Electric Vehicle Wireless Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle wireless charging methods cannot provide personalized charging services, leading to inefficient use of resources and waste at charging stations, as they only perform identity authentication without offering exclusive services based on individual vehicle requirements.
Innovation Solution
Implementing a method where wireless charging stations receive and manage charging requests from electric vehicles, including specific charging time and mode requests, and adjust charging permissions dynamically to match the configuration parameters of each vehicle, allowing for personalized charging and effective resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless charging station performs only identity authentication without personalized services, then the charging process is simple and fast, but resource utilization is low and waste occurs
Solution Approach 1:
The charging permission is made dynamic rather than static. The system adjusts charging permissions in real-time based on vehicle battery status, charging history, and current conditions. Different vehicles receive different permission levels (full permission, partial permission, no permission) that are dynamically updated, allowing the system to optimize resource utilization without requiring complex manual configuration for each vehicle.
Solution Approach 2:
The system implements feedback mechanisms where charging stations continuously monitor vehicle charging status, battery levels, and usage patterns. This feedback is used to adjust charging permissions and optimize resource allocation. The system learns from charging history and automatically refines permission assignments, improving resource utilization while maintaining manageable complexity through automated decision-making.
2Loss of energy
If wireless charging station provides personalized charging services for different vehicles, then resource waste is reduced, but the authentication and management process becomes more complex
Solution Approach 1:
Charging permissions are pre-configured for vehicles based on their characteristics, battery capacity, and expected usage patterns. This preliminary action allows the system to quickly determine appropriate charging parameters without complex real-time calculations, reducing both energy waste and authentication complexity. The pre-established permission framework enables efficient personalized service delivery.
Solution Approach 2:
The system uses parameter changes to manage complexity. Instead of complex rule-based authentication, it transforms the problem into parameter matching - comparing vehicle parameters (battery capacity, power requirements) with pre-defined permission parameters. This parameter-based approach simplifies the authentication process while enabling personalized charging that reduces energy waste.
3Productivity
If charging permission is uniformly applied to all electric vehicles, then the management process is simple, but charging efficiency and resource utilization are suboptimal
Solution Approach 1:
The system segments charging permissions into distinct levels (full permission, partial permission, no permission) and assigns them to different vehicles based on their specific needs. This segmentation allows the system to maintain operational simplicity through clear permission categories while achieving high charging efficiency by matching appropriate permission levels to appropriate vehicles, avoiding both over-charging and under-utilization.
