Robotic Arm EV Charger with Bid-Based Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles face limitations in driving range and charging intervals due to battery technology, and existing charging systems require manual intervention, which complicates vehicle ownership and adoption.
Innovation Solution
A dynamic electric vehicle charging system that uses a robotic arm with a docking interface to automatically align and couple with the vehicle's receptacle, allowing for autonomous charging and power transfer, with a resource management device allocating charging resources based on bids from multiple vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual connection is used for charging, then user control is maintained, but ease of operation deteriorates due to frequent manual intervention
Solution Approach 1:
The charging system performs self-service through automatic vehicle detection, robotic arm positioning, docking interface alignment, and charging initiation without user intervention. The system autonomously manages the entire charging process from detection to power transfer, eliminating manual connection requirements while maintaining user control through account validation and billing systems.
2Adaptability or versatility
If charging infrastructure is expanded, then availability improves, but device complexity increases due to resource allocation management
Solution Approach 1:
The resource management system dynamically allocates charging resources based on real-time vehicle bids and availability. The system adjusts power distribution, pricing, and allocation priorities dynamically rather than using static allocation methods, allowing efficient management of multiple vehicles and chargers without requiring overly complex predetermined scheduling systems.
3Manufacturing precision
If robotic arm positioning is used, then alignment precision improves, but device complexity increases due to articulation mechanisms
Solution Approach 1:
The system replaces complex mechanical positioning mechanisms with sensor-based detection and control systems. Vehicle detection uses sensors to identify vehicle presence and position, while the robotic arm employs feedback control to achieve precise docking interface alignment, reducing reliance on purely mechanical precision components.

AI summary
An electric charger resource sharing method and system comprise a charger that supplies electrical energy to a plurality of electric vehicles. The charger includes a robotic arm that articulates to be proximal to each of the electric vehicles for supplying the electrical energy to the electric vehicles and a docking interface at a distal end of the robotic arm that couples with a receptacle on each of the electric vehicles for transferring the electrical energy from the charger to the electric vehicles. A resource management device receives a bid from each electric vehicle, and allocates a portion of the electrical energy for a predetermined period of time to an electric vehicle of the plurality of electric vehicles in response to the bid of the electric vehicle.
