Parking Device Transport System for Electric Vehicle Charging Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parking facilities with electric vehicle charging infrastructure face inefficiencies due to the need for each parking space to be equipped with a charging station, leading to long charging times and high investment costs, especially in locations where not all vehicles require charging simultaneously.
Innovation Solution
Implementing a parking device with a transport system that automates the movement of electric vehicles to available charging stations, allowing for the optimization of charging device placement and power distribution, and using a charging controller to manage vehicle assignment and charging sequences based on vehicle state, expected parking time, and energy requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual charging stations with low charging capacity are installed at each parking space, then charging infrastructure coverage is improved, but charging time increases and investment costs rise
Solution Approach 1:
The system dynamically assigns vehicles to charging stations based on real-time charging requests and station availability. Instead of static one-to-one pairing, the transport device moves vehicles between parking spaces and charging stations according to current needs, optimizing charging time while maintaining infrastructure coverage
Solution Approach 2:
The transport device acts as an intermediary between parking spaces and charging stations. It shuttles vehicles to available charging stations, decoupling the relationship between parking space location and charging station location, thereby reducing charging time without requiring charging infrastructure at every parking space
2Adaptability or versatility
If charging stations are installed at every parking space, then charging availability is improved, but investment costs increase
Solution Approach 1:
Parking spaces serve multiple functions: some are equipped with charging stations for active charging, while others serve as waiting areas or storage for vehicles not currently needing charging. The transport device enables vehicles to access charging functionality from any parking space, making the entire parking facility universally accessible for charging purposes
Solution Approach 2:
The charging function is extracted from individual parking spaces and centralized at specific charging stations. Instead of embedding charging infrastructure in every parking space, the system separates parking functionality from charging functionality, with the transport device bridging the two, thereby reducing total investment while maintaining charging availability
3Ease of manufacture
If low charging capacity stations are used, then infrastructure installation is simplified, but charging speed decreases
Solution Approach 1:
The system performs preliminary assessment of charging requests, vehicle battery states, and station capacities before assigning vehicles to charging stations. This pre-planning allows optimal matching of vehicles with appropriate charging stations, maximizing charging speed while maintaining simple infrastructure design
Solution Approach 2:
The system dynamically adjusts charging parameters based on vehicle needs and station capabilities. By optimizing charging current and time allocation through intelligent control, the system achieves faster effective charging speeds even with stations of moderate physical capacity, without complicating the infrastructure
