Mobile EV Charging Route Control Using Road Surface Power Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery electric vehicles (BEVs) may run out of power while traveling, and existing rescue technologies are not reliable in ensuring timely and sufficient charging.
Innovation Solution
A server apparatus that communicates with vehicles to acquire information on required charge amount and position, and instructs a power supply vehicle to travel to a route with available road surface power supply to charge the BEV.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a power supply vehicle charges another vehicle directly, then charging can be performed without charging stations, but the power supply vehicle may not have sufficient remaining battery level to reliably rescue the vehicle needing charge
Solution Approach 1:
The patent introduces road surface power supply as an intermediary energy source. Instead of relying solely on the power supply vehicle's battery, the system uses embedded road surface power supply facilities to charge the power supply vehicle during its journey to the target location, ensuring it has sufficient energy to complete the rescue operation.
Solution Approach 2:
The system performs preliminary charging of the power supply vehicle by having it travel through routes with road surface power supply facilities before reaching the vehicle needing rescue. This advance energy replenishment ensures the power supply vehicle arrives with adequate battery level to perform the charging operation reliably.
2Adaptability or versatility
If the power supply vehicle travels to the vehicle needing charge, then mobile charging is enabled, but the power supply vehicle may arrive with insufficient charge to complete the rescue
Solution Approach 1:
The system enables continuous energy accumulation for the power supply vehicle by utilizing road surface power supply facilities along its travel route. The vehicle continuously charges while moving through designated areas, ensuring it accumulates sufficient energy before and during its mission to the vehicle needing rescue.
Solution Approach 2:
Road surface power supply facilities serve as an intermediary energy source between the power supply vehicle and the vehicle needing rescue. This intermediary system allows the power supply vehicle to replenish its battery during transit, ensuring adequate charge quantity for the rescue operation.
3Device complexity
If traditional vehicle-to-vehicle charging is used, then charging infrastructure dependency is reduced, but the rescue operation becomes unreliable when the power supply vehicle lacks sufficient charge
Solution Approach 1:
The system creates a multi-functional charging ecosystem where vehicles can charge each other directly, and power supply vehicles can simultaneously function as mobile charging units and as vehicles that recharge themselves using road surface facilities. This universal system maintains operational reliability without requiring traditional stationary charging infrastructure.
Solution Approach 2:
The road surface power supply acts as an intermediary that bridges the gap between reduced infrastructure dependency and maintained rescue reliability. It provides an alternative energy source that enables the vehicle-to-vehicle charging system to operate reliably without depending on traditional charging stations.
Data Source
AI summary
A server apparatus includes a communication interface, and a controller configured to communicate with vehicles using the communication interface, acquire information on a required charge amount and a position of a vehicle that needs to be charged, and provide instructions that a power supply vehicle that does not have the required charge amount is to travel a route where road surface power supply is available to the position.
