Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles face inconvenience due to battery power shortages and the lack of nearby charging stations, leading to potential emergencies and inefficiencies in charging.
Innovation Solution
An information providing device and system that acquires vehicle location and power status data to select and notify available vehicles capable of supplying charging power to vehicles in need, using a vehicle assistance server to facilitate power transfer through a charging cable with authentication and payment processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vehicle relies on fixed charging stations for power supply, then charging infrastructure can be established, but the convenience and accessibility for vehicles in emergency situations is reduced
Solution Approach 1:
The patent introduces a mobile vehicle as an intermediary power source between the electrical grid and vehicles in need of charging. The mobile vehicle travels to the location of vehicles requiring power and establishes a direct charging connection, eliminating the need for fixed charging stations at every location while maintaining charging accessibility.
Solution Approach 2:
Vehicles with excess power capacity voluntarily participate in the power-sharing network by allowing their power to be transferred to vehicles in need. The system enables self-service charging where any vehicle can potentially serve as a charging source for others, distributing the charging function across the vehicle fleet rather than relying on centralized infrastructure.
2Adaptability or versatility
If power is transferred between moving vehicles, then charging flexibility is improved, but the system complexity and control requirements increase
Solution Approach 1:
The power transfer system is designed to be universal and compatible with multiple vehicle types and power storage units. The mobile vehicle can transfer power to any vehicle with a compatible power interface, and the system can operate in multiple modes (vehicle-to-vehicle charging, mobile vehicle recharging at stations, etc.), reducing the need for specialized equipment for different scenarios.
Solution Approach 2:
The system incorporates communication networks that enable real-time monitoring and control of power transfer operations. The mobile vehicle and receiving vehicles exchange information about power status, location, and charging requirements, allowing the system to dynamically adjust power transfer parameters and ensure safe, efficient operation despite the moving target environment.
3Duration of action of moving object
If vehicles carry larger power storage units, then self-sufficiency and range are improved, but vehicle weight and cost increase
Solution Approach 1:
The patent combines the power storage capabilities of multiple vehicles into a single operational unit through the mobile vehicle intermediary. Instead of each vehicle needing large individual power storage, the system merges the power resources of participating vehicles to provide sufficient charging duration, effectively distributing the weight burden across the fleet rather than concentrating it in individual vehicles.
Data Source
AI summary
It is an object to provide a system for assisting a vehicle on the edge of battery exhaustion. An information providing device includes: an information acquiring part for acquiring the current location of a vehicle and the amount of power stored in a power storage unit of the vehicle from a plurality of vehicles; a vehicle selecting part for selecting one or more vehicles as available vehicles for power supply from the plurality of vehicles based on the respective current locations and the amounts of stored power of the plurality of vehicles, the one or more vehicles to be selected being capable of supplying charging power to a target vehicle requiring charge of its power storage unit; and a notifying part for notifying of an available vehicle for power supply selected by the vehicle selecting part.
