Solution Overview
Problem
Existing power management systems for vehicles that share a power supplying vehicle among multiple power receiving vehicles are inefficient in managing battery charge without stopping the receiving vehicles during charging.
Innovation Solution
A power management system that includes travel control and communication units in both power supplying and receiving vehicles, allowing them to coordinate and perform non-contact charging by adjusting travel routes and distances to maintain battery charge without halting the receiving vehicles, with optional features like battery monitoring and prediction for efficient charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a power supplying vehicle is shared among multiple power receiving vehicles, then the number of charging facilities is reduced, but the management of charging between multiple power receiving vehicles becomes inefficient
Solution Approach 1:
The system dynamically adjusts the travel routes of both the power supplying vehicle and power receiving vehicles in real-time based on charging requests, battery status, and route information. The control unit optimizes the merging of routes to enable efficient charging while maintaining vehicle mobility and sharing capabilities among multiple vehicles.
2Productivity
If non-contact charging is performed while the power receiving vehicle travels, then the power receiving vehicle does not need to stop for charging, but the power supplying vehicle cannot be effectively shared among multiple power receiving vehicles
Solution Approach 1:
The system receives charging start requests and route information in advance, allowing the control unit to pre-calculate optimal merging routes for the power supplying vehicle. This preliminary route planning enables the power supplying vehicle to be positioned correctly before the power receiving vehicle arrives, facilitating effective sharing among multiple vehicles while maintaining continuous travel capability.
Solution Approach 2:
The system continuously monitors battery remaining charge, charging status, and vehicle positions, using this feedback to dynamically adjust routes and coordinate charging activities. This real-time feedback mechanism enables efficient management of the power supplying vehicle across multiple power receiving vehicles while maintaining continuous operation.
3Ease of operation
If the power receiving vehicle stops for charging, then charging management is simpler, but the power receiving vehicle loses continuous travel capability
Solution Approach 1:
The system replaces the traditional mechanical stopping and connecting action with a non-contact charging mechanism using electromagnetic fields. The power transfer occurs through field interaction between the power supplying vehicle and power receiving vehicle, eliminating the need for physical connection and stopping, thereby maintaining continuous travel capability while simplifying charging management.

AI summary
A second communication unit of a power receiving vehicle sends a charging start request signal to a power supplying vehicle located on a planned travel route of the power receiving vehicle. At least one of a first travel control unit of the power supplying vehicle and a second travel control unit of the power receiving vehicle brings the power supplying vehicle and the power receiving vehicle close to each other up to a position that satisfies a charging start condition when the first travel control unit receives the charging start request signal from the power receiving vehicle through a first communication unit of the power supplying vehicle. The remaining charge of a battery of the power receiving vehicle is managed by performing charging between the power supplying vehicle and the power receiving vehicle.
