Solution Overview
Problem
The adoption of electric vehicles (EVs) is hindered by limitations in battery range, charging time, and the lack of accessible charging stations, with current methods requiring vehicles to be stationary during charging and relying on fixed locations, which is inefficient and inconvenient.
Innovation Solution
The implementation of multi-level battery systems with different charge transfer rates and a cloud-based control system for peer-to-peer charging, allowing EVs to charge each other on-the-go and optimize charge distribution within a network, using algorithms to manage charge transactions and route adjustments for efficient energy transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles are charged at fixed charging stations, then charging infrastructure is established, but vehicles must be stationary during charging which reduces operational efficiency
Solution Approach 1:
Instead of having stationary charging stations charge parked vehicles, the patent inverts the approach by enabling moving vehicles to charge each other while in motion through peer-to-peer charge transfer, eliminating the need for stationary charging infrastructure and maintaining vehicle operational efficiency
Solution Approach 2:
The system enables vehicles to serve their own charging needs by allowing them to transfer charge to other vehicles directly, creating a self-sustaining charging network where vehicles are both charge sources and charge recipients without requiring external stationary charging infrastructure
2Duration of action of moving object
If battery capacity is increased to extend range, then vehicle autonomy is improved, but charging time increases and battery weight increases
Solution Approach 1:
Rather than requiring complete battery recharging, the system implements partial charge transfers between vehicles during operation, allowing vehicles to top up their batteries incrementally while moving, thus avoiding long charging times while still extending effective range
Solution Approach 2:
The charge transfer system enables continuous charging operation by allowing vehicles to exchange charge while in motion, maintaining the useful action of vehicle operation without interruption for stationary recharging, thus eliminating charging time loss from the operational cycle
3Productivity
If multi-level battery systems with different charge transfer rates are implemented, then charge distribution efficiency is improved, but system complexity increases
Solution Approach 1:
The battery system is segmented into multiple levels with different charge transfer rates, allowing simultaneous fast and slow charging operations, which improves overall charge distribution efficiency by matching different charging needs within the same system
Solution Approach 2:
The system dynamically adjusts charge transfer rates between different battery levels based on real-time operational needs, enabling flexible optimization of charge distribution efficiency while managing complexity through adaptive control rather than fixed configurations

AI summary
Apparatus, systems, and methods described herein relate generally to on-the-go entity-to-entity charging for multi-level battery-powered entities in transportation systems. A method can include determining charge levels, current positions, battery configuration, and transport speeds for an electric vehicle (EV), identifying one or more EVs in need of charging, and mobilizing a nearby EV for on-the-go peer-to-peer charging. A processor, with a memory including computer program code, can be configured to receive current charge level data for mobile battery-powered entities, identify one or more EVs to be charged and one or more other EVs that have excess charge to transfer, and send charging instructions to the EVs. A routing and charge transaction scheduling algorithm can be used to optimize the route of one or more battery-powered entities and to schedule charge transactions between EVs and/or a charging entity. A heuristic battery architecture compiler can be used to optimize battery architecture.
