Mobile EV Wireless Charging Through In-Motion Vehicle Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicle range anxiety is caused by limited battery capacity, leading to time-consuming recharging and the inconvenience of finding available charging stations, which can divert from direct travel routes and cause delays.
Innovation Solution
A method for navigating a first surface-operating vehicle to synchronize with a second vehicle for wireless charging while in motion, using intelligent mobile units (IMUs) that follow and recharge EVs along routes, managed by a fleet management system that prioritizes charging based on factors like destination, weather, and user needs, allowing for inductive or resonance charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed charging stations are used for EV recharging, then charging infrastructure is established, but travel time increases and routes must be diverted
Solution Approach 1:
The patent transforms the static charging station model into a dynamic mobile charging vehicle system. The charging vehicle travels along with the EV, providing continuous charging services without requiring the EV to stop or divert to fixed locations, thereby reducing travel time while maintaining charging availability
Solution Approach 2:
The mobile charging vehicle acts as an intermediary between the power grid and the EV. It receives power wirelessly from overhead lines or other sources and transfers it to the EV through inductive charging, eliminating the need for direct connection to fixed charging stations and enabling continuous charging during motion
2Reliability
If fixed charging stations are used for EV recharging, then charging infrastructure is established, but travel distance increases due to route diversion
Solution Approach 1:
The mobile charging vehicle dynamically follows the EV along its intended route, eliminating the need for the EV to divert to fixed charging station locations. This maintains charging availability while preserving the directness of the travel route and minimizing additional travel distance
3Reliability
If on-board battery capacity is increased to extend range, then range anxiety is reduced, but vehicle weight and cost increase
Solution Approach 1:
The mobile charging vehicle provides continuous charging action while the EV is in motion, ensuring the battery remains continuously topped up without requiring large capacity reserves. This eliminates range anxiety by providing uninterrupted power supply rather than relying on increased battery capacity, thereby avoiding additional weight

Data Source
AI summary
A processing system including at least one processor of a first surface-operating vehicle may obtain a request for wireless charging of a second surface-operating vehicle while in motion. The processing system may then navigate the first surface-operating vehicle in synchronization with the second surface-operating vehicle and provide the wireless charging to the second surface-operating vehicle while in motion.
