EV Rescue Trailer With Integrated Charging And Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles face challenges when stranded due to the inability to charge during towing, as existing rescue systems only retrieve and transport them without providing power, leaving the vehicle without power upon arrival.
Innovation Solution
A mobile electric vehicle rescue system equipped with a deployable platform, winch, ramp, and charging unit that allows for on-location or en-route charging, along with a systems analysis module for testing EV components, integrated with a trailer or vehicle, and powered by solar panels or generators for enhanced charging capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flatbed and winch are used to retrieve and transport a disabled EV, then the EV can be moved to a destination, but the EV remains without power throughout the transport process
Solution Approach 1:
The patent combines the rescue vehicle's towing function with a charging function by integrating a charging unit that can connect to the disabled EV. This merging of functions allows the EV to be both retrieved and charged simultaneously, eliminating the power deficiency issue during transport while maintaining the retrieval capability
Solution Approach 2:
The rescue vehicle is designed with multi-functionality, serving both as a towing platform and a mobile charging station. The charging unit can provide power to the disabled EV during transport, making the rescue vehicle capable of multiple operations (retrieval and charging) with a single system
2Use of energy by moving object
If a mobile rescue system with charging capability is deployed, then the EV can be charged during transport, but the system complexity increases
Solution Approach 1:
The rescue vehicle integrates multiple functions (towing and charging) into a single system. The charging unit is designed to work alongside the existing winch and flatbed components, allowing the same vehicle to perform both retrieval and charging operations without requiring entirely separate systems
3Reliability
If on-location charging is provided to stranded EVs, then the vehicle can be operational upon arrival, but additional charging infrastructure is required at the rescue vehicle
Solution Approach 1:
The rescue vehicle is equipped with a charging unit that functions as a mobile charging infrastructure. This unit can connect to the disabled EV and provide power during transport, ensuring the EV arrives operational without requiring external charging stations at the rescue location
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the retrieval, transport, and charging of disabled electric vehicles, providing valuable diagnostic information to customers while ensuring the vehicle is operational upon arrival, leveraging a network of independent providers for efficient roadside assistance.
Implementation Method 1
At least one PV panel can be associated with the mobile platform to charge batteries when a vehicle is not being transported
Implementation Method 2
A generator associated with wheels of the rescue vehicle can generate power as the rescue vehicle is moving on a road or highway while transporting a rescued vehicle

AI summary
An electrical vehicle (EV) rescue vehicle includes a mobile platform, which further includes a winch and a ramp. The mobile platform of the EV rescue vehicle is deployable for retrieving a disabled EV (a “rescued vehicle”) thereon with the winch and the ramp and for transportation of the disabled EV. A charging unit is associated with the mobile platform for connecting and charging of the disabled EV, either on a fixed location or during transport. A systems analysis module can be included with a system for testing a functionality of systems and components of the disabled EV and providing results of the resting EV to customers. The mobile platform can be provided as an EV rescue vehicle in a form of a trailer pulled by another vehicle or integrated with another vehicle (e.g., a truck). The EV rescue vehicle can also carry passengers associated with the disabled EV when the disabled EV is being transported, charged, and/or analyzed by the EV rescue vehicle.
