Mobile Battery Swap Trailer for Remote EV Charging Autonomy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electric vehicles face limitations in autonomy due to battery power density, requiring a distributed network of charging stations, and existing mobile charging solutions are inadequate for remote and unstructured environments, while fixed battery swap stations lack mobility.
Innovation Solution
A trailer equipped with solar panels, wind turbines, and autonomous battery swapping capabilities, integrated with sensors and communication modules, enabling independent battery charging and swapping in remote locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed battery swap stations are used, then battery swapping capability is provided, but mobility and adaptability to remote locations are lost
Solution Approach 1:
The fixed battery swap station is segmented into a mobile trailer unit that can be transported to remote locations. The trailer contains all necessary battery swapping equipment, including battery racks, charging systems, and control mechanisms, allowing the functionality to be separated from fixed infrastructure.
Solution Approach 2:
The system transitions from a static fixed station to a dynamic mobile trailer that can be relocated. The trailer is equipped with towing capabilities and can be moved to different sites, providing adaptive battery swapping services wherever electric vehicles need support.
2Quantity of substance
If mobile charging devices are used, then portability is achieved, but total electric capacity and charging efficiency are limited
Solution Approach 1:
The mobile trailer contains multiple batteries nested within its structure, with battery racks holding several battery units. This nested arrangement allows the trailer to store substantial electric capacity while maintaining a compact, transportable form factor.
Solution Approach 2:
The trailer is equipped with autonomous battery swapping mechanisms that can operate without constant human intervention. The system includes automated guidance, battery handling, and charging functions that reduce the need for user operation while maintaining convenience.
3Reliability
If distributed charging stations are deployed, then autonomy support is improved, but infrastructure cost and deployment complexity increase
Solution Approach 1:
The mobile trailer is designed as a universal platform that can serve multiple functions: battery swapping, charging, and vehicle support. It can accommodate different electric vehicle types and battery configurations, reducing the need for multiple specialized infrastructure deployments.
Solution Approach 2:
The trailer acts as an intermediary between fixed charging infrastructure and remote vehicles. It can be transported to locations where vehicles need support, serving as a mobile intermediary that bridges the gap without requiring permanent infrastructure installation.
